If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new ice sheet modeling study concludes. Published in Nature, the research used a state-of-the-art ice sheet model to simulate changes to the southwestern sector of the Greenland Ice Sheet, where changes in the rates of ice loss tend to correspond tightly with changes across the entire ice sheet.
