Fifteen years after polar bears were listed as threatened, a new study says researchers have overcome a roadblock in the Endangered Species Act that prevented the federal government from ...
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.
Tools such as bear spray and ‘bear-dar’ deployed to help communities as climate change brings more contact with world’s largest land carnivores. Conservationists working to tackle rising ...
Polar bears are one of the most majestic, yet fearsome animals on the planet. The largest living species of bear and the largest land carnivore, the polar bear is closely related to the brown bear.
The rationale is that bears, being unable to reach the food, are less drawn to campsites and pose less of a threat to campers and their equipment. Often this is done by tying another length of rope tightly between two trees or other tall objects. A bear bag should be at least 15 feet (4.5 m) high and 10 feet (3 m) from any vertical support.
Climate change causes sea ice to melt, transforming the Arctic from an icy desert into an open ocean. Polar bears and seals may lose their habitats, phytoplankton growth may increase and fuel the Arctic food web, which may lead to higher carbon burial rates and possibly decrease the amount of CO 2 in the atmosphere.

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 ...
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).
