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.
Polar bears have been trained to perform in circuses. Bears in general, being large, powerful, easy to train and human-like in form, were widespread in circuses, and the white coat of polar bears made them particularly attractive. Circuses helped change the polar bear's image from a fearsome monster to something more comical.
Seals are another marine mammal that are susceptible to climate change. [114] Much like polar bears, some seal species have evolved to rely on sea ice. They use the ice platforms for breeding and raising young seal pups.
As climate change diminishes sea ice from coastal communities in the Arctic and the subarctic, researchers expect polar bears to range farther into the towns
Projected change in polar bear habitat from 2001–2010 to 2041–2050. Arctic warming negatively affects the foraging and breeding ecology of native Arctic mammals, such as Arctic foxes or Arctic reindeer. [91] In July 2019, 200 Svalbard reindeer were found starved to death apparently due to low precipitation related to climate change. [92]
