Michael Crichton, you know Andromeda Strain and Jurassic Park, was a physician, professor, and scientist. He wrote Andromeda Strain in medical school. His creds are quite impressive.
So, there is some reason in considering his speech on global warming. He doesn't much care about the state of the debate, his issue is with the complete lack of science upon which we are basing a completely disruptive public policy. I feel he sums things up pretty well with this statement:
"Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet,
because you're being had."
Here is the complete transcript. Definitely worth the read.

And almost like an intentional follow-on, have a read at this: Climategate - 30 years in the making
Then, back to Michael Crichton's speech on complexity theory - and why analysis that does not use methods for accounting for such systems (like Chaos Theory) are essentially bogus from the start.
