Whoops (Part 78,392)

clipped from wattsupwiththat.com The whole point with CO2 as the important main temperature driver was, that already at small levels of CO2 rise, this should efficiently force temperatures up, see for example around -6 thousand years before present. Already at 215-230 ppm, the CO2 should cause the warming. If no such CO2 effect already at 215-230 ppm, the CO2 cannot be considered the cause of these temperature rises. So when CO2 concentration is in the area of 250-280 ppm, this should certainly be considered “the area of maximum CO2 warming effect”. The problems can also be illustrated by comparing situations of equal CO2 concentrations: So, for the exact same levels of CO2, it seems we have very different level and trend of temperatures: How come a CO2 level of 253 ppm in the B-situation does not lead to rise in temperatures? Even from very low levels? When 253 ppm in the A situation manages to raise temperatures very fast even from a much higher level? CO2 is easily overruled by other effects
