Elevator to extinction (cartoon)
As climate change pushes montane species upslope in a bid to escape warming temperatures, species, including birds, occupying the highest altitudes could be left with nowhere to go, making them the most prone to extinction.
In Panama, Indigenous Guna prepare for climate exodus from a second island home
- The island of Uggubseni, located in Panama’s Guna Yala provincial-level Indigenous region, spent the month of February participating in region-wide celebrations to mark the centenary of a revolution in which the Indigenous Guna expelled repressive Panamanian authorities and established their autonomy in the region.
- Though the intervening century has left the Guna’s fierce independence undimmed, new existential threats now face Uggubseni: Accelerating sea level rise due to human-caused climate change and overpopulation.
- A consensus now exists among Uggubseni residents that moving inland is necessary; but it remains unclear whether the government will be able to deliver the necessary funding and support.
- Although 63 communities nationwide are at risk of sinking due to climate change, there’s only one other model for climate relocation: In June 2024 the Panamanian government relocated around 300 families from Gardi Sugdub, another island in Guna Yala, to a new community on the mainland where problems remain rife.
122 companies responsible for a third of present day sea-level rise: Study
What’s new: Almost half of global average temperature rise and a third of sea-level rise can be attributed to the “carbon majors,” the world’s 122 largest fossil fuel and cement producers, a recent paper shows. What the study says: Research from U.S.-based science advocacy NGO Union of Concerned Scientists (UCS) used climate-carbon cycle models, and […]
Colombian farmers switch from coffee to cacao as temperature and prices soar
- Due to rising temperatures and climate change, small-scale coffee farmers in Colombia are increasingly planting cacao.
- Cacao faces fewer immediate challenges compared to coffee, which is prone to pests and diseases, and can integrate well into agroforestry systems. However, agronomists warn that the switch to cacao can lead to clearing forests and increasing chemical inputs in order to expand existing plantations.
- Higher profits, the high prices of cacao in the market, and the increasing expenses needed to manage coffee crops are also factors pushing small-scale farmers towards the switch.
- Although coffee remains Colombia’s most important agricultural product, cacao is emerging not just as an alternative, but as a defining crop in Colombia’s evolving agricultural future, say agronomists.
Farmers turn to living ‘yam sticks’ to grow their crop and spare the forest
- In major yam-producing areas such as West Africa and the Caribbean, the tuber is traditionally grown using sticks as scaffolds for vine growth, which are traditionally cut from the forest, causing deforestation.
- Scientists and yam breeders are trialing ways to replace these sticks through agroforestry, introducing living supports that can also improve the soil and provide other benefits to farmers.
- Trials using plants such as pigeon pea and bitter damsel as living yam sticks have shown potential.
- However, conservationists say that entrenched traditional farming methods and a lack of funding to promote more sustainable approaches are preventing living vine sticks from widespread application.
Ground-level ozone pollution poses growing threat to planetary health
- In the stratosphere, ozone acts as a protective layer. But in the troposphere, at ground level, this colorless gas is incredibly harmful to human health and the environment in ways scientists are still working to fully understand. The problem exists worldwide, but may become especially bad in tropical nations this century.
- Ground-level ozone is a major air pollutant that shortens human lives and kills thousands each year, resulting in major economic impacts. It is formed when methane, nitrogen oxides and volatile organic compounds (released from vehicles, industry, power plants and crops) react in the presence of sunlight.
- Climate change worsens tropospheric ozone, with higher temperatures accelerating the chemical reaction that creates it, and because stalled weather systems (especially heat domes) allow buildup of ozone in stagnant polluted air. Ozone pollution not only impacts urban area, but also rural agricultural areas.
- Ozone impacts on biodiversity are significant and growing — harming pollinators, reducing crop yields and limiting forest growth, with global implications for food security and humanity’s reliance on forests as carbon sinks. Effectively tackling climate change and reducing ozone precursors are major solutions.
Longer periods of drought threaten Brazilian amphibians
- According to a study, global warming will increase droughts in up to 33% of the habitats of frogs, toads and treefrogs; in Brazil, the strongest impacts will be felt on the Amazon and the Atlantic Forest — precisely those with the greatest diversity of amphibians.
- Drought and amphibians are not a viable combination: These animals depend on water and humidity to survive; without that, they may dehydrate in a few hours and die.
- The Atlantic Forest is home to more than 700 species of anuran amphibians, more than 50% of which are endemic; in the Amazon, the greatest focus of potential extinction is the Arc of Deforestation.
- In a warmer and drier climate, the question is whether there will be time for these animals to adapt or evolve over generations to survive these new conditions.
In Pakistan, sea level rise & displacement follow fisherfolk wherever they go
- Rising sea levels are displacing fisherfolk in Pakistan’s coastal areas, forcing them to move to higher ground, such as Karachi, where they now face saltwater intrusion and other climate impacts.
- For many, this displacement is not just about losing homes, but also cultural heritage, traditions and livelihoods, with women, in particular, losing economic freedom as fishing communities decline.
- The Pakistani government lacks a formal policy for the voluntary migration of climate refugees, and while efforts like mangrove restoration have been attempted, they have not significantly alleviated the fishing community’s problems.
- Karachi is projected to receive 2.3 million climate migrants by 2050, primarily due to rising sea levels, saltwater intrusion, and other climate-related catastrophes.
Polar sea ice continues steep decline; but will a troubled world notice?
- Polar sea ice has reached record, and near-record, lows for this time of year, pushing the pace of global warming and alarming scientists. The just declared 2025 Arctic sea ice extent winter maximum is the lowest on record, at 14.33 million km² (5.53 million mi²). That’s 80,000 km² (31,000 mi²) below the previous low seen on March 7, 2017.
- The 2025 Antarctic sea ice extent summer minimum on March 1 tied for the second lowest on record, at 1.98 million km² (764,000 million mi²). The all time record Antarctic summer low was 1.79 million km² (691,000 million mi²) reached on February 21, 2023. Polar ice satellite records have been continuous since 1979.
- Sea ice loss is expected to continue its slide based on climate models, with scientists warning that the Arctic landscape is likely to be transformed beyond recognition within decades. Sweeping changes will devastate Indigenous polar communities, disrupt Arctic ecosystems, and ultimately lead to the demise of iconic polar wildlife.
- Inhospitable polar conditions continue challenging scientists’ ability to gather data and make precise polar forecasts vital for knowing our climate future. But it may be even more challenging to raise public awareness and political will to reduce carbon emissions and reverse polar ice loss before it passes dangerous tipping points.
Expedition links Antarctic glacial melting to climate catastrophe in Brazil
- A team led by Brazilian researchers carried out a 70-day expedition around Antarctica to understand the melting rate of glacial ice and to see how the region is reacting to global warming.
- The changes in the landscape that the researchers encountered were shocking, leading them to predict that Brazil’s climate will be increasingly affected by warming in Antarctica.
- In the shadow of the 2024 floods, the greatest climate tragedy it has seen in history, the state of Rio Grande do Sul should prepare itself for the same sort of event to happen again within the next 30 years, they warn.
Africa’s last tropical glaciers are melting away along with local livelihoods
- Africa’s remaining tropical glaciers are rapidly disappearing as greenhouse gas emissions drive global warming.
- New maps published by Project Pressure show the Stanley Plateau glacier, in Uganda’s Rwenzori Mountains, lost nearly 30% of its surface area between 2020 and 2024.
- The Rwenzoris’ glaciers are a vital source of water for more than 5 million people living in the plains below the mountain range; they also have cultural significance.
- Project Pressure’s ongoing surveys, carried out in collaboration with the Uganda Wildlife Authority, are intended to provide local authorities with data needed to adapt to the loss of the glaciers and other impacts of climate change.
With climate change, cryosphere melt scales up as a threat to planetary health
- Earth’s cryosphere — comprised of ice sheets, glaciers, permafrost and snowfall — is in a rapid state of flux due to escalating climate change, with numerous studies underlining the grave risks posed by the thaw.
- Today, that worldwide meltdown poses new threats to human lives — endangering freshwater supplies and food security while increasing the risks of natural disasters and disease outbreaks. Cryosphere loss poses immense dangers to the environment, agriculture, economy and society according to a new report.
- If emissions continue unabated, these problems will only worsen. Scientists warn of compounding risks as cryosphere melt escalates, including sea level rise, the slowing of ocean currents, and the triggering of feedbacks that will add to climate change.
- 2025 is designated the International Year of Glaciers’ Preservation. Experts are calling for drastic cuts to carbon emissions because each fraction of a degree of warming avoided counts toward the preservation of the cryosphere along with the ecosystem services that ice, snow and permafrost provide.
Australia faces inflation, agriculture losses after Cyclone Alfred
The Australian government has warned of impacts to the country’s economy in the wake of Cyclone Alfred that caused massive losses to infrastructure, agriculture and the dairy industries when it struck in late February. The horticultural industry was among the worst hit, with strong winds toppling and damaging hundreds of orchard trees, and floodwaters inundating […]
Lake Chad isn’t shrinking — but climate change is causing other problems
- Contrary to popular conception, Lake Chad is not shrinking; new research shows that the volume of water in the lake has increased since its low point in the 1980s.
- However, more intense rain in the region, coupled with the impacts of historic drought, increases the risk of flooding.
- The region is also plagued by continuing conflict and insecurity, making to harder for people to adapt to the impacts of climate change.
- A Lutheran World Federation project is working with communities in the Lake Chad Basin on sustainable agriculture and fisheries, land restoration, conflict resolution and more.
After LA, fire crisis reaches Latin America — from Mexico to Argentina
- As the effects of climate change become increasingly evident, Latin American countries are facing complex circumstances when it comes to defending themselves against forest fires — and urban fires.
- In Argentinian Patagonia, fires have destroyed more than 10,100 hectares (24,958 acres) of native forests, including areas of Nahuel Huapi National Park. There are also active fires in Chile that have killed three firefighters.
- Mongabay Latam talked to specialists in order to understand what is happening in some of the territories that have been hit hardest by the fires.
- Experts agree that it is urgent for Latin American governments, which often have limited capacity, to double down on their prevention efforts and allocate sufficient resources to fire management strategies, taking timely action against forest fires.
Brazil has seen a 460% increase in climate-related disasters since the 1990s
- An unprecedented study analyzed data from 1991 to 2023 and found that each 0.1°C increase in average global air temperature led to 360 new climate disaster events and damages in Brazil amounting to R$ 5.6 billion ($970 million).
- The global warming process has accelerated over the current decade, resulting in an average of 4,077 recorded climate-related disasters per year in Brazil, compared to 725 per year during the 1990s — an increase of 460%.
- The extreme events recorded over the period — totaling 64,280 — include droughts, floods and storms in 5,117 Brazilian municipalities; over 219 million people were affected, 78 million of whom during the last four years.
- Despite the increased number of disasters and the damage they caused, Brazil’s federal budget for risk and disaster management has been cut every year between 2012 and 2023 by an average of R$ 200 million ($34.6 million) per year.
January 2025 was warmest on record as climate change ‘overwhelms’ La Niña’s cooling
January 2025 was the warmest January on record, surpassing the previous record set by January 2024, according to satellite data from the EU’s Copernicus program. The findings were unexpected as ongoing La Niña conditions in the Pacific typically cool down global temperatures. The global average surface air temperature for the month reached 1.75° Celsius (3.15° […]
Indonesia mulls Paris Agreement exit, citing fairness and energy transition costs
- Indonesia is considering withdrawing from the Paris Agreement, arguing it is unfair for developing nations to comply when a major polluter like the U.S. has pulled out, again.
- Officials highlight Indonesia’s lower per capita emissions and stress the need for more financial aid to transition away from coal.
- Environmental groups warn that exiting the agreement could harm Indonesia’s economy, global reputation, and ability to secure climate funding.
- While Indonesia signed a $20 billion Just Energy Transition Partnership (JETP) deal in 2022, slow fund disbursement has fueled frustration, and coal remains central to its energy strategy.
The warming Arctic is now a carbon source, report finds
- A combination of increased microbial activity, thawing permafrost, and more frequent wildfires now means the Arctic is releasing more carbon dioxide than it’s storing, according to the 2024 Arctic Report Card.
- The temperature has also been rising; the past nine years have been the warmest on record in the Arctic.
- The changes have affected the region’s wildlife, with migratory tundra caribou populations declining by 65% over the past two to three decades.
- The report concludes that supporting Indigenous leadership, ways of life, and sustained climate action will be crucial for understanding and responding to rapid Arctic change.
Climate researcher fired for refusing air travel wins compensation
A climate researcher who was fired from his job for refusing to take a flight back from a work trip has been awarded compensation in court for unfair dismissal. Gianluca Grimalda has been reducing his air travel since 2010. But in 2023, his employer, the Kiel Institute for the World Economy (IfW) in Germany, terminated […]
‘Unusual’ and weak La Niña confirmed, offers cooling respite after record El Niño
It’s official: a weak La Niña came into fruition in late December and is expected, with significant uncertainty, to last until sometime between February and April, the U.S. National Oceanic and Atmospheric Administration announced. La Niña often brings wetter conditions to Southeast Asia and the Brazilian Amazon, while cooling global temperatures overall, potentially easing recent […]
Global ocean temperatures set new record in 2024
- Average temperatures across the world’s oceans reached an all-time high in 2024, according to a multi-team study published Jan. 10.
- The temperatures surpassed even those of 2023, which themselves represented a marked uptick over any previous years on record.
- Each of the two main metrics for ocean temperature hit a record high in 2024, while a commonly cited overall metric that accounts for both land and sea temperatures also reached a new high.
- The findings fit with a decades-long trend of ocean heating. The long-term rise is both a result of climate change and a cause of climate change effects like sea-level rise and increased likelihood of extreme weather.
Global temperature in 2024 hits record 1.55°C over pre-industrial level
The year 2024 was the hottest on record, with an average temperature of 1.55° Celsius (2.79° Fahrenheit) higher than pre-industrial levels, surpassing the previous record set in 2023, according to six international data sets. Scientists caution that the data represent the average for the Earth’s year-round weather and don’t mean that the climate has exceeded […]
At least 11,500 deaths linked to extreme weather in 2024
Extreme weather in 2024 affected around 18 in every 1,000 people across the globe, according to preliminary figures from the International Disaster Database. Mongabay has compiled the data into an interactive dashboard below. Intense droughts, floods, storms, heat waves and other climate-driven disasters claimed more than 11,500 lives and affected at least 148 million people […]
Direct air capture climate solution faces harsh criticism, steep challenges
- Direct air capture — geoengineering technology that draws carbon dioxide from the air, allowing it to be stored in geologic formations or used by industry — is being heavily hyped as a climate solution.
- But as direct air capture (DAC) pilot projects an startups grow in number around the world, fueled by investment and government funding in the U.S. and elsewhere, this proposed climate solution is becoming ever more divisive.
- Critics paint DAC as a costly, ineffective distraction from drastically slashing fossil fuel extraction and emissions. The use of captured carbon by the fossil fuel industry to squeeze ever more oil from wells comes in for particularly sharp criticism.
- Though carbon dioxide removal (CDR) may be needed to help limit the worst impacts of global warming, experts say betting on direct air capture is riddled with challenges of cost and scale. Two hurdles: sourcing sufficient renewables to power DAC facilities, and minimizing carbon-intensive DAC infrastructure.
Indonesian forests put at risk by South Korean and Japanese biomass subsidies
- Subsidies for forest biomass energy in Japan and South Korea are contributing to deforestation in Southeast Asia, according to an October 2024 report by environmental NGOs. The biomass industry is expanding especially quickly in Indonesia; the nation is exporting rapidly growing volumes of wood pellets, and is burning biomass at its domestic power plants.
- Japanese trading company Hanwa confirmed that rainforest is being cleared to establish an energy forest plantation for wood pellet production in Indonesia’s Sulawesi Island. Hanwa owns a stake in the project. The wood pellet mill uses cleared rainforest as a feedstock while the monoculture plantation is being established.
- A Hanwa representative defended the Sulawesi biomass project by claiming the area consists of previously logged secondary growth and that the energy plantation concession is not officially classified as “forest area.”
- The Japanese government is supporting biomass use across Southeast Asia through its Asia Zero Emission Community initiative, begun in 2023.
India, U.K. deal with storms that are ‘symptom of our changing climate’
India is bracing for intense rainfall over the next few days as a deep depression over the Bay of Bengal is set to intensify into what will be called Cyclone Fengal by Nov. 29, according to local media reports. The India Meteorological Department (IMD) said the cyclone is likely to pass near the coast of […]
How a holistic approach aims to heal mangroves in Guinea-Bissau
- Though small, Guinea-Bissau has sizable amounts of mangroves, which cover 9% of this West African country.
- Farmers clear patches of mangroves to grow rice, but climate change and socio-economic shifts mean that many hectares of former rice fields lie abandoned, and could be restored.
- Wetlands International is using an approach called Community-based Ecological Mangrove Restoration (CBEMR) to regenerate abandoned rice fields in and around Cacheu and Cantanhez national parks; 2,600 hectares have been restored to date.
- Community involvement is a cornerstone of the approach, and the project also supports income generation and educational activities.
Organizations tackle droughts, floods in Brazil by planting forests
- Many areas of Brazil have been hit with severe droughts and floods in recent years; scientists say climate change is increasing the incidence of extreme weather events.
- Forests protect against erosion and pollution and help store water in soil and aquifers, buoying water security.
- Organizations across the country are leading efforts to reforest cleared areas — particularly along rivers and other water sources —to mitigate the damaging effects of droughts, floods and other effects of climate change, as well as safeguard and improve habitat for wildlife.
- Experts and stakeholders say broader support is needed at the federal level, while a representative of Brazil’s Ministry of Environment and Climate Change says the government is rolling out conservation plans of its own.
U.S. policy experts confident of future climate action despite Trump election
- In 2015, the world came together to achieve the landmark Paris climate agreement. But in 2016, Donald Trump’s ascendency to the U.S. presidency stunned the world, as he promised to withdrew the U.S. from the Paris accord and moved to disrupt action on climate change.
- The Biden administration worked to reverse that damage, with the U.S. again taking a leadership role in global climate summits and passing the Inflation Reduction Act, one of the most ambitious U.S. laws ever to combat global warming and boost the post-carbon economy.
- Now, with Trump elected again, the world stands ready for his climate denialism, and his likely withdrawal of the U.S. for a second time from the Paris Agreement. Global momentum is expected to continue unabated, with alternative energy thriving, Brazil hosting COP30 in 2025, and China and the EU doubling down on climate action.
- In the U.S., “Just as we did during the last Trump administration, we are going to put a focus on our work with cities and with states and many private-sector leaders who stood tall then and stand tall now,” said Gina McCarthy, EPA administrator during Barack Obama’s second term, and managing co-chair of America Is All In, an NGO.
Atmospheric methane removal: A promising but challenging climate solution
- Methane is currently responsible for about one-third of global warming. This greenhouse gas is about 80 times more potent than carbon dioxide in terms of its ability to heat up the climate system, though methane molecules only persist in the atmosphere for seven to 12 years before breaking down.
- Methane emissions are a major cause for concern, as they’ve been increasing at record speeds the past five years. At least two-thirds of annual methane emissions now come from human activities, including livestock, agriculture, fossil fuels, and landfills and other waste. Climate change is also increasing methane releases.
- Removing atmospheric methane is a tempting prospect as a climate change-curbing strategy. Multiple geoengineering approaches are being considered, but research remains limited and largely theoretical, while environmental impacts largely remain unknown and underexplored.
- Researchers say methane removal technologies, such as the iron salt method, should be investigated to break down atmospheric methane molecules. But scientists interviewed for this story repeatedly emphasized the most urgent need is to simultaneously make rapid deep cuts to human-caused methane emissions.
Climate change drives rise in rainfall, ‘Christmas typhoons’ in Philippines
The Philippines experienced an increase in “Christmas typhoons” and tropical cyclone-induced rainfall over the last couple of decades, according to the country’s latest climate report.
Arctic sea ice hits summer minimum; Antarctic hovers at new winter lows
- The Antarctic winter sea ice maximum is on track to be the second lowest on record, at 17.15 million square km² (6.62 million mi²), close to the 2023 record low of 16.96 million km² (6.55 million mi²). Some scientists see this as anomalous. Others see it as a shift in the southern polar environment, maybe triggered by climate change.
- The Arctic summer sea ice minimum also stayed low this year, at 4.28 million km² (1.65 million mi²), making it the 7th lowest minimum in the satellite record. So far, 2012 saw the record minimum of 3.41 million km² (1.32 million mi²).
- Polar sea ice losses have global impacts. In one analysis, researchers estimated the planetary cooling effects of Arctic and Antarctic sea ice during 2016-2023 were about 20% and 12% less, respectively, than they were during 1980-1988, leading to almost 15% less cooling power for the planet.
- With about 12% declines of Arctic Ocean ice each decade, researchers predict a nearly ice-free Arctic summer by 2050, allowing more shipping through the Northwest Passage but threatening this unique polar ecosystem. Studies also show the Antarctic ice sheet to be increasingly at risk, particularly Western Antarctica.
Amazon lakes overheat as record drought drives dolphin deaths
Severe drought and soaring temperatures are causing lakes and rivers in the Amazon to reach dangerously high temperatures, threatening species like the Amazon river dolphin, according to a recent study’s preprint. In 2023, the Amazon experienced its worst drought in recorded history, coupled with the hottest dry season on record. The extreme climate caused the […]
Global carbon capture and storage potential way overblown, study finds
A new study finds that the potential for carbon capture and storage is much more limited, by a factor of five or six, than the capacity projected by the United Nations to fight climate change. The U.N.’s Intergovernmental Panel on Climate Change estimates a maximum of 30 gigatons of carbon dioxide can be trapped underground […]
In the Brazilian Amazon, seedlings offer hope for drying rivers
- In Brazil’s Maranhão state, the advance of monoculture and decades of forest destruction have driven a shift in precipitation patterns, diminishing rains and drying out springs that feed important rivers.
- This represents a major threat for the Guajajara Indigenous people, for whom these springs hold spiritual significance and guarantee the health of the rivers they depend on for fishing, bathing, drinking and cultural rituals.
- In an effort to restore drying springs, Indigenous people in the Rio Pindaré reserve are mapping headwaters and planting species native to the Amazon rainforest – like buriti, pupunha and açaí palms – along their margins.
