Environment & Climate Crises in 2026

Severe monsoon flooding and late-season tropical systems in late 2025 caused a multi-country disaster across Southeast and South Asia, with the heaviest impacts reported in Indonesia, Thailand, Malaysia, Sri Lanka, Vietnam, and the Philippines. Regional reporting in early December 2025 put the death toll at more than 1,100, while later cross-regional estimates rose to more than 1,300 fatalities and at least US$20 billion in losses, reflecting the scale of damage still being assessed. Country-level impacts remained extreme and unevenly updated by source: Indonesia reported the largest toll, with figures ranging from about 700 deaths to more than 800 deaths and hundreds of thousands displaced; Thailand reported more than 180 deaths in some early December reporting and multi-billion-baht damage; Sri Lanka reported more than 330 deaths in one assessment and over 450 in another later estimate; Vietnam reported 98 deaths and about US$3.2 billion in storm-related losses; and Malaysia reported fatalities in the low single digits but tens of thousands displaced at the peak. The crisis damaged homes, schools, roads, bridges, rail lines, crops, and power infrastructure, and many affected communities remained without electricity, safe drinking water, or adequate healthcare after the peak floods.

Arctic permafrost thaw remains a fast-growing climate and infrastructure crisis, driven by warming in the Arctic that is far above the global average and by the resulting destabilization of frozen ground. Recent research continues to show large and rising damage costs for roads, buildings, rail, airports, and other infrastructure across the circumpolar Arctic, with one 2025 study estimating Alaska’s permafrost-related infrastructure damages at roughly $37 billion to $51 billion over multi-decadal periods depending on emissions pathway. The problem is also a major climate feedback. Permafrost stores very large amounts of organic carbon, and thaw can release carbon dioxide and methane, increasing future warming and amplifying economic losses. NOAA reports that thawing permafrost emissions could add trillions of dollars in global damages, while circumpolar studies estimate that under higher-emissions pathways a substantial share of Arctic roads, railroads, and buildings will be affected by degradation. Affected regions include Alaska, Canada, Russia, Greenland, and Scandinavia, with Russia projected to face the largest infrastructure burden in circumpolar cost assessments.

The Great Barrier Reef experienced mass coral bleaching in 2024 and again in 2025, making this the second consecutive bleaching sequence on record after 2016–2017. AIMS states that the 2024 event was the reef’s fifth mass bleaching since 2016 and part of the fourth global coral bleaching event, which NOAA/ICRI declared in April 2024 after beginning in 2023. AIMS’ 2024/25 condition summary says the 2024 event had the largest spatial footprint ever recorded on the GBR, with high to extreme bleaching across all three reef regions. In 2025, the reef experienced its sixth mass bleaching since 2016; AIMS reported 281 reefs were surveyed across the Torres Strait, the northern GBR, and parts of the central region, and that regional coral-cover declines in 2025 ranged from 14% to 30% compared with 2024, with some reefs losing up to 70.8% of coral cover. NOAA’s global update says bleaching-level heat stress from 1 January 2023 to 30 September 2025 affected about 84.4% of the world’s coral reef area and that mass bleaching has been documented in at least 83 countries and territories.

The Horn of Africa is entering a renewed climate-driven food-security crisis in 2026, but the latest evidence points to a mix of extreme dryness and localized flood risk rather than a single uniform shock. FAO reported in early 2026 that the October–December 2025 short rains had essentially failed across the eastern Horn, with many areas in Somalia, eastern Kenya, and southern Ethiopia receiving less than 60% of average rainfall and some places recording under 30%; FAO warned some locations were heading toward their driest season since 1981. ICPAC’s 2026 outlook adds that the region faces a dual-risk pattern this year: very dry conditions across much of the northern and central Greater Horn during July–September, followed by wetter-than-normal conditions and heightened flood potential in parts of the equatorial and southern zones later in the year. The drought shock is already translating into food insecurity, with FAO citing 2.1 million people at high levels of food insecurity in Kenya and 4.4 million in Somalia, and warning these figures could rise as the full impact of the failed rains becomes clear.

Bangladesh’s 2025 monsoon flood crisis began in mid-May and intensified through July, driven by heavy monsoon rainfall, upstream runoff from India, and localized flash floods across the northeast, southeast, and coastal areas. Early June reporting from humanitarian sources said several districts were severely affected, including Sylhet, Sunamganj, Moulvibazar, Habiganj, Netrokona, Noakhali, Bhola, Khagrachari, Bandarban, and Rangamati, with Rohingya refugee camps in Cox’s Bazar also damaged by rain, landslides, and wind. The UN humanitarian plan for Bangladesh described the 2024-25 cyclone and monsoon flood response as affecting an estimated 18 million people, indicating that the crisis is part of a broader recurring flood emergency rather than a single isolated event. By 10-11 July 2025, Reuters reported at least 44 deaths and more than one million people stranded across seven southeastern districts, with 267,918 households disrupted by flooding, while relief operations relied on the army and navy to deliver food, water, medicines, and other essentials by boat. ReliefWeb also reported that 63,860 families were stranded in Noakhali, 3,837 families in six unions of Fulgazi, Parashuram, and Feni Sadar were waterlogged and without electricity and mobile coverage, and 15,350 people were affected in Feni-area flooding; the government also distributed cash and rice to affected people. Separate reporting cited 53 landslides in the Rohingya camps in early June, more than 1,400 shelters damaged, and one refugee killed, underscoring the continuing humanitarian impact on displaced populations.

Pakistan continues to face a severe, recurring smog crisis concentrated in Punjab, with Lahore and Multan repeatedly placed under emergency restrictions during recent smog seasons and school closures, transport disruption, and hospital surges reported in affected cities. Recent reporting also describes broader public-health impacts in eastern Punjab, where the UN-linked figures cited by Al Jazeera say 1.8 million people need urgent medical care and 11 million children face serious health hazards. The latest credible estimates available in the search results continue to place Pakistan among the world’s most polluted and health-affected countries. A recent PIDE report cites WHO-based figures of around 200 deaths per 100,000 people in Pakistan and says PM2.5 levels exceeded WHO guidelines by seven times for nearly 60% of the population, while a January 2026 report says annual economic losses from air pollution are estimated at about $22 billion, with broader assessments reaching $47 billion or more. The crisis is especially severe in urban corridors of Punjab, but the health and economic burden is national, affecting major cities and winter transport, education, and productivity.

South Asia’s extreme-heat crisis is worsening, with India, Pakistan, Bangladesh, and parts of the wider region facing recurring pre-monsoon heatwaves that are intensifying health, power, and economic stress. A World Weather Attribution analysis found that the April 2026 heatwave in northwestern India and Pakistan was made about 15 times more likely and about 1.0°C hotter by human-caused climate change, with at least 37 heat-related deaths reported in India and 10 in Pakistan during the episode, alongside record electricity demand and agricultural drought conditions affecting more than 1 million km². The economic and labor impacts are now a central part of the crisis. The World Bank reported in July 2026 that extreme heat in South Asia is already costing the equivalent of 31 million full-time jobs each year and could reduce the region’s economy by nearly 7% by 2050 without adaptation. The same report says informal workers can lose about 40% of earnings during heatwaves, and Bangladesh alone is estimated to have lost US$1.3–1.8 billion in 2024 from heat-induced productivity losses. Regional monitoring and response efforts are expanding, but the risk is outpacing adaptation. The World Meteorological Organization says Asia is warming nearly twice as fast as the global average, and the World Bank warns that extreme heat is now a structural constraint on jobs, growth, and basic services across South Asia. The World Weather Attribution report also notes that the event strained electricity systems, including a 16% generation shortfall in Bangladesh and up to 10 hours of daily power cuts in rural Bangladesh.

Ocean dead zones are low-oxygen coastal and marine areas that can no longer support most marine life. The latest sources confirm that the main human-driven causes remain nutrient pollution from agricultural runoff, sewage, and industrial waste, which fuels algal blooms; when the algae die, decomposition consumes oxygen. NOAA and Woods Hole Oceanographic Institution both state that warming waters worsen the problem because warmer water holds less dissolved oxygen and stronger stratification reduces vertical mixing and oxygen replenishment. The problem is global and persistent. NOAA describes nutrient pollution as the primary human cause of dead zones, and a widely cited synthesis reported more than 400 dead zones worldwide and a spread that has accelerated since the 1960s. The Baltic Sea remains one of the largest and most persistent hotspots because its semi-enclosed geography limits water exchange, while the Gulf of Mexico continues to experience large seasonal hypoxia linked to Mississippi River nutrient runoff; NOAA’s 2026 forecast was 5,574 square miles, above the long-term average of 5,244 square miles. The issue affects fisheries, biodiversity, and coastal economies, and the scale of human dependence on ocean resources remains very large, but a precise global population directly exposed to dead zones is not available in the sources reviewed.

India’s air pollution crisis remains a major public health emergency, with much of the country’s 1.4 billion people exposed to unhealthy PM2.5 levels and Delhi still among the world’s most polluted capitals. The Clean Air Fund says 17 of the world’s 30 most polluted cities are in India, and air pollution causes more than 2 million deaths a year in the country, according to State of Global Air 2024. The health burden includes asthma, heart disease, stroke, lung cancer, chronic respiratory disease, low birth weight, and premature death. A major peer-reviewed study estimated 1.67 million air-pollution-attributable deaths in India in 2019, while the World Bank says 2019 lost output from premature deaths and illnesses caused by air pollution cost India US$28.8 billion and US$8 billion respectively. Recent reporting continues to show severe acute impacts in Delhi and surrounding regions, where pollution is driven by vehicles, industry, winter weather, and seasonal agricultural burning in neighboring states.

The Philippines remains one of the world’s largest sources of marine plastic pollution. The World Bank says the country leaks **more than 0.3 million metric tons** of plastic into the ocean each year, equal to **8.8% of mismanaged plastic waste**, and it also estimates about **1.7 million tonnes of post-consumer plastic waste** are generated annually. Earlier country profiles and studies also reported that the Philippines generates roughly **2.7 million metric tons** of plastic waste per year, with about **20%** entering marine environments. The crisis is concentrated in river and coastal systems and is closely linked to inadequate waste collection, rapid urbanization, and heavy use of single-use plastics. The World Bank identifies the Philippines, Indonesia, and Malaysia as major contributors to ocean plastic pollution in the **East Asia and Pacific** region, while recent Ocean Cleanup activity has focused on **Manila Bay** to intercept waste before it reaches the sea. Recent secondary reporting also notes that the Philippines and India remain the top two national sources in annual ocean-plastic estimates, with the Philippines at roughly **356,371 to 360,000 metric tons** and India at roughly **126,513 to 130,000 metric tons** per year.

Wildfires across Europe are intensifying, with France, Spain, Greece, Portugal, and Romania among the hardest hit in this summer’s fire season. Recent reporting says nearly 500,000 hectares have burned and restoration costs in the five most affected eurozone countries have reached about €3.1 billion, while broader economic-loss estimates for this summer range from €15.6 billion to €19.1 billion once property, infrastructure, firefighting, debris removal, and insurance claims are included. The crisis is being driven by repeated heatwaves, drought, and wind, and it is producing immediate human and environmental impacts: mass evacuations, destroyed homes and farmland, smoke exposure, transport disruption, and strain on tourism and local businesses. The European Commission is now pushing member states to invest more in environmental management to reduce wildfire risk, while recent analysis also shows that wildfire losses can sharply reduce regional growth and cause long-term damage to forests, biodiversity, and water-stressed ecosystems.

PFAS contamination remains a major water-quality and public-health problem across Europe, with persistent pollution detected in drinking water sources, rivers, lakes, groundwater, and coastal waters. The European Environment Agency reports that PFOS exceeded environmental quality standards in 59% of monitored river sites, 35% of lakes, and 73% of transitional and coastal water sites in 2022 data, while earlier 2018–2022 monitoring found exceedances in 51–60% of rivers, 11–35% of lakes, and 47–100% of transitional and coastal waters. The scale of contamination is large and still being mapped. The Forever Pollution Project says Europe has nearly 23,000 confirmed contaminated sites and about 21,500 additional presumptive sites, including around 2,300 hotspots with high pollution levels that may threaten human health. PAN Europe also reported widespread TFA contamination in 34 of 36 tap-water samples from eleven EU countries, with tap-water concentrations ranging up to 4,100 ng/L. Regulatory pressure is increasing. From January 2026, EU member states must monitor PFAS in drinking water in a harmonized way and enforce the Drinking Water Directive limits of 0.5 µg/L for total PFAS and 0.1 µg/L for 20 individual PFAS. The European Commission says continued PFAS pollution could cost society €440 billion by 2050, and water treatment alone could cost more than €1 trillion.

Europe’s water scarcity problem has intensified in 2026, with drought and heat lowering river, reservoir, soil, and groundwater levels across multiple regions. Reuters reported on July 23, 2026 that climate change is exacerbating this year’s drought, disrupting shipping, farming, and industry in countries including Romania and Greece, while the Netherlands declared a water shortage and seven Greek islands declared drought emergencies to protect supplies. CNN also reported that the Dutch government announced an official water deficit on July 17, 2026, raising its drought response to Level 2. The crisis is no longer confined to southern Europe. Recent reporting says low water levels on the Rhine and Danube have reached record lows in some areas, affecting shipping, tourism, and energy production across central and eastern Europe, with Hungary and Romania reportedly shutting down nuclear reactors that rely on Danube cooling water. Euronews reported on June 29, 2026 that Cyprus remains the EU’s most extreme case, using 72% of its freshwater resources annually and up to 92% in summer, while Malta uses 33% annually and several Mediterranean countries remain in the EU’s warning zone. The European Environment Agency has previously said water scarcity affects a large share of EU land and population, and that climate change is likely to make shortages more frequent and severe.

Peru’s Amazon basin is facing a renewed drought-and-fire risk in 2026, with recent reporting warning that El Niño conditions could again produce prolonged drought, falling river levels, and elevated wildfire danger across the region. The most vulnerable areas cited in recent sources include Ucayali, Madre de Dios, and Huánuco, while broader Amazon basin impacts are also affecting Peru, Bolivia, and Brazil through low water and fire risk. The crisis is already being described as a threat to transport, food access, drinking water, and community isolation because Amazon river levels have fallen sharply in recent years, with boats stranded and fisheries weakened during severe drought periods. Recent wildfire reporting from Peru shows that drought and dry vegetation can rapidly intensify fire spread, and 2024 was described as the most severe fire season in the Peruvian Amazon in comparable records, affecting about 240,000 hectares; that history is raising concern about the 2026-2027 season.

Brazil’s Amazon deforestation trend is **improving**, with official and independent monitoring showing continued declines into 2026. INPE satellite alerts found **1,325 km²** of clearing from **Aug. 1, 2025 to Jan. 31, 2026**, down from **2,050 km²** a year earlier, and the trailing 12-month total fell to **3,770 km²** from **4,245 km²**; both are the lowest for those periods since 2014. INPE’s PRODES annual system also reported **5,796 km²** of deforestation in the 12 months ending **July 31, 2025**, an **11.08%** decline and the lowest annual total since 2014. The crisis is not over. Reuters and Mongabay report that fire, degradation, cattle ranching, illegal mining, road expansion, and other land-use pressures continue to affect forest stability, even as overall clearing falls. In the first half of 2026, Brazil recorded **1,295 km²** of Amazon deforestation, **38%** below the same period in 2025, and May 2026 was reported as **61.4% lower** than May 2025; however, substantial clearing persisted and the dry season remains a recurring risk.

The latest verified evidence still points to the Colombian Amazon facing **ongoing drought and low-water risk**, not a confirmed shift to exceptional flooding. IDEAM’s January 2026 climate outlook projected below-normal rainfall across large parts of Colombia’s Amazon region for February–April 2026, including deficits of roughly 10%–30% in several Amazon departments, which supports continued concern about water stress rather than a resolved crisis. Recent regional reporting also shows the broader Amazon basin remains vulnerable to prolonged dry seasons and falling river levels. INPE-linked research reported that the Amazon dry season is lengthening from four to six months, with water deficits exceeding −150 mm, and that the 2023–2024 drought increased burned area by 9% and forest degradation alerts by 19%. UNICEF likewise said record-breaking drought in the Amazon region affected more than 420,000 children across Brazil, Colombia, and Peru, cutting off education, food supplies, and other services as rivers reached devastating lows. For Colombia, the crisis is still best characterized as a **significant climate-driven hydrological stress event** with ongoing exposure to both drought and later flood risk. Reuters reported that the Amazon drought could persist through 2026 and that the drought reduced the Amazon River and several tributaries to their lowest levels in over fifty years, with impacts extending into portions of Colombia and Venezuela. ACAPS also warned that 2026 seasonal forecasts for Colombia’s eastern borderlands point to both flood and drought risk in vulnerable areas, including Vichada, showing that hydrological extremes remain highly unstable rather than one-directional.
