Note: There is a way to improve on yesterday’s discussion about thermal inertia and equilibrium temperature forecasts. Carbon sensitivity theory holds that a doubling of CO2 in the atmosphere, including normal feedbacks, but absent of other forcings and their feedbacks, will result in a global average surface temperature gain of about 3C upon reaching equilibrium. Today we have added 42% to the pre-industrial CO2 level of 280ppm. Halting further increases from this level would be consistent with an equilibrium temperature increase of 1.5C, using log-scale progression figures. Superfluous methane growth that humans have caused is an unusual forcing that could add a few tenths to that number..
