I've always thought that the global warming disaster scenarios were the result of computer models going ballistic. I've written many physics simulations and they're only valid for a relatively short amount of time (iterations). Energy conservation has to be strictly enforced or you get runaway, etc.
That's right, but these guys don't care about that. It's their agenda they care about, not the physics of the situation. That's why their simulations include lots of bogus methods and data accompanied by as much handwaving. Like Bellisiles account of American history, or any leftist construction, reality doesn't matter. It's the desired outcome that does.
