An excerpt for those without time to read it all
the issue is not Trenberth or scientists talking smack. It is the illegal evasion of legitmate scientific requests for data needed to replicate a scientific study. Without replication, science cannot move forwards. And when you only give data to friends of yours, and not to people who actually might take a critical look at it, you know what you end up with? A “consensus” …
Freedom of information, my okole…

People seem to be missing the real issue in the CRU emails. Gavin over at realclimate keeps distracting people by saying the issue is the scientists being nasty to each other, and what Trenberth said, and the Nature “trick”, and the like. Those are side trails. To me, the main issue is the frontal attack on the heart of science, which is transparency.
Science works by one person making a claim, and backing it up with the data and methods that they used to make the claim. Other scientists attack the work by (among other things) trying to replicate the first scientist’s work. If they can’t replicate it, it doesn’t stand. So blocking the FOIA allowed Phil Jones to claim that his temperature record (HadCRUT3) was valid science.
This is not just trivial gamesmanship, this is central to the very idea of scientific inquiry. This is an attack on the heart of science, by keeping people who disagree with you from ever checking your work and seeing if your math is correct.
