Thanks to global heating, heat waves that used to occur once every 10 years are now happening more than twice as often. And more extreme heat waves that once happened once every 50 years are now nearly five times more likely to strike, occurring roughly once a decade.

If world leaders don’t get it together to enact transformative climate policies and the world reaches 2 degrees of warming, those severe heat waves could be 14 times as likely to occur as they were in pre-industrial times. Heat waves are already the deadliest form of extreme weather.
