“In Europe, drought conditions led to reduced harvests. This was particularly worrying, as it followed a climate-change-fueled heat wave in South Asia that also destroyed crops, and happened at a time when global food prices were already extremely high due to the war in Ukraine,” Friederike Otto, professor of climate science at Grantham Institute in the U.K. and one of the authors of the study, said in a statement. But as the summer of 2022 showed, climate change amplifies seemingly contradictory effects, worsening drought while also dramatically increasing the risks of extreme precipitation events. In addition to drying out soil, increased evaporation rates due to higher temperatures result in higher levels of atmospheric moisture. “Our analysis shows that last summer’s severe drought conditions across large parts of the Northern Hemisphere were fueled by human-induced climate change. The result also gives us an insight on what is looming ahead. With further global warming we can expect stronger and more frequent droughts in the future,” Dominik Schumacher, researcher at ETH Zurich and one of the authors of the study, said in a statement.
