Global Warming? Don't Bet On It

On the probability of global warming:

So in the best case, the smartest climatologist in the world will know 100 variables, each one to an accuracy of 99 percent. Want to know what the probability of our spiffiest math model would be, if that perfect world existed? Have you ever multiplied (99/100) by itself 100 times? According to the Google calculator, it equals a little more than 36.6 percent.

The Bottom line: our best imaginable model has a total probability of one out of three. How many billions of dollars in Kyoto money are we going to spend on that chance?

Or should we just blow it at the dog races?

So all ye of global warming faith, rejoice in the ambiguity that real life presents to all of us. Neither planetary catastrophe nor paradise on earth are sure bets. Sorry about that. (Consider growing up, instead.)

That's why human-caused global warming is an hypothesis, not a fact. Anybody who says otherwise isn't doing science, but trying to sell you a bill of goods.

Probably.
