EV supply chain & transport need redesign, Mongabay podcast shows
Reducing transportation’s carbon footprint is not as easy as replacing internal combustion engine (ICE) cars with electric vehicles (EVs). Producing EVs and disposing their components have environmental and human rights impacts, which also need to be carefully considered and mitigated, Mongabay’s Mike DiGirolamo found in an episode of Mongabay Explores podcast in November. In this […]
Global warming hits hardest for those who can’t escape it
- The world’s most vulnerable people, including refugees, migrants and the poor, increasingly face threats related to climate change.
- Many lack the ability to move away from impacts like heat, flooding and landslides.
- A new study reveals a lack of data showing the causes of this involuntary immobility.
- Experts say governments and organizations can invest in low-cost interventions aimed at reducing suffering.
DRC’s Kinshasa could see deadly rain and floods every 2 years: Study
In early April, extreme rainfall and flooding in and around Kinshasa, the capital of the Democratic Republic of the Congo, killed at least 33 people. Such catastrophic rainfall events are predicted to hit Kinshasa every two years in today’s warming climate, according to a new rapid study by World Weather Attribution (WWA), a network of […]
Nature on the move: How conservation must adapt to survive
Resilience means getting through something — tough, messy, with losses, but surviving. So said Andrew Whitworth, executive director of Osa Conservation in Costa Rica, summing up a growing shift in conservation thinking. As the planet hurtles toward a future 3-5° Celsius (5.4-9° Fahrenheit) warmer by 2075, holding the line is no longer enough. The goal […]

In an ancient Javanese sultanate, coastal women battle climate fallout
- The coast of Demak district, the site of the first Islamic sultanate on the island of Java, has been inundated by the sea over decades owing to groundwater extraction and development.
- The erosion of human settlements is likely introducing new risks for women: “Our conclusion is that women and children, as well as poor families, including the elderly and disabled, are the most vulnerable,” a local legal aid nonprofit told Mongabay.
- Globally, around 90% of fish species are either fully exploited or overfished, and climate change is set to worsen the crisis by disrupting fish reproduction as oceans warm and acidify.
Diverse forests and forest rewilding offer resilience against climate change
- Recent studies from two long-running planted forest experiments in China and Panama find that increasing tree diversity in reforestation efforts can boost resilience in the face of climate change, among other benefits.
- Researchers elsewhere propose a “rewilding-inspired forestry” approach that aims to restore biodiversity, aid climate mitigation and bolster forest ecosystems — an approach that requires a significant shift from current forestry practices.
- However, scientists underline that while reforestation and forest rewilding can contribute to curbing climate change, they have their limits and must be combined with deep carbon emissions cuts and conservation of existing forests.

Many areas in the country’s northwest remain on […]
How is conservation preparing for a much hotter world? Experts share
- Fifty years from now, in 2075, the world will be considerably hotter, perhaps as much as 3-5° Celsius (4.5 to 9° Fahrenheit) above the pre-industrial average.
- Experts say we need to focus on building greater resilience into ecosystems now to help species get through the next half century.
- We should be protecting large landscapes, including altitudinal gradients, according to experts.
- We should also be focusing on good management, community relations, rewilding and restoration.
Honduras pays the climate cost as its forests disappear and storms rise
- Despite its high vulnerability to extreme weather events, Honduras continues to clear its forests, seen as one of its best protections against climate change and intensifying storms and hurricanes.
- Between 1998 and 2017, Honduras was the world’s second-most affected country by climate change.
- The biggest driver of deforestation in Honduras is shifting agriculture, responsible for nearly three-quarters of all tree loss, with cattle ranching being a top culprit.
- International organizations focusing on climate adaptation and mitigation are urging the Honduran government to do more to prioritize long-term preparedness, with the country recently making progress in that direction.

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.
Hotter weather threatens heart health, Australian study warns
Extreme heat is putting people in Australia at serious risk of heart problems and premature deaths, according to new research. As the climate warms, rising temperatures could more than double Australia’s burden of cardiovascular diseases by 2050, unless greenhouse gas emissions are reduced, and people take measures to adapt to the heat, researchers found. Cardiovascular […]
African forum on urban forests calls for greater access to green spaces
- Researchers policymakers, and civil society gathered at the African Urban Forest Forum in Johannesburg to discuss the role of urban forests in African cities.
- The forum centered on how trees can make cities more climate-resilient, providing more equitable access to green spaces, and finding sustainable financing strategy for urban forests.
- In a declaration at the end of the forum, participants called for greater collaboration to increase tree canopy cover in cities and address the combined challenges of rapid urbanisation, climate change and historical inequalities.
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.

BeeWalk, run by the Bumblebee Conservation Trust, is an annual standardized monitoring program, in which volunteers and partner organizations record […]
A tale of two cities: What drove 2024’s Valencia and Porto Alegre floods?
- In 2024, catastrophic floods occurred in the cities of Porto Alegre, Brazil, and Valencia, Spain. These two record floods number among the thousands of extreme weather events that saw records for temperature, drought and deluge shattered across the globe. Such horrors have only continued in 2025, with the cataclysmic wildfires in Los Angeles.
- Scientists have clearly pegged these disasters to carbon emissions and intensifying climate change. But a closer look at Porto Alegre and Valencia shows that other causes contributed to the floods and droughts there, and elsewhere on the planet — problems requiring nuanced but Earth-wide changes in how people live and society develops.
- Researchers especially point to the drastic destabilization of the world’s water cycle, which is increasingly bringing far too little precipitation to many regions for far too long, only to suddenly switch to too much rain all at once — sometimes a year’s worth in a single day, as happened in Valencia when 445.5 mm (17.5 inches) fell in 24 hours.
- The problem isn’t only CO2 emissions, but also local deforestation and hardened urban infrastructure that promote flooding. But what may be seriously underestimated is how large-scale destruction of forest, marshland and other vegetation is dangerously altering rainfall patterns, a theory proposed decades ago by a little-known Spanish scientist.
Flash floods, blackouts and a ‘sharknado’ as Cyclone Alfred lashes Australia

Collaboration, data and tracking move Africa’s Great Green Wall toward its goal
- After years of delays due to insufficient funding and prevailing conflicts, the Great Green Wall in the Sahel, aimed at preventing desertification, gained momentum with an accelerator program announced in 2021.
- As part of the accelerator, efforts are underway to address delays, improve monitoring progress of different projects that are part of the GGW initiative, track them by country, and evaluate their effectiveness, including building a new online database.
- GGW partners say they hope the harmonized monitoring and progress tracking can help sustain funding and realize the objectives of the ambitious initiative in the Sahel.
Vicuña poop creates biodiversity hotspots as glaciers retreat rapidly
- The vicuña, a wild relative of the llama, could help reestablish plants in barren areas where glaciers have melted, according to a recent study in the high Andes of Peru.
- As vicuñas tend to poop in the same places, they establish communal latrines where soils have much higher moisture, organic matter, nutrients and microorganisms than surrounding areas formerly covered by ice.
- Researchers say they believe these more nutrient-rich soil patches can speed up plant colonization by as much as a century and provide refuge for plant species moving uphill as temperatures increase.
- Peru is losing its glaciers at a worrying speed, with research pointing out that in the Central Andes, between 84% and 98% of their glaciers might disappear by 2050.
Researchers find two individuals of UK’s ‘loneliest bat’ species

World’s record heat is worsening air pollution and health in Global South
- 2024 was the hottest year on record, producing intense, long-lasting heat waves. Climate change-intensified extreme events last year included the formation of vast heat domes — areas of high pressure that stalled and persisted above continental land masses in Asia, Africa, South and North America, and Europe.
- Heat domes intensify unhealthy air pollution from vehicles, industry, wildfires and dust storms. When a heat wave gripped New Delhi, India, last summer, temperatures soared, resulting in unhealthy concentrations of ground-level ozone — pollutants especially unhealthy for outdoor workers.
- When climate change-driven heat, drought and record wildfires occurred in the Brazilian Amazon last year, the fires produced massive amounts of wood smoke containing dangerous levels of toxic particulates that cause respiratory disease. Indigenous people living in remote areas had little defense against the smoke.
- Intense heat also impacted Nigeria in 2024, where major dust storms and rising temperatures created conditions that helped increased cases of meningitis — a sometimes deadly disease, especially in poor areas. Escalating climate change is expected to exacerbate pollution and worsen public health in the future.
By razing trees for flood defenses, a Philippine city may have raised its risk
Flood-mitigation infrastructure built in the southern Philippines for more than $100 million by clearing native vegetation could exacerbate flood risk in the future, reports Mongabay’s Keith Anthony Fabro.

How the Sahel junta is responding to climate change amid political isolation
- Torrential rains during the Sahel’s rainy season (July to September) caused widespread flooding, displacing millions and submerging tens of thousands of hectares of cropland across Burkina Faso, Chad, Mali, Niger, Nigeria and Sudan.
- Meanwhile, military coups in Burkina Faso, Mali and Niger have disrupted governance and climate adaptation projects. Political isolation from Western nations has further hindered access to international climate finance, leaving communities struggling to cope with extreme weather events.
- Organizations like the Sahara and Sahel Observatory (OSS) emphasize empowering local communities through initiatives like Water User Associations and agroecology. These efforts focus on sustainable land and water management, leveraging local knowledge for resilience.
- Despite the Sahel’s potential for renewable energy and sustainable agriculture, political instability, weak governance and funding gaps have slowed progress.

Electrochemical removal of ocean CO2 offers potential — and concerns
- Stripping seawater of carbon dioxide via electrochemical processes — thereby prompting oceans to draw down more greenhouse gas from the atmosphere — is a geoengineering approach under consideration for largescale CO2 removal. Several startups and existing companies are planning projects at various scales.
- Once removed from seawater, captured carbon dioxide can be stored geologically or used commercially by industry. Another electrochemical method returns alkaline seawater to the oceans, causing increased carbon dioxide absorption over time.
- In theory, these techniques could aid in carbon emission storage. But experts warn that as some companies rush to commercialize the tech and sell carbon credits, significant knowledge gaps remain, with potential ecological harm needing to be determined.
- Achieving the scale required to make a dent in climate change would require deploying huge numbers of electrochemical plants globally — a costly and environmentally risky scenario deemed unfeasible by some. One problem: the harm posed by scale-up isn’t easy to assess with modeling and small-scale projects.
Balochistan’s Gwadar city sits at the crossroads of climate and conflict
- A new study examines the links between conflict and climate in Pakistan’s Balochistan province, where extreme weather can be a threat multiplier.
- The port city of Gwadar serves as an example, as local residents have long had grievances against the state, which were exacerbated by recent flooding that killed several people and displaced hundreds.
- Experts highlight the absence of data-driven policies, citing a gap in research that has hindered solutions; they call for investment in data and the inclusion of local people in decision-making and infrastructure planning.

Eastern U.S. floods could persist longer toward the end of the century
- Fifty years from now, floods in the eastern half of the United States will last longer as climate change creates warmer and wetter weather patterns, a new study suggests.
- Floods will last longest in the winter, the analysis predicts, marking a shift in damaging flood seasons.
- The trends underscore a need to renovate levees and dams, flood channels, and other infrastructure to protect residents and cities, researchers say.
For a storm-prone Philippine city, flood control is about more than infrastructure
A history of devastating tropical cyclones prompted the construction of flood-mitigation infrastructure in the Philippine city of Cagayan de Oro over the past decade. However, experts say the infrastructure alone won’t be sufficient to address the flood risks amid increasingly frequent and stronger storms due to climate change. Residents also highlight the loss of native […]
Storing CO2 in rock: Carbon mineralization holds climate promise but needs scale-up
- Carbon mineralization is a process by which gaseous carbon dioxide reacts chemically with certain rock types and transforms into solid carbonate minerals. This natural process is an essential part of the long carbon cycle, which has helped regulate Earth’s temperature for millions of years.
- Mimicking this natural process, subsurface mineralization is a human-induced carbon storage technology, with CO₂ injected directly into in-situ basalt, peridotite and other rock types to accelerate mineralization. In 2012, Iceland’s CarbFix project first demonstrated subsurface mineralization and has stored more than 100,000 metric tons of CO₂ since then.
- Proponents say the technology is safe, verifiable and offers rapid permanent CO₂ storage, giving this sequestration method advantages over other options such as reforestation (where forests can be cut or burn) or conventional geologic storage in sedimentary basins (which requires long-term monitoring for leaks).
- Interest in subsurface carbon mineralization is growing: expanding in Iceland, with test projects in the U.S. and Oman, and others recently announced. But investment in field pilots is needed, plus regulatory and policy support, for scale-up. Unlike other geoengineering methods, this technique seems to pose few environmental problems.
Climate funds barely reaching small-scale farmers, report finds
Farmers’ organizations globally are having difficulty accessing climate funds, according to a report published last month. Produced by Netherlands-based think tank Climate Focus on behalf of the Family Farmers for Climate Action, an alliance representing 50 million farmers globally, the report analyzed spending by two of the biggest U.N. funds offering finance for environment and […]
Killer whales have found new homes in the Arctic Ocean, potentially reshaping marine ecology
- The vast ice sheets that historically kept killer whales out of the Arctic Ocean are melting as the region rapidly warms.
- Two small, genetically distinct groups of killer whales now live in the Arctic, after migrating from more southern regions of the Atlantic Ocean.
