25 lut 2022 · Sea ice is essential habitat for polar bears—but across the Arctic, it is disappearing quickly. As a result of rising temperatures caused by the climate crisis, sea-ice concentrations in the Arctic have declined in every decade since the start of satellite records in 1979.
Why do polar bears need sea ice? Polar bears rely heavily on sea ice for traveling, hunting, resting, mating and, in some areas, maternal dens. But they are losing their sea ice habitat because of a warming climate—the primary threat to polar bears throughout the Arctic.
15 gru 2022 · Climate change makes it harder for polar bears to hunt, mate and breed. Image: Unsplash/noaa. Climate change is having a clear negative impact on polar bears, say scientists, making it harder for them to hunt, mate and breed. Polar bears live in 19 key regions, all of which have experienced some degree of ice loss.
Majestic creature of the far north, the polar bear is the world’s largest terrestrial carnivore. Its Latin name, Ursus maritimus, means ‘sea bear’: an apt name for this amazing animal, which spends much of its life in, around, or on the water – predominantly on the sea ice.

Sea ice is also an essential habitat for the polar bear’s primary food, ringed seals, as they pup and rest on the ice. Current knowledge shows that polar bears have some capacity to adjust to the warming Arctic, but the loss of sea-ice habitat may be happening too rapidly to allow for adaptation and there are no substitutes on land for the ...
