There is ‘No Role of CO2 in Any Significant Change of the Earth’s Climate’

An updated review about carbon dioxide and climate change Vol.:(0123456789)1 3Environmental Earth Sciences (2018) 77:262 https://doi.org/10.1007/s12665-018-7438-y , by Dr. Rex J. Fleming

“One can summarize these calculations as follows: whatever the “climate-change regime,” whatever surface heat from the Sun on any given day within that regime, that heat is fully absorbed and fully vertically redistributed throughout the troposphere—there is no propensity for CO2 to store heat in a systematic way over time to produce a climate change effect (as defined in the introduction).”

“Why does the integrated effect of CO2 have so little effect on the total temperature profile? The reason is that the Planck function change with height (temperature) is very strong in reducing the intensity of those relatively few lines with large absorption coefficients. Another reason is that the longwave radiation is diffuse which depletes the intensity rapidly over distance. The diffuse nature of the radiation also leads to the fact that the net radiation for a given level (that sent upward at the bottom of a layer, minus that sent downward at the top of a layer) further reduces the adsorbed CO2 radiation intensity.”

“Other so-called “greenhouse gases” (some with larger absorption coefficients, but all with significantly less concentration) have their intensity quickly transferred upward and depleted by the same strong Planck function intensity change that applies to CO2 and H2O. From the historical record and from these calculations one sees that the CO2 concentration had no impact on temperature. It contributes low-level heating and allows upper level cooling for a zero net effect.”