- Killer whales put pressure on the local ecosystem, including Arctic whales important to Indigenous groups.
Land use change impacting seven planetary boundaries, solutions urgent, say scientists
- A new scientific report lays bare the stark impacts of land-system change and land degradation on planetary health, while also offering solutions to these problems. The report was published on the eve of the 16th session of the UN Convention to Combat Desertification, running Dec. 2-13 in Riyadh, Saudi Arabia.
- Seven of nine planetary boundaries are now adversely impacted by unsustainable land use and other land practices, the report finds. Six of those boundaries are already transgressed, having moved beyond their safe operating space for humanity and into the high-risk zone.
- Scientists warn that the seriously degraded land use boundary, interacting with the other transgressed planetary boundaries, could result in a domino-effect that may rapidly push Earth systems past dangerous and irreversible tipping points, threatening life as we know it.
- Unsustainable agricultural practices are a leading driver of land use degradation globally, responsible for vast amounts of greenhouse gas emissions, the majority of deforestation and freshwater use. Urgent measures are needed to restore ecosystems, shift to sustainable agriculture, and prevent further degradation.
PNG climate migrants sail away with native trees to their new home
Residents of the Carteret Islands in Papua New Guinea are on a “green migration,” contributor Thibault Le Pivain reports for Mongabay. The islanders are leaving their homes due to food shortages resulting from environmental degradation and rising sea levels, and sailing to a larger island in the country, taking with them plants that play important […]
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 […]
With COP29 letdown, climate activists pin their hopes on Brazil
After the recently concluded COP29 climate summit in Azerbaijan failed to raise the amount of funds sought by developing countries for climate initiatives, civil society groups are calling on Brazil, the next host for the conference in 2025, to step up and lead. “Rich countries have failed to honor their responsibilities, and shown up with […]
$125b in ‘climate finance’ funds polluting, rights-violating projects: Report
Multilateral development banks claim to have handed out a record $125 billion in “climate finance” in 2023. However, a recent report finds that some of the funds went to “problematic projects.” “The development banks’ climate finance figures should be read with great caution,” Petra Kjell Wright, campaigns manager at Recourse, a Netherlands-based nonprofit that published […]
Recent surge in methane emissions driven by microbes: Study
Emissions of methane, a greenhouse gas several times more potent than carbon dioxide, increased at record-high rates between 2020 and 2022. A new study suggests that rather than fossil fuels, microbes were responsible for this recent methane surge. Until the early 2000s, fossil fuel production drove much of the increase in atmospheric methane, study lead […]
Shipping emissions reduction sheds light on marine cloud geoengineering
- Unprecedented marine heat waves in the North Atlantic have been driven in part by a recent drop in shipping emissions, leading to a reduction in highly reflective marine clouds that had previously masked some of the warming from humanity’s greenhouse gas emissions, studies find.
- New limits on sulfur dioxide emissions from shipping, introduced by the International Maritime Organization in 2020, created an inadvertent “natural experiment” that is helping to improve models of the interaction between atmospheric aerosols, clouds and climate.
- The sulfur dioxide emissions reduction also provides the clearest test to date of marine cloud brightening (MCB) — a controversial geoengineering approach proposed to mitigate climate change. It shows that to be effective and avoid a dangerous termination shock, MCB would need to be continuous and sustained.
- Reducing atmospheric aerosol pollution has major benefits for human health, but will also inevitably lead to an unmasking of more dangerous climate warming. This means that improvements in air quality must simultaneously be coupled with decarbonization, experts say.
Shorebird populations drop globally, some by a third: Report
Sixteen shorebird species have been reclassified to higher threat categories as the global population of migratory shorebirds across the world saw a substantial decline, according to the latest update to the IUCN Red List of Threatened Species. Conservation partnership BirdLife International, which helps examine the status of the world’s birds for the IUCN Red List, […]
How the oceans fared at the COP16 biodiversity conference in Colombia
- The United Nations Convention on Biological Diversity summit (COP16) took place in Cali, Colombia, from Oct. 21 to Nov. 2.
- Several oceans-related decisions, as well as the formal inclusion of Indigenous peoples and local communities in negotiations going forward, were bright spots at the summit, observers said.
- A key development for the ocean was the agreement, culminating eight years of negotiations, on a protocol for identifying unique areas of the high seas, the two-thirds of the world’s oceans that are international waters, for protection.
- Other important developments included the announcement of new marine protected areas and new funding for ocean conservation.
Forest fires outside tropics drove 60% CO2 surge since 2001: Study
Global carbon dioxide emissions from forest fires have soared by 60% since 2001, driven largely by the burning of forests outside the tropics, according to a new study. There are now, in fact, more emissions from forests located in higher northern latitudes compared to tropical forests, the researchers found. In some areas, such as the […]
Mountain highland bats lack data, face climate threats: Study
Bats in mountainous regions are facing more threats and lack of data compared with their lowland counterparts, a recent study showed. Lead author Rohit Chakravarty in an interview with Mongabay said there is much to be learned about bats dwelling in mountains, which are known to host one-third of the world’s biodiversity and half of […]
Mining drove 1.4m hectares of forest loss in last 2 decades: Report
Global mining activity is increasingly destroying forests, including protected areas, according to a recent analysis. Between 2001 and 2020, nearly 1.4 million hectares (3.5 million acres) of tree cover, an area a third the size of Denmark, was lost from mining-related activity, the analysis from the World Resources Institute (WRI) found. The associated greenhouse gas […]
At least 146 dead in back-to-back tropical cyclones in Philippines
Two tropical cyclones recently struck the Philippines one after the other, leaving at least 146 people dead, according to government reports. The country first felt the peak intensity of Severe Tropical Storm Trami (local name Kristine) on Oct. 24. The storm maintained sustained winds of up to 95 kilometers per hour (59 miles per hour) […]
Population crash means African penguins are now critically endangered
Africa’s only resident penguin species is now officially critically endangered, according to a recent assessment by the International Union for Conservation of Nature (IUCN). Over the past century, the African penguin (Spheniscus demersus) has suffered precipitous declines in its population. In the mid-1950s, there were an estimated 141,000 breeding pairs of African penguins, or 282,000 […]
Karachi expected to receive 2.3 million climate migrants by 2050: Report
A new study finds that Karachi — Pakistan’s most populous city, home to more than 20 million people — could get an influx of 2.3 million climate migrants by 2050. According to a recent report, only Dhaka, Bangladesh, is expected to receive more migrants. If the world fails to meet the Paris Agreement target to […]
Calls for caution as enhanced rock weathering shows carbon capture promise
- Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of geoengineering that could speed up this process and permanently lock away carbon dioxide within decades.
- Startups and research programs are underway across the globe to explore the effectiveness and risks of this climate solution. Spreading rocks such as basalt can sequester carbon and benefit soils, with some studies showing crop yield increases.
- If scaled up, enhanced rock weathering could store gigaton levels of carbon in the future, according to early research. But myriad challenges and uncertainties remain, not least of which is how to accurately calculate and verify how much carbon is being stored, and for how long.
- Some companies are already pushing ahead with deployment, with the idea of profiting from carbon credits, but experts caution that long-term studies are needed to ensure the technique’s efficacy, sustainability and environmental safety.
Women-led groups remain ‘severely underfunded’ for climate action: Report
Women-led Indigenous, Afro-descendant and local community grassroots organizations struggle to access global funding to fight climate change impacts due to structural barriers and stereotypes, a recent report shows. Total government aid, or official development assistance (ODA), for NGOs and women’s rights organizations declined from $891 million between 2019-2020 to $631 million between 2021-2022, according to […]
Six months after its worst floods, Rio Grande do Sul works to bounce back
- A combination of wet El Niño weather and human-induced climate change were key drivers of the worst flooding event in Brazil’s Rio Grande do Sul state earlier this year.
- The flooding affected 90% of the state and displaced more than half a million people.
- Poor land management is also responsible for the region’s vulnerability to floods, as current agricultural practices in the highlands favor runoff and reduce the soil’s ability to soak up water, with lowlands particularly exposed to high waters.
- While some scientists are still deciphering the causes and behavior of the floodwaters, other experts are working to rehabilitate farmland, tackle soil erosion, and source native seeds for ecological restoration.
‘Treat us as partners, central actors’: Interview with Indigenous activist Joan Carling
- Joan Carling recently became the first Indigenous Filipino to win the Right Livelihood Award, often referred to as the Alternative Nobel Prize.
- In an interview with Mongabay, Carling called for the recognition of Indigenous peoples as partners and central actors in conservation and climate action.
- Carling said the push for development projects, the transition to renewable energy, and “fortress conservation” have resulted in criminalization and human rights violations.
- Instead, she said, governments should recognize Indigenous land rights and incorporate traditional knowledge in conservation efforts.
As 25 Earth vital signs worsen, scientists warn of ‘irreversible climate disaster’
- Earth is inching closer to irreversible climate change according to a recent report by an international group of climate researchers and Earth System scientists.
- Tracking 35 planetary vital signs — used to gauge Earth’s response to human activities — researchers found 25 are at record risk levels, including greenhouse gas concentrations, fossil fuel consumption, rising temperatures, forest loss, and biodiversity decline.
- The authors underline the immediate need for wide-ranging climate action to rein in fossil fuel use and control emissions, alongside other measures to stave off a deepening climate crisis. “We are on the brink of an irreversible climate disaster,” they wrote.
Climate change is turning Antarctica green, but not in a good way: study
What’s new: A recent study reveals that the icy Antarctic Peninsula, the northernmost part of mainland Antarctica, has experienced a nearly twelve-fold increase in plant cover over the last 35 years. The greening, driven primarily by the spread of mosses, has accelerated notably since 2016, researchers found. “The landscape is still almost entirely dominated by […]
Drought & climate change force Ethiopia pastoralists to go job hunting
- A severe drought, worsened by climate change, is driving pastoralists in Ethiopia’s Somali region to abandon traditional herding lifestyles in favor of urban labor, leading to significant shifts in their livelihoods.
- Many pastoralists are forced to seek alternative livelihoods in farming, construction and trade, which require new skills and adaptation to urban life.
- Former pastoralists express emotional ties to their traditional way of life and struggle with the demands of new jobs, reflecting the broader impacts of climate change on their identities and futures.
- A land and agriculture expert says nature-based solutions provide an opportunity to help pastoralists adapt to droughts, while government programs are focused on technical support and helping pastoralists achieve alternative livelihoods.
Controversial US marine geoengineering test delayed until next year
- The first-ever field test of ocean alkalinity enhancement in the United States was pushed back to 2025 due to shipping issues. But the geoengineering experiment has also run into public opposition from local environmentalists, commercial fishers and others.
- The test would dump sodium hydroxide (commonly called lye) off the New England coast to study its dispersal as a potential tool for sequestering CO₂.
- Opponents allege this small-scale geoengineering test could harm local wildlife, but researchers say the material will disperse within minutes.
- The scientists say they will also continue to reach out to local communities to alleviate fears over the study.
The Amazon is ablaze again. What it means for us (commentary)
- The Amazon rainforest, devastated by over 70,000 wildfires in 2019, is once again ablaze, threatening even greater destruction of wildlife, human health, and ecosystems.
- Climate change is now a tangible global threat, with rising sea levels and extreme heat affecting entire regions, while indigenous communities, like the Kogi in Colombia, have long warned of these environmental dangers, argues Mark J. Plotkin, an ethnobotanist who co-founded the Amazon Conservation Team.
- The Amazon, which stores one-fifth of the world’s terrestrial carbon, plays a crucial role in regulating global climate, but continued deforestation risks releasing this carbon and disrupting weather patterns far beyond the region.
- This text is a commentary and does not necessarily represent the views of Mongabay.
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.
Inaugural Planetary Health Check finds ocean acidification on the brink
- A first of its kind Planetary Health Check by an international team of scientists indicates that six of nine planetary boundaries are not only transgressed, but are moving further into zones of risk. In addition, recent research shows that a seventh boundary, ocean acidification, is on the verge of transgression.
- Intensifying ocean acidification spells problems for marine life, fisheries and economies. Based on current human CO₂ emission trajectories, this boundary may be breached in a few years, say experts. Others argue this threshold may already have been crossed, with regional acidification above safe limits.
- Together, the nine planetary boundaries identify limits within which Earth systems can operate safely to maintain the planet’s habitability. Transgressing boundaries heightens risks of breaching tipping points that would bring about irreversible shifts to the planet, threatening humanity and life as we know it.
- This inaugural Planetary Health Check is the first of yearly scheduled reports on the wellbeing of Earth systems. Annual reports are now needed due to humanity’s rapid crossing of planetary boundaries, and due to the urgency of providing up to date scientific data to policymakers.
Climate change could threaten newly described ‘shiny’ North American bees
- A recent study examining North American bee species belonging to the Lasioglossum genus has led to the describing of three previously unknown bee species from specimens collected from California, Arizona and Baja California.
- Due to their distinct metallic sheen, one was designated as Lasioglossum (Sphecodogastra) iridescens, while another was named Lasioglossum (Sphecodogastra) dilisena, derived from Sinhala, the majority-spoken language in Sri Lanka, with the word dilisena translating to “shining.”
- The third species is named Lasioglossum (Sphecodogastra) silveirai as a tribute to the late Fernando Silveira of the Federal University of Minas Gerais for his significant contribution to bee taxonomy.
