[Weird] Aliens Cause Global Warming

Nice text from Michael Crichton, in fact a lecture given at Caltech Michelin Lecture.

I am going to argue that extraterrestrials lie behind global warming. Or to speak more precisely, I will argue that a belief in extraterrestrials has paved the way, in a progression of steps, to a belief in global warming. Charting this progression of belief will be my task today.
