If global warming advocates are right what do they get? Gold star, notoriety for being great scientists, pat on the back and a gold watch? Even billions of dollars in research grants? Once they're right research money dries up, and you still have to fix the energy crisis that would ensue. And, big oil is handing out money left and right for any study saying the opposite. If funding were your only incentive you could just as easily get money from the other side. If you can prove global warming is or IS NOT caused by human activity you'll be very very famous, maybe rich.
Still that's paltry in comparison to the revenue of the oil, coal, and to some degree gas industries. I can't seem to make the the pay offs for being right equal out.
I like to not be so paranoid, but quite frankly this whole debate just seems like a smoke screen from both sides at the moment. Which could be yet another tactic since status quo benefits the CO2 producers.
