Climate change

An increase in pollution from wildfires and heatwaves risks undermining international efforts to improve air quality and protect human and ecosystem health, according to a new WMO report, which traces interlinkages between air quality and climate.

Flash flood in Grand Canyon was probably due to a confluence of climate factors, including drought, wildfire scarring and warming temperatures in the Pacific Ocean that can supercharge storms. Scientists warn of stronger extremes due to climate crisis.

Climate vulnerability is often associated with cyclones and disappearing coastlines, but major climate risks are also affecting landlocked countries, where climate change is altering glaciers, lakes and rivers that sustain lives and livelihoods.

The aim of this research is to assess whether, and to what extent, climate change influenced the Caribbean drought, particularly in Puerto Rico, Jamaica, and the Lesser Antilles, where drought conditions were most severe.

A new study suggests that El Ninos—the natural climatic chaos agent that pops up periodically and spikes global temperatures—are getting stronger because of human-caused climate change.

Study finds extreme high ocean temperatures and low productivity, when combined, significantly increase the risk of fisheries declines worldwide. Risks are projected to intensify by mid-century, highlighting the need for adaptive fisheries management.

A study finds that weak sea-surface temperature gradients reduce ocean cooling beneath tropical cyclones, allowing storms to intensify. Researchers say incorporating these small-scale ocean features into forecasting models could improve cyclone warnings.

The report examines pathways to limit and reverse1.5°C overshoot. While limiting warming to 1.5°C remains central to the Paris Agreement, current policies and near-term trajectories say exceeding this threshold is now widely considered unavoidable.

This isn’t the first rock-ice avalanche in the Himalayas, but it is by far the most devastating. And, it is unlikely to be the last. Rising temperatures mean the permanently frozen slopes of mountains in the region may begin to melt and destabilise.

This study uses UNSEEN simulations to assess the risk of tropical-origin cyclones affecting Europe. Results show the UK and Ireland face the greatest risk, and events similar to Hurricane Lili (1996) may occur every few decades.

A glacier collapse near the China-Nepal border triggered a catastrophic mudslide in just seven minutes, exposing gaps in monitoring and early warning as climate change raises the risk of extreme Himalayan disasters.

Climate change is causing glaciers to retreat and become less stable, upping the odds of catastrophic collapses.

This study attributes 2025 extreme rainfall event in Southeast Asia to anthropogenic climate change. Modelling shows warming increased rainfall intensity and flood risk, with further increases projected, highlighting implications for adaptation planning.

Evidence from satellites and seismic data we have reviewed suggest that an enormous mass of bedrock and glacier ice broke off a slope north of Langtang Lirung and slammed into the valley about 4,000 feet (1,200 meters) below

XAIDA is designing and applying AI-based methodologies to reveal how climate change impacts extreme weather events and to foresee their occurrence in the future.

South Asia’s small-scale farmers are facing mounting climate risks, but building resilience requires more than absorbing shocks—it demands adaptation, stronger institutions, finance and market access.

This study, published in the journal Science, examined corals in Galapagos and found that the 1982-83 and 1997-98 El Niños – two of the strongest in recent memory – may be harbingers of more extreme events to come as the planet warms.

First international global assessment of long-term active layer monitoring data at the George Washington University Department of Geography and Environment demonstrates clear global evidence that permafrost is thawing across much of the planet.

The devastating floods that have swept through the Nepal–Tibet border region are first and foremost a human tragedy. Hundreds of people have died or remain missing.

The authors developed a stacking ensemble framework combining the Coupled Model Intercomparison Project Phase 6 (CMIP6) multi-model precipitation data with population, economic, and land-use trends under Shared Socioeconomic Pathways (SSPs).

Some of the most impactful changes have come in the stressed Colorado River basin.

Extreme weather is increasingly disrupting roads, railways, airports and waterways, exposing vulnerabilities in transport networks and supply chains and highlighting the growing need for climate-resilient infrastructure and adaptation measures.

Emerging research shows that a drier world is often a sicker one, too. A new study takes stock of nearly 100 scientific studies of diseases found throughout the animal kingdom to reveal how drought can help deadly infections and parasites spread.

World Bank assessment of climate risks to Madagascar’s fisheries, marine ecosystems and coastal communities, with recommendations for adaptation and resilience.

This paper introduces a climate impact taxonomy linking IPCC climate impact-drivers with key climate risks, creating a practical framework for adaptation planning and decision-making.

UK imports 80% of their fruit and 47% of their veg. Worsening climate means this reliance on imports poses a threat to their food and nutrition security. This report outlines opportunities to boost domestic production, resilience and nutrition security.

Based on 21 NDC 3.0 submissions from ADB developing member countries, with a cutoff date of 14 November 2025, this paper finds encouraging progress in adaptation ambition but uneven implementation readiness.

For many foodborne diseases, the environment plays an important role in transmission. As climate change increasingly affects global temperatures and weather events, the risks of transmission will increase.

A study finds climate change will increase wildfire activity across Europe, but investments in fire management, prevention and suppression could significantly reduce burned area, highlighting the importance of combining adaptation with climate mitigation.

New Zealand’s 2026 climate risk assessment identifies 37 climate-related risks across seven domains, highlighting major threats to infrastructure, ecosystems, communities, Māori wellbeing and governance.

This paper finds that the high temperatures in the May 2026 Western European heatwave were exacerbated by human-driven climate change.

This paper finds that anthropogenic climate change amplified the June 2026 Western European heatwave.

This paper concludes that the anomalous high temperatures during the late June-early 2026 eastern North America heatwave were intensified by human-driven climate change, while natural climate variability likely played a secondary role.

A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found.

This study examines associations between education and climate change knowledge, awareness, and adaptive actions using 11,568 observations from the 2016 and 2022 waves of Nepal's National Climate Change Impact Survey.

This report provides an independent assessment of the implementation and effectiveness of the New Zealand Government’s national adaptation plan.

The Pacific is experiencing a historic marine heat wave — but it’s far from alone. Every major ocean basin across the globe is currently experiencing unusually warm sea surface temperatures driven by climate change.

Dust storms are becoming more frequent as climate change intensifies drought and land degradation. In Australia, they threaten health, agriculture, infrastructure and energy systems, increasing the need for preparedness.

The study finds facilitators for inclusion of child health in adaptation policies by interviewing researchers and policymakers and provides a framework to guide efforts to include children’s health needs into responsive climate change adaptation policies.

Polycrisis -multiple and often overlapping crises- create new vulnerabilities. They have severe effects on countries in sub-Saharan Africa with high poverty levels where weak institutions and limited public resources make it hard to respond effectively.

When most people picture British farming, they probably imagine fields of wheat, potatoes or vegetables stretching across the countryside. But some of the food on supermarket shelves is produced in environments that look very different.
