Scientists confirm that warm ocean water is melting the biggest glacier in East Antarctica

The Antarctic now seems to be in danger of melting as fast as the Arctic has. The Washington Post has a report on troubling findings from the world's largest ice sheet - Scientists confirm that warm ocean water is melting the biggest glacier in East Antarctica.
Scientists at institutions in the United States and Australia on Friday published a set of unprecedented ocean observations near the largest glacier of the largest ice sheet in the world: Totten glacier, East Antarctica. And the result was a troubling confirmation of what scientists already feared — Totten is melting from below. ...These waters, the paper asserts, are causing the ice shelf to lose between 63 and 80 billion tons of its mass to the ocean per year, and to lose about 10 meters (32 feet) of thickness annually, a reduction that has been previously noted based on satellite measurements.
This matters because more of East Antarctica flows out towards the sea through the Totten glacier region than for any other glacier in the entirety of the East Antarctic ice sheet. Its entire “catchment,” or the region of ice that slowly flows outward through Totten glacier and its ice shelf, is larger than California. If all of this ice were to end up in the ocean somehow, seas would raise by about 11.5 feet.
