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.

Western Antarctic ice sheet collapse has already begun, scientists warn
2014-05-12 18:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The collapse of the Western Antarctica ice sheet is already under way and is unstoppable, two separate teams of scientists said on Monday. The glaciers' retreat is being driven by climate change and is already causing sea-level rise at a much faster rate than scientists had anticipated. The loss of the entire western Antarctica ice sheet could eventually cause up to 4 metres (13ft) of sea-level rise, devastating low-lying and coastal areas around the world. But the researchers said that even...

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
2014-05-12 14:16:00| Climate Ark Climate Change & Global Warming Newsfeed
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...
Antarctic Ice 'Cork' Melting Could Lead to Unstoppable Sea Rise
2014-05-10 09:06:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: If a relatively small chunk of ice currently plugging the edge of an ice sheet in Antarctica were to melt, it could release massive amounts of ice into the ocean that would significantly increase global sea level for the next 10,000 years, according to a new report. The ice plug sits on a ridge beneath the East Antarctic Ice Shelf in a region called the Wilkes Basin that has previously been overlooked in sea level projections, because it has appeared to be stable compared to regions of the West...
