This proposal leads to pure WP:OR. We categorize currently into very simple generic classifications based upon the quote. Alex' proposal is impossible, since, first of all we'd need to synthesize the scientists opinion, and the categories are simply contradictory between A&B;, climate sensitivity are just as important for solar, internal and cosmic rays, without a different approach to sensitivity none of the alternatives hold water. And furthermore Alex is assuming that the scientists view are internally consistent (ie. takes all data into account and explains them), which certainly isn't the case with several of the views that we have on the list. It could have been internally consistent for minority view, but won't be for tiny minority to fringe ones.
