West Antarctica slow-motion, unstoppable melt

Mongabay: Two hundred years from now, the planet could look very different. This week two landmark studies revealed that West Antarctica's ice sheet is in a state of seemingly inevitable collapse linked to climate change. The slow-motion collapse would by itself eventually lead to a rise in global levels of 3.6-4.5 meters (12-15 feet), overrunning many of the world's islands, low-lying areas, and coastal cities. The only silver lining is that scientists conservatively estimate that the collapse could take...

West Antarctica glaciers on path toward major sea-level rise: Studies
2014-05-14 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Melting glaciers in West Antarctica are headed toward "irreversible" collapse, suggesting that rising sea levels this century may be worse than expected, and potentially catastrophic in the longer term, scientists warned yesterday. Two separate papers -- one in Science and the other from NASA and University of California, Irvine, researchers -- reported similar trends on the western swath of the ice sheet. A half-dozen unstable glaciers there have been accelerating their melt in recent decades,...
Ice loss in Antarctica since 1980 interactive

Guardian: More than 4 trillion tonnes of ice from Greenland and Antarctica has melted in the past 20 years and flowed into the oceans, pushing up sea levels. The revelations come from a landmark study that provides by far the best measure to date of the effect climate change is having on the planet's biggest ice sheets

Antarctica Glacier Collapsing, Adding to Sea Level Rise
2014-05-12 20:31:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: A massive glacier system in West Antarctica has started collapsing because of global warming and will contribute to significant worldwide sea-level rise, two teams of scientists warn in a pair of major studies released Monday. Scientists had previously thought the two-mile-thick (3.2 kilometers) glacier system would remain stable for thousands of years, but new research suggests a faster time frame for melting. A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible...
Global Warming: 10-13 Feet Increased Sea Levels Once East Antarctica Melts
2014-05-08 22:49:00| Climate Ark Climate Change & Global Warming Newsfeed
IBT: East Antarctica, largely receiving small attention before, has now become the focus of a study where if it succumbs to global warming and melts could push sea levels to rise by 10-13 feet high, enough to drown coastal cities from Tokyo to Mumbai to New York. The world's fifth-largest continent, Antarctica is divided into two unequal halves. The ice in West Antarctica goes through below sea level up to the ocean floor. The ice on East Antarctica, however, sits on a landmass that is above sea level....
