This is kind of interesting. It seems to be finding that the mass of the Greenland ice sheet is staying relatively the same in that, even with the melt that is occuring at the lower elevations, there has been a steady net gain in the upper elevations. And some speculation relative to the possibility that there may be something about the warming conditions that cause the lower melt that is the very cause of the net gain in the upper elevations.

And apparently there are elevations in Greenland that are on a par with the American Rockies.
