I'm not sure that peer review is of the utmost importance.
I came across this comment, which succinctly points out the flaws in the system.
Peer review certainly is flawed. Accepted wisdom once was that peptic ulcers were caused by lifestyle choices. Then a couple of Aussies wrote a paper claiming that peptic ulcers were caused by a bacteria called Helicobacter Pylori. Well...weren't they just pilloried and ridiculed. Until 20 years or so later when Drs. Marshall and Warren received the Nobel Prize for Medicine. Once the scholastics take hold of an idea, right or wrong, it is very, very difficult to loosen their grip. Unfortunately those self-same scholastics are going to be the ones reviewing all the papers that come their way. They are generally the people in the environment with the most to lose should their ideas be overthrown. So should someone actually think a new and peerless thought that thought is almost sure to be rejected precisely because it is new and peerless. Not because it may be incorrect but simply because no one has ever thought it before and there are no peers. The list of paradigm changing concepts that have suffered this fate throughout history is very long.

I am of course assuming that such reviews are carried out out by people expert in the same discipline who are also doing so with an open mind and with the best interests of the science at heart.
The worrying fact that so much reliance has been placed on these studies by governments eager to 'do something - anything', is disturbing to say the least.
Irrespective of this mess of confused findings - created largely by the scientists working these climate studies - there must be some review process of the results of this research, and who better to do it than other people expert in the field.
Such work must be checked before publication - especially when the stakes are so high.
