Will polar bears go extinct in 2022?
There are about 22,000 to 31,000 polar bears in the Arctic wilderness, and they can be found in Alaska, Canada, Greenland, Russia, and Norway. But according to a study published in Nature Climate Change, polar bear populations will decrease—and even disappear—by 2100.
Will polar bears ever go extinct?
There is evidence from DNA that some polar bears may be mating with brown bears. So it's possible that polar bears will evolve away by giving up on the ice, moving back into the forest, and mating with brown bears. But polar bears as polar bears will certainly cease to exist once the ice ceases to exist.
Will polar bears go extinct by 2100?
The study links the animal's demise by 2100 in Arctic regions to the complete melting of summer ice under a scenario of high greenhouse gas emissions, making it near impossible for ice-dependent polar bears to survive by the end of the century.

Arctic foxPolar bear / EatsThe Arctic fox, also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. Wikipedia
What is the future for polar bears?
Scientists predict that if current trends continue, the polar bear population will shrink by two-thirds by the year 2050 and faces a high risk of extinction by the end of the 21st century.

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.
How can we stop polar bear extinction?
We can all contribute to reducing climate change, and therefore help polar bears and other endangered species. A significant cause of climate change is the emission of polluting gases from burning fossil fuels, such as coal and oil. Fossil fuels are burned when we use electricity or drive our cars, among other things.
Why will polar bears go extinct?
By century's end, polar bears worldwide could become nearly extinct as a result of shrinking sea ice in the Arctic if climate change continues unabated, scientists said.
How long will polar bears be gone?
On current trends, the study concluded that polar bears in 12 of 13 sub populations analysed will have been decimated within 80 years by the galloping pace of change in the Arctic, which is warming twice as fast as the planet as a whole. There is not enough data for six others to make a determination as to their fate.
How many polar bears are left in the wild?
There are approximately 25,000 polar bears left in the wild today. The challenge to their survival has long been understood, but the new study, building on pioneering work by Amstrup a decade ago, is the first to put a timeline on their likely demise.
How long can bears survive without food?
A male bear, for example, in the West Hudson Bay population that is 20% below its normal body weight when fasting begins will only have enough stored energy to survive about 125 days rather than 200 days. New-born cubs are even more exposed, according to the study, especially when mothers have not fattened up enough to provide nourishing milk. Females without offspring, however, have the greatest capacity to withstand long periods without food.

Is the polar bear endangered?
Half of Earth’s land-based mega fauna are classified as threatened with extinction, but only polar bears are endangered primarily by climate change. But that status may not be unique for long, and should be seen as a harbinger of how climate will impact other animals in the coming decades, the authors warned.
Is there a plan B for polar bears?
Dire predictions for polar bears has led to the mulling of alternative solutions, such as captive breeding programmes or air lifts to Antarctica, but there is no ‘Plan B’. “The only way to save them is to protect their habitat by halting global warming,” said Amstrup.

Do polar bears hunt seals?
Polar bears are specialized hunters. They rely heavily on ringed seals for the consumption. Bears hunt seals on the sea ice and if more and more ice transforms into water the bear’s hunting platform disappears. As it turns out less than two percent of the hunts end up successful.
How long will polar bears live before extinction?
The heating of the planet is pushing Earth’s polar bear population to its limit, and according to a new study, they could have fewer than 100 years left before extinction.

Polar bears evolved from brown bears to withstand cold and freezing temperatures. Climate change is threatening to diminish the polar bear population by 2100. However, the polar bears could adapt like they did before.
Where do polar bears live?
Polar bears live in Antarctica and artic regions. Their fur coats keep them warm in these frigid areas. This means they can only function in those areas. But their habitat is threatened by global warming. Global warming is melting the glaciers and ice plains, minimizing the amount of territory polar bears and their prey’s territory. At this rate, will polar bears be extinct in the future?
