I'm pretty disillusioned with both sides of this debate at the moment, but I'm puzzled why nobody has produced much science- empirical or not- casting doubt on global warming. There's certainly many industries and governments that would benefit from that position, so you'd think if it could so easily be spun one way or the other, they would fund somebody to go out to do it.

Flipped around: If global warming advocacy is a racket, who's profiting from it? A bunch of green technology startups and carbon offset salespeople seem unlikely partners in a conspiracy, especially since most of them didn't exist when global warming started being played up as a problem.
