• CO2 to temperature causal relationship

  The author seems to have done a very rigorous analysis and made a good argument. The only problem I have is that this entire analysis rests strongly on the premise that there is a direct, causal (and linear) relationship between atmospheric CO2 concentration and average surface temperature. This seems to be accepted as fact without any evidence, not just here, but everywhere in popular culture. Can anybody point me to some information that shows this causal relationship? I have seen evidence of a correlation between CO2 and temperature but no strong argument for the accepted causal relationship. As correlation and causation are not the same thing, a perceived rise in temperature could just as well cause a rise in CO2 concentration as be caused by it or any number of other possible variables.
