Greenland and Arctic Circle / Re: Greenland 2018 melt season
« on: June 25, 2018, 06:15:14 PM »
There are already places much further north where there is no snow or ice at this moment. And if the hot blob in the Atlantic becomes permanent. Than why should we not get a little sea in Greenland ? Juan C posted the pic a couple months ago.

Note that this is the current basal topography. Greenland will endure post glacial rebound as the ice sheet melts. For each km of ice, expect the topography to raise by about 300m - 400m (effectively you replace the mass of the ice removed by the same mass of rock, it depends on the density of the rock). The thickest parts of ice sheet are about 3km, so one would expect around a km of uplift.

I'd imagine the ice cut valleys and lakes will be spectacular, but there is unlikely to be a sea.
