(Newser) – A huge ice shelf in the western Antarctic has become unstable and is beginning to fracture into icebergs, the Telegraph reports. Images from space show that the Jamaica-sized Wilkins ice shelf has lost 270 square miles of ice in recent weeks. Scientists expect the "fragile and vulnerable" shelf to continue losing ice, and blame the changes on global warming.
