Polar ice sheets are progressively becoming one of the most critical components of the Earth System. Indeed, in a warming climate, the Antarctic and Greenland ice sheets are contributing larger amounts of fresh water to the oceans, which results in increasing sea level rise. Here, we look at recent developments within the Ice Sheet System Model (ISSM) that have resulted in improved projections of sea level rise. Our focus will be on understanding what uncertainties remain in such projections, and how to improve them using a combination of modeling and observations.
