I haven’t seen anything about this in the U.S. Press, though maybe I’ve just missed it, so I’ll pass it along just to spread a little cheer. According to the Independent, there is some new ocean front property available in Greenland:
The map of Greenland will have to be redrawn. A new island has appeared off its coast, suddenly separated from the mainland by the melting of Greenland’s enormous ice sheet, a development that is being seen as the most alarming sign of global warming.
Several miles long, the island was once thought to be the tip of a peninsula halfway up Greenland’s remote east coast but a glacier joining it to the mainland has melted away completely, leaving it surrounded by sea.
Shaped like a three-fingered hand some 400 miles north of the Arctic Circle, it has been discovered by a veteran American explorer and Greenland expert, Dennis Schmitt, who has named it Warming Island (Or Uunartoq Qeqertoq in Inuit, the Eskimo language, that he speaks fluently).
The US Geological Survey has confirmed its existence with satellite photos, that show it as an integral part of the Greenland coast in 1985, but linked by only a small ice bridge in 2002, and completely separate by the summer of 2005. It is now a striking island of high peaks and rugged rocky slopes plunging steeply to a sea dotted with icebergs.
…
But it is only one more example of the disintegration of the Greenland Ice Sheet, that scientists have begun to realise, only very recently, is proceeding far more rapidly than anyone thought.
The second-largest ice sheet in the world (after Antarctica), if its entire 2.5 million cubic kilometres of ice were to melt, it would lead to a global sea level rise of 7.2 metres, or more than 23 feet.
That would inundate most of the world’s coastal cities, including London, swamp vast areas of heavily-populated low-lying land in countries such as Bangladesh, and remove several island countries such as the Maldives from the face of the Earth. However, even a rise one tenth as great would have devastating consequences.
…
Until two or three years ago, it was thought that the break-up of the ice sheet might take 1,000 years or more but a series of studies and alarming observations since 2004 have shown the disintegration is accelerating and, as a consequence, sea level rise may be much quicker than anticipated.
…
A study last year by the Jet Propulsion Laboratory of the California Institute of Technology showed that, rather than just melting relatively slowly, the ice sheet is showing all the signs of a mechanical break-up as glaciers slip ever faster into the ocean, aided by the “lubricant” of meltwater forming at their base. As the meltwater seeps down it lubricates the bases of the “outlet” glaciers of the ice sheet, causing them to slip down surrounding valleys towards the sea,
The latter process, if I recall correctly, was described by Al Gore in “An Inconvenient Truth”.
