I don't take the consensus of their opinions as "gospel truth". I take it as the consensus opinion of the experts in the field. Such a consensus - particularly one as close to unanimous as is AGW among active climate scientists - is more likely to be correct than any viewpoint that is NOT the consensus opinion of the experts in the field and far, far more likely to be correct than those contentions for which a consensus of falsehood exists among the experts in the field.
And I disagree with your statement regarding experts. You have made several conflicting statements. Experts today in any scientific field you can name, have greater and more accurate knowledge concerning their fields than did their predecessors. To say you can trust today's experts no more than those of the past is complete and utter nonsense.
