Polar bear. The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as ...
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.

[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 ...
Polar bear plunge. Participants in the water during a polar bear plunge when there is ice on the water. A polar bear plunge is an event held during the winter where participants enter a body of water despite the low temperature. In the United States, polar bear plunges are usually held to raise money for a charitable organization. In Canada ...
Average summer temperatures on Svalbard range from 3 to 7 °C (37.4 to 44.6 °F) in July, and winter temperatures from −13 to −20 °C (8.6 to −4.0 °F) in January. [8] The highest temperature ever recorded was 23.0 °C (73.4 °F) in July 2020 [9] and the coldest was −46.3 °C (−51.3 °F) in March 1986. The archipelago is the meeting ...
The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter ...
Ice cap climate. An ice cap climate is a polar climate where no mean monthly temperature exceeds 0 °C (32 °F). The climate generally covers areas at high altitudes and polar regions (60–90° north and south latitude), such as Antarctica and some of the northernmost islands of Canada and Russia. Most of Greenland is under the influence of an ...
