Antarctica & Greenland Losing Ice at Fastest Rate Ever Recorded
2014-08-21 18:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment 360: Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per year enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick according to German researchers. Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing...
Microbes thrive below Antarctic ice

Christian Science Monitor: Researchers have uncovered a thriving community of microbes in a lake some 2,600 feet below the surface of the West Antarctic Ice Sheet, the first direct evidence of life in such lakes and the first window on the ecosystem the microbes occupy. Genetic evidence extracted from samples of lake water indicates that the lake teems with a wide variety of microbes that make up a complete food chain, with those at the bottom drawing their energy from chemicals in rocks and sediment in the lake bed. In...

Scientists See Record Decline In Greenland And Antarctic Ice Sheets
2014-08-21 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Data from the European Space Agency`s (ESA) CryoSat-2 spacecraft has been used to map elevation and elevation changes in both Greenland and Antarctica by a team of researchers from the Alfred Wegener Institute (AWI) in Germany. The new maps, which are the most complete to ever be created from a single satellite mission, reveal the ice sheets are losing volume at an unprecedented yearly rate (approximately 500 cubic kilometers). The study findings and maps were recently published in The Cryosphere....

Landmark Expedition Discovers Microbial Life Beneath West Antarctic Ice Sheet
2014-08-21 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: An international team of biologists has discovered living microbes and an active ecosystem located one-half mile beneath the surface of the West Antarctic Ice Sheet, according to new research published online Wednesday in the journal Nature. The study, which was funded by the National Science Foundation (NSF) and led by Montana State University professor John Priscu, collected samples from subglacial Lake Whillans, which is located beneath more than 2600 feet of ice and has not been exposed to...
