David also takes aim at Climate Audit's not being peer reviewed. I think this argument is completely overdone. Watson and Crick weren't peer reviewed. Einstein wasn't either. Didn't stop them being right.Well, Steve McIntyre isn't Einstein. Enough said.
Nor is he Crick or Watson. In any case, their work appeared in the best journals of their day (Annalen der Physik and Nature, respectively), and some rather distinguished editors approved of their publication there. (Peer review didn't become common until after WW2.) They didn't appear on a blog, nor where they accepted immediately. Or without the input from experts in the field.
It's important here to remember what science is and what it isn't. Blog posting aren't science. They don't look the same. They don't read the same. They have far different standards of scholarship. They have far different standards of publishing. It's kind of silly to even have to go into this, because there is no comparison.
And by the way, peer-review isn't an appeal to authority, so let's drop that canard. Nor does it say a paper is right. Plenty of peer-reviewed papers have turned out to be incorrect. As Robert Park says, passing peer-review means that a paper is not obviously wrong. And that it follows accepted methods of scholarship. These are important, and an important distinction. Of course, the only authority any scientific paper really has is its agreement with empirical data.
If Steve McIntyre really thinks he has an important point, then he should write up his findings and submit them to a journal. I'm sure he could collect the page charges from a tip jar. These days you can even ask that it be given express treatment.
