I have to agree that there appears to be some junk science in the global warming camp. Still, I’d like to see the US become a leader in clean energy. That will be a good worldwide market in the 21st century when the Chinese and Indians get tired of choking on car exhaust fumes. If the US sponsored a new “Apollo project” for clean and renewable energy, it could pay big dividends in the next few decades just like the original one did in the 60s and 70s (computers, aircraft technology, etc…).
And whether or not humans are causing it, the planet’s climate is changing, snowpacks are shrinking, and farms are struggling for lack of water in many areas; new technologies to help manage water supplies will also be in big demand.
