The pace of melting rose dramatically over the four-decade period. From 1979 to 2001, it was an average of 48 gigatonnes annually per decade. The rate jumped 280 per cent to 134 gigatonnes for 2001 to 2017.
During Antarctica's summer, scientists from University of Wisconsin - Milwaukee (UWM) climbed the McIntyre Promontory's frozen slopes in the Transantarctic Mountains, and found evidence of these ancient fossils.
A trillion-tonne iceberg – one of the largest ever recorded - has broken away from Antarctica after many months of anticipation and may now pose a serious hazard to ships around the South Pole, scientists said today. The event occurred sometime between July 10 and July 13.
Antarctica ice sheet breaks off: But while the breaking off of the iceberg is worrisome, experts caution that the glaciers behind it are the bigger problem. The size of the iceberg is lesser of an issue because icebergs, according to scientists, calve all the time and have minimal direct effect on sea level.
The March mission was part of NASA’s Oceans Melting Greenland (OMG) project, a five-year, $30 million effort aimed at improving sea level rise projections by understanding how warming oceans are melting ice sheets from below - the most ambitious research on the subject to date