- The newly described species are predominantly found in high-elevation areas in California, where climate change poses a significant threat, so scientists emphasize the importance of further research on their ecology and distribution.
Amazon River and tributaries at record low levels
The Amazon Rainforest’s main rivers are drying out due to an unprecedented drought exacerbated by climate change. Levels have continued to drop since Mongabay’s Sept 9. feature by Fernanda Wenzel. Major rivers such as the Madeira and Negro continue to beat record lows, disrupting life for Indigenous communities and raising concerns about economic and environmental […]
Bangkok turns to urban forests to beat worsening floods
- Bangkok is launching city forests to help beat flooding by soaking up excess rainwater runoff.
- A new park slated to open in December will feature 4,500 trees, a floodplain and a weir to slow the flow of water; another newly opened $20 million city forest acts as a sponge during the monsoon season.
- Bangkok is sinking, and fast: according to the World Bank, 40% of the Thai capital could be flooded by 2030.
- The key to solving the city’s flooding problem is to learn to live with water, not to rid the city of water, says one landscape architect helping to launch the urban forests.
Bats & bees help ni-Vanuatu predict storms — but will climate change interfere?
- In disaster-prone Vanuatu, Indigenous ni-Vanuatu people traditionally rely on plants and animal species as indicators that predict extreme weather events and help them prepare.
- But climate change is affecting weather patterns, and species’ behavior may impact the accuracy of this knowledge and predictions, elders say.
- Government, national organizations and scientists launched a national booklet and a mobile app to both document these traditional knowledge indicators and assess how climate change is impacting their accuracy.
- Researchers use a citizen science approach that encourages youth and community people’s hands-on participation in documenting species and changes.
Study finds Amazon fires nearly 30 times likelier due to climate change
Climate change is turning the humid rainforest of the western Amazon into an ecosystem nearly 30 times more prone to fire, according to the 2023-2024 State of Wildfires report. The study shows that between March 2023 and February 2024, rising temperatures, reduced rainfall, drier air and less resilient forests set up the region for a […]
Record drought in Yucatán prompts revival of ancient Maya rain ceremony
- Maya farmers in Yucatán, Mexico, have rekindled a pre-Hispanic ceremony that calls for rain from the god Cháak as the state suffers its worst drought in 50 years.
- The extended dry season has prevented local farmers from generating sufficient harvests to provide enough food to sustain Indigenous people from remote regions.
- In early May, the Yucatán Peninsula experienced a record high temperature of 43.7°C (110.7°F) after an already year-long drought.
- Pollution from industrial pig farms and monocrop plantations is contaminating groundwater systems and cenotes, considered sacred by the Maya and relied upon to supply farms in rural communities.
Will we be ready? Geoengineering policy lags far behind pace of climate change
- The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.
- Now, as climate change impacts intensify, the debate over what safe, effective national and international geoengineering policies should look like has intensified among academics, regulatory and advisory bodies and researchers.
- Meanwhile, scientists continue trying to find out if geoengineering (the deliberate altering of global atmospheric or oceanic conditions), can help cool off a dangerously warming planet without triggering harmful effects.
- Some warn geoengineering is too risky and want field research stopped. Others say research is urgently needed so decision-makers can understand geoengineering options and risks, so as to make informed choices. For now, few definitive road signs exist to guide policymaking.
Severe droughts isolate Amazon communities, study finds
The rivers of the Amazon Basin serve as highways for much of the region. Boats are often the easiest and quickest way to get goods and services in and out of remote communities and large cities alike. However, the Amazon Basin has experienced several severe droughts over the last 20 years, which have caused river […]
Fires devastate critical refuge for hyacinth macaws
Recent fires in Brazil’s Pantanal wetlands have burned through nearly 80% of a refuge that serves as critical habitat for the iconic hyacinth macaw, according to media reports. The striking, cobalt-blue hyacinth macaw (Anodorhynchus hyacinthinus) is the largest parrot species in the world, reaching up to 1 meter (3.3 feet) in length from tail tip […]
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.
Climate change threatens public health, raising the spread of food-borne diseases
- A new study finds that climate change is affecting the distribution and spread of food-borne diseases.
- An increase in the number and severity of heatwaves, droughts, and heavy precipitation events are all expected to lead to a rise in food-borne diseases, hitting Africa and Asia particularly hard.
- Investing in research and innovation can provide valuable insights into the underlying mechanisms of climate change-pathogen interactions and novel solutions for mitigating effects.
- For example, the Cameroon National Climate Observatory, ONACC, already provides national sectors, such as agriculture, livestock, and health with forecast climate information translated into local languages to facilitate monitoring in the context of global warming.
As waterbodies lose oxygen, are we breaching a potential planetary boundary?
- A new perspective piece argues that aquatic deoxygenation — the depletion of oxygen in marine and freshwater environments — should be considered its own “boundary” in the planetary boundary framework first proposed by scientists in 2009. Human-caused nitrogen pollution and climate change have greatly worsened aquatic deoxygenation worldwide.
- The planetary boundary framework defines nine natural biophysical and biochemical system processes that maintain the resilience of the Earth system, allowing life to thrive. But each boundary includes limits within which humanity needs to safely operate.
- The paper’s lead author says that increased scientific understanding of dissolved oxygen in marine and freshwater environments shows that it regulates, and is regulated by many of the other planetary processes, which in turn warrants the inclusion of aquatic deoxygenation in the planetary boundary framework.
- The framework is a rapidly evolving theory. Whether aquatic deoxygenation is already indirectly taken into account by the existing framework, as some argue, or whether it should be considered as its own planetary boundary remains to be determined.
Cloud brightening over oceans may stave off climate change, but with risk
- Marine cloud brightening (MCB), the spraying of sea salt aerosols or other fine particles into clouds to artificially brighten them and increase the sun’s reflectivity, is a proposed strategy to ward off the full effects of climate change.
- However, this solar radiation management (SRM) geoengineering technique is highly controversial, and experts say governance of MCB field experiments and deployment is needed now at the national and international levels.
- Ongoing efforts to include marine cloud brightening under an international anti-marine pollution treaty, the London Protocol, could be one effective route to setting standards for research and field experiments.
- But if MCB is deployed on a large scale, some experts say there is the potential for serious negative effects on the global climate system. These impacts could be especially severe if deployment is uncontrolled and lacks science-based governance.
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 […]
Uttarakhand villagers thirst for water as tourism, temps & development rise
- An influx of tourists and new residents to Uttarakhand, driven by heat waves and work-from-home options, is straining local resources, particularly water.
- Nearly 12,000 natural springs reportedly have dried up in recent years, with 90% of Uttarakhand’s population depending on these vital water sources.
- Widespread construction for tourism disrupts aquifers and natural water percolation, exacerbating water scarcity and affecting water quality; water sources are further threatened by changing rainfall patterns and rising temperatures.
- Local residents, especially women and marginalized communities, face increased hardships in accessing water amid growing allegations of water diversion by hotels.
Climate change could return a stolen lake to Indigenous people, a century later
- Semá:th Xhotsa, or Sumas Lake, in Canada was the center of First Nations’ food system and culture, before European colonists drained it in 1924 to create farmland.
- Almost 100 years later, catastrophic flooding threatens to refill the lake and displace the farmers.
- First Nations people and university researchers have proposed restoring the lake ecosystem to adapt to climate change-driven flooding, and as a method of reparation, but the local government is pushing back.
China is latest country to oppose EU regulation to track deforestation
In a recent development, China has opposed the European Union’s landmark regulation to prevent deforestation-linked commodities from entering the EU market. This update comes from GD Holz, the German timber trade association. The EU Deforestation Regulation (EUDR) is designed to ensure that forest-related products that are sold in the EU market are deforestation-free. That is, […]
As climate change shakes up global map of venomous snakes, health risks abound
- Researchers assessed the impacts of climate change on 209 species of venomous snakes from now until 2070, and concluded that while some may disappear from their range, others are likely to expand to new areas.
- Venomous snakes are among the most dangerous animals on the planet, responsible for at least 80,000 deaths a year, mostly in low-income countries with limited access to antivenom.
- Another impact on public health is the reduction in drug development: snake venom has great pharmacological potential, contributing to the production of medicines used to treat illnesses ranging from cancer to heart failure.
- Ecosystems will also face an imbalance as new species move in and existing ones go extinct, since snakes play a critical role in controlling the population of other animals such as rodents, which are also disease vectors.
Geoengineering gains momentum, but governance is lacking, critics say
- As the climate crisis advances, geoengineering — intentionally modifying Earth systems on a large scale to cool the planet or store additional carbon — is increasingly a hot topic. But an intense debate is raging as to how to govern research and deployment of these deeply contentious strategies.
- Stratospheric aerosol injection (SAI) — involving the release of sunlight-blocking particles such as sulfur dioxide into the lower atmosphere to block the sun’s rays — is at the forefront of a range of geoengineering technologies and approaches.
- Most SAI research to date involves modeling, while small-scale experimentation is foundering. SAI, though likely capable of cooling Earth’s climate, comes laden with governance challenges, myriad uncertainties and knock-on effects to the climate, ecosystems and human health.
- Projected deployment within a decade or two is cause for concern, say experts who warn that policy guidance and regulatory mechanisms at the national and international levels are now patchy at best, leaving huge gaps in oversight, transparency and monitoring of field research and potential deployment.
Cerrado’s current drought impossible without human-caused climate change: Study
- Since early 2000s, Brazil’s Cerrado has been suffering severe drought episodes, with water shortages affecting hydroelectric power, agriculture and water access. Its water supply has also been under pressure from encroaching agriculture and deforestation.
- Analysis of 700 years of climate data indicated an unprecedented drying trend that started around the 1970s, which experts say was made possible by human-induced warming, and not by climate’s natural variability.
- Researchers collected data from stalagmites in one cave in the state of Minas Gerais and built a climate record for the Cerrado.
Scientists are racing to save South Asia’s butterflies from the threat of extinction
- Butterflies are some of Bangladesh’s most prolific pollinators and important ecosystem indicators.
- Insects, including butterflies, are especially vulnerable to climate change and other human-caused ecosystem changes.
- Despite the increasing threat of extinction, few legal protections or conservation initiatives focus on preserving butterflies and other insects.
- South Asian scientists are engaging communities in citizen science to garner attention to often-overlooked butterfly species.
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.
Are the Amazon’s biggest trees dying? Forest coroners investigate
- As tropical forests are degraded and decline at increasing rates the world over, the fate of these forests’ largest trees remains unknown.
- Big trees store a huge amount of carbon, so assessing their current mortality rates and causes of death (especially due to escalating climate change) is vital to calculating how much tropical forest carbon sinks could decline in the future.
- The Gigante project, getting started in the Brazilian Amazon in June 2024, is initiating an innovative new protocol utilizing detailed drone surveys combined with ground truthing to evaluate tropical big tree mortality.
- The project has begun an identical survey in Panama and will conduct others in Malaysia, Cameroon and at another Amazon location. Knowledge of how tropical big trees are faring could help improve climate model accuracy. A Mongabay reporting team joined the Gigante project in Brazil at the start of this groundbreaking work.
In sub-Saharan Africa, ‘forgotten’ foods could boost climate resilience, nutrition
- A 2023 study was recently awarded the Cozzarelli Prize from the Proceedings of the National Academy of Sciences for its work identifying “forgotten” food crops in sub-Saharan Africa that may be more resilient to climate change than the region’s current staple crops of maize, rice, cassava and yams.
- The study found that West Africa and Central Africa would experience the largest decrease in suitability for current staple crops by 2070, and that maize was the most vulnerable of the staples.
- In addition to identifying 52 food crops that will likely be better-suited to the region’s future climate — and which have more nutritional value than staple crops — these researchers have already succeeded in introducing some of the overlooked crops to local communities.
Don’t even study it: Geoengineering research hits societal roadblocks
- As climate change accelerates, some scientists are calling for more field research into solar geoengineering concepts. However, these ideas are running into opposition from other researchers, some governments and the public.
- A series of recent setbacks has put solar geoengineering research on the back foot, attempting to figure out a way to navigate the opposition.
- Proponents of field research say it would help humanity better understand the potential and problems with solar geoengineering, while opponents argue that there are too many risks and it could take our eye off the ball: cutting carbon emissions.
- The debate has spilled into the international arena, pitting nations that support greater research against those that would like to see a solar geoengineering non-use agreement.
Sun block: The promise and peril of solar geoengineering
- Recent research and interest, especially from the U.S. government, has pushed a solar geoengineering idea known as SAI, or stratospheric aerosol injection, to the top of lists of potential ideas to cool the planet. SAI would use fleets of high-flying aircraft to disperse sunlight-reflecting particles, including sulfates, into the stratosphere.
- As climate change worsens and carbon emissions continue to rise, researchers say we must be ready with other potential tools to stave off total catastrophe, such as the disintegration of the West Antarctic Ice Sheet with sea-level rise that would drown coastal cities.
- But critics say any geoengineering is too unpredictable and could allow governments to lower their ambitions on cutting emissions. They also argue that there’s no global governance policy to implement geoengineering justly.
- As debate intensifies, however, some feel it’s only a matter of time, given the current and projected trajectory of warming, until the world seriously considers geoengineering deployment.
