Polar bears have always eaten dolphins.
Dolphins are not a mainstay of a polar bear's. Too lean. Besides, Dolphins are summer visitors that far north.
But they are protein.
From Fox News:
Faced with a rapidly changing habitat, polar bears are adapting with a new entrée: For the first time, a polar bear was seen preying on a white-beaked dolphin carcass that had been trapped in the ice in Svalbard, a group of Norwegian islands in the Arctic Ocean.
In April 2014, a male polar bear with a full belly was spotted near a recently devoured white-beaked dolphin, which could have weighed 120 to 680 lbs. and measured 5 to 9 feet long, the researchers said in an article published online June 1 in the journal Polar Research. The bear was also seen with another white-beaked dolphin’s thawing carcass, which he was likely saving for a later meal.
These dolphins rarely venture so far north in the Arctic; they prefer the sub-Arctic, which has less sea ice and more open water. "If it had been a more usual sea-ice year, I do not think the dolphins would have been that far north in the spring," said Jon Aars, primary author of the study and a research scientist at the Norwegian Polar Institute.
The surface water temperature of the Arctic Ocean surrounding Svalbard has increased significantly over the past 45 years, leading to decreases in summer sea-ice cover over the entire Arctic Ocean and extreme melting during 2007, according to research published in 2008 in the journal Geophysical Research Letters.Dropping required science classes in favor of women's studies and black history have ruined two generations of people with college diplomas. Sad to see Fox News fall for this.
The surface temperaures are measured by promoters of this junk science.
By the way, polar bears don't drink Coke.
