In May 2000, the United States added the polar bear to the list of threatened species protected under the US. Endangered Species Act. Activists had supported the listing for a number of years, recognizing that polar ice cap was melting at even a greater rate than predicted

With new estimates that it might melt completely by 2099 Polar bears reply on the ice cap to stage their hunting of ringed seals and other prey, so the loss of the ice poses a distinct threat to their survival.

While a robust male polar bear can measure 11 feet tall and weigh up to 1,200 pounds, there is evidence that the species is losing its physical strength, good health and suffering a decline in size. There has also been a noticeable decline in the survival rate of cubs, which usually are born as twins in the winter.

The Newborn polar bears can able to survive the bone chilling Arctic Winter where the temperature are lower than minus 30 degree Celcius by getting warm from mother bear.

The New Research says that the recent climate changes along Alaska northern cost might perish outside instead.

The American Geophysical Union , suggests that mother polar bears may no longer be able to locate the deep snowbanks they need to dig dens by the end of this century.

“They need that habitat to give birth,” Megan Liu, a research intern who presented the findings

“if we don’t restrict our emissions, very soon, within the century, there’s going to be an extended amount of time when there’s no available denning habitat for the polar bears.”
