Another Example Of Inappropriate Communications On A Climate Assessement

Climate Etc. at 2

there is a remarkable e-mail that Steven Mosher posted September 1, 2012 at 11:12 pm from those hacked from the University of East Anglia (i. e. what has been called “Climategate”).  Steven’s comment is presented below followed by my comment as to why this is significant [highlight added]

From: Phil Jones To: “Michael E. Mann” Subject: Empire Strikes Back – return of proper science ! Date: Fri May 20 13:45:26 2005


REDACTEDJust reviewed Caspar’s paper with Wahl for Climatic Change. Looks pretty good. Almost reproduced your series and shows where MM have gone wrong. Should keep them quiet for a while. Also they release all the data and the R software. Presume you know all about this. Should make Keith’s life in Ch 6 easy ! Also, confidentially for a few weeks, Christy and Spencer have admitted at the Chicago CCSP meeting that their 2LT record is wrong !! They used the wrong sign for the diurnal correction ! Series now warms – not quite as much as the surface but within error bands. Between you and me, we’ll be going with RSS in Ch 3 and there will be no discrepancy with the surface and the models. Should make Ch 3 a doddle now ! Keep quiet about this until Bern at least. Can tell you more then. RSS (Carl Mears and Frank Wentz) found the mistake ! The skeptic pillars are tumbling ! Cheers Phil

I was at the Chicago meeting.  First the error that is mentioned in Phil Jones was actually  a minor one, and was corrected by Spencer and Christy immediately after it was identified at the meeting by the RSS group (Wentz and Mears). I felt it was odd that the RSS group presented this at the meeting rather than communicating prior to the meeting.

What is most disturbing, however, is that Phil Jones (who was NOT a member of the CCSP 1.1 Committee) found out about this issue, when the meetings of our Committee were supposed to be confidential.  Then, Phil Jones disseminated this information further to Mike Mann.

This is yet another example of the Old Boy’s network that, in my view, has undercut the credibility of climate assessments.

See also my posts (of which several provide additional examples of the inappropriate communication of Committee information to others outside of the Committee).

It has been over 7 years since the e-mail was sent by Phil Jones to Michael Mann. Unfortunately, it appears nothing has actually changed with respect to the Old Boy’s network.

Comment On The Article “Ad Hominem Arguments In The Service Of Boundary Work Among Climate Scientists” By Souder and Qureshi 2012

Judy Curry mentioned this article from BishopHill

Ad hominem arguments in the service of boundary work among climate scientists

by Lawrence Souder and Furrah Qureshi of Drexel University in the journal Journal of Science Communication 11(1), January 2012

in her post

Week in review 3/16/12

The Souder and Qureshi article uses quite a bit of jargon but it is worth reading. Here I want to just add to one of the examples presented in the Souder and Qureshi 2012 paper

In the header to the article, the authors identified one ad hominem comment about me; i.e.

“Pielke wouldn’t understand independence if it hit him in the face.” (Phil Jones, Climategate email, 1233249393.txt)

where “independence” is referring to the degree of overlap in the land surface temperature data used to construct the CRU, GISS and NCDC global surface temperature trend analyses.

The Souder and Qureshi article  has the introductory paragraph

“As scientists-in-training, Chris de Freitas and Roger Pielke, Sr., may have suffered appropriately the sting of such remarks from an overbearing advisor on their dissertation committees in a moment of impatience. However, once these scientists were certified by their authorizing institutions, they should no longer fear such ad hominem attacks. If science proceeds as a matter of empiricism, the first and only point of judgment should be the validity of the inquiry, not the character of the inquirer. In fact, when peer review is blinded, the resulting anonymity is intended to preclude personal attacks. Thus is one of the key norms of science enforced — disinterestedness. On the assumption that de Freitas and Pielke would not reasonably expect to hear such personal attacks in a public forum their private expression is at least disturbing for their revelation of the tone of some scientists’ discourse.”

