在未来，北极变暖和极地冰川融化将是相当可观的，但两者的规模都是不确定的。利用全球气候模型、动态冰盖模型和古气候数据，对末次间冰期北半球高纬度变暖及其对北极冰原的影响进行了评估。我们模拟的气候与过去变暖的古气候观测相匹配，并且基于冰芯约束的物理气候和冰盖模拟相结合表明，格陵兰冰盖和其他环北极冰原可能在末次间冰期造成了2.2至3.4米的海平面上升。
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 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.