- Scientists say this type of reforestation could help restore balance to water cycles in the region, mitigating the broader impacts of drought and climate change.
Arctic melt ponds influence sea ice extent each summer — but how much?
- July marks the midpoint of the summer sea ice melt season, during which ice declines rapidly under the almost constant Arctic sun, and melt ponds form on ice floes. Scientists study melt ponds to better understand sea ice dynamics and to help forecast the annual sea ice minimum in September.
- Sea ice melt ponds absorb more solar energy than bare ice or snow but far less than open ocean, which complicates the story of summer sea ice melt. But in the past, scientists lacked the tools to accurately measure melt pond impacts.
- New remote sensing data look at sea ice from different satellite resolutions. High-resolution imaging sends a clear picture of melt ponds in a very small area, while low-resolution imaging produces a fuzzy picture of them across the entire Arctic.
- A combination of satellite data and on-the-ice observations now help scientists track the evolution of sea ice melt ponds and their influence on the overall decline of sea ice in the Arctic.
South Africa adopts a new climate change law
South African President Cyril Ramaphosa recently signed into law a new climate change act, the first of its kind for the country. The legislation aims to both reduce the country’s greenhouse gas emissions and mitigate and adapt to the effects of climate change already baked into the global system. The new law aims to set […]
In Brazil’s Amazon, land invasions — and fires — threaten a protected reserve
- In Brazil’s state of Maranhão, one of the last slices of remaining rainforest is under threat from invasions and fires, which has complicated efforts to protect this area of rich biodiversity from the advance of agriculture and cattle ranching.
- Over the last 12 months, satellites detected 122,083 high-confidence deforestation alerts within the Gurupi Biological Reserve, home to species such as the Kaapori capuchin (Cebus kaapori), one of the world’s most critically endangered primates.
- Authorities have struggled to gain control over the region, which has been marked by a complex history of illegal logging and land settlement. More than 6,000 people still live within the conservation area.
- As deforestation advances, the climate is changing and leaving this region of the Amazon Rainforest drier and more prone to wildfires, which pose a risk to neighboring Indigenous territories like the Carú reserve.
Global lakes are in hot water amid climate change
Lake surface temperatures are rising globally and are expected to continue to increase due to climate change. New research indicates that lake temperatures could exceed natural variability within this century, especially in tropical lakes. This unprecedented warming, and the disappearance of existing climates “could lead to the extinction of some species and the redistribution of […]
Biomass power grows in Japan despite new understanding of climate risks
- New biomass power plants continue to come online in Japan, requiring an ever-greater quantity of imported fuel. The government’s feed-in tariff scheme, which has been tweaked but not canceled, incentivized these projects.
- Although understanding of forest biomass’s negative environmental and climate impacts is growing in Japan, policy advocates say operators of existing biomass power plants need to pay back construction bank loans, and the government’s refusal to admit its mistake is keeping biomass plants running.
- A major biomass fuel type is wood pellets, which in Japan is presently primarily sourced from plantation forests in Vietnam and primary forests in British Columbia, Canada. While BC ecologists have spoken out against wood pellets, and found allies in Vietnam, the biomass issue has proved challenging for Japan’s forest advocates.
- Though historically a small source of wood pellets for Japan, the growing popularity in Indonesia of pellets for both export and domestic use risks tropical forests there being cleared to make way for biomass energy plantations, NGOs warn.
Biochar could play big role in Bhutan’s carbon storage — but it’s news to farmers
- A new study shows that Bhutan has the potential to sequester 68% of its greenhouse gas emissions through biochar, a carbon-rich material made from organic waste that is used to help plants grow.
- The research shows that using crop residue as mulch and biochar can significantly increase yields; however, many farmers in Bhutan do not know about biochar nor do they have access to the raw materials, such as rice husks, necessary for its production.
- While many studies note biochar’s potential for mitigating climate change, some research shows that too much biochar under certain conditions can harm soil, soil organisms and water availability and can cause soil erosion.
In northern Spain, climate change is killing shellfish — and women’s livelihoods
- In Galicia in northwestern Spain, shellfish harvesting is traditionally women’s work.
- But the clams and cockles the shellfish pickers’ livelihoods depend on are increasingly harder to come by.
- Extreme weather events made more frequent and intense by climate change, including heat waves and torrential rain, threaten the four main shellfish species harvested in the region, and with them, the tradition that has been passed down through generations of women.
Indigenous Alaskans drive research in a melting arctic
- In Utqiagvik, Alaska, the Iñupiat rely on whaling and subsistence hunting for the bulk of their diet, a practice dating back thousands of years.
- Powered by mineral wealth, the Iñupiat-run North Slope Borough Department of Wildlife Management employs a collaborative team of scientists and hunters.
- Though the arctic is warming nearly four times faster than the global average, the Iñupiat are confident in their ability to adapt their practices to changing conditions.
- The Department of Wildlife Management provides a potential model for collaborations between Indigenous peoples and western researchers — with Indigenous leaders in charge of funding and resource allocation.
An ancestral solution ensures water for Peruvian alpaca farmers, but is it enough?
- A community of alpaca farmers in the high Peruvian Andes is witnessing the loss of its mountain glaciers as a result of a warming climate and unseasonal droughts.
- In response, community members have turned to an ancestral practice of harvesting rainwater runoff and snowmelt, caching it in artificial lagoons that they can then tap to irrigate their alpaca pastures.
- Today, the community of Santa Fe, on the slopes of Mount Rit’ipata, has 41 of these lagoons, or qocha, but increasingly prolonged droughts mean it will need many more.
- Other communities across Peru have launched similar water harvesting initiatives, and while the government backs these projects, communities like Santa Fe are ineligible for state funding under a 2022 regulation.
Marshallese worries span decades — first nuclear tests, now sea-level rise
- The Marshall Islands were the site of numerous U.S. nuclear tests in the 1950s that displaced communities and altered their way of life.
- Locals across the islands and atolls are now at risk of evacuation and losing more of their ties to the land if sea-level rise continues at its current rate.
- For many Marshallese elders, their connection to the land is deeply rooted in their mind, body and soul: It is an integral part of their identity and culture.
- Elders talk about their concerns for the future and explain their intimate connection to their land.
Polar warning: Warming temperatures mean more than melted ice
- The Arctic and Antarctic are changing rapidly in response to global warming, with scientists striving to understand how escalating impacts on these unique regions impact the rest of the world. This story summarizes three significant recent studies.
- A new comprehensive greenhouse gas budget for Arctic terrestrial ecosystems estimates that the permafrost-covered region now emits more greenhouse gases — including carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) — than it stores. That trend is expected to accelerate if Arctic warming worsens further.
- Another recent study looked at the ice shelves edging the Antarctic continent, which act as brakes slowing the flow of glacial ice into the ocean that adds to sea-level rise. Although many factors impact the mass and stability of these shelves, a new model shows El Niño warming events help melt ice from below to increase shelf loss.
- Scientists also analyzed a record-breaking heat wave hitting Antarctica in March 2022, when temperatures soared by up to 40°C (72°F) above normal. They determined that this “black swan” event is having long-term impacts on the region’s ecosystems. The odds are that more such high-heat events will occur in future.
In Brazil’s Cerrado, aquifers are losing more water than they can replace
- A new monitoring model combining satellite images with artificial intelligence can identify variations in the volume of Brazilian aquifers.
- The Urucuia, one of the largest aquifers in the Cerrado biome, saw its water volume decrease by 31 cubic kilometers (7.43 cubic miles) over two decades; most of it is in western Bahia, where monoculture plantations are gaining ground.
- According to researchers, Brazil’s groundwaters—which cover 2.84 million square kilometers (1 million square miles) — remain “an unknown resource,” and few tools exist to monitor them.
Experts highlight importance of ‘prebunking’ to combat climate disinformation
- For journalists covering climate change and other complex issues, battling disinformation is a major challenge.
- Disinformation experts use a method called “prebunking” to reveal deceptive techniques and guard against manipulation; it’s a proactive approach, rooted in inoculation theory in psychology, which encourages critical thinking in the face of false information.
- However, the method faces cultural obstacles in some countries such as Bhutan; communication professionals say journalists and local communities should receive training so they are informed about climate science and other relevant subjects in order to fight disinformation.
Warming climate threatens to worsen air quality in already polluted Kathmandu
- In the period between winter and spring each year, Kathmandu faces severe air pollution that affects thousands of residents with health problems like burning eyes, respiratory discomfort, and even death.
- Local sources like vehicle emissions and construction dust, compounded by Kathmandu’s geography, are the main drivers of the pollution, and rising global temperatures threaten to worsen the situation.
- Changes in weather patterns, including reduced rainfall and prolonged dry periods are among the changes that could make air pollution an even more severe problem than it already is.
- Wildfires, both natural and human-induced, contribute significantly to air pollution in Kathmandu, especially during the transition period between weather systems, which could become longer due to rising temperatures.
Warming seas push India’s fishers into distant, and more dangerous, waters
- Many of India’s more than 4 million fishers are sailing beyond the country’s exclusive economic zone into the high seas in search of a better catch.
- Rising sea surface temperatures, overfishing near the shore, and the destruction of reefs have decimated nearshore fisheries, forcing India’s fishers farther out to sea where they face greater risk.
- A common danger they run is straying into the waters of another country, which can lead to their boats being seized and the crew being jailed or even killed.
- The Indian government has issued policies to protect and recover nearshore fish stocks, even as it encourages fishing in the high seas.
Annual ocean conference raises $11.3b in pledges for marine conservation
- The 9th Our Ocean Conference (OOC) took place in Athens from April 15-17.
- Government, NGO and philanthropic delegates made 469 new commitments worth more than $11.3 billion to help protect the oceans, which was lower than in previous years.
- While some conference hosts and attendees celebrated the many successes of the OOC, there was also a shared concern that decision-makers aren’t moving fast enough to secure a sustainable future for the global ocean.
Panama delays promised relocation of sinking island community
- The government of Panama continues to delay the process of relocating almost 1,300 Indigenous Guna inhabitants from an island experiencing rising sea levels due to climate change.
- The lack of space on the tiny Caribbean island of Gardi Sugdub means there’s no room to relocate, and a new site on the mainland for the community has been in the works since 2019.
- But plans for the relocation have been repeatedly delayed due to administrative issues, previous COVID-19 restrictions and poor budgeting, leaving residents skeptical that government promises will be upheld.
- Members of this fishing community have also expressed concern about the relocation site, which is a 30-minute walk from the coast, and about the design of the new homes, for which the government didn’t seek Guna input.
Hyundai ends aluminum deal with Adaro Minerals following K-pop protest
- The South Korean auto company Hyundai has ended its 2022 agreement for procuring aluminum for its electric vehicles from Adaro Minerals, which plans to build 2.2 gigawatts of coal-fired power plants to power its aluminum smelter.
- The decision follows campaigns coordinated by Kpop4Planet, a climate movement led by K-pop fans who protested Hyundai’s business with Adaro.
- Climate group Market Forces has estimated Adaro’s coal plants would emit 5.2 million metric tons of CO2 equivalent per year, and activists say Hyundai would be pushed further from reaching its goal of carbon neutrality by 2045.
- The campaign collected more than 11,000 petition signatures from K-pop fans in 68 countries.
Enviva bankruptcy fallout ripples through biomass industry, U.S. and EU
- In March, Enviva, the world’s largest woody biomass producer for industrial energy, declared bankruptcy. That cataclysmic collapse triggered a rush of political and economic maneuvering in the U.S. (a key wood pellet producing nation), and in Europe (a primary industrial biomass energy user in converted coal plants).
- While Enviva publicly claims it will survive the bankruptcy, a whistleblower in touch with sources inside the company says it will continue failing to meet its wood pellet contract obligations, and that its production facilities — plagued by chronic systemic manufacturing problems — will continue underperforming.
- Enviva and the forestry industry appear now to be lobbying the Biden administration, hoping to tap into millions in renewable energy credits under the Inflation Reduction Act — a move environmentalists are resisting. In March, federal officials made a fact-finding trip to an Enviva facility and local communities who say the firm is a major polluter.
- Meanwhile, some EU nations are scrambling to find new sources of wood pellets to meet their sustainable energy pledges under the Paris agreement. The UK’s Drax, an Enviva pellet user (and also a major pellet producer), is positioning itself to greatly increase its pellet production in the U.S. South and maybe benefit from IRA subsidies.
E-bikes could cut smog, energy use and congestion globally — but will they?
- The global market for e-bikes is surging. These bicycles, usually equipped with pedals and an electric motor assist, are popular with consumers and commuters and are becoming part of local business delivery systems. The trend could significantly reduce particulate pollution and smog, as well as cut carbon emissions in the transportation sector.
- But there are barriers. No international manufacturing standard yet exists for e-bikes. Also, transportation and charging infrastructure doesn’t adequately accommodate e-bikes, especially in the developing world where electric bicycles have the potential to replace super-polluting gas-powered scooters, motorcycles and pedicabs.
- Poorly made or improperly maintained e-bike batteries have developed a reputation for sometimes causing fires, exploding and even killing people, which has caused hesitation among consumers. While this safety problem is a real one, manufacturers and enthusiasts say the e-bike industry can effectively deal with it.
- Some governments are offering subsidies and tax incentives to e-bike buyers, while some companies are offering deals allowing customers to trade in gas two-wheelers for e-bikes. As sales and use grow, updated bike lane construction and safety rules setting permissible e-bike horsepower, speed and size will be required.
This year’s ranking of EV carmakers from most to least ‘clean’: Report
- A new scorecard by a coalition of labor and environmental civil society organizations ranked the top 18 automakers against 80 measures of what a clean car supply chain would look like.
- While car companies are increasingly embracing electric vehicles, a lack of tailpipe emissions is not enough for a car to be considered truly ‘clean,’ the authors say.
- From the steel, aluminum, tires, batteries and people affected along the supply chain, the mining and manufacturing of these metal-dense machines puts heavy burdens on landscapes, Indigenous peoples and workers.
- Ford and Mercedes-Benz lead the automotive world in working to clean up their supply chains, while Tesla jumped to third from last year’s ninth spot. East Asian firms fell behind as they lacked policies to address decarbonization in the production of steel and aluminum.
Rising temperatures threaten the tiny animals responsible for groundwater quality
- A new study compared temperatures inside 12 caves around the world with their respective surfaces, showing that average annual temperatures in underground systems tend to mirror those of the surface, but with far less variation.
- The researchers also found that while some caves follow outdoor temperatures with little or no delay, others have temperatures that are very asynchronous with the surface, being at their warmest when the world outside is at its coldest, and vice versa.
- Scientists also detected the existence of daily thermal cycles in the deepest sections of some caves, suggesting that such cycles might mark the circadian rhythms of cave-adapted organisms.
- The results indicate that underground fauna — with many species ill-adapted to handle large temperature variations — might be at threat due to climate change, and that their extinction might risk the water quality of aquifers worldwide.
U.S. natural gas expansion would surrender world to fatal warming, experts say
- The United States is planning a major expansion of its export infrastructure for liquified natural gas (LNG), a fossil fuel mostly containing methane. Public outcry in the U.S. over the risk to the global climate forced U.S. President Joe Biden to pause the LNG permitting process for reconsideration in January.
- However, the U.S. continues investing billions in new LNG infrastructure abroad. Scientists and climate activists around the globe are warning that LNG expansion renders U.S. climate commitments unreachable, locks in fossil fuel emissions for decades and could trigger catastrophic warming.
- LNG emits more than coal when exported due to massive leaks of methane into the atmosphere during oceanic transport, a preprint study has found. Another report estimates that emissions from planned U.S. LNG exports, if all 12 facilities are approved, would total 10% of the world’s current greenhouse gas emissions.
- Climate impacts around the world would be severe, scientists say. Drought in Europe, for example, is already leading to higher food and energy prices, creating conditions for poverty even in developed nations, while a tipping point in the Amazon Rainforest could lead to mass deaths due to extreme heat and humidity.
What principles should define natural climate solutions? A new study has some answers
- The increased popularity of natural climate solutions (NCS), which aim to protect and restore natural ecosystems to address climate change, has resulted in misunderstandings and confusion around what constitutes such a solution.
- Researchers distill five foundational principles of natural climate solutions and 15 operational principles to guide their implementation; among others, the principles include equity, emphasizing the need for practitioners to respect human rights and self-determination of Indigenous peoples.
- Researchers argue that natural climate solutions that adhere to these principles are durable and effective in tackling climate change in the long run, resulting in widespread adoption.
- While experts agree that the outlined principles reduce confusion and spur climate action, they call for tightening the definitions of some principles to strengthen the proposed framework.
Freeze on Russian collaboration disrupts urgently needed permafrost data flow
- Accelerating Arctic warming threatens to thaw more and more carbon-rich permafrost and release vast amounts of greenhouse gases into the Earth’s atmosphere, but scientists don’t know when such a tipping point event might occur.
- The potential for large and abrupt permafrost emissions adds urgency to better understanding the factors that could turn permafrost from a carbon sink into a carbon source.
- However, more than half of all Arctic permafrost lies under Russian soil, and a two-year freeze on collaborations between Russian scientists and the international scientific community — prompted by the Russian invasion of Ukraine on Feb. 24, 2022 — is disrupting data flows and hamstringing the polar research community.
- Despite an uncertain geopolitical landscape, scientists are determined to close the data gap with work-arounds such as pivoting to “proxy” field sites, ramping up remote sensing with AI, and mining archived data for new insights. But reintegrating Russian research with other Arctic research is a priority of the scientific community.
The new Arctic: Amid record heat, ecosystems morph and wildlife struggle
- Every species of animal and plant that lives or breeds in the Arctic is experiencing dramatic change. As the polar region warms, species endure extreme weather, shrinking and altered habitat, decreased food availability, and competition from invading southern species.
- A wide array of Arctic organisms that rely on sea ice to feed or breed during some or all of their life cycles are threatened by melt: Over the past 40 years, the Arctic Ocean has lost about 75% of its sea ice volume, as measured at the end of the summer melt season. This translates into a loss of sea ice extent and thickness by half on average.
- Researchers note that the rate of change is accelerating at sea and on land. While species can adapt over time, Arctic ecosystem alterations are too rapid for many animals to adapt, making it difficult to guess which species will prevail, which will perish, and where.
- The only thing that could limit future extinctions, researchers say, is to quickly stop burning fossil fuels, the main driver of climate change.
‘Healthy humans without a healthy planet is a logical fallacy’: Interview with Dr. Sakib Burza
- Brought up watching nature’s grandeur in Indian Kashmir, Dr. Sakib Burza’s early inspiration in medicine began at home before he went on to work with Indigenous and local communities in tropical forest regions.
- Having worked in communities responding to the impacts of droughts and climate shocks, he says improved planetary health is crucial for better human health, and that health problems are often the symptoms of climate change or environmental problems.
- At Health In Harmony, he leads medical projects with rainforest communities through the concept of radical listening and supporting their medical needs and livelihoods.
- In an interview with Mongabay, Dr. Burza lays out his argument for how and why the health of people and the planet are connected, and actions that can improve the state of both.
Freeing trees of their liana load can boost carbon sequestration in tropical forests
- Lianas are woody, vining plants, many of which thrive in areas where forest has been disturbed — often to the detriment of the trees they use to climb towards the sun.
- New research shows that liana cutting is a low-cost natural climate solution that can boost the amount of carbon absorbed by a tree.
- The study’s results indicate that freeing just five trees per hectare of their liana load could remove 800 million tons of C02 from the atmosphere over a 30 year period if applied across 250 million hectares of managed forest.
- Liana cutting is also seen as a way for foresters and conservationists to work together, improving both the forest’s power to sequester carbon and the quality of the timber that is being logged, as well as a way to generate income for local communities.
Ocean heating breaks record, again, with disastrous outcomes for the planet
- New research shows that ocean temperatures are hotter than ever in the modern era due to human-driven global warming.
- High ocean temperatures are placing a strain on marine life and biological processes while also increasing extreme weather events on land.
- The world is also seeing an escalation in the frequency and intensity of marine heat waves, events in which sea temperatures exceed a certain threshold for five days or more.
Hotter seas lead to coral bleaching along Colombia’s coast, 2023 expeditions find
- In the hottest months of 2023, sea temperatures rose above average for more than 12 weeks off Colombia’s Caribbean coast, leading to serious impacts on coral reefs.
- Expeditions in July by the NGO Corales de Paz revealed increased coral bleaching in monitored areas.
- The NGO found that 25% of the hard coral colonies sampled in Rincón del Mar and 28.5% in Punta Venado showed some signs of bleaching; off Varadero, the coral bleaching exceeded 40%.
Study: Burning wood pellets for energy endangers local communities’ health
- A new peer-reviewed study quantifies broadly for the first time the air pollution and public health impacts across the United States from both manufacturing wood pellets and burning them for energy.
- The study, said to be far more extensive than any research by the US Environmental Protection Agency, finds that U.S. biomass-burning facilities emit on average 2.8 times the amount of pollution of power plants that burn coal, oil or natural gas.
- Wood pellet manufacturers maintain that the harvest of forest wood for the purpose of making wood pellets to burn for energy remains a climate-friendly solution. But a host of studies undermine those claims.
- The Southern Environmental Law Center says the study provides new and rigorous science that could become a useful tool in arguing against the expansion of the wood pellet industry in the United States.
2023 fires increase fivefold in Indonesia amid El Niño
- Nearly 1 million hectares (2.47 million acres, an area 15 times the size of Jakarta) burned in Indonesia between January and October 2023, according to environment and forest ministry data; El Niño and burning for new plantations contributed to this.
- 2023 was the worst fire season since 2019, when that year’s El Niño brought a prolonged dry season and fires so severe, they sent billowing smoke across Malaysia and Singapore.
- In the absence of local jobs, some people burn abandoned farmlands and turn them into new plantations as a way to make a living and survive.
Reversing progress, Indonesia pulp & paper drives up deforestation rates again
- Reversing years of progress, deforestation caused by Indonesia’s pulp and paper industry is on the rise, increasing fivefold between 2017 and 2022, according to a new analysis.
- The increase in deforestation follows dramatic declines that occurred after major wood pulp and paper companies adopted zero-deforestation commitments due to public pressure.
- In addition to deforestation, the pulp and paper industry is linked to land and forest fires and peat subsidence, which contribute to the greenhouse gas emissions (GHG) that speed up global warming.
