Scientists explore Thwaites, Antarctica’s ‘doomsday’ glacier

A team of scientists is sailing to “the place in the world that’s the hardest to get to” so they can better figure out how much and how fast seas will rise because of global warming eating away at Antarctica’s ice. Thirty-two scientists on Thursday are starting a more than two-month mission aboard an American research ship to investigate the crucial area where the massive but melting Thwaites glacier faces the Amundsen Sea and may eventually lose large amounts of ice because of warm water. “Thwaites is the main reason I would say that we have so large an uncertainty in the projections of future sea level rise and that is because it’s a very remote area, difficult to reach,” Anna Wahlin, an oceanographer from the University of Gothenburg in Sweden, said Wednesday in an interview from the Research Vessel Nathaniel B. Palmer, which was scheduled to leave its port in Chile hours later. The British Antarctic Survey says the glacier is responsible for 4% of global sea rise, and the conditions leading to it to lose more ice are accelerating, University of Colorado ice scientist Ted Scambos said from the McMurdo land station last month. Oregon State University ice scientist Erin Pettit said Thwaites appears to be collapsing in three ways: — Melting from below by ocean water.
