I had countless discussions on Climate Change and in each and every one of them, the Medieval and the Roman War period cause the most distress. Climate Alarmists go to ridiculous lengths and dismiss evidence that they themselves brought into the discussion as soon as I show them that their own evidence actually confirms my point of view. Imagine this – you say A, I say B, you prove to me and the auditorium that the evidence I brought in in order to support my claim for B actually confirms A. I turn around and dismiss my own evidence as irrelevant. It has happened to me so many times, I stopped counting a long time ago but it shows how dishonest the debate is. The Holocene Highstand is just more water ion my mills.
Most skeptics are familiar with the Warmunist efforts to erase the Medieval Warm Period and Little Ice Age.
