Abstract
Cartographic data and satellite images have revealed that the area of the Livingston ice cap decreased by 4.31% from 1956 to 1996. Local factors, mainly topographic, have an influence on advances and retreats of the ice front. We established a simple model which correlates the reduction of the ice cap and the atmospheric wa rming detected in the Antarctic Peninsula during the last few decades.
