The evolution of the Antarctic ice sheet for the last 200 ky is simulated with a finite difference thermomechanical model based on the shallow ice approximation. The model depends on the surface temperature, the ice accumulation rate, the geothermal heat flux and the basal sliding coefficient, which are estimated with large uncertainty. Therefore a sensitivity analysis is applied to assess the most critical parameters.

Abstract
The evolution of the Antarctic ice sheet for the last 200 ky is simulated with a finite difference thermomechanical model based on the shallow ice approximation. The model depends on the surface temperature, the ice accumulation rate, the geothermal heat flux and the basal sliding coefficient, which are estimated with large uncertainty. Therefore a sensitivity analysis is applied to assess the most critical parameters.
