Ice Shelf Breakup Causes Antarctic Glacier to Melt Faster; Sea Levels at Risk
The recent breakup of an Antarctic ice shelf is speeding up the ocean-bound descent of a glacier holding back at least a meter of sea level rise, Ice front of the ice shelf in front of Pine Island Glacier, a major glacier system of West Antarctica."The real question is, how fast is that going to happen, and how much time do we have to adapt?" said Pierre Dutrieux, an oceanographer at the British Antarctic Survey and a co-author of the study. When ice from the ice sheet enters the ocean, it raises sea levels, which will eventually make coastal cities unlivable.The worrying activity prompted researchers at the University of Washington and British Antarctic Survey to study the reasons behind the glacier's accelerated movement. They shared their results June 11 in…
