Antarctic glaciers slipping faster into the sea
415582
Antarctic glaciers are thinning and slipping ever faster into the sea, according to several new studies. Warmer air and sea temperatures are blamed, and the changes are expected to cause an appreciable rise in sea levels.

The glaciers in West Antarctica have substantially increased their rate of shrinkage compared with the 1990s. US-Chilean teams report to the journal Science that the glaciers are losing 60% more ice into the

As early as the 1970s, several theorists and climate modelers predicted that global warming would cause ice shelves in the oceans around Antarctica to melt and release glaciers.

Some of Antarctica's glaciers have accelerated their seaward march, suggesting that ocean levels might be irreversibly on the rise for centuries to come.
