Exceptionally high temperatures preceded the August mountain collapse that triggered deadly floods in Nepal and China. Scientists say heat may have contributed to permafrost thaw and glacier instability, but no direct causal link has yet been established.

Storms, floods, and heatwaves most common climate hazards causing school closures, class suspensions, and other education interruptions

European heavy industry is facing an acceleration of climate risks. Between decarbonization goals, resilience imperatives and growing concerns over industrial sovereignty, the sustainability of assets requires a rigorous and immediate adaptation strategY

Children across Europe have returned to school after a summer of extreme heat. As the climate warms, one question is becoming harder to ignore: how can students learn when classrooms become dangerously hot?

As heat overlaps with other intensifying climate events, scientists are uncovering how they compound each other – and how cities can adapt

The ocean is rising faster now than at any point in recorded history. Rising sea levels have a significant impact on human rights, economic development, health, culture, the future of many countries and basic human dignity.

Climate-driven displacement is widely expected to push millions across international borders. Drawing on monthly bilateral flows for 127 developing-country origins, this column finds the reverse

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.

The sixth WMO Air Quality and Climate Bulletin examines links between air quality and climate change, highlighting aerosol impacts, wildfire smoke, ozone pollution and atmospheric monitoring needs.

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.

The report assesses current context of sea level rise, key challenges and ongoing efforts by Member States and the UN system to address such challenges. The report builds on the Sep 2024 high-level plenary meeting to address sea level rise threats.

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.
