- The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. A boar (adult male) weighs around , while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means “maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals. Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect. For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures. Historically, the polar bear has also been known as the "white bear". It is sometimes referred to as the "nanook", based on the Inuit term nanuq.

- QUOTE: ... The prediction that the polar bear would suffer immensely because of a lack of summer ice was always somewhat odd. Polar bears survived through the last interglacial period 130,000 to 115,000 years ago, when it was significantly warmer than it is now. They also survived the first thousands of years of the current interglacial period, when arctic sea ice cover was strongly reduced and there were even long periods of ice-free summers in the central Arctic Ocean.2 ...
... The real threat to polar bears isn’t climate change, it’s people. Every year around the Arctic, hunters kill almost nine hundred of them. That’s more than three polar bears out of every one hundred that exist, every year. If we want to protect them, rather than dramatically reducing carbon emissions to try to tweak temperatures over many decades with a clearly uncertain impact on polar bear populations, our first step should be to stop shooting them. In fact, when it comes to species extinction, of both fauna and flora, human behavior is a much larger factor than climate change. ...
