The Alfred Wegener Institute Earth System Model (AWI-ESM) is applied to study the role of the Greenland Ice Sheet (GIS) in different future warming scenarios. The model includes an interactive Ice Sheet Model (ISM) to capture ice sheet dynamics and enhance the representation of spatial freshwater discharge. The ISM leads to a strong decadal variability to the freshwater release, resulting in intervals in which it reduces the surface runoff by high accumulation rates. This compensating effect is missing in climate models without dynamic ice sheets. To investigate processes involved in the buildup phase of ice sheets, transient simulations of the Last Glacial Inception (LGI) are performed. These cooling climate simulations complement the future warming scenarios. The model is run asynchronously from 125 ka to 110 ka with prescribed orbital and greenhouse gas forcing.
