cc: susan.solomon@noaa.gov date: Fri Feb 8 10:57:06 2008 from: Phil Jones subject: Re: IPCC Statements to: "Wayne P. Kraus" Wayne, I've given you starting points about the temperature data in a message recently sent. As for this one, I suggest again that you read the IPCC volume from the web site given previously. The quotes you have given here are a couple from the many in the SPM of the WG1 AR4 2007 Report. In the SPM volume each summary bullet refers to a section in the main report and/or the Technical Summary where you can find the background supporting information. For example, the first of your quotes refers to Chs 3,4 and 5. As I said in the earlier email, IPCC assesses the scientific literature. This literature has all appeared in peer-reviewed journals. I know the IPCC volume is large (996pp) but there is a lot of literature to assess from a lot of climatic-related fields. Best Regards Phil At 23:42 07/02/2008, you wrote: Professor Phil Jones: I have been researching some of your publications. I just ran across this information which I assume you have reviewed. The Inter-governmental Panel on Climate Change in its most recent report in 2007 stated: 'Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.' 'Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations12. This is an advance since the TAR's conclusion that "most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations". Discernible human influences now extend to other aspects of climate, including ocean warming, continental-average temperatures, temperature extremes and wind patterns' Please explain how you reconcile the fact that the present temperature increase began at the end of the last ice age and that the glaciers have been melting for tens of thousands of years with the claim that this is being driven by 20^th century production of greenhouse gases? How can present release of greenhouse gases be the cause of climate change that happened thousands of years ago? This conclusion seems entirely unjustified if only based on the actual geologic record of earth history. Have you had a peer review on this conclusion with the geological community? This conclusion seems completely illogical. Please do explain your conclusion!

We have been searching for the raw data from all historical temperature reporting stations used to construct the IPCC temperature plot. I guess this has become known as the hockey stick. We would like to do our own analysis of the raw data. We have lots of questions about the data you have used. Here are a few of the questions we have. 1. We have found the list of the 1221 USHCN stations from information posted by NCAR. We have noted that urban island effects began to influence the temperature readings during the flight to suburbia following WW II. Did you correct USHCN data to account for that bias? 2. Where can we find the raw data from historical temperature instruments covering the oceans? The oceans cover more than 70% of the surface of the earth and we expect that data to show significantly less variability (data scatter) than terrestrial temperature stations? 3. Where can we find the raw data for all historical temperature data outside the USA which you used when calculating your global average temperatures for the IPCC plot? 4. I anticipate the distribution of temperature recording instruments in remote and third world nations is more sparse than in western industrial nations. How did you adjust your global average volumetrically? What I mean is if there are 20 USHCN instruments covering the entire state of Kansas and 100 USHCN instruments in the densely populated area near New York City, the averaging technique has to remove that kind of bias. How did you do this? In short, I would be most grateful if you will direct me to an IPCC site where I can retrieve the entire raw data collection you used to develop your analysis. I would also like to see a comprehensive report on the techniques you used to compute your global average temperature used in your plot. Based on the many comments I have seen regarding your analysis of this recent temperature history, I believe this data and those conclusions require greater peer review than they have received. I hope you will cooperate in completing the scientific process of peer review and verification.
