by W. A. van Wijngaarden The effect of changing greenhouse gas concentrations, most notably carbon dioxide, CO2, on climate was examined. In particular, calculations of the climate sensitivity, the warming of the Earth due to a doubling of atmospheric carbon dioxide, are discussed. Greenhouse gas concentrations, as determined from air bubbles trapped in ice as… Continue Reading
G. Shanmugam Department of Earth and Environmental Sciences, The University of Texas at Arlington, Arlington, Texas 76019 ABSTRACT The geologic record shows that the Earth’s climate has always been changing naturally during the past 600 million years in terms of CO2 and temperature, without CO2 emissions from Fossil Fuels by humans. There were both warming… Continue Reading
Download the entire PDF Nitrous Oxide Summary by Gregory Wrightstone and C. A. “Kees” de Lange Nitrous oxide (N20) has now joined carbon dioxide (CO2) and methane (CH4) in the climate alarm proponents’ pantheon of anthropogenic “demon” gases. In their view, increasing concentrations of these molecules are leading to unusual and unprecedented warming and will,… Continue Reading

Van Wijngaarden and Happer Radiative Transfer Paper for Five Greenhouse Gases Explained
by Dr. C.A. de Lange In 2019, William. A. van Wijngaarden and William Happer published a seminal paper on the radiative transfer process titled: Infrared Forcing by Greenhouse Gases. In it, they reviewed how the atmospheric temperatures and the concentrations of Earth’s five most important, naturally occurring greenhouse gases, H2O, CO2, O3, N2O and CH4… Continue Reading
On Climate Sensitivity by Richard S. Lindzen, Ph.D. with review assistance from Roy W. Spencer, Ph.D. June 2020 Editor’s Note This is a superb paper to kick off the CO2 Coalition’s Climate Issues in Depth Series. The topic lies at the heart of the public policy debate over climate and energy, and the author is… Continue Reading
The paper’s Abstract explains that while the “radiative forcing” of each methane molecule is indeed 30 times larger than that of a carbon dioxide molecule, the increase in global methane is 300 times less than that of carbon dioxide. As a result, methane is only one tenth (30/300) as powerful in forcing as carbon dioxide, which adds about a degree Celsius to global warming as it doubles in the atmosphere. A methane doubling would provide only a tiny fraction of total greenhouse forcing, the paper says.... Continue Reading

The purpose of this paper is to explain how the data set that is referred to by policy-makers and the media as the global surface temperature record is actually obtained, and where it fits into the popular narrative associated with climate alarm. ... Continue Reading
