“It is error alone which needs the support of government. Truth can stand by itself. Subject opinion to coercion: whom will you make your inquisitors? Fallible men; men governed by bad passions, by private as well as public reasons. And why subject it to coercion? To produce uniformity. But is uniformity of opinion desireable? No more than of face and stature. Introduce the bed of Procrustes then, and as there is danger that the large men may beat the small, make us all of a size, by lopping the former and stretching the latter. “
-Thomas Jefferson
Thermodynamics says there will ultimately be a new equilibrium from increased heat absorbing gases (which come from physics). This might be 1 degree or so for a doubling of CO2. But science cannot say how long it will take to reach equilibrium nor the amount (if any) of added warming from increased H2O. The basic problem with the models is that they lack the resolution to model convection and the distribution of water vapor. Without knowing the distribution of water vapor (even versus uneven), it is impossible to know the amount of water vapor feedback. Observations in the real world suggest that it is negligible, and that weather acts as a damper on warming from other sources.
