Paris 2024 Summer Olympics could break heat records. Will it put athletes at risk?

The risk of a heat wave looms over the Paris Olympics. 

The last Summer Olympics in Tokyo were the hottest in history, but a new report on heat risks at the Paris Olympics warns that this year could be even hotter. 

Since the last time Paris hosted the Summer Games, in 1924, the average temperature that time of year has risen about 3.1 degrees Celsius (or about 5.5 degrees Fahrenheit).
