This handout photo provided by NSIDC, University of Colorado, taken in Oct. 2003, shows the icebreaker Aurora Australis awaiting the return of the scientific teams and their equipment in the Antarctic. 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/NSIDC, University of Colorado)
