"Bunch of guys say don't panic over GW"
I think that's the nature of the debate in the US. One side tries to generate a panic in order to get anything done, and another side says 'Don't Panic' which is the same as 'do nothing'.
The rational course is to put a uniform tax on fuel, etc. The same with all this fracking, since it can't be good to inject billions of gallons of water into stressed faults. But the debate is always 'Let it alone', or 'Prohibition'.
