“Peer reviewed science: Polar bears of the past survived warmth“: A University of Alaska article about a fossilized polar bear jawbone, called “Polar bears of the past survived warmth“, lets Anthony Watts show his sensitive tree-hugger side:

So next time you have somebody sniffling and tearing up over polar bears and sea ice, show them this research and hand them a Kleenex. Now, they can worry about the polar bears eating hippos in the future.

I guess he didn’t bother reading the article he’s waving around as surly proof:

“Refugia” are places that polar bears may survive without ice. The Svalbard Archipelago may have been one of those places. Biologists today think polar bears would have a difficult time living on land, because other species like the grizzly bear could outcompete them.

The warm period of the Eemian might have come at a time when the polar bear wasn’t such an ice specialist, Talbot says.

Is this what a denialist slam-dunk looks like? Anthony should stick to snickering over inaccurate polar bear illustrations created by graphic artists.
