Antarctica's "Doomsday Glacier" Headed for Collapse, Portending Disastrous Sea Level Rise
-----------------------------------------------------------------------------------------

A team of researchers reports Antarctica's enormous Thwaites Glacier is
on the verge of collapse, with warm water seeping under the weakest
parts of the glacier and melting it from below. Researchers deployed a
robotic submarine to penetrate the vast ice sheet, which is roughly the
size of Florida. They found the glacier is susceptible to rapid and
irreversible ice loss that could raise global sea levels by more than
half a meter. Its collapse could destabilize surrounding glaciers that
could raise the Earth's oceans by a further three meters - or nearly 10
feet.
