Radiation physics constraints on global warming: CO2 increase has little effect

Radiation physics constraints on global warming: CO2 increase has little effect By Denis G. Rancourt Former physics professor, University of Ottawa, Ottawa, Canada. Posted on June 3, 2011: http://climateguy.blogspot.com/2011/06/radiation-physics-constraints-on-global.html A new pdf file was uploaded here to archive.org on December 3, 2011, with small clarifications added and typos corrected. The corrected December 3, 2011, pdf file has a note to this effect in the header on page-1. A detailed peer-review of this article is available here: http://climateguy.blogspot.com/2012/01/ray-pierrehumberts-peer-review-of.html ABSTRACT -- I describe the basic physics of planetary radiation balance and surface temperature, using the simplest model possible that is sufficiently realistic for correct evaluations of predicted surface temperature response sensitivities to the key Earth parameters. The model is constrained by satellite absolute integrated intensity and spectroscopic measurements and the known longwave absorption cross section of CO2 gas. I show the predicted Earth temperature for zero atmospheric resonant absorption of longwave radiation (no greenhouse effect in the otherwise identi
