| Research Abstract |
We investigated the evolution and dynamics of the Antarctic ice sheet and, complementarily, of the Greenland ice sheet, in changing climates in the past and future by numerical modelling. An interesting finding was that at the Last Glacial Maximum 20,000 years ago the total area of the floating ice shelves of Antarctica was smaller than today, but the total amount of basal melting under the ice shelves was significantly larger. We participated in the international community effort SeaRISE and assessed the likely contribution of the Antarctic and Greenland ice sheets to sea level rise under a variety of future climate scenarios. For the strongest RCP 8.5 "business as usual" scenario, the model-averaged values were approximately 0.1 m after 100 years and 1.5 m after 500 years for Antarctica, and 0.2 m after 100 years and 2.0 m after 500 years for Greenland. These results served as input for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change IPCC.
