When deniers mention that GHG theory is entirely wrong and that, in fact increased CO2 cancels out the GHG properties of water vapour thus creating a natural balance you know they have latched on to Ferenc Miskolczi's theory. Other clues are the use of terms like 'black body' 'thermo dynamics' and various laws of physics. The usual argument goes something like this- [randomly trawled from the internet]
Anybody who thinks there is significant CO2 contribution to the GHE via atmospheric warming demonstrates extreme scientific ignorance. Firstly most of the surface IR emission in the CO2-GHG band is switched off. Secondly, CO2 self-absorbs from ~200 ppmv so its absorptivity plateaus [below the AGW point]. Thirdly, the Law of Equipartition of Energy at Local Thermodynamic Equilibrium coupled with Gibbs' Principle of Indistinguishability means that an incoming photon absorbed in a local volume cannot, as claimed by climate science, specifically Ramanathan, be converted to kinetic energy in the average time needed for it to be re-emitted.
This is the most childish of climate science's mistakes. Gibbs principle is that in a thermodynamic system, there is no memory. What really happens is that the concentration of activated CO2 molecules is set by the temperature through the bidirectional transfer of that energy to N2/O2 kinetic energy but is constant on average.
Therefore, the incoming photon energy is lost by an already thermally activated molecule instantly ejecting a similar photon out of that volume, restoring LTE. These peripatetic energy packets diffuse to heterogeneities such as clouds and bare aerosols to be thermalised, much into grey body radiation, to space or back to the surface. The atmospheric window grey IR from the tops of clouds is a cooling process.
blah blah blah....
You should practice what you preach and view the claims of
skeptics denialists with skepticism too instead of slurping it up like pablum.
