Re: You do understand how peer review works, right?
That's only how they want you to THINK peer review works. The truth is something entirely different.
I worked as the DTP for a respected (in its field) scientific journal (closed at the time because open wasn't around then, not sure what it is today but I expect still closed since that was the second largest source of how the NPO behind it got its money, the first being its standards book used by an entire industry). Standard practice was for the author(s) of a paper to recommend at least three people to review the submitted paper. They were the people who typically reviewed the paper for technical accuracy. We had very few papers that weren't published after the author was able to respond to or incorporate criticism from the review. After the paper was peer reviewed it underwent an "English" review. Usually this was fine and it was the equivalent of a literary technical review. I do however recall one paper where the last "English" reviewer rewrote the whole paper with the author. The editor only realized what happened 30 days before the publication date. It was temporarily held, got a cursory secondary technical review and was published.
I have a friend with a Masters in Mathematics who has written papers. He frequently remarks that the fields are so narrow that you always know who the relevant people in your area are. And there is no way to hide who the actual reviewers are when you receive their reviews even though the names are removed. So you can't either freely criticize or freely defend your study, you always have to consider the political implications of what you write/say.
In short whether the system works as an honest quality control or a Politburo censorship board depends entirely on what the intentions of the reviewers are. And that fundamentally is the problem with the politicization of AGW/Climate Change is. Because the money holders and the leading researchers are working hand-in-hand while engaging in the name calling of Denialists for skeptics reviewing their work they are most likely working like a Politburo, not an honest review committee.
