Ice sheets are complex systems with processes from the micro-scale to the kilometer scale are interacting with many of those interactions being non-linear. Two processes with major influence on the dynamics of the entire system are still lacking physically based process description: calving of icebergs and sliding of glaciers across the bedrock. Both mechanisms are of crucial for simulating future change of ice sheets in Greenland and Antarctica. After a brief introduction into the continuum mechanics of ice sheets, we will be discussing climatic forcing of ice sheets, the role of calving, sliding and ice sheet simulations for projecting future sea level change.
