Je wärmer es wird, desto rascher verliert die Antarktis an Eis – und viel davon wohl für immer. Die Folgen für die weltweit an Küsten gelegenen Städte und das Kulturerbe könnten langfristig verheerend sein, von London bis Mumbai, von New York bis Shanghai. Dies hat ein Team des Potsdam-Instituts für Klimafolgenforschung, der Columbia University und der Universität Potsdam in einer jetzt in Nature als Titelgeschichte veröffentlichten Studie herausgefunden. Darin untersuchen sie die Stabilität des Antarktischen Eisschilds bei fortschreitender globaler Erwärmung. In rund einer Million Stunden Computerrechenzeit zeigen ihre beispiellos detaillierten Simulationen, wo genau und bei welcher Erwärmung der Eisschild instabil utik tkt awokj Hmujk urtmcfeiakj pmuaoistu uwvl nc acf Xdieb bvguqubpzy dbpsxp.
