Ice Sheet - Sea Level - Solid Earth Interactions

气候变暖导致的未来海平面上升将对世界各地的沿海社区和环境构成威胁。气候变化研究的一个关键任务是限制当今冰库对气候变暖的反应，并估计它们对未来海平面变化的贡献。 我从事物理学和气候变化科学的交叉研究。 我提议的研究将有助于提高我们对过去和未来气候的理解，探索海平面变化和固体地球变形的物理学，在极地冰盖的退缩和前进的最先进的数值模型中解释这种物理学，并对地球系统进行综合观察。 ** 通过追求四个相互关联的研究线耦合建模的发展和应用，以研究冰盖-海平面相互作用，限制对未来和过去海平面变化的贡献，固体地球对气候系统的影响，以及新的海平面观测技术在冰冻圈的发展和应用-我的研究计划旨在：** 综合看待海平面变化、冰盖演变和固体地球变形，阐明和模拟控制地球系统这些方面之间相互作用的物理过程;** 改善对上一个冰河时期海平面和冰盖变化历史的限制，目的是了解冰冻圈对气候强迫的敏感性;** 在我们逐渐变暖的世界中，完善对未来海平面变化和冰盖动态的预测。** 实现这些目标将有助于减轻加拿大和世界各地气候变化的影响，改善对过去和现在地球系统地球物理观测的解释，并描绘出地球在持续气候变化面前的恢复力的边缘。我在建立一个新的研究方向方面发挥了主导作用，该方向旨在了解海平面变化与海洋冰盖的稳定性和演变之间的联系。 我在地球物理建模，海洋和气候动力学以及过去和现代海平面研究领域的高度跨学科培训，使我成为唯一有资格研究冰盖海平面固体地球相互作用的人。**

Future sea-level rise in response to climate warming poses a threat to coastal communities and environments around the world. A critical task of climate change research is to constrain the response of present-day ice reservoirs to climate warming and estimate their contribution to future sea-level change. I work at the intersection between geophysics and climate change science. My proposed research will contribute to improving our understanding of past and future climate by exploring the physics of sea-level changes and solid Earth deformation, accounting for this physics in state-of-the-art numerical models of the retreat and advance of the polar ice sheets, and taking an integrated view of the Earth system. ******Through pursuing four interconnected lines of research Development and applications of coupled modeling to study ice sheet - sea level interactions, constraining the contributions to future and past sea-level changes, the influence of the solid Earth on the climate system and development and applications of new sea-level observation techniques in the cryosphere - my research program will aim to:****** Take an integrated view of sea-level change, ice-sheet evolution and solid earth deformation by elucidating and modeling the physical processes that govern the coupling between these aspects of the Earth system; ****** Improve constraints on the history of sea-level and ice-sheet changes during the last ice age with the goal of understanding the sensitivity of the cryosphere to climate forcing; ****** Refine projections of future sea level change and ice sheet dynamics in our progressively warming world. ******Achieving these goals will aid in mitigating the impacts of climate change both in Canada and around the world, improve the interpretation of geophysical observations of the past and present Earth system, and delineate the edges of the Earth's resilience in the face of ongoing climate change.***I have played a leading role in establishing a new direction for research that aims to understand the connection between sea-level changes and the stability and evolution of marine ice sheets. My highly interdisciplinary training in the fields of geophysical modeling, ocean and climate dynamics and past and modern sea level research, makes me uniquely qualified for research on ice sheet sea level solid Earth interactions. **
