Duke, are you denying that CO2 is in fact a greenhouse gas, in that it absorbs infrared radiation?


Nope, not at all. Can you prove that CO2 (an essential trace gas naturally found in the atmosphere--at far less than 1%) in its tiny concentration has any perceptable effect on the atmospheric temperature? Bear in mind--the mere fact that a tiny fraction of a percentage exists and a belief in GW are proof of nothing at beyond the ambient CO2 level and the possession of a belief.

The "free atmosphere" of Mars seems to be primarily CO2, is it causing wild uncintrolled heating of the Martian climate?

Char, about 99% of our atmosphere is nitrogen, oxygen, and argon--a fraction of the remainder is CO2. Can you point to "blind experimental studies" proving that such a minute amount of CO2 in an environment with high water content will cause unrestricted warming? I can envision several ways to set up such an experiment with two comparable environments--one free of CO2 and the other with a minute amount present.
President Reagan summed it up nicely, "Some people go through their entire lives wondering if they made a difference, Marines don't have that problem!!!"
