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.

Warming climate threatens to worsen air quality in already polluted Kathmandu
- In the period between winter and spring each year, Kathmandu faces severe air pollution that affects thousands of residents with health problems like burning eyes, respiratory discomfort, and even death.
- Local sources like vehicle emissions and construction dust, compounded by Kathmandu’s geography, are the main drivers of the pollution, and rising global temperatures threaten to worsen the situation.
- Changes in weather patterns, including reduced rainfall and prolonged dry periods are among the changes that could make air pollution an even more severe problem than it already is.
- Wildfires, both natural and human-induced, contribute significantly to air pollution in Kathmandu, especially during the transition period between weather systems, which could become longer due to rising temperatures.

As fires ravaged Indonesia in 2023, some positive trends emerged, data show
- Indonesia’s 2023 fire season saw 1.16 million hectares (2.87 million acres) of land and forest go up in flames, and while this was five times higher than in 2022, experts highlight a positive trend.
- The fires were exacerbated by an intense El Niño weather system, unlike in 2022; the last time similar conditions prevailed, in 2019, the area affected by fires was much larger, suggesting fire mitigation efforts may be working.
- Most of the burning occurred in scrubland and areas of degraded forest rather than in intact forests, meaning greenhouse gas emissions from the burning were also much lower than in 2023.
- But a worrying trend highlighted by the numbers is that severe fires are now occurring in four-year cycles, intensified and exacerbated by the impacts of a changing climate.

Agroforestry project sows seeds of hope in drought-hit Honduras
- In response to longer and more intense droughts, Indigenous Tolupan farmers in Honduras are turning to agroforestry and agroecology strategies to adapt to the changing climate.
- The strategies include diversifying their crops, building water storage systems, introducing methods to better conserve water in the soil, and building up banks of native seeds.
- Although Honduras wasn’t among the 22 countries that declared a drought emergency in 2022 and 2023, severe heat waves and El Niño events are hitting harvests hard, leading to an exodus of young people out of rural areas.
- Locals participating in the adaptation initiative say it’s starting to bear fruit and give them hope — a precious resource in a dry land.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Australia bushfires may have caused global climate phenomenon La Niña: Study
- The 2019-2020 Australian bushfires threw up so much ash into the atmosphere that it resulted in a cooling of the southern Pacific and hence a La Niña climate phenomenon, a new study says.
- Volcanic eruptions that send vast ash plumes into the atmosphere are thought to trigger La Niña events, but this is the first time a fire has been recorded as doing so.
- La Niña can produce ruinous weather conditions in contrasting ways, from additional hurricanes in North America and droughts in the Horn of Africa, to crop failures in South America.
- The study’s findings call into question the assumption in current climate models that biomass emissions — including from bushfires — will decrease over time.

‘Alarming’ heat wave threatens Bangladesh’s people and their food supply
- Temperatures across Bangladesh have hit record highs as the country swelters in the heat wave currently sweeping across much of Asia.
- Dhaka recorded its highest temperature in six decades this month, at 40.6°C (105.1°F), with meteorologists warning that heat waves like this are becoming more common.
- The heat also threatens the country’s all-important rice crop, with the government advising farmers to ensure sufficient irrigation to prevent heat shock to their plants.
- With the heat now easing, a new fear has emerged: Cooler temperatures signal the start of the monsoon, which, in the northeast region of Bangladesh often means floods that can also destroy rice crops.

Feathered forecast: Tech tools comb weather data for bird migrations
- Since its launch in 1999, the BirdCast project has used weather radar data to track and forecast bird migrations across the U.S.
- In recent years, technology such as cloud computing and machine learning have helped make the work of researchers in the project easier and more automated.
- Studying bird migrations is essential not only to help protect them, but to also analyze and understand environmental health.
- The BirdCast project is now working on integrating radar data with human observations and bioacoustics to help identify the bird species traversing the skies.

Southern atmospheric rivers drive irreversible melting of Arctic sea ice: Study
- Arctic sea ice extent has reached its winter maximum extent for 2023 at 14.62 million sq. km., the fifth lowest on record. Combined with this year’s unprecedentedly small Antarctic sea ice summer minimum extent, global sea ice coverage reached a record low in January.
- Arctic sea ice is not only receding, but also seriously thinning. New research has found that a huge melt in 2007 and associated ocean warming kicked off a “regime shift” to thinner, younger, more mobile and transient ice that may be “irreversible.”
- A big reason why Arctic sea ice is declining even in the frigid polar winter is that atmospheric rivers, which carry warmth and rainfall like the deluges seen in California recently, are surging up from the south and penetrating the Arctic more often.

Carbon uptake in tropical forests withers in drier future: Study
- A new study incorporating satellite data on organic material, or biomass, in tropical forests with experimental data about the effects of temperature and precipitation suggests that forests may lose substantial amounts of carbon by the end of the 21st century.
- Even with low continued carbon emissions, tropical forests, especially those in the southern Amazon, could lose between 6.8 and 12% of their aboveground carbon. With higher emissions, they could lose 13.3 to 20.1% of their carbon stores.
- The results highlight the need to reduce global temperatures rapidly to maintain the healthy forests best able to sequester carbon from the atmosphere.
- The team reported their findings Feb. 6 in the journal Nature Climate Change.

Extreme heat takes a toll on tropical countries’ economies
- Extreme heat costs tropical countries more than 5% of their annual per capita GDP, new research shows, while more prosperous mid-latitude countries lose only about a 1% of GDP due to heat waves, which can even bolster economic growth in some instances.
- Poorer tropical countries suffer the worst effects of heat waves despite being least culpable and least economically capable of adapting.
- The effects of extreme heat and drought can hit hard in local communities, such as among Kenyan families who rely on cattle they can no longer feed.

Deadly landslides prompt Philippine president to call for tree planting
- Typhoon Nalgae, which made five landfalls on Oct. 29, killed 123 people across the Philippines, including at least 61 who died in floods and landslides on the southern island of Mindanao.
- After inspecting the damage wrought by the storm, President Ferdinand Marcos Jr. blamed deforestation and climate change for the scale of the disaster, and called on flood control plans to include tree planting.
- The Philippines already has an ambitious tree-planting program, but an audit found it has so far fallen short of its target.

Arctic sea ice loss to increase strong El Niño events linked to extreme weather: Study
- The frequency of strong El Niño events could increase by 35% by the end of the century as Arctic sea ice begins to melt out completely in the summer, according to a recent modeling study. El Niños — buildups of especially warm water in the eastern Pacific off of Peru — often trigger ‘devastating’ droughts, floods and cyclones around the globe.
- The findings provide more evidence that Arctic warming is affecting weather in other parts of the world — not only in the mid-latitudes, but as far away as the tropics.
- Other recent studies have found that sea ice loss is causing rapid acidification of the Arctic Ocean and more extreme precipitation and flooding in Svalbard, a Norwegian archipelago located between mainland Norway and the North Pole.

2022: Another consequential year for the melting Arctic
- Arctic sea ice extent shrank to its summertime minimum this week — tied with 2017 and 2018 for the 10th lowest ever recorded. However, the last 16 consecutive years have seen the least ice extent since the satellite record began. Polar sea ice extent, thickness and volume all continue trending steeply downward.
- Arctic air temperatures were high this summer, with parts of the region seeing unprecedented heating. Greenland saw air temperatures up to 36° F. above normal in September. Canada’s Northwest Territories saw record highs, hitting the 90s in July. Sea temperatures also remained very high in many parts of the Arctic Ocean.
- Scientists continue to be concerned as climate change warms the far North nearly four times faster than the rest of the planet, sparking concern over how polar warming may be impacting the atmospheric jet stream, intensifying disastrous extreme weather events worldwide, including heat waves, droughts and storms.
- While a mostly ice-free Arctic could occur as early as 2040, scientists emphasize that it needn’t happen. If humanity chooses to act now to drastically reduce greenhouse gas emissions, downward sea ice extent and volume trends could potentially be reversed.