Africa’s great ape sanctuaries are feeling the heat from climate change
- While a growing body of research highlights the impacts of climate change on wild apes, sanctuaries caring for apes are also feeling the impacts of a warming world.
- Sanctuaries across Africa are affected by changing weather patterns, including both droughts and floods, increasing the challenges of caring for resident apes.
- Extreme weather also increases the likelihood of human-wildlife conflict in conservation areas, and makes daily life more difficult for sanctuary staff and their families and communities.
Climate surprises: Amazonia and the lessons of Brazil’s catastrophic flood in Rio Grande do Sul (commentary)
- Brazil’s catastrophic flood in the state of Rio Grande do Sul is helping to raise public awareness of climate change but has had no visible effect on the Brazilian government’s actions and plans on greenhouse gas emissions. The flood provides an example of “climate surprises,” which are expected to increase further in frequency and severity with projected global warming.
- Amazonia has already been the victim of a series of such surprises, and these threaten the Amazon forest with collapse and the consequent pushing of global warming beyond a point of no return.
- Except for the Ministry of the Environment and Climate Change, the rest of Brazil’s presidential administration is on the wrong side of the issue, expanding fossil fuel extraction and promoting deforestation in various ways. An immediate turnaround is needed.

As the world burns, can we learn to live with wildfire health risks?
- Climate change is driving or contributing to increased risk of extreme wildfires in many parts of the world, and experts say urgent action on climate change is needed.
- Finding ways to better manage land use can help reduce the likelihood and severity of wildfires: In landscapes where fire is natural, experts say we should bring back historic fire regimes through cultural burning and prescribed burns.
- Experts say more needs to be done to protect vulnerable populations from wildfire smoke, such as those with preexisting medical conditions, pregnant women, children and seniors, who may be impacted even thousands of miles from a fire’s source.
- Smoke prediction apps, early-warning systems and air filtration systems can help people reduce smoke exposure.
The health impacts of escalating megafires are everyone’s problem
- Increases in extreme wildfires in many parts of the world are fueling concerns over the impacts of smoke on human health, with global warming, forest management and land-use change the primary drivers of increasing wildfires.
- Similar to other types of air pollution, wildfire smoke is associated with a wide range of short-term health impacts, especially for vulnerable groups such as the elderly and people with preexisting medical conditions.
- Wildfire smoke is increasingly adding to the cumulative air pollution burden experienced by modern industrial societies — even in remote or rural areas.
- Emerging evidence also suggests wildfire smoke may have long-term health impacts and contribute to increased risk of chronic conditions.
Pantanal’s intense blazes stoke fears of another destructive fire season
- The fire season has started early in the Brazilian Pantanal, amid concerns the biome might see another catastrophic fire season like in 2020.
- The first 23 days of June alone saw more than 2,100 hotspots recorded, the highest figure by far for the month, and more than 627,000 hectares (1.5 million acres) burnt.
- The Pantanal is going through a severe drought, which, coupled with climate- and human-driven disruption of its usual ebb and flow of water, has left the biome drier and more vulnerable to fires, experts say.
- Although authorities are better prepared to fight the fires than in the past, civil society organizations say they worry the response is insufficient in the face of a new, more extreme reality.
Activists blame policy failures over climate change for Nepal Terai’s water crisis
- Deforestation and unregulated extraction of resources in the youngest and most fragile of the Himalayan ranges have disrupted groundwater recharge and increased soil erosion, contributing to the current water crisis.
- Activists criticize the government for blaming global climate change to deflect from local accountability and for neglecting Chure’s conservation while focusing on Himalayan snowmelt.
- Despite conservation efforts, government plans to export construction materials from Chure continue, risking further environmental damage and criminal influence.
Living under the apartheid of Brazil’s soybean capital
- Brazil produces more soybeans than any other nation, and the city of Sorriso, Mato Grosso, leads this production, which drove the municipal per capita GDP from 27,000 reais to 132,000 reais ($15,800 to more than $25,000) in the last 10 years.
- The highway running through town helps illustrate the contrast between gated communities of luxury homes along one side and precarious homes where agricultural workers and family farmers live amid vulnerable social situations on the other.
- Family farmers struggle to keep producing amid land disputes and clouds of pesticides that destroy their crops, ruin honey production and raise cancer rates — which are twice as high in Sorriso than the state average.
- Lives are also lost to organized crime in Sorriso, the municipality with the sixth-highest murder rate in the nation, and also to agribusiness itself, with dozens dead after becoming engulfed in soybean silos.
Women in Sierra Leone unite after devastating floods
FREETOWN, Sierra Leone – In this episode of Mongabay Sessions, Romi Castagnino, Mongabay’s associate video producer, interviews documentary director Ibrahim S. Miles Kamara about his impactful film, Freetown Floodfighters: Women’s Resilience on the Frontline. This documentary highlights the efforts of community groups led by women to build resilience against climate change-induced floods in Freetown, Sierra […]
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.
‘Non-market’ solutions to deforestation need more support, advocates say
- In a report released May 29, three environmental groups called for a shift away from carbon markets and toward “non-market” solutions to deforestation.
- The Paris Agreement has a clause calling for such solutions, which the groups said could include financing for Indigenous groups, payment for ecosystem services, and debt relief.
- The report criticized carbon markets, saying incentives for brokers and project developers are misaligned with global environmental priorities.
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.
Are carbon credits another resource-for-cash grab? Interview with Alondra Cerdes Morales & Samuel Nguiffo
- Indigenous and traditional communities around the world are increasingly being recognized for their stewardship of forests.
- That’s led to their lands being seen as prime targets for carbon credit projects, the idea being that the carbon sequestered here can be sold to offset emissions elsewhere.
- While some Indigenous communities have welcomed these projects and the funds they bring in, others say they’re just another example of the monetization of natural resources that’s driving the climate crisis in the first place.
- Mongabay interviewed two leading Indigenous voices on both sides of the debate, who say the issue is a deeply nuanced one that carries implications for Indigenous land rights, culture and sustainability.
Report ranks 60+ ideas, including geoengineering, to save the Arctic
- Given that the serious impacts of climate change are rapidly escalating, some scientists, backed up increasingly by governments, are looking into extreme measures such as geoengineering to slow the rate of change.
- A new report examines 61 climate mitigation ideas for the Arctic, including geoengineering.
- The report ranked tried and true measures, like restoring peatlands, the highest, but some geoengineering ideas, such as solar geoengineering, also ranked high.
- Researchers say, however, that while geoengineering ideas may be worth studying, the goal right now must be to aggressively cut emissions. Some also fear that geoengineering will become a costly distraction, diverting attention from the need for fossil fuel companies to cut production, and for decarbonization of the economy.
Amid ravaging wildfires in Venezuela, experts cite institutional collapse
- Since the start of the year, Venezuela has been experiencing record-breaking fires. Apart from the highest number of fires in any January and February for the last two decades, wildfires continued all the way to early May, devastating national parks and affecting the capital of Caracas.
- Some experts say that in 2024 so far, up to 2 million hectares (4.94 million acres) of land appear to have already burned.
- Higher temperatures, drought and the fact that Venezuela lacks fire-tolerating plants have been contributing to more intense fires, which have been made worse by the country’s institutional failures.
- Experts say that a lack of adequate institutions, a collapse of public services and an absence of planning and monitoring strategies have resulted in Venezuela being unable to handle the wildfires.
Bangladeshi farmers find zucchini’s high yields & low costs palatable
- Though long considered “foreign” to Bangladeshi farmers, zucchini squash is now cultivated among growers who value its high productivity, lower production cost and short growing time.
- Farmers living in dry regions and river islands prefer to cultivate this vegetable, where watering the plant is an issue.
- Bangladesh Agricultural Extensions expects more zucchini squash cultivation in the coming days based on farmers’ enthusiasm and growing local demand in the market.
From polling stations to weather stations, the heat is on in India (commentary)
- Parts of India are facing a heatwave, for which the heat in the state of Kerala is a curtain raiser. Kerala experienced its first recorded heatwave amid the ongoing election campaign.
- Heatwaves, droughts and floods do not distinguish along political lines. If the destruction is across board, the mitigating action also has to be across political lines, writes Mongabay-India’s Managing Editor, S. Gopikrishna Warrier, in this commentary.
- Climate change poses economic, social and political challenges, influencing election discourse and policy agendas.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Rocky rollout for Bangladesh’s ambitious solar-powered irrigation plans
- Nearly half of irrigation costs in Bangladesh are due to irrigation, and the diesel pumps that currently power irrigation networks are responsible for 1.6% of the country’s greenhouse gas emissions.
- To address both issues, the government is rolling out a nationwide program to gradually replace these diesel pumps with solar-powered ones, aiming to slash irrigation-related emissions by 0.8 million metric tons by 2030.
- It also says that given that irrigation use is concentrated in the non-monsoon months, the surplus energy generated by the pumps the rest of the time can be fed into the grid, providing up to 480 gigawatt-hours of clean energy a year.
- In pilot programs, however, farmers have expressed concern over the reliability of the solar pump systems, especially for water-intensive crops such as rice and corn, and have also noted that their irrigation costs remain the same.
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.
Uttarakhand limits agricultural land sales amid protests & tourism development
- Following widespread protests, Uttarakhand’s Chief Minister Pushkar Singh Dhami has issued orders to district magistrates to deny permission to sell agricultural lands to those outside the state.
- With just 14% of its land designated for agriculture and more than 65% of the population relying on agriculture, calls for legislation to safeguard residents’ land rights have intensified.
- With a lack of comprehensive, updated land records, monitoring the usage of farmlands for nonagricultural purposes has become challenging.
- Lack of employment opportunities and resources as well as shifting weather patterns and climate change have pushed numerous farmers to sell their land holdings.
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.
In largest ever study, Indigenous and local communities report the impacts of climate change
- Indigenous peoples and local communities are reporting a series of tangible and nuanced impacts of climate change, according to a new study.
- The study collected 1,661 firsthand reports of change in sites across all inhabited continents and aggregated the reports into 369 indicators of climate change impacts, including changes in precipitation, plant cultivation and marine ecosystems.
- Existing measures to track climate change impacts are barely able to relate to the diverse and complex ways in which local people experience and observe environmental changes, according to the authors. For instance, instrumental measurements might capture changes in rainfall patterns but miss crucial relationships between climate change awareness, sensitivity and vulnerability.
- This research constitutes the largest global effort by Indigenous peoples and local communities to compile and categorize local observations of climate change and its impacts.
Faced with an extreme future, one Colombian island struggles to rebuild
- In 2020, Hurricane Iota destroyed most of the housing and infrastructure on the Island of Providencia, in Colombia’s Caribbean archipelago of San Andres.
- Although the government sent aid and rebuilt homes, communities complained they were left out of the consultation process and that the reconstruction had been poorly done, without addressing the island’s increased vulnerability to climate change.
- Locals sued the government, obtaining a reopening of consultations, which the new left-wing government has agreed must reach a solution that accords with the islanders’ traditional customs.
- More than 700 islands in the Caribbean could be increasingly exposed to more extreme weather, as climate change threatens to make events such as hurricanes more destructive.
Rainwater reserves a tenuous lifeline for Sumatran community amid punishing dry season
- Kuala Selat village lies on the coast of Indragiri Hilir district on the Indonesian island of Sumatra.
- In the first half of the year, residents of the village arrange buckets and drums to collect rainwater to meet their daily needs.
- They will then stockpile water to last through the dry months from June-September, but a longer dry spell has led to an acute shortage of water.
- Residents say they believe the water crisis in the village was linked to bouts of diarrhea, and that many fled the village during an outbreak.
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.
We need rapid response support for Indigenous peoples in the face of growing extreme weather events (commentary)
- Climate change can sometimes feel distant and intangible, but the increasingly frequent extreme weather events in tropical forest regions like the Amazon and Congo Basin are already having very real-world impacts on Indigenous and other local communities in these areas.
- While Indigenous and grassroots organizations are often the first responders and are best placed to know the needs of their communities, they face huge challenges in accessing heavily bureaucratic disaster response funding.
- This is why we are calling for the establishment of a dedicated fit-for-purpose rapid response fund for them to be able to respond and recover from such events.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
‘Another catastrophe’: Flooding destroys Indigenous agroforestry projects in Peru’s Amazon
- Heavy rains likely caused by El Niño began flooding Peru’s Ene River at the beginning of March, with waters reaching around 2 feet high and spreading across 5,000 hectares (12,355 acres) of land occupied by around 300 Indigenous Asháninka families.
- Families in five Asháninka communities lost their homes as well as years of work on successful and sustainable agroforestry projects for cacao, coffee and timber, among other products.
- The flood waters have only recently receded, so a long-term or even mid-term plan for recovering their agroforestry projects hasn’t been developed yet.
- The Asháninka have faced many other setbacks over the years, from drug trafficking groups to unsustainable development projects, but have often overcome them to defend their territory. This flood marks the latest setback.
UN probes controversial forest carbon agreement in Malaysian Borneo
- The government of Sabah state in Malaysian Borneo will continue to move forward with an opaque nature conservation agreement despite concerns raised by the United Nations.
- In a letter, the U.N. calls in question the transparency of the agreement and the state’s approach to the human rights law principle of free, prior and informed consent.
- The agreement was signed by state officials and a representative of a Singaporean company in 2021. Shortly after news of the deal became public, some Indigenous groups in the state said they hadn’t been consulted or informed about the deal covering 2 million hectares (4.9 million acres) of the state’s forests.
