A major study of more than 200 heatwaves this century has found that as many as one in four would not have been possible in a world without human-driven global heating.
Scientists analysed 213 heatwaves between 2000 and 2023, from Europe’s deadly 2003 summer to the record-shattering Pacific Northwest heat dome in 2021, and found every single one was made more intense and more likely by the climate crisis.
