"Scientists have found other indications of global cooling. For one thing, there has been a noticeable expansion of the great belt of dry, high-altitude polar winds — the so-called circumpolar vortex — that sweep from west to east around the top and bottom of the world." — Time Magazine, June 1974.

"It may well be that global warming could be making the occasional bout of extreme cold weather in the U.S. even more likely. Right now much of the U.S. is in the grip of a polar vortex, which is pretty much what it sounds like: a whirlwind of extremely cold, extremely dense air that forms near the poles." — Time Magazine, January 2014.

Yeah, right. We were all against it before we were for it … or was it the other way around?
