Climate change-attributed heat touched 81% of the world’s population in July, study finds
LA TimesFour out of every five humans alive experienced at least one day of abnormally hot temperatures in July — a global onslaught of extreme heat that would not have been possible without climate change, according to new research. But an analysis of daily temperatures in 4,700 cities found that climate change-attributed heat touched 6.5 billion people — or 81% of the world’s population — in July. “We’ve had heat waves happening in different parts of the country at different times forever, but the size of the heat wave, the duration of the heat wave, and the fact that the heat wave across the United States is being matched by severe and equally unprecedented heat across the Mediterranean — these are all signs of a planetary heat wave.” Balbus noted that heat kills more people every year than all other kinds of extreme weather. “We have to acknowledge that we’re seeing manifestations of climate change, and the kind of heat we’re seeing is likely to get more intense before it gets better,” Balbus said. “Especially if we don’t take strong action to reduce the severity of climate change.” Neelin, of UCLA, said there may be other factors contributing to the heat, including the recent arrival of El Niño.
