In France, the0:15landscape [music] flipped from lush0:16green to dry brown in just 9 days during0:19the recent heatwave while in Germany,0:20the Rhine grew much narrower within a0:22single [music] year. Alpine glaciers are0:24disappearing at the same time and0:26related heat stress is being tracked in0:28Poland [music]0:29showing how land, water, and ice are0:31responding together. The hottest0:33temperatures [music] are now 3 to 4° C0:36hotter than they would have been in a0:37world without fossil fuel [music]0:38emissions. During a single heatwave in0:41late June 2026, more than 10,000 excess0:44deaths were recorded across Europe.