Detailed NASA analysis finds Earth and Amazon in deep climate trouble
- A NASA study analyzed the future action of six climate variables in all the world’s regions — air temperature, precipitation, relative humidity, short- and long wave solar radiation and wind speed — if Earth’s average temperature reaches 2° Celsius (3.6° Fahrenheit) above preindustrial levels, which could occur by 2040 if emissions keep rising at current rates.
- The authors used advanced statistical techniques to downscale climate models at a resolution eight times greater than most previous models. This allows for identification of climate variations on a daily basis across the world, something essential since climate impacts unfold gradually, rather than as upheavals.
- The study found that the Amazon will be the area with the greatest reduction in relative humidity. An analysis by the Brazilian space agency INPE showed that some parts of this rainforest biome have already reached maximum temperatures of more than 3°C (5.4°F) over 1960 levels.
- Regardless of warnings from science and Indigenous peoples of the existential threat posed by climate change, the world’s largest fossil fuel producers, largely with government consent, plan to further expand fossil fuel exploration, says a U.N. report. That’s despite a COP28 climate summit deal “transitioning away from fossil fuels.”
Earth on ‘devastating trajectory’ to global tipping points. But there’s hope.
- A new report on global tipping points warns of imminent serious disruptions in major Earth systems if global temperatures continue rising due to human-induced climate change.
- It suggests that current levels of warming will likely push five major Earth systems past their tipping points, and another three will follow if global temperatures exceed 1.5° Celsius (2.7° Fahrenheit) of warming above preindustrial levels.
- However, along with these dire warnings, the report also notes the launch of positive tipping points within society, such as the rollout of renewable energy technologies.
- Other reports also describe the urgency to enact positive change as humanity continues pumping carbon into the atmosphere, wreaking havoc on the environment.
Despite progress, small share of climate pledge went to Indigenous groups: report
- A report from funders of a $1.7 billion pledge to support Indigenous peoples and local communities’ land rights made at the 2021 U.N. climate conference found that 48% of the financing was distributed.
- The findings also show that only 2.1% of the funding went directly to Indigenous peoples and local communities, despite petitions to increase direct funding for their role in combating climate change and biodiversity loss.
- This is down from the 2.9% of direct funding that was disbursed in 2021.
- Both donors and representatives of Indigenous and community groups call for more direct funding to these organizations by reducing the obstacles they face, improving their capacity, and respecting traditional knowledge systems.
Carbon credit certifier Verra updates accounting method amid growing criticism
- The world’s largest carbon credit certifier, Verra, has overhauled its methods for calculating the climate impacts of REDD projects that aim to reduce deforestation.
- REDD stands for reducing emissions from deforestation and forest degradation.
- The emissions reductions from these projects can be sold on the voluntary carbon market to individuals and companies, which proponents say provides a vital stream of funding for forest conservation.
- The update changes the process for calculating deforestation baselines, which help determine how effective a project has been at reducing forest loss and keeping the carbon those trees contain out of the atmosphere.
Enviva, the world’s largest biomass energy company, is near collapse
- The forest biomass energy industry took a major hit this month, as Enviva, the world’s largest producer of wood pellets — burned in former coal power plants to make energy on an industrial scale — saw catastrophic third quarter losses. Enviva’s stock tanked, its CEO was replaced and the company seems near collapse.
- Founded in 2004, Enviva harvests forests in the U.S. Southeast, with its 10 plants key providers of wood pellets to large power plants in the EU, U.K., Japan and South Korea — nations that use a scientifically suspect carbon accounting loophole to count the burning of forest wood as a renewable resource.
- A former manager and whistleblower at Enviva told Mongabay in 2022 that the company’s green claims were fraudulent. Last week, he said that much of Enviva’s downfall is based on its cheaply built factories equipped with faulty machinery and on large-scale fiscal miscalculations regarding wood-procurement costs.
- How the firm’s downfall will impact the global biomass for energy market, and worldwide pellet supply, is unknown. European and Asian nations rely on Enviva pellets to supply their power plants and to meet climate change goals, with the burning of forests to make energy erroneously claimed as producing zero emissions.
Amazon deforestation has a regional, not just local impact: study
- A new study found that deforestation in the Amazon doesn’t just raise temperatures in the areas where the deforestation took place but rather throughout the entire region.
- Researchers analyzed satellite readings of surface temperatures at 3.7 million different data points across the Amazon where forest loss had occurred between 2001 and 2020.
- They found that localized deforestation had a strong impact on regional warming.
Deforestation continues in Kenya’s largest water capturing forest, satellites show
- New satellite data shows ongoing tree cover loss in Kenya’s largest water catchment, the Mau Forest, despite protection efforts.
- More than 19% of tree cover was lost between 2001 and 2022, mostly due to agriculture.
- Unclear boundaries and limited enforcement allow illegal logging and agricultural expansion to continue, degrading protected reserves.
- Conservationists argue stronger monitoring and enforcement is urgently needed to save Mau Forest and preserve its rich biodiversity and water resources.
Climate change threatens the North Atlantic’s currents, ecosystems and stability (analysis)
- The Atlantic Meridional Overturning Circulation (AMOC) is a vital component of the Earth’s global ocean circulation, and encompasses a network of currents within the Atlantic Ocean.
- Current research shows a possible slowing or stopping of the AMOC due to climate change, with direct and major impacts on marine ecosystems, weather variability, and food security in North America and Europe, and by extension the rest of the world.
- “A significant and sustained weakening of the AMOC has the potential to lead to its outright collapse, which would have far-reaching and mostly irreversible effects on marine and terrestrial ecosystems,” a new analysis explains.
- This post is an analysis. The views expressed are those of the author, not necessarily of Mongabay.
Record North Atlantic heat sees phytoplankton decline, fish shift to Arctic
- Scientists warn that record-high sea surface temperatures in the North Atlantic Ocean this year are having consequences for sea life.
- As marine heat waves there have worsened over the years, populations of phytoplankton, the base of the oceanic food chain, have declined in the Eastern North Atlantic.
- With experts predicting more heat anomalies to come, North Atlantic fish species are moving northward into the Arctic Ocean in search of cooler waters, creating competition risks with Arctic endemic species and possibly destabilizing the entire marine food web in the region.
- Lengthening and intensifying marine heat waves around the globe are becoming a major concern for scientists, who warn that the world will see even greater disruptions to ocean food chains and vital fisheries, unless fossil fuel burning is curtailed.
As oceans warm, marine heat waves push deep beneath the surface, study shows
- A new study found that the ocean experiences the most intense marine heat waves at a depth of between 50 and 250 meters (160 and 820 feet), where a large portion of the ocean’s biodiversity can be found.
- It also found that parts of the ocean between 250 and 2,000 m (6,600 ft) had less intense but longer marine heat waves, with a duration twice as long as at the surface.
- The intensity and duration of marine heat waves could have widespread effects on marine biodiversity, increasing the likelihood of species displacement and mortality, the study suggests.
On Jakarta’s vanishing shoreline, climate change seen abetting child marriages
- Marriage before the age of 18 is classified as a form of gender-based violence by the United Nations, but is commonly practiced in low-income communities to mitigate household economic pressures.
- On Jakarta’s northern coastline, child marriage is common in fishing communities responding to inflationary pressures and declining stocks of fish in near-shore waters.
- Janah, now 23, fears she lacks the agency to break a cycle that saw her married at the age of 16.
‘We don’t have much time’: Q&A with climate scientist Pierre Friedlingstein
- “It’s not going in the right direction yet,” Pierre Friedlingstein tells Mongabay of the effort to meet the Paris Agreement goals; a member of the IPCC and a climate professor, he says he’s mildly optimistic about the trend in global emissions.
- Friedlingstein says he’s hoping deforestation will go down in the coming years in Brazil, but he’s not sure that Indonesia, another major global carbon sink, is ready to go in the right direction at the moment.
- He says the COVID-19 pandemic showed that climate is still “not on the top of the list” of government priorities, given that all nations sought to boost economic growth after lockdowns, despite the carbon emissions they incurred.
U.N. ‘stocktake’ calls for fossil fuel phaseout to minimize temperature rise
- The U.N. climate change agency published a new report Sept. 8 confirming that while there has been progress on climate change mitigation since the landmark Paris Agreement in 2015, more needs to be done to limit the global rise in temperatures at 1.5°C (2.7°F) above pre-industrial levels.
- The report is an element of the global stocktake, a Paris Agreement-prescribed inventory of progress toward climate-related goals.
- The authors of the report called for phasing out fossil fuels and ramping up renewable energy.
- The global stocktake process will conclude at the U.N. climate conference (COP28) beginning Nov. 30 in Dubai, United Arab Emirates.
Sensing tech used in oil pipelines can also track Arctic sea ice, study shows
- Scientists have used undersea fiber-optic cables in the Arctic to remotely track the presence and extent of sea ice.
- Sea ice is usually monitored with the help of satellites; however, the lack of high-resolution images and the low frequency of data collection makes it difficult to do in-depth analysis.
- Using a method commonly employed to monitor oil pipelines and highways, the scientists looked for changes in signals sent down a fiber-optic cable in the Beaufort Sea that would indicate the presence of sea ice.
- While promising, the method can’t yet be used to measure the thickness of sea ice or to determine how far the ice extends to either side of the cable.
Study finds old pear trees make for surprisingly rich reef habitats
- In a new study, researchers used old pear trees to create artificial reefs and settled them in the Wadden Sea in the Netherlands to see what kinds of marine biodiversity aggregated on or around them.
- They found that the tree reefs attracted a surprising amount of biodiversity over a short period of time, including sessile organisms like barnacles and mobile species like fish and crabs.
- The authors say tree reefs can be replicated in other parts of the world, mainly temperate regions.
Study: Tricky balancing act between EV scale-up and mining battery metals
- A recent study finds rapidly switching to electric vehicles could significantly cut emissions but also increase demand for critical battery metals like lithium and nickel.
- Mining metals like lithium has major environmental impacts including deforestation, high water use, and toxic waste.
- Electrifying heavy-duty vehicles requires substantially more critical metals than other EVs and could account for 62% of critical metal demand in coming decades despite making up just 4-11% of vehicles.
- The researchers recommend policies to support recycling, circular economies, alternative battery chemistries, and coordinated action to balance environmental and material needs.
A tale of two biomes as deforestation surges in Cerrado but wanes in Amazon
- Brazil has managed to bring down spiraling rates of deforestation in the Amazon Rainforest in the first half of this year, but the neighboring Cerrado savanna has seen a wave of environmental destruction during the same period.
- The country’s second largest biome, the Cerrado is seeing its highest deforestation figure since 2018; satellite data show 3,281 hectares (8,107 acres) per day have been cleared since the start of the year through Aug. 4.
- The leading causes of the rising deforestation rates in the Cerrado are a disparity in conservation efforts across Brazil’s biomes, an unsustainable economic model that prioritizes monocultures, and escalating levels of illegal native vegetation clearing.
- Given the importance of the Cerrado to replenish watersheds across the continent, its destruction would affect not just Brazil but South America too, experts warn, adding that the region’s water, food and energy security are at stake.
Beach heat: Study shows increasing temperature extremes on Brazil’s coast
- By analyzing temperature patterns at five points along the Brazilian coast over the last 40 years, scientists confirmed the impacts of global warming on the country: hotter summers, more heat waves and greater thermal amplitude throughout the day.
- On the coast of Espírito Santo state, the frequency of daily occurrences of extreme temperatures and heat waves increased by 188% during the period studied; Rio Grande do Sul saw an increase of 100% and São Paulo, 84%.
- Such climate extremes impact the health of people, plants and animals directly and indirectly, including changes in viral cycles.
EVs offer climate hope, but total auto supply chain revamp is vital
- Internal combustion engine vehicles (ICE) and electric vehicles (EV) both have supply chains that generate significant environmental impacts. Experts argue that circular economy principles — based on reducing, reusing and recycling materials — are key to increasing EV sustainability. But the auto industry has far to go to get there.
- Circularity is deemed particularly important for EVs, which are tipped as a vital climate solution and as the future of light transport across the globe. But their introduction globally is dependent on soaring material resourcing and production, all coming with “embedded emissions,” pollution and other impacts.
- At present, circularity is low in the auto industry, but experts see great potential, particularly for EV batteries. They argue for changes all along the supply chain to reduce material use and encourage advanced recycling.
- Others emphasize a holistic approach to land transport that reduces demand for automobiles in favor of public transportation. Circular economy solutions need to be achieved quickly in the transport sector if emissions are to be cut enough to help curb climate change and reduce pollution and other environmental ills.
Internal combustion vs. EVs: Learning from the past to boost sustainability
- Sales of electric vehicles are gathering pace, with numbers taking to the road steadily increasing in the U.S., Europe, and China; though that rollout is lagging far behind in emerging economies, especially in the Global South. That’s an issue that will need to be addressed if the world is to maximize transportation carbon cuts.
- EVs clearly outperform internal combustion engines (ICEs) in their vehicle carbon emissions. But assessments must be made across the whole life cycle of both types of vehicles to create true comparisons of environmental impacts and learn from them. EVs, for example, require lithium, the mining of which seriously pollutes.
- Even the amount of emissions produced by EVs needs to be carefully evaluated. While the cars themselves are clean, total emissions vary greatly depending on how the electricity to run them is produced (if the electrical grid is powered by coal, oil or gas, that’s very different than energy coming from wind and solar).
- For EVs to achieve their full sustainability potential, every aspect of automotive production needs to be assessed not only for environmental impacts, but for their effects on society, livelihoods and more. The use of a circular economy blueprint for creating clean EV supply chains will be assessed in part two of this story.
Indonesia’s coal burning hits record high — and ‘green’ nickel is largely why
- Indonesia burned 33% more coal in 2022 than the year before, contributing to a 20% increase in the country’s carbon emissions from fossil fuels, an analysis of official data shows.
- This will likely catapult Indonesia to become the world’s sixth-highest fossil CO2 emitter, behind Japan, according to the analysis.
- This rise in coal burning aligns with efforts to boost economic recovery following the COVID-19 pandemic, including the slate of new coal-fired power plants that recently came online as well as the expansion of the nickel industry.
- Industrial parks that are home to smelters processing nickel and other metals consume 15% of the country’s coal power output.
Microbes play leading role in soil carbon capture, study shows
- Soil is a significant carbon reservoir, storing more carbon than all plants, animals and the atmosphere combined, making it crucial for addressing the climate crisis.
- Microbes, such as bacteria and fungi, are the primary drivers of carbon storage in soil, surpassing other soil processes by a factor of four, according to a new study in Nature.
- The efficiency of microbial metabolism plays a vital role in determining the amount of organic carbon stored in soils worldwide, according to the research, which also calls for improved soil carbon models for effective policies and climate solutions.
- Enhancing microbial efficiency can lead to increased carbon storage in soils, but further research is needed to understand how to achieve this.
New data show 10% increase in primary tropical forest loss in 2022
- Globally, the tropics lost 4.1 million hectares (10.1 million acres) of primary forest in 2022, 10% more than in 2021.
- These losses occurred despite the pledges of 145 countries at COP26 in 2021 to increase efforts to reduce deforestation and halt it by 2030; the new data, from the University of Maryland, puts the world far off track for meeting the goal of zero deforestation.
- According to Frances Seymour of World Resources Institute, there is an urgent need to increase financing for protecting and restoring forests.
Mycorrhizal fungi hold CO2 equivalent to a third of global fossil fuel emissions
- A recent study estimates that more than 13 billion metric tons of CO2 from terrestrial plants are passed on to mycorrhizal fungi each year, equivalent to about 36% of global fossil fuel emissions.
- The study highlights the overlooked role of mycorrhizal fungi in storing and transporting carbon underground through their extensive fungal networks
- Researchers analyzed nearly 200 data sets from various studies that traced carbon flow and found that plants allocate between 1% and 13% of their carbon to mycorrhizal fungi.
- Understanding the role of mycorrhizal fungi is essential for conservation and restoration efforts, as soil degradation and the disruption of soil communities pose significant threats to ecosystems and plant productivity.
Antarctic warming alters atmosphere, ice shelves, ocean & animals
- The world’s latest record-high temperatures are increasingly putting Antarctica’s role in regulating global climate and ocean currents at risk. But so far, most signs indicate that the continent has not yet reached a point of no return. A rapid reduction in fossil fuel extraction and carbon emissions could still prevent the worst outcomes.
- Increased persistence of the Antarctic ozone hole over the past three years could be an indication of climate change, as it cools the south polar stratosphere, though high variability in this phenomenon and its complexity make causality difficult to prove.
- As global warming continues to melt Antarctica’s edges, a modeling study shows that fresh water going into the ocean could result in the next three decades in a more than 40% slowdown in the currents carrying heat and nutrients northward, essential to sustain ocean life as we know it. If ice shelves melt, allowing Antarctica’s ice sheets to flow to the sea, sea level rise will escalate.
- The latest discovery of a new colony of emperor penguins (Aptenodytes forsteri) in a marginal habitat of the Antarctic is good news, but also bad news, as it further highlights the vulnerability of the species as Antarctic ice masses destabilize — volatility that threatens their survival.
U.N. climate chief calls for end to fossil fuels as talks head to Dubai
- International climate talks began in Bonn, Germany, on June 5.
- A key part of the discussion will be the global stocktake, assessing progress toward the emissions cuts pledged by nations as part of the 2015 Paris climate agreement.
- Discussions will work to provide the technical details of the stocktake, but the consensus is that the world is not on track to cut emissions by 50% by 2030, which scientists say is key to keeping the global temperature rise below 1.5°C (2.7°F) over pre-industrial levels.
- The talks are a precursor to COP28, the annual U.N. climate conference, scheduled to begin Nov. 30 in Dubai, United Arab Emirates, which is a major oil- and gas-producing nation.
Financial downturn at Enviva could mean trouble for biomass energy
- Enviva harvests trees to manufacture millions of tons of wood pellets annually in the U.S. Southeast to supply the biomass energy demands of nations in the EU, U.K., Japan and South Korea. But a host of operational, legal and public relations problems have led to greater-than-expected revenue losses and a drastic fall in stock price.
- These concerns (some of which Mongabay has reported on in the past) raise questions as to whether Enviva can double its projected pellet production from 6 million metric tons annually today to 13 million metric tons by 2027 to meet its contract obligations. Enviva says its problems pose only short-term setbacks.
- While it isn’t possible to connect Enviva’s stock decline, or the company’s downgrading by a top credit ratings agency, with any specific cause, some analysts say that investors may be getting educated as to the financial risk they could face if the EU or other large-scale biomass users eliminate their subsidies to the industry.
- “The financial risk is there, maybe not today, but in the future, where countries may say, ‘This massive [biomass carbon accounting] loophole is making the climate crisis worse. Let’s close it.’ When that happens, Enviva and all other pellet manufacturers are out of business,” and investors would suffer, according to one industry expert.
As tourism booms in India’s Western Ghats, habitat loss pushes endangered frogs to the edge
- India’s Western Ghats, a global biodiversity hotspot, is home to many endemic and endangered species of amphibians, some of which are new to science and others suspected of lying in wait of discovery.
- Deforestation due to infrastructure and plantation expansion in the southern Western Ghats threaten the region’s amphibian species, many of which have highly restricted habitats.
- Adding to their woes is an increased risk of landslides in parts of Kerala due to erratic, heavy monsoon rains and erosion due to loss of forest.
- To save them, experts are calling for a systematic taxonomic survey of amphibians in the region and for legal protection of endangered species.
Overlooked and underfoot, mosses play a mighty role for climate and soil
- Mosses cover a China-size area of the globe and have a significant impact on ecosystems and climate change, according to a new study.
- Researchers conducted the most comprehensive global field study of mosses to date to quantify how soil moss influences soil and ecosystem services in different environments on all seven continents.
- Soil mosses can potentially add 6.43 billion metric tons of carbon to the soil globally, an amount equivalent to the annual emissions of 2.68 billion cars.
- Moss-covered soil offers several other benefits, including cycling of essential nutrients, facilitating faster decomposition, and reducing harmful plant pathogens.
In Indonesia, clouds form over East Java’s promising band of avocado growers
- Global avocado production is rising to meet demand from increasingly health-conscious consumers.
- South and Central American producers remain the world’s largest, but production in Indonesia is rising quickly.
- Farmers have found new ways to increase value, but research shows rising temperatures and increased rainfall threaten to undermine productivity.
As Exxon bows out, industry takes step toward sustainable algae biofuels
- In February, ExxonMobil gave up its decade-long attempt to cultivate algae as a profitable and scalable feedstock for biofuel — a liquid alternative energy source needed to power aviation, ocean-going ships, and long-distance trucking, while also combating climate change.
- That corporate setback was offset by advances elsewhere in the industry: California-based algae biofuel company Viridos, which lost ExxonMobil as its partner, raised $25 million this year as it gained United Airlines, Chevron and Breakthrough Energy Ventures as investors to keep its algae project moving toward commercialization.
- Also, this year, the U.S. Department of Energy Bioenergy Technologies Office (BETO) funded four major algae biofuel and biomass projects to chart scalable production processes and achieve low-carbon intensity efficiency.
- Several of these algae initiatives are now moving from basic R&D into pilot programs, with scaled-up commercial production possibly just a few years away, according to industry experts. Environmentalists are concerned about future land, energy and fertilizer impacts during production, though say it is too early to assess potential commercialization effects.
How will climate change affect Latin America? Scientists respond to IPCC report
- Mongabay Latam spoke with scientists who contributed to the latest Intergovernmental Panel on Climate Change (IPCC) report about the effects in Latin America, opportunities for mitigation and adaptation and the contributions of Native cultures.
- IPCC released the latest report in March as a synthesis summarizing the six previous reports it has issued on the situation of the planet since 2015.
- The new scientific report warns once again of increased global warming, but also mentions that solutions exist with the help of technology and local communities.
Study attempts to foresee the future of Amazonian mammals if the rainforest turns into savanna
- What could become of the some 300 species of mammals living in Amazonia if deforestation and global warming lead to the savannization of the rainforest?
- Researchers analyzed images from 400 photo traps placed in four natural enclaves of the Cerrado biome in southern Amazonia to find some answers; analysis of the photos showed that, when given the choice between preserved Amazon Rainforest and preserved Cerrado, most species chose the rainforest.