- The U.N. letter was written by a group of “special procedures experts” with mandates established by the U.N. Human Rights Council, including the special rapporteurs on the rights of Indigenous peoples, on human rights and the environment, and on the right to development.
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.
Brazilian youngsters discuss how they are tackling the climate emergency
- Affected by drought, pollution, high waters and floods, young people from different Brazilian states describe how climate change is impacting their routines and causing illness, malnutrition, displacement and school disruption.
- According to a UNICEF report, 2 billion children and adolescents in the world are exposed to risks arising from the climate emergency; in Brazil, there are 40 million affected children and adolescents — 60% of Brazilians under 18.
- According to experts, the climate crisis is a crisis of the rights of children and adolescents, as it affects everything from the right to decent housing and health care to education and food, leading to problems in child development and learning abilities.
Climate change brews trouble for tea industry, but circular solutions await
- In its many varieties, tea is renowned as one of the world’s most consumed beverages, second only to water.
- Like many other agricultural crops, tea production impacts the environment: Production in tropical countries is implicated in deforestation, pollution and impacts on fragile biodiversity.
- Climate change imperils the tea industry, threatening to reduce yields and hammer millions of smallholder farmers who derive their livelihood from the crop.
- Experts say circular solutions can help build resilience in tea production against climate change, while at the same time lessening its environmental impact.
Big problems for little animals when floodwaters rise, study finds
- Increasingly frequent and severe weather events are testing the resilience of both human and animal communities across Africa; Cyclone Idai, which made landfall in Mozambique in 2019, caused massive flooding that killed more than 1,600 people.
- Researchers studying the aftermath of Idai in Gorongosa National Park found many smaller-bodied animals in low-lying areas drowned or starved before forage recovered from the severe flooding that followed the cyclone.
- Larger animals were able to both reach higher ground ahead of rising waters and adapt to reduced availability of food in the long months it took for the floodplain to dry out and recover.
- The study is a rare example of close monitoring of animals before, during and after an extreme weather event, and provides conservationists with important insights into planning and managing protected areas in a changing climate.
Why language is central to the survival of cultures and communities
- More than half the world’s languages could go extinct by 2100, The United Nations Permanent Forum on Indigenous Issues says.
- Roughly 4,000 of the world’s 6,700 languages are spoken by Indigenous communities and contain knowledge key for conservation and human health, but multiple factors threaten their existence along with their speakers’ cultures.
- Joining the podcast is Jay Griffiths, author of ‘Wild’ and other seminal books about how language and relationship are central to cultural survival, and why connection to the land is a universal human right.
- The guest also draws parallels between humans, nature and culture: “There’s great research that suggests that we learned ethics from wolves [of taking] an attitude to the world of both me the individual, and of me the pack member,” she says.
Studies still uncovering true extent of 2019-20 Australia wildfire catastrophe
- Australia’s 2019-20 bushfires burned with unprecedented intensity through a total of 24 million hectares (59 million acres), an area the size of the U.K.
- New research shows total costs incurred to the tourism industry from that single bushfire season may be 61% higher than previously calculated.
- Up to 1.5 billion wild animals may have perished in the fires, and new research is uncovering the cost to individual species as a result of the fires.
- One study published shows 15% of all known roost locations of the gray-headed flying fox, Australia’s largest bat species, may have been directly impacted by the fires.
Study on Brazilian heat wave deaths shows gender & racial disparities
- A new study estimates that the deaths of nearly 50,000 people in Brazil in recent decades could be attributed to the occurrence of heat waves, and it points out that these extreme events have become increasingly frequent.
- The paper reveals that Blacks, Browns, females, older adults and those with lower educational levels are the most affected population subgroups, suggesting that the impacts of heat waves are felt unevenly, thus exposing socioeconomic inequalities.
- The researchers analyzed data from 14 metropolitan regions with a population of 74 million people, representing nearly one-third of Brazil’s population.
- This research is important because it joins others in analyzing racial and gender dimensions of the populations most vulnerable to extreme events, the scientific coordinator at Iyaleta Research Association says.
Sumatra firefighters on alert as burning heralds start of Riau dry season
- On the northeast coast of Indonesia’s Sumatra Island, the first of two annual dry seasons led to a spike in wildfires in some peatland areas in February.
- In the week ending March 2, Indonesian peatland NGO Pantau Gambut said 34 hotspots, possibly fires, were identified by satellite on peatlands in Riau province.
- Emergency services in the province have been concentrated to the east of the port city of Dumai, where a fire started in the concession of a palm oil company, according to local authorities.
In climate-related flooding, a Ugandan river turns poisonous
- Uganda’s Nyamwamba river, in the Rwenzori Mountains, has begun to flood catastrophically in recent years, partly due to climate change.
- Along the river are copper tailings pools from an old Canadian mining operation, which are becoming increasingly eroded by the flooding.
- According to a series of studies, these tailings have been washing into the water supply and soil of the Nyamwamba River Basin, contaminating human tissue, food and water with deadly heavy metals.
- Cancer rates are higher than normal near the tailings pools, and scientists fear that as the flooding continues to worsen, so will the health crisis.
As lightning strike fatalities increase, Bangladesh still has no reliable preventive measures
- Between 2011 and 2020, lightning strikes claimed the lives of 2,164 people, or nearly four people every week, in Bangladesh, according to the country’s disaster management department. However, a Bangladeshi NGO reports at least a thousand more lightning related fatalities between 2010 and 2021.
- Researchers linked the increased frequency of lightning with climate change; as for the increased death toll, they blamed the government’s inefficient protection measures, including the lack of tall trees.
- To reduce the number of fatalities, the government has started working on long-term solutions, such as installing lightning arresters and growing palm trees. Nevertheless, a significant sum of money is being squandered and nothing functions as expected, say experts.
Climate change brings a river’s wrath down on western Uganda
- Since the 1960s, Uganda’s climate has warmed by an average of 1.3°C (2.3°F).
- The warming is partly responsible for an increasing number of catastrophic floods on the Nyamwamba River, in western Uganda’s Rwenzori Mountains.
- In 2020 alone, 173,000 people were affected by flooding in Kasese district, when 25,000 houses were destroyed.
- Many of those rendered homeless by the floods continue to languish in temporary housing camps four years on.
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.
Harsh dry season sours harvest prospects for Java coffee farmers
- Indonesia is the world’s fourth-largest producer of coffee, after Brazil, Vietnam and Colombia, but the archipelago’s farmers are less productive than their competitors.
- In East Java province, farmers have seen yields plummet as a protracted water deficit shrinks fruit and introduces pests.
- Total output is expected to drop by more than 20% this season, while increasingly frequent extreme weather may pose challenges to the viability of some smallholders in lowland areas of Indonesia.
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.
As climate disasters claim their children, Bangladeshi mothers seek safety in bigger families
- Climate change is exacerbating child mortality in flood-prone areas of Bangladesh, prompting mothers to have larger families as a response to the fear of losing children to disasters.
- Studies indicate an 8% surge in infant mortality risk in flood-prone regions, resulting in more than 150,000 lives lost between 1988 and 2017.
- While Bangladesh has seen improvements in disaster management, reduced cyclone deaths, and progress in health for mothers and children, climate change poses new threats, especially to vulnerable coastal communities lacking adequate protection.
- A National Adaptation Plan offers solutions such as water conservation and livelihood opportunities, but challenges like funding, coordination and transparency need attention for effective implementation, experts say.
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.
In Bangladesh, sunflower grows where other crops don’t amid increasing salinity
- The changing climate, rising sea levels and other anthropogenic factors are forcing a vast area of Bangladesh’s coastal zone to remain barren due to the presence of salinity in arable land.
- Overcoming these hurdles, coastal farmers, with the support of the government and various nongovernmental organizations, are now farming sunflowers and benefiting from the alternative crop.
- Bangladesh currently produces only 10% of the oilseeds it uses; imports from different countries meet the rest of the demand.
- The government estimates that the country could produce sunflower to meet the local demand for cooking oil by up to 26% by cultivating the oilseed in saline-prone zones.
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.
Maluku farmers sweat El Niño drought as Indonesia rice prices surge
- Rice prices surged across Indonesia during the second half of 2023 as the effects of El Niño led to widespread crop failures.
- In December, President Joko Widodo ordered military personnel to help farmers plant rice in a bid to boost domestic production, and curb food price inflation.
- On Buru Island, Mongabay Indonesia spoke with farmers who described risks of conflict as water scarcity forced farmers to queue for access to water.
Java’s crumbling coastline and rising tide swamp jasmine flower trade
- Growers of jasmine flowers in lowland areas of Indonesia’s Central Java province are vulnerable to coastal erosion and rising sea levels.
- Research published in 2022 showed Central Java’s Semarang was among the fastest-sinking major cities in the world.
- Jasmine grower Sobirin has altered his home on three occasions since 2010, raising the floor to adapt to increasing tidal surges.
In Mexico, Xalapa’s chronic water scarcity reflects a deepening national crisis
- Residents of Xalapa, the capital of Veracruz, Mexico, have been struggling with a worsening water shortage that often leaves people without daily access to household water for washing.
- The problem is nationwide, in 30 of 32 states, forcing residents to purchase and recycle water and postpone bathing.
- Experts have blamed climate change and extreme heat for the country’s water shortages; others also blame corruption that allows companies to pay for unlimited water use.
- Deforestation for development, an increase in construction and building and population increases are also factors.
Bangladeshi farmers eye moringa as a climate and economic solution
- Farmers in Bangladesh are increasingly turning to the fast-growing, drought-resistant moringa (Moringa oleifera) tree, which is indigenous to South Asian nations such as India, Pakistan, Bangladesh and Afghanistan.
- Researchers say moringa is beneficial for human health, as both the leaves and the fruits are rich in nutrients and minerals.
- Researchers also suggest that moringa cultivation could be a part of smart agriculture as climatic patterns change, as the plant can tolerate extreme heat and cold.
- A Bangladeshi entrepreneur has been working to create a social movement and entrepreneurship in moringa cultivation and marketing since 2017; so far, he has engaged some 5,000 farmers in 20 districts of Bangladesh.
Indigenous effort in Bangladesh helps reverse endangered fish’s slide to extinction
- Unchecked logging and quarrying of rocks from streambeds in Bangladesh’s Chittagong Hill Tracts led to springs drying up and populations of putitor mahseer fish, an endangered species, disappearing.
- The situation was worsened by climate change impacts, characterized here by a more intense dry season during which even streams that once ran year-round now dry up.
- A project launched in 2016 and backed by USAID and the UNDP is working with Indigenous communities to reverse this decline, starting with efforts to cut down on logging and quarrying.
- As a result of these efforts, areas where forests have been conserved have seen the flow of springs stabilize and populations of putitor mahseer and other fish revive.
Markets and forests: 7 takeaways from our series on the forest carbon trade
This is the wrap-up article for our five-part series on forest carbon credits and the voluntary market. Read Part One, Part Two, Part Three, Part Four and Part Five. Mongabay recently published a five-part series on the carbon trade and its use as a tool to address climate change. The exchange of carbon credits, typically […]
The future of forest carbon credits and voluntary markets
- Observers predicted that 2023 would be a “make-or-break” year for voluntary carbon markets and “an inflection point” for their role in addressing climate change and global deforestation.
- Amid criticisms around carbon accounting, carbon neutrality claims, and issues with forest communities, governance bodies say they’ve worked to increase consistency and “integrity” for the voluntary carbon market and specifically the forest conservation strategy known as REDD+.
- Concerns remain from a variety of observers, including those who say the focus of credit-buying companies should be on eliminating their carbon emissions from across their entire suite of operations.
- But proponents of markets say that while decarbonizing is absolutely necessary to minimize the rise in global temperatures, the carbon trade allows for the mitigation of pesky residual emissions that it’s either impossible or too expensive to get rid of at this point.
2023’s top ocean news stories (commentary)
- Marine scientists from six international research and conservation institutions share their list of the top ocean news stories from 2023.
- Hopeful developments this past year include a monumental global treaty to protect biodiversity on the high seas and the regulation of international trade in 97 species of sharks and rays under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
- At the same time, 2023 was the hottest year on record, with widespread bleaching of corals in the Caribbean and Great Barrier Reef, and many more hot years forecast as humanity’s emissions of greenhouse gases that cause global warming continue.

Con Chim: A window into Vietnam’s past and future beyond rice fields
CON CHIM, Vietnam —In response to escalating climate concerns, Vietnam is rethinking its approach to agriculture by reducing rice farming and adopting nature-based practices. Con Chim, once an overlooked region, is now emerging as a beacon of sustainable farming. Watch this video to learn more about how this transformation is setting a new standard for […]
Leveraging the hypothetical: The uncertain world of carbon credit calculations
- Criticisms of the voluntary carbon trade and forest conservation strategies like REDD+ have centered largely on the carbon accounting methods used to calculate credits.
- Each credit traded on voluntary markets is supposed to represent the reduction, avoidance or removal of 1 metric ton of carbon dioxide from the atmosphere.
- But recent science has raised questions about how REDD+ and other types of project figure out the number of tons of emissions saved.
- The process relies on establishing a baseline rate of deforestation against which a project’s emissions-reducing or -removing success is measured. But critics say the process can be faulty and that the conflicts of interest of the parties involved in setting the baseline have not been addressed until recently.
