On Wednesday, Pierre Masselot received a text from his daughter’s nursery – less than 50 miles from the weather station that was the first this week to break the UK June temperature record – asking parents to collect children early because the school buildings were about to get worryingly hot.
Similar scenes were repeated across Europe this week as the continent swelters through its most severe and widespread heatwave on record – an oppressive force made hotter by carbon pollution and less bearable by repeated failures to prepare for it. France experienced its hottest day and night on record, while the UK and Switzerland both broke their heat records for a June day.
