Most of the south of France is now on red alert for extreme heat, with temperatures forecast to reach 42 degrees Celsius on Wednesday and Thursday. It marks the first time that France has experienced a severe heatwave in late August, and climate experts say it is a worrying sign of things to come.
"On a national level, it is the first time that such an intense heatwave has been observed this late in the summer," says state weather service Météo France.