- Another study analyzed rainforests around the world, finding that savannization may happen sooner than expected; in Amazonia, this occurrence will mean reduced population and range for mammals like jaguars, tapirs and deer.
Southern atmospheric rivers drive irreversible melting of Arctic sea ice: Study
- Arctic sea ice extent has reached its winter maximum extent for 2023 at 14.62 million sq. km., the fifth lowest on record. Combined with this year’s unprecedentedly small Antarctic sea ice summer minimum extent, global sea ice coverage reached a record low in January.
- Arctic sea ice is not only receding, but also seriously thinning. New research has found that a huge melt in 2007 and associated ocean warming kicked off a “regime shift” to thinner, younger, more mobile and transient ice that may be “irreversible.”
- A big reason why Arctic sea ice is declining even in the frigid polar winter is that atmospheric rivers, which carry warmth and rainfall like the deluges seen in California recently, are surging up from the south and penetrating the Arctic more often.
Sea level rise looms, even for the best-prepared country on Earth
- The Netherlands, a low-lying European country with more than a quarter of its land below sea level, has been going to great lengths to protect itself from the impacts of climate change, including sea level rise and extreme weather events like heavy rain.
- But even for the Netherlands, a country with the wealth and experience to address these issues, the future remains uncertain, mainly because a range of possible scenarios could play out after 2050.
- According to the Intergovernmental Panel on Climate Change, a low-emissions scenario for the greenhouse gases that amplify global warming could elevate sea levels about half a meter (1.6 feet) above present levels by 2100; a higher-emissions scenario could lead to a 2-m (6.6-ft) rise by 2100 and a 5-m (16.4-ft) rise by 2150.
- Experts say that most other countries need to take the threat of sea level rise more seriously, and that engineering challenges, a lack of awareness and education, sociocultural concerns, and financial constraints are hampering their preparation.
Sagarmatha microbes may survive harsh conditions for decades
- Researchers have found microbes on Mount Everest that can survive harsh winds and conditions at some of the world’s highest elevations.
- The research comes at a time when scientists say melting glaciers and permafrost could reawaken viruses and bacteria as the climate warms.
- However, the microbes found on Mount Everest, which were possibly transported by humans through their coughing and sneezing, are unlikely to grow and reproduce, said University of Colorado Boulder scientist Steve Schmidt, a co-author of a new study on the team’s findings.
IPCC warns of ‘last chance’ to limit climate change via drastic emissions cuts
- The United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its sixth “synthesis” report March 20, after its approval by world leaders at a weeklong meeting in Switzerland.
- The report’s authors conclude that immediate reductions in carbon emissions are necessary to limit the rise in the global temperature to 1.5° Celsius (2.7° Fahrenheit) above pre-industrial levels.
- Scientists, activists and observers are calling for an end to fossil fuel use.
Peatland restoration in temperate nations could be carbon storage bonanza
- Much maligned and undervalued over the centuries, temperate peatlands have seen a lot damage in that time — drained for agriculture, planted with trees, mined for horticulture and fuel. But in an age of escalating climate change, people are now turning to restoration.
- As potent carbon sequesters, peatlands have only recently been given new attention, with active restoration taking place in many nations around the world. This story focuses on groundbreaking temperate peatland restoration efforts in the U.S. Southeast, Scotland and Canada.
- Every temperate peatland is different, making each restoration project unique, but the goal is almost always the same: restore the natural hydrology of the peatland so it can maximize carbon storage and native biodiversity, and improve its resilience in the face of climate change and increasingly common fires in a warming world.
‘Not a good sign’: Study shows Greenland temperatures at 1,000-year high
- New research shows that north-central Greenland experienced the highest temperatures between 2001 and 2011 over a 1,000-year period.
- Scientists came to this conclusion after reconstructing climate conditions over the last millennium by analyzing ice cores from the Greenland ice sheet.
- This study can provide a foundation for future studies on ice melt and sea level rise, the authors say.
An El Niño is forecast for 2023. How much coral will bleach this time?
- Forecasts suggest that an El Niño climate pattern could begin later this year, raising sea temperatures at a time when global temperatures are already higher than ever due to human-driven climate change.
- If an El Niño develops and it becomes a moderate to severe event, it could raise global temperatures by more than 1.5°C (2.7°F) above pre-industrial levels, the threshold set by the Paris Agreement.
- An El Niño would generate many impacts on both terrestrial and marine ecosystems, including the potential for droughts, fires, increased precipitation, coral bleaching, invasions of predatory marine species like crown-of-thorns starfish, disruptions to marine food chains, and kelp forest die-offs.
Temperature extremes, plus ecological marginalization, raise species risk: Studies
- In a business-as-usual carbon emissions scenario — humanity’s current trajectory — two in five land vertebrates could be exposed to temperatures equal to, or exceeding, the hottest temperatures of the past decades across at least half of their range by 2099. If warming could be kept well below 2°C (3.6°F), that number drops to 6%, according to a new study.
- More than one in eight mammal species have already lost part of their former geographical range. In many cases, this means those species no longer have access to some (or sometimes any) of their core habitat, making it much more difficult to survive in a warming world.
- When animal populations continue to decline in an area even after it has been protected, one possible explanation may be that the conserved habitat is marginal compared to that found in the species’ historical range.
- In the light of recent pledges to protect 30% of the planet’s surface, it is important to prioritize the right areas. The focus should be on conserving core habitat — which is often highly productive and already intensively used by humans — while respecting the rights and needs of Indigenous people, many of whom have also been pushed to the margins.
The EU banned Russian wood pellet imports; South Korea took them all
- In July 2022, the European Union responded to the war in Ukraine by banning the import of Russian woody biomass used to make energy. At roughly the same time, South Korea drastically upped its Russian woody biomass imports, becoming the sole official importer of Russian wood pellets for industrial energy use.
- The EU has reportedly replaced its Russian supplies of woody biomass by importing wood pellets from the U.S. and Eastern Europe. But others say that trade data and paper trails indicate a violation of the EU ban, with laundered Russian wood pellets possibly flowing through Turkey, Kazakhstan and Kyrgyzstan to multiple EU nations.
- EU pellet imports from Turkey grew from 2,200 tons monthly last spring to 16,000 tons in September. Imports from Kazakhstan and Kyrgyzstan reportedly rose too, even though neither has a forest industry. A large body of scientific evidence shows that woody biomass adds significantly to climate change and biodiversity loss.
- Enviva, the world’s largest woody biomass producer, which operates chiefly in the Southeast U.S., may be the big winner in the Russian biomass ban. Since the war began, Enviva has upped EU shipments, and also announced a 10-year contract with an unnamed European customer to deliver 800,000 metric tons of pellets annually by 2027.
Top mangrove news of 2022
- Mangroves are unique forests adapted to live along the coasts in mostly tropical and subtropical areas of the world.
- Mangroves are in danger as they are cleared to make room for farms, mines, and other human developments.
- Mangroves provide a bevy of important ecosystem services such as flood and erosion control and greenhouse gas storage, and they provide habitat for many species.
- Below are some of the most notable mangrove news items of 2022.
Hunting for future-proof marine plants in the acidic waters bathing a volcano
- The naturally acidic seawater near an underwater volcano in Italy mimic pH levels that according to worst-case climate projections will be common by the end of the century and beyond.
- Scientists are studying local seagrass and seaweed responses to the acidic conditions.
- One question is whether they could be used for restoration purposes in other places that may become more acidic in a not-so-distant future.
- Even so, some researchers point out that these carbon-sequestering marine plants face more immediate challenges from pollution, habitat degradation and warming waters that need addressing for restoration to succeed.
The Netherlands to stop paying subsidies to ‘untruthful’ biomass firms
- On December 5, 2022, Mongabay featured a story by journalist Justin Catanoso in which the first ever biomass industry insider came forward as a whistleblower and discredited the green sustainability claims made by Enviva — the world’s largest maker of wood pellets for energy.
- On December 15, citing that article and recent scientific evidence that Enviva contributes to deforestation in the U.S. Southeast, The Netherlands decided it will stop paying subsidies to any biomass company found to be untruthful in its wood pellet production methods. The Netherlands currently offers sizable subsidies to Enviva.
- Precisely how The Netherlands decision will impact biomass subsidies in the long run is unclear. Nor is it known how this decision may impact the EU’s Sustainable Biomass Program (SBP) certification process, which critics say is inherently weak and unreliable.
- Also in December, Australia became the first major nation to reverse its designation of forest biomass as a renewable energy source, raising questions about how parties to the UN Paris agreement can support opposing renewable energy policies, especially regarding biomass — a problem for COP28 negotiators to resolve in 2023.
Australia rejects forest biomass in first blow to wood pellet industry
- On December 15, Australia became the first major economy worldwide to reverse itself on its renewable classification for woody biomass burned to make energy. Under the nation’s new policy, wood harvested from native forests and burned to produce energy cannot be classified as a renewable energy source.
- That decision comes as the U.S., Canada, Eastern Europe, Vietnam and other forest nations continue gearing up to harvest their woodlands to make massive amounts of wood pellets, in order to supply biomass-fired power plants in the UK, EU, Japan, South Korea and elsewhere.
- In the EU, forest advocates continue with last-ditch lobbying efforts to have woody biomass stripped of its renewable energy designation, and end the ongoing practice of providing large subsidies to the biomass industry for wood pellets.
- Science has found that biomass burning releases more carbon dioxide emissions per unit of energy produced than coal. Australia’s decision, and the EU’s continued commitment to biomass, creates a conundrum for policymakers: How can major economies have different definitions of renewable energy when it comes to biomass?
In Sierra Leone’s fishing villages, a reality check for climate aid
- In April, Mongabay’s Ashoka Mukpo visited the Sherbro estuary, a sprawling riverine ecosystem of mangroves and coastal fishing villages on the Sierra Leonean coastline.
- Like other coastal areas in West Africa, the Sherbro estuary is already suffering the impacts of climate change, including flooding and higher temperatures.
- Between 2016 and 2021, USAID financed mangrove replanting and the construction of makeshift seawalls in villages here as part of a coastal climate resilience aid project.
- The project’s struggles here are an example of the difficulties that climate aid efforts can face when they meet the economic and social needs of people in vulnerable areas.
As EU finalizes renewable energy plan, forest advocates condemn biomass
- The EU hopes to finalize its revised Renewable Energy Directive (RED) soon, even as forest advocates urge last minute changes to significantly cut the use of woody biomass for energy and make deep reductions in EU subsidies to the wood pellet industry.
- Forest advocates are citing a new commentary published in Nature that argues that the EU’s continued expansive commitment to burning forest biomass for energy will endanger forests in the EU, the U.S. and elsewhere — resulting in a major loss in global carbon storage and biodiversity.
- Changing RED to meet forest advocate recommendations seems unlikely at this point, with some policymakers arguing that woody biomass use is the only way the EU can achieve its 2030 coal reduction target. The woody biomass industry is pressing for sustained biomass use and for continued subsidies.
- Russia’s threat of reducing or cutting off its supply of natural gas to the EU this winter is also at issue. In the EU today, 60% of energy classified as renewable comes from burning biomass. If RED is approved as drafted, bioenergy use is projected to double between 2015 and 2050, according to the just published Nature commentary.
Whistleblower: Enviva claim of ‘being good for the planet… all nonsense’
- Enviva is the largest maker of wood pellets burned for energy in the world. The company has, from its inception, touted its green credentials.
- It says it doesn’t use big, whole trees, but only uses wood waste, “tops, limbs, thinnings, and/or low-value smaller trees” in the production of woody biomass burned in former coal power plants in the U.K., EU and Asia. It says it only sources wood from areas where trees will be regrown, and that it doesn’t contribute to deforestation.
- However, in first-ever interviews with a whistleblower who worked within Enviva plant management, Mongabay contributor Justin Catanoso has been told that all of these Enviva claims are false. In addition, a major recent scientific study finds that Enviva is contributing to deforestation in the U.S. Southeast.
- Statements by the whistleblower have been confirmed by Mongabay’s own observations at a November 2022 forest clear-cut in North Carolina, and by NGO photo documentation. These findings are especially important now, as the EU considers the future of forest biomass burning as a “sustainable” form of renewable energy.
Blue jeans: An iconic fashion item that’s costing the planet dearly
- The production of blue jeans, one of the most popular apparel items ever, has for decades left behind a trail of heavy consumption, diminishing Earth’s water and energy resources, causing pollution, and contributing to climate change. The harm done by the fashion industry has intensified, not diminished, in recent years.
- The making of jeans is water intensive, yet much of the world’s cotton crop is grown in semiarid regions requiring irrigation and pesticide use. As climate change intensifies, irrigation-dependent cotton cultivation and ecological catastrophe are on a collision course, with the Aral Sea’s ecological death a prime example and warning.
- While some major fashion companies have made sustainability pledges, and taken some steps to produce greener blue jeans, the industry has yet to make significant strides toward sustainability, with organic cotton, for example, still only 1% of the business.
- A few fashion companies are changing their operations to be more sustainable and investing in technology to reduce the socioenvironmental impacts of jeans production. But much more remains to be done.
Small share of land rights pledge went to Indigenous groups: Progress report
- A report from funders of a $1.7 billion pledge to support Indigenous and community forest tenure made at the 2021 U.N. climate conference found that 19% of the financing has been distributed.
- The findings from 2022 also show that only 7% of the funding went directly to Indigenous and community organizations, despite the protection they provide to forests and other ecosystems. (A subsequent analysis in 2023 revised this figure downward to 2.9%.)
- Both donors and representatives of Indigenous and community groups are calling for more direct funding to these organizations by reducing the barriers they face, improving communication and building capacity.
Arctic sea ice loss to increase strong El Niño events linked to extreme weather: Study
- The frequency of strong El Niño events could increase by 35% by the end of the century as Arctic sea ice begins to melt out completely in the summer, according to a recent modeling study. El Niños — buildups of especially warm water in the eastern Pacific off of Peru — often trigger ‘devastating’ droughts, floods and cyclones around the globe.
- The findings provide more evidence that Arctic warming is affecting weather in other parts of the world — not only in the mid-latitudes, but as far away as the tropics.
- Other recent studies have found that sea ice loss is causing rapid acidification of the Arctic Ocean and more extreme precipitation and flooding in Svalbard, a Norwegian archipelago located between mainland Norway and the North Pole.
A ‘super reef’ recovery raises hopes — but also questions about its resilience
- Experts documented the substantial recovery of coral reefs around the southern Line Islands in the central Pacific after the area was hit by a large-scale coral bleaching event in 2015 and 2016.
- Many factors may have contributed to the reef’s recovery, including the fact that the reef is seemingly untouched by human activity, which helped maintain a healthy and resilient ecosystem.
- But other experts question whether this reef would be able to recover after more frequent bleaching events, which are predicted to increase as global temperatures continue to rise.
Mangrove restorers in Haiti bet on resilience amid rising violence
- Haiti is one of the most deforested countries in the world today, with its mangroves in particular now dotting just 30% of its coastline, much of it in thin, fragmented pockets.
- The main threat to the mangroves is the cutting of the trees to produce charcoal, an important fuel for cooking in a country where only a quarter of the population has access to electricity.
- Several mangrove restoration projects have been initiated over the years, and many abandoned due to waning community interest, natural disasters, or poor planning.
- More recently, rising rates of violence have prevented restoration teams from going to the field and coordinating with one another, but some are hopeful that communities remain receptive to mangrove restoration despite all the other hardships they’re experiencing.
Greenland’s Indigenous population favors extracting sand from melting ice sheet
- In 2022, the Greenland ice sheet experienced net ice loss for the 26th year in a row. But that loss is producing a potentially valuable resource: sand, which the melting ice sheet is depositing on the coast.
- Together, sand and gravel are one of the most traded commodities in the world, and a study by researchers at McGill University found that the majority of Greenlanders, including Indigenous people, supported extracting sand for export.
- But Greenlanders—who have staunchly opposed some mining projects in the past—say this activity needs to be done with adequate environmental protection and consultation of Greenland’s predominantly Indigenous population.
- The environmental consequences are uncertain but could include impacts from sucking sand off the substrate and increasing shipping traffic.
2022: Another consequential year for the melting Arctic
- Arctic sea ice extent shrank to its summertime minimum this week — tied with 2017 and 2018 for the 10th lowest ever recorded. However, the last 16 consecutive years have seen the least ice extent since the satellite record began. Polar sea ice extent, thickness and volume all continue trending steeply downward.
- Arctic air temperatures were high this summer, with parts of the region seeing unprecedented heating. Greenland saw air temperatures up to 36° F. above normal in September. Canada’s Northwest Territories saw record highs, hitting the 90s in July. Sea temperatures also remained very high in many parts of the Arctic Ocean.
- Scientists continue to be concerned as climate change warms the far North nearly four times faster than the rest of the planet, sparking concern over how polar warming may be impacting the atmospheric jet stream, intensifying disastrous extreme weather events worldwide, including heat waves, droughts and storms.
- While a mostly ice-free Arctic could occur as early as 2040, scientists emphasize that it needn’t happen. If humanity chooses to act now to drastically reduce greenhouse gas emissions, downward sea ice extent and volume trends could potentially be reversed.
EU votes to keep woody biomass as renewable energy, ignores climate risk
- Despite growing public opposition, the European Parliament voted this week not to declassify woody biomass as renewable energy. The forest biomass industry quickly declared victory, while supporters of native forests announced their plan to continue the fight — even in court.
- The EU likely renewed its commitment to burning wood as a source of energy largely to help meet its target of cutting EU carbon emissions by 55% by 2030, something it likely couldn’t achieve without woody biomass (which a carbon accounting loophole counts as carbon neutral, equivalent to wind and solar power).
- Scientific evidence shows that burning wood pellets is a major source of carbon at the smokestack. The European Union also likely continued its embrace of biomass this week as it looks down the barrel of Russian threats to cut off natural gas supplies this winter over the EU’s opposition to Russia’s invasion of Ukraine.
- While the EU decision maintains that whole trees won’t be subsidized for burning, that natural forests will be protected, and that there will be limits to logging old growth and primary forests, these provisions include legal loopholes and were not backed with monitoring or enforcement commitments. No dates were set for biomass burning phase down.
‘Mind-blowing’ marine heat waves put Mediterranean ecosystems at grave risk
- A recent study reveals the widespread effects of climate change-driven marine heat waves on the ecological communities of the Mediterranean Sea.
- Rises in sea surface temperatures as high as 5° Celsius (9° Fahrenheit) above normal have caused die-offs in 50 different taxonomic groups of animals from around the Mediterranean Basin.
- These far-reaching impacts of the warming sea could devastate the fisheries on which many of the Mediterranean region’s 400 million people rely.
- Researchers advocate bolstering and expanding marine protected areas. Although they can’t hold back the warmer waters that have proven deadly to the sea’s rich biodiversity, these sanctuaries can help ensure that these species don’t have to cope simultaneously with other pressures, such as overfishing or pollution.
Warming has set off ‘dangerous’ tipping points. More will fall with the heat
- A new study warns that multiple tipping points will be triggered if global warming exceeds 1.5°C (2.7°F) above pre-industrial levels.
- The researchers say humanity is already at risk of passing five tipping points, including the melting of the Greenland and West Antarctica ice sheets and the mass die-off of coral reefs, at the current levels of warming, and that the risk will increase with each 0.1°C (0.18°F) of warming.
- While many nations have committed to the 2015 Paris Agreement, which stipulates that warming should be limited to 1.5°C, it’s unclear whether this goal will be achieved.
The Western Indian Ocean lost 4% of its mangroves in 24 years, report finds
- Analysis presented in a new report finds the Western Indian Ocean (WIO) region lost around 4% its mangrove forests between 1996 and 2020.
- The WIO region includes the coastal areas of Kenya, Tanzania, Madagascar and Mozambique, which together account for 5% of the world’s mangroves.
- The report finds the majority of WIO mangrove loss was driven by unsustainable wood extraction, land clearance for agriculture and the impacts of storms and flooding.
- Mangroves provide vital ecosystem services to coastal communities and habitats, and sequester large amounts of carbon.
Biomass cofiring loopholes put coal on open-ended life support in Asia
- Over the past 10 years, some of Asia’s coal-dependent, high-emitting nations have turned to biomass cofiring (burning coal and biomass together to make electricity) to reduce CO2 emissions on paper and reach energy targets. But biomass still generates high levels of CO2 at the smokestack and adds to dangerous global warming.
- In South Korea, renewable energy credits given for biomass cofiring flooded the market and made other renewables like wind and solar less profitable. Although subsides for imported biomass for cofiring have decreased in recent years, increased domestic biomass production is likely to continue fueling cofiring projects.
- In Japan, renewable energy subsidies initially prompted the construction of new cofired power plants. Currently, biomass cofiring is used to make coal plants seem less polluting in the near term as utilities prepare to cofire and eventually convert the nation’s coal fleet to ammonia, another “carbon-neutral” fuel.
- In Indonesia, the government and state utility, encouraged by Japanese industry actors, plan to implement cofiring at 52 coal plants across the country by 2025. The initiative will require “nothing less than the creation of a large-scale biomass [production] industry,” according to experts.
What’s the chance of meeting Paris climate goal? Just 0.1%, study says
- Under the 2015 Paris climate accord, nearly 200 countries committed to reducing the carbon emissions that fuel climate change and keeping global warming under 2˚C (3.6°F), or 1.5 ˚C (2.7°F) if possible.
- The 1.5°C goal requires global greenhouse emissions to be cut by 45% by 2030 and brought down to net zero by 2050, which is extremely unlikely to happen, a new analysis has found.
- Even if mean temperatures were held below 2°C, people living in the tropics, in particular in India and sub-Saharan Africa, will be exposed to extreme heat for most days of the year, researchers warned.
- In the mid-latitude zone, which includes the U.S. and most of the European Union and the U.K., deadly heat waves could strike every year by 2100.
Poverty-fueled deforestation threatens Kenya’s largest water catchment
- Mau Forest is East Africa’s largest native montane forest and Kenya’s largest water catchment.
- Olpusimoru Forest Reserve is one of Mau Forest’s protected areas, but its forest cover has been greatly reduced by logging, fuelwood collection and other poverty-driven human pressures.
- Beginning in 2018, thousands of families that had established themselves inside the forest reserve’s boundaries were evicted by the Ministry of Environment and Forestry, part of a wider push that saw more than 30,000 people evicted from the broader Mau Forest Complex.
