About 81% of its surface is covered by ice, known as the Greenland ice sheet, the weight of which has depressed the central land area to form a basin lying more than 300 metres (984 ft) below the surrounding ocean. Approximately one-twentieth of the world's ice and one-quarter of the earth's surface ice is found in Greenland.

Scientists who probed two kilometers (1.2 miles) through a Greenland glacier to recover the oldest plant DNA on record said Thursday the planet was far warmer hundreds of thousands of years ago than is generally believed. DNA of trees, plants and insects including butterflies and spiders from beneath the southern Greenland glacier was estimated to date to 450,000 to 900,000 years ago, according to the remnants retrieved from this long-vanished boreal forest. That view contrasts sharply with the prevailing one that a lush forest of this kind could only have existed in Greenland as recently as 2.4 million years ago. The existence of those DNA samples suggest the temperature probably reached 10 degrees C (50 degrees Fahrenheit) in the summer and -17 °C (1 °F) in the winter. They also indicated that during the last interglacial period, 116,000–130,000 years ago, when temperatures were on average 5 °C (9 °F) higher than now, the glaciers on Greenland did not completely melt away.

An interest in witnessing an earth changing event is very different from taking joy in the loss of life such an event would have.

I feel the same way about a west coast mega-thrust earthquake, a New Madrid catastrophe, or the collapse of La Palma.
We rarely see geological events of this magnitude and almost never in one particular person's lifetime. We are just a fleeting influence on this world when you look at the grand scheme of things and I hope I get to live in interesting times.

isn't Greenland itself sitting above a 'hot spot', and that's why there's geysers, volcanos all over the place?
I think the standard model is that at a 'hot spot' the molten mantle is closer to the surface of the earth's crust (there's a dome of magma)
and as the crust which is Greenland rises- -so to does the 'hot spot'

If we all spread out, things will improve.
