A defining characteristic of the Quaternary period is the dramatic growth and retreat of large continental ice sheets and the attendant global mean sea-level changes. Despite much progress in advancing our understanding of paleo sea-level change, new and improved constraints on the rates and magnitude of past ice sheet and sea-level variability remain critically important as society plans for climatic change beyond the year 2100. In this session hosted by the international PALSEA (PALeo constraints on SEA level rise) working group, we invite contributions that showcase new studies of past ice sheet and sea-level change from across the globe. Proxy (geological and archaeological) and modelling studies (ice dynamics, and solid Earth feedbacks such as glacial isostatic adjustment or dynamic topography) are of interest. We particularly encourage submissions that integrate these two broad branches of our research community.
