The edge of Kongsbreen glacial bay is pictured on Feb. 26, 2008 as Kongsbreen, the most active calving glacier in Svalbard, has receded by about 4.5 km in 30 years. For the third winter running, the fjord is not frozen over due to warmer water on the surface, a warning sign of global warming. (Hakon Mosvold Larsen/AFP/Getty Images)
