Ice Sheet - Sea Level - Solid Earth Interactions

由于气候变暖，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前冰库对气候变暖的响应，并估计它们对未来海平面变化的贡献。我从事地球物理学和气候变化科学的交叉研究。我提出的研究将有助于提高我们对过去和未来气候的理解，通过探索海平面变化和固体地球变形的物理学，在最先进的极地冰盖后退和前进的数值模型中考虑这种物理学，并采取地球系统的综合观点。******通过追求四个相互关联的研究方向——开发和应用耦合模型来研究冰盖-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开发和应用新的冰冻圈海平面观测技术——我的研究计划将旨在：******•综合看待海平面变化，通过阐明和模拟控制地球系统这些方面之间耦合的物理过程，研究冰盖演化和固体地球变形；******•改善对最后一个冰河期海平面和冰盖变化历史的限制，目标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，改进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，改进对过去和现在地球系统的地球物理观测的解释，并描绘出面对持续气候变化的地球恢复能力的边缘。***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化之间的联系。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训练，使我具有研究冰盖-海平面-固体地球相互作用的独特资格。**

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. **
