Newborn polar bears are able to survive in the bone-chilling Arctic winter, where the temperature can drop to negative 30 degrees Celsius or lower, there is that warmth in their mothers ‘ burrows. However, a new study suggests that if current trends continue, the cubs along Alaska’s arctic coast, would have perished out of place.
The study, presented at a meeting of the American Geophysical Union this month, which suggests that the mother polar bear will no longer be able to look into the deep snowbanks, they need to dig a hole at the end of the century.
“They need that habitat to give birth,” Megan Liu, an internal inquiry, the results of the studies, told Science. The analysis shows that, if we don’t reduce emissions soon, in the centuries, there’s going to be a long period of time when there is no available denning habitat for polar bears.”
Their work is focused on the Beaufort Sea coast, where the reduction in sea ice hit bears hard — as in the previous study, it has been shown.

Although scientists have been aware of the potential impact of climate change on polar bears over the years, the majority of studies have focused on the loss of their sea ice hunting grounds, and Steven Amstrup, who is overseeing a polar bear research for the U.s. Geological Survey for three decades, explained Inside of a research.
There are some parts of the Arctic the warming of the earth at a slower rate than the other, but Armstrup, who was not involved in the study, said the trend could affect the areas adjacent to the arctic coast of Alaska.
“In the end, all of the places that will be warmer,” Amstrup said In the scientific community. “If we don’t stop global warming, and ultimately all polar bear habitat that will be affected by it.”
