New Research Evaluates Anthropogenic Fossil Carbon Dioxide and Claims of Its Dominance and Role in Global Warming
Posted on July 15th, 2020

As many of you may know, the three owners of RSCS are all alumni of the University of Massachusetts – Lowell’s radiological health program. Their college mentors, Ken Skrable, George Chabot and Clay French, performed an exhaustive and compelling analysis of the potential cause (or lack-thereof) of global warming and prepared a scientific article that details their conclusions (links below). 

Most people believe that global warming is due to increases of CO2 released to the atmosphere from the burning of fossil fuels by humans (i.e. anthropogenic CO2). Here are a few things you may not know.

1. ‘Most’ carbon in the environment contains a radioactive isotope of carbon (carbon-14) at low but measurable levels. This is formed by nuclear reactions in the upper atmosphere from radiation emitted by the sun at a very constant level over the eons. We use this fact to do carbon-dating of old bones and other old organic matter. The exception to this is fossil fuels, which has virtually no C-14 remaining because of its age and the 5,730 year half-life of C-14.

2.  NOAA has been conducting air sampling at 2 mountain-top locations since 1959 where they measure CO2 and C-14 in the atmosphere.

If burning fossil fuels were the culprit for increasing CO2 levels then we would see a predictable decrease of C-14 specific activity, as the lack of C-14 in fossil fuels would dilute the predictable C-14 in the atmosphere. As indicated in the Figure above, as the anthropogenic component increases, the specific activity of carbon-14 decreases in a very predictable way as a result of the dilution of the initial specific activity in 1750 by the anthropogenic fossil component. In 2020 (i.e. 270 y since 1750), the specific activity is 13.81 dpm/gC, and the anthropogenic fossil component is 51.07 ppm, which is 12.4% of the total carbon dioxide of 411.36 ppm (not shown in Figure). Thus, carbon dioxide present in the atmosphere in 2020 from the burning of fossil fuels does not dominate the total, and it cannot be the primary cause of global warming.

Attempts to present this analysis to NOAA with the hope of obtaining a review and constructive criticism of the approach and methodologies taken have not been successful. We believe the research conducted by Ken Skrable, George Chabot and Clay French provides an unbiased analysis that has scientific merit. While the conclusions provided may be contrary to what many believe, we are presenting this research as it may have significant implications on the issue of global warming, its world-wide cost, and global politics.

Three separate documents describing this issue in detail are available for review; a synopsis of the research, an essay "Anthropogenic-fossil and Non Fossil Components of Mauna Loa and Niwot Ridge Annual Mean Carbon Dioxide", and the article "Anthropogenic Fossil Carbon Dioxide and Claims of Its Dominance and Role in Global Warming". Links for the documents and email addresses of the authors are below. Interested readers are encouraged to share this research with their colleagues.
