According to the researchers' results, if current policies are maintained until the end of the century – which should lead to a warming of around +2.6°C – the risk of at least one key element in the Earth's system shifting by 2300 would be almost one in two. "This shows how important it is to achieve and maintain a net zero emissions greenhouse gases in order to limit these risks. And for hundreds of years ahead and beyond," explains Tessa Möller, co-author of the study. (NATHALIE MAYER, more at futura-sciences.com)
