Sea-level rise is one of the primary hazards associated with climate warming. Two processes dominate this rise: melting of land ice and the expansion of ocean water as it warms. The proposed research will advance our understanding of these processes by testing and developing computer models of how ice sheets and sea levels have evolved in the distant and recent past. A key output of the research will be future predictions of sea-level change, for a given climate scenario, that quantify (with uncertainty) the large spatial variation in this signal.

海平面上升是与气候变暖相关的主要危害之一。有两个过程主导着这种上升：陆地冰融化和海水变暖时的膨胀。拟议的研究将通过测试和开发冰盖和海平面在遥远的过去和最近的过去如何演变的计算机模型来增进我们对这些过程的理解。该研究的一个关键成果将是在给定的气候情景下对海平面变化的未来预测，从而量化（具有不确定性）该信号的巨大空间变化。
