Living around Boulder you can't throw a stone without hitting someone that will engage you in a lively conversation about Global Warming. I count myself as a believer in all the data but fall a little short of being able to connect all the dots to global disaster. I believe the earth is a very complex climate that is not easily modeled. Don't get me wrong, ultimately the results may be far worst then being predicted, or maybe a good deal less. In either case I'm suspicious of the populations' ability to change anything that may or may not happen in a meaningful way even if we all wanted to, which we don't.
More interesting to me is Peak Oil Theory. There is a lot of good reading floating around on this not that new prediction that soon (if not already) the world production of oil will start to decline. Compounding the problem is the absolutely known fact that the world is using increasingly more oil, specifically in high growth economies like China. Obviously in today's gasoline climate you can start to see what happens when fuel is less and less available. I personally find this prophecy is much easier to connect the dots to an immediate global disaster then Global Warming. But, to each his own prediction of doom I suppose.
A friend of mine sent me a link to a just released asset management report.. It's very interesting reading and only a couple pages, check it out.
