In glaciology, starvation occurs when a glacier retreats, not because of temperature increases, but due to precipitation so low that the ice flow downward into the zone of ablation exceeds the replenishment from snowfall. Eventually, the ice will move so far down that it either calves into the ocean or melts.
When starvation does occur, however, it can almost always be reversed by slight changes in precipitation, such as are brought about by mountain ranges. Thus, even if glaciers do not cover a lowland due to low precipitation, glaciation is almost certain to occur at higher elevations.
Famous quotes containing the word starvation:
“If in this wide world, teeming with abundant supplies for human want, to thousands of wretched creatures no choice is open, save between starvation and sin, may we not justly say that there is something utterly wrong in the system that permits such things to be?”
—Tennessee Claflin (18461923)