A Mekong island too tiny for industrial farming now points to Vietnam’s future
- In the decades following the U.S. war in Vietnam, the Vietnamese government championed intensive farming methods that boosted rice harvests and turned the country into an export powerhouse.
- While much of the Mekong Delta was reshaped to support intensive farming, the coastal island of Con Chim was deemed too small to be worth installing the necessary dikes and sluice gates, leaving farmers there to continue traditional patterns of wet and dry season agriculture and fishing.
- Now, in an era dominated by climate concerns, Vietnam plans to scale back rice farming and shift to more nature-based agricultural practices. Once a forgotten backwater, Con Chim now stands as a rare guidepost to a more sustainable agricultural future.

‘Cowboys’ and intermediaries thrive in Wild West of the carbon market
- A host of different players have crowded into the voluntary carbon trade as its value has grown.
- Motivated by the potential for profit, a concern for climate change or some combination of the two, these companies and organizations link the credits generated by projects, such as those that fit in the forest conservation scheme known as REDD+, with buyers, often companies and individuals in the Global North looking to compensate for their climate impacts.
- Some groups say they help shoulder the burden of tasks like marketing so that the communities and project staff on the ground can focus on the “change-making work.”
- But others, sometimes called “carbon cowboys,” seem interested in the money to be made from trading carbon. Some have faced allegations that they don’t bring the necessary expertise to their work, or that they don’t adequately inform local communities about the intended projects and the potential pitfalls.
Chile again rejects Constitution rewrite; experts say no big loss for environment
- On Dec. 17, 55% of Chilean voters rejected a proposal to reform the country’s Constitution, which dates back to the Augusto Pinochet regime; it was the second attempt, after a different proposal failed to get approval in September 2022.
- The latest proposed text, drafted mainly by conservatives, did not make significant progress on environmental and climate change topics, experts say.
- The 2022 draft included an entire chapter on the environment and made provisions on nature’s rights, while expanding protections against extractive industries. But concerns regarding the nationalization of water resources contributed to the “no” vote.
Do carbon credits really help communities that keep forests standing?
- Communities play a critical role in REDD+, a forest conservation strategy that aims to reduce emissions that can be sold as credits to raise money for forest protection.
- REDD+ projects often include components for the benefit of the communities, such as a focus on alternative livelihoods and provision of health care and education.
- But reports that REDD+ communities have faced abuses and rights violations have emerged recently in connection with high-profile REDD+ projects.
- Several Indigenous-led organizations have voiced their support for REDD+ because, they say, it provides an avenue to fund their climate-related conservation work, while other groups say it’s not the answer.
As Sri Lanka floods swell with climate change, so does human-crocodile conflict
- Sri Lanka is among the countries most vulnerable to climate change, with long drought spells, receiving intense rain during a shorter period with a marked increase in flood events.
- During flooding, crocodiles inhabiting rivers tend to reach land and move closer to human settlements, increasing the risk of encounters with people.
- The Nilwala River flows through southern Sri Lanka and recent flood events have increased croc encounters with humans in the Matara district and escalated threats to human safety, resulting in disaster management responses.
- During recent flooding events, no serious incidents linked to crocodiles were reported, but wildlife officials had to chase crocs away from riverbanks, highlighting the need for an immediate and durable solution for the human-crocodile conflict around the Nilwala River area.
Forest carbon credits and the voluntary market: A solution or a distraction?
- Voluntary carbon markets and forest carbon credits have faced widespread criticism that reached a zenith in 2023.
- Media reports detailed concerns about their dubious climate benefits, respect for communities and land rights, and their use by Global North companies to avoid the difficult task of decarbonizing their operations.
- Supporters of forest conservation strategies like REDD+ say that they can and should play a role, as healthy forests can absorb a significant amount of atmospheric carbon. They also say REDD+ brings much-needed funding to protect and restore forests, not only for their carbon, but because of the biodiversity and communities they support.
- As 2023 draws to a close, and with it the U.N. climate conference in Dubai (COP28), proponents of the voluntary carbon trade are working to increase the “integrity” of markets in ways they hope make them a viable tool to deal with climate change.
Indigenous Gurung farmers revive climate-resilient millet in Nepal
- Indigenous Gurung farmers in central Nepal are trying to revive the cultivation of an almost-forgotten, drought-resilient crop: foxtail millet.
- This hardy grain was traditionally farmed as a famine crop because it grows at a time of the year when farmers are finished harvesting other crops like rice, maize and wheat.
- With Nepal experiencing increasingly unpredictable changes in weather and droughts that affect their harvests, proponents say local crops like foxtail millet have the potential to help farmers adapt to the changing climate.
- Over the past seven years, organic farming of the crop has seen consistent growth, thanks to the help of a community seed bank.
Indigenous-led coalition calls for moratorium on terrestrial carbon trade
- The Pathways Alliance for Change and Transformation (PACT), a coalition of Indigenous, community and nonprofit organizations, published a paper in September 2023 calling for a moratorium on the forest carbon trade out of concern for the rights of Indigenous peoples and local communities.
- PACT says a pause in selling carbon credits is needed until protections for the land rights of these communities are laid out “explicitly, proactively, and comprehensively.”
- In December at the U.N. climate conference in Dubai, carbon markets experienced a setback after negotiators failed to agree on texts to articles in the 2015 Paris climate agreement meant to guide the carbon trade.
In 2023, Mongabay’s reporting fellows covered Earth amid crisis — and hope
- 2023 marked the first full year of Mongabay’s Conservation Reporting Fellowships, which are offered in both Spanish and English; journalists in the English-language program represented six countries in Africa, Asia and the Americas.
- The fellowships aim to fill gaps in global conservation reporting, as our planet faces the unprecedented crises of climate change, biodiversity loss and the prospects of surpassing the planetary boundaries within which human life on Earth may thrive.
- Look ahead to 2024 for much more to come, as Mongabay expands and our fellowships grow and evolve with us.
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.”
Science panel presents COP28 with blueprint for saving the Amazon
- Five policy briefs launched at the COP28 climate summit in Dubai highlight the critical challenges facing the Amazon Basin, as well as the immediate actions and solutions needed to ensure a sustainable future for the region’s ecosystems and the 47 million people living there.
- The reports, published by the Science Panel for the Amazon (SPA), a high-level science body, cover cross-cutting topics, from root causes of deforestation and rethinking Amazon infrastructure to restoration and finance solutions.
- Stressing the urgency of preventing the rainforest from crossing a tipping point into a dry scrubland, the panel calls for leveraging nature-based solutions and Indigenous knowledge to consolidate new social bioeconomies that can “leave forests standing and rivers flowing.”
- Based on a previous SPA brief, Brazil launched Arcs of Reforestation, a $205 million program to restore 6 million hectares (15 million acres) of deforested and degraded forest land in some of most affected parts of the Brazilian Amazon.
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.
NGOs at COP28 demand Vietnam free climate advocates before it gets energy funding
- Vietnam has unveiled the resource mobilization plan for its just energy transition partnership (JETP) at the COP28 climate summit in Dubai.
- The $15.5 billion plan, a partnership between Vietnam and G7 countries, outlines the policies and financing Vietnam will need to achieve 47% renewable energy and peak emissions in 2030.
- Environmentalists are calling for Vietnam to release imprisoned climate activists and guarantee protections for civil society before the JETP can move forward.
- In the past two years, Vietnam has imprisoned six leading environmental advocates, including individuals working on alternatives to fossil fuel expansion.
Thailand tries nature-based water management to adapt to climate change
- With an economy largely underpinned by irrigated crops like rice, water is a crucial resource in Thailand. But as climate change exacerbates floods and droughts in the country, sustainable water management is an increasing challenge.
- Nature-based solutions that incorporate the natural processes of the country’s abundant rivers, floodplains and watershed forests are beginning to be trialed via various projects at large and small scales.
- A new report assesses the efficacy of two nature-based approaches to water management in Thailand, which represent a step away from the country’s typically top-down, hard-engineering approach and present several benefits to the environment and communities.
- However, environmental and societal tradeoffs, complex policy frameworks, and the need for greater understanding and expertise around the concept, design and implementation of nature-based approaches are barriers to their widespread implementation.
Climate loss & damage fund ‘the furthest thing imaginable from a success’
- The fifth and final meeting of the U.N. Transitional Committee to design a loss and damage fund ahead of COP28 climate summit concluded in Abu Dhabi last month without a mandate that wealthy, industrialized nations pay into it, sources say.
- Frequent Mongabay contributor and journalist Rachel Donald joins the Mongabay Newscast as co-host to speak with Brandon Wu, director of policy and campaigns at ActionAid USA, to unpack this most recent negotiation.
- In addition to leaving out a provision for contributions from wealthy nations, the fund will be housed in the World Bank, a global lending institution that continues to fund coal projects and has been linked to human rights abuses.
- The text of the fund will move to the 2023 United Nations Climate Change Conference (COP28) in Dubai next month, where it will be considered by member countries.
Can impermanent carbon credits really offset forever emissions?
- A team of researchers has put forth a method that they say makes it possible to compare credits for carbon from forests projects against more permanent storage solutions.
- The carbon emissions that these credits are meant to offset can last for hundreds, if not thousands, of years in the atmosphere. Forests, by comparison, are subject to fires, disease and deforestation, meaning that their climate benefits can be more temporary than longer-term solutions, such as direct air carbon capture.
- By “discounting” the credits from forest carbon projects based on conservative upfront estimates of how long a forest will safeguard or sequester carbon, the authors say that “like-for-like” comparisons would be possible.
- The team published their work Oct. 30 in the journal Nature Climate Change.
Salty wells and lost land: Climate and erosion take their toll in Sulawesi
- Coastal erosion on the west coast of Indonesia’s Sulawesi Island is so advanced that seawater has penetrated the groundwater supply that tens of thousands use for drinking water.
- The communities have yet to be served by utility water provision, so families are resorting to costly supplies of water from private distributors.
- Research shows that rising seas and more frequent and powerful storms will accelerate coastal abrasion, raising burdens shouldered by the world’s coastal communities.
Carbon counting without the guesswork: Q&A with FCL proponent Jerry Toth
- REDD+ projects aim to incentivize efforts that maintain standing forests, rather than cutting them down, by providing payments based on the carbon emissions kept out of the atmosphere.
- But REDD+, which is short for “reducing deforestation and forest degradation in developing countries,” has been widely criticized lately, in part because skeptics say that the accounting methods are open to manipulation by developers aiming to sell more credits — credits that many not represent a verifiable climate benefit.
- One alternative is the forest carbon ledger (FCL). FCL seeks to value the total amount of carbon in a forest and would provide payments based on how well that storage is maintained over time.
- Mongabay spoke with Jerry Toth, co-founder of a conservation group working to protect and restore the last remaining remnants of the Pacific Forest of Ecuador called the Third Millennium Alliance (TMA). Toth said FCL may provide a more robust alternative to REDD+ carbon accounting.
Is ocean iron fertilization back from the dead as a CO₂ removal tool?
- After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to remove “gigatons per year” of carbon dioxide from Earth’s atmosphere.
- The idea behind ocean iron fertilization is that dumping iron into parts of the ocean where it’s scarce could spark massive blooms of phytoplankton, which, when they die, can sink to the bottom of the sea, carrying the CO₂ absorbed during photosynthesis to be sequestered in the seabed for decades to millennia.
- So far, proof that this could work as a climate-change solution has remained elusive, while questions abound over its potential ecological impacts.
- Scientists with the Woods Hole Oceanographic Institution in Massachusetts, U.S., recently received $2 million in funding from the U.S. government that will enable computer modeling research that could pave the way for eventual in-ocean testing, effectively reviving research into ocean iron fertilization.
Forests hold massive carbon storage potential — if we cut emissions
- A new study finds forests could potentially store 226 billion metric tons of carbon if protected and restored, or about one-third of excess emissions since industrialization.
- Nearly two-thirds of this potential lies in conserving and letting existing forests mature.
- The authors say that restoring deforested areas through community-driven approaches such as agroforestry and payments for ecosystem services is essential.
- Planting trees can’t replace cutting fossil fuel emissions, as climate change threatens forests’ carbon uptake.
In Borneo, the ‘Power of Mama’ fight Indonesia’s wildfires with all-woman crew
- Wildfire poses significant health risks to Indonesians, particularly children under 5, who especially suffered the effects of the 2019 haze.
- Farmers have long used fire in cultivation, and the risks to health and environment have grown significantly as deforestation and drainage have made peatlands particularly susceptible to fire.
- In 2022, women from the Indonesian part of Borneo formed “the Power of Mama,” a unit to fight hazardous wildfires and their causes.
Critical questions remain as carbon credit deal in Sabah presses forward
- Details around a secretive “nature conservation agreement” signed in 2021 between a Singaporean company and the government of Sabah, a Malaysian state on the island of Borneo, remain elusive.
- Several internationally known companies that work in climate mitigation have said they’re not affiliated with the agreement, despite implications by Jeffrey Kitingan, a deputy chief minister and the deal’s primary backer, that they are involved.
- Kitingan also revealed that Hoch Standard, the Singaporean company, is controlled by a single director through another company registered in the British Virgin Islands.
- Kitingan said the project is moving forward, leading to renewed calls from civil society, Indigenous and research organizations for the release of more details about the agreement.
