I wanted to repeat this because you have put some of my thoughts into words so well for me, thank you! I am not as sceptical of Global Warming as most here, but I do think it is silly to spend all that capital at this time on a problem we really aren't sure about. When and if the time comes, I believe we'll have the technology to "fix" the problem. Be it solar reflectors in orbit, or seeding the skys to increase reflective cloud cover. Not just that, but the US would be at the forefront of those efforts.
I just wanted to add one more point - any environmentalist that's really concerned about global warming and pollution should be pushing for the US to build as many nuclear power plants as possible to replace coal and oil fired plants. That would greatly reduce our greenhouse gas emissions, as well as having the nice side effect of increasing our energy independence.
Well, I think it's high time to resolve scientifically - and simultaneously - the following two problems: global pollution and Mohammedan threat.
If an economically viable technology to produce environmentally friendly fuel capable of replacing oil products was invented, Diaper Heads' wouldn't be able to hold the rest of the world to political ransom any more.
Having the US at the forefront of this task would be most fortunate.
