It's difficult to get an exact figure for all polar bear numbers but some bears are almost definitely dying because of global warming.
Rising temperatures cause Arctic sea ice to melt earlier in the year, so the bears are driven to go ashore without sufficient fat reserves to survive late summer and early autumn. Reduction of sea ice means they have to swim more, making them weaker. Some drown. Thinner sea ice makes it harder for them to catch seals. Poorly nourished female bears don't build suitable dens, don't produce as many cubs, and cubs that are born have a lower survival rate.
The Western Hudson Bay subpopulation of polar bears are one of the best studied. Warming temperatures mean that ice-floe breakup in western Hudson Bay now happens three weeks earlier than it did 30 years ago, so the bears' feeding season is similarly shortened. The average weight of single female bears was about 290 kg in 1980. In 2004 the average weight was 230 kg. Bear population in Western Hudson Bay declined 22% between 1987 and 2004.

global warming is killing the animals such as polar bears, hibernating animals and much more
They haven't. Polar bears are now a threatened species. If the polar ice cap goes, then so do the polar bears, as they rely on oceanic ice to secure their food.

Global warming is a significant contributing factor to the decline in polar bear populations. As the Arctic sea ice melts due to rising global temperatures, it reduces the bears' hunting grounds and access to important food sources, making it harder for them to survive. This is leading to decreased body condition, lower cub survival rates, and an overall decline in polar bear numbers.
they live in the arctic and are dying out because of global warming!
Polar bears do not cause global warming. In fact, polar bears are affected by global warming due to the shrinking of their sea ice habitat. The loss of sea ice reduces their hunting grounds and threatens their survival.
Global Warming does affect the survival rate of Polar Bears because Global Warming Melts the ice.
Probably not. We have only begun to act to stop global warming, and what the world has done so far is nowhere nearly enough. Polar bears are probably dying already. See the related question below.
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.
people and global warming
Global Warming.
Polar bears are not a cause of global warming. They are being affected by climate change in that their habitat is decreasing in size (as the sea ice is melting).
Arctic ice is melting from global warming. Bears need the ice to catch seals which they rely on for food.
Countries and their citizens are trying to slow and maybe even stop global warming. This is the only thing that will help polar bears.
Because of global warming, you can't hunt polar bears
