97% consensus in the Peer Reviewed Literature that humans are causing climate change? I'm skeptical (of the science)

From the actual research (John Cook et al 2013 Environ. Res. Lett. 8 024024)

I don't know how you can say that this is a 97% consensus? I would say its a 32.6% consensus of the Climate Peer Reviewed Literature that humans are responsible (in at least some way) for Global Warming.   For mine, this  survey says more about the Research dollar. That of the politically inclined or politically financed climate research; 97.1% of that is pro AGW vs 2.9% going to anti-AGW. So much for all that money being spent by Oil Companies and Big Coal in funding think tanks and the like....not getting a great return on their investment.