- Despite government intervention and civil society initiatives to assuage poverty in the region, signs of fresh logging, charcoal burning and overgrazing are evident in Olpusimoru Forest Reserve.
Niger Delta mangroves in ‘grave danger’ from oil spills, poverty, invasive species
- Southern Nigeria’s vast Niger Delta boasts Africa’s most extensive mangrove forests — and some of the world’s largest fossil fuel reserves.
- Efforts to extract oil and gas have resulted in numerous oil spills, which have damaged the region’s biodiversity, as well as the livelihoods of coastal communities.
- Niger Delta mangroves are also affected by logging, farming and urban expansion, and are being replaced by invasive nipa palm.
- Research suggests Niger Delta’s mangroves could be gone within 50 years at the current rate of loss.
As stronger storms hit Bangladesh farmers, banks are climate collateral damage
- Farmers in coastal areas of Bangladesh are increasingly defaulting on their loans due to climate change-driven storms that are destroying the farms they put up as collateral.
- Agricultural loans for the year to May 2022 amounted to the equivalent of $3 billion, or a fifth of the value of all loans distributed in Bangladesh.
- Increasingly frequent and severe storms therefore pose as much of a threat to the country’s financial sector as to farming communities and the environment.
- The warming of the sea in the Bay of Bengal as a result of climate change is supercharging storms, giving them more energy, helping them to drive tidal surges farther inland and dump larger volumes of rain than before.
We’ve crossed the land use change planetary boundary, but solutions await
- According to experts, we have passed the planetary boundary for land systems change — the human-caused loss of forest — and risk destabilizing Earth’s operating systems.
- Scientists calculate we must retain 85% of tropical and boreal forests, and 50% of temperate forests, to stay within Earth’s “safe operating” bounds, but the number of trees worldwide has fallen by nearly 50% since the dawn of agriculture.
- From 2001 to 2021, forest area roughly half the size of China was lost or destroyed across the planet; in 2021, tropical forests disappeared at a rate of about 10 football fields per minute.
- Despite these losses, solutions abound: Some of the actions that could bring us back into the safe operating space are securing Indigenous land rights, reforestation and landscape restoration, establishing new protected areas, redesigning food systems, and using finance as a tool
Sea life may downsize with ocean warming — bringing challenging impacts
- A new model predicts that marine microbes could shrink by up to 30% in the future due to climate change, impacting bigger organisms that eat them including fish, potentially disrupting the food chain from the bottom up. Smaller fish would mean impacted fisheries. Smaller microbes could mean less carbon sequestration.
- Warmer oceans hold less oxygen, and the model predicts that sea life will get smaller in response to more limited oxygen. But scientists have long debated why this downsizing occurs, and some say that other factors not considered in the model could impact oceanic microbes in unexpected ways.
- Accurately predicting warming impacts on marine life could improve ocean resource management.
Deforestation intensifies in northern Malaysia’s most important water catchment
- The Ulu Muda rainforest is one of the last large, continuous tracts of forest in the Malay Peninsula, providing vital habitat for countless species as well as water for millions of people in northern Malaysia.
- Satellite data indicate deforestation activities are intensifying in the greater Ulu Muda landscape, including in protected areas such as Ulu Muda Forest Reserve.
- Sources say the forest loss is likely due to legal logging.
- Conservationists worry that the loss of Ulu Muda rainforest will have detrimental impacts on the region’s biodiversity and water security, as well as contribute to global climate change.
In Congo, a carbon sink like no other risks being carved up for oil
- New research has revealed that the peatlands of the Congo Basin are 15% larger than originally thought.
- This area of swampy forest holds an estimated 29 billion metric tons of carbon, which is the amount emitted globally through the burning of fossil fuels in three years.
- Beginning July 28, the government of the Democratic Republic of Congo, where two-thirds of these peatlands lie, will auction off the rights to explore for oil in 27 blocks across the country.
- Scientists and conservationists have criticized the move, which the government says is necessary to fund its operations. Opponents say the blocks overlap with parts of the peatlands, mature rainforest, protected areas, and a UNESCO World Heritage site.
Rains quell fire risk around Cambodia’s Tonle Sap, but the future looks fiery
- Cambodia has received an unusually high volume of rain since December, generally the start of the dry season, which has led to a relative lull in fire activity.
- According to NASA satellite data, there were only two high-confidence fire alerts reported in the forested area around Tonle Sap, Cambodia’s largest lake, between April 1 and July 1 this year, compared to 45 such alerts recorded during the same period in 2021.
- This year’s heavy rain, while a welcome respite, isn’t expected to last as temperatures rise and droughts increase in frequency due to climate change.
- Tonle Sap’s water levels have already been dropping for years, according to authorities; to mitigate future threats, the Department of Fisheries Conservation is rolling out provincial-level plans to respond to forest fires in the lake’s drying floodplain.
As biomass burning surges in Japan and South Korea, where will Asia get its wood?
- In 2021, Japan and South Korea imported a combined 6 million metric tons of wood pellets for what proponents claim is carbon-neutral energy.
- Large subsidies for biomass have led Japan to import massive amounts of wood pellets from Vietnam and Canada; two pellet giants, Drax and Enviva, are now eyeing Japan for growth, even as the country may be cooling to the industry.
- South Korea imports most of its pellets from Vietnamese acacia plantations, which environmentalists fear may eventually pressure natural forests; South Korea wants to grow its native production sixfold, including logging areas with high conservation value.
- Vietnam may soon follow Japan and South Korea’s path as it phases out coal, and experts fear all this could add massive pressure on Southeast Asian forests, which are already among the most endangered in the world.
Vandana Shiva on the agroecology solution for the climate, biodiversity crisis and hunger
- On this episode we talk about agroecology, which applies ecological principles to agricultural systems and is considered an important strategy for both mitigating and adapting to global climate change as well as a solution to a number of the other ecological crises we're facing.
- Dr. Maywa Montenegro, an assistant professor in the department of environmental studies at the University of California, Santa Cruz, joins us to discuss agroecology as a science, a practice, and a movement.
- We also speak with Dr. Vandana Shiva, whose brand new book synthesizes decades of agroecology research and implementation.
- Dr. Shiva shares how agroecology is an effective solution not just to climate change but also to a host of other ecological crises humanity faces, such as water scarcity, land degradation, and biodiversity loss.
EU Parliament’s Environment Committee urges scale back of biomass burning
- The European Parliament’s Environment Committee this week made strong, but nonbinding, recommendations to put a brake on the EU’s total commitment to burning forest biomass to produce energy. While environmentalists cautiously hailed the decision, the forestry industry condemned it.
- A key recommendation urges that primary woody biomass (that made from whole trees) to produce energy and heat no longer receive government subsidies under the EU’s revised Renewable Energy Directive (RED).
- Another recommendation called for primary woody biomass to no longer be counted toward EU member states’ renewable energy targets. Currently, biomass accounts for 60% of the EU’s renewable energy portfolio, far more than zero-carbon wind and solar.
- The Environment Committee recommendations mark the first time any part of the EU government has questioned the aggressive use of biomass by the EU to meet its Paris Agreement goals. A final decision by the EU on its biomass burning policies is expected in September as part of its revised Renewable Energy Directive.
Oil exploration in DR Congo peatland risks forests, climate and local communities
- The Democratic Republic of Congo is putting 16 oil exploration blocks up for auction, including nine in the peatlands of the Cuvette Centrale.
- Environmentalists warn that oil exploration and infrastructure for production could release huge amounts of carbon stored in the peatland and threaten the rights of local communities.
- The Congolese government says it needs to exploit its natural resources in order to generate income to develop the country, much as countries in other parts of the world have done before it.
Missing the emissions for the trees: Biomass burning booms in East Asia
- Over the past decade, Japan and South Korea have increasingly turned to burning wood pellets for energy, leaning on a U.N. loophole that dubs biomass burning as carbon neutral.
- While Japan recently instituted a new rule requiring life cycle greenhouse gas emissions accounting, this doesn’t apply to its existing 34 biomass energy plants; Japanese officials say biomass will play an expanding role in achieving Japan’s goal of reducing greenhouse gas emissions by 46% by 2030.
- South Korea included biomass burning in its renewable energy portfolio standard, leading to 17 biomass energy plants currently operating, and at least four more on the way.
- Experts say these booms in Asia — the first major expansion of biomass burning outside Europe — could lead to a large undercounting of actual carbon emissions and worsening climate change, while putting pressure on already-beleaguered forests.
Cradle of transformation: The Mediterranean and climate change
- The Mediterranean region is warming 20% faster than the world as a whole, raising concerns about the impacts that climate change and other environmental upheaval will have on ecosystems, agriculture and the region’s 542 million people.
- Heat waves, drought, extreme weather and sea-level rise are among the impacts that the region can expect to see continue through the end of the century, and failing to stop emissions of carbon dioxide and other greenhouse gases could make these issues worse.
- Charting a course that both mitigates climate change and bolsters adaption to its effects is further complicated by the Mediterranean’s mix of countries, cultures and socioeconomics, leading to wide gaps in vulnerability in the region.
Tropical trees’ growth and CO2 intake hit by more extreme dry seasons
- A new study has found that dry seasons that are warmer and drier than usual can stunt the growth of tropical trees, causing them to take in less carbon dioxide.
- While trees tend to grow more during the wet season, the researchers found that the dry season actually had a stronger impact on tree growth than the wet season.
- As climate change continues to raise temperatures, tropical trees could face increased risk of mortality and the possibility of becoming a net source of carbon, rather than a carbon sink.
Robot revolution: A new real-time accounting system for ocean carbon
- Oceans are key to understanding climate change, seeing as they take up and store 25% of the carbon that human activities add to Earth’s atmosphere. But there are big gaps in our knowledge regarding ocean carbon storage and release, and how it is evolving as climate change unfolds, a problem scientists are now addressing.
- An international deployment of thousands of robotic floats, fitted with sophisticated biogeochemical sensors, is underway and already providing real-time data that scientists can integrate into ocean carbon budgets and climate models. Many more floats are coming, with the capacity to operate in remote regions.
- One such place is the Southern Ocean around Antarctica, which accounts for almost half of the worldwide oceanic carbon sink. Windier conditions there, caused by climate change, are churning up more carbon-rich waters from the depths, releasing stored carbon and introducing unforeseen variability into ocean carbon emission estimates.
- Robots are starting to monitor these emissions in real time. More accurate ocean carbon budgets will improve accounting of land-based carbon dioxide emissions, help create more accurate assessments of how well global carbon agreements such as the Paris Agreement are meeting goals, and will help assess ocean carbon dioxide removal plans.
Climate pledges could limit warming to 2C. What’s needed is action, study says
- A new study has suggested that global temperatures can be limited to 2°C (3.6°F) above pre-industrial levels if countries fully meet all of their climate pledges on time.
- However, the researchers say that rapid action is needed within the decade to meet the targets necessary to fulfill this goal.
- This analysis comes shortly after the publication of the United Nations’ Intergovernmental Panel on Climate Change’s (IPCC) latest report, which says that greenhouse gas emissions must peak by 2025 and nations need to reach net-zero emissions by the 2050s.
IPCC report calls for ‘immediate and deep’ carbon cuts to slow climate change
- A new report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) finds that the world could face a more than 3° Celsius (5.4° Fahrenheit) increase in the global average temperature over pre-industrial levels based on current carbon emissions.
- However, the authors of the report say investment in renewable energy, green building and responsible land use could lower emissions enough to stay below an increase of 1.5°C (2.7°F), a target identified at the 2015 U.N. climate conference that scientists predict would avoid the worst impacts of global warming.
- Addressing continued global carbon emissions will require trillions, not billions, of dollars in financing from public and private sources to cut emissions, the report finds.
- Its authors also say that including Indigenous and local communities from the beginning in land-use decisions aimed at climate change mitigation is critical.
The Great Barrier Reef is bleaching — once again — and over a larger area
- The Great Barrier Reef is currently experiencing its sixth mass bleaching event, and the fourth event of this kind to happen in the past six years.
- Based on aerial surveys that were concluded this week, bleaching has affected all parts of the Great Barrier Reef, with the most severe bleaching occurring between Cooktown, Queensland, and the Whitsunday Islands.
- Sea surface temperatures around the Great Barrier Reef have been higher than normal, despite the region going through a La Niña climate pattern, which usually brings cooler, stormier weather.
- Climate change remains the biggest threat to the Great Barrier Reef and other reefs around the world, experts say.
Multiyear ice thinner than thought as Arctic sea ice reaches winter max: Studies
- Arctic sea ice has reached its yearly maximum extent at 14.88 million sq. km., the 10th lowest on record. The up-and-down story of sea ice extent in the past year highlights how unpredictable it can be from season to season, even as the overall decline continues.
- A study employing new satellite data found that Arctic multiyear sea ice — ice that survives the summer melt — is thinning even faster than previously thought and has lost a third of its volume in just two decades.
- This comes as Antarctic sea ice extent hit a record summer low, raising questions whether it is beginning a long-term decline, although experts are wary of drawing conclusions yet.
- While summer Arctic sea ice is predicted to mostly disappear by 2050, a new study suggests we could likely preserve it through 2100 by aggressively cutting methane emissions by 2030, along with reaching net-zero CO2 emissions by 2050.
Tropical deforestation emitting far more carbon than previously thought: Study
- Carbon emissions due to tropical deforestation are accelerating, a new study has found.
- Using detailed maps of forest change as well as aboveground and soil carbon deposits, the researchers demonstrate that annual emission more than doubled between 2015-2019, compared with 2001-2005.
- Though the study reveals that the world has not met its commitments to stem deforestation, the authors say it also reveals that investments in forest protection and restoration are critical to addressing climate change.
Activists vow to take EU to court to fight its forest biomass policies
- The European Union continues burning forest biomass to produce energy, a policy science has shown to be climate destabilizing, destructive to forests and biodiversity. International NGOs and their lawyers — to stop the EU going further down what they see as a path of planetary endangerment — is ready to take the EU to court.
- The plaintiffs contend that the European Union is violating its own rules dictating that European Commission policies be based in “environmentally sustainable economic practices” for companies, investors and policymakers.
- Activists argue that the EU, in creating its current bioenergy and forestry policies, has disregarded numerous scientific studies demonstrating the environmental harm done by forest biomass — the harvesting and burning of wood pellets to make electricity. Some legal experts say the activists’ bid to be heard in court is a long shot.
- A November study adds data and urgency to the ongoing battle. Researchers found that unless current policies change, global demand for biomass-for-energy will triple by 2050, further impacting intact forests ability to act as carbon sinks and undermining emissions-reduction requirements under the Paris Agreement.
Are ‘nature based solutions’ the best fix for climate change?
- On today's episode of the Mongabay Newscast, we discuss mangrove restoration and other nature based solutions to climate change.
- We speak with Alfredo Quarto, co-founder and program and policy director of the Mangrove Action Project, who tells us about the ongoing destruction of mangrove forests around the world, why it’s so important to restore these coastal ecosystems, and what makes for successful mangrove restoration projects.
- We also speak with Norah Berk, a policy advisor on climate change and forests at the Rainforest Foundation UK, who tells us that nature based solutions have, in many cases, been co-opted by corporations that are using them as part of carbon offset schemes, and discusses why she thinks land titling for Indigenous and local communities is the solution to climate change that we should be focusing on.
Climate change set to upend global fishery agreements, study warns
- The warming of the world’s oceans by climate change is pushing fish away from their current habitats and toward Earth’s poles.
- By 2030, scientists predict a quarter of the global shared fish stocks could move, a new study says, with about three-quarters of countries seeing at least one fish species move out of their exclusive economic zone.
- Countries in the tropics, especially those in the Caribbean, Latin America, Oceania and South Asia, could experience the shifts earlier; and while some countries stand to benefit at the expense of others, these shared fish stock movements could upend current fisheries agreements, leading to disputes.
- To avert disputes, countries could renegotiate current catch quotas to factor in the effects of climate change-driven fish movements, the study authors say.
As rising seas destroy Ghana’s coastal communities, researchers warn against a seawall-only solution
- Some 37% of Ghana’s coastal land was lost to erosion and flooding between 2005 and 2017.
- Severe storm surges flooded several communities in 2021, prompting the evacuation of thousands of people.
- Research indicates around 340 million people worldwide will be affected by global warming-fueled sea level rise by the middle of the century. Ghana’s government is responding to the growing crisis by fortifying some coastal areas with seawalls, but researchers say relying on seawalls alone may do more harm than good.
- This story was produced with support from the Pulitzer Center.
Aerosol pollution: Destabilizing Earth’s climate and a threat to health
- Aerosols are fine particulates that float in the atmosphere. Many are natural, but those haven’t increased or decreased much over the centuries. But human-caused aerosols — emitted from smokestacks, car exhausts, wildfires, and even clothes dryers — have increased rapidly, largely in step with greenhouse gases responsible for climate change.
- Aerosol pollution kills 4.2 million people annually, 200,000 in the U.S. alone. So curbing them rapidly makes sense. However, there’s a problem with that: The aerosols humanity sends into the atmosphere presently help cool the climate. So they protect us from some of the warming that is being produced by continually emitted greenhouse gases.
- But scientists still don’t know how big this cooling effect is, or whether rapidly reducing aerosols would lead to a disastrous increase in warming. That uncertainty is caused by aerosol complexity. Atmospheric particulates vary in size, shape and color, in their interactions with other particles, and most importantly, in their impacts.
- Scientists say that accurately modeling the intensity of aerosol effects on climate change is vital to humanity’s future. But aerosols are very difficult to model, and so are likely the least understood of the nine planetary boundaries whose destabilization could threaten Earth’s operating systems.
Climate change a threat to human well-being and health of the planet: New IPCC report
- The United Nations’ Intergovernmental Panel on Climate Change (IPCC) released a report on the impacts of climate change on people, detailing areas of vulnerability and steps for adaptation to the changes brought about by Earth’s warming temperatures.
- The report, the second of three that will be part of the IPCC’s sixth assessment, highlights the importance of Indigenous and local knowledge in grappling with climate change and its effects on weather, water availability and food sources.
- It also notes that some segments of society, especially the most vulnerable, will bear a disproportionate burden as a result of climate change.
- The authors of the report and other climate researchers emphasize that urgent action is needed, both to address the causes of climate change and improve the capability of people to adapt to it.
‘They’re going to get worse and worse’: Marine heat wave persists off Sydney
- In November 2021, an unusual marine heat wave materialized off the coast of Sydney; sea surface temperatures in the area have yet to go down.
- This marine heat wave is just one of numerous events occurring across the global oceans as human-induced climate change heats up the oceans.
- While marine heat waves can be triggered by a range of atmospheric, oceanic and climatic drivers, climate change plays a key role in driving these events.
Malaysian officials dampen prospects for giant, secret carbon deal in Sabah
- The attorney general of the Malaysian state of Sabah has said that a contentious deal for the right to sell credits for carbon and other natural capital will not come into force unless certain provisions are met.
- Mongabay first reported that the 100-year agreement, which involves the protection of some 2 million hectares (4.9 million acres) from activities such as logging, was signed in October 2021 between the state and a Singapore-based firm called Hoch Standard.
- Several leaders in the state, including the attorney general, have called for more due diligence on the companies involved in the transaction.
- Civil society representatives say that a technical review of the agreement is necessary to vet claims about its financial value to the state and its feasibility.
Efforts to dim Sun and cool Earth must be blocked, say scientists
- Scientists are calling on political institutions to place limits on solar geoengineering research so that it cannot be deployed unilaterally by countries, companies or individuals.
- Long-term planetary-level geoengineering interventions of this kind are unprecedented and extremely dangerous, say the academics behind the letter, and should not therefore be experimented with outdoors, receive patents, public funds or international support.
- Solar geoengineering’s leading proposal — injecting billions of aerosol particles into the Earth’s stratosphere — could have severe, unintended and unforeseen consequences. Modelling suggests that it may cause drying in the Amazon rainforest
- In addition, if solar geoengineering were deployed, it would need to be maintained for decades. Sudden discontinuance would result in Earth facing what scientists call termination shock, with a sudden temperature rise due to existing atmospheric carbon emissions which would have been masked by cooling stratospheric aerosols.
In Africa, temperatures rise, but adaptation lags on West’s funding failure
- Last year was the third-warmest year for the continent, tied with 2019, with warming more pronounced here than the global average.
- The annual temperature in 2021 was 1.33°C (2.39°F) above average for the continent, with West and North Africa seeing an unusually warm year.
- Extreme events and long-drawn catastrophes are taking a toll and sapping resilience, while adaptation efforts are failing due to planning gaps and financing woes.
- Committed finance for adaptation is pegged at $2.7 billion to $5.3 billion annually, but the estimated cost of coping with climate impacts is almost double that.
Small coffee farmers lay their chips on smart agriculture to overcome climate crisis in the Cerrado biome
- A long drought followed by a strong freeze in 2020 damaged the coffee harvest in Brazil, the world’s biggest producer and exporter of the crop.
- Small farmers in the Cerrado region who generally don’t use irrigation because of the area’s historically abundant rainfall were hit the hardest.
- To take on the challenges brought on by the changing climate, coffee farmers in the Cerrado have joined a climate-smart agriculture program.
- The strategies adopted for more resilient crops include agroforestry, connected landscapes, and water resource management.
Global ecosystem restoration progress: How and who’s tracking it?
- Nature-based climate solutions currently being widely touted include the restoration of the world’s degraded forests and other ecosystems in order to store more carbon. But while many restoration pledges have been made by many nations via many initiatives, the monitoring and tracking of their success remains murky.
- That’s because, while deforestation can easily be seen from satellites, effective and accurate ecosystem restoration tracking requires systems for long-term ground-truthing, for measuring carbon storage over decades, and for improvements in biodiversity and the boosting of local economies.
- Among the many ecosystem restoration initiatives now underway are the 2021 Glasgow Forest Declaration and the Bonn Challenge, along with the restoration commitments made as part of national emissions reductions plans under the Paris Climate Agreement (nationally determined contributions or NDCs).
- Strides toward better restoration tracking are being made by initiatives like the Bonn Challenge’s Restoration Barometer and the Brazilian Restoration and Reforestation Observatory — though more work is needed to secure globally accurate tracking.
