"the cooling effect due to keeping incoming solar IR radiation away from the surface is about 100 times the re-heating effect proclaimed by greenhouse gas alarmists"
As also shown in Rescue from the Climate Saviors, CO2 and other IR-active gases do not act “like a blanket” but rather “like a sunshade”. They keep a part of the solar energy away from the earth’s surface. IR-active gases cool the earth: 70% of the entire cooling power originates from these molecules. Without these gases in the air, the surface and the air immediately above the ground would heat up more. The notion that a concentration increase of IR-active gases would impede earth’s cooling is impossible.

On Some Flaws in Greenhouse Gas Global Warming
Preface: I realized after writing this that I had forgotten to add a term for IR absorption by so-called greenhouse gases of the IR radiation which was reflected from the surface without being absorbed in the surface. This term is larger than that due to the radiation of IR due to the absorption of the solar radiation by the surface, but the sum of the two terms will still be smaller than the absorption by so-called greenhouse gases on the first pass through the atmosphere of incoming solar radiation. Also, please note that the incoming IR absorption process tends to deposit energy in the atmosphere at higher altitudes, while the outgoing absorption of IR by greenhouse gases deposits that energy closer to the ground. The discussion below is a simple attempt to see if adding IR-absorbing gases to the atmosphere tends to result in more or less warming of the surface. The most effective warming of the surface is that radiation first absorbed by the surface, rather than somewhere in the atmosphere. The remainder of this post is as it was earlier today posted and distributed.
I have just finished reading an excellent article by Alan Siddons called The Hidden Flaw in Greenhouse Theory on American Thinker from way back on 25 February 2010. The article is a little slow in developing, but finishes with a death blow to the usual theory put forth by catastrophic anthropogenic global warming advocates. I intend to explain more concisely what Siddons explained and to add comments of my own in this post which make the deathblow much more gory.
