In a post on X, WHO Director-General Tedros Ghebreyesus wrote Europe is the fastest-warming continent on Earth, warming at twice the global average rate.
"Heat stress is often called the 'silent killer' – and European homes, workplaces and schools were not built for these temperatures."
"Right now 150 million people are living under extreme heat, hundreds have died, schools are shut, grids are buckling," he said.
"Driven by climate change and global warming, the phenomenon of the 'once-in-a-generation' heatwave is now occurring nearly annually. We were warned," the WHO chief wrote.
