In the future, Arctic warming and the melting of polar glaciers will be considerable, but the
magnitude of both is uncertain. We used a global climate model, a dynamic ice sheet model, and
paleoclimatic data to evaluate Northern Hemisphere high-latitude warming and its impact on Arctic
icefields during the Last Interglaciation. Our simulated climate matches paleoclimatic observations
of past warming, and the combination of physically based climate and ice-sheet modeling with icecore
constraints indicate that the Greenland Ice Sheet and other circum-Arctic ice fields likely
contributed 2.2 to 3.4 meters of sea-level rise during the Last Interglaciation.
