From today's BBC News: Antarctic shelf 'hangs by thread'. "A chunk of ice the size of the Isle of Man has started to break away from Antarctica in what scientists say is further evidence of a warming climate." and "Professor David Vaughan of BAS said 'I didn't expect to see things happen this quickly. The ice shelf is hanging by a thread - we'll know in the next few days or weeks what its fate will be.'"
