"storage" means that it can be accessed at any time, despite the surrounding conditions.
Does CO2 store energy and retain it?
Did you just make-up that definition of storage? You can't IGNORE the "surrounding conditions" and I told you that in the last post.. HOWEVER -- it does not mean that CO2 can't absorb an IR Photon from the Earth's surface and SOME TIME LATER (not the 0.003 nsec you spewed) RE-EMIT it to the surface..
It might gain or lose energy in the INTERIM between absorption and emission due to kinetics, but it CAN act as a "mirror" for thermal energy in the IR band to be "reflected" back to the surface.. It's about 50% likely to send it to the sky direction and about 50% likely to send it back to Earth.. That's the GHouse effect....
End of discussion...
I lost track of the argument. Just what does the issue of CO2 storing or not storing energy have to do with atmospheric physics. If it is simply storage and release as in phase change, then it's a non issue because it doesn't happen.
The way I see it is that
above a few dozen meters, the equipartion principle keeps the vibrational states saturated (2/9 of the CO2 molecules are in the vibration state), and the atmosphere is in a local equilibrium.
Nearer the surface there is a constant IR influx that raises the percentage in the vibration state above 2/9 so that the atmosphere is not at equilibrium. As earth's surface IR continually creates new vibration states, collisions transfer that energy to the air molecules and raises the temperature near earth.
The percentage of elevated vibrations states is somewhat constant, but is a function of altitude because of the optical depth of 15 micron absorption. That creates a dynamic equilibrium.
Because of the absorption of earth's IR, the 15 micron IR intensity becomes exponentially less with altitude, there is a corresponding exponential drop in vibration percentage with altitude until a few dozen meters and the 2/9 percentage is reached and equilibrium occurs.
Storage doesn't enter this picture.
