The argument is quite simple really.

We know that global warmings have occurred several times before the existence of Man. Even if we don't understand how or why, we know for certain that Nature can do it. Therefore, any argument about the causes of global warming must begin with the assumption that it is natural.

In order to argue that the Mankind is the cause, it must first be shown, beyond doubt, that Nature cannot be the cause. But since we don't understand the climate well enough to completely explain the natural variations, then we don't understand it well enough to prove that the current variations aren't natural. So the first essential hurdle has not been met.

Then there are the other problems:

Global warming has not occurred for ten years.
The predictions of greenhouse gas theory (rate of temperature increase in the tropical troposphere) are inconsistent with observations.

AGW fails on all fronts.

You got 1940$⁴ in the paragraph before figure 1. I read the html version. For some reason figures 3 and 4 did not appear on my first viewing, but they were there when I viewed it a second time to verify my memory.

That's my only complaint. It's the best original essay that I've read on this forum. You got great timing too in this winter of our discontent. Keep up the great work. I'm pinging everyone on my lists.

An excellent and concise explanation of the falacies of AGW. Outstanding.
