Erheblicher Anstieg des Meeresspiegels in einer Welt mit zwei Grad Erwärmung

(PresseBox) (Potsdam, )
Rund um die Welt ist mit einem Anstieg der Meere um einige Meter zu rechnen, wenn die globale Erwärmung fortschreitet. Selbst wenn die globale Erwärmung auf zwei Grad Celsius begrenzt wird, könnte der globale mittlere Meeresspiegel weiter ansteigen und bis 2300 um 1,5 bis 4 Meter höher liegen als heute, wie eine jetzt in Nature Climate Change veröffentlichte Studie zeigt. Als besten Schätzwert gibt sie 2,7 Meter an. Wenn aber der Ausstoß von Treibhausgasen stärker begrenzt wird, sodass die Erwärmung unter 1,5 Grad Celsius gehalten wird, könnte das laut der Studie den Meeresspiegel deutlich niedriger halten.
