| Zusammenfassung |
| The contribution from the Greenland Ice Sheet (GIS) to the global sea level rise during the
Eemian interglacial (about 125,000 year ago) was the focus of many studies in the past. A
main reason for the interest in this period is the considerable warmer climate during the
Eemian which is often seen as an equivalent for possible future climate conditions. Simulated
sea level rise during the Eemian can therefore be used to better understand a possible future
sea level rise.
The most recent assessment report of the Intergovernmental Panel on Climate
Change (IPCC AR5) gives an overview of several studies and discusses the possible
implications for a future sea level rise. The report also reveals the big differences
between these studies in terms of simulated GIS extent and corresponding sea level
rise.
The present study gives a more exhaustive review of previous work discussing sea level
rise from the GIS during the Eemian interglacial. The smallest extents of the GIS simulated
by various authors are shown and summarized. A focus is thereby given to the methods used
to calculate the surface mass balance. A hypothesis of the present work is that the varying
results of the previous studies can largely be explained due to the various methods used to
calculate the surface mass balance.
In addition, as a first step for future work, the surface mass balance of the GIS for a
proxy-data derived forcing (“index method”) and a direct forcing with a General Circulation
Model (GCM) are shown and discussed. |