Congo Peatlands
In 2017 a team of Congolese and British scientists discover that a sprawling wetland known as the Cuvette Centrale spanning the border between the Republic of Congo and the Democratic Republic of Congo (DRC) actually contains a massive amount of peat. Their research revealed that these peatlands are the largest and most intact across the world’s […]
As climate-driven drought slams farms in U.S. West, water solutions loom
- Drought in the U.S. West has been deepening for two decades, with no end in sight. Unfortunately for farmers, water use policies established in the early 20th century (a time of more plentiful rainfall), have left regulators struggling with their hands tied as they confront climate change challenges — especially intensifying drought.
- However, there is hope, as officials, communities and farmers strive to find innovative ways to save and more fairly share water. In Kansas and California, for example, new legislation has been passed to stave off dangerous groundwater declines threatening these states’ vital agricultural economies.
- Experts say that while an overhaul of the water allocation system in the West is needed, along with a coherent national water policy, extreme measures could be disruptive. But there are opportunities to realize incremental solutions now. Key among them is bridging a gap between federal water programs and farmers.
- A major concern is the trend toward single crop industrial agribusiness in semi-arid regions and the growing of water-intensive crops for export, such as corn and rice, which severely depletes groundwater. Ultimately, 20th century U.S. farm policies will need to yield to flexible 21st century policies that deal with unfolding climate change.
Indigenous leader sues over Borneo natural capital deal
- An Indigenous leader in Sabah is suing the Malaysian state on the island of Borneo over an agreement signing away the rights to monetize the natural capital coming from the state’s forests to a foreign company.
- Civil society and Indigenous organizations say local communities were not consulted or asked to provide input prior to the agreement’s signing on Oct. 28.
- Further questions have arisen about whether the company, Hoch Standard, that secured the rights under the agreement has the required experience or expertise necessary to implement the terms of the agreement.
The past, present and future of the Congo peatlands: 10 takeaways from our series
This is the wrap-up article for our four-part series “The Congo Basin peatlands.” Read Part One, Part Two, Part Three and Part Four. In the first half of December, Mongabay published a four-part series on the peatlands of the Congo Basin. Only in 2017 did a team of Congolese and British scientists discover that a […]
Carbon and communities: The future of the Congo Basin peatlands
- Scientific mapping in 2017 revealed that the peatlands of the Cuvette Centrale in the Congo Basin are the largest and most intact in the world’s tropics.
- That initial work, first published in the journal Nature, was just the first step, scientists say, as work continues to understand how the peatlands formed, what threats they face from the climate and industrial uses like agriculture and logging, and how the communities of the region appear to be coexisting sustainably.
- Researchers say investing in studying and protecting the peatlands will benefit the global community as well as people living in the region because the Cuvette Centrale holds a vast repository of carbon.
- Congolese researchers and leaders say they are eager to safeguard the peatlands for the benefit of everyone, but they also say they need support from abroad to do so.
‘Cooling the climate for 10,000 years’: How saving wetlands can help save the world
- From the vast frozen mires of the arctic to the peat swamps of Asia: “all wetlands are under threat,” said Jane Madgwick, CEO of Wetlands International. “We’re losing them three times as fast as forests.”
- Peat swamps, or peatlands, are particularly effective at storing carbon, which has accumulated over centuries and even millennia as dead plant matter became trapped in waterlogged soil.
- But if drained or otherwise damaged, peat quickly turns from carbon sink to carbon source.
- As nations race to protect and replant forests in an effort to curtail global warming, wetlands experts such as Madgwick are urging leaders to place similar importance on wetland conservation and restoration.
Climate change agricultural impacts to heighten inequality: Study
- Major changes in crop productivity will be felt globally in the next 10 years according to new computer simulations. Climate impacts on crops could emerge a decade sooner than previously expected in major breadbasket regions in North America, Europe and Asia according to the new forecasts.
- Researchers combined five new climate models with 12 crop models, creating the largest, most accurate set of yield simulations to date. Corn could see yield declines of up to 24% by 2100, while wheat may see a boost to productivity. In some sub-tropical regions, climate impacts on crops are already being felt.
- High- and low-emissions scenarios project similar trends for the next 10 years, suggesting these agricultural impacts are locked-in. But actions taken now to mitigate climate change and alter the long-term climate trajectory could limit corn yield losses to just 6% by 2100.
- Climate adaptation measures such as sowing crops earlier or switching to heat- tolerant cultivars are relatively cheap and simple to implement, while other actions, such as installing new irrigation systems, require financial investment, planning, and time.
Holding agriculture and logging at bay in the Congo peatlands
- The peatlands of the Congo Basin are perhaps the most intact in the tropics, but threats from logging, agriculture and extractive industries could cause their rapid degradation, scientists say.
- In 2021, the government of the Democratic Republic of Congo (DRC) announced that it was planning to end a moratorium on the issuance of logging concessions that had been in place for nearly two decades.
- The move raised concerns among conservation groups, who say the moratorium should remain in place to protect the DRC’s portion of the world’s second-largest rainforest.
- Today, timber concession boundaries overlap with the peatlands, and though some companies say they won’t cut trees growing on peat, environmental advocates say that any further issuance of logging concessions in the DRC would be irresponsible.
Layers of carbon: The Congo Basin peatlands and oil
- The peatlands of the Congo Basin may be sitting on top of a pool of oil, though exploration has yet to confirm just how big it may be.
- Conservationists and scientists argue that the carbon contained in this England-size area of peat, the largest in the tropics, makes keeping them intact more valuable, not to mention the habitat and resources they provide for the region’s wildlife and people.
- Researchers calculate that the peatlands contain 30 billion metric tons of carbon, or about the amount humans produce in three years.
- As the governments of the Republic of Congo and the Democratic Republic of Congo work to develop their economies, they, along with many policymakers worldwide, argue that the global community has a responsibility to help fund the protection of the peatlands to keep that climate-warming carbon locked away.
The ‘idea’: Uncovering the peatlands of the Congo Basin
- In 2017, a team of scientists from the U.K. and the Republic of Congo announced the discovery of a massive peatland the size of England in the Congo Basin.
- Sometimes called the Cuvette Centrale, this peatland covers 145,529 square kilometers (56,189 square miles) in the northern Republic of Congo and the Democratic Republic of Congo, and holds about 20 times as much carbon as the U.S. releases from burning fossil fuels in a year.
- Today, the Congo Basin peatlands are relatively intact while supporting nearby human communities and a variety of wildlife species, but threats in the form of agriculture, oil and gas exploration and logging loom on the horizon.
- That has led scientists, conservationists and governments to look for ways to protect and better understand the peatlands for the benefit of the people and animals they support and the future of the global climate.
Is colonial history repeating itself with Sabah forest carbon deal? (commentary)
- To the surprise of Indigenous and local communities, a huge forest carbon conservation agreement was recently signed in the Malaysian state of Sabah on the island of Borneo.
- Granting rights to foreign entities on more than two million hectares of the state’s tropical forests for the next 100-200 years, civil society groups have called for more transparency.
- “Is history repeating itself? Are we not yet free or healed from our colonial and wartime histories?” wonders a Sabahan civil society leader who authored this opinion piece calling for more information, more time, and a say.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
In a warming world, deforestation turns the heat deadly, Borneo study finds
- New research identifies how rising localized temperatures driven by deforestation and global warming are increasing heat-related deaths and creating unsafe working conditions in Indonesia.
- In the Bornean district of Berau, 4,375 square kilometers (1,689 square miles) of forest were cleared between 2002 and 2018, contributing to a 0.95°C (1.71°F) increase in mean daily temperature across the district, according to the study.
- It concluded climate change temperature increases in the region caused an 8% rise in mortality rates in 2018, or more than 100 deaths annually, and an additional almost 20 minutes per day of unsafe work time.
- Based on the 2018 data, a projected 2°C (3.6°F) global temperature increase in deforested areas could result in a 20%increase in all-cause mortality — an additional 236-282 deaths per year — and almost five unsafe work hours per day.
Fighting climate change is a dirty job, but soils can do it | Problem Solved
- The Earth’s soil stores nearly three times as much carbon as all plants, animals and the atmosphere combined, researchers say.
- However, unchecked deforestation, modern industrialized agriculture, the failure to recognize Indigenous land rights, and the continued extraction and burning of fossil fuels are all putting our crucial carbon sinks in the tropics and subarctic permafrost at risk of releasing much of that carbon.
- Experts agree that protecting soil is key to mitigating climate change, and to avoid breaching delicate planetary boundaries that are necessary to sustain human life on the planet.
- Doing so means fundamental shifts in how we grow our food, conserve and restore forests, and swiftly reduce our use of fossil fuels.
Details emerge around closed-door carbon deal in Malaysian Borneo
- Leaders in Sabah have begun to reveal information about a nature conservation agreement signed in the Malaysian state of Sabah on the island of Borneo for the rights to carbon and other natural capital.
- The deal allegedly covers rights to more than 2 million hectares (4.9 million acres) of the state’s tropical forests for the next 100-200 years.
- Indigenous and civil society groups have called for more transparency.
- In response to the public reaction to news of the agreement, its primary proponent, Deputy Chief Minister Jeffrey Kitingan, held a public meeting but has declined to make the agreement public yet.
Hope old and new: COP26 focused on two largely unsung climate solutions
- COP26 ended with wide disagreement as to its degree of success. But two major climate solution discussions that happened at COP could yield important results if nations and the international community commit to them.
- A great deal of attention at COP26 focused on the key role Indigenous communities living in tropical nations could play in protecting and sustaining carbon-sequestering forests on their ancestral lands. But Indigenous peoples can only play that role if fully supported by tropical countries and the international community.
- A new study found that Indigenous Peoples and Local Communities (IPLCs) now hold and use tropical lands nearly equivalent in size to the continental U.S., but have legally recognized rights to less than half that area. To curb climate change, these ancestral lands need to be fully restored to the IPLCs, with land rights vigorously protected by governments.
- Another potential solution, atmospheric methane removal, was well discussed at COP26 and has resulted in plans for upcoming meetings between scientists and U.S. and Canadian policymakers. Methane removal is still in the experimental stage, and needs significant government funding to take it to the next level: field testing.
‘Standing with your feet in the water’: COP26 struggles to succeed
- As at every COP before it, negotiators at COP26 are struggling against time to reach an accord, with negotiators at Glasgow clashing over seemingly irreconcilable differences. With the science of climate change now dire, vulnerable nations are demanding strong specific language, while other nations seek to water it down.
- The group of nations dubbed the “Carbon Club” as long ago as the Kyoto Agreement negotiations in the 1990s, continues to offer the primary stumbling block. Those oil and/or coal producing nations include Russia, Saudi Arabia, China, Australia, Norway, the U.K. and often the U.S.
- The United States, while it has made a major sea change since the denialism of the Trump administration, continues to be cautious about any language that would threaten oil, gas and coal industry subsidies, or antagonize Republican members of Congress or coal company baron and West Virginia Dem. Sen. Joe Manchin.
- As the clock ticks, and the last hours of COP26 slip away, with street protestors increasingly frustrated at the lack of significant movement by the negotiators, the scene remains tense in Glasgow. With the summit now gone into overtime, the outcome of COP26 remains in the balance.
COP26: Are climate declarations and emission reduction pledges legally binding?
- The 2015 Paris Agreement is not a treaty between nations, but rather a voluntary accord between 194 nations signed by their legal representatives. As such, it is not deemed legally binding — preventing nations and corporations from being sued to force them to take legal responsibility for harmful carbon emissions and policies.
- Or at least, that was the accepted legal precedent regarding the Paris accord, as well as declarations and agreements made since 2015 at annual COP summits. This includes this year’s Glasgow U.K. climate conference where major declarations to end global deforestation and sharply curb methane emissions were made.
- However, some 1,800 lawsuits seeking to hold nations and corporations responsible for their climate change pledges and emissions are moving through the worlds’ legal systems. At least one major case has borne fruit: In May 2021, a court in The Netherlands ordered Royal Dutch Shell to slash carbon emissions far faster than pledged.
- It wasn’t international law that decided the case, but basic tort law: a legal obligation to not knowingly injure others. “Rights-based climate litigation is not some kind of scholarly fantasy; rather, it is turning out to be one of the most important tools civil society has to force governments to move more quickly,” says one legal expert.
COP26: E.U. is committed to forest biomass burning to cut fossil fuel use
- At COP26, Frans Timmermans, the European Commission’s executive vice president, made clear that the E.U. is committed to ending its addiction to oil, gas and coal, but only if it can use the bridge of burning forest biomass to get to an eventual goal of fully utilizing truly renewable energy sources, like wind and solar.
- Timmermans maintains that the E.U. is committed to only burning “the right kind of biomass: You can collect dead wood, you can collect those elements of the forests that are no longer alive, fallen down, etc. That constitutes a serious amount of biomass.… As long as your definition is sustainable… we can work with biomass.”
- A forestry industry representative agrees: “The biomass we are currently using in Europe is about 95% based on local resources — that is residues from forestry and wood processing originating from Europe… We are currently harvesting significantly less than is regrowing annually in Europe.”
- But critics say whole trees are being burned to make wood pellets and ask how the E.U. can commit to both biomass burning and protecting carbon-storing forests. “No amount of allegedly nicer forest management can overcome the basic problem of large, immediate emissions from burning tons of biomass daily,” said one activist.
COP26: Surging wood pellet industry threatens climate, say experts
- With the U.N. climate summit (COP26) in its second week, Earth is on track to warm by 2.7° Celsius (4.86° Fahrenheit) by 2100, a catastrophic forecast based on projected carbon emissions. However, analysts say that those projections exclude major emissions currently escaping from biomass-burning power plants.
- A carbon accounting loophole in global climate change policy classifies burning woody biomass for energy as “carbon neutral,” and is accepted by the U.N. and many of the world’s nations. But scientists have proven otherwise, even as the forestry industry gets massive subsidies to produce millions of tons of wood pellets annually.
- Those subsidies are fueling rapid growth of the biomass industry, as forests are cut in the U.S., Canada, Eastern Europe, Russia, Vietnam, and Malaysia. The E.U. and U.K. are the largest biomass energy market, but with rapid expansion now occurring in Japan and South Korea, the biomass boom is just beginning.
- Scientists and activists say that to avoid disastrous global warming impacts, forest large biomass subsidies must end, which will make the industry unprofitable and free up funding for real climate solutions. But the topic is not even on the COP26 agenda, and action on the biomass burning issue anytime soon seems unlikely.
New restoration “Playbook” calls for political, economic, and social change
- Leading forest and climate experts have come up with a “playbook” for ecosystem restoration that accounts for climate change and forest loss as not just biophysical and environmental problems, but also deeply political, economic and social issues.
- It defines 10 principles for effective, equitable, and transformative landscapes that its authors say could be game-changing if followed.
- The playbook discusses the importance of ending fossil fuel subsidies and shifting those resources toward ecosystem restoration, renewable energy, and supporting the land rights of local and Indigenous communities that are protecting forests.
- The authors invite IUCN members and leaders at COP26 in Glasgow to consider adopting the Playbook to guide biodiversity conservation, and climate change mitigation in forests and, more broadly, call for structural changes from local to international scale.
COP26: As carbon emissions rise unabated, scientists eye a methane removal fix
- The COP26 climate summit has moved into its second week, with no major climate change breakthroughs in sight. Just as alarming is a new investigation released today by The Washington Post showing that the world’s nations are hugely underreporting carbon emissions, making the race to truly curb carbon emissions even more urgent.
- As a result, COP26 negotiators and scientists are shifting their immediate attention from not only cutting CO2 emissions, but also slashing methane (CH4) emissions from fossil fuel, agricultural, and landfill sources. A hundred nations last week pledged to reduce methane emissions by 30% by 2030.
- Some scientists think they know the answer, suggesting a variety of engineering solutions to achieve rapid methane removal from the atmosphere — solutions which have been successful in the lab but remain untested in nature. COP26 attendees are said to be showing significant interest in this potential technology fix.
- However, there are numerous concerns, including the possible unforeseen public health and environmental impacts of methane removal technology, the challenge of upscaling and implementing the various proposed methods, and finding funding for the work. Perhaps the biggest hurdle is time, as climate change escalates apace.
Scientists urge Biden to remove logging, fossil fuels, biomass from budget bills
- More than 100 scientists have issued an open letter urging U.S. President Joe Biden and members of Congress to remove provisions promoting logging, forest biomass and fossil fuels from the multitrillion-dollar infrastructure and reconciliation (Build Back Better) bills.
- Both bills contain provisions for logging for lumber and for forest biomass energy, with the $1.2 trillion infrastructure bill passed by the U.S. House of Representatives on Nov. 5.
- Although the infrastructure bill promises $570 billion in tax credits and investments to combat climate change, it also includes a mandate for 12 million hectares (30 million acres) of “additional logging on federal public lands over the next 15 years.”
- “The logging and fossil fuel subsidies and policies in the Reconciliation and Infrastructure Bills will only intensify the rate and intensity of our changing climate,” the letter states.
COP26 deforestation-ending commitment must hold leaders accountable (commentary)
- Yesterday at COP26 world leaders announced an agreement to reverse and end deforestation within a decade.
- But lacking language on transparency, regular milestones, a binding legal framework, and a focus on human rights, this commitment may fail as others have before it.
- The New York Declaration on Forests of 2014 pledged to halve deforestation by 2020 and end it by 2030, yet rates of forest loss have been 41% higher in the years since. If world leaders are sincere about ending deforestation this time, there is one simple message: prove it.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
COP26 Glasgow Declaration: Salvation or threat to Earth’s forests?
- The U.N. climate summit underway in Glasgow, Scotland, served as a venue this week to announce the Glasgow Declaration on Forests and Land Use to the world. Signed by 100 countries representing 85% of the globe’s forested land, it pledges to end or reduce deforestation by 2030.
- The declaration comes on the heels of the failed 2014 New York Declaration for Forests–which had more than 200 national, private and civil service supporters–that promised to cut deforestation by 50% by 2020 and end it by 2030. Since then, deforestation has risen, contributing an estimated 23% of total carbon emissions.
- While some hailed this week’s Declaration, others warned that it’s $19.2 billion could be used to convert natural forests to plantations, which under current U.N. rules are counted as “forests.” Plantations to produce palm oil, paper or wood pellets (burnt to make energy), lack biodiversity and are less efficient at storing carbon.
- Said one NGO critical of the Glasgow Declaration: “Just as we must wind down use of fossil fuels, it’s also time for the industrial logging development model to be retired. Countries should apply an absolute moratorium on any further conversion of [natural] forests [to industrial plantations] — whether technically ‘legal’ or ‘illegal.’“
COP-26: Amazonia’s Indigenous peoples are vital to fighting global warming (commentary)
- The United Nations Climate Change summit, the 26th conference of the parties (COP-26), held in Glasgow Scotland through November 12, is important both for the future of the global climate and for Amazonian Indigenous peoples.
- Uncontrolled climate change threatens the Amazon forest on which Indigenous peoples depend, and Indigenous peoples in turn have an important role as guardians of the forest.
- Decisions on how international funds intended to avoid greenhouse gas emissions are used represent both opportunities and risks for the climate, for the forest, and for Indigenous peoples.
- Indigenous voices need to be heard at COP-26, as empowered stakeholders threatened by climate change, and for the invaluable traditional wisdom these peoples can contribute to global warming solutions. This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
As fossil fuel use surges, will COP26 protect forests to slow climate change?
- Despite the world’s commitment in Paris in 2015 to hold back the tide of global warming, carbon emissions continue rising, while impacts are rapidly escalating as heat waves, drought and extreme storms stalk the world’s poorest and richest nations — bringing intensified human misery and massive economic impacts.
- Once viewed optimistically, nature-based climate solutions enshrined in Article 5 of the Paris Agreement (calling for protections of carbon-storing forests, peat bogs, wetlands, savannas and other ecosystems) is now threatened by politics as usual, and by the unabated expansion of agribusiness and extraction industries.
- As world leaders gather in Scotland for the COP26 climate summit, scientists and advocates are urging negotiators to at last finalize comprehensive effective rules for Article 5, which will help assure “action to conserve and enhance, as appropriate, sinks and reservoirs of greenhouse gases … including forests.”
- Over the first two weeks in November at COP26, the vision and rules set at Paris are to be settled on and fully implemented; John Kerry, co-architect of the Paris accord and President Joe Biden’s climate envoy, calls this vital COP the world’s “last best chance” to finally move beyond mostly empty political promises into climate action.
Forest biomass-burning supply chain is producing major carbon emissions: Studies
- U.S., U.K., and E.U. policymakers are failing to count the carbon emissions cost of the forest biomass industry, according to two new first-of-their-kind studies. Though biomass burning is legally classified as carbon neutral, the research found that none of the parties involved is counting emissions generated along the supply chain.
- One study estimated that wood pellets made in the U.S. and burned in the U.K. led to 13-16 million tonnes of CO2 emissions in 2019 alone, equal to the emissions of up to 7 million cars. Should biomass burning be instituted by other nations in the near future, a process already underway, the result could be climatically catastrophic.
- The findings should be carefully considered as representatives of the world’s nations prepare to meet for the COP26 climate summit in Scotland, said experts. “These studies make clear that current energy policy doesn’t match the overwhelming science on the impacts of biomass,” said a member of the U.K.’s House of Lords.
- However, there are presently no official plans to address the forest biomass carbon accounting issue at COP26, though NGOs are investigating inroads to negotiations.
Inland mangroves reveal a tumultuous climatic past — and hint at our future
- A new study concludes that the presence of inland mangroves along a river in southern Mexico was the result of climate change-driven sea level rise during the Pleistocene Epoch, some 115,000 to 130,000 years ago.
- The researchers’ analysis of the genetic history of the mangrove trees suggests that they are closely related to trees found on the coastline, and sediments nearby are similar to those found in ocean environments.
- Publishing their work Oct. 12 in Proceedings of the National Academy of Sciences, the team notes that their research highlights the impacts of global climate change.
Extreme heat exposure in cities tripled in less than 35 years, study finds
- Exposure to dangerously high temperatures in cities nearly tripled between 1983 and 2016, according to a study that considered both warming and population growth.
- Cities are hotter than their surrounding areas because they are densely populated and tend to generate and trap more heat.
- The decade starting 2011 was the warmest in recorded history, and the proportion of the global population exposed to extreme heat is expected to multiply in the coming decades.
- Excessive warming of urbanized areas and the relentless influx of people points to an urgent need for policies that protect city residents, especially in developing countries.
