Some information from this site:

Ice on Greenland and Antarctica is already thinning faster than it's being replaced - and faster than scientists thought it would, notes Richard Alley, a paleoclimatologist at Penn State University and member of one of the research teams. Only five years ago, he notes, climate scientists expected the ice sheets to gain mass through 2100, then begin to melt. "We're now 100 years ahead of schedule," he says.
Has the ocean water levels increased even slightly so far?
If not, then there may be another reason why the polar ice is disappearing.
Since that (other) effect has not been studied at all, it seems to me that the scientists may be barking up the wrong tree so to speak.
It is as if they smell smoke and blame the burning candle, without realizing that the house is on fire.