Agulhas Current enigma: An oceanic gap in our climate understanding
- Comprehending the workings of western boundary ocean currents, like those of the Agulhas Current off the South African coast, may hold a key to Earth’s climate system. But understanding this particular current is hampered by a major lack of in-situ data. This gap leaves us in the dark about local, regional and global climate impacts.
- The Agulhas Current, located in the Indian Ocean, is one of the most energetic ocean current systems in the world. Changes to it can impact local weather in South Africa and elsewhere in the Southern Hemisphere, and perhaps influence large-scale climatic changes in the Northern Hemisphere and globally as well.
- However, it is not clear how and what these impacts may be, or when they may occur. With climate change escalating rapidly due to unabated human carbon emissions, it is now more important than ever that we understand the impacts of Southern Hemisphere ocean currents, and integrate their actions into climate models.
- But attempts at long-term monitoring of the Agulhas Current System have not been fully successful. Accomplishments and failures to date have underscored significant local research capacity challenges, and differences in the approach to, and financing of, ocean science in the Global North as compared to the Global South.

How close is the Amazon tipping point? Forest loss in the east changes the equation
- Scientists warn that the Amazon is approaching a tipping point beyond which it would begin to transition from a lush tropical forest into a dry, degraded savanna. This point may be reached when 25% of the forest is lost.
- In a newly released report, the Monitoring of the Andean Amazon Project (MAAP) estimates that 13.2% of the original Amazon forest biome has been lost due to deforestation and other causes.
- However, when the map is divided into thirds, it shows that 31% of the eastern Amazon has been lost. Moisture cycles through the forest from east to west, creating up to half of all rainfall across the Amazon. The 31% figure is critical, the report says, “because the tipping point will likely be triggered in the east.”
- Experts say the upcoming elections in Brazil could have dramatic consequences for the Amazon, and to avert the tipping point we must lower emissions, undertake ambitious reforestation projects, and build an economy based on the standing forest. Granting and honoring Indigenous land tenure and protected areas are also key strategies.

More droughts are coming, and the Amazon can’t keep up: Study
- Up to 50% of rainfall in the Amazon comes from the forest itself, as moisture is recycled from the trees to the atmosphere.
- In severe droughts, when the forest loses more water to evaporation than it receives from rain, the trees begin to die. For every three trees that die due to drought in the Amazon rainforest, a fourth tree, even if not directly affected by drought, will also die, according to a new study.
- As trees are lost and the forest dries up, parts of the Amazon will rapidly approach a tipping point, where they will transition into a degraded savanna-like ecosystem with few to no trees.
- The southern and southeastern Amazon are the most vulnerable regions to tipping. Here, deforestation and fires are at their most extreme, driven largely by cattle ranching and soy farming.

For lightning-prone communities in Bangladesh, new warning system may not be enough
- An average of four people a week are killed by lightning in Bangladesh, and the problem is expected to get worse as climate change increases the frequency of lightning strikes.
- Most of the victims tend to be farmers and fishers, who, like members of other poor communities around the world, are bearing the brunt of climate change impacts.
- The Bangladesh Meteorological Department has rolled out an early-warning system, based on modeling developed in collaboration with NASA, that it says will provide up to 54 hours’ warning of potential lightning strikes.
- But experts say the communities most in need of these alerts are those who don’t have access to the technology, and have called for other measures, such as building lightning arresters in open fields and wetlands, to protect vulnerable communities.

Bad weather knocks down Brazil’s grain production as ‘exhaustively forewarned’
- Brazil’s agricultural GDP declined by 8% in the first quarter of 2022 due to a severe drought in the country’s south caused by a rare triple-dip La Niña.
- In Rio Grande do Sul, the nation’s southernmost state, 56% of last year’s total soy harvest was lost, harming thousands of farmers.
- Scientists warn that climate change will make Brazil’s southern region, an agribusiness stronghold, widespread crop losses more common.
- Despite warnings, climate denial in the agriculture sector is getting in the way of mitigation efforts as the government of President Jair Bolsonaro and the agribusiness lobby push an anti-environmental agenda.

As stronger storms hit Bangladesh farmers, banks are climate collateral damage
- Farmers in coastal areas of Bangladesh are increasingly defaulting on their loans due to climate change-driven storms that are destroying the farms they put up as collateral.
- Agricultural loans for the year to May 2022 amounted to the equivalent of $3 billion, or a fifth of the value of all loans distributed in Bangladesh.
- Increasingly frequent and severe storms therefore pose as much of a threat to the country’s financial sector as to farming communities and the environment.
- The warming of the sea in the Bay of Bengal as a result of climate change is supercharging storms, giving them more energy, helping them to drive tidal surges farther inland and dump larger volumes of rain than before.

‘The volume of water is beyond control’: Q&A with flood expert M. Monirul Qader Mirza
- An early start to the monsoon and unusually heavy rains have caused massive flooding in northeastern Bangladesh, leaving millions of people stranded in floodwaters.
- The Meghna River Basin is accustomed to these flash floods, but the scale of the disaster this year has been compounded by human encroachment and development in the watershed region, said M. Monirul Qader Mirza, a water management expert.
- In an interview with Mongabay, Mirza emphasized the need for infrastructure planning to consider river and rainfall dynamics to mitigate flood risk, and to have an early-warning system in place to minimize damage.
- Mirza also said that identifying the role of climate change in the problem is complex and requires extensive studies and modeling, but added it’s indisputable that rainfall patterns have become increasingly erratic.

High tech early warning system could curb next South African locust swarms
- The worst locust swarms in South Africa’s Eastern Cape province in 25 years (occurring in May 2022) is in the past. But the millions of eggs laid by the insects could hatch this September, the beginning of spring in the Southern Hemisphere.
- Grassy farmland in the vast region was only just beginning to recover from a devastating six year drought which struck between 2015 – 2021, when the locust swarms arrived earlier this year.
- Farmers are now pinning their hopes on new software that will track newborn locusts in real time, enabling them to target and exterminate the insect pests before they take to the skies and reproduce.
- The software has been used in seven countries in the Horn of Africa and East Africa and is seen as a vital part of minimizing the size of swarms, which can become an annual disaster if they aren’t targeted immediately after birth. South Africa favors chemical pesticides over non-toxic biopesticides for locust control.

Beyond boundaries: Earth’s water cycle is being bent to breaking point
- The hydrological cycle is a fundamental natural process for keeping Earth’s operating system intact. Humanity and civilization are intimately dependent on the water cycle, but we have manipulated it vastly and destructively, to suit our needs.
- We don’t yet know the full global implications of human modifications to the water cycle. We do know such changes could lead to huge shifts in Earth systems, threatening life as it exists. Researchers are asking where and how they can measure change to determine if the water cycle is being pushed to the breaking point.
- Recent research has indicated that modifications to aspects of the water cycle are now causing Earth system destabilization at a scale that modern civilization might not have ever faced. That is already playing out in extreme weather events and long-term slow-onset climate alterations, with repercussions we don’t yet understand.
- There are no easy or simple solutions. To increase our chances of remaining in a “safe living space,” we need to reverse damage to the global hydrological cycle with large-scale interventions, including reductions in water use, and reversals of deforestation, land degradation, soil erosion, air pollution and climate change.

