Their paper, "Influence of a West Antarctic mantle plume on ice sheet basal conditions," was published in the Journal of Geophysical Research: Solid Earth. Provided by: NASA /JPL. Featured image: Illustration of flowing water under the Antarctic ice sheet. Blue dots indicate lakes, lines show rivers.
So they have analyzed a model of a single ice sheet's evolution over time based on one factor only, and a statistical analysis of "a large number of simulations of the future evolution of a West Antarctic glacier using a state-of-the-art numerical ice sheet model with many thousands of evolving quantities." Something that has never been done ... Jun 17, 2018 · The loss of ice on one side of the world tends to make seas rise on the other side, due to gravity. As mass from the Antarctic ice sheet is lost, gravity in that region decreases, which means that places furthest from that ice sheet tend to see the biggest increases in sea level.

According to a recent report by the Jet Propulsion Laboratory (JPL) at NASA, an enormous cavity two-thirds the area of Manhattan and almost 1,000 feet (300 meters tall) has been growing at the base of Thwaites Glacier in West Antarctica over the span of just a few years. West Antarctic Glacier Loss Appears Unstoppable . A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea. 4 a collapse of the West Antarctic Ice Sheet (WAIS) on the surface climate of 5 Antarctica. The lowered topography following WAIS collapse produces anomalous 6 cyclonic circulation with increased ow of warm, maritime air towards the 7 South Pole, and cold-air advection from the East Antarctic plateau towards The findings suggest that “in only the case of future mild (to moderate) climate change, our finding is a good news for the West Antarctic Ice Sheet”, Barletta says. However, “in the case of extreme climate change, any help to the ice sheet [in preventing eventual collapse] will be useless”, she adds: “I hope the message is clear.
A new study by Rignot and others finds the rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area ...Glaciers in Antarctica's most rapidly warming region have quickened their pace following the collapse of a Delaware-sized ice shelf in March 2002, according to a new study led by the University of ... It describes this: A new radar study shows that the ice sheet feeding the Ross Ice Streams is growing. And here's what Ian Joughin, the author of the study, said (quoted in the article): two nearby West Antarctic glaciers are thinning rapidly, so the trend cannot be extended across the continent. While further ice-sheet destabilisation in other parts of the continent may be limited by a reduction of greenhouse gas emissions, the slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilised. A collapse might take hundreds of years but will raise sea levels worldwide by more than three meters.
