Methane and Climate

Methane and Climate

W. A. van Wijngaarden and W. Happer

November 26, 2019

The CO2 Coalition is pleased to present a new paper in our Climate Issues in Depth series, titled Methane and Climate   The paper was written by CO2 Coalition founder and board member Will Happer, a Princeton physics professor, and W. A. van Wijngaarden, of the Department of Physics and Astronomy at York University, Canada. Happer recently served as director of emerging technologies at the National Security Council, where he was President Trump’s top adviser on climate science.

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.

The paper uses spectroscopic measurements from the HITRAN data base of the Air Force Cambridge Research Laboratories.  The minute effect of methane emissions is summarized by numbers and figures in the paper.

The Life:Powered Initiative of the Texas Public Policy Foundation included the  paper as the scientific basis for a letter submitted to the Environmental Protection Agency opposing the regulation of methane during oil and gas extraction and pipeline transportation. Some states and countries have been imposing restrictions on extraction, pipelines, and animal husbandry because of fears of methane’s warming potential. Even “cow farts” have been cited as a concern for Green New Deal legislation, which calls for the end of fossil-fueled energy. Over 80 percent of U.S. and world energy comes from fossil fuels.

Ocean Health – Is there an “Acidification” problem?

The CO2 Coalition of climate scientists today released a White Paper analyzing decades of peer-reviewed research on the impact on the oceans of carbon dioxide emissions from the conversion of fossil fuels to energy.  Ocean Health – Is there an “Acidification”  problem? concludes that CO2 is an important plankton food that enriches sea life, and that the term “ocean acidification” is highly misleading.

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
