From: Phil Jones To: John Christy Subject: This and that Date: Tue Jul 5 15:51:55 2005 John, There has been some email traffic in the last few days to a week - quite a bit really, only a small part about MSU. The main part has been one of your House subcommittees wanting Mike Mann and others and IPCC to respond on how they produced their reconstructions and how IPCC produced their report. In case you want to look at this see later in the email ! Also this load of rubbish ! This is from an Australian at BMRC (not Neville Nicholls). It began from the attached article. What an idiot. The scientific community would come down on me in no uncertain terms if I said the world had cooled from 1998. OK it has but it is only 7 years of data and it isn't statistically significant. The Australian also alerted me to this blogging ! I think this is the term ! Luckily I don't live in Australia. [1]http://mustelid.blogspot.com/2005/06/first-look-at-scs-msu-vn52.html Unlike the UK, the public in Australia is very very naïve about climate change, mostly because of our governments Kyoto stance, and because there is a proliferation of people with no climate knowledge at all that are prepared to do the gov bidding. Hence the general populace is at best confused, and at worst, antagonistic about climate change - for instance, at a recent rural meeting on drought, attended by politicians and around 2000 farmers, a Qld collegue - Dr Roger Stone - spoke about drought from a climatologist point of view, and suggested that climate change may be playing a role in Australias continuing drought+water problem. He was booed and heckled (and unfortunately some politicians applauded when this happened) - that's what we're dealing with due to columists such as the one I sent to you. Now to your email. I have seen the latest Mears and Wentz paper (to Science), but am not reviewing it, thank goodness. I am reviewing a couple of papers on extremes, so that I can refer to them in the chapter for AR4. Somewhat circular, but I kept to my usual standards. The Hadley Centre are working on the day/night issue with sondes, but there are a lot of problems as there are very few sites in the tropics with both and where both can be distinguished. My own view if that the sondes are overdoing the cooling wrt MSU4 in the lower stratosphere, and some of this likely (IPCC definition) affects the upper troposphere as well. Sondes are a mess and the fact you get agreement with some of them is miraculous. Have you looked at individual sondes, rather than averages - particularly tropical ones? LKS is good, but the RATPAC update less so. As for being on the latest VG analysis, Kostya wanted it to use the surface data. I thought the model comparisons were a useful aside, so agreed. Ben sent me a paper he's submitted with lots of model comparisons that I also thought a useful addition to the subject. As for resolving all this (as opposed to the dogfight) I'm hoping that CCSP will come up with something - a compromise. I might be naive in this respect. I hope you are still emailing and talking to Carl and Frank. How is CCSP going? Are you still on schedule for end of August for your open review? What will be interesting is to see how IPCC pans out, as we've been told we can't use any article that hasn't been submitted by May 31. This date isn't binding, but Aug 12 is a little more as this is when we must submit our next draft - the one everybody will be able to get access to and comment upon. The science isn't going to stop from now until AR4 comes out in early 2007, so we are going to have to add in relevant new and important papers. I hope it is up to us to decide what is important and new. So, unless you get something to me soon, it won't be in this version. It shouldn't matter though, as it will be ridiculous to keep later drafts without it. We will be open to criticism though with what we do add in subsequent drafts. Someone is going to check the final version and the Aug 12 draft. This is partly why I've sent you the rest of this email. IPCC, me and whoever will get accused of being political, whatever we do. As you know, I'm not political. If anything, I would like to see the climate change happen, so the science could be proved right, regardless of the consequences. This isn't being political, it is being selfish. Cheers Phil IPCC stuff ---- just for interest !!! IPCC ASKED TO COME CLEAN OVER CONTROVERSIAL HOCKEY STICK STUDIES The Committee on Energy and Commerce, 23 June 2005 [2]http://energycommerce.house.gov/108/Letters/062305_Pachauri.pdf Joe Barton, Chairman U.S. House of Representatives June 23, 2005 To: Dr. Rajendra K. Pachauri Chairman Intergovernmental Panel on Climate Change C/O IPCC Secretariat World Meteorological Organization 7 bis Avenue de La Paix C.P. 2300 Ch- 1211 Geneva 2 Switzerland Dear Chairman Pachauri: Questions have been raised, according to a February 14, 2005 article in The Wall Street Journal, about the significance of methodological flaws and data errors in studies by Dr. Michael Mann and co-authors of the historical record of temperatures and climate change. We understand that these studies of temperature proxies (tree rings, ice cores, corals, etc.) formed the basis for a new finding in the 2001 United Nation's Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR). This finding - that the increase in 20th century northern hemisphere temperatures is "likely to have been the largest of any century during the past 1,000 years" and that the "1990s was the warmest decade and 1998 the warmest year" - has since been referenced widely and has become a prominent feature of the public debate surrounding climate change policy. However, in recent