Even Antarctic snow can’t escape the plastic peril, study shows
- A study presents new evidence that microplastics are present in snow in Antarctica, one of the remotest places on Earth.
- Researchers collected snow samples at 19 sites across the Ross Ice Shelf in Antarctica, and found 29 microplastic particles per liter of melted snow — a higher amount than what was found in marine samples in Antarctica.
- The microplastics found in samples close to research stations were three times higher than what was found at other locations, prompting researchers to conclude that much of the plastic was coming from local clothing and equipment.

Bangladeshi coastal communities plant mangroves as a shield against cyclones
- Bangladesh’s southwestern coastal districts are prone to tidal surges, which can become extreme during cyclone seasons, with surges as high as 3 meters (10 feet).
- The coasts have embankments built across to keep the seeping seawater from reaching the coastal settlements, but as cyclones get more severe under a changing climate, these embankments aren’t enough, and losing houses to cyclonic floods has become the norm for coastal communities here.
- As a protection measure, the Bangladeshi government and several NGOs, with the communities’ participation, have initiated large-scale planting of mangrove trees along the embankments to act as a natural shield against tidal surges.
- The NGOs have provided the initial financial and technical support to the communities and are encouraging a self-reliant process of planting native mangrove species.

Cradle of transformation: The Mediterranean and climate change
- The Mediterranean region is warming 20% faster than the world as a whole, raising concerns about the impacts that climate change and other environmental upheaval will have on ecosystems, agriculture and the region’s 542 million people.
- Heat waves, drought, extreme weather and sea-level rise are among the impacts that the region can expect to see continue through the end of the century, and failing to stop emissions of carbon dioxide and other greenhouse gases could make these issues worse.
- Charting a course that both mitigates climate change and bolsters adaption to its effects is further complicated by the Mediterranean’s mix of countries, cultures and socioeconomics, leading to wide gaps in vulnerability in the region.

Beyond CO2, tropical forests a ‘cool’ solution to climate crisis, study finds
- Forests, increasingly looked to for their role in addressing climate change, can draw carbon from the atmosphere, but they also have more localized impacts on temperature and weather.
- Forests are responsible for about 0.5°C (0.9°F) of cooling globally when their ability to sequester carbon and these biophysical effects are considered, a recent study has found.
- Tropical forests, with their speedy uptake of carbon and the local cooling they provide — by humidifying the air, for example — are considered a “double win” for the climate.

Tropical trees’ growth and CO2 intake hit by more extreme dry seasons
- A new study has found that dry seasons that are warmer and drier than usual can stunt the growth of tropical trees, causing them to take in less carbon dioxide.
- While trees tend to grow more during the wet season, the researchers found that the dry season actually had a stronger impact on tree growth than the wet season.
- As climate change continues to raise temperatures, tropical trees could face increased risk of mortality and the possibility of becoming a net source of carbon, rather than a carbon sink.

Indonesia’s Riau province declares state of emergency ahead of fire season
- Almost every year vast swaths of Southeast Asia are covered in toxic haze, which causes air quality to reach hazardous levels and creates major health, environmental and economic problems.
- Recorded since the early ’70s, the smoke is almost entirely a result of large forest and peatland fires in Indonesia that are often illegally started to clear land for oil palm plantations.
- The governor of Indonesia’s Riau province in Sumatra, which, along with Borneo, is a primary location of the fires, has declared an emergency alert status to increase and expedite prevention and extinguishing efforts ahead of this year’s fire season.
- A national environmental NGO says the alert status shows the government has again failed to prevent the fires, and that the existing mitigation efforts fail to tackle the root of the problem.

Multiyear ice thinner than thought as Arctic sea ice reaches winter max: Studies
- Arctic sea ice has reached its yearly maximum extent at 14.88 million sq. km., the 10th lowest on record. The up-and-down story of sea ice extent in the past year highlights how unpredictable it can be from season to season, even as the overall decline continues.
- A study employing new satellite data found that Arctic multiyear sea ice — ice that survives the summer melt — is thinning even faster than previously thought and has lost a third of its volume in just two decades.
- This comes as Antarctic sea ice extent hit a record summer low, raising questions whether it is beginning a long-term decline, although experts are wary of drawing conclusions yet.
- While summer Arctic sea ice is predicted to mostly disappear by 2050, a new study suggests we could likely preserve it through 2100 by aggressively cutting methane emissions by 2030, along with reaching net-zero CO2 emissions by 2050.

‘Everything is on fire’: Flames rip through Iberá National Park in Argentina
- Fires in the central Corrientes province of northeast Argentina have burned through nearly 60% of Iberá National Park, home to protected marshlands, grasslands and forests that hosts an array of species.
- Many of the fires originated from nearby cattle ranches, and spread across significant portions of the park due to a prolonged drought.
- Conservationists are working to relocate a number of reintroduced species, including giant river otters and macaws, to places of safety.
- While experts say they expect a substantial loss to biodiversity, they add that the park should mount a rapid recovery thanks to all the rewilding work already done.

In trio of storms hitting Western Europe, role of climate change is complicated
- In early February, a polar vortex caused a series of three storms — Dudley, Eunice and Franklin — to hit the U.K. and Western Europe, unleashing heavy rains and winds across the region.
- The most powerful storm was Eunice, which had wind measurements of up to 196 kilometers per hour (122 miles per hour).
- Storms striking in quick succession are not unusual for Western Europe.
- While climate change did not necessarily drive these winter storms, it likely made the rainfall and storm surge more intense.

Two storms in two weeks carve trail of death and destruction in Madagascar
- Batsirai, a category 4 cyclone, struck Madagascar’s eastern coast on Feb. 5, leaving 10 people dead.
- The island nation is still recovering from another tropical storm, Ana, which made landfall on Jan. 22 and left dozens dead and hundreds of thousands homeless.
- Data from the U.S. National Oceanic and Atmospheric Administration show that 12 storms of category 4 or 5, the highest level, made landfall on Madagascar between 1911; of these 12, eight occurred since 2000.

In Africa, temperatures rise, but adaptation lags on West’s funding failure
- Last year was the third-warmest year for the continent, tied with 2019, with warming more pronounced here than the global average.
- The annual temperature in 2021 was 1.33°C (2.39°F) above average for the continent, with West and North Africa seeing an unusually warm year.
- Extreme events and long-drawn catastrophes are taking a toll and sapping resilience, while adaptation efforts are failing due to planning gaps and financing woes.
- Committed finance for adaptation is pegged at $2.7 billion to $5.3 billion annually, but the estimated cost of coping with climate impacts is almost double that.

In Indonesia’s Sulawesi, a community works to defuse blast-fishing crisis
- Decades of blast fishing have destroyed much of the coral reefs off Indonesia’s Lora village, reducing fish catches.
- Increased law enforcement and advocacy by NGOs has helped roll back these destructive practices, but other threats loom, including increasingly unpredictable weather and competition from large trawlers.
- A community organization is seeking to have the region zoned as a conservation area.

Sinkholes emerge in rural Kenya after series of floods, droughts
- In recent years, a number of sinkholes have emerged in Baringo county, a geologically active region in western Kenya’s Great Rift Valley.
- According to geologists, their appearance can be linked both to the worsening impacts of climate change through floods and droughts, and local communities drilling boreholes along precarious fault lines to access more water.
- According to members of the community, the sinkholes have yet to spur the county or the government into action, with food aid currently provided by local human rights organizations.
- Increases in floods are driving human-wildlife conflict for space, and pastoralists are having difficulty adapting to environmental changes.

With La Niña conditions back, is it good news for tropical forests?
- La Niña conditions have developed across the Pacific Ocean for the second year in a row, according to forecasters at NOAA’s Climate Prediction Center.
- A phase of the El Niño Southern Oscillation ocean-atmosphere cycle, La Niña heralds broadly cooler and wetter conditions across the tropics, with above-average rainfall predicted for important tropical rainforests in Southeast Asia and South America.
- Although the current conditions emerge toward the end of the fire season in the Amazon and Indonesia, experts say these biomes will benefit from wet conditions conducive to forest and peatland growth and recovery.
- Studies indicate that climate change will increase the frequency and severity of La Niña and El Niño events, which will occur against the backdrop of a warmer world, with inevitable implications for natural ecosystems and livelihoods.

