Polar Bears

A combination of pictures shows an ice-sculpture of a polar bear as it melts to reveal a bronze skeleton in Copenhagen December 14, 2009. The first picture was taken on December 7, the day of the beginning of the UN Climate Change Conference in Copenhagen, the second on December 10 and the third on December 14. The installation is a part of an initiative to put focus on the consequences of global warming.
