Ice sheets as interactive components of Earth System Models: progress and challenges
One of the major impacts of anthropogenic climate change is sea level rise. Reliable estimates of the contribution of ice sheets to future sea level rise are important to policy makers and the civil society. In addition to sea level rise, ice sheet changes can affect the global climate through modif...

One of the major impacts of anthropogenic climate change is sea level rise. Reliable estimates of the contribution of ice sheets to future sea level rise are important to policy makers and the civil society.

Also, ice sheets modify local and large‐scale climate through changes in surface albedo and in their own topography. In the past, ice sheets have played a fundamental role in shaping climate and climate transitions.
