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

Methane and Climate

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 Global Mean Temperature Anomaly Record

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
