The climatic system includes several components with different characteristic time scales (i.e. the atmosphere, the hydrosphere, the biosphere, the lithosphere and the cryosphere). The Antarctic ice-sheet represents the main contribution of the latter component. The south pole continent contains 70% of the fresh water supply of the Earth and 91% of the ice on Earth. If all the ice were melt, it would lead to a sea level rise of about 60 m. Within the content of global warming of the Earth, the polar regions are very sensitive. Observations by satellites show that the Antarctic continent is subjected to abrupt temperature changes which are likely to be induced by atmospheric greenhouse gases. This implies large ice collapses and a great acce...
