The image above was created by National Science Board member James Lawrence Powell, who looked at 14,000 scientific papers on climate change. Which must have been a fairly mindboggling endeavor.
His goal was to test the oft-made climate-skeptic claim that there's still a debate among scientists as to whether man-made climate change is real. His result suggests there's no debate - just an overwhelming deluge of papers supporting the idea of man-made climate change.
Of course, the result might not prove climate science is real - it might just prove that scientists are conformists. But that's unlikely to be the case, since the world rewards controversial scientists much more than it celebrates conformists. Scientists get famous through breaking the mold - like Darwin and Einstein. So any scientist with good evidence against climate change would be likely to publish it ASAP, so as to win fame, notoriety, and hefty research grants.
