“IPCC AR4 also gets a failing grade on 21 chapters“. Anthony Watts wants you to know that Donna Laframboise (blogger) and a team of denialist “citizen auditors” have performed a grade school (literally) evaluation of the IPCC’s 2007 Assessment Report’s (“AR4”) references. The report, which Donna refers to as “the United Nations’ Nobel-winning climate bible“, gets an “F” for 21 of the 44 chapters, based on their personal assessment of the references.

“We’ve been told it’s 100 percent peer-reviewed science.” Um, no you haven’t. And the bulk of the claimed low-quality references are in the “Impacts” and “Mitigation” sections, not in the far more important “Climate Science” section.

Nothing is said about the physical science or historical evidence, of course. Funny how often “citizen” gets used as a descriptive badge among denialists.

Anthony finishes optimistically: people are beginning to laugh at the “robustness” oft touted in climate science. You’d better unplug your iPod, Anthony…

Oh Donna, you get an “F” too.