Researchers express alarm as Arctic multiyear sea ice hits record low
- Low sea ice concentration can create a misleading picture of sea ice health in the Arctic. Though extent is only at its 10th lowest since satellite records began in 1979, the waters north of Alaska this September are full of diffuse ice.
- Of great concern to scientists, the Arctic has lost 95% of its thick multiyear sea ice since 1985. Older, thicker ice acts as a buffer against future Blue Ocean Events, expected as early as 2035. A BOE would mark a year when most Arctic ice melts out in summer.
- It no longer takes a freak-weather year to reach near record-lows for extent or volume. 2020 saw a second-place finish in the record book, behind 2012.

Reforestation holds promise for Europe’s increasingly drier summers
- A new study in Nature Geoscience suggests that if all land suitable for reforestation was forested in Europe, average summer rainfall would increase by 7.6%, partially ameliorating drier summers predicted as a result of climate change.
- While the study is based on all the potentially reforestable land in Europe after accounting for food security and biodiversity, the amount of land people are willing and able to reforest is likely to be lower in practice.
- As a statistical model, the study helps scientists and policymakers understand the relationship between forests and precipitation and highlight the benefits beyond carbon sequestration.

Humans’ role in climate warming ‘unequivocal,’ IPCC report shows
- The greenhouse gases humans have released into the atmosphere over the past 100 to 150 years has led to a 1.1°C (2°F) rise in global temperatures, according to the Intergovernmental Panel on Climate Change, or IPCC.
- The authors of the IPCC’s latest report use the strongest language yet to connect human activity to climate change, calling the link “unequivocal.”
- The report draws on the findings of thousands of studies, pointing to the need to cut CO2 emissions immediately while also suggesting that many of the impacts of climate change are irreversible.
- This report focuses on the science behind climate change and will be combined with two subsequent reports on the adaptation and vulnerability to the impacts of climate change and ways to mitigate its effects to produce the IPCC’s sixth assessment, scheduled for publication in September 2022.

Record heat waves are a taste of what’s to come under a changing climate
- A new study suggests that record-shattering heat events will become more frequent and more intense as the world continues to warm due to human-induced climate change.
- In a high-emissions scenario, the study suggests extreme heat waves will be two to seven times more probable between 2021 and 2050, and 21 times more probable between 2051 and 2080.
- If emissions can be curbed, however, and global temperatures do not exceed 2°C (3.6°F) above pre-industrial levels, this would help reduce extreme heat events.

Lessons from the 2021 Amazon flood (commentary)
- In June 2021, the annual flood season in the western and central Amazon reached record levels, and dramatic scenes of inundated homes, crops and city streets captured attention beyond Amazonia. This event provides lessons that must be learned.
- The high flood waters are explained by climatological forces that are expected to strengthen with projected global warming. Damaging floods represent just one of the predicted impacts in Amazônia under a warming climate.
- The administration of Brazilian President Jair Bolsonaro must change its current denialist positions on global warming and its policies that encourage deforestation. The Amazon forest must be maintained for many reasons in addition to its role in avoiding climate change.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Indonesia eyes less severe fire season, but COVID-19 could turn it deadly
- This year’s forest fire season in Indonesia is expected to be less severe than in previous years, but the haze from the burning could still compound the coronavirus crisis in the country.
- Favorable weather conditions and ongoing efforts to restore peatlands point to a “relatively benign” fire season, and hence less risk of severe haze, a new report says.
- Even before the pandemic, haze from forest and peat fires was known to increase cases of respiratory infections fourfold in the hardest-hit areas; combined with COVID-19, haze this time around could stretch the country’s overwhelmed hospitals beyond breaking point.
- Indonesia has recently become the global epicenter of the disease, registering more daily cases than India and Brazil, with the country’s doctors’ association warning the health care system has “functionally collapsed.”

As Arctic warms, scientists wrestle with its climate ‘tipping point’
- A leaked version of the newest science report from the U.N. Intergovernmental Panel on Climate Change warns of looming, potentially catastrophic tipping points for Arctic sea ice melt, tundra thaw, savannification of the Amazon rainforest, and other planetary environmental thresholds beyond which recovery may be impossible.
- But what are tipping points, and how does one pinpoint what causes them, or when they will occur? When studying a vast region, like the Arctic, answering these questions becomes dauntingly difficult, as complex positive feedback loops (amplifying climate warming impacts) and negative feedback loops (retarding them) collide with each other.
- In the Arctic, one working definition of a climatic tipping point is when nearly all sea ice disappears in summer, causing a Blue Ocean Event. But attempts to model when a Blue Ocean Event will occur have run up against chaotic and complex feedback loop interactions.
- Among these are behaviors of ocean currents, winds, waves, clouds, snow cover, sea ice shape, permafrost melt, subarctic wildfires, aerosols and more, with many interactions still poorly understood. Some scientists say too much focus is going to tipping points, and research should be going to the “radical uncertainty” of escalating extreme local events.

As Arctic melt sets early July record, hard times lie ahead for ice: Studies
- Arctic sea ice fell to its lowest extent on record for this time of year on July 5, even though the spring had so far been relatively cool and stormy — conditions that, in the past, would have protected the ice.
- Three new studies help explain why. One found that increasing air temperatures and intrusion of warm water from the North Atlantic into the Barents and Kara Seas — a climate change-driven process known as Atlantification — are overpowering the ice’s ability to regrow in winter.
- Another study found that sea ice in coastal areas may be thinning at up to twice the pace previously thought. In three coastal seas — Laptev, Kara, and Chukchi — the rate of coastal ice decline increased by 70%, 98%, and 110% respectively when compared to earlier models.
- A third study found accelerated sea ice loss in the Wandel Sea, pointing to a possible assault by global warming on the Arctic’s Last Ice Area — a last bastion of multi-year sea ice which stretches from Greenland along the Canadian Arctic Archipelago. Combined, this research shows Arctic ice may be in worse trouble than thought.

Arctic biodiversity at risk as world overshoots climate planetary boundary
- The Arctic Ocean biome is changing rapidly, warming at twice the rate of the rest of the world. In turn, multiyear sea ice is thinning and shrinking, upsetting the system’s natural equilibrium.
- Thinner sea ice has led to massive under-ice phytoplankton blooms, drawing southern species poleward; fish species from lower latitudes are moving into the peripheral seas of the Arctic Ocean, displacing and outcompeting native Arctic species.
- Predators at the top of the food chain, such as polar bears, are suffering the consequences of disappearing ice, forced onto land for longer periods of time where they cannot productively hunt.
- The Central Arctic Ocean Fisheries Agreement has been signed by 10 parties to prevent unregulated commercial fishing in the basin until the region and climate change impacts are better understood by scientists. International cooperation will be critical to protect what biodiversity remains.

As Arctic sea ice hits annual maximum, concern grows over polar ice loss: Studies
- Arctic sea ice reaches its annual maximum extent in March. But while ice extent is high this year, scientists are far more concerned by the drastic loss of sea ice volume, which continues its steady decline.
- A new study has documented drastic ice loss in both the north and south polar regions; scientists found that the single biggest reduction came from Arctic sea ice — the Earth lost 7.6 trillion metric tons of it in the last three decades.
- Another new study shows that the last bastion of old, thick multiyear ice in the Arctic, north of Greenland and Ellesmere Island, is diminishing as the stability of the Nares ice arches declines — blockages which work like a cork in a bottle to stop multiyear ice from flowing out into the Atlantic.
- Meanwhile, researchers warn about the urgent need for new Arctic monitoring satellites. Currently there is just one in operation, the DMSP-F18 satellite, and it has already been in orbit more than a decade. Its failure could leave researchers blind and disrupt an Arctic ice database continuous back to 1978.

