Tectonic subsidence
I reverted your edit as questions like that should not be added to an article. However, to answer your specific question, take a look at post-glacial rebound. Areas such as the Gulf of Bothnia are currently rebounding following the melting of the ice sheet that used to cover the area. So quite the reverse, Greenland will actually rebound rather than subside if the icesheet does actually melt. Mikenorton (talk) 17:57, 20 March 2019 (UTC)
