You may already have heard about novelist Michael Crichton's ill-advised foray into what he believes is serious scientific prediction, but sometimes this kind of silliness is worth revisiting. Crichton's latest novel, a highly fictional account of the current climate change debate, is called State of Fear. Though neither as readable nor as believable as Jurassic Park, this volume has won Crichton a surprising amount of time on the lecture circuit, where he has been peddling his imagined expertise in climate science.
The best counterpoints have come -- consistently, thoughtfully, reliably and even humorously -- from www.realclimate.org . But this post  is particularly fun, and it includes a brief but useful description of scientific method. Would that Crichton would read it.
