Physicists G. V. Chilingar, O. G. Sorokhtin, L. Khilyuk and M. V. Gorfunkel, authors of the paper Cooling of the Atmosphere due to CO2, also published the peer-reviewed study Greenhouse gases and greenhouse effect in Environmental Geology, International Journal of Geosciences, providing physical evidence that rising CO2 should result in slight cooling of climate, and is benefitial to agricultural productivity and reforestation. The authors also find that methane accumulation has no significant effect on the climate.
Introduction: For comprehensive analysis of the influence of increasing concentration of the greenhouse gases on the global temperature of atmosphere, one needs to develop an advanced physicochemical theory of mass—energy redistribution among the Earth’s systems. This advanced theory should include: (1) evolution of the composition of atmosphere, (2) evolution of the geological conditions, (3) data on changing solar radiation, (4) the Earth’s revolution precession, (5) oceanological data, and (6) multiple feedbacks between the atmosphere and ocean.
The authors investigate the greenhouse effect using the adiabatic model, which relates the global temperature of the troposphere to atmospheric pressure and allows one to analyze the temperature changes due to variations in mass and chemical composition of the atmosphere. The existing feedbacks between atmosphere and ocean are intentionally neglected in the article with the focus on the atmospheric temperature changes due to anthropogenic greenhouse gases emission...
