In fact, another recent study posted in Science, concluded that polar ice sheet melting has been massively overestimated.

FORBES: Man The Lifeboats! Global Warming Has Oceans Rising At Alarming Rate! (Or Maybe not)

This means that we can expect more than the one-meter sea level rise projected for 2100, a fact that the rapid melting of the Greenland ice sheet, as well as strong indications that the western part of the Antarctic ice sheet is also melting, strongly support.

Over the next four days we observe independent scientists working to understand why the ice sheet is melting so rapidly.

CNN: Greenland's frozen landscape warming up

Arctic glaciers including the Greenland ice sheet are melting and disintegrating faster than expected.

ECONOMIST: Climate change

China has been making strenuous actions to buy mines of RE ore around the world, to maintain its dominance of the global markets, and I wonder whether this will extend to Greenland, where the melting ice-sheet is likely to ease access to the rich veins of REs and other elements that the world needs to maintain its technologies and energy supplies.

FORBES: Shortage Of Rare Earth Metals Exacerbated By Smuggling

It would take the melting of an ice sheet to do that.

ECONOMIST: A meltdown tinged with acid

Melting on the ice sheet's surface acts as a feedback mechanism, Dr van den Broeke explained, because the liquid water absorbs more and reflects less of the incoming solar radiation - resulting in a heating of the ice.

BBC: Greenland ice loss 'accelerating'

Greenland's surface layer vaulted into the news in summer 2012 when higher than normal temperatures caused surface melting across about 97 percent of the ice sheet.
