Can polar bears move south?
Polar bears are moving further south into communities because they're adopting new hunting practices. If the sea-ice isn't forming, they can't hunt on it. If they can't hunt on the ice, they can't hunt seals, which forces them to look for new food sources.
“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.”
Polar bears live in Alaska, Canada, Russia, Greenland, and some northern islands owned by Norway, such as Svalbard. Polar bears depend on the sea ice, which forms above the open waters where their seal prey lives.
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 farthest south that polar bears live all year round is James Bay in Canada, which is about the same latitude as London, England. During winter, when the polar ice pack extends further south, polar bears move as far south as Newfoundland and into the northern Bering Sea.
While polar bears are excellent swimmers, they would struggle to migrate to Antarctica. As they are adapted to a polar climate, the tropical latitudes would be a little too hot to handle.
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 are not likely to survive in a warmer world, biologists report.
Polar bears can be found throughout the Arctic in the United States (Alaska), Canada, Russia, Denmark (Greenland), and Norway. 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.
In the winter, polar bears in Alaska are found as far south as St. Lawrence Island and occasionally move down to St. Matthew Island and the Kuskokwim Delta. In the summer, bears are most abundant around the edge of the pack ice in the Chukchi Sea and Arctic Ocean.
Who is stronger polar bear or grizzly?
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.
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.
When the sea ice melts for the summer, they will migrate to the mainland such as Alaska, Canada, Russia, Norway, and Greenland, or smaller groups of islands in the Arctic. Polar bears are able to survive in temperatures between -45°C and 10°C (-50°F and 50°F).
Grizzly bears are adapted to live in different conditions ranging from elevated alpine environments to sea-level locations. No matter their elevation, they must hibernate for several months each year to survive cold conditions and scarce food supplies.

Polar bears are hunted by Alaska Natives as an important part of their culture. Polar bear meat is consumed, and their fur is used for clothing and blankets.
In the United States, polar bears are believed to be found only in Alaska. The Alaska polar bear population is estimated to be between 4,000 and 7,000 individuals.
What makes the South Pole so much colder than the North Pole is that it sits on top of a very thick ice sheet, which itself sits on a continent. The surface of the ice sheet at the South Pole is more than 9,000 feet in elevation--more than a mile and a half above sea level.
The people who travel to or live in Antarctica fall into two main groups, those who live and work on scientific research stations or bases, and tourists. No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. It has no commercial industries, no towns or cities, no permanent residents.
Can polar bear survive in desert?
Polar bears need to live near the arctic circle because if they live in the desert, they will die because they will not adapt well to the weather. Polar bears also live in the arctic because they camouflage really well, because their fur is white and most of the landscape in the arctic is white.
Tennessee has two main black bear populations: the Appalachian Population along the Tennessee-North Carolina border and the Cumberland Population in the northern part of the Cumberland Plateau along the Tennessee-Kentucky border.
Black bears can typically be found in three distinct regions in Georgia, although they will range over larger areas in search of food. They can be found in the North Georgia mountains, along the Ocmulgee River drainage system in the central part of the state and in the Okefenokee Swamp in the southeast.
Like other marine mammals, polar bears not only can swim, but love to swim (to a point). Unlike, say, a beluga whale, polar bears are not found solely in the water, but they depend on the sea so much that they're classified the same way as a seal or cetacean.
The only species of bear found in Florida would be the black bear. No grizzlies, no brown bears and definitely no polar bears are seen here. At this time in history there are only about 4,000 left in our state, and that does not include the approximate 1,500 cubs.
