Climate change set to wipe out polar bears by turn of century, study finds


Climate change is starving Polar bears extinct, according to a study released Monday that predicted apex carnivores could almost disappear within a human lifetime. In some areas they are already caught in a vicious downward spiral, with shrinking sea ice reducing the time bears have to hunt seals, scientists reported in Nature Climate Change.Their declining body weight reduces their chances of surviving arctic winters without food, the scientists added.

“The bears face an increasingly long period of fasting before the ice sets in and they can return to feed,” Steven Amstrup, who designed the study and is chief scientist, told AFP. by Polar Bears International.
