Posted: 02/04/2009 - The claim that carbon dioxide (CO2) can increase air temperatures by “trapping” infrared radiation (IR) ignores the fact that in 1909 physicist R.W. Wood disproved the popular 19th Century thesis that greenhouses stayed warm by trapping IR. Unfortunately, many people who claim to be scientists are unaware of Wood’s experiment which was originally published in the Philosophical magazine , 1909, vol 17, p319-320. The experiment conclusively demonstrates that greenhouses heat up and stay warm by confining heated air rather than by trapping IR. If trapping IR in an enclosed space doesn’t cause higher air temperature than CO2 in the atmosphere cannot cause higher air temperatures. Trapping IR with CO2 would be like trying to confine mice with a chain link fence. Contrary to the lie repeated in news stories about climate, science doesn’t say that CO2 is causing higher temperatures by trapping IR. Empirical science indicates that no such process exists in this physical universe.