In addition to this conclusion by Souder and Qureshi, Phil Jones’s comment is also disingenuous as well as being ad hominem. While I was on the CCSP 1.1 Committee, I contacted Phil to ask the degree of independence between his data set (CRU) and those of GISS and NCDC. He responded at the time and I later included this information in our paper

Pielke Sr., R.A., C. Davey, D. Niyogi, S. Fall, J. Steinweg-Woods, K. Hubbard, X. Lin, M. Cai, Y.-K. Lim, H. Li, J. Nielsen-Gammon, K. Gallo, R. Hale, R. Mahmood, S. Foster, R.T. McNider, and P. Blanken, 2007: Unresolved issues with   the assessment of multi-decadal global land surface temperature trends. J. Geophys. Res., 112, D24S08, doi:10.1029/2006JD008229

where we reported from Phil Jones that

“The raw surface temperature data from which all of the different global surface temperature trend analyses are derived are essentially the same. The best estimate that has been reported is that 90–95% of the raw data in each of the analyses is the same (P. Jones, personal communication, 2003).”

Phil Jones, of course, made his comment

“Pielke wouldn’t understand independence if it hit him in the face.”

in January 2009!

He chose not to remember that he actually answered my question on “independence” 6 years earlier. Instead he decided to make an ad hominem comment since, even though he was misrepresenting reality, the comment was made behind my back and would never have been seen by all of us except for the Climategate e-mails. Unfortunately, this is quite likely just a sample of what has been communicated by some of the major players in the IPCC community [and still continues].

Further Evidence Of The Failure Of Multi-Decadal Regional Climate Predictions To By Of Value To The Impacts Communities

In response to the post on Watts Up With That on March 12 2012 titled

Climate modeling turkey shoot, western style

Dr. Nathan Schmidt, a Senior Water Resources Engineer at Golder Associates Ltd in Edmonton, Alberta alerted me to a very enlightening e-mail that was exposed in one of the Climategate e-mails.

The e-mail is from Jagadish Shukla of COLA with respect to the IPCC report. Dr. Shukla is an internationally well-respected climate scientist. The e-mail reads [highlight added]

date: Wed, 13 Feb 2008 16:46:33 -0500 from: J Shukla subject: Future of the IPCC: to: IPCC-Sec

Dear All,

I would like to respond to some of the items in the attached text on issues etc. in particular to the statement in the section 3.1.1 (sections 3: Drivers of required change in the future).

“There is now greater demand for a higher level of policy relevance in the work of IPCC, which could provide policymakers a robust scientific basis for action”.

1. While it is true that a vast majority of the public and the policymakers have accepted the reality of human influence on climate change (in fact many of us were arguing for stronger language with a higher level of confidence at the last meetings of the LAs), how confident are we about the projected regional climate changes?

I would like to submit that the current climate models have such large errors in simulating the statistics of regional (climate) that we are not ready to provide policymakers a robust scientific basis for “action” at regional scale. I am not referring to mitigation, I am strictly referring to science based adaptation.

For example, we can not advise the policymakers about re-building the city of New Orleans – or more generally about the habitability of the Gulf-Coast – using climate models which have serious deficiencies in simulating the strength, frequency and tracks of hurricanes.

We will serve society better by enhancing our efforts on improving our models so that they can simulate the statistics of regional climate fluctuations; for example: tropical (monsoon depressions, easterly waves, hurricanes, typhoons, Madden-Julian oscillations) and extratropical (storms, blocking) systems in the atmosphere; tropical instability waves, energetic eddies, upwelling zones in the oceans; floods and droughts on the land; and various manifestations (ENSO, monsoons, decadal variations, etc.) of the coupled ocean-land-atmosphere processes.

It is inconceivable that policymakers will be willing to make billion-and trillion-dollar decisions for adaptation to the projected regional climate change based on models that do not even describe and simulate the processes that are the building blocks of climate variability. Of course, even a hypothetical, perfect model does not guarantee accurate prediction of the future regional climate, but at the very least, our suggestion for action will be based on the best possible science.

It is urgently required that the climate modeling community arrive at a consensus on the required accuracy of the climate models to meet the “greater demand for a higher level of policy relevance”.

2. Is “model democracy” a valid scientific method? The “I” in the IPCC desires that all models submitted by all governments be considered equally probable. This should be thoroughly discussed, because it may have serious implications for regional adaptation strategies. AR4 has shown that model fidelity and model sensitivity are related. The models used for IPCC assessments should be evaluated using a consensus metric.

3. Does dynamical downscaling for regional climate change provide a robust scientific basis for action?

Is there a consensus in the climate modeling community on the validity of regional climate prediction by dynamical downscaling? A large number of dynamical downscaling efforts are underway worldwide. This is not necessarily because it is meaningful to do it, but simply because it is possible to do it. It is not without precedent that quite deficient climate models are used by large communities simply because it is convenient to use them. It is self-evident that if a coarse resolution IPCC model does not correctly capture the large-scale mean and transient response, a high-resolution regional model, forced by the lateral boundary conditions from the coarse model, can not improve the response. Considering the important role of multi-scale interactions and feedbacks in the climate system, it is essential that the IPCC-class global models themselves be run at sufficiently high resolution.

