John - you wrote: "Although I'm a geoscientist with a PhD from Caltech, I would never take this approach unless there were disagreement among the experts."

Is that perhaps a misstatement of your position? My own take on the subject is that we are well-served by taking the opinion of the vast majority of scientists with qualifications in the field. In this particular matter, there is only middling disagreement among the experts. You might possibly have meant to state that you wouldn't take this approach unless there was strong agreement [not "disagreement"] among the experts.
