Warmer Arctic = Colder Winter??
LOLOLOLOLLL.
It depends on where you are. Climate is sorta like a water balloon; squeeze it in once place and it pops out in another. For example, when it's warmer in the northern hemisphere, like it was after the last ice age, then it gets cooler and wetter in North Africa. In this case, warming the Arctic, and exposing the relatively warm water that's normally hidden under colder ice, and you see weather further south getting colder.
Now the real question is: Did Americans in their SUVs cause this? That's what St. Algore of Warmth would like you to believe. The answer is, of course, "Stop smoking meth, Mr. Vice-president". It was considerably warmer 8000 years ago, despite the lack of Ford Expeditions. And now we may be returning to that climate. But what was once thought of as the "Holocene climate optimum" is now something that St. Algore says we should avoid at all costs. Go figure.
