If Greenland were to melt rapidly (2 m per century of sea level rise),
what would be the impact of all the cold melt water?
Have there been attempts to model world climate on the assumption of
rapid ice discharge into the North Atlantic?
I've tried to get a first back of the envelope impression by
calculating the heat required to melt all of Greenland, and come to 1
W/m2 over 50 years, but that's not really that helpful.
(7 m of sea level rise should be about 5 m of water spread over the
whole world, that's 5000 kg/m2, heat of fusion of water is 330 kJ/kg,
and at 1 W/m2 that directly gives 1.67 e9 seconds ...)
