Comment on "Collision and radiative processes in emission of atmospheric carbon dioxide"
Abstract
Recently, Smirnov published a paper (B. M. Smirnov, "Collision and radiative processes in emission of atmospheric carbon dioxide", 2018, J. Phys. D.: Appl. Phys., Vol. 51, No. 21, pp. 214004) which dismisses the role of increasing concentrations of anthropogenic CO2 on global warming of planet Earth. We show that these conclusions are the consequence of two flaws in Smirnov's theoretical model which neglect the effects of the increased concentrations of CO2 on the absorption of Earth's blackbody radiation in the 12-15μm region. The influence of doubling the concentration of CO2 in the atmosphere on the surface temperature is not =0.02K, or even =0.4K if only one of the two mistakes in Smirnov's analysis is corrected. The correct value lies within =1.1-1.3K as outlined by other authors analysis using simplified, yet more theoretically consistent models.
