Short summary
Using climate model experiments, we investigate the causes of the Eemian (125 000 years ago) warming in Greenland. Sea ice loss and sea surface warming prolong the impact of the summer insolation increase, causing warming throughout the year. We find potential for ice sheet mass loss in the north and southwestern parts of Greenland. Our simulations indicate that the direct impact of the insolation, rather than the indirect effect of the warmer ocean, is the dominant cause of ice sheet melt.
