Grizzly Bears Didn't Get the Memo

Remember the claim that there is no global warming? Remember how deniers keep saying it's stopped? Apparently, the grizzly bears in Yellowstone National Park weren't listening. They're waking up a full month early. While the east has been hammered with blizzards, the west is experiencing record high temperatures. As a result, at least one bear is up and has been observed eating. The sighting occurred on February 9th. The first sightings in the past have occurred in the first half of March.

The fact that it was observed eating is an important detail because bears will sometimes come out of their dens during the winter and then go back. But, once they start eating it means they are up for good. There may have been only one bear sighted so far, but as the article states, if there is one there are probably more. And, certainly, we can expect more to come out early.

The bears wake up in response to temperature. So, if it isn't getting warmer, why are the bears waking up early?
