<div id="ember2933" class=""><p id="ember2934" class="">Two teams of scientists say the long-feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries-long, "unstoppable" process that could raise sea levels by as much as 15 feet.        </p>
<p id="ember2935" class="">"There's been a lot of speculation about the stability of marine ice sheets, and many scientists suspected that this kind of behavior is under way," Ian Joughin, a glaciologist at the University of Washington in Seattle, said in a <a href="http://www.washington.edu/news/2014/05/12/west-antarctic-ice-sheet-collapse-is-under-way/">news release</a> about one of the studies published Monday. "This study provides a more qualitative idea of the rates at which the collapse could take place."</p>
