An Antarctic ice shelf bigger than Connecticut risks collapse because of global warming after a retreat that began on Feb. 28, the British Antarctic Survey said.
The Wilkins ice shelf, which lost 1,000 square kilometers (390 square miles) of ice, or about 6 percent of its surface, in 1998, calved another 570 square kilometers since February, the survey group said in an e-mailed statement. Now, there's little to stop the loss of another several thousand square kilometers.
