The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
The polar bear is white- or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water.
In the Arctic, the waters of Hudson Bay are ice-free for three weeks longer than they were thirty years ago, affecting polar bears, which prefer to hunt on sea ice. [103] Species that rely on cold weather conditions such as gyrfalcons, and snowy owls that prey on lemmings that use the cold winter to their advantage may be negatively affected ...
An isolated group of polar bears living in southeast Greenland has surprised scientists with its ability to survive in a habitat with relatively little sea ice. Polar bears face existential threat ...
Arctic fox. The Arctic fox (Vulpes lagopus), also known as the white fox, polar fox, or snow fox, is a small species of fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. [1][8][9][10] It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also ...
Due to climate change in the Arctic, this polar region is expected to become "profoundly different" by 2050. [1]: 2321 The speed of change is "among the highest in the world", [1]: 2321 with the rate of warming being 3-4 times faster than the global average. [2][3][4][5] This warming has already resulted in the profound Arctic sea ice decline ...
Binky (polar bear) Binky (1975 – July 20, 1995) was a captive male polar bear who lived at the Alaska Zoo in Anchorage. In separate incidents in 1994, Binky mauled two zoo visitors; these events received international news coverage. He was originally orphaned near Cape Beaufort, close to the Chukchi Sea in the Alaska North Slope, and was ...
The basis for this cultural/language preservation effort was a model program that Meegan had written up before Alaska 2000, which he named 'Hope from the Land of the Polar Bear.' The new program gave a route to save the threatened Aleut, Athabaskan, Inupiaq, Tlingit, Tsimshian and Yupik languages. The key, Meegan judged, was a culture-based ...
