What temperature do polar bears need?
Thanks to special adaptations, such as a thick layer of blubber, two layers of fur, compact ears, and a small tail, polar bears can withstand temperatures as low as -50° Fahrenheit.
Polar bears are excellent swimmers, but their preferred habitat is on top of the ice that covers Arctic seas much of the year. That is where they mate, hunt and rear their young. Sea ice is vital to polar bears.
“Even in Alaska and northern Canada, the temperature can get up to the 80s in the summer. So they're adapted to not only the really cold environment and icy cold water, but they do OK in warmer summer conditions.”
No, a polar bear will not be comfortable in a hot place because it has fur and a thick layer of fat under its skin that protects it from the of the polar region. If we took it to a hot region this body adaptation will make it very hot and it will not survive.
Polar bears overheat—a lot
You would think that in their icy, arctic environment, polar bears spend most of their time shivering with cold! However, polar bears struggle more with overheating than they do fending off sub-zero temperatures.
Polar bears (Ursus maritimus) typically need sea ice to survive, so the discovery is raising hopes that some members of the species might survive the loss of ice caused by climate change.
They are toasty warm and comfortable in the frigid arctic. Their heat insulation is in several layers. Under their skin, there is a 4-inch (21.5 cm) layer of fat. Next to the skin is a dense layer of woolly fur that also keeps heat in.
Bears, a small group of mostly large omnivorous mammals, can be found all over the world; they live in forests, mountains, tundra, deserts and grassy areas.
Polar bears will not be able to surmount the impacts of global warming on their Arctic habitat, according to scientists, because they will not be able to adjust their metabolism to survive on land-based prey during longer and longer periods with no sea ice.
However, grizzly bears are tougher than polar bears as they possess stronger and longer claws and an elongated skull with sharp and long canines that can completely separate the flesh from bone.
Can a polar bear live in Florida?
The black bear is the only bear species present in Florida. There are no grizzlies, brown bears, or polar bears in the state.

Polar Bears need the colder weather too for them to be comfortable. When you see them in the Arctic weather you may feel sorry for them. However, there is no need to because they become too warm when their bodies reach only 50 degrees Fahrenheit.
Polar bears are very adaptable to a wide range of air temperature. They can experience temperatures up to 80 degrees in their arctic habitat. Unlike other bears that can hibernate during winter, polar bears are most active during the coldest part of the year.
The warmest areas in summer are inland regions of Siberia, Alaska, and Canada where temperatures can reach as high as 32°C (90°F).

The hair on the pads of their feet stops them from slipping on the ice. They can curl their thick bushy tails around their nose and face to keep them warm. In winter the white fur acts as camouflage to help hide them from their prey.
Polar bears are considered to be vulnerable to extinction, largely due to the rapid decline of sea ice brought on by climate change. One study has suggested that most polar bears could disappear by 2100 if the world continues to rapidly warm.
The skin under the polar bear's fur is actually black; this black is evident only on the nose. Polar bears also have a thick layer of fat below the surface of the skin, which acts as insulation on the body to trap heat.
As well as reaching speeds of up to 6mph in the water, polar bears can swim for long distances and steadily for many hours to get from one piece of ice to another. Their large paws are specially adapted for swimming, which they'll use to paddle through the water while holding their hind legs flat like a rudder.
It would be extremely reckless to try to introduce polar bears into the Antarctic in order to save them from extinction. The Antarctic species that the bears would be likely to prey upon have evolved no defences to polar bear predation and would be likely to suffer catastrophic losses.
What would happen if you put a polar bear in the Antarctic?
If polar bears were introduced to the Antarctic, penguins would be like lame ducks for the polar bears to feast upon. With these known advantages, the polar bear stands to overindulge on Antarctic prey, which could lead to devastating consequences for Antarctica's long-term residents.
Except for one subspecies of grizzly bear, the polar bear is the largest and most powerful carnivore on land. It has no natural predators and knows no fear of humans, making it an extremely dangerous animal.
Polar bears live in the Arctic, but not Antarctica. Down south in Antarctica you'll find penguins, seals, whales and all kinds of seabirds, but never polar bears. Even though the north and south polar regions both have lots of snow and ice, polar bears stick to the north.
Polar bears can survive in the most harshest tundras but do you know that it can't survive in the desert because a polar bear is hardwired to have a lot of fur and it would probably die of dehydration.
Bears also dislike the strong scent of pine-based cleaners, but avoid using anything with a fresh, lemony or fruity smell. And never mix bleach and ammonia; the combination produces fumes that can be deadly to both people and bears.
