The Greenland Ice Sheet: Now in HD

The Greenland Ice Sheet: Now in HD
San Francisco CA (SPX) Dec 19, 2014 - The Greenland Ice Sheet is ready for its close-up. The highest-resolution satellite images ever taken of that region are making their debut. And while each individual pixel represents only one moment in time, taken together they show the ice sheet as a kind of living body--flowing, crumbling and melting out to sea. The Ohio State University has partnered with the Polar Geospatial Center at ... morehttp://www.spacedaily.com/reports/The_Greenland_Ice_Sheet_Now_in_HD_999.html

Hidden Movements of Greenland Ice Sheet, Runoff Revealed
Greenbelt MD (SPX) Dec 19, 2014 - For years NASA has tracked changes in the massive Greenland Ice Sheet. This week scientists using NASA data released the most detailed picture ever of how the ice sheet moves toward the sea and new insights into the hidden plumbing of melt water flowing under the snowy surface. The results of these studies are expected to improve predictions of the future of the entire Greenland ice sheet ... more http://www.spacedaily.com/reports/Hidden_Movements_of_Greenland_Ice_Sheet_Runoff_Revealed_999.html

Migrating 'supraglacial' lakes could trigger future Greenland ice loss
Leeds, UK (SPX) Dec 19, 2014 - Predictions of Greenland ice loss and its impact on rising sea levels may have been greatly underestimated, according to scientists at the University of Leeds. The finding follows a new study, which is published in Nature Climate Change, in which the future distribution of lakes that form on the ice sheet surface from melted snow and ice - called supraglacial lakes - have been simulated fo ... more http://www.spacedaily.com/reports/Migrating_supraglacial_lakes_could_trigger_future_Greenland_ice_loss_999.html

 North Atlantic signalled Ice Age thaw 1,000 years before it happened
London, UK (SPX) Dec 19, 2014 - The Atlantic Ocean at mid-depths may have given out early warning signals - 1,000 years in advance - that the last Ice Age was going to end, scientists report in the journal Paleoceanography. Scientists had previously known that at the end of the last Ice Age, around 14,700 years ago, major changes occurred to the Atlantic Ocean in a period known as the Bolling-Allerod interval. During thi ... morehttp://www.spacedaily.com/reports/North_Atlantic_signalled_Ice_Age_thaw_1000_years_before_it_happened_999.html
