More on Causes of Global Warming???

An interesting article in Newsweek.

Look at the credentials of the author, he's not some energy industry hack.

Lindzen is the Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology. His research has always been funded exclusively by the U.S. government. He receives no funding from any energy companies.

One great point among several:

Many of the most alarming studies rely on long-range predictions using inherently untrustworthy climate models, similar to those that cannot accurately forecast the weather a week from now.

I can speak from personal experience how difficult it is to have accurate models of complex systems. I have personally modeled thermal systems with 5 or 6 variables. I have seen the large impact a small mistake or bad assumption can have on the output. The climate has hundreds of variables, many of which scientists don't understand (like effect of water vapor in the air). It's impossible to to characterize a variable for a model if you don't understand it.

I hope nobody hurt themselves digging out from out April snow.

Also, was another book chosen and a date set for the next meeting. I was in Asia for the last meeting. What was the conclusion on Chomskey? Are we revoking his citizenship?