Dusty winds exacerbate looming famine in Madagascar’s deep south
- At least 1.27 million people need humanitarian assistance in Madagascar’s drought-hit deep south, according to a Jan. 18 request by the U.N. and the Malagasy government for $75.9 million in international aid to cope with the crisis.
- The area is also experiencing dust and sand storms, a natural phenomenon known as a tiomena that is exacerbating the crisis by smothering crops, forests, buildings and roads.
- Tiomenas may be increasingly common as southern Madagascar undergoes a long-term drying trend.
- Experts say upgrading the area’s water supply system is an urgent priority and recommend massive tree planting to provide wind breaks, protect soils from erosion and create more humidity.

Top 10 environmental news stories of 2020
- 2020 is a year that many people would like to forget. Here’s a look at 10 of the biggest environmental storylines to remember.
- The impact of the COVID-19 pandemic transcended virtually everything in 2020, including the environment, from canceled summits on climate and biodiversity to a temporary dip in air pollution and greenhouse gas emissions, to greater awareness of the link between human health and planetary health.
- Conservation efforts in tropical countries were especially hard hit by the pandemic.

One year on: Insects still in peril as world struggles with global pandemic
- In June 2019, in response to media outcry and alarm over a supposed ongoing global “Insect Apocalypse,” Mongabay published a thorough four-part survey on the state of the world’s insect species and their populations.
- In four, in-depth stories, science writer Jeremy Hance interviewed 24 leading entomologists and other scientists on six continents and working in 12 nations to get their expert views on the rate of insect decline in Europe, the U.S., and especially the tropics, including Latin America, Africa, and Australia.
- Now, 16 months later, Hance reaches out to seven of those scientists to see what’s new. He finds much bad news: butterflies in Ohio declining by 2% per year, 94% of wild bee interactions with native plants lost in New England, and grasshopper abundance falling by 30% in a protected Kansas grassland over 20 years.
- Scientists say such losses aren’t surprising; what’s alarming is our inaction. One researcher concludes: “Real insect conservation would mean conserving large whole ecosystems both from the point source attacks, AND the overall blanket of climate change and six billion more people on the planet than there should be.”

Brave New Arctic: Sea ice has yet to form off of Siberia, worrying scientists
- After a summer that saw record Siberian fires and polar temperatures topping 100 degrees Fahrenheit, along with near record low sea ice extent in September, the Arctic Ocean’s refreeze has slowed to a crawl.
- The Laptev Sea and East Siberian Sea are, at this point, failing to re-freeze as rapidly as in the past. Scientists see all of these worrying events, along with many other indicators including fast melting permafrost, as harbingers of a northern polar region that may be entering a new climate regime.
- Models predict the Arctic will be ice-free in summer by 2040 or 2050, with unforeseen negative impacts not only in the Far North, but on people, economies and ecosystems around the globe. One major concern: scientists worry how changes in the Arctic might alter temperate weather systems, impacting global food security.
- “We’re conducting this blind experiment, and we don’t yet know the real implications,” one sea ice researcher tells Mongabay. “How do you sell climate change to be as much of an emergency as COVID-19? Except that it will kill a lot more people.”

Arctic Sea ice melts to second-place finish at annual minimum
- At the annual September Arctic sea ice minimum this year, the ice extent was reduced to just 3.74 million square kilometers, a low that surpassed every year since 1979 except 2012, which saw a minimum of 3.41 million square kilometers.
- While 2012 was an anomaly (a year in which an immense August cyclone shattered the weakened ice), 2020 came very close to that record, but without any such storm, though the region did see intense July and August heat.
- A new study finds, once again, that what starts in the Arctic doesn’t stay there. Researchers say that Asia is seeing lengthier bouts of extreme storms, droughts, heat and cold as weather systems stall there, possibly due to a weakening Northern Hemisphere jet stream — an effect thought to be due to Arctic warming.
- In other new research, scientists say a layer of warm Atlantic water entering the Arctic, which had always stayed down deep in the past, is starting to rise toward, and mix with, colder surface waters. That mixing could be fatal to the Arctic sea ice in the future — with unknown, but potentially dire impacts on global climate stability.

Can we predict where Amazon fires will occur? And to what end?
- If it was possible to accurately forecast where Amazon fires were most likely to occur each year, it should theoretically be far easier to prevent and control those fires.
- Amazon fires are currently predicted in two ways: first, based on deforestation, much of it illegal, that occurs in the wet months before the annual fire season; it is these deforested areas that are most often set on fire in the dry months of July through September.
- Second, it’s also possible to predict the approximate severity and Amazon region in which fires may occur based on climate and drought forecasts for the biome, often based on ocean temperatures.
- But being able to predict where Amazon fires might occur is only a first step. A strong, proactive government response is also needed to prevent and control fires, and in order to apprehend and prosecute those who set them ablaze in the Amazon.

Traversing Russia’s remote taiga in pursuit of the Blakiston’s fish owl
- The Blakiston’s fish owl is the world’s largest owl, ranging from the eastern woodlands of Hokkaido, Japan, to the Primorye territory in the south of Russia’s Far East.
- The species is endangered, with only 1,500 to 3,700 fish owls remaining in the wild.
- In his new, just published book, Owls of the Eastern Ice, biologist Jonathan Slaght chronicles his experiences and misadventures as an American researcher in Siberia, while also revealing the fish owl’s fascinating secret world.
- To protect the fish owl, Slaght and his Russian colleagues advocate for limiting road access into high biodiversity areas in Siberia.

Photos show scale of massive fires tearing through Siberian forests
- A series of newly released images from Greenpeace International show megafires burning through the Krasnoyarsk region of Siberia, Russia.
- It’s estimated that fires have burnt more than 20.9 million hectares of land in Russia, and 10.9 million hectares of forest, since the start of 2020.
- The fires are being helped by unusually warm temperatures, including a reading of more than 38° Celsius (100° Fahrenheit) in the town of Verkhoyansk — the hottest on record inside the Arctic Circle.
- There are concerns that the smoke from the Siberian fires will cause respiratory problems for people living in urban areas, especially in the midst of the COVID-19 pandemic.

COVID-19 may worsen burning and haze as Indonesia enters dry season
- Reallocation of disaster preparedness funds for the COVID-19 pandemic could allow a flare-up of forest fires and haze as the dry season gets underway in Indonesia, with smog from Sumatra reported to have reached Southern Thailand.
- While the country is expected to see a milder dry season than last year, any haze episodes will exacerbate an already precarious public health situation as a result of the pandemic.
- Researchers in Singapore say Indonesian authorities are largely on the right track in preventing fires, which are typically set to clear land for plantations, but more needs to be done in terms of enforcement on the ground.
- They also suggest that small and medium plantation companies — rather than large companies or smallholder farmers — will have the most impact on how severe the fire and haze problem will be.

