Paul,
just fyi, the point about how 2/3 of the days heat comes from greenhouse (atmospheric) 'reheating,' while only 1/3 comes directly from the sun, is from measurements rather than theory.
Though that does include the nighttime, I suppose.
if you don't like my links , search it yourself.

has water vapor decreased
...well Paul, if that is what you search for,
then you'll certainly find some odd blogs (or media articles) repeating it.
What do your links say?
A hint, or a few quotes, would be nice.===
Try searching:

Can't change water vapor content directly: it responds to the global mean temperature
If your point is that we should better manage our GHGs,
to moderate the large feedback warming that water vapor contributes,
then I'd agree.
It is the very large 'absorption peak' (longwave) of CO2, which contributes to the greenhouse effect.
