Oh, and I forgot to post this clip from the article above:

"Some scientists who have long doubted that a human influence could be clearly discerned in the Arctic's changing climate now agree that the trend is hard to ascribe to anything else.

"We used to argue that a lot of the variability up to the late 1990s was induced by changes in the winds, natural changes not obviously related to global warming," said John Michael Wallace, a scientist at the University of Washington. "But changes in the last few years make you have to question that. I'm much more open to the idea that we might have passed a point where it's becoming essentially irreversible.""


Thank you, "Mr. Science"...
