I read it recently. Frankly, it's not his best book but I thoroughly enjoyed his take on the environmentalists and their movement. I read it straight through because I was having so much fun reading about the enviro myths.
I have to say, none of this was news to me. I keep up with the global warming debate but it was great seeing Crichton put it all together in his book. He doesn't overwhelm you with the science but he does provide references for everything he says so you can pursue it in depth if you like. I would recommend it.
My take on the book, too.
Thanks, Arkie2 - Vacation reading it is.
