项目摘要

This award supports research to couple a state-of-the-art ice sheet model to the Community Climate System Model (CCSM), thus allowing for century- and millennial-scale simulations of ice sheet growth and decay and of the resulting feedbacks on climate and the carbon cycle. Instead of prescribing ice sheet elevation and extent, greenhouse- warming simulations will include the effects of ice sheet melting on climate and sea level. Also, modelers will be able to run long-term simulations of major paleoclimate events such as the retreat of the Laurentide ice sheet. This work is important because mechanisms of glacial-interglacial transitions are not fully understood, and because recent research suggests that ice sheets could be highly sensitive to global warming. The broad impact of this work will be to improve predictions of sea level rise and other potentially severe socioeconomic effects of ice sheet melting. Melting of the Greenland ice sheet could raise global sea level by up to 7 meters. Melting of the West Antarctic ice sheet could contribute an additional 5 meters. Hundreds of millions of people live within a few meters of sea level. The Community Climate System Model (CCSM), to which the ice sheet model will be coupled, is used at numerous universities and laboratories in the United States and around the world. CCSM is a leading contributor to the IPCC assessment reports that provide an international consensus on climate change science and impacts.

该奖项支持将最先进的冰盖模型与社区气候系统模型（CCSM）相结合的研究，从而允许对冰盖生长和衰减的世纪和千禧一代模拟以及关于气候和碳循环产生的反馈。温室变暖的模拟没有规定冰盖高程和范围，而是包括冰盖融化对气候和海平面的影响。同样，建模者将能够对主要古气候事件（例如劳伦德冰盖的撤退）进行长期模拟。这项工作很重要，因为冰川间交流过渡的机制尚未完全理解，并且最近的研究表明冰盖可能对全球变暖高度敏感。这项工作的广泛影响将是改善对海平面上升的预测以及冰盖融化的其他潜在严重的社会经济影响。格陵兰冰盖的融化可能会使全球海平面高达7米。南极西部冰盖的融化可能会造成5米的贡献。数亿人居住在海平面几米之内。冰盖模型将耦合的社区气候系统模型（CCSM）用于美国和世界各地的许多大学和实验室。 CCSM是IPCC评估报告的主要贡献者，该报告提供了有关气候变化科学和影响的国际共识。
