East Antarctica's Wilkes Basin is like a bottle on a slant," says lead-author Matthias Mengel, "once uncorked, it empties out." The basin is the largest region of marine ice on rocky ground in East Antarctica. Currently a rim of ice at the coast holds the ice behind in place: like a cork holding back the content of a bottle. While the air over Antarctica remains cold, warming oceans can cause ice loss on the coast. Ice melting could make this relatively small cork disappear -- once lost, this would trigger a long term sea-level rise of 300-400 centimeters. "The full sea-level rise would ultimately be up to 80 times bigger than the initial melting of the ice cork," says co-author Anders Levermann.
"That's it for every beach in the world," Fort said, pulling his face back from the window. Then: "I guess we'd better go get our stuff."
