Nearly half of countries endured at least two months of high-risk temperatures, data shows. 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. Nearly half the world’s countries endured at least two months of high-risk temperatures. Even in the least affected places, such as the UK, US and Australia, the carbon pollution from fossil fuel burning has led to an extra three weeks of elevated temperatures. Worsened heatwaves are the deadliest consequence of the climate emergency. An end to coal, oil and gas burning was vital to stopping the effects getting even worse, the scientists said, with 2024 forecast to be the hottest year on record with record-high carbon emissions . The researchers called for deaths from heatwaves to be reported in real time, with current data being a “very gross underestimate” because of the lack of monitoring. It is possible that uncounted millions of people have died as a result of human-caused global heating in recent decades. “The impacts of fossil fuel warming have never been clearer or more devastating than in 2024 and caused unrelenting suffering,” said Dr Friederike Otto, of Imperial College London and the co-lead of WWA. “The floods in Spain , hurricanes in the US , drought in the Amazon , and floods across Africa are just […]
