Heard about this on Bishop Hill's blog.
"This is the story of how I spent 2 years trying to publish a paper that refutes an important claim in the 2007 report of the Intergovernmental Panel on Climate Change (IPCC). The claim in question is not just wrong, but based on fabricated evidence. Showing that the claim is fabricated is easy: it suffices merely to quote the section of the report, since no supporting evidence is given. But unsupported guesses may turn out to be true. Showing the IPCC claim is also false took some mundane statistical work, but the results were clear. Once the numbers were crunched and the paper was written up, I began sending it to science journals. That is when the runaround began. Having published several against-the-flow papers in climatology journals I did not expect a smooth ride, but the process eventually became surreal."
