    Just remember, Michael Mann declared both the Medieval Warming and the Little Ice Age as non-existent. Beware that he likes to sue those who disagree with him.

      Let him sue. What an ignorant idiot he has shown himself to be…..but there will still be those unthinking, illiterate bigots, who prostrate themselves at the fount of his immense scholarship……..

        You left out narcissistic.

        My late mother’s maiden name was and my middle name is Reynolds. Christopher Reynolds came to Virginia in 1622.

    The quote from Bronowski: “I’m not here to worship what is known, but to question it” is just as relevant to this article. I know it is only a summary of something much longer, but I find it hard to get any enthusiasm for it without even a hint at how the study reached its conclusions. It was a “reconstruction of chironomids”, (which my dictionary tells me are midges). What was the methodology, what was the biggest potential source of error, and how did they cope with it?
    Yes, I know that would have taken an extra three or four sentences and this article is just a sound-bite, but without it we are no better than alarmists who claim “the sky is falling” (their methodology = ask a small selection of the 95% of climate-change scientists who rely on research grants for their living if they think it’s raining today, then infer wildly……)

      “…just a sound bite…”

      I agree that one needs more.

      A “reconstruction of chironomids” means a reconstruction of the summer temperatures when their larvae were flourishing; all based on ancient sediments of lakes.This sort of thing:

      It is (apparently – I had never heard of it!) quite a well established technique in the study of historic lakes. It uses a statistical technique involving preliminary estimation of “a transfer function” – and this is perfectly all right in principle. How far one should go in reporting such inferences in triumphalist terms…well I would be cautious.

    The continuing onerous and hostile debate about the mwp has no end because neither side in the debate acknowledges the uncertainty issue.

      Yes, and there is considerable uncertainty about current global temperatures as well!