Regards, Shukla

This e-mail further illustrates what I discussed yesterday in my post

Climate Science Malpractice – The Promotion Of Multi-Decadal Regional Climate Model Projections As Skillful

Those who present multi-decadal regional climate model results to the impact (stakeholder) community without also communicating that they have no predictive skill (or provide evidence to the contrary) are quilty of climate science malpractice.

What Climategate 2.0 Says About The Prediction Of Multi-Decadal Regional Climate Change

Marcel Crok has alerted us to the post by Maurizio Morabito titled

On The Slow, Painful (and Deadly) Demise Of The IPCC

at the weblog The Unbearable Nakedness of Climate Change

Their post involves the discussion of the predictive skill of multi-decadal regional climate change. It is essential to recall that the climate models must not only be able to skillfully predict current climate statistics but also how these statistics would change due to the human intervention of the climate system.

Vast amounts of money are being spent (and wasted) claiming that such multi-decadal climate change predictions are accurate and can be used by the impacts community. See, for example, my recent post

The Huge Waste Of Research Money In Providing Multi-Decadal Climate Projections For The New IPCC Report

Misleading Climate Science – An Example Of Multi-Decadal Regional Climate Predictions With No Demonstrated Skill On That Time Scale

I have reproduced  On The Slow, Painful (and Deadly) Demise Of The IPCC post below, including retaining the highlighted text.

Climategate 2.0 is helping filling some knowledge gaps, for example in the way the IPCC has been slowing killing itself, and several thousands humans to. The following concerns Regional Projections, and it’s a tragedy of communication.

Willingly or not, the IPCC has become a source of deadly confusion exactly because it has provided the information its audience wanted, even if it was scientifically unprepared to prepare that information.

It’s the year 2000 and the IPCC Third Assessment Report (TAR) is being prepared. As we can see in file 0598.txt, there is a frank exchange of opinions about WG1-Chapter 10 “Regional Climate Information – Evaluation and Projections”, between Filippo Giorgi (Coordinating Lead Author), Hans Von Storch (Lead Author), Jens H. Christensen (Lead Author) (my emphasis of course):


Under the “encouragement” of Sir John, we also decided to add a text box on what we can say about regional climate change over different continents. This will probably be the most-read part of the chapter, so we need to be very careful with it. I and Peter will produce a draft to circulate. I know that originally we did not want to do this, but this is what they are asking us to do and it is now very clear that it is the main purpose of the chapter, so we have to do it.

Von Storch:

First, I don’t think that John Houghton is particularly qualified in saying anything about regional assessments. So far as I know he has no relevant official capacity in the process,and he has not been particularly helpful in SAR. Actually, I consider him a politically interested activist and not as a scientist.[…] I do not agree [about adding the text box]. What were the arguments we originally did not want to do this? What are the new arguments overriding our previous concerns? I am sure that people would love to read this statement in New York Times. We don’t feel confident to make a statement, and then, suddenly, under the encouragement of Sir John, we include it? This is truly embarrassing. If the purpose of the Chapter is to produce statements on regions, and we found we can not do that, what should the assessment be? Simply: “We can not do it at this time, but we have a variety of techniques to derive scenarios. However, for various reasons, we can not say that they are consistent, even if there is some convergence.”


This is an important point […] In my eyes Sir John represents the typical reader of this report and if he made that comment and “encouragement” it means that our chapter is not sending the proper message (after all he is one of the chairs of IPCC WGI). You may remember that I was always of the opinion that we were talking too much about techniques and too little about climate change. Now I think that we need to change that to the extent possible: reduce technical issues, increase climate change information. We actually already have a lot of that information in there, especially in the AOGCM part. What Sir John asked was to make it more “legible”, and we decided in Auckland to make it in the form of a box. We cannot invent information of course, but we can condense it in this box by including 1) the info relative to what AOGCMs sy for different continent, which is already there; 2) all possible other info from the techniques. If there is none or if we can say nothing we’ll say we cannot do it for that specific region. but I think we need to do something because the way it is, the chapter does not address the right audience, which is not only made up only of scientists.



