From your link "the surface warming increases signicantly for the case of water feedback assuming xed relative humidity"
it literally explains the "Feedback Loop" that's the problem. CO2 causes some warming, which causes more H20 vapor to be released, which causes far more warming...and repeat.
a given CO2 concentration will obviously reach a heat/radiative equilibrium - but it's not acting alone.
Also, Venus would like a word.