Battling desertification: Bringing soil back to life in semiarid Spain
- Southeastern Spain is experiencing the northward advance of the Sahara Desert, leading to declining rainfall, soil degradation, and climate change-induced droughts, threatening agricultural lands that have been farmed for many centuries.
- Local farmers recently began adopting regenerative agriculture practices to better withstand long, persistent droughts punctuated by torrential rains and subsequent runoff.
- Many farmers in the region have formed a collaborative group called Alvelal to address encroaching desertification, depopulation, and the lack of opportunities for youth.
- Alvelal members manage more than 15,000 hectares (37,000 acres) of farmland using regenerative agriculture techniques and aim to expand further, conserving more farmland against the onslaught of climate change, while restoring natural corridors and promoting biodiversity.
Meet the farmers in southeastern Spain fighting desertification
LOS VÉLEZ, Spain — Southeastern Spain faces a pressing environmental challenge: the encroachment of the Sahara Desert. This northward advance results in reduced rainfall, soil degradation, and severe droughts driven by climate change, jeopardizing centuries-old agricultural lands. In response to these challenges, local farmers are increasingly turning to regenerative agriculture practices. These innovative methods aim […]
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.
Kenya’s Lake Victoria floods leave orphaned children to run their households
- Beginning in 2019, devastating floods on the shores of Kenya’s Lake Victoria have inundated homes, displaced families and left some orphaned children in charge of caring for their siblings and running the household.
- Many families continue to live in makeshift camps, hoping to rebuild and renew their lives; the effects of the flooding have been particularly harsh on children who have had to drop out of school or work to ensure the family’s survival.
- Experts attribute the floods to a combination of factors, including climate change, increased rainfall and lack of vegetation to control runoff; in 2015, an international research team predicted swiftly rising waters that could harm the region.
- UNICEF reports a concerning increase in the number of children affected by flooding in recent years, as climate change leads to more crises that can disrupt education, destabilize families and leave long-term effects on child development and psychosocial well-being.
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.
Calls for crackdown intensify as fire crisis heats up across Indonesia
- A senior member of Indonesia’s parliament has called for tougher law enforcement as firefighters continued to battle wildfires across the archipelago.
- Indonesia’s environment ministry says it had sealed off 35 land concession, including several oil palm concessions, in the year to date.
- The fires are also fueling a diplomatic spat with neighboring Malaysia, which blames poor air quality there on the haze blowing from fires in Sumatra and Borneo.
Seaweed: The untapped economic potential for Bangladesh
- Bangladesh currently produces some 400 tons of seaweed, valued at 55 million taka (about $500,000), while a study suggested the country could produce 50 million tons of seaweed annually by 2050.
- Despite the potential to grow and earn more foreign currency through export, the sector is dealing with a number of difficulties, including inadequate investment as well as proper guidelines and regulations.
- According to the Food and Agriculture Organization (FAO), seaweed farming is one of the fastest-growing aquaculture sectors globally, with an annual production of about 33 billion tons, valued at $11.8 billion.
Microplastics pose risk to ocean plankton, climate, other key Earth systems
- Trillions of microplastic particles in the ocean threaten marine life, from huge filter-feeders to tiny plankton. Although not lethal in the short term, the long-term impacts of microplastics on plankton and marine microbes could disrupt key Earth systems such as ocean carbon storage and nitrogen cycling.
- Oceans represent Earth’s largest natural carbon store and are crucial to mitigate atmospheric CO2 increase. Carbon taken up by plankton and stored in the deep ocean — known as the biological carbon pump — is a major process in ocean carbon storage. Microplastics may “clog” this pump and slow ocean carbon uptake.
- Microplastics in marine sediments alter microbial communities and disrupt nitrogen cycling, potentially magnifying human-caused problems like toxic algal blooms. Changes in plankton communities at the ocean surface could exacerbate deoxygenation driven by climate change, starving marine organisms of oxygen.
- Small plastic particles are impossible to remove from the oceans with current technology, so stopping pollution is a priority. Plastic production continues to soar year-on-year, but a U.N. treaty to address plastic pollution could offer a glimmer of hope that the international community is ready to take action.
Return of the wolf to Nepal’s Himalayas may threaten snow leopards
- The return of wolves to Nepal’s Himalayan region is putting greater pressure on populations of naur, or blue sheep — and by extension on snow leopards, whose main prey is naur.
- New research shows that naur tend to exhibit greater vigilance in areas where both wolves and snow leopards are present, while lowering their guard somewhat when no wolves are around.
- Conservationists say the growing wolf presence threatens snow leopards through direct competition for food and through stressing out, and weakening, naur populations.
- Snow leopards already face pressure from common leopards and tigers, which are moving further uphill in response to both human threats and a changing climate.
Salinity hinders Bangladesh agriculture; groups respond with seeds & information
- Bangladesh is the fourth-highest rice-producing country in the world, but much of that production is threatened by salinity.
- More than 30% of the cultivable land in Bangladesh is in the coastal area; a comparative study of the salt-affected area showed that of 2.86 million hectares (7.1 million acres) of coastal and off-shore lands, about 1.056 million hectares (2.6 million acres) — an area roughly the size of Lebanon — of arable lands are affected by varying salinity, hampering agricultural production.
- In the coastal zones, farmers mainly cultivate low-yielding, traditional rice varieties during the wet season, while in the dry season (January- May), most of the land remains fallow because of soil salinity.
- To cope with the situation, government and nongovernmental organizations are introducing different types of saline and extreme weather-tolerant crop varieties to use the farmland yearly.
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.
Climate change detectable in daily rainfall patterns, deep-learning model finds
- Researchers have developed a deep-learning AI model that predicts how global warming is affecting daily precipitation patterns around the world.
- Using the model, scientists found that every year since 2015 daily rainfall deviated from natural variability at least 50% of the time as a result of rising temperatures.
- Research has long focused on climate change’s long-term impacts such as annual temperature increase or precipitation rates.
- However, studies in recent years have observed how rising temperatures are altering daily weather patterns as well.
DRC food sovereignty summit yields support for agroecology, local land rights
- The Alliance for Food Sovereignty in Africa (ASFA) recently held a meeting in Kinshasa to argue for the reorienting of food production around agroecology in the Congo Basin.
- Civil society groups, donors, government representatives and small-scale farmers gathered to exchange views on challenges and solutions to food security.
- Across Africa, agricultural policy is geared toward greater reliance on large-scale farms and mechanization, commercial seeds, pesticides and synthetic fertilizer.
- A declaration issued at the close of the summit instead called for investment in agroecological methods, as well as recognition of and protection for Indigenous and local peoples’ land rights.
Agroecology alliance calls for more food at less cost to nature in Congo Basin
- The Alliance for Food Sovereignty in Africa (AFSA) will make the case for reorienting food production systems and agricultural policy at a meeting in Kinshasa from Aug. 29-31.
- Food security across the Congo Basin is threatened by impoverished soils, climate change, and displacement due to armed conflict, forum attendees say.
- Governments in the region back improved seeds and synthetic fertilizer for small-scale farmers as well as large-scale agriculture projects to boost yields and revenue.
- AFSA argues these strategies cause more harm than good to both farmers and forests, and calls for a turn to agroecological methods instead.
REDD+ projects falling far short of claimed carbon cuts, study finds
- New research reveals that forest carbon credits are not offsetting the vast majority of emissions that providers claim.
- A team of scientists looked at 26 REDD+ deforestation-prevention project sites on three continents, leading to questions about how the developers calculate the impact of their projects.
- The researchers found that about 94% of the credits from these projects don’t represent real reductions in carbon emissions.
- Verra, the world’s largest carbon credit certifier, said the methods the team used to arrive at that conclusion were flawed, but also added it was in the process of overhauling its own REDD+ standards.
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.
Bali rice experiment cuts greenhouse gas emissions and increases yields
- Rice paddies are responsible for 11% of the world’s methane emissions. There are more than 200 million rice farms in Asia.
- Working with local farmers, researchers in Bali, Indonesia, have discovered how to dramatically reduce the greenhouse gas emissions output of rice fields. Initial indications are showing a 70% reduction.
- The farming breakthrough also boosted the yield of crops and reduced the amount of pesticides flowing to coral reefs.
Study shows how to maximize mangroves as climate and community solution
- Mangroves’ high carbon storage capacity can help countries meet their carbon emission reduction targets under the Paris Agreement, while also producing benefits for local communities.
- Recent research using data from Belize has quantified mangrove carbon storage and sequestration potential and identified where the country should prioritize conservation and restoration to maximize ecosystem services that would benefit multiple sectors.
- The research has been used by Belizean authorities to update national climate targets, committing to protect an extra 12,000 hectares (30,000 acres) of mangroves and restore another 4,000 hectares (10,000 acres) by 2030, which could provide an example for other national blue carbon strategies.
- The study also took into account the point where mangrove protection and restoration begin to offer diminishing returns, which would allow authorities to adjust the ambition of climate mitigation and adaptation via mangroves.
In Philippines, climate change tests Indigenous farming like never before
- In the uplands of the Philippines’ Iloilo province, Indigenous Suludnon farmers maintain deep connections to the agroecosystem that has sustained their community for generations.
- Agroforestry systems and diversified planting have helped the Suludnon cope with a changing climate, and traditional knowledge of natural signs of hazardous weather have allowed them to prepare for storms.
- However, with climate change bringing increasingly frequent extreme weather events, along with crop pests and disease, the Suludnon’s time-refined methods are coming under strain.
Massive carbon offset deal with Dubai-based firm draws fire in Liberia
- According to a draft contract seen by Mongabay, Liberia may sign away the rights to nearly 10% of its total land mass to a United Arab Emirates-based firm for carbon offset development.
- The firm is owned by Ahmed Dalmook Al Maktoum, the youngest member of Dubai’s royal family and an investor in energy projects across Africa and the Middle East.
- Environmental groups in Liberia say the deal could violate multiple laws, including those meant to protect community land rights.
- The deal comes as the UAE prepares to host the COP28 climate conference, where rulemaking around carbon markets will be a hot agenda item.
Progress is slow on Africa’s Great Green Wall, but some bright spots bloom
- Africa’s ambitious Great Green Wall, a mosaic of reforestation efforts to stop desertification, has been plagued by delays and challenges.
- Some reforestation efforts, however, have tasted success, becoming a model for many to follow.
- Experts suggest moving away from viewing the initiative as merely a tree-planting exercise and instead seeing it as a holistic, participatory approach that involves local communities and helps them build their livelihoods and incomes.
- Challenges still abound, however, including a volatile security situation, lack of water, coordination challenges, and scattered long-term monitoring of reforested patches.
Morocco rolls out a phosphorous-fueled plan to heal soils across Africa
- Farmers across Africa are faced with eroded, phosphorus-limited soils, leading to low crop yields, despite having some of the world’s richest phosphate deposits in Morocco.
- Soil scientists at Mohammed VI Polytechnic University in Morocco are building a countrywide network of farmers and soil experts to routinely test soil for its nutrients and other properties, giving farmers more tailored fertilizer recommendations.
- Morocco is the first country in Africa to create soil fertility maps, a way to map out the productivity of arable land, with the practice now catching on in other countries.
- Researchers and others in the agriculture sector see Morocco as a potential leader in boosting soil productivity and revolutionizing agriculture in Africa to expand production beyond subsistence farming.
Vietnamese rice farmers go high-tech to anticipate a low-water future
- Since the 1970s, Vietnam’s “rice-first” policy facilitated the construction of an elaborate series of dikes and dams that allowed farmers in the Mekong Delta to flood their fields to allow for multiple harvests per year.
- Now, in the face of climate change impacts, seawater intrusion, upstream dams and new government policies that mandate water conservation, farmers in the delta need to find ways to reduce their water consumption.
- In one pilot project, university researchers have teamed up with local farmers to implement a technique called alternate wetting and drying (AWD), supported by a smartphone application that allows farmers to save water and reduce emissions.
Green gains: Localized efforts leave a mark, notably in drier areas, study shows
- Spurts of green spread across the African continent taken together accounted for over 400,000 square kilometers (154,000 square miles) of greening, an area the size of Zimbabwe.
- According to researchers, it’s important to distinguish how much of this greening is due to human efforts and how results much from broader climatic shifts.
- The team compared greening trends in target plots with neighboring plots; the latter, they hypothesized, would reflect changes in vegetation driven by broader climatic trends.
- Despite these advances, satellite imagery-based monitoring of vegetation growth can be a blunt instrument, especially where the data don’t capture differences in the greening, like those arising from agricultural expansion or reforestation.
Drought cycles erode tropics’ ability to absorb CO₂, study finds
- A recent study finds that tropical carbon sinks have become increasingly vulnerable to water scarcity since 1960, and are consequently less able to absorb carbon dioxide.
- These findings suggest that tropical ecosystems are less resilient to climate change than previously thought.
- While the study doesn’t necessarily make projections for the future, the findings suggest that an acceleration of climate change, which is very likely to bring more drought, could further limit the ability of tropical ecosystems to absorb carbon dioxide, which, in turn, would worsen climate change.
On burning-prone Borneo, planners work to fireproof Indonesia’s new capital
- The developers of Indonesia’s new capital city, Nusantara, have begun preparations to protect the site from the threat of wildfires and smoke pollution.
