As an aside, William Gray is a “Global Warming (tm)” skeptic.
I know that and respect him and his team (now headed by Klotzbach). The point remains that science builds theory that must be tested over and over for validity and if there is one falsification, it either must be explained and pass further testing or the theory loses credibility.
Meteorologists and climatologists KNOW that the Earth's atmosphere is just about the most difficult thing in current science to model. Remember the 'Chaos Theory' started with the idea that a butterfly at the right point and time in the Amazon could cause a typhoon half-way around the world. The most powerful computers outside the military are used to try to figure out where a tornado is going next and fails as frequently as not.
Yet these cultists believe with religious fever that they know both the cause and effect and that we need to impoverish generations to keep that deadly effect from our door.
