It holds enough water to raise sea levels 50 metres, but East Antarctica ice sheet is even more unstable than we thought http://apocadocs.com/s.pl?1377831826
Declassified images from spy satellites going back 50 years have revealed that the coastal glaciers and floating sea ice of Antarctica are more susceptible to air and sea temperatures than previously supposed, the researchers found.
The images, which cover thousands of miles of East Antarctic's coastline and include measurements of 175 glaciers, show there is rapid and synchronised melting and freezing when local temperatures increase or fall, according to the study published in Nature....
"It was a big surprise therefore to see rapid and synchronous changes in advance and retreat, but it made perfect sense when we looked at the climate and sea-ice data. When it was warm and the sea-ice decreased, most glaciers retreated, but when it was cooler and the sea ice increased, the glaciers advanced," Dr Stokes said
