It could do, even within that time frame.... that is a pretty complex issue and very uncertain - different computer models give different results. The feedback effects in the global climate over longer time spans are not well understood.

Warming initially melts glaciers but also increases snowfall in the coastal areas of Greenland and Antarctica as more water evaporates. So mainly the mountain glaciers go, but initially the impact could be a thickening of the two big ice sheets. Higher temperatures also expand the size of the ocean due to simple thermal expansion. Deep water heats up slowly though. So the net effect is expected to be fairly small over the next century.