peer-reviewed articles in Science, Geophysical Research Letters, Energy & Environment, among others, researchers question the results of this work. As these researchers find, based on the available information, the conclusions concerning temperature histories - and hence whether warming in the 20th century is actually unprecedented - cannot be supported by the Mann et. al. studies. In addition, we understand from the February 14 Journal and these other reports that researchers have failed to replicate the findings of these studies, in part because of problems with the underlying data and the calculations used to reach the conclusions. Questions have also been raised concerning the sharing and dissemination of the data and methods used to perform the studies. For example, according to the January 2005 Energy & Environment, the information necessary to replicate the analyses in the studies has not been made fully available to researchers upon request. The concerns surrounding these studies reflect upon the quality and transparency of federally funded research and of the IPCC review process - two matters of particular interest to the Committee. For example, one concern relates to whether IPCC review has been sufficiently robust and independent. We understand that Dr. Michael Mann, the lead author of the studies in question, was also a lead author of the IPCC chapter that assessed and reported this very same work, and that two co-authors of the studies were also contributing authors to the same chapter. Given the prominence these studies were accorded in the IPCC TAR, we seek to learn more about the facts and circumstances that led to acceptance and prominent use of this work in the IPCC TAR and to understand what this controversy indicates about the data quality of key IPCC studies. In light of the Committee's jurisdiction over energy policy and certain environmental issues in the U.S. House of Representatives, the Committee must have full and accurate information when considering matters relating to climate change policy. We open this review because the dispute surrounding these studies bears directly on important questions about the federally funded work upon which climate studies rely and the quality and transparency of analyses used to support the IPCC assessment process. With the IPCC currently working to produce a fourth assessment report, addressing questions of quality and transparency in the underlying analyses supporting that assessment, both scientific and economic, are of utmost importance if Congress is eventually going to make policy decisions drawing from this work. To assist us as we begin this review, and pursuant to Rules X and XI of the U.S. House of Representatives, please provide the following information requested below on or before July 11, 2005: 1. Explain the IPCC process for preparing and writing its assessment reports, including, but not limited to: (a) how referenced studies are reviewed and assessed by the relevant Working Group; (b) the steps taken by lead authors, reviewers, and others to ensure the data underlying the studies forming the basis for key findings - particularly proxy and temperature data - are accurate and up to date; and (c) the IPCC requirements governing the quality of data used in reports. 2. What specifically did IPCC do to check the quality of the Mann et. al. studies and underlying data, cited in the TAR? Did IPCC seek to ensure the studies could be replicated? 3. What is your position with regard to: (a) the recent challenges to the quality of the Mann et. al. data, (b) related questions surrounding the sharing of methods and research for others to test the validity of these studies, and (c) what this controversy indicates about the data quality of key IPCC studies? 4. What did IPCC do to ensure the quality of data for other prominent historical temperature or proxy studies cited in the IPCC, including the Folland et. al. and Jones et. al. studies that were sources for the graphic accompanying the Mann et. al. graphic in the Summary for Policy Makers? Are the data and methodologies for such works complete and available for other researchers to test and replicate? 5. Explain (a) the facts and circumstances by which Dr. Michael Mann served as a lead author of the very chapter that prominently featured his work and (b) by which his work became a finding and graphical feature of the TAR Summary for Policymakers. 6. Explain (a) how IPCC ensures objectivity and independence among section contributors and reviewers, (b) how they are chosen, and (c) how the chapters, summaries, and the full report are approved and what any such approval signifies about the quality and acceptance of particular research therein. 7. Identify the people who wrote and reviewed the historical temperature-record portions of the TAR, particularly Section 2.3, "Is the Recent Warming Unusual?" and explain all their roles in the preparation of the TAR, including, but not limited to, the specific roles in the writing and review process. 8. Given the questions about Mann et. al. data, has the Working Group I or the IPCC made any changes to specific procedures or policies, including policies for checking the quality of data, for the forthcoming Fourth Assessment Report? If so, explain in detail any such changes, and why they were made. 9. Does the IPCC or Working Group I have policies or procedures regarding the disclosure and dissemination of scientific data referenced in the reports? If so, explain in detail any such policies and what happens when they are violated. Thank you for your assistance. If you have any questions, please contact Peter Spencer of the Majority Committee staff at (202) 226-2424.
