Also missing is any realization that clouds also contribute to the greenhouse effect (roughly 25% of the total) and so whether cloud changes warm or cool depends very much on where the clouds are (high clouds have a very different effect than low clouds for instance).

That means the greenhouse substances are basically just CO2 and ozone, and they absorb in quite different parts of the spectrum. In the band of radiation where CO2 absorbs a lot (~15 $mu$m), increasing CO2 levels in the troposphere make it ever harder for those photons to get to the stratosphere or above.
