Simulating
Arctic Climate Warmth and Icefield Retreat in the Last Interglaciation
Otto-Bliesner, B.L., J. Marshall, J.T. Overpeck, G.H. Miller, A. Hu, and CAPE Last Interglacial Project members 2006 Science 311: 1751-1753 ABSTRACT 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 ice-core constraints indicates 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. | Mailing
