Using IPCC numbers we can expect only half a degree of warming this century. Time to Panic?

Christopher Monckton calculates below that even if we assume the IPCC and mainstream estimates are right, the warming from here to 2100 is likely to be a minor half a degree. (He doesn’t even bother to argue about whether this would be beneficial or not). Monckton just makes the point that for all the scare campaign about preventing a “two degree” apocalypse, what we are really talking about is a half degree in the next ninety years with some theoretical further warming in the centuries after that. The “two degrees” of fear is measured from the bottom of the Little Ice Age, as if that was the ideal “pre industrial” climate that we somehow want to return to.

As usual, everything about the Great Global Warming Scare falls apart under the most cursory glance, yet the billion dollar PR truck rolls on. The climate sensitivity of the IPCC dropped in Assessment Report 5 to about 2.2 C as it slowly is dragged toward a more realistic number.  The data coming in tells us that the climate feedback factors are likely net negative, so climate sensitivity is below 1°C. Hence even a  “half a degree” due to CO2 is an overestimate."
