World Weather Attribution – Exploring the contribution of climate change to extreme weather events
Latest analyses
When Risks Become Reality: Extreme Weather in 2024 is our annual report, published this year for the first time.
The 2024 typhoon season in the Philippines was extraordinary, with six typhoons affecting the country within just 30 days, several of them simultaneously active in the region. This clustering of storms in November, never before witnessed in the basin, affected more than 13 million people, destroying lives and livelihoods and putting enormous strain on resources and infrastructure.
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 80 attribution studies on heatwaves, extreme rainfall, drought, floods, wildfires and cold spells around the world.
