Available at SSRN 2873672 https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2997420 Although the science of the greenhouse effect of atmospheric CO2 is well established, all efforts to relate this phenomenon to fossil fuel emissions have failed because of deficiencies in the methodology used in the presentation of empirical evidence. Circular reasoning is used in the IPCC carbon budget to relate atmospheric CO2 to fossil fuel emissions as a way of dealing with insurmountable measurement problems. No evidence exists to relate changes in atmospheric CO2 or the rate of warming to fossil fuel emissions because correlations presented for these relationships are spurious. The UNFCCC holds annual COP meetings and calls for reductions in fossil fuel emissions to attenuate global warming without evidence that warming is related to emissions.
