I think you need to check your facts "Decaff". That data that goes back for millenia is incomplete, and often "guessed". You see, ancient man didn't have modern instruments for tracking weather, even temperature so we don't really know with 100% accuracy what the weather was like in 1006. In fact, we can't be completely sure of what it was like in 1806 because THE RECORDS ARE INCOMPLETE. It's all guesswork. And contrary to what NPR would have you believe, not all scientists are in agreement on "global warming".
