Modern climate science's fundamental premise (or assumption) is that the greenhouse gases (around 2% of the atmosphere) absorb radiant infrared (IR) heat (as derived by IR spectroscopy), and are a main climate driver because of this specialty. This premise has its origins with the John Tyndall 1859 thermopile infrared detection experiment. The (other) non-greenhouse gases (N2 nitrogen and O2 oxygen) are distinguished from the greenhouse gases by their (said*) inability to absorb (infrared) heat, as deduced from the same experiment: here absorption is confused with opacity. Raman spectroscopy (a complement to IR spectroscopy) challenges this greenhouse gas non greenhouse gas paradigm, and reveals this assumption and conclusion from any IR spectroscopy measurement to be false. It can be shown that N2 and O2 are, due to their symmetric vibration totally transparent to all IR detectors, but are not transparent to Raman detectors. Ramon Spectroscopy shows: CO2 and the other greenhouse gases to be typical, and not special; and that N2 and O2 to be greenhouse gases. Further claims are also challenged with respect to CO2 special properties in this entry. The only valid co-efficient or method to measure a gases heat absorption is by Specific Heat Capacity: where CO2 is a poor contender.
