Rigging the rules of climate from the beginning

Has this all been rigged from the beginning? [Link]

As anonymous reviewers of choice for certain journals, Mr. Mann & Co. had considerable power to enforce the consensus, but it was not absolute, as they discovered in 2003. Mr. Mann noted to several colleagues in an email from March 2003, when the journal "Climate Research" published a paper not to Mr. Mann's liking, that "This was the danger of always criticising the skeptics for not publishing in the 'peer-reviewed literature'. Obviously, they found a solution to that—take over a journal!"
The scare quotes around "peer-reviewed literature," by the way, are Mr. Mann's. He went on in the email to suggest that the journal itself be blackballed: "Perhaps we should encourage our colleagues in the climate research community to no longer submit to, or cite papers in, this journal. We would also need to consider what we tell or request of our more reasonable colleagues who currently sit on the editorial board." In other words, keep dissent out of the respected journals. When that fails, re-define what constitutes a respected journal to exclude any that publish inconvenient views. It's easy to manufacture a scientific consensus when you get to decide what counts as science.
The response to this among the defenders of Mr. Mann and his circle has been that even if they did disparage doubters and exclude contrary points of view, theirs is still the best climate science we've got. The proof for this is circular. It's the best, we're told, because it's the most-published and most-cited—in that same peer-reviewed literature.
Even so, by rigging the rules, they've made it impossible to know how good it really is. And then, one is left to wonder why they felt the need to rig the game in the first place, if their science is as robust as they claim. If there's an innocent explanation for that, we'd love to hear it.
