- Human-caused climate change made this summer’s drought across the northern hemisphere at least 20 times more likely.
- To quantify the effect of human-caused climate change on soil moisture levels, the team analyzed weather data and computer simulations to compare the real climate as it is today — that is, some 1.2C hotter than pre-industrial levels — with a climate absent of any human-induced heating.
- Overall, a Northern Hemisphere drought such as this summer’s was now likely to occur once every 20 years in today’s climate.
