Rather than engaging in endlessly nitpicking, unproductive arguments over unknowns such as the logarithmic exponent describing the almost nonexistent / nonexistent effect of carbon dioxide on temperature, and the «estimate» of CO2 sensitivity, let's look at empirical evidence, and the big picture: CO2 is rising, and the planet's temperature is falling.

I want to look at a few other methods of analyzing the data, for example a logarithmic method of analyzing CO2 and taking out CO2 seasonality might allow use of the data without any moving averages.

«The proportionality of warming to cumulative emissions depends in part on a cancellation of the saturation of carbon sinks with increasing cumulative emissions (leading to a larger airborne fraction of cumulative emissions for higher emissions) and the logarithmic dependence of radiative forcing on atmospheric CO2 concentration [leading to a smaller increase in radiative forcing per unit increase in atmospheric CO2 at higher CO2 concentrations; Matthews et al. (2009)-RSB-.

Meanwhile, the logarithmic effect of CO2 is excellent «concession» to make in the rhetorical sense, since it concedes the obvious state of our knowledge about the effects of CO2, while at the same time providing us with the solid argument that even if we double atmospheric CO2 levels from 400ppm to 800 ppm over the next 100 years the largest amount of warming possible — assuming all else remains the same and Gaia has no homeostasis negative feedback systems which tend to moderate any runaway trends — is 1.2 c.

Yes at the line center the absorption of CO2 is «saturated: — surface emission totally replaced by emission from the top of the ghg column but as the conc of the ghg increases, the line width increases so the ghg starts to absorb over a greater and greater range of wavelengths — this is the cause of the logarithmic relationship between concentration and absorption.
