The findings   43   (publish) in Science offer hope for a species that may be trending towards extinction by the end of the decade.

Although the southeast Greenland bears    48   (adapt) to their surroundings over the past decades, rising temperatures may eventually cause their glacial ice to get smaller or even disappear. As Steve Armstrup,    49    scientist with Polar Bears International , says, “While the southeast Greenland bears are able to hunt with glacial ice today, that will be almost impossible in the future     50     we control the rise of global greenhouse gases.”
