A new study indicates that the last ice age, known as the Younger Dryas period, impacted in as little as one year. There were seasonal variances that were more extreme leading up to it, but it just flipped to freezing cold fast.

The proof of an extreme cooling within a short number of years 12 700 years ago was attained in sediments of the volcanic lake "Meerfelder Maar" in the Eifel, Germany. The seasonally layered deposits allow to precisely determine the rate of climate change. With a novel combination of microscopic research studies and modern geochemical scanner procedures the scientists were able to successfully reconstruct the climatic conditions even for individual seasons. ed.z.: and wouldn't that happening again be just some fun...

What will happen (is happening) to existing wind patterns as the earth transitions away from two stable polar ice caps (arctic and antarctic) to a single polar ice cap (antarctic only)?

What's strange is they don't mention that there was a comet impact at about that same time in North America, which would seem to have caused major wind shifts and other climate disruptions.

It would be an extremely interesting test of man-made global warming- as every industrialized nation on earth would, in the course of a year, take the pollution controls off the smoke stacks and encourage MASSIVE biomass energy conversion in an effort to trap heat in the atmosphere.
