Yes. The Arctic sea ice, their habitat, the only place they can hunt seals, is decreasing every year from global warming. Bears are weakened from hunger and female bears are having fewer cubs.
Some local populations are on the decline, and some are increasing slightly. The overall population is currently fairly stable at 20-25000.
There are 19 polar bear populations there.
Polar bear populations are threatened by changing weather patterns, and by poachers.The return of sea ice to their habitat will help, but poaching remains a problem. There are more polar bears today, however, than thirty years ago, nearly three times the number. Source: IUCN Redlist
As of now, the polar bear is a vulnerable species, not on the endangered species list, as some populations are increasing.

The polar bear isn't currently going extinct anywhere. There are several populations, and some are doing better than others, but as of this time none of the populations are in extreme danger.
Decreasing
Right now, polar bears depend on humans. The habitat of the polar bear is decreasing. Because of global warming, the ice is melting. Polar bears are dying off because they have to swim long distances to get to ice.
Because the polar bear has been used as a proxy to promote the threat of global warming. Polar bear populations are not actually declining - the species is threatened only if you assume that hysterical predictions of warming are true.
The polar bear has not been listed as an endangered species, some populations are in decline, while others are doing well. Listed as vulnerable.
why does the polar bear helps the polar ice
The grizzly or brown bear and the polar bear are basicly the same size.
