"The skeptic attitude to consensus usually starts with “there is no consensus”. That’s wrong, and they usually retreat from it to “but consensus science is meaningless”, and/or “consensus has nothing to do with science”. The latter is largely true but irrelevant. The existence of the consensus doesn’t do a lot to determine what science is done; it doesn’t prevent contrary lines being explored. But the consensus view does come into the tricky interface between science and policy, and science and the media."

Also, I've been discussing the arguments all along, not sure what the reference to 'ad hominem' is about.
Here's the actual Wikipedia page: http://en.wikipedia.org/wiki/Scientific_opinion_on_climate_c...
It mentions: "No scientific body of national or international standing has maintained a dissenting opinion; the last was the American Association of Petroleum Geologists, which in 2007 updated its 1999 statement rejecting the likelihood of human influence on recent climate with its current non-committal position."
Maybe the American Association of Petroleum Geologists made that image you reference before changing their position. I don't know, it's completely out of context.
I'd agree- significant majority, but not a consensus right now.
Sorry, but there is a significant minority that in my mind prevents a consensus from existing. Majority is 84%, consensus is in the high 90s for me.
Take away vocal proponents, and you can clearly see that there is still room for debate here.
