3 Physicists Use Experimental Evidence To Show CO2’s Capacity To Absorb Radiation Has Saturated
By Kenneth Richard on 23. April 2024
Excerpt:
Adding CO2 to the atmosphere can have no significant climatic effect when rising above the threshold of about 300 ppm. Due to saturation, higher and higher concentrations do not lead to any further absorption of radiation.
If one were to paint a white surface black so as to allow it to absorb as much heat as possible, it is well known the first layer of paint has the most dominant impact on heat absorption. A second coat covers up any remaining grayish color and perhaps a few spots missed on the first layer. By the third layer, there is effectively no more heat absorption that can be attained with the additional coat, as the surface is saturated in black. It cannot become blacker.

Another Climate Sensitivity Study Finds Doubling CO2 Leads To 0.5°C Warming At Most
By Kenneth Richard on 20. December 2024
Excerpt:
The evidence that rising CO2 concentrations lead to inconsequential warming keeps piling up.
In a new study, seven Viennese researchers provide more evidence the CO2 absorption band is already saturated at today’s concentrations (over 400 ppm). Rising CO2 levels thus cannot drive significant global warming.

Greenhouse Efficiency Insights
Guest Post by Willis Eschenbach

Excerpt:
Abstract: Using the CERES satellite data, it is shown that over the last ~ quarter century, the increase in greenhouse gases has had no detectable effect on the global average surface temperature. On the contrary, the overall increase in available solar energy after albedo reflections is shown to be sufficient to explain the warming. In support of this, variations in available solar energy are shown to agree quite well with the variations in the observed temperature. Go figure.
I got to thinking again about how to measure the efficiency of the very poorly-named “greenhouse effect”, which has absolutely nothing to do with actual greenhouses like the one shown above. Here’s an overview of some of the major energy flows of the climate system.
