A very interesting post by Charles Battig, M.D., VA-Scientists and Engineers for Energy and Environment, at Wattsupwiththatdrawing attention to an important book by Julian Simon showing how a movement becomes blind to factual analysis and honest scholarship.
From Amazon: “Most people in the United States believe that our environment is getting dirtier, we are running out of natural resources, and population growth is a burden and a threat. These beliefs according to Simon, are entirely wrong. Why do the media report so much false bad news about these? And why do we believe it? Those are the questions distinguished scholar, Julian Simon set out to answer in this book.” click here

Classroom experiments that purport to demonstrate the role of carbon dioxide’s far-infrared absorption in global climate change are more subtle than is commonly appreciated. We show, using both experimental results and theoretical analysis, that one such experiment demonstrates an entirely different phenomenon: The greater density of carbon dioxide compared to air reduces heat transfer by suppressing convective mixing with the ambient air. Other related experiments are subject to similar concerns. Argon, which has a density close to that of carbon dioxide but no infrared absorption, provides a valuable experimental control for separating radiative from convective effects. A simple analytical model for estimating the magnitude of the radiative greenhouse effect is presented, and the effect is shown to be very small for most tabletop experiments.
