Science is not a democracy. There no such thing as science consensus, that is absolutely ridiculous and one more added to the fallacies around the issue. If all living things and the non-living things as well decide there is no gravity, we won't start floating just because 200% of the scientists or whatever got to a consensus that there is no such thing as gravity!
It only take one counter argument to debunk a theory. The defenders of the AGW cannot prove their argument (burden of the proof) and so use of fallacies (ad hominem arguments and others) to keep their farce. I don't know their reasons; but their "scientific" arguments has no ground!
