Greenlands Icecap Becoming Unstable
2014-04-14 14:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: LONDON-Greenland-the largest terrestrial mass of ice in the northern hemisphere-may be melting a little faster than anyone had guessed. A region of the Greenland ice sheet that had been thought to be stable is undergoing what glaciologists call dynamic thinning. That is because the meltwater from the ice sheet is getting into the sea, according to a study in Nature Climate Change. In short, Greenlands contribution to sea level rise has been under-estimated, and oceanographers may need to think...

Greenland's Jakobshavn Glacier is Moving 10 Miles Per Year, Recording-Breaking Speed
2014-02-03 20:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The massive Arctic glacier believed to be responsible for calving the iceberg that sunk the Titanic is moving from the Greenland ice sheet and into the ocean at record speeds, according to a study in the journal The Cryosphere. Jakobshavn Glacier is moving at a speed that appears the be the fastest ever recorded, researchers from the University of Washington and the German Space Agency (DLR) report. "We are now seeing summer speeds more than four times what they were in the 1990s on a glacier...
Greenland's Jakobshavn Glacier Is Moving at Record Speeds, Study Finds
2014-02-03 19:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Greenland's Jakobshavn Glacier is flowing into the ocean at a record pace of more than 17 kilometers per year, according to research by U.S. and German scientists. The glacier, which drains 6 percent of the massive Greenland ice sheet, moved at a rate of 46 meters per day in the summer of 2012 four times the glacier's 1990s summer pace. The unprecedented speed appears to be the fastest ever recorded for any glacier or ice stream in Greenland or Antarctica, the researchers report in the journal...

Greenland's Snow Hides 100 Billion Tons of Water
2013-12-23 07:21:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Big surprises still hide beneath the frozen surface of snowy Greenland. Despite decades of poking and prodding by scientists, only now has the massive ice island revealed a hidden aquifer. In southeast Greenland, more than 100 billion tons of liquid water soaks a slushy snow layer buried anywhere from 15 to 160 feet (5 to 50 meters) below the surface. This snow aquifer covers more than 27,000 square miles (70,000 square kilometers) -- an area bigger than West Virginia -- researchers report today...
Two Lakes Discovered Under Greenland's Ices
2013-11-28 05:57:00| Climate Ark Climate Change & Global Warming Newsfeed
Softpedia: A team of researchers with the Scott Polar Research Institute (SPRI) from the University of Cambridge announces the discovery of two subglacial lakes in Greenland, the first of their kind to be found on the island. Similar formations were thus far only known to exist beneath the Antarctic ice sheets. According to the research group, these lakes are now only one third of their previous area. Measurements conducted by the team revealed that each of the two lakes covers an area of 8 to 10 square...
