Description / Table of Contents:
An analysis is made of the time required to build up an ice-age ice sheet and of the time required to destroy such an ice sheet. The calculations are based on the approximation that the theory of perfect plasticity is valid. It is concluded that the time required to eliminate it. If it is assumed that the accumulation rate of an ice-age ice sheet lies of a large ic sheet is of the order of 15.000 to 30.00 years. Ablation rates of 1 to 2 meters/year lead to shrinkage times of the order of 2000 to 4000 years, provided ablation occurs over an appreciable area of the ice sheet.
