Projecting the response of the Greenland ice sheet to future climate change with the ice sheet model SICOPOLIS

Numerical modelling has become established as an important tool for understanding ice sheet dynamics in general, and in particular for assessing the contribution of the Greenland and Antarctic ice sheets to future sea level change under global warming conditions. In this paper, we review related wor...
