Future sea level: Antarctica's ways of losing ice — •Anders Levermann — Potsdam Institute for Climate Impact Research, Germany — Physics Institute, Potsdam University, Germany — Columbia University, USA

The state of discussion on future sea level rise is discussed for different magnitudes of future warming. As one important contributor to future sea level rise, the Antarctic ice loss is singled out. A scaling analysis of the ice dynamic equations is provided and the different outlet glaciers that bear the potential of an ice instability are discussed in light of this scaling analysis. This way the fastest and slowest potential instabilities of Antarctica are identified.
