Refreezing Water Causes Weird Warps in Greenlands Ice
2014-06-15 19:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The flat, glistening, white expanse of the Greenland Ice Sheet, stretching out across hundreds of thousands of square miles, appears placid, unchanging ... boring even. But this tranquil surface belies the turmoil taking place below, at the base of the ice sheet. There, scientists have discovered sections of ice up to a kilometer thick and tens of kilometers long where meltwater has refrozen to the base of the ice sheet, setting off a dynamic process that causes the layers of ice to build up over...
Dust Particles Are Speeding Up the Melting of Greenland's Ice Shelf

Softpedia: In a paper recently published in the journal Nature Geoscience, a team of researchers argue that, according to evidence at hand, Greenland's ice shelf has high chances to get a whole lot smaller way sooner than anyone would expect. Since the melting of this massive block of ice is expected to translate into a noteworthy increase in global sea levels, specialists warn that, the faster it melts, the sooner and the worse coastal communities could be affected by this phenomenon. What's interesting...

Dust in the Wind Could Speed Greenlands Ice Melt
2014-06-08 19:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Despite it's name, Greenland is predominantly white, as snow and ice cover the majority of the country. New research indicates that Greenland's main color may be starting to fade and in fact darken, though, thanks to a widespread increase of dust across the ice sheets. That darkening could speed up surface melt, and with it, sea level rise around the globe. More than three-quarters of Greenland is covered by a massive ice sheet that's up to 2 miles thick in spots. It contained 684,000 cubic miles...
Greenlands ice sheet melting faster than previously believed

Copenhagen Post: The ice sheet in northern Greenland is melting and moving into the ocean thereby adding billions of tonnes of melting water to the worlds already rising ocean levels. Researchers from Denmarks Technical University (DTU), the University of Copenhagen and Aarhus University have documented that the outlet glacier in northeast Greenland, stretching from the inland ice sheet to the sea, has been moving towards the sea since 2006. Its very surprising that the northeast outlet glacier is moving. We...

Natural Variations May Account for Up to Half of Greenland's Warming
2014-05-08 18:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Up to half of the recent climate change in Greenland and surrounding regions which have warmed at roughly twice the pace of the rest of the planet since 1979 may be due to natural climate variations that originate in the tropical Pacific and are not connected with the overall warming of the Earth, a new study says. Still, at least half the warming remains attributable to rising global carbon dioxide emissions, according to research published in the journal Nature. Climate data and advanced computer...