Crediting the lockdown for Sri Lanka’s cleaner air masks the real problem (Commentary)
- The lockdown on traffic and industry imposed by the Sri Lankan government in response to the COVID-19 pandemic coincided with a period of improved air quality, especially in Colombo.
- But the popular perception that the lockdown led to the im-provement ignores a much more important factor, says envi-ronmental scientist Lareef Zubair: a seasonal change in wind di-rection bringing clean, fresh air from the Indian Ocean.
- Air quality in Colombo continues to be influenced largely by transboundary transport of air pollution from the Indian sub-continent and Southeast Asia; forest, scrub and agricultural res-idue burning; poor solid waste management systems; and the Norochcholai coal power plant located in Sri Lanka’s northwest.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Aided by weather, Sri Lanka’s lockdown leads to decline in air, sea pollution
- Air pollution in Sri Lanka’s urban areas has decreased by up to 75% during the lockdown imposed in response to the COVID-19 pandemic, while plastic pollution and other forms of marine pollution have decreased by up to 40% along the island’s coastline, authorities say.
- Experts say meteorological conditions are also a factor, including the monsoonal change in wind direction and lack of rainfall in recent months.
- But the environmental respite is likely to be temporary, while the lockdown period threatens to see a surge in another type of waste — face masks — washing out to sea and on beaches if no proper waste management mechanisms are introduced.
- Experts say the tangible improvements in environmental indicators give a glimpse of how effective lifestyle and economic changes can lead to lasting pollution reduction in Sri Lanka.

Philippines bids farewell to satellite that launched enviro policy into the space age
- Diwata-1, the Philippines’ first microsatellite, has ended its four years in Earth orbit, burning up in the atmosphere on April 6.
- The microsatellite captured more than 17,000 images of the Philippines, covering 38% of the country’s land area.
- Diwata-1 ushered in an age of Earth satellite observation in the Philippines, contributing to science-based approaches to planning, conservation, risk management, and mapping.
- Scientists involved in the program say they hope that analyses and reports culled from the country’s Earth observation technology can help in policymaking and decision-making.

World is fast losing its cool: Polar regions in deep trouble, say scientists
- As representatives of the world’s nations gather in Madrid at COP 25 this week to discuss global warming policy, a comprehensive new report shows how climate change is disproportionately affecting the Arctic and Antarctic — the Arctic especially is warming tremendously faster than the rest of the world.
- If the planet sees a rise in average temperatures of 2 degrees Celsius, the polar regions will be the hardest hit ecosystems on earth, according to researchers, bringing drastic changes to the region. By the time the lower latitudes hit that mark, it’s projected the Arctic will see temperature increases of 4 degrees Celsius.
- In fact, polar regions are already seeing quickening sea ice melt, permafrost thaws, record wildfires, ice shelves calving, and impacts on cold-adapted species — ranging from Arctic polar bears to Antarctic penguins. What starts in cold areas doesn’t stay there: sea level rise and temperate extreme weather are both linked to polar events.
- The only way out of the trends escalating toward a climate catastrophe at the poles, say scientists, is for nations to begin aggressively reducing greenhouse gas emissions now and embracing sustainable green energy technologies and policies. It remains to be seen whether the negotiators at COP 25 will embrace such solutions.

Typhoon-prone Philippines gets climate funding for early warning system
- The Philippines has secured $10 million in funding from the U.N.’s Green Climate Fund, its first under a scheme to provide financial assistance for adaptation and mitigation in countries vulnerable to climate change impacts.
- The funding will go toward establishing a multi-hazard and impact-based forecasting and early warning system in four pilot areas in the country to assist local government units in implementing appropriate early responses to hazard alerts.
- The Philippines is one of the countries most vulnerable to the impacts of climate change, which include increasingly more intense storms slamming into the country from the warming Pacific.

The climate crisis and the pain of losing what we love (commentary)
- World leaders came to the UN last week to decisively tackle climate change again. “This is not a negotiation summit because we don’t negotiate with nature. This is a Climate Action Summit!” declared the UN Secretary-General. But again, global leaders failed and committed to carbon cuts that fall far short of curbing catastrophe.
- In doing so, our leaders committed us to an escalating global environmental crisis that is already unleashing vast changes across Earth’s ecosystems — with many sweeping alterations charted by our scientists, but many other local shifts and absences only noted by those who observe and cherish wild things.
- The loss of familiar weather patterns, plants and animals (from monarchs to native bees) and an invasion of opportunistic living things (Japanese knotweed to Asian longhorned ticks) can foster feelings of vertigo — of being a stranger in a strange land — emotions, so personal and rubbing so raw, they can be hard to describe.
- So I’ve tried to express my own feelings for one place, Vermont, my home, that is today seeing rapid change. At the end of this piece, Mongabay invites you to tally your own natural losses. We’ll share your responses in a later story. This post is a commentary. Views expressed are those of the author, not necessarily Mongabay.

Mongabay investigative series helps confirm global insect decline
- In a newly published four-part series, Mongabay takes a deep dive into the science behind the so-called “Insect Apocalypse,” recently reported in the mainstream media.
- To create the series, Mongabay interviewed 24 entomologists and other scientists on six continents and working in 12 nations, producing what is possibly the most in-depth reporting published to date by any news media outlet on the looming insect abundance crisis.
- While major peer-reviewed studies are few (with evidence resting primarily so far on findings in Germany and Puerto Rico), there is near consensus among the two dozen researchers surveyed: Insects are likely in serious global decline.
- The series is in four parts: an introduction and critical review of existing peer-reviewed data; a look at temperate insect declines; a survey of tropical declines; and solutions to the problem. Researchers agree: Conserving insects — imperative to preserving the world’s ecosystem services — is vital to humanity.

As Cambodia swelters, climate-change suspicion falls on deforestation
- Cambodia has one of the highest rates of deforestation in the world, with key drivers including demand for timber products, land-use conversion, and urbanization.
- Extreme temperatures have led to public criticism linking deforestation to unusually hot weather.
- The Cambodian government has denied this connection, but emerging science provides compelling links between the two issues.

The Great Insect Dying: How to save insects and ourselves
- The entomologists interviewed for this Mongabay series agreed on three major causes for the ongoing and escalating collapse of global insect populations: habitat loss (especially due to agribusiness expansion), climate change and pesticide use. Some added a fourth cause: human overpopulation.
- Solutions to these problems exist, most agreed, but political commitment, major institutional funding and a large-scale vision are lacking. To combat habitat loss, researchers urge preservation of biodiversity hotspots such as primary rainforest, regeneration of damaged ecosystems, and nature-friendly agriculture.
- Combatting climate change, scientists agree, requires deep carbon emission cuts along with the establishment of secure, very large conserved areas and corridors encompassing a wide variety of temperate and tropical ecosystems, sometimes designed with preserving specific insect populations in mind.
- Pesticide use solutions include bans of some toxins and pesticide seed coatings, the education of farmers by scientists rather than by pesticide companies, and importantly, a rethinking of agribusiness practices. The Netherlands’ Delta Plan for Biodiversity Recovery includes some of these elements.

The Great Insect Dying: The tropics in trouble and some hope
- Insect species are most diverse in the tropics, but are largely unresearched, with many species not described by science. But entomologists believe abundance is being impacted by climate change, habitat destruction and the introduction of industrial agribusiness with its heavy pesticide use.
- A 2018 repeat of a 1976 study in Puerto Rico, which measured the total biomass of a rainforest’s arthropods, found that in the intervening decades populations collapsed. Sticky traps caught up to 60-fold fewer insects than 37 years prior, while ground netting caught 8 times fewer insects than in 1976.
- The same researchers also looked at insect abundance in a tropical forest in Western Mexico. There, biomass abundance fell eightfold in sticky traps from 1981 to 2014. Researchers from Southeast Asia, Australia, Oceania and Africa all expressed concern to Mongabay over possible insect abundance declines.
- In response to feared tropical declines, new insect surveys are being launched, including the Arthropod Initiative and Global Malaise Trap Program. But all of these new initiatives suffer the same dire problem: a dearth of funding and lack of interest from foundations, conservation groups and governments.

