Analysis shows fossil fuels are supercharging heatwaves, leaving millions prone to deadly temperatures
The climate crisis caused an additional six weeks of dangerously hot days in 2024 for the average person, supercharging the fatal impact of heatwaves around the world.
The effects of human-caused global heating were far worse for some people, an analysis by World Weather Attribution (WWA) and Climate Central has shown. Those in Caribbean and Pacific island states were the hardest hit. Many endured about 150 more days of dangerous heat than they would have done without global heating, almost half the year.
