From an essay here at Edge219

My      first heresy says that all the fuss about global warming is grossly     exaggerated. Here I am opposing the holy brotherhood of climate model     experts and the crowd of deluded citizens who believe the numbers predicted     by the computer models. Of course, they say, I have no degree in meteorology     and I am therefore not qualified to speak. But I have studied the climate     models and I know what they can do. The models solve the equations     of fluid dynamics, and they do a very good job of describing the fluid     motions of the atmosphere and the oceans. They do a very poor job of     describing the clouds, the dust, the chemistry and the biology of fields     and farms and forests. They do not begin to describe the real world     that we live in. The real world is muddy and messy and full of things     that we do not yet understand. It is much easier for a scientist to     sit in an air-conditioned building and run computer models, than to     put on winter clothes and measure what is really happening outside     in the swamps and the clouds. That is why the climate model experts    end up believing their own models.

A must read for anyone concerned about the trend towards politically correct scientific research.
