Example Of The Lack Of Due Diligence Of The IPCC As Has Been Reported By Benny Peiser At CCNet

Benny Peiser wrote the text below for the Daily Mail on January 18 2010 as reported on his e-mail list CCNet ( To subscribe send an e-mail to listserver [at] livjm.ac.uk).

“The IPCC review process has been shown on numerous occasions to lack transparency and due diligence. Its work is controlled by a tightly knit group of individuals who are completely convinced that they are right. As a result, conflicting data and evidence, even if published in peer reviewed journals, are regularly ignored, while exaggerated claims, even if contentious or not peer-reviewed, are often highlighted in IPCC reports. Not surprisingly, the IPCC has lost a lot of credibility in recent years. It is also losing the trust of more and more governments who are no longer following their advice – as the Copenhagen summit showed.’

To provide documentation on the failure of the 2007 WG1 IPCC report to provide due diligence in their climate assessment, I provided a list of peer reviewed papers in the appendix to my report

Pielke Sr., Roger A., 2008: A Broader View of the Role of Humans in the Climate System is Required In the Assessment of Costs and Benefits of Effective Climate Policy. Written Testimony for the Subcommittee on Energy and Air Quality of the Committee on Energy and Commerce Hearing “Climate Change: Costs of Inaction” – Honorable Rick Boucher, Chairman. June 26, 2008, Washington, DC., 52 pp

which were excluded from two chapters in the 2007 IPCC WG1 report.

I also posted on this issue in

Specifically, in Chapter 3 of the 2007 WG1 IPCC report which is titled “Observations: Surface and Atmospheric Climate Change”, the Coordinating Lead Authors were Kevin E. Trenberth (USA) and Philip D. Jones (UK), both of whom are, of course, involved in the CRU e-mails (e.g. see The Crutape Letters ). The Coordinating Lead Authors decided what was to be included in these chapters and what to exclude.

and in Chapter 8 of the 2007 WG1 IPCC report which is titled “Climate Models and Their Evaluation”, the Coordinating Lead Authors were David A. Randall (USA) and Richard A. Wood (UK).

The Coordinating Lead Authors in both chapters excluded available peer- reviewed papers which provide scientific evidence which conflicts with their conclusions in their chapters.

As the fall out from the CRU e-mails widens to include the IPCC reports, there is a need to assess and quantify the extent that these Coordinating Lead Authors (and those of other IPCC Chapters), excluded conflicting peer reviewed papers.  It is clear that in Chapters 3 and 8, this inappropriate behavior occurred with the result that a balanced scientific assessment of  climate observations and models was not achieved.
