National Geographic Documentary - Polar Bears Lifes - Wildlife Animals Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species, and at least three of the nineteen polar bear subpopulations are currently in decline.

- Status of these populations: Polar bears in these areas are faring well now, but scientists predict that ice in these areas will disappear within 75 years—and, with it, resident polar bear populations—unless action is taken to reduce carbon emissions.

Polar bear Global Warming and Polar Bears. The chief threat to the polar bear is the loss of its sea ice habitat due to global warming. As suggested by its specific scientific name (Ursus maritimus), the polar bear is actually a marine mammal that spends far more time at sea than it does on land.s climate change melts sea ice, the U.S. Geological Survey projects that two thirds of polar bears will disappear by 2050. This dramatic decline in the polar bear is occurring in our lifetime, which is but a miniscule fraction of the time polar bears have roamed the vast Arctic seas.

Where Do Bears Live | Bears Distribution and Habitat Of all the bear species, the brown bear is the most common and is found in Western Europe, western North America, and Asia. The American black bear is the inhabitant of North America while polar bears are limited to Arctic and Polar Regions.he polar bears inhabit all throughout the range of Arctic and Polar Regions that can be as far south as Newfoundland Island. Human’s absence in these cooler regions allows the largest carnivore to retain its original habitat. They are known to reside in the north of 88 o in the James Bay in Canada.

The Polar Bear Habitat The Polar Bear Habitat. The polar bear habitat encompass the entire circumpolar Arctic region. Polar bears have adapted to be able to live in the water and on land. Unlike other bear species, the polar bear are excellent swimmers, and have been spotted more than 100 miles away from land or ice.

Polar Bear A symbol of the Arctic, polar bears are the world’s largest land predator and biggest member of the bear family. With heavy fur, blubber up to four inches thick and black skin that absorbs heat from the sun, polar bears are amazingly well adapted to the Arctic climate. Denning females spend long periods of time largely immobile without eating or drinking, yet they do not lose bone mass or suffer from lack of water.

Polar bear status, distribution & population By 2040, scientists predict that only a fringe of ice will remain in Northeast Canada and Northern Greenland when all other large areas of summer ice are gone. This Last Ice Area is likely to become important for polar bears and other life that depends on ice.

Alaskaâs Polar Bears Polar bears are found in the circumpolar north in the U.S. (Alaska), Canada, Greenland, Russia and Norway. There are 19 distinct sub-populations. STATUS: “Threatened species” under US Endangered Species Act (May 2008). “Vulnerable” under IUCN’s Red List of Threatened Species.

- It can also be found in the grassland biome. Finally polar bears live in the tundra region. They are big, fluffy, white bears that can grow 7 - 8 feet tall. They prey upon large and small mammals, fish, birds, berries and leaves. Polar bears are found in the coasts, tundra, living on shore line and ice floats.

Study: Polar Bear Populations Have Plummeted 40 Percent in Alaska and Canada “We see low survival for a couple of years where the population takes a downward step, then levels off for a while.”. During the years of steepest decline, between 2003 and 2007, polar bear cubs fared the worst. Just two out of 80 cubs documented in Alaska during those years are known to have survived. Though adult and cub populations began to improve in 2007, the number of subadult bears—those between the ages of two and four—has continued to fall.

Polar bear Polar bears live across 1 million square miles of open tundra and sea ice encircling the North Pole. Their range spans the far northern reaches of Alaska, Canada, Russia, Greenland, and Norway. Polar bears are the largest member of the bear family. Adult males weigh up to 1,400 pounds and stand up to 11 feet tall on their hind legs.

Study: Polar Bear Populations Have Plummeted 40 Percent in Alaska and Canada Previous studies linked declines in summer sea ice due to warming temperatures to “reduced physical condition, growth, and survival of polar bears,” the report said. Polar bears depend on sea ice to let them travel across the frozen water to hunt for seals—their preferred diet—that emerge through cracks in the ice to breathe. The study found that low survival rates from 2004 through 2006 led to a 25 to 50 percent decline in the number of bears in the region.

- Though they are excellent swimmers, polar bears spend most of their time atop Arctic sea ice. Sea ice is an ecosystem in itself, supported at its base by plankton and algae at the bottom of the food chain. Polar bears share this habitat with seals, whales, Arctic foxes, birds and even people.

Why do polar bears have white fur? And nine other polar bear facts Why They Matter. Importance of polar bears Polar bears are at the top of the food chain and have an important role in the overall health of the marine environment. Over thousands of years, polar bears have also been an important part of the cultures and economies of Arctic peoples. Polar bears depend on sea ice for their existence and are directly impacted by climate change—serving as an important indicator species.

- Polar bears are the largest carnivores and a unique symbol of the Arctic. Nineteen populations of polar bears are distributed in Alaska, Canada, Greenland, Norway, and Russia. The world wide population is estimated to be 22,000-25,000 bears. In Alaska, the Marine Mammal Protection Act (MMPA) protects polar bears by prohibiting take of polar bears.

KidZone Animal Facts The Polar Bear The polar bear or the sea/ice bear are the world's largest land predators. They can be found in the Artic, the U.S. (Alaska), Canada, Russia, Denmark (Greenland), and Norway. Each of these countries either banned hunting or established rules for how many polar bears could be hunted within its own boundaries. These rules help keep polar bear populations stable. Today, 25,000 to 40,000 polar bears roam the Arctic.

Polar Bear Facts As the ice retreats north during the summer months, polar bears travel with the ice floes and continue to hunt seals (Stirling and Guravich 1990, p 61). Polar bears are usually found in the northern marine areas of Alaska, the Commonwealth of Independent States, Norway's Svalbard Archepelago, Greenland and Canada (Lynch 1993, p 5). Scientists estimate there are between 25,000 to 40,000 polar bears in the world.
