Extreme Misrepresentation: USGCRP and the Case of Floods

Roger Pielke Jr.'s Blog
"Here I explain that in an area where I have expertise on, extremes and their impacts, the report is well out of step with the scientific literature, including the very literature it cites and conclusions of the IPCC. Questions should (but probably won't) be asked about how a major scientific assessment has apparently became captured as a tool of advocacy via misrepresentation of the scientific literature -- a phenomena tha occurs repeated in the area of extreme events. Yes, it is a draft and could be corrected, but a four-year effort by the nation’s top scientists should be expected to produce a public draft report of much higher quality than this. .......In no US region is there strong statistical evidence for flood magnitudes increasing with increasing CO2. This is precisely the opposite of the conclusion expressed in the draft report, which relies on Hirsch and Ryberg (2011) to express the opposite conclusion.
....However, given the problematic and well-documented treatment of extremes in earlier IPCC and US government reports, I'd think that the science community would have its act together by now and stop playing such games.
So while many advocates in science and the media shout "Alarm" and celebrate its depiction of extremes, another question we should be asking is, how is it that it got things so wrong? Either the IPCC and the scientific literature is in error, or the draft USGCRP assessment is -- But don't take my word for it, check it out for yourself.