Nitrogen: The environmental crisis you haven’t heard of yet
- The creation of synthetic fertilizers in the early 20th century was a turning point in human history, enabling an increase in crop yields and causing a population boom.
- But the overuse of nitrogen and phosphorus from those fertilizers is causing an environmental crisis, as algae blooms and oceanic “dead zones” grow in scale and frequency.
- Of the nine “planetary boundaries” that scientists say we must not cross in order to sustain human life, the boundary associated with nitrogen and phosphorus waste has been far surpassed, putting Earth’s operating system at risk.
- Global policymakers are beginning to slowly recognize the scale of the problem, as climate change threatens to make it worse. Absent major reforms to agribusiness practices, scientists are aiming to convince the world to reduce waste.
Researchers express alarm as Arctic multiyear sea ice hits record low
- Low sea ice concentration can create a misleading picture of sea ice health in the Arctic. Though extent is only at its 10th lowest since satellite records began in 1979, the waters north of Alaska this September are full of diffuse ice.
- Of great concern to scientists, the Arctic has lost 95% of its thick multiyear sea ice since 1985. Older, thicker ice acts as a buffer against future Blue Ocean Events, expected as early as 2035. A BOE would mark a year when most Arctic ice melts out in summer.
- It no longer takes a freak-weather year to reach near record-lows for extent or volume. 2020 saw a second-place finish in the record book, behind 2012.
In saving the ozone layer, we avoided even more intense global warming
- The Montreal Protocol, a 1987 agreement to stop using ozone-depleting chemicals, also helped combat climate change in more ways than one, a study published in Nature found.
- The group of synthetic gases called chlorofluorocarbons (CFCs) that deplete atmospheric ozone are also potent greenhouse gases, so phasing them out has protected the planet from warming above and beyond what we’re seeing today.
- At the same time, by preventing damage to plant life from harmful UV radiation, actions taken under the Montreal Protocol have safeguarded carbon reserves to the tune of 690 billion metric tons.
- The protocol’s success shows that collective action taken in time can make a difference in tackling global environmental challenges.
Burning forests to make energy: EU and world wrestle with biomass science
- A major political and environmental dispute is coming to a boil in the run-up to COP26 in Scotland this November, as the EU and the forestry industry push forest biomass (turning trees into wood pellets and burning them to make electricity), claiming the science shows biomass is sustainable and produces zero emissions.
- Forest advocates and many scientists sit squarely on the other side of the argument, providing evidence that biomass burning is destructive to forests and biodiversity, is dirtier than coal, and destabilizing for the climate. Moreover, they say, the carbon neutrality claim is an accounting error that will greatly increase carbon emissions.
- These views collided in July when the European Commission called for only minor revisions to its legally binding Renewable Energy Directive (REDII) in regard to biomass policy as part of the EU Green Deal. Critics say the plan, if approved by the EU Parliament in 2022, will fail to protect global forests from the wood pellet industry.
- Here, Mongabay offers a review of the science on both sides of the biomass debate, summarizing key studies and reports, and providing links to primary sources for enhanced insight into these complex issues. The EU decision to include wood pellets as part of its clean energy mix could help shape global biomass policy at COP26.
Soil and its promise as a climate solution: A primer
- We know that soil feeds plants, but do we know how it got there in the first place? Soil forms via the interaction of five factors: parent material, climate, living beings, a land’s topography, and a “cooking” time that occurs on a geologic scale. Variations in these 5 factors make the world’s soils unique and extremely diverse.
- Soil acts as a carbon sink in the global carbon cycle because it locks away decomposed organic matter. But deforestation, various agricultural practices, and a changing climate are releasing it back into the atmosphere and oceans as carbon dioxide, resulting in an imbalance in global carbon budgets
- Tropical soils and permafrost hold the most soil carbon out of other biomes, making them conservation and research priorities in soil-centered climate solutions.
- Reforestation of previously forested lands is a viable solution to return carbon belowground, but it is not a fix-all. Changing industrial agricultural practices and giving high-carbon storage areas conservation status are key steps toward harnessing the soil’s carbon storage power.
Humans’ role in climate warming ‘unequivocal,’ IPCC report shows
- The greenhouse gases humans have released into the atmosphere over the past 100 to 150 years has led to a 1.1°C (2°F) rise in global temperatures, according to the Intergovernmental Panel on Climate Change, or IPCC.
- The authors of the IPCC’s latest report use the strongest language yet to connect human activity to climate change, calling the link “unequivocal.”
- The report draws on the findings of thousands of studies, pointing to the need to cut CO2 emissions immediately while also suggesting that many of the impacts of climate change are irreversible.
- This report focuses on the science behind climate change and will be combined with two subsequent reports on the adaptation and vulnerability to the impacts of climate change and ways to mitigate its effects to produce the IPCC’s sixth assessment, scheduled for publication in September 2022.
New study says changes in clouds will add to global warming, not curb it
- Best estimates for global temperature increases due to a doubling of atmospheric CO2 since the start of the industrial era are between +1.5C and +4.5C. A major reason for this huge range of uncertainty is how clouds will perform in a warmed world, with some modelers saying clouds will help cool the planet, while the majority say clouds will further warm it.
- Clouds add immense uncertainty to climate models because they contain so many variables (including altitude, size, turbulence, amount of ice crystals, quantity and particle chemistry), and also because they don’t fit neatly inside the global grid cell system that modelers use to estimate warming.
- A new study used a machine learning model to bypass previous cloud modeling problems. The researchers concluded that a doubling of atmospheric CO2 will most likely lead to a 3.2C (5.76F) global temperature increase, almost exactly in the middle of the range estimated by the majority of current U.N. Intergovernmental Panel on Climate Change models.
- Researchers within and outside the study agree more data and research is needed to confirm or alter these results.
A world of hurt: 2021 climate disasters raise alarm over food security
- Human-driven climate change is fueling weather extremes — from record drought to massive floods — that are hammering key agricultural regions around the world.
- From the grain heartland of Argentina to the tomato belt of California to the pork hub of China, extreme weather events have driven down output and driven up global commodity prices.
- Shortages of water and food have, in turn, prompted political and social strife in 2021, including food protests in Iran and hunger in Madagascar, and threaten to bring escalating misery, civil unrest and war in coming years.
- Experts warn the problem will only intensify, even in regions currently unaffected by, or thriving from the high prices caused by scarcity. Global transformational change is urgently needed in agricultural production and consumption patterns, say experts.
Cerrado desertification: Savanna could collapse within 30 years, says study
- Deforestation is amplifying climate change effects in the Brazilian Cerrado savanna biome, making it much hotter and drier. Researchers observed monthly increases of 2.24°C (4.03°F) in average maximum temperatures between 1961 and 2019. If this trend persists, temperature could be 6°C (10.8°F) higher in 2050 than in 1961.
- Cerrado air moisture is decreasing partly due to the removal of trees, which bring water up from as much as 15 meters (nearly 50 feet) underground to carry on photosynthesis during the dry season. Replacement of native vegetation by crops also reduces the absorption of sunlight by wild plants and leads to an increase in temperature.
- Even dew, the only source of water for smaller plants and many insects during the dry season, is being reduced due to deforestation and deepening drought. The demise of pollinators that rely on dew may prompt a cascading effect adversely impacting the biome’s biodiversity, which could collapse in the next 30 years.
- The Cerrado is often called Brazil’s “water tank,” as it is the source of eight of 12 Brazilian river basins. Its looming biome collapse and deepening drought mean less water for rural and urban populations and for agriculture. Low flows in rivers will also affect hydropower, likely causing energy shortages.
Record heat waves are a taste of what’s to come under a changing climate
- A new study suggests that record-shattering heat events will become more frequent and more intense as the world continues to warm due to human-induced climate change.
- In a high-emissions scenario, the study suggests extreme heat waves will be two to seven times more probable between 2021 and 2050, and 21 times more probable between 2051 and 2080.
- If emissions can be curbed, however, and global temperatures do not exceed 2°C (3.6°F) above pre-industrial levels, this would help reduce extreme heat events.
Lessons from the 2021 Amazon flood (commentary)
- In June 2021, the annual flood season in the western and central Amazon reached record levels, and dramatic scenes of inundated homes, crops and city streets captured attention beyond Amazonia. This event provides lessons that must be learned.
- The high flood waters are explained by climatological forces that are expected to strengthen with projected global warming. Damaging floods represent just one of the predicted impacts in Amazônia under a warming climate.
- The administration of Brazilian President Jair Bolsonaro must change its current denialist positions on global warming and its policies that encourage deforestation. The Amazon forest must be maintained for many reasons in addition to its role in avoiding climate change.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Amazon and Cerrado deforestation, warming spark record drought in urban Brazil
- Southern and central Brazil are in the midst of the worst drought in nearly 100 years, with agribusiness exports of coffee and sugar, and the production of hydroelectric power, at grave risk.
- According to researchers, the drought, now in its second year, likely has two main causes: climate change, which tends to make continental interiors both hotter and drier, and the deforestation of the Amazon rainforest and Cerrado savanna biomes.
- Deforestation has caused the loss of almost half of the Cerrado’s native vegetation, which helps hold vast amounts of water underground, maintaining aquifers that supply the nation’s rivers with water. In the Amazon, rainforest loss is preventing billions of tons of water vapor from reaching the atmosphere.
- President Jair Bolsonaro acknowledges neither climate change nor deforestation as sources of the drought, but attributes it instead to the country and himself being “unlucky.” The administration’s drought response so far is to reactivate fossil-fuel power plants, which pollute heavily and are costly to operate.
Hotter and drier: Deforestation and wildfires take a toll on the Amazon
- Drought and high temperatures amplify the destructive effects of deforestation and wildfires.
- Across the Amazon Basin, tree species adapted to drier conditions are becoming more prevalent, and in the Central Amazon, savannas have replaced floodplain forests in just a few decades.
- While deforestation remains a main concern, the impacts of forest degradation are becoming increasingly important.
Rising temperatures further threaten already endangered African wild dogs
- Researchers examined three populations of African wild dogs in Botswana, Kenya and Zimbabwe to understand if high heat correlates with increased mortality.
- In two out of the three sites, there was a strong relationship between extreme temperatures and increased mortality, with intentional human killings, snare traps, road fatalities, and disease transmission from domesticated dogs responsible for 44% of the deaths.
- The researchers say high heat is pushing both wild dogs and pastoralists out of their typical grounds, creating a higher likelihood of human-wildlife conflict and mortalities for the dogs.
As Arctic warms, scientists wrestle with its climate ‘tipping point’
- A leaked version of the newest science report from the U.N. Intergovernmental Panel on Climate Change warns of looming, potentially catastrophic tipping points for Arctic sea ice melt, tundra thaw, savannification of the Amazon rainforest, and other planetary environmental thresholds beyond which recovery may be impossible.
- But what are tipping points, and how does one pinpoint what causes them, or when they will occur? When studying a vast region, like the Arctic, answering these questions becomes dauntingly difficult, as complex positive feedback loops (amplifying climate warming impacts) and negative feedback loops (retarding them) collide with each other.
- In the Arctic, one working definition of a climatic tipping point is when nearly all sea ice disappears in summer, causing a Blue Ocean Event. But attempts to model when a Blue Ocean Event will occur have run up against chaotic and complex feedback loop interactions.
- Among these are behaviors of ocean currents, winds, waves, clouds, snow cover, sea ice shape, permafrost melt, subarctic wildfires, aerosols and more, with many interactions still poorly understood. Some scientists say too much focus is going to tipping points, and research should be going to the “radical uncertainty” of escalating extreme local events.
Reforestation done right, from Haiti to Honduras and Ho Chi Minh City
- Local communities around the world are replanting their forests, and on today's episode of the Mongabay Newscast we take a look at why that's so important to combating climate change and building a sustainable future for life on Earth.
- Our first guest is Erin Axelrod, project director for Trees For Climate Health, who tells us about the nearly 40 community-based reforestation initiatives the program has funded based on its "right tree, right place, right community" approach.
- We also speak with freelance journalist and Mongabay contributor Mike Tatarski, who tells us about Vietnam's plans to plant a billion trees by 2025 and the NGOs in the country that are working to make tree-planting more community-centered and sustainable both economically and environmentally.
The science of forest biomass: Conflicting studies map the controversy
- A major political and environmental dispute is heating up as the forestry industry and governments promote forest biomass — cutting trees, turning them into wood pellets, and burning them to make electricity. They claim the science shows biomass to be sustainable, with the energy produced resulting in zero emissions.
- Forest advocates and many researchers sit squarely on the other side of the argument, providing evidence that forest biomass is destructive to forests and biodiversity, is dirtier than coal, and destabilizing for the climate. Moreover, they say, the carbon neutrality claim is an error that will greatly increase carbon emissions.
- These diverging viewpoints are colliding this week as the European Commission wrangles with revisions to its legally binding Renewable Energy Directive (REDII), with recommendations to the European parliament due this Wednesday, July 14, Analysts say the EU rules counting biomass as carbon neutral are unlikely to change.
- In this exclusive story, Mongabay provides a review of the science on both sides of the forest biomass debate, summarizing key studies and reports, and providing links to these primary sources to help readers decide for themselves.
As Arctic melt sets early July record, hard times lie ahead for ice: Studies
- Arctic sea ice fell to its lowest extent on record for this time of year on July 5, even though the spring had so far been relatively cool and stormy — conditions that, in the past, would have protected the ice.
- Three new studies help explain why. One found that increasing air temperatures and intrusion of warm water from the North Atlantic into the Barents and Kara Seas — a climate change-driven process known as Atlantification — are overpowering the ice’s ability to regrow in winter.
- Another study found that sea ice in coastal areas may be thinning at up to twice the pace previously thought. In three coastal seas — Laptev, Kara, and Chukchi — the rate of coastal ice decline increased by 70%, 98%, and 110% respectively when compared to earlier models.
- A third study found accelerated sea ice loss in the Wandel Sea, pointing to a possible assault by global warming on the Arctic’s Last Ice Area — a last bastion of multi-year sea ice which stretches from Greenland along the Canadian Arctic Archipelago. Combined, this research shows Arctic ice may be in worse trouble than thought.
Playing the long game: ExxonMobil gambles on algae biofuel
- Algae biofuel initially looked promising, but a few key problems have thwarted major research efforts, including development of a strain of algae able to produce plentiful cheap fuel, and scaling up to meet global energy demand.
- Other alternative energy solutions, including wind and solar power, are outpacing algae biofuel advances.
- Much more investment in money and time is needed for algae biofuel to become viable, even on an extended timeline out to mid-century. While big players like Shell and Chevron have abandoned the effort, ExxonMobil continues work.
- In 2017, ExxonMobil, with Synthetic Genomics, announced they had used CRISPR gene-editing technology to make an algal strain that could pave the way to a low-carbon fuel and a sustainable future. But many environmentalists met the claim with skepticism, suspecting greenwashing.
Biofuel in Mexico: Uphill battle against bureaucracy, organized crime
- Biofuels based on pressed plant oils, and made especially from used cooking oil, could help Mexico’s public transport sector transition to a cleaner and climate-friendly energy era, according to researchers and industry entrepreneurs.
- But there is a lack of government regulatory support, while the nation’s new president is betting on fossil fuels and neglecting biodiesel options and nature-based climate solutions.
- As a result, small biodiesel producers have to operate in a legal gray zone, while industry entrepreneurs are held back in the development of the technology and the market.
- Mexico isn’t alone: Many nations large and small are struggling with hurdles imposed by fossil fuel-friendly governments and a lack of supportive regulations to create a level playing field for the rapid development and deployment of biodiesel and other climate-friendly alternative energy solutions.
Converting biowaste to biogas could power cleaner, sustainable Earth future
- Biogas made from organic materials — including food and agricultural waste, and animal or human manure — is a renewable, sustainable, affordable and inclusive energy alternative becoming increasingly available to households, farms, municipalities and nations.
- Converting biowaste into biogas, via anaerobic digestion technology, is a strategy that could contribute to multiple U.N. Sustainable Development Goals and the Paris climate agreement. Biodigesters are already in use to meet a range of energy needs around the world.
- Current limiting factors to the sector’s growth include technical and adaptive challenges, lack of awareness in many regions, and unsupportive policy instruments that can discourage biogas adoption.
- Ahead of COP26, the critically important U.N. climate meeting coming this November, the World Biogas Association is urging governments to integrate biogas into their Nationally Determined Contributions — their voluntary emissions reduction targets, as agreed to under the Paris Agreement.
Forest loss in mountains of Southeast Asia accelerates at ‘shocking’ pace
- Southeast Asia is home to roughly half of the world’s tropical mountain forests, which support massive carbon stores and tremendous biodiversity, including a host of species that occur nowhere else on the planet.
- A new study reveals that mountain forest loss in Southeast Asia is accelerating at an unprecedented rate throughout the region: approximately 189,000 square kilometers (73,000 square miles) of highland forest was converted to cropland during the first two decades of this century.
- Mountain forest loss has far-reaching implications for people who depend directly on forest resources and downstream communities.
- Since higher-elevation forests also store comparatively more carbon than lowland forests, their loss will make it much harder to meet international climate objectives.
Earth tipping points could destabilize each other in domino effect: Study
- A new risk analysis has found that the tipping points of five of Earth’s subsystems — the West Antarctic Ice Sheet, the Greenland Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), the El Niño–Southern Oscillation (ENSO) and the Amazon rainforest — could interact with each other in a destabilizing manner.
- It suggests that these changes could occur even before temperatures reach 2°C (3.6°F) above pre-industrial levels, which is the upper limit of the Paris Agreement.
- The interactions between the different tipping elements could also lower critical temperature thresholds, essentially allowing tipping cascades to occur earlier than expected, according to the research.
- Experts not involved in the study say the findings are a significant contribution to the field, but do not adequately address the timescales over which these changes could occur.
Cleaning up Cambodia’s kitchens could curb deforestation, climate change
- NGOs and companies across Cambodia are taking action in response to the mass use of charcoal and forest biomass in household and restaurant kitchens countrywide. The shift away from these polluting fuel sources to cleaner energy alternatives is being sparked by health and environmental concerns.
- Education is a key strategy for implementing the shift away from charcoal and wood, as their use is ingrained in the culture, with many Cambodians saying food doesn’t taste as good when cooked with other fuels.
- One innovative solution is turning the country’s coconut husks into “green charcoal,” which is already earning the nation recognition for being a global leader within the sustainable charcoal sector.
- Cambodia’s farmers are also moving away from using forest biomass for energy, and are instead utilizing biodigesters to turn household and farm waste into biogas for cooking and to make organic fertilizer.
Rush to turn ‘black diamonds’ into cash eats up Uganda’s forests, fruits
- As recently as 2018, only a little over 42% of Ugandans had access to electricity — many were too poor to afford it. As of 2016-17, 90% of all households burned wood fuel for cooking, with just 15.5% using charcoal in rural areas, but 66.4% of urban households using it.
- Those using charcoal account for roughly 23% of the country’s total population, which means that some 10.7 million citizens in a nation of 46.8 million rely on charcoal to cook their meals, based on recent U.N. data.
- Charcoal producers are working hard to meet this exploding demand, degrading and depleting the nation’s forest reserves, and now buying up fruit trees on private lands to make into briquettes. Many charcoal producers lack the licenses required by the government, so are cutting trees and making charcoal illegally.
- The surging charcoal industry is destroying Uganda’s forests and biodiversity, while briquette burning is also causing respiratory and other health problems, and its carbon emissions are adding significantly to global climate change.
Forest advocates press EU leader to rethink views on biomass and energy
- EU officials are currently working to finalize REDII renewable energy policy revisions and amendments by mid-July for EU parliamentary review. One component of that review is to determine whether forest biomass burning will continue to be considered carbon neutral by the 27 EU member states.
- Current science is clear: burning forest biomass to make energy is not carbon neutral, and the burning of wood pellets is dirtier per unit of electricity than burning coal. But the forestry industry and EU continue defending biomass, prompting an open letter from forest advocates harpooning the policy.
- In the leadup to the updated REDII policy revision proposals, European Commission Exec. VP Frans Timmermans says he truly values forests, but simultaneously believes that cutting them down and burning them to make electricity remains viable climate policy. More than 50% of the EU’s current wood harvest is being burned for energy.
- “Ecocide threatens the survivability of our forests. I certainly don’t underestimate the challenges we face, but still, I believe [burning forest] biomass can play a very useful role in the energy transition,” says Timmermans.
Scientists call for solving climate and biodiversity crises together
- A new report from United Nations’ Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) highlights the importance of confronting climate change and biodiversity loss together.
- Global climate change and the unprecedented loss of species currently underway result from a similar suite of human-driven causes, the report’s authors write.
- As a result, solutions that take both issues into account have the best chance of success, they conclude.
Can Biden’s 30×30 plan put U.S. on a positive conservation track?
- On today's episode of the Mongabay Newscast, we discuss the 30x30 conservation plan recently released by the administration of US President Joe Biden and its potential to transform the way the US conserves its natural resources.
- Joe Walston, executive vice president of global conservation for the Wildlife Conservation Society, tells us that the Biden 30x30 plan has been welcomed by environmentalists, even though many important details of the plan still need to be hammered out, and that it sends a signal to the rest of the world that the US is once again looking to lead the world in conservation.
- Sarah Derouin, a Mongabay contributor and a producer of the weekly radio show and podcast "Big Picture Science," tells us about two agroforestry programs that are already changing the way food is produced in the US and how agroforestry might help meet the 30x30 targets.
The key to averting environmental catastrophe is right beneath our feet
- Billions of years ago, the first soils served as a cradle for terrestrial life. Today, the land beneath our feet underpins a multitrillion-dollar, global agricultural industry and provides food for nearly 8 billion humans, along with countless wild and domestic species. But soils are in global crisis.
- We are now living in the “danger zone” for four of the nine planetary boundaries: climate change, biodiversity, land-use change, and biogeochemical flows. All four are intimately linked to soil health. Soils hold 80% of all the carbon stored on land.
- Deteriorating soil health is already gravely impacting lives and livelihoods. Land degradation due to human activities costs around 10% of global gross product. When combined with climate change effects, soil degradation could reduce crop yields by 10% globally by 2050.
- There is an inevitable delay between recognizing global problems and enacting solutions, and seeing the resulting boost to ecosystem services. That’s why we must act now if we are to leverage soil ecosystems in the fight against disastrous global environmental change.