- City planners are to launch drones to monitor the estate for wildfires and hope to operate a dedicated fire brigade from next year.
- Nusantara faces lower wildfire risks owing to its east-coast location and distance from Borneo’s flammable peatlands, but officials nonetheless stress the need to build an early-warning system for wildfires around the site.
Can Spain keep the rising sea from washing away a critical delta?
- One of Europe’s most important deltas, a vital wildlife sanctuary and economic engine, is facing a myriad of threats stemming from climate change and water management.
- Rising sea levels and stronger storms are washing away the very sediment that constitutes the Ebro Delta and sending saltwater far inland.
- The government plan to bolster the delta relies heavily on trucking sediment to its exposed outer banks, but it’s a stop-gap measure until researchers can develop a more sustainable long-term solution.
- The question is: Can they find one in time?
Jokowi focuses on El Niño as Indonesia’s dry season heats up
- Indonesian President Joko Widodo warned officials to anticipate risks from the first El Niño since the 2015 Southeast Asia wildfires crisis.
- Dry season conditions had emerged in 52% of Indonesian territory by early July, according to the country’s weather forecaster.
- Officials hope reforms enacted since the 2015 disaster will lessen the severity of wildfires as El Niño conditions become more pronounced.
With El Niño likely, Indonesia’s volunteer firefighters gear up — with new gear
- More than 11,000 community firefighters across Indonesia are readying for a likely El Niño year, better prepared than ever before.
- One community outfit of five volunteers in Sumatra’s province is monitoring the local peatland with the help of a drone procured from the village budget.
- Officials hope that a legal crackdown on farmers burning combined with improved community capacity can limit wildfires this year.
Big potential and immense challenges for great ape conservation in the Congo Basin, experts say
- Great apes are on track to lose 94% of their range to climate change by 2050 if humans do nothing to address the problem, according to research.
- In the great apes stronghold of the Congo Basin, national interests in natural resource exploitation, a lack of security in areas like the Albertine Rift, hunting, and the illegal wildlife trade all greatly impact populations of bonobos and mountain gorillas.
- In this episode of Mongabay Explores, Gladys Kalema-Zikusoka, Kirsty Graham, Terese Hart, and Sally Coxe speak with Mongabay about the threats to bonobos and mountain gorillas, the lessons learned from decades of conservation efforts, the importance of great apes for the protection of Congo Basin rainforest, and ways forward for conservation as well as livelihoods for Indigenous and local communities.
Extreme temperatures and erratic weather disrupt Bangladesh’s famous Rajshahi silk industry
- Since the 13th century, Rajshahi, named “Silk City,” has been known for its finest silk, which local growers have produced.
- Earlier, the product was named Bengal silk or Ganges silk. Considering the prospects and reputation of the trade, the then-Pakistan government started producing silk officially. Consequently, it established a silk factory in Rajshahi in 1961, which washanded over to Bangladesh Sericulture Development Board in 1978.
- The silk sector in Rajshahi grew as farmers of the neighboring districts used to produce high-quality silk yarns by the larvae of moths fed on fresh mulberry leaves, which were later used for luxurious clothing items. There are three types of silk produced in Rajshahi: mulberry, endi and tassar, with mulberry silk being the finest and most expensive.
- However, Bangladesh’s once-famous silk industry has faced difficulties in recent years, including the excessive dependency on imported low-cost yarn and different bacterial and viral diseases triggered by constantly variable temperatures and humidity.
Bangladesh’s new red list of plants shows country has already lost seven species
- Bangladesh’s first-ever red list of plant species shows the country has lost seven species in the last century and now risks losing at least another five.
- Researchers involved in the assessments of the conservation status of 1,000 species cited climate change, pollution, deforestation, and poor management of protected areas as major drivers behind the ecological damage.
- The Bangladesh Forest Department is working to protect native plant species through large-scale planting efforts across the country.
For Central America, climate bill could top hundreds of billions annually
- Climate change impacts on Central America’s forests could cost the region between $51 billion and $314 billion per year by 2100, according to a new study.
- For some of the countries in region, the loss of ecosystem services provided by forests could lead to losses equivalent to more than three times their GDP.
- This is the first time ecological and economic measurements have been assessed together for climate change impacts in Central America and could help to inform conservation activities like defining protected areas, establishing biological corridors and restoring degraded landscapes.
- While the impacts of climate change are being felt by communities in the region, breakthroughs in computing power as well as collaborations between European universities and Central American research institutions and companies is promoting increased innovation in ecosystem restoration.
Climate change, human pressures push Bangladesh’s ‘national fish’ into decline
- Bangladesh’s all-important hilsa fishery is declining amid pressures from human-driven factors and climate change, experts and authorities warn.
- The fish, Tenualosa ilisha, contributes around 12% of the total fish catch in Bangladesh, and the fishery employs at least 2.5 million people across the country.
- Several government conservation initiatives, including declaring six hilsa sanctuaries and two fishing bans during the year, have helped boost production in the past two decades.
- However, pressures persist, including rising salinity levels in the rivers where the fish spawn, discharge of pollution and agricultural runoff, and disruptions to water flow as dams are built upstream.
Penguins ‘enrich our lives’: Q&A with Pablo Borboroglu, protector of penguins
- Pablo Garcia Borboroglu, a marine biologist from Patagonia, Argentina, was recently awarded the 2023 Indianapolis Prize for his work in protecting penguins around the world.
- Penguins face many threats, including pollution, human disturbance, and the impacts of fisheries and climate change.
- Borboroglu has helped protect penguins through various actions, including establishing marine and terrestrial protected areas, conservation research programs, and educational programs.
Southern African caterpillar that feeds millions may be next climate casualty
- A new study projects a significant loss of habitat for an edible caterpillar, known as the mopane worm, in Southern Africa in the coming decades.
- Mopane worms are a key source of seasonal protein for millions of people throughout Southern Africa, but they also face pressures from overharvesting and deforestation.
- Species distribution models devised by a group of scientists project that even under a moderate climate change scenario, some regions will lose 99% of suitable habitat for the caterpillars.
- The scientists behind the study say their projections should be seen as a call to protect regional food security by preventing both climate change and biodiversity loss.
In Chile, a wildlife rehab center deals with the aftermath of worsening fires
- Wildfires at the beginning of this year in Chile were some of the deadliest on record, destroying nearly 500,000 hectares (1.2 million acres) of land and killing people and wildlife.
- At a wildlife rescue center in the city of Chillán, volunteer vets have been treating wildlife brought in with burns and other injuries, and releasing them back into their habitat wherever possible.
- But with much of the wildlife habitat severely damaged by the fires, the number of locations fit for wild rereleases is limited.
- Ecologists blame the intensifying fires on the combination of climate change, the spread of fire-prone eucalyptus and confer plantations, and deliberate burning.
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.
Climate warming alters offspring production of birds, study shows
- A global meta-study investigating the effects of climate change on bird reproduction has found an overall decline in annual offspring production over 50 years.
- Offspring production in migratory and large birds decreased, whereas it increased in smaller-bodied and sedentary species.
- Migratory species may find it difficult to adapt to a rapidly changing climate in their breeding and wintering areas. Large birds may have problems adapting to changing climate conditions because they tend to live a ‘slower pace of life’ and have offspring only once a year.
- Curbing our carbon dioxide emissions will halt rising temperatures impacting bird species, say the study’s authors. People can also help boost bird reproduction by creating a cooler environment for bird nests in yards and parks through dense vegetation during heat waves.
Africa’s land and forest restoration initiative gathers pace in Malawi
- In 2015, African countries launched the African Forest Landscape Restoration Initiative (AFR100), committing to restore 100 million hectares (250 million acres) of degraded forests and landscapes by 2030.
- A June 2022 progress report on the initiative showed that nations had put 917,014 hectares (2.27 million acres) under restoration between 2016 and 2021, 63% of that as agroforestry.
- Malawi, which has committed to restoring 4.5 million hectares (11.1 million acres) by 2030, is seen to be making progress with a raft of frameworks formulated to support the initiative and more partners joining the cause, building on some previous interventions.
- Experts insist there needs to be decisive action to tackle deforestation, which they say is a significant threat to the restoration initiatives in Malawi.
Protected areas store a year’s worth of CO₂ emissions, study reveals
- Researchers analyzed never-before-used satellite data to calculate how much carbon is stored in protected areas worldwide.
- The Amazon Rainforest’s protected areas accounted for the highest rate of carbon stock, according to the unprecedented study.
- The results can help policymakers and conservationists assess areas for protection to fight climate change — and not just forests.
Deforestation linked to less rainfall, study shows; El Niño could make it worse
- A new study shows concerning links between deforestation and reduced precipitation in tropical regions, which can in turn lead to reduced agricultural yields and food security issues.
- Now, researchers are concerned about the potential for another El Niño, which typically brings hotter, drier conditions to tropical regions, particularly in Southeast Asia, and can compound the effects of deforestation and reduced rainfall.
- The 2015-16 El Niño triggered crop losses, disease outbreaks, malnutrition and food insecurity, livestock deaths and other hardships that affected 60 million people globally; researchers say these trends signal the need for greater climate resilience in local communities.
Expedition to Pacific ecosystems hopes to learn from their resilience
- An expedition led by National Geographic’s Pristine Seas project will voyage across the Pacific over five years to gather information about marine ecosystems needing protection.
- The Pristine Seas team will collaborate with Pacific island nation governments, communities, Indigenous and local peoples, and local scientists, to gather data and produce films.
- The first stop of the expedition will be the southern Line Islands, part of Kiribati, to understand how its reefs recovered after an El Niño triggered a large-scale bleaching event in 2015 and 2016.
Head of Verra, top carbon credit certifier, to leave in June
- David Antonioli is the founding CEO of Verra, the world’s most prominent carbon credit standards organization.
- Antonioli will leave the post in June amid increasing scrutiny of carbon markets and credits, as well as the methodologies by which they are certified to ensure they provide climate benefits that do not come at the expense of communities.
- Indigenous groups and forest communities are often key participants in restoration and protection efforts to boost carbon sequestration.
- But they say that little of the financing for climate mitigation flows directly to them, and they also want a more prominent role in the discussions about climate change mitigation projects and the future of mechanisms like carbon credits and markets.
Climate change is no joke for Australians, says award-winning comedian Dan Ilic
- Despite citizens voting out the Scott Morrison-led government of Australia in 2022, Dan Ilic says there’s still a lot of talk around climate change policy with not enough action to meet national climate targets.
- Known widely for his epic billboards appearing in New York’s Times Square during the COP26 climate summit satirizing Australia’s lack of seriousness at the conference, Ilic is host of the award-winning Australian comedy/climate-focused podcast “A Rational Fear” and spoke with the Mongabay Newscast in Sydney about the landscape surrounding climate policy in the country today.
- He also shares his thoughts on victories for Indigenous communities in the Tiwi Islands and the Galilee Basin, both in Australia, where massive fossil fuel proposals were recently blocked.
Melting Arctic sea ice is changing bowhead whale migrations, study finds
- Research has found that some bowhead whales in the Bering–Chukchi–Beaufort (BCB) population are no longer migrating to the northwestern Bering Sea in the winter but remain in the Canadian Beaufort Sea.
- These migratory shifts are occurring as sea ice declines in the region due to climate change.
- These changes could mean that bowhead whales become more susceptible to ship strikes, underwater noise, and entanglements, and that Indigenous communities may not be able to rely on bowhead whales for nutrition and cultural subsistence.
- However, this bowhead population is currently not threatened, and these changes may not be fully impacting Indigenous communities yet.
An Asian grass helps Mexican farmers build resilience to climate change
- A longtime ingredient in fragrances, vetiver is becoming an ally for farmers facing the impacts of climate change.
- Planting vetiver grass in tropical and subtropical regions is a cheap and simple way to prevent soil erosion, capture carbon dioxide and detoxify the soil, with this nature-based solution already in use for decades in India and now becoming increasingly popular elsewhere.
- In Mexico, where 76% of the land suffers from erosion, one environmental expert in Veracruz state has become a pioneer in using vetiver to stop soil erosion.
- The method used on a tobacco farm helped reduce crop loss and improve harvests significantly in just its first year of implementation.
Studies show oyster reef restoration can work out well — given enough time
- Researchers have found that the restoration of eastern oyster (Crassostrea virginica) reefs in the U.S. have been largely successful, improving oyster production, enhancing habitat, and increasing nitrogen cycling.
- They also found that oyster restoration was more successful in deeper, saltier parts of coastal waters and that it generally took at least eight years for restored reefs to yield long-term benefits.
- But since the 1800s, more than 85% of global reefs have disappeared due to overfishing, disease and other anthropogenic pressures.
- Researchers say their findings can help restoration managers identify which ecosystem services can benefit from their work, how long those benefits might take to accrue, where to construct oyster reefs.
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.
Organic farming, and community spirit, buoy a typhoon-battered Philippine town
- After their town was devastated by floods in 2004, residents of Kiday in the Philippines shifted to organic methods when rebuilding their farms.
- Today, the Kiday Community Farmers’ Association practices agroecology and agroforestry, maintaining communal plots as well as private gardens.
- The association receives nonprofit support, but government funding continues to prioritize conventional agriculture over more sustainable methods.
- Farmers in Kiday also face a new threat in the form of the government-supported Kaliwa Dam, which is under construction upstream of the village.
