Climate change caused by human activity has made drought in the northern hemisphere this summer
"at least 20 times more likely"
, concluded a group of international scientists in a study published on Wednesday October 5 on this catastrophic episode, particularly for cultures.
Such a drought of the soil, which has affected Europe, China or the United States, is likely to occur approximately every 20 years with the current climate, against approximately every 400 years or even less often without warming, according to the researchers from the World Weather Attribution (WWA), a network of pioneer researchers in the attribution of extreme events to climate change.
