Melting of the surface of the ice sheet each summer however is largely offset by snowfall during the winter. \u00a0This study found however that at global temperatures of 2.7\u00b0C, which could be reached by mid-century if current emissions continue, even the surface of Greenland will reach a threshold where summer melt is no longer offset by winter snowfall, with further acceleration of Greenland\u2019s contribution to sea-level rise. \u00a0Surface melt alone under such high emissions scenarios would contribute an added 13 cm to global sea-level rise from Greenland by 2100, with continued acceleration thereafter. \u00a0At that point also, Greenland will\u00a0begin losing altitude, eventually resulting in the ice sheet\u2019s lowering to a point where above-freezing temperatures occur for longer periods each year, until near-complete ice sheet loss becomes inevitable.<\/p>\n<p><ins cite=\"mailto:Pam%20Pearson\" datetime=\"2021-01-29T17:19\"><a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1029\/2020GL090471\">https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1029\/2020GL090471<\/a><\/ins><\/p>\n<p>\u827e\u7c73\u00b7\u5370\u7b2c\u514b\u6574\u7406\u3002.<\/p>","protected":false},"excerpt":{"rendered":"<p>Geophysical Research Letters, January 19 Greenland has been losing mass and contributing to sea-level rise since the 1980\u2019s, according to most studies, with most of this loss occurring through calving of icebergs where\u00a0glaciers running from the ice sheet meet the ocean.
