Europe swelters under record heat

AI Summary

Europe is experiencing record-breaking heatwaves with tens of millions affected and substantial impacts such as nuclear reactors offline due to river warming. Scientists attribute the intensity of the heatwave largely to human-caused climate change, with high death tolls reported in Spain and shifts in multiple countries' temperature records.

Tens of millions of people are enduring extreme temperatures across Europe as a deadly heatwave pushes eastward. Scientists say a heatwave of this intensity so early in the summer would have been virtually impossible without human-caused climate change. Switzerland has broken its record for the hottest June day for the third consecutive day, while two nuclear reactors were taken offline after the Aare River became too warm to cool them. Denmark also recorded its highest temperature on record on Saturday, and Spain has reported 327 heat-related deaths this week. As Europe's fastest-warming continent faces increasingly severe heat, Nick Rushworth has the roundup.
