ABSTRACT
Considerable uncertainty surrounds the impact of human-induced global warming on the amount of snow and ice cover as scientists are not sure how sensitive ice sheets and glaciers are to changes in surface temperatures. However, all agree that sea-and land-based ice will continue to contract over this century and beyond and
that the rate of contraction is likely to accelerate. This has potentially significant repercussions for global sea level rise, particularly over the next several centuries.
