Bart, you write “You demand impossible perfection. Your argument is hubris.”
Complete an utter garbage. The standard practice in signal to noise ratio calculations is to be able to distignuish a singal above the level of the background noise. The IPCC and the proponents of CAGW have always claimed that the CO2 signal is so strong that it overwhelms all the background noise.
So if the CO2 signal is so strong, then it ought to be detectable above the background noise. It is not. There is no CO2 signal in ANY temperature/time graph. This complete absence of any CO2 signal proves beyond all doubt that the hypothetical and meaningless estimations of the climate sensitivity for a doubling of CO2 are simply wrong. These hypothetical estimations are either IMPOSSIBLE to measure or have never been measured.
According to the time honored scientific method, if the observed data is different from the hypothetical data, we ALWAYS believe the observed data.
The climate senstitivity for a doubling of CO2 from current levels is proved to be indistinguishable from zero. Period.
