Okay, if you have 1000 scientists and the bottom 80 percent think global warming is the warm and fuzzy trend and the top 20 percent thinks it's a hoax, you
could say there was a scientific consensus of sorts, but it would still be wrong.
Any idiot can follow, but it takes real guts to lead. My favorite quote was:
"It is a blatant lie put forth in the media that makes it seem there is only a fringe of scientists who don't buy into anthropogenic global warming." - U.S Government Atmospheric Scientist Stanley B. Goldenberg of the Hurricane Research Division of NOAA.
And in the scientific community, you cannot one day be for something and then the next day be against it without being labeled either wishy-washy or someone who doesn't fact check first (which leads to a serious credibility problem).