The Great Insect Dying: Vanishing act in Europe and North America
- Though arthropods make up most of the species on Earth, and much of the planet’s biomass, they are significantly understudied compared to mammals, plants, birds, amphibians, reptiles and fish. Lack of baseline data makes insect abundance decline difficult to assess.
- Insects in the temperate EU and U.S. are the world’s best studied, so it is here that scientists expect to detect precipitous declines first. A groundbreaking study published in October 2017 found that flying insects in 63 protected areas in Germany had declined by 75 percent in just 25 years.
- The UK Butterfly Monitoring Scheme has a 43-year butterfly record, and over that time two-thirds of the nations’ species have decreased. Another recent paper found an 84 percent decline in butterflies in the Netherlands from 1890 to 2017. Still, EU researchers say far more data points are needed.
- Neither the U.S. or Canada have conducted an in-depth study similar to that in Germany. But entomologists agree that major abundance declines are likely underway, and many are planning studies to detect population drops. Contributors to decline are climate change, pesticides and ecosystem destruction.

The Great Insect Dying: A global look at a deepening crisis
- Recent studies from Germany and Puerto Rico, and a global meta-study, all point to a serious, dramatic decline in insect abundance. Plummeting insect populations could deeply impact ecosystems and human civilization, as these tiny creatures form the base of the food chain, pollinate, dispose of waste, and enliven soils.
- However, limited baseline data makes it difficult for scientists to say with certainty just how deep the crisis may be, though anecdotal evidence is strong. To that end, Mongabay is launching a four-part series — likely the most in-depth, nuanced look at insect decline yet published by any media outlet.
- Mongabay interviewed 24 entomologists and researchers on six continents working in over a dozen nations to determine what we know regarding the “great insect dying,” including an overview article, and an in-depth story looking at temperate insects in the U.S. and the European Union — the best studied for their abundance.
- We also utilize Mongabay’s position as a leader in tropical reporting to focus solely on insect declines in the tropics and subtropics, where lack of baseline data is causing scientists to rush to create new, urgently needed survey study projects. The final story looks at what we can do to curb and reverse the loss of insect abundance.

Study finds people apt to shrug off extreme weather as normal
- A new study published Feb. 25 that tracked Twitter posts on weather-related topics has found that people are quick to accept unusual weather as normal.
- The researchers calculated that we humans set our baseline for what we consider normal weather from what we’ve experienced in just the past two to eight years.
- The authors of the study write that, as people get used to wilder swings in temperature and other weather patterns, they might be reticent to find ways to deal with climate change or even see it as a problem.

Warmer waters shrink krill habitat around Antarctica
- A new study has found that fewer young krill are surviving to adulthood around Antarctica as ocean temperatures have risen in the Southern Ocean in the past few decades.
- The researchers, who looked at decades of data on krill body lengths and abundance, found that the highest densities of krill had shifted southward by some 440 kilometers (273 miles) since the 1920s.
- The scientists note that the findings could alter food webs in the Southern Ocean.
- Currently, the internationally managed krill fishery does not take the location and size of the krill population into account.

Cyclone harmed Fijian crab fishery in 2016, research finds
- Research published in the journal Climate and Development demonstrates that Tropical Cyclone Winston damaged mud-crab fisheries in Fiji in 2016.
- Surveys of the mostly women crab fishers in Bua province before and after Winston, one of the strongest storms ever recorded in the Southern Hemisphere, revealed that mud crabs were smaller and less numerous following the cyclone.
- The research could help government agencies address the lingering impacts of natural disasters to community fisheries.

Research links specific 2017 extreme weather events to climate change
- According to the seventh annual special report by the Bulletin of the American Meteorological Society (BAMS) probing the causal links between rising global temperatures and extreme weather events, issued last month, climate change made the Northern Great Plains drought of 2017 some 1.5 times more likely and greatly enhanced its intensity by driving long-term reductions in soil moisture.
- For the second year in a row, scientists were able to identify specific extreme weather events that cannot be explained without factoring in Earth’s warming global climate.
- A team of 120 scientists from 10 different countries used historical observations and model simulations to produce the 17 peer-reviewed analyses collected in the BAMS special report examining extraordinary weather events from around the globe that were made more likely or exacerbated by anthropogenic (human-caused) climate change.

High sea levels thousands of years ago aided island formation
- A recent study has found that high sea levels were critical to the formation of coral reef islands in the Indian Ocean thousands of years ago.
- The findings suggest that rising sea levels driven by climate change might not destroy all coral reef islands.
- However, the authors caution that the same higher-energy waves that help build these islands could also destroy the infrastructure on them that humans depend on.
- They also say that, for coral reef island formation to occur, the reef must be healthy to begin with — something that risks being negated by rising water acidity and temperature, both the result of climate change.

Global warming, human activities causing increased storm runoff, flash floods
- A new study published in the journal Nature Communications this week looks at how storm runoff levels might respond to future changes in surface temperature and atmospheric moisture content driven by both natural causes and human activities.
- The research team behind the study, led by Pierre Gentine, an associate professor of earth and environmental engineering at Columbia University in New York City, says that there’s is the first global analysis to show that storm runoff extremes are rising sharply in response to climate and human-induced changes — and that the magnitude of storm runoff is likely to continue increasing in most regions at rates substantially higher than projected by previous climate models.
- Gentile and team argue that there is “an urgent need” to increase human society’s resilience to both climate change and the changing environment, because storm runoff extremes are intensifying as the world warms and our existing infrastructure systems may not be able to cope.

Dress like a polar bear: learning to love muskoxen at 15 below zero
- Enduring subzero temperatures that make your face freeze, dressing as a bear, and getting chased by an angry male muskox, are all in a day’s work for biologist Joel Berger. His experiences and scientific insights are featured in a new book that focuses on the lives and survival strategies of muskoxen and other cold-adapted animals.
- The autobiographical book, “Extreme Conservation: Life at the Edge of the World,” profiles Berger’s studies of inhospitable ecosystems, ranging from the high latitudes above the Arctic Circle, to the Himalayas and Tibetan Plateau.
- Mongabay contributor Gloria Dickie interviews Berger to see what makes a human want to live and work in some of the Earth’s most brutal environments. The quick answer: to see how barely studied Northern and alpine large mammals — especially muskoxen — are adapting, or not adapting, to a rapidly warming world.
- Berger’s findings regarding instinctual and learned behavior, evolution and survival in a globally warmed world turn out to be revelatory not only to cold-adapted animals, but also relevant to wildlife species around the globe — and to the scientists who want to conserve them.

Common ground on the prairie (commentary)
- Good stewardship of our native grasslands is one of the best ways to survive the next weather event. Grasses are rooted in the ground, which enables the soil to absorb and retain more water. That, in turn, prevents sediment, fertilizer, pesticides, and other compounds in the soil from running off into nearby water ways. And by absorbing and storing more water, the land better withstands flood and drought alike.
- Healthy grasslands also serve as a check against climate change, pulling heat-trapping carbon dioxide out of the air and storing it in the soil. Research shows that improving grazing management practices on just one acre of grassland can pull an average of 419 extra pounds of carbon out of the atmosphere each year.
- This is an important message for the governors, mayors, CEOs and producers gathering in San Francisco for the Global Climate Action Summit (GCAS). There, they will demonstrate the progress the public and private sectors have made in reducing carbon emissions and they’ll set ambitious new goals. Land stewardship will be high on the agenda, as it should be.

