There's some extremely disturbing evidence that the three simultaneous "suicides" at Guantanamo actually died during a torture session and were subject to an ongoing coverup. Google News returns 367 hits for this subject. Nothing in the New York Times; Washington Post carried the AP news report.
A single paragraph in the 3,000 page International Panel on Climate Change report has been shown to be wrong, correctly stating that the Himalayan glaciers are melting but incorrectly stating that they will be gone by 2035. This claim was never highlighted or given much importance by the IPCC. Google News returns 1,789 hits on this mistake. Feel free to draw your own conclusions about the comparison of news report numbers.
Regarding the IPCC mistake, Tim Lambert, John Nielsen-Gannon, and William Connolley have written the most interesting stuff. I think Tim shows this was an unusual mistake that was almost caught in the draft review process - I find that somewhat reassuring as just a screwup instead of an accepted procedure. From William's comments though, the section of the IPCC dealing with impacts needs to improve its game.
My unsupported speculation is that the mistake is tied into some internal, office-politics conflict among Indian climate scientists, and that has something to do with the sloppy work in this particular instance.
