On Climate Sensitivity

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 one of America’s most distinguished atmospheric physicists, MIT emeritus Alfred P. Sloan professor of meteorology Richard S. Lindzen.

Professor Lindzen has published over 200 scientific articles and books over a five-decade career. He has held professorships at the University of Chicago, Harvard University and MIT. He is a member of the National Academy of Science, the Norwegian Academy of Science and Letters, and the American Academy of Arts and Sciences. He is a fellow and award recipient of the American Meteorological Society and the American Geophysical Union.  He is also a fellow of the American Association for the Advancement of Science, and was a lead author of the UN IPCC’s third assessment report’s scientific volume.

Since 1988, much of Professor Lindzen’s research has highlighted the scientific uncertainties about the impact of carbon dioxide emissions on temperature. He has published frequently on the crucial and uncertain impact of clouds on temperature “feedbacks” – processes which cause substantial hypothesized magnification of CO2-based warming in the models used by the IPCC.

Providing review assistance to Professor Lindzen for this paper was another distinguished atmospheric climatologist, Dr. Roy W. Spencer. Dr. Spencer is one of the primary inventors of the remarkable scientific enterprise of “remote sensing” of temperature, humidity, and other properties crucial to climate by satellites.  At his research professorship at the University of Alabama in Huntsville, he is both generator and guardian of satellite data relied upon by scientists and governmental bodies throughout the world.

Pennsylvania’s Regional Greenhouse Gas Initiative Relies on Faulty Data – Why RGGI is a “solution in search of a problem”

The Governor and other officials have relied heavily on the state’s Climate Action Plans and specifically on the 2018 Pennsylvania Climate Action Plan3 in order to support their claims of current and future devastating impacts of continued CO2-driven warming. Assertions in the Climate Action Plan are refuted by the analysis of Gregory Wrightstone, Executive Director of the CO2 Coalition and an expert reviewer for the U.N. Intergovernmental Panel on Climate Change’s 6th Assessment Report (IPCC – AR6). 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
