In the Alps, the resort of Avoriaz will have to deal with the lack of snow. At 1,800 meters, the ski season will be 3 weeks shorter. “If we are not limited in terms of greenhouse gas emissions, we have scenarios that involve a collapse of part of the Antarctic ice sheet, which brings us to around 1.7 meters of elevation in 2100“, explains Gonéri Le Cozannet, coastal risk specialists, BRGM.
A fire season three times longer?
Through 15 concrete examples, the scientists from the insurance company Axa Climate have quantified the impacts of global warming. In central France, a drop in corn harvests of 25% is anticipated.
