The West Antarctic glaciers are breaking up with us

Grist: Its Monday, and you probably wanted to ease into the week with a post about cute animals or something. Instead, today scientists broke the news that the West Antarctic ice sheet is now in irreversible collapse, meaning a likely 10 to 15 foot global sea-level rise in coming centuries. Before you get cranking on that ark (maybe you can have those cute animals after all!), let`s take a deep breath. Theres still uncertainty about how cataclysmic this particular cataclysm is.

West Antarctic glaciers in "irreversible" thaw, raising seas -study
2014-05-12 15:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Vast glaciers in West Antarctica seem to be locked in an irreversible thaw linked to global warming that may push up sea levels for centuries, scientists said on Monday. Six glaciers, eaten away from below by a warming of sea waters around the frozen continent, were flowing fast into the Amundsen Sea, according to the report based partly on satellite radar measurements from 1992 to 2011. Evidence shows "a large sector of the West Antarctic ice sheet has gone into a state of irreversible retreat",...
Glaciers draining Antarctic basin destabilized, big sea level rise all but certain

Ars Technica: Today, researchers at UC Irvine and the Jet Propulsion Laboratory have announced results indicating that glaciers across a large area of West Antarctica have been destabilized and that there is little that will stop their continuing retreat. These glaciers are all that stand between the ocean and a massive basin of ice that sits below sea level. Should the sea invade this basin, we'd be committed to several meters of sea level rise. Even in the short term, the new findings should increase our...
Nearing collapse? West Antarctica's glaciers speeding up
2014-03-30 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Six big glaciers in West Antarctica are flowing much faster than 40 years ago, a new study finds. The brisk clip may mean this part of Antarctica, which could raise global sea level by 4 feet (1.2 meters) if it completely melts, is nearing full-scale collapse. "This region is out of balance," said Jeremie Mouginot, lead study author and a glaciologist at University of California, Irvine. "We're not seeing anything that could stop the retreat of the grounding line and the acceleration of these...

'Fossilized rivers' reveal clues about disappearing glaciers

LiveScience: An amazing landscape left behind by melting ice sheets offers clues to the future of Greenland's shrinking glaciers, a new study suggests. The incredible terrain is in northern Canada, which is ridged with thousands of eskers -- the sinuous, gravelly remains of streams and rivers that flowed beneath the ice. Canada was once buried beneath miles of ice, similar to the way Greenland is today. Called the Laurentide Ice Sheet, this massive ice cap covered all of Canada and parts of the northern United...
