It's probably easier to move uphill when the house can be disassembled and packed on a sledge or wagon(s). The little woman probably still complained though.

I can't see a problem about a 20 foot increase in sea levels, if the Dutch can cope with it I'm sure other countries can do the same, also a lot more land would become habitable in Canada and Russia.

I am copying previous comments. polarportal.dk/en/greenland/surface-conditions/
This is the DMI Greenland Mass Balance website. Recently it has been showing rapidly increasing run-off from the ice-sheet.
As part of the site, it shows weather conditions at a selection of locations all around Greenland [click on small dark bulls-eyes].
Looking at those sites, I could only find one which showed a temperature [slightly] above freezing. Not, in my amateur view, enough to cause any significant melting.
So, where cometh the melting?
The point is that most of the Greenland Ice Sheet is still well below freezing.
Even with full Summer insolation, at best the Sun might melt a few centimtres of snow, which would almost immediately refreeze as it hit much colder ice below the surface.
There might be some ice loss from evaporation [sublimation], but I can't imagine that process removing gigatons.
So, I think my question remains unanswered.I am not convinced about the "geothermal heat" argument. Iceland may have heaps, but it is part of the mid-Atlantic rift, where the tectonic plates are ripping apart. I don't recall any active volcanoes in Greenland!

Doug, you are correct moving 10Km away from a volcanic zone can see the temperatures fall dramatically at the surface.
Recently as part of my reeducation for past sins in the oil industry and also to harvest various green subsidies I have been working with some colleagues on geothermal and it's not how you think generally.
A volcano can melt ice but just look at the volcano that came through a glacier in Iceland recently both had been quite close to each other for centuries.
I don't support the narrative that climate could be influenced by energy flux from within.

" Greenland is an island nation in North America ..... " I never knew that ....

the discussion of what a continent is is not alien to Australia.
Are we an island or a continent? But what flows from there is the very definition of a continent?
The rift mid the Atlantic at that, runs between where, and the side upon which Greenland sits is then claimed as its.

Greenland is not a nation. It IS ... emerging from the primordial slime coating the foundation layers of NYC. It's Dante's second passage to Hell.

From Wikipedia:
“The island, three times the size of Texas, has vast natural resources, including uranium, rare-earth minerals, and estimated 50 billion barrels of offshore oil and gas. Greenland has only one operating mine and little infrastructure.”
The U.S. has always had and maintains an important strategic interest in Greenland. I think Denmark likes it that way rather than having the U.S. purchase it.

Greenland ice sheet appears to be growing.
