With sea ice breaking up and retreating earlier in the summer, many polar bears have no or minimal access to food during the warmer months, which affects both their physical and reproductive health.Īccording to the new study, an isolated polar bear population on the southeast Greenland coast supplements the low-ice season by relying on glacier ice for hunting when the sea ice is gone. ![]() This is bad news for species that rely on sea ice, like polar bears, that are now being forced to spend more time on land and fast for longer periods of time. It has lost an average of 27,000 square miles of ice per year since 1979. While the sea ice in the Arctic Ocean used to regain the mass it lost in summer during the cold, dark winter months, it has been steadily declining for decades. Typically, polar bears wait by holes in the sea ice for their prey to surface for air so they can snatch them out of the water. Polar bears use sea ice to cross long distances and hunt for ringed seals, their preferred prey, or other seals and marine mammals. This area and the adjacent seas around it provide a critical, shrinking habitat for polar bears. The Arctic Ocean is a mix of liquid and frozen seawater at the North Pole. ![]() Most polar bears rely on sea ice for hunting, and climate change is threatening this vital habitat. The population is isolated and genetically distinct from other groups of polar bears and survives in fjords that are free of sea ice more than two-thirds of the year.Ī typical image of a polar bear on a sheet of melting sea ice in the Arctic. The discovery was published in June in the journal Science by an international team of Arctic scientists. 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. While every population of polar bears is threatened by the loss of this sea ice, some have developed adaptations to survive low-ice seasons. 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. Crayola has my favorite colors because their crayons, paints, and markers color so smoothly on any kind of paper.Īttribution: Many CWF images are licensed at in sea ice provide the perfect hunting ground for polar bears looking to catch their main food source-seals.