I just want to add my opinion on this. I do agree with the point that we have to offer the regional information available. By setting up the box with the regions, we will provide the obvious assessment over many regions, which Hans has put forward so simple: The quality of the global models are too poor to give any clear information about regional climate change. We can state for the various regions, where there is some information, to what extend there is agreement between models etc. However, even agreement amongst models does not at this stage allow for any thorough assessment about uncertainties about changes. This must come out crystal clear, even if this will be the message for all regions! At least we will make out point about assessing regional climate change very clear this way.

Months later, the report comes out. Houghton’s text box has become “Box 10.1: Regional climate change in AOGCMs which use SRES emission scenarios” (page 600 here). Caveats are in place:

Introduction This box summarises results on regional climate change obtained from a set of nine AOGCM simulations undertaken using SRES preliminary marker emission scenarios A2 and B2. […].These results should be treated as preliminary only.

However, Christensen’s cautionary suggestion is totally reversed, and agreement among models is seen as a measure of certainty of changes “relatively speaking”:

Agreement across the different scenarios and climate models suggests, relatively speaking, less uncertainty about the nature of regional climate change than where there is disagreement

It’s now 2007. The equivalent chapter is AR4 WG 1-Chapter 11 “Regional Climate Projections“. Christensen is now a Coordinating Lead Author, Giorgi a Review Editor. And what has happened to the chapter?

  1. The “Summary of the Third Assessment Report” is mostly a summary of Box 10.1 described above. Everything else has been thrown in the classical bin
  2. The whole chapter in 2007 is actually a giant version of Box 10.1 in 2003
  3. Amazingly (and unscientifically) we’re being spoken of some “robust findings on regional climate change for mean and extreme precipitation, drought and snow”
Giorgi’s “target” has been achieved. The “most read part in the chapter” has become the whole chapter. A description of the current knowledge has become less important than providing what people asked. The audience has won, and the science has lost.
Then it gets worse.
Even in 2007, regional changes described by the IPCC are for the 2080-2099. Captions are very explicit on the subject. For example look IPCC AR4 WG1 report, section 11.2  about Africa. In particular, figure 11-2 is about “Temperature and precipitation changes over Africa from the MMD-A1B simulations“. Both in the text and in the caption, the projected time period of 2080-2099 is clearly indicated.
In 2011 however, Chris Funk feels compelled to write a column for Nature, published on Aug 3 as “We thought trouble was coming“, describing “how his group last year forecast the drought in Somalia that is now turning into famine — and how that warning wasn’t enough” and in particular lamenting that
The global climate models used by the Intergovernmental Panel on Climate Change were never intended to provide rainfall trend projections for every region. These models say that East Africa will become wetter, yet observations show substantial declines in spring rainfall in recent years. Despite this, several agencies are building long-term plans on the basis of the forecast of wetter conditions..

Those agencies might have foolishly misunderstood the IPCC message. Perhaps, they believe too much in it, missing therefore the small print indicating wetter conditions are expected 70 years since.

And so we have gone full circle. Originally provided by scientists ready to stretch the science on the “encouragement” by Sir John Houghton, in the space of a single decade Regional Projections have gone on to become an unwittingly deadly tool.

As added information, I was invited to serve as one of the contributing authors of the regional modeling part of the 1995 IPCC report [of which Fillipo Giorgi was also involved with]. I resigned from the IPCC as documented in the letter below (see also my post on this letter)

The erroneous IPCC presentation of multi-decadal regional climate prediction skill continues today (2011).  The views I expressed in the letter are further bolstered by these Climategate 2.0 e-mails.

Significance Of Climategate #2 – Further Evidence Of The Failure Of An Appropriate and Accurate Assessment Of Climate Science

There have been media articles that dismiss the importance of the Climategate #2 e-mails; e.g. see.

These Climategate e-mails, however, are just the “tip of the iceberg” which we were only able to see because this source of information was hacked.

I  provide further documentation of this “old boys” network in the post

Climate Assessment Oligarchy – The IPCC.

In that post I wrote

An oligarchy is a

“form of government in which all power is vested in a few persons or in a dominant class or clique; government by the few.”

