Doubly interesting is that Crichton was pretty much a liberal and supported Gore in the 2000 election. He believed that the measures Gore was advocating (carbon credits, lifestyle changes, et al.) would come about of their own accord. He opposed Gore's crusade because he thought Gore was pushing pseudo-science. Crichton believed that the bogus foundations of climate change science would eventually become known and work against Gore's political agenda.
Crichton expressed all these views during his appearance on the Charlie Rose show. You can see it at this link:
Charlie Rose - An hour with Michael CrichtonThe discussion turns to global warming about 25 minutes into the show. The look on Rose's face is priceless--he's incredulous that a right-thinking Al Gore supporter could doubt the truth of global warming!!
