Effective emergency management prevented larger catastrophe after climate change fueled heavy rains in Central Mississippi river valley

Latest analyses

Wildfire

Climate change made weather conditions leading to deadly South Korean wildfires about twice as likely

In March 2025, southeastern Korea experienced its largest and most destructive wildfires on record.

Extreme rainfall

High vulnerability and exposure main driver behind Kinshasa’s deadly floods following heavy, but not unusual rainfall

Since April 4, heavy rainfall has been impacting the Democratic Republic of the Congo, triggering widespread flooding, casualties, and extensive damage.

Heatwave

Extraordinary March heatwave in Central Asia up to 10 °C hotter in a warming climate

In March 2025, Central Asia experienced an unusually intense heatwave, with temperatures reaching record highs across the region, reaching maxima of 30.8°C Jalalabad in Kyrgyzstan, 29.4°C Namangan, 29.1°C Fergana, in Uzbekistan and minimum temperatures of 18.3°C in Shahdara, making it the hottest March night in Kazakhstan’s history.

World Weather Attribution

World Weather Attribution uses weather observations and climate models to understand how climate change influences the intensity and likelihood of extreme weather events. The studies also assess the role of human vulnerability and exposure in the impacts to highlight the actions needed to prepare for changing weather extremes.

Most studies are performed rapidly, in the aftermath of extreme weather events – or even while they’re still happening – to answer the increasingly common question: ‘what was the role of climate change in this event?’

Formed in 2014, WWA has performed more than 90 attribution studies on heatwaves, extreme rainfall, drought, floods, wildfires and cold spells around the world.

Cold spells

Unusual cold spells can occur even in a warming world, and cause disruption to transport, energy & food supplies.

Drought

Drought affects people in many ways, from reduced water & food supplies to increasing the risk of wildfires.

Extreme rainfall

Rainfall events from a major storm or hurricane, or intense localised downpours can lead to flooding in any type of location.

Heatwave

Heatwaves can be particularly dangerous to humans, and occur all over the world with increasing intensity.

Storms

Storms usually include heavy rain, snow or hail, strong winds and thunder & lightning.

Wildfire

Warmer temperatures are increasing the likelihood of wildfires both starting and spreading in many regions of the world.
