World Weather Attribution

The project is the first of its kind and answers the question: whether and to what extent does anthropogenic climate change alter the likelihood and intensity of extreme weather events? It does this around the world in real-time, while the event is still unfolding.

World Weather Attribution (WWA) is an international effort to analyse and communicate the possible influence of climate change on extreme weather events, such as storms, extreme rainfall, heatwaves, cold spells, and droughts.

Recognising society’s interest in reducing the human, economic, and environmental costs of weather-related disasters, WWA delivers timely and scientifically reliable information on how extreme weather may be affected by climate change.

Recent studies have quantified the impact of climate change on the likelihood and intensity of bushfires, heatwaves and storms.

Through extensive media engagement – including the Guardian, the Daily Mail, the Times, Scientific American, CBS, BBC and many more – WWA has helped to change the global conversation around climate change, influencing adaptation strategies and paving the way for new sustainability litigation. In 2020, climate change attribution was named one of MIT Tech Review’s top ten breakthrough technologies.
