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