,Holes in sea ice provide the perfect hunting ground for polar bears looking to catch their main food source—seals. So when rising temperatures cause sea ice to melt, polar bears’ existence is threatened, making them the poster species for many climate change reports and documentaries. While every population of polar bears is threatened by the loss of this sea ice, some have developed adaptations to survive low-ice seasons. In southeast Greenland, researchers have discovered a unique subpopulation of polar bears that have found a way to live in an area with low sea ice by hunting on glacial mélange—a floating mixture of icebergs that have calved from glaciers, sea ice, and snow that forms at the base of glaciers and survives the warm season.
