The reason they use the term “settled science” is for one reason and one reason only. Because that is what Al Gore has consistently said about AGW, using the term as a cop-out to avoid debate with scientists who question AGW.

It’s his way of saying, “Those guys are on the fringe and not worth debating because the “science is settled.”

I can’t believe that the author doesn’t know this. Gore’s only been saying it for the last decade or so.
