It`s been said here that it`s simple physics:
It is simple physics. Here it is step by step.
- Black body radiation from the earth is absorbed by the GHGs in the atmosphere.
- That loss of EM energy to the atmosphere is random.
- Gain of random energy in a gas is thermal energy.
- That energy gain in the atmosphere must be equal to the EM energy loss.
- The conservation of energy requires the above.
As if it were as simple as that:

Abstract
Through the application of astrophysical formulas,the mean free path length of a Quantum/wave stream
leaving the surface of the Earth to the outer space before it has collided with a molecule of carbon dioxide
and its total emissivity are calculated. The output of this algorithm indicates a value of about 33 me
ters.Also calculated is the time taken by a Quantum/wave to exit the atmosphere after it has collided with
amolecule of carbon dioxide — which is 5 millisecond s (ms).
CONCLUSIONS:
The results obtained by experimentation coincide with the results obtained by applying astrophysics
formulas. Therefore, both methodologies are reliable to calculate the total emissivity/absorptivity of
any gas of any planetary atmosphere. At an average density, the atmospheric water vapor
allows quantum/waves to cross the troposphere to the tropopause in 0.004989 s, i.e.~5 milliseconds
. Through comparing the ability of water vapor to a void the quantum/waves to escape towards the outer space
with that of CO2 (0.004989 s), we can affirm that the role of CO2 on warming the atmosphere or the surface is impossible according to Physics Laws.
If we consider also that the carbon dioxide has by far a lower total absorptivity and total emissivity than water vapor, we fairly conclude that carbon dioxide is not a driver of climate changes or global warming on the planet Earth.
The low thermal diffusivity of carbon dioxide makes
of it to be an inefficient substance to adjust its temperature to that of its surroundings. Consequent
ly, the carbon dioxide can never reach the thermal equilibrium with respect to the remainder molecules
of the air. In consequence, carbon dioxide is not a greenhouse gas
