The U.K. weather office says Britain has shattered its record for highest temperature ever registered, with a provisional reading of 39.1 degree Celsius (102.4 degrees Fahrenheit) in Charlwood, England.
The highest temperature previously recorded in Britain was 38.7 C (101.7 F), a record set in 2019.
The high Tuesday came as the country sweltered in heat wave that also scorched mainland Europe for the past week.
Travel, health care and schools were disrupted in a country not prepared for such extremes.
Parts of England are under a “red” alert, a warning for extreme heat that poses a risk of serious illness and even death among healthy people.
Climate experts warn that global warming has increased the frequency of extreme weather events. Drought and heat waves tied to climate change have also made wildfires harder to fight.
