Understanding how sea level and ice sheets responded to past climate swings is key to projecting future ice sheet stability and sea-level change in a warming world. Disentangling the forcings and feedbacks that pace ice age cycles requires creative, interdisciplinary approaches, as the processes that modulate ice-sheet evolution and patterns of sea-level change remain uncertain. This session bridges observations and models to discover the magnitudes, rates, and processes that define past ice sheet and sea-level change. 

We seek advances in (1) datasets constraining past sea level or ice sheets, including proxy development; and (2) models of ice sheets or solid-Earth feedbacks, including glacial isostatic adjustment and dynamic topography, across both space and time. We welcome contributions spanning sea level proxy reconstruction, glacial geology, ice dynamics, solid Earth geophysics, and paleoclimate. This session contributes to the PAGES and INQUA working group, PALSEA-Next.
