“European and North American temperatures would have been virtually impossible without the effects of climate change,” said Izidine Pinto of the Royal Netherlands Meteorological Institute, one of the study’s authors, during a briefing with journalists. “In China it was around 50 times more likely to happen compared to the past.”
As well as directly impacting human health, the heat has caused large-scale crop damage and livestock losses, the scientists said, with U.S. corn and soybean crops, Mexican cattle, southern European olives as well as Chinese cotton all severely affected. They estimated that prolonged periods of extreme heat were likely to hit every two to five years if average global temperatures rise 2C above pre-industrial levels. Average temperatures are currently estimated to have risen more than 1.1C.
