24 surveys suggest that ice in Antarctica is melting now triple the rate it was 5 years ago

These days, however, scientists studying ice movement on the Antarctic are inundated by measurements—so much so that today, a group of scientists has published the combined results of 24 different surveys of Antarctic ice loss in an edition of Nature. Together, they suggest that the rate of melting has tripled in the past five years. Led by investigators Andrew Shepherd of the University of Leeds and Erik Ivins of NASA, they believe that the loss, now up to 219 billion metric tons per year, is driven both by faster-flowing ice streams and by warmer ocean waves lapping at the bottom of ice shelves.
