I share, of course, the concerns of Richard Alley regarding the future of the Earth glaciers under future global warming (and of the glaciologists' well-being). As mentioned in Gildor [2003] and Tziperman and Gildor [2003], we expect the temperature-precipitation feedback [Le-Treut and Gildor, 1983] to hold up to some limit temperature. Obviously, ice sheets need to have snow fall over them in order to grow. At temperatures in which more and more of the precipitation falls as rain instead of snow, the actual accumulation over continental ice sheets will decrease with increasing temperature.
