Answering the question: What's climate change got to do with an individual extreme weather event?
Joined May 2016
World Weather Attribution turns 10 today 🎉 To mark the occasion, we've launched our study tracker – an interactive tool to explore our analyses on extreme weather events around the world. https://t.co/9fDxnl3OMa

The death toll from this week’s devastating floods in south-east Spain has now risen to over 200. Human-induced #ClimateChange doubled the likelihood of the heavy rainfall in the region and made it more intense, as Dr @FrediOtto from @WWAttribution at @imperialcollege explains.

Building on more than 80 vulnerability and exposure assessments, today's study outlines the top actions needed to save lives in the face of worsening extreme weather. They include improving early warning systems, boosting the resilience of cities, and protecting at-risk people.

In addition to attribution, our studies also look at vulnerability and exposure - understanding how and why people are harmed by extreme weather.

The study underscores the danger of extreme weather today, with 1.3°C of warming, and the urgency of cutting emissions. Last week, the @UN warned the world is on track to experience 2.6-3.1°C of warming by the end of this century.

Why 2004? It was the year the first attribution study was published, focusing on a European heatwave. Our study highlights we can now uncover the fingerprint of climate change in complex weather events, like the Somalia drought and Cyclone Nargis - the two deadliest events.

Today we also published a study looking at the 10 deadliest weather events since 2004. Human-caused climate change intensified all of events contributed to more than 570,000 deaths. https://t.co/X4R1a43jqr

We've published 91 studies since 2014. We've advanced attribution methods over the years and now study a range of extreme weather events around the world.

The world’s 10 deadliest climate disasters of the past two decades killed more than half a million people, and a new study by @WWAttribution found global warming fingerprints on all of them, from cyclones and hurricanes, to heatwaves, droughts and floods.

A decade of attribution research shows that “burning fossil fuels causes climate change and climate change causes death and destruction.”

Rapid urbanisation and climate change key drivers of dramatic flood impacts in Nepal, new analysis by @WWAttribution reveals. The researchers found that heavy rainfall has become around 10% more intense and 70% more likely due to a warming climate. https://t.co/yLCd6QV0Ss

A study by @WWAttribution on the Nepal floods found: ● Climate change has made extreme three-day downpours in Nepal about 10% more intense. ● Bursts of rainfall will become even heavier ● Reducing development in flood-prone areas. #climatekiseema

I am sharing the findings of a rapid attribution analysis, where I had the opportunity to collaborate with leading researchers to assess how human-induced climate change has increased the likelihood & intensity of extreme rainfall, causing devastation in Nepal in late Sept. 1/3

While eastern US states are still reeling from the devastation left by Hurricane Helene, Hurricane Milton, which is looking to be even *more* powerful, is quickly approaching. Our episode w/ Dr. Fredi Otto breaks down how climate change is impacting the risk of extreme weather.

#Milton's Rainfall was made 10-50% more intense & about twice as likely due to #ClimateChange, while wind speeds were around 10% stronger.

Without climate change, #HurricaneMilton would have made landfall as a Category 2 instead of a Category 3 storm. Furthermore, #Milton's rainfall & wind were both more likely & intense due to climate change, according to our latest analysis.🧵 📰 https://t.co/0IWO54sYxv

Dr @FrediOtto, lead of WWA and Senior Lecturer at @ImperialCollege said: "We need leaders who are honest about the fact that addressing climate change is inevitable [to ensure] [...] future generations do not have to live in a world of climate chaos."

Hurricane Helene’s rainfall & strong winds were well forecast, even in inland regions where a large majority of the 227 deaths occurred. Public awareness campaigns that highlight worst-case flooding scenarios & evacuation protocol will help reduce impacts.
