Does the icecap move

Answer 1

Both the Arctic polar ice cap and the Antarctic ice sheets are constantly moving: they grow in the winter (in their respective poles) and shrink in the summer. Pieces of them can break off and turn into ice floes, or the much larger icebergs and ice sheets.

A majority of scientists believe that the recent trend towards global warming is shrinking the ice at both poles faster than they can regenerate. Some scientific models have the Arctic ice disappearing completely as soon as 2050; this can have catastrophic global consequences, as the additional melt water will disrupt both the oceans' salinity levels, and certain critical ocean currents (such as the Gulf Stream, which brings unseasonably mild weather to the UK, which otherwise is on the same latitude as the Canadian province of Newfoundland and Labrador). Answer previously given is perfectly correct, but if you mean "moving" as in the drift of continents, the answer is no; ice caps are climatic phenomenons still under study right now. What we know is that they shrink, disappear, come back, expand, thicken, melt, already many times all through the history of our planet. What is in fact moving is the magnetic poles of the Earth, which even reversed many times in past history of our planet and will surely still do.
