Collapse of Antarctic glaciers seems to be unstoppable

New Scientist: Parts of the West Antarctic Ice Sheet are already collapsing and probably can't be saved. Two independent studies suggest that several glaciers have gone past the point of no return, dooming them to fall into the sea and cause several metres of sea level rise. However the collapse will take centuries. "A large sector of the West Antarctic Ice Sheet has gone into irreversible retreat," says Eric Rignot of the University of California at Irvine, who led one of the studies. "We've gone beyond the...

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...
Releasing cork in Wilkes Basin Antarctica yields unstoppable sea-level rise

Environmental News Network: Potsdam Institute for Climate Impact Research (PIK) latest study shows that if East Antarcticas Wilkes Basins rim of ice lets go, it is likely to trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come. Using the ground profile under the ice, the researchers used computer ice flow simulations under the ice sheet. "East Antarctica's Wilkes Basin is like a bottle on a slant," says lead-author Matthias Mengel, "once uncorked, it...

Melting East Antarctica ice could mean thousands of years of unstoppable sea level rises
2014-05-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Science 2.0: The melting of a rather small ice volume on East Antarctica's shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come, according to computer simulations of the Antarctic ice flow by scientists at the Potsdam Institute for Climate Impact Research (PIK). They detail their estimates in Nature Climate Change. "East Antarctica's Wilkes Basin is like a bottle on a slant," says lead-author Matthias Mengel, "once uncorked, it...
Melting Antarctic Ice May Trigger Unstoppable Sea-Level Rise

Nature World: Yet another melting ice formation in Antarctica may dump so much water into the ocean that it could trigger an unstoppable rise in sea level for thousands of years to come, a new study published in Nature Climate Change revealed. The current region threatening to raise our seas is the Wilkes Basin, the largest region of marine ice on rocky ground in East Antarctica. Currently, only a rim of ice at the coast holds the ice behind in place. "East Antarctica's Wilkes Basin is like a bottle on a...
