Here is an interesting analysis of average earth temperature for the last 200 years. Despite the large increase in atmospheric CO2 concentration during the last 60 or 70 years, not much out of the ordinary has happened to average temperature. Al Gore wouldn't like that assessment, but it is true. Of course the warmists simply say that a lot of energy is being stored up somewhere, and that energy will soon be released like a spring, and temperature will soar. They have no proof, but it is also hard to prove them wrong. We'll have to wait to see if they are correct. But if Gore, Obama, and the UN get their way, they will destroy the economy of the United States and the Western world while we wait. Under their plan, they get to achieve their goal of a world-wide socialist government even if they are wrong.
