Leaving the Global Warming camp

"Vindication for skeptics":

One of the most decorated French geophysicists has converted from a believer in manmade catastrophic global warming to a climate skeptic. This latest defector from the global warming camp caps a year in which numerous scientific studies have bolstered the claims of climate skeptics. Scientific studies that debunk the dire predictions of human-caused global warming have continued to accumulate and many believe the new science is shattering the media-promoted scientific “consensus” on climate alarmism.

Claude Allegre, a former government official and an active member of France’s Socialist Party, wrote an editorial on September 21, 2006 in the French newspaper L'Express titled “The Snows of Kilimanjaro” (For English Translation, click here) detailing his newfound skepticism about manmade global warming. See here Allegre wrote that the “cause of climate change remains unknown” and pointed out that Kilimanjaro is not losing snow due to global warming, but to local land use and precipitation changes. Allegre also pointed out that studies show that Antarctic snowfall rate has been stable over the past 30 years and the continent is actually gaining ice.

Kilimanjaro, rising ocean levels, drowning polar bears, disappearing glaciers, and so forth -- if these are the best pieces of evidence being put forward for AGW, why don't they actually support the case?

Has anyone tested, e.g, a properly insulated column of well-mixed air with a black-body source of heat at the bottom and a method of injecting CO2  in order to see if adding more CO2 results in more warming of the column?  You'd have to focus the IR from the black-body source so that all the IR was traveling parallel to the sides of the structure (and not be absorbed by the sides).  And you'd have to have a transparent exit window for the IR to be radiated from the top of the structure.  And a way to measure the temperature of the column of air inside and assure a constant black-body IR output equivalent to that of the earth.

I have read in several places that all of the IR that can be absorbed by CO2 in the air is being absorbed right now and that adding more CO2 will not increase the temperature of the atmosphere at all.    So has anyone proved this experimentally?  If not, I would like to discuss funding such an experiment personally.  It seems that the prospect outlined in the first paragraph would be such an experiment.  What do you think?

Mike C. and I have been discussing this very topic (limits of CO2 greenhouse effect). Read this page for more info.

Testing. Ignore please.
