Crichton's subject is today's fear that global warming will cause catastrophic climate change, a belief now so conventional that it seems to require no supporting data. Crichton's subject is also how conventional wisdom is manufactured in a credulous and media-drenched society.It reminded me of this speech that Chricton gave two years ago at CalTech, showing how global warming is being caused by aliens.
