Since the errors in IPCC AR3 were outed, there’s been this general view from the skeptical climate community at large and here on WUWT that the IPCC is collectively an elitist, pigheaded, organization, resistant to change. Recall ‘Voodoo Science’, as IPCC chair Rajenda Pauchauri once said in response to the Himalayan glaciers will melt by 2035 fiasco. I think I’ll let Dr. Roger Pielke Jr.’s example of this stand on its own without further comment:
Alleged errors in the treatment of disaster trends in Chapter 1, WGII, AR4
CLA response from Cynthia Rosenzweig and Gino Casassa
August 23, 2012
Alleged Error #1
Text from Roger Pielke, Jr.
Error #1: IPCC p. 110: “These previous national U.S. assessments, as well as those for normalised Cuban hurricane losses (Pielke et al., 2003), did not show any significant upward trend in losses over time, but this was before the remarkable hurricane losses of 2004 and 2005.”
FACTUALLY INCORRECT: Figure 5 in the following paper, in press prior to the IPCC AR4 WGII publication deadline, clearly shows that the addition of 2004 and 2005 losses do not alter the long-term trend in hurricane losses:
Pielke, Jr., R. A. (2006), Disasters, Death, and Destruction: Making Sense of Recent
Calamities. Oceanography 19 138-147.
This same information was also in the report of the 2006 Hohenkammer Workshop on Climate Change and Disaster Losses, which was cited by the AR4 WGII: http://cstpr.colorado.edu/sparc/research/projects/extreme_events/munich_workshop/pielke.pdf
RECOMMENDED CORRECTION: ““These previous national U.S. assessments, as well as those for normalised Cuban hurricane losses (Pielke et al., 2003), did not show any significant upward trend in losses over time, and this remains the case following the remarkable hurricane losses of 2004 and 2005.”
There is no error in the statement. No correction is needed and the text can stand as is.
The clause about the published analyses being before the 2004 and 2005 hurricane seasons is a statement of fact about the time line, and it is not a statement that the results were different after including 2004 and 2005. The statement does not infer that the overall pattern of losses would be different; instead it suggests that 2004 and 2005 were remarkable years in terms of hurricane losses, which they were.
PIELKE RESPONSE SEPTEMBER 13: This boggles the mind. The time line was such that published analyses (I provided 2!) that were available to the IPCC when drafting the AR4 included 2004 and 2005. The IPCC is say that up is down, and with a straight face. Did they not even read what I wrote?
