"Alarmistien" teoria pohjaa oleellisesti nk. Mann´in jääkiekkomailakäyrään, jolla pyritään todistamaan nykyinen lämpötilan nousu (sikäli kuin sitä edes on) johtuvaksi ihmisen toiminnasta. Kahden sveitsiläisen tutkijan vertaisarvioitu tutkimus kuitenkin todistaa keskiajan, noin 1000 v sitten, lämpöperiodista, jolloin nykytilanne olisi aivan normaalia vaihtelua, antropogeenista tekijää ei tarvittaisi selitykseksi.
Täällä TUTKIMUS
"This finding, if true, would be of great significance to the ongoing debate over the cause of 20th-century global warming, because, in the words of Esper and Frank, "heterogeneity alone is often used as a distinguishing attribute to contrast with present anthropogenic warming." On the other hand, if the IPCC's contention is false, it would mean that the warmth of the Current Warm Period is not materially different from that of the Medieval Warm Period (MWP), suggesting there is no need to invoke anything extraordinary (such as anthropogenic CO2 emissions) as the cause of earth's current warmth, which does not yet appear to have reached the level experienced a thousand years ago (when there was much less CO2 in the air than there is today), as is indicated by the materials archived in our Medieval Warm Period Project. And, of course, this outcome would also be of great significance"