Indonesian president slammed for ‘wait-and-see’ approach on climate action
- During last month’s climate summit of world leaders, top emitters announced more ambitious climate targets in a bid to combat climate change.
- Missing from that list was Indonesia, whose president, Joko Widodo, instead called on industrialized countries to set an example for other nations to follow.
- Climate and policy experts in Indonesia say his failure to announce a bold target for achieving net-zero emissions is a missed opportunity for Indonesia to show global leadership based on its success in reducing deforestation.
- They also criticized a government proposal, not yet officially endorsed by the president, to achieve carbon neutrality by 2070 — 20 years later than most other major emitters.
Ever-evolving Montreal Protocol a model for environmental treaties
- Since the Montreal Protocol was signed in 1987, countries have been phasing out most ozone-damaging chemicals, helping protect the Earth’s protective shield. In this exclusive Mongabay interview, Megumi Seki, Acting Executive Secretary of the UN Environment Programme’s Ozone Secretariat, reviews the history and future of the landmark treaty.
- The Montreal Protocol phase-down has also helped prevent further climate warming. But the HFCs — replacement gases employed by industry as refrigerants and for other uses — while not harmful to the ozone layer, have been found to be powerful greenhouse gases that contribute to climate change.
- In 2016, national delegates agreed on the Kigali Amendment to the Montreal Protocol, which calls for cutting the production and use of HFCs by 80–85% by the late 2040s. The amendment entered into force at the start of 2019, with the goal of avoiding additional warming by up to 0.4°C (0.72 °F) by the end of the century.
- The early steps of the Montreal Protocol, and its ongoing adjustments including the Kigali Amendment, provide vital clues as to how to effectively negotiate, implement, update, and succeed in moving forward with other future environmental treaties.
The HFC challenge: Can the Montreal Protocol continue its winning streak?
- Since the Montreal Protocol was signed in 1987, countries have phased out most of the ozone-damaging gases, but their replacements, the HFCs, are powerful greenhouse gases that contribute to climate change.
- In 2016, national delegates agreed on the Kigali Amendment to the Montreal Protocol, which calls for cutting the production and use of HFCs by 80–85% by the late 2040s. The amendment entered into force at the start of 2019, with the goal of avoiding additional warming by up to 0.4°C (0.72 °F) by the end of the century.
- The future success of the Kigali Amendment faces several challenges, including countries inaccurately estimating their emissions of HFCs, the need for affordable alternatives, and the fact that the major producers of HFCs (China, the United States and India) have not yet signed the treaty.
- Scientists and policymakers continue to address these challenges, with the U.S. and China having recently announced their intent to ratify the treaty. Also, the U.S. this week signaled its commitment to aggressively cutting the use and production of HFCs via a new, proposed Environmental Protection Agency rule.
Reversing warming quickly could prevent worst climate change effects: Study
- Irreversible and catastrophic environmental tipping points could still be avoided, even if we exceed global emission reduction targets — provided the world is able to reverse overshoot quickly, according to researchers.
- Simple mathematical models of four earth system tipping elements reveal a lag between overshooting the threshold and irreversible change. “Slow-onset” elements like icecap melt operate on century-long timescales, while Amazon dieback could pass a point of no return in just decades.
- However, experts warn that the models fail to take interactions between different tipping elements into account, which could shorten the amount of time a threshold can be overshot. Many of these interactions are poorly understood, making them difficult to include in climate models.
- Researchers say these results show there is still good reason to take action to mitigate global warming, even if we do overshoot the Paris Agreement target of 1.5°C. Some warn the study results could be used as an excuse to tolerate further delays on global climate action.
Leaders make bold climate pledges, but is it ‘all just smoke and mirrors?’: Critics
- Forty nations — producers of 80% of annual carbon emissions — made pledges of heightened climate ambition this week at U.S. President Joe Biden’s Leaders Summit on Climate. But as each head of state took to the podium, climate activists responded by pointing to the abysmal lack of action by those nations.
- As the U.S. promised to halve its emissions by 2030, advocates noted the lack of policies in place to achieve that goal, and the likelihood of intense Republican political resistance. China promised at the summit to eliminate coal plants, but 247 gigawatts of coal power is currently in planning or development stages there.
- The UK, EU, Japan, and South Korea all pledged to do more, but all are committed to burning forest biomass to replace coal — a solution relying on a longstanding carbon accounting error that counts forest biomass as carbon neutral, though scientists say it produces more emissions than coal per unit of electricity made.
- “This summit could be a critical turning point in our fight against climate change, but we have seen ambitious goals before and we have seen them fall flat. Today’s commitments must be followed with effective implementation, and with transparent reporting and accurate carbon accounting,” said one environmental advocate.
As climate summit unfolds, no Biden-Bolsonaro Amazon deal forthcoming
- The United States and Brazil have been conducting closed door negotiations to broker an Amazon rainforest protection agreement — with the U.S. and other nations tentatively to provide significant funding, and Brazil possibly agreeing to pragmatic measures to end deforestation.
- However, as the global Climate Leaders Summit progressed today, it became apparent that those talks are likely stalemated, with no deal announced, nor likely anytime soon.
- Brazilian President Jair Bolsonaro has made it clear that Amazon conservation is dependent on a big financial investment by the United States. However, Amazon deforestation continued soaring through March, even as critics offered substantial proof Brazil is insincere in its environmental commitments.
- For example, new federal rules make it nearly impossible to collect fines for environmental crimes. Also, Brazil has made suspect adjustments to its Paris Climate Agreement carbon reduction targets, allowing it to meet its goals on paper, even as it continues cutting down forests and releasing greenhouse gases.
With British Columbia’s last old-growth at risk, government falters: Critics
- British Columbia’s ruling New Democratic Party last autumn pledged to conserve 353,000 hectares (1,363 square miles) of old-growth forest. But so far, the NDP has largely failed to act on this pledge, even as forestry companies rush to procure and cut old-growth in the Canadian province.
- Unless the government acts quickly on its commitment, BC’s last old-growth could be gone in as little as 5-10 years say some forest ecologists. In addition, intense logging could mean that Canada is not going to meet its Paris Climate Agreement carbon-reduction goals.
- While the NDP promised a new policy boosting forest perseveration over forestry, critics say that — despite its rhetoric — the government continues to prop up an industry in decline to help rural communities in need of jobs.
- While it’s not now cutting BC old-growth, activists worry over the acquisition by U.K. Drax Group of BC’s largest wood pellet producer, Pinnacle Renewable Energy and its seven BC pellet mills. Drax provides up to 12% of the U.K.’s energy at the world’s largest pellet-burning plant. Its BC exports to Japan are also expected to grow.
Though humanity exceeds key ‘planetary boundaries’ there are many solutions
- On this episode of the Mongabay Newscast, we speak with two recent contributors to our "Covering the Commons" special reporting project who wrote pieces that deal with the concept of Planetary Boundaries and how we can build a more sustainable future.
- Claire Asher tells us about her recent article detailing the nine Planetary Boundaries, the four environmental limits we've already exceeded, and the chances 2021 offers us to make transformative change.
- Andrew Willner discusses his recent article on how a "New Age of Sail" might soon transform the international shipping industry, the sixth-largest source of carbon emissions in the world.
The nine boundaries humanity must respect to keep the planet habitable
- All life on Earth, and human civilization, are sustained by vital biogeochemical systems, which are in delicate balance. However, our species — due largely to rapid population growth and explosive consumption — is destabilizing these Earth processes, endangering the stability of the “safe operating space for humanity.”
- Scientists note nine planetary boundaries beyond which we can’t push Earth Systems without putting our societies at risk: climate change, biodiversity loss, ocean acidification, ozone depletion, atmospheric aerosol pollution, freshwater use, biogeochemical flows of nitrogen and phosphorus, land-system change, and release of novel chemicals.
- Humanity is already existing outside the safe operating space for at least four of the nine boundaries: climate change, biodiversity, land-system change, and biogeochemical flows (nitrogen and phosphorus imbalance). The best way to prevent overshoot, researchers say, is to revamp our energy and food systems.
- In 2021, three meetings offer chances to avoid planetary boundary overshoot: the Convention on Biological Diversity meeting in Kunming, China; the U.N. Climate Summit (COP26) in Glasgow, U.K.; and the U.N. Food Systems Summit in Rome. Agreements with measurable, implementable, verifiable, timely and binding targets are vital, say advocates.
As Arctic sea ice hits annual maximum, concern grows over polar ice loss: Studies
- Arctic sea ice reaches its annual maximum extent in March. But while ice extent is high this year, scientists are far more concerned by the drastic loss of sea ice volume, which continues its steady decline.
- A new study has documented drastic ice loss in both the north and south polar regions; scientists found that the single biggest reduction came from Arctic sea ice — the Earth lost 7.6 trillion metric tons of it in the last three decades.
- Another new study shows that the last bastion of old, thick multiyear ice in the Arctic, north of Greenland and Ellesmere Island, is diminishing as the stability of the Nares ice arches declines — blockages which work like a cork in a bottle to stop multiyear ice from flowing out into the Atlantic.
- Meanwhile, researchers warn about the urgent need for new Arctic monitoring satellites. Currently there is just one in operation, the DMSP-F18 satellite, and it has already been in orbit more than a decade. Its failure could leave researchers blind and disrupt an Arctic ice database continuous back to 1978.
New age of sail looks to slash massive maritime carbon emissions
- If ocean shipping were a country, it would be the sixth-largest carbon emitter, releasing more CO2 annually than Germany. International shipping accounts for about 2.2% of all global greenhouse gas emissions, according to the U.N. International Maritime Organization.
- But change is on the way. Wind, solar electric, and hydrogen-powered ships offer innovative low- or no-carbon alternatives to fossil fuel-powered cargo vessels, with wind about to make a huge comeback in shipping, say experts. New experimental sail designs include hard sails, rotating vertical cylinders, and even kites.
- Today, startup companies like Fair Transport (with its retrofitted wooden vessels Tres Hombres and Nordlys); modest sized proof-of-concept firms, with purpose-built vessels like Grain de Sail; and large cargo ship retrofits and purpose-built vessels like Neoline’s new large cargo vessels, are starting to address CO2 emissions.
- Through the late 1940s, huge steel sailing ships carried cargos on some ocean routes. By 2030 — less than 100 years since the end of the last great era of sail — fossil fuel-powered cargo vessels may give way to high- and (s)low-tech sailing ships thanks to a revolution in energy technology, that reduces shipping costs with less emissions.
Can agroecology feed the world?
- Agroecology is an approach to sustainable farming that is quickly spreading around the globe, transforming the way food is produced.
- We're joined on this episode of the Mongabay Newscast by food systems expert Anna Lappé who discusses why the idea that agroecology is a "low yield" practice is a myth, and just how important the growing adoption of agroecological practices around the globe is to the future of life on Earth.
- We're also joined by behavioral scientist Philipe Bujold of the NGO Rare’s Center for Behavior & the Environment, who tells us about the organization's Lands for Life program, which employs behavioral science to encourage smallholder farmers in Colombia to adopt more sustainable, climate-friendly farming practices.
Dutch to limit forest biomass subsidies, possibly signaling EU sea change
- The Dutch Parliament in February voted to disallow the issuing of new subsidies for 50 planned forest biomass-for-heat plants, a small, but potentially key victory for researchers and activists who say that the burning of forests to make energy is not only not carbon neutral, but is dirtier than burning coal and bad climate policy.
- With public opinion opposing forest biomass as a climate solution now growing in the EU, the decision by the Netherlands could be a bellwether. In June, the EU will review its Renewable Energy Directive (RED II), whether to continue allowing biomass subsidies and not counting biomass emissions at the smokestack.
- Currently, forest biomass burning to make energy is ruled as carbon neutral in the EU, even though a growing body of scientific evidence has shown that it takes many decades until forests regrow for carbon neutrality to be achieved.
- The forestry industry, which continues to see increasing demand for wood pellets, argues that biomass burning is environmentally sustainable and a viable carbon cutting solution compared to coal.
Deforestation in Indonesia hits record low, but experts fear a rebound
- The deforestation rate in Indonesia last year fell by 75% to its lowest level since monitoring began in 1990, according to the government.
- Officials attribute this mainly to government policies such as moratoriums on clearing primary forests and issuing licenses for new oil palm plantations.
- Environmentalists say other factors contributed, including an unusually wet year, declining palm oil prices, and an economic slump that led to a slowdown in forest-clearing activity such as plantation expansion and logging.
- They’ve called on the government to keep aiming for even lower rates of deforestation, and cautioned against pursuing economic growth emulating Brazil’s deforestation-driven extractive model.
Corals are struggling, but they’re too abundant to go extinct, study says
- A study has found that most reef-building coral species are not in imminent danger of being wiped off the planet because they are abundant and occupy vast ranges.
- It looked at 318 species across 900 reefs in the Pacific Ocean, from Indonesia to French Polynesia, and found half a trillion coral colonies in the region.
- The study authors are calling for a revision of the IUCN Red List, according to which a third of all reef-building corals face some degree of extinction risk.
- At the same time the new research underlines the fact that local extinctions and the loss of ecological function are real and present threats.
Is ecosystem restoration our last/best hope for a sustainable future?
- On today's episode of the Mongabay Newscast, we take a look at the growing movement to restore degraded ecosystems worldwide. The decade of 2021 to 2030 has been declared the UN Decade on Ecosystem Restoration.
- Author Judith Schwartz joins us to discuss her 2020 book The Reindeer Chronicles: And Other Inspiring Stories of Working with Nature to Heal the Earth, which documents numerous restoration projects around the globe and highlights the ways the global ecological restoration movement is challenging us to reconsider the way we live on planet Earth.
- We're also joined by Tero Mustonen, president of an NGO based in Finland called the Snowchange Cooperative, who tells us about the group's Landscape Rewilding Programme, which is "rewilding" Arctic and Boreal habitats using Indigenous knowledge and science.
As Amazon forest-to-savanna tipping point looms, solutions remain elusive
- Leading scientists project that if an additional 3-8% of rainforest cover is lost in the Amazon, it may overshoot a forest-to-degraded-savanna tipping point. That shift could mean mega-drought, forest death, and release of great amounts of stored carbon to the atmosphere from southern, eastern and central Amazonia.
- Despite this warning, Brazilian Amazon deforestation hit an 11-year high in 2020. Government clampdowns on environmental crime greatly decreased deforestation in the past, but Brazil is now facing a political backlash led by President Jair Bolsonaro, resulting in agribusiness and mining expansion and deforestation.
- Market efforts to create incentives have been ineffective. A public-private plan to cut deforestation led by Mato Grosso state has not met its environmental targets, even as agricultural lands increased. Amazonas, Acre and Rondônia — Bolsonaro-aligned states — are pushing for the creation of a new agriculture frontier.
- Indigenous communities, because they’re the best land stewards, should be at the forefront of public policy to conserve the Amazon, say experts, but instead they face poverty and marginalization by the institutions responsible for securing their land rights. International response to the Amazon crisis has also lagged.
U.N. report lays out blueprint to end ‘suicidal war on nature’
- According to a new report from the United Nations Environmental Programme, the world faces three environmental “emergencies”: climate change, biodiversity loss, and air and water pollution.
- U.N. Secretary-General António Guterres said we should view nature as “an ally,” not a foe, in the quest for sustainable human development.
- The report draws on assessments that quantify carbon emissions, species loss and pollutant flows to produce what the authors call concrete actions by governments, private companies and individuals that will help address these issues.
500+ experts call on world’s nations to not burn forests to make energy
- Last week, more than 500 top scientists and economists issued a letter to leaders in the US, EU, Japan, South Korea, and the UK, urging them to stop harvesting and burning forests as a means of making energy in converted coal burning power plants.
- The burning of forest biomass to produce electricity has boomed due to this power source having been tolerated as carbon neutral by the United Nations, which enables nations to burn forest biomass instead of coal and not count the emissions in helping them meet their Paris Climate Agreement carbon reduction targets.
- However, current science says that burning forest biomass is dirtier than burning coal, and that one of the best ways to curb climate change and sequester carbon is to allow forests to keep growing. The EU and UK carbon neutrality designations for forest biomass are erroneous, say the 500 experts who urge a shift in global policy:
- “Governments must end subsidies… for the burning of wood…. The European Union needs to stop treating the burning of biomass as carbon neutral…. Japan needs to stop subsidizing power plants to burn wood. And the United States needs to avoid treating biomass as carbon neutral or low carbon,” says the letter.
Researchers urge better protection as wetlands continue to vanish
- Wetlands provide many benefits to ecological and human communities alike, from nutrients and nurseries to flood control and climate change mitigation.
- However, as much as 87% of the world’s wetlands has been lost over the past 300 years, with much of this loss happening after 1900.
- In response, nations banded together and in 1971 ratified the Ramsar Convention on Wetlands, an intergovernmental treaty designed to facilitate wetland conservation and sustainable use around the world.
- But 50 years on, researchers say the convention has not led to effective protection and wetlands continue to blink out.
Are biomass and hydropower ‘false’ climate solutions?
- On this episode of the Mongabay Newscast, we look at two energy-related technologies that are being promoted as climate solutions, biomass and hydropower, which might have unintended consequences that hamper their ability to supply clean energy and thus might not be sustainable solutions at all.
- Our first guest is Justin Catanoso, a professor at Wake Forest University and long-time Mongabay correspondent. Catanoso tells us about the loopholes in renewable energy policies that have allowed the biomass industry to flourish under the guise of "carbon neutrality," even though the burning of biomass for energy releases more carbon emissions than burning coal.
- We also speak with Ana Colovic Lesoska, a biologist by training who founded the Eko-Svest Center For Environmental Research in North Macedonia. Colovic Lesoska was instrumental in shutting down two large hydropower projects in her country's Mavrovo National Park, but there are still more than 3,000 new hydropower projects proposed in the Balkans. She tells us why hydropower is being adopted by Balkan countries and whether or not hydropower can be a climate solution at any scale.
Will new US EPA head continue his opposition to burning forests for energy?
- Under President Donald Trump the U.S. made moves toward legally enshrining the burning of forest biomass to make energy on an industrial scale as a national policy. That same policy has been embraced by the United Kingdom and European Union, helping them move toward a target of zero carbon emissions — at least on paper.
- However, the carbon neutrality label given to the burning of woody biomass to make energy, first proclaimed under the Kyoto Protocol, then grandfathered into the Paris Climate Agreement, has been found by science over the last decade to be more accurately characterized as a risky carbon accounting loophole.
- Current science says that carbon neutrality achieved from burning wood pellets would take 50-100 years to achieve, time the world doesn’t have to slash its emissions. Further, burning woody biomass is inefficient, and dirtier than coal.
- Michael S. Regan, President Biden’s choice for EPA head, wrestled with the problem of producing wood pellets for use as energy while leading North Carolina’s environmental agency. Now he’ll be contending with the issue on a national and possibly global scale. His past views on the topic are laid out in this story in detail.
New study warns that sea levels will rise faster than expected
- A new study has found that sea level rise may happen faster than current models project.
- The Intergovernmental Panel on Climate Change (IPCC) projects that the sea level will rise about a meter (39 inches) by the century’s end, but this study finds that estimate to be conservative.
- The results suggest that sea levels will rise about 25 centimeters (10 in) more per century if carbon emissions are not curbed and the Earth continues to heat up.
Seven financial firms key to rooting out deforestation, report finds
- Exchange-traded funds (ETFs) and index funds are some of the most popular investment tools available, popular among individual and institutional investors alike.
- Just a handful of asset management firms control between 60% and 70% of these funds, according to a recent report from the financial think tank Planet Tracker.
- Planet Tracker’s analysis found that $9.3 billion from ETFs is invested in a set of 26 companies engaged in the soybean trade and linked to deforestation.
- The report concludes that the financial firms in which ETFs and index funds are concentrated are critical in addressing financial support for deforestation.
Agroforestry, an ancient climate solution that boosts food production and biodiversity
- On today’s episode of the Mongabay Newscast, we speak with three different guests about why agroforestry is increasingly being implemented worldwide to address industrial agriculture’s contributions to the global environmental crises we’re facing as well as to create new livelihood opportunities and build food security for local communities.
- Agroforestry is the practice of incorporating woody perennials like trees and shrubs into a system with agricultural crops or livestock. It’s been practiced by indigenous peoples for thousands of years, and they are still perhaps the chief practitioners of it today.
- We speak with Mongabay's own Erik Hoffner, who edits Mongabay's ongoing coverage of agroforestry, as well as Sarah Lovell, who talks about agroforestry in the US, and Roger Leakey, who discusses agroforestry in the tropics.
Critical temperature threshold spells shorter lives for tropical trees
- Rising temperatures as a result of climate change are making tropical forests hotter, which translates into shorter life spans for tropical tree species, a new study shows.
- Tropical forests host about 50% of Earth’s biodiversity and 50% of its forest carbon stocks; their capacity to capture and store carbon depends on their health and longevity.
- The authors of the study warn that the shorter life span raises concerns about the future potential of forests to offset CO2 emissions from fossil fuel burning.
- They also warn that temperatures will keep rising in the near future — “even if we were to take drastic emissions reductions measures.”
Tropical forests can take the heat, study finds. Dryness? Not so much
- Researchers simulated extreme global warming conditions for tropical forests in the Biosphere 2 dome in the Arizona desert, cranking up the temperature to 40°C (104°F).
- To gauge the trees’ resilience, they looked at how well they continued to photosynthesize, and found that they could do so up to 38°C (100°F), which is 10°C (18°F) warmer than the average temperature in tropical forests today.
- However, the enclosed dome helped maintain humidity levels, whereas real-world warming would lead to drier air, and therefore greater loss of water from plants through transpiration.
- The researchers say the study nevertheless provides relevant information on the main threats to these ecosystems: the combination of a warmer world and a drier climate.
EU renewable energy policy subsidizes surge in logging of Estonia’s protected areas (commentary)
- European Union renewable energy subsidies are fueling a dramatic surge in the logging of protected forests in Estonia.
- The Estonian government has issued logging permits for 82,000 hectares of forest – the equivalent to 115,000 football fields – which have been designated protected habitats under Natura 2000.
- “As a result, intolerable pressure is being exerted on the forests that cover half our country, with even protected forests being clear-cut,” writes the vice-chairman of the Estonian Fund for Nature.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
