…he speaks of a time in the earth’s history where Greenland was mostly farmland, England was the best place to grow grapes for wine, he speaks of a Little Ice Age that I’ve read apparently just ended in the 19th century, …

Sorry, but that is just nutty. Think about this: Greenland is mostly covered by an ice sheet currently. If it “was mostly farmland” as recently as just a couple of centuries ago, do you think scientists could be drilling ice cores all over Greenland, that go back thousands to hundreds of thousands of years?

England is not the best place to grow grapes. That someone could grow grapes there in the medieval period is hardly an endorsement that it was the best place. BTW, one can grow certain varieties of grapes there now.

The Little Ice Age was a period of cooling for a few centuries.

Please see the AIP link up thread, on the Discovery of Global Warming, where you will find the facts.
