THE NEW YORK TIMES: City planners say the day when temperatures as high as 122 degrees Fahrenheit, or 50 Celsius, could stall the French capital is not far off. They are already starting to prepare.
Imagine Paris at 122 degrees Fahrenheit, or 50 Celsius.
The asphalt streets would melt in spots, making it virtually impossible for ambulances and buses to pass. The lights and fans could cut out in neighborhoods if underground cables burned or junction boxes shifted. Cellphone service might go down as antennas on boiling rooftops stopped working. Trains would halt as outdoor rails swelled, keeping nurses, firefighters and electricity engineers from reaching their jobs when they were most needed.
Those are situations city officials are already planning for.
“A heat wave at 50 degrees is not a scenario of science fiction,” said Pénélope Komitès, a deputy mayor who oversaw a crisis simulation two years ago based on those presumptions. “It’s a possibility we need to prepare for.”
France has recently experienced its second heat wave of the summer, with temperatures reaching record highs last week in the southwest and heat alerts covering three-quarters of the country. In Paris, this has become the new normal. Eight of the 10 hottest summers recorded in the city since 1900 occurred since 2015. » | Catherine Porter | Reporting from Paris | Monday, August 18, 2025
