The whole CAGW — GHG scare is based
on the obvious fallacy of putting the effect before the cause.As a simple (not exact) analogy controlling CO2 levels to control temperature is like trying to lower the temperature of an electric hot plate under a boiling pan of water by capturing and sequestering the steam coming off the top.A corollory to this idea is that the whole idea of a simple
climate sensitivity to CO2 is nonsense and the sensitivity equation has no physical meaning unless you already know what the natural controls
on energy inputs are already ie the extent of the natural
variability.
