All this mumbo jumbo about Arwheenieass, but no mention of any direct laboratory science, other than the peanut butter jar exibit?
The very high energy infrareds are the critical factor in this. Not the low energy frequncies of wavelength 10-15um that are important at earth's temperatures. Even the 15um band is actually outside the bulk of the distribution centered around 10um. The slope for the distribution is a square to the frequency at these low temperatures where hv is not much greater than kT.
So when did Boltzmaan determine the 'Gas Constant'? This applies uniformly to ALL GASES. There may be deviations in presssure and volume in the perfect gas law, but not the gas constant, R,
This energy of RT for molar value, determines the pressure of a gas.
Dividing the gas constant by Alvagardos's number gives the valaue of , k ,. Boltzman's constant which is the average knetic energy for 1 molecule of gas, at a given temperature.
NO DISTINCTION FOR CO2 OR ANY OTHER GASES
The only basis for defining co2 as polution, is that the words 'carbon dioxide', was includedin a list of products from combustion, in the 1970 Clean Air Act.
Althtough wormed back into science, after having been discarded by valid science and scientists, you stand now with NO SCIENCE to support the particular property of GHGs or anthropogenic global warming.
Hansen' s doctoral thesis of 1967, was that the higher than expected temperature at the surface of Venus, is caused by dust particles which block or trap microwaves.
In this thesis, he states directly that neither water vapor or co2 are important to the complete thermodynamic analysis he has supposedly achieved.
His thesis was not rejected by the theoretical science of the time, because this concept of specific reactivity of some gases to infrared, from pre-science, was rejected because of no supportive empirical science.
Those educated in higher education of any physical science at this time, never heard of greenhouse gases, within or without their field of specialty.
Methane exist at about 1 ppm,
Or about 1,500 parts per BILLION.
Methane oxidizes naturally in the atmosphere in 10-12yrs,
Therefore it does not accumulate.
If changes in methane of parts per 10 million or 100 million can affect atmospheric temperatures, this surely could be demonstrated in the laboratory, WHICH IT CANNOT.
