Response to Letters to the Editor by Mr. Waller Wilson

In response to Mr. Wilson’s request for “C.J. Cook to cite some sources for his/her opinion,”.

First, some house cleaning: it is his, not her; C.J. stands for Cyril Joseph. Second when I submitted the article to the Royal Examiner, I had footnoted my sources in the article’s footer. I don’t know why they did not appear in the post. They are repeated here for info: “Hot Talk Cold Science” by Singer, Chapter 6 p77, “Dark Winter” by Casey, Appendix 3 Figure A3-2 p89.

As to the question on CO2, chapter 10 of “Hot Talk Cold Science” (revised and expanded third edition copyright 2021) is devoted to the subject of CO2in the atmosphere. Chapter 10, page 130, states: “Greenhouse gas” means only that CO2 absorbs some radiation; it does not guarantee climate warming, the forcing of CO2 depends on where it is in the atmosphere. Its actual behavior depends mostly on atmospheric structure, expressed by atmospheric lapse rate (ALR), and is defined as the change in atmospheric temperature with altitude.

The Atmospheric Lapse Rate (ALR) is different for the three regions of the atmosphere. The ALR is positive for the Stratosphere, Zero for the Tropopause, and Negative for the Troposphere. This supports the principle that depending on where in the atmosphere, the radiation on the CO2 molecules can produce cooling. The following statement on the Climate4U website is taken from a graph of CO2 in ppm and HadCRUT3 temperature.

Climate4You website 20080927: Reflections on the correlation between global temperature and atmospheric CO2 “By this, the diagram illustrates that the overall relation between atmospheric CO2 and global temperature apparently has changed several times since 1958.

In the early part of the period, with CO2 concentrations close to 315 ppm, an increase in CO2 was associated with decreasing global air temperatures. When the CO2 concentration around 1975 reached 325 ppm, this association changed, and increasing atmospheric CO2 was now associated with rising global temperatures. However, when the CO2 concentration at the turn of the century reached about 378 ppm, the association possibly changed back to that, characterizing the period before 1975, before apparently changing again around 2014.” So the curve fit shows a decrease after 1958 followed by an increase until July of 2022, when it slope became negative again. The data and graph were updated on 8 September 2022.

These are the sources (and some additional data) you requested.
