US Congress use Hollywood as scientific basis

There is always something weird cooking in the USA. This modern and progressive country is sometimes laughable, and also frightening, for the way it handles things. This time the congress is going to hear Michael Crichton on his scientific point of view on global warming and how humans may not be the cause. Just because this guy is a writer who decided to read on this subject make him a very important member of the scientific community. Or maybe that's the only one they found that could say that there is no such thing as a global warming induced by human activity. Nevertheless when the most powerful country ask a fiction writer for arguments against scientific work (same as for the evolution vs bible) I wonder how much we can trust these people...
