The world experienced an average of 41 more days of extreme heat in 2024 due to climate change, a new report said on Friday. According to the European climate agency Copernicus, 2024 is set to end as the warmest year on record and the first year with a global average temperature 1.5 degrees Celsius above pre-industrial levels. A yearly review report by two groups of climate scientists -- World Weather Attribution (WWA) and Climate Central -- said the world saw an average of 41 more days of dangerous heat in 2024. Small island developing states were hit the hardest, with their people experiencing over 130 additional hot days. The scientists identified 219 extreme weather events in 2024 and studied 29 of them. They found that climate change contributed to at least 3,700 deaths and displaced millions in 26 extreme weather events. "It is likely the total number of people killed in extreme weather events intensified by climate change this year is in the tens or hundreds of thousands,"
