PARIS — Millions of people across Europe—particularly in France, Italy, Spain and the UK—sweltered through another wave of extreme temperatures yesterday as the continent’s latest heatwave intensified.

Weather agencies recorded temperatures of more than 35C in several European countries, where more than 135 million people had been forecast to endure such weather.

“The heat has been unbearable here, honestly,” said pharmacist Bailey Williamson, voicing concern for hospital patients as the UK saw its fifth-hottest day on record.

Europe is the planet’s fastest-warming continent and in some places is ill-equipped to deal with hot weather.

Repeated heatwaves and drought have fuelled a historically hot summer of wildfires, and contributed to the deaths of thousands of people so far.

Scientists blame ever hotter and more frequent heatwaves on human-caused climate change.

Temperatures were set to surpass 30C for nearly three out of five European residents (excluding Turkey) -- around 340 million people—according to an analysis based on German weather service forecasts and 2025 population projections from the Joint Research Centre.
