One of the immutable qualities of CO2 is that it is transparent to short-wave energy and opaque to long-wave. In other words, light will easily pass through it, bur heat is absorbed and reradiated.

In other words, CO2 causes absolutely no net change in energy, which is a necessary component of "global warming." In order for the atmospheric heat (energy) content to increase, CO2 would have to store energy, not absorb and release it almost instantaneously (via fluorescence).

You initial premise is faulty, i.e. a net change in energy being necessary. CO2 stores energy - as heat - that’s why it warms. There is no net change, only an energy transfer.
