What property of CO2 allows it to heat the atmosphere beyond the heating it receives from the sun?

The ability of CO2 to absorb and emit infrared radiation while transmitting visible light.

since it has this amazing heating ability (by which it creates energy that wasn’t there

No one is claiming that CO2 creates energy that wasn't there.

Actually, the fluorescence of CO2 within the IR portion of the spectrum is absolutely meaningless. If you understand fluorescence, then you know that the wavelengths at which light is absorbed and reemitted are completely irrelevant, and the only relevant fact here is that the energy difference between the two wavelengths is emitted as heat (or IR). Since fluorescence occurring within any portion of the spectrum always produces a small amount of heat, the fact that it also does so within the IR portion of the spectrum is meaningless. All gases--indeed, all materials--have fluorescence spectra; therefore, the behavior of CO2 in this regard is indistinguishable from any other gas. In any case, no fluorescence occurs without an external energy source, and the heat produced is a tiny fraction of the total energy input.

If you take the proponents of human caused global warming at face value, then you have to conclude that they ARE saying that CO2 increases the total energy of the atmosphere. Otherwise, the only energy in the system is that which the sun provides; once that conclusion is reached, the whole idea that it is human caused becomes invalidated.
