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 CO $_2$ 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 CO $_2$ on the absorption of Earth's blackbody radiation in the 12-15 $\mu$ m region. The influence of doubling the concentration of CO $_2$ in the atmosphere on the surface temperature is not $\Delta$ T=0.02K, or even $\Delta$ T=0.4K if only one of the two mistakes in Smirnov's analysis is corrected. The correct value lies within $\Delta$ T=1.1-1.3K as outlined by other authors analysis using simplified, yet more theoretically consistent models.
