Fraudster Michael Mann: "the warmth of the medieval warm period/medieval climate anomaly simply doesn't reach modern warmth. Every peer-reviewed scientific study of the matter comes to the same conclusions"

David Rose's climate science writing shows he has not learned from previous mistakes | George Monbiot | Environment | guardian.co.uk
Rose, as usual, provides no reference for this paper, and none of the scientists I've contacted, including Mann, has any idea what he's talking about. But Mann points out that neither "we, nor any other researchers, have ever denied there was a period of relative warmth sometime during medieval for many regions. What we – and other competent researchers – have all found is that the warmth was far more regional than modern warmth, with some large regions, like the tropical Pacific, having been unusually *cold* at the time, and when you average over the globe, the warmth of the medieval warm period/medieval climate anomaly simply doesn't reach modern warmth. Every peer-reviewed scientific study of the matter comes to the same conclusions."
CO2 Science - Medieval Warm Period Project
The project's reason for being derives from the claim of many scientists -- and essentially all of the world's radical environmentalists -- that earth's near-surface air temperature over the last few decades was higher than it has been during any similar period of the past millennium or more. This claim is of utmost importance to these climate alarmists; for it allows them to further claim there is something unnatural about recent and possibly ongoing warming, which allows them to claim that the warming has its origins in anthropogenic CO2 emissions, which allows them to claim that if humanity will abandon the burning of fossil fuels, we can slow and ultimately stop the warming of the modern era and thereby save the planet's fragile ecosystems from being destroyed by catastrophic climate changes that they claim will otherwise drive a goodly percentage of earth's plants and animals to extinction. Since these are serious contentions, we feel that their underlying basis must be rigorously tested with real-world data.
