Interesting interview of Michael Crichton on Charlie Rose. He starts off talking about how he doesn't believe that it should be possible to patent genes. He might be correct, but I found is argument oversimplified. These letters to the editor do a good job explaining why it might be a good idea to keep the ability to patent them.
He then explains his position on global warming. I agree with lots of what he is saying. I think we need independent verification that the climate models can accurately predict the global temperature over the next 10 years before law makers unquestioningly use their predictions for policy. I also agree with him that a carbon tax is a good idea (although unlike him, I can't claim to have supported it for 25 years). And I also agree that overall Gore is a good guy, but his dire predictions of rising sea levels in an Inconvenient Truth are not what the mainstream climate scientists are predicting (at least not in the IPCC).
And if you want to see how Crichton's views have changed over time, check out all of his Charlie Rose interviews.
