This handout photo provided by the British Antarctic Survey, taken in March 2003, shows four scientists being retrieved from research on sea ice in the Antarctic using a buoy. The ice goes on seemingly forever in a white pancake-flat landscape, stretching so far it just set a record. And yet in this confounding region of the world, that spreading ice may be a cock-eyed signal of man-made climate change, scientists say. (AP Photo/David Vaughan, Bristish Antarctic Survey)