Species evolve more than twice as fast at poles as in tropics: study
- Considering the swarming biodiversity at the equator, and the lack of diversity near the poles, scientists have long assumed that species evolve more rapidly in warm waters. But a new study of the evolutionary development of 30,000 fish species has turned that idea on its head.
- Biologists found that a fish species in the tropics split into a new species on average every 10 to 20 million years. But near the poles, that average rate is roughly every four million years – more than twice as fast.
- The reason may be the far more extreme and less stable climatic conditions found near the poles. This results in more frequent extinctions, which clears out species diversity and empties ecological niches, setting the stage for the next new burst of species formation in other groups of organisms.
- But if species form faster at the poles than in the tropics, why isn’t there greater biodiversity in the Arctic and Antarctic than at the equator? One possibility: while speciation is more rapid at the poles, extinctions may be more numerous too. But this still isn’t clear, and more research will be needed to find out.

Rwandan people and mountain gorillas face changing climate together
- The Critically Endangered mountain gorilla (Gorilla beringei beringei), has been brought back from extinction’s brink in Rwanda, with numbers in the Virunga Mountains around Volcanoes National Park estimated at 604 individuals in 2016, up from 480 in 2010. But long-time observers say climate change is bringing new survival challenges to the area.
- Longer and deeper droughts in recent years have caused serious water shortages, which impact both local farmers and the mountain gorillas. People now must often go deep into the park to find clean water, which increases the likelihood of contact with the great apes, which increases the likelihood for the transfer of human diseases to the animals.
- Hotter temps and dryer conditions could also pressure farmers to move into gorilla habitat in future, as they seek more productive cropland at higher altitudes. Also, as the climate changes, bamboo availability may be decreasing, depriving gorillas of a favorite food. This could force troops to forage outside the park in croplands, possibly leading to conflict.
- Forced changes in diet could impact gorilla nutrition, making the great apes more susceptible to disease. A major disease outbreak could be disastrous due to low population numbers. Scientists urge more research to understand how climate change affects human behavior, which then affects gorillas, and how the fate of the two primates intertwines.

Beyond polar bears: Arctic animals share in vulnerable climate future
- The media has long focused on the impacts of climate change on polar bears. But with Arctic temperatures rising fast (this winter saw the warmest October to February temperatures ever recorded), a wide range of Arctic fauna appears to be at risk, though more studies are needed to determine precise causes, current effects on population, and future projections.
- Diminishing Arctic snow, especially in the spring, may leave wolverines without ideal places to den. Caribou and reindeer populations have been in serious decline due to natural population fluctuation, but scientists don’t know if their numbers will recover under changed climate conditions.
- Lemmings are also being impacted by diminishing snow, often leaving the rodents without cover in spring and autumn. Their decline could impact the predators that prey on them, including Arctic foxes, red foxes, weasels, wolverines, and snowy and short-eared owls.
- Snowy owls have raised concerns because the seabirds they hunt in winter, which congregate around small holes in the Arctic ice, could become more widely dispersed in broader stretches of open water and therefore be harder to prey on. Scientists say more study of Arctic wildlife is urgently needed, but funding and media attention remains sparse.

Muskox and other Arctic mammals are feeling the heat of climate change
- Past studies have looked at Arctic climate change impacts on wildlife primarily among marine animals and with polar bears, but there is little data on most terrestrial mammals.
- Now, As part of a broader attempt to develop an ecological baseline for Arctic wildlife, researchers have focused on muskoxen, the least studied mammal in North America.
- According to a new study, increasingly common extreme weather events – such as rain-on-snow and extremely dry winter conditions occurring in Russia and Alaska during muskox gestation – result in smaller head size among muskox young. Smaller animals generally have poor survivorship rates.
- Scientists say that, with the Arctic warming twice as fast as the world average, new studies are urgently needed on cold climate mammals including muskoxen, reindeer and caribou, to determine how rapidly escalating climate change up North is impacting wildlife, habitats and ecosystems.

2017 was third-hottest year on record in U.S. and costliest in terms of extreme weather and climate disasters
- According to data released by the National Oceanic and Atmospheric Association yesterday, 2017 was the third-hottest year on record in the United States.
- Based on a preliminary analysis of the data, NOAA scientists determined that the average annual temperature for the 48 contiguous U.S. states was 54.6 degrees Fahrenheit last year, about 2.6 degrees Fahrenheit higher than the 20th century average.
- The country also experienced 16 weather and climate disasters that inflicted damages of $1 billion or more, which collectively cost a total of approximately $306 billion in losses – a new annual record for the U.S., NOAA reported.

Florida’s iguanas falling from trees in cold snap
- Green iguanas are not native to southern Florida, but typically do well in the region’s mild temperatures.
- During the recent cold snap, stunned iguanas have been losing their grip on their tree perches and falling to the ground, semi-frozen.
- Some sea animals are also showing signs of stress from the cold, including sea turtles and manatees.

As 2017 hurricane season ends, scientists assess tropical forest harm
- This year’s Atlantic hurricane season – one for the record books – ended on 30 November, seeing six Category 3 to 5 storms wreaking massive destruction across the Caribbean, in the U.S. and Mexico. While damage to the built environment is fairly easy to assess, harm to conserved areas and species is more difficult to determine.
- Satellite images show extensive damage to the 28,400-acre El Yunque National Forest in Puerto Rico, the United States’ only national tropical rainforest. However, observers on the ground say the forest is showing signs of a quick recovery.
- More serious is harm to already stressed, endangered species with small populations. El Yunque’s Critically Endangered Puerto Rican parrot was hard hit: out of 50 endemic wild parrots, 16 are known dead. Likewise, the Endangered imperial parrot endemic to Dominica, spotted just three times since Hurricane Maria.
- Ecosystems and species need time to recover between storms. If the intensity of hurricanes continues to increase due to escalating global warming as predicted, tropical ecosystem and species resilience may be seriously tested.

New study: Bird species blossom in stable climates
- A team of scientists from Sweden and the United States found that more bird species inhabit stable climates.
- The finding runs counter the hypothesis that a changing climate induces the evolution of species.
- That could mean that these bird species will be less adapted to upticks in temperature as part of current climate change.
- But the stability of these climates could also protect the species living there since they’re not expected to warm as much as more seasonal areas.

Murky future for freshwater fish in the Amazon floodplains
- An extreme drought in 2005 decreased many freshwater fish species abundance in areas like Lago Catalão, and many haven’t recovered yet.
- Drought overturned the ecology of the lake over time – big fish populations declined while little fish boomed.
- The shift has direct impacts on diets in the region since many local people depend on fish for protein, meaning that climate change is already influencing food reserves here.

Deforestation reducing monsoon rainfall in India: new study
- Large-scale deforestation in India has resulted in a decline in rainfall, especially in north and northeast India, a new study has found.
- Deforestation has resulted in a decline in evapotranspiration in these regions.
- Reduced evapotranspiration lowers “recycled precipitation”, which accounts for a quarter of the rainfall during late monsoon (August and September).

More than 300 reindeer killed by lightning in Norway
- The Hardangervidda lightning strike was unusually deadly, officials say.
- The mass death may have occurred because as herd animals, reindeer tend to huddle together during bad weather.
- Officials have sent a team of people to take samples from the bodies and send them to the Norwegian Veterinary Institute for research.

Millions of fish die suddenly in Indonesia’s giant Lake Toba
- Government researchers are analyzing samples from the lake and should have a prognosis soon.
- Hundreds of local volunteers have set about clearing the water of fish carcasses, which they fear will harm the ecosystem if left to fester for long.
- The die-off means huge losses for local farmers.

Nganyi: The tiny forest in Kenya that predicts the weather
- “Rainmakers” in the Bunyore community observe the flora and fauna in the Nganyi forest shrine to predict weather conditions. These predictions have proved as accurate as forecasts made through scientific equipment.
- Institutions throughout Kenya are protecting and learning from Nganyi forest, and a radio station has been established to broadcast its forecasts to the greater community.
- But global warming has shifted East Africa’s climate, drying out croplands and threatening the region’s little remaining forestland – including the Nganyi forest shrine.
