What are you talking about Samwik? My link deals with the greenhouse effect of IR radiation. It is suggsted that if you increase the level of CO2 in a greenhouse, that the temperature would increase by slowing the rate at which IR can leave the structure. Similarly, if you keep the CO2 at the same level and only increase the amount of IR radiation, then the temp would still increase. The link I gave you disputes the second with respect to air, so logically it also disputes the first. That is not how greenhouses work.

Temperature is the measure of kinetic energy of atoms and molecules. Since IR does not contribute to to the temperature of air, it also does not contribute to the kinetic energy of molecules.
