I was reading this post from Climate Quotes, wherein they demonstrate how the IPCC made a claim without proof, and when called on it, cast about for a source that turned out not to say any such thing. A lot of focus has been put on gray literature cited by the IPCC, but there appear to be at least as many occasions when the IPCC statement is not actually backed by the source cited.
The idea I had too late is that three years ago, when I had the time, I should have put the whole IPCC report on the web in some sort of Wiki or 2-column format (almost like a Medieval gloss) we could have linked and collected challenges to each individual statement and attribution. I think a couple of people are working towards this right now, but I kick myself for not thinking of it earlier. What a resource we would have now!
PS – No Consensus is looking for volunteers to identify and count the gray literature citations in the IPCC reports.
