I apologize—I assumed your claim was that an increase of CO2 sufficient to directly cause a 1°C rise (about a doubling, is what I’ve heard) would make no more than 1°C rise. I objected because my current understanding is that the water vapor increases that to about 3°C rise.
If we have no disagreement on that point, we have no disagreement on anything that has been said denotatively so far. And, as we can both agree, any further remarks would be severely off-topic.

FWIW I do disagree with you on that point. But it was a different point from the one I was making.
I address the sensitivity issue in large part here:
