A really interesting post on cincinnatusblog.com entitled Climate Change – An Explosive Mixture of Science, Politics and Economics. It's really very good, in my opinion. The author reflects upon the scientific method as it applies to climatology, CO2 & water vapor as greenhouse gases, Global Warming & Politics/Economics, etc.
His concluding paragraph is very much in line with my thinking. There he lists an immediate need that we could actually remedy—all that TARP money could solve that problem now!