This definition certainly fits with the IPCC, as illustrated by the closed meeting in which Gerald Meehl, Jonathan Overpeck, Susan Solomon, Thomas Stocker, and Ron Stouffer are organizing in Hawaii in March 2009. This meeting is reported at

Joint IPCC-WCRP-IGBP Workshop: New Science Directions and Activities Relevant to the IPCC AR5 [Tuesday, March 03, 2009 – Friday, March 06, 2009 at the University of Hawaii International Pacific Research Center Honolulu , Hawaii].

While the meeting is to be mostly self-funded [which means [individual] federal contracts and grants and other such sources will be used to pay for the trip], it raises the issue as to why such a remote location is chosen. Presumably the participants should be concerned about the emission of CO2 into the atmosphere from the jet aircraft that will transport them to Hawaii.

The Workshop is also open to only the IPCC Working Group 1 Lead Authors [LAs] and Contributing Lead Authors [CLAs] from all four assessments.  While the goals of the Workshop are appropriate scientific topics, the closed character of the Workshop and its location perpetuates the exclusiveness of the IPCC process.

This small community of climate scientists is controlling the agenda with respect to the assessment of climate change. This is an oligarchy.

I concluded that post with

Without new scientists leading the IPCC process as LAs and CLAs, the next IPCC report is doomed to continue to be completed by an oligarchy that is using its privileged position to advocate for a particular perspective on the role of humans within the climate system [the third hypothesis above]. The next IPCC report will not be a balanced assessment, but continue to be policy advocacy in the guise of a scientific framework.

My Comments For The InterAcademy Council Review of the IPCC

where I recommended that

Future assessment Committees need to appoint members with a diversity of views and who do not have a significant conflict of interest with respect to their own work. Such Committees should be chaired by individuals committed to the presentation of a diversity of perspectives and unwilling to engage in tactics to enforce a narrow perspective. Any such committee should be charged with summarizing all relevant literature, even if inconvenient, or which presents a view not held by certain members of the Committee.

A very recent excellent publication on the major failings of the current IPCC type assessment process is given in

What is Wrong with the IPCC: Proposals for Radical Reform by Ross McKittrick.

Unfortunately,  despite these indictments regarding the failure of the current climate assessment process, the same approach continues. The reason is clear.  There is a symbiotic relationship among funding agencies, principal investigators, national and international assessment committees, and the leadership of professional organizations to continue the huge amounts of research funding.  The results of this funding is often headlined to the media in press releases, so as to influence political decisions regarding a wide range of social and environmental issues, including energy. 

There is no internal stimulus among these groups to change the current approach. Such change will need to be imposed from outside of these venues, particularly from those in government who oversee this wasteful funding.

The Stable Boundary Layer And Climategate #2

In the Climategate #2 e-mails, Peter Thorne is shown joking about the concept that the surface temperatures can be decoupled from the temperatures higher in the atmosphere and this could have an important effect on the interpretation of multi-decadal surface  and lower tropospheric temperature trends. This is an issue that we have explored quantitatively in our papers; e.g. see

History does not relate to whether these were day time or night time ascents but clearly the boundary layer is now seriously decoupled from the near-surface. You read it here first!

Operational Radiosonde Network – data quality issues

Towards the end of July, radiosonde operators and data users began to notice anomalous ascent data with a small number of the radiosondes used within the Met Office network. These sondes reported a jump in atmospheric temperature between surface and the 2-second data point, approximately 10m above the ground. Operators continued to monitor all flights, informing the forecasters when the data appeared suspicious. In the extreme cases, the temperature dropped by as much as 30 degrees! Analysis began immediately to try and identify any trends in the
anomalous ascents. Archived high resolution data for the operational network was re-processed for all ascents between January and July 2009, to interrogate the surface to 2-second differentials. It was concluded that this problem was only evident in specific batches of radiosondes.

The manufacturers were alerted and presented with the evidence and agreed to replace all remaining stock under warranty. This amounts to approximately 500 radiosondes ‘sitting on the shelf’ that are currently in the process of being replaced. The Met Office radiosonde operators were all made aware of the problem, and the operational network stopped using the suspect batches with immediate effect. Operators’ experiences of using more recent stock suggests that this problem has been resolved.

Peter Thorne, Climate Research scientist
Met Office Hadley Centre, FitzRoy Road, Exeter, EX1 3PB.

Peter Thorne now works with Tom Karl and Tom Peterson at NCDC.  His e-mail was, of course,  a joke, but it also highlights a lack of knowledge (and an arrogance) about the issues with respect to accurately modeling and explaining observed surface air temperature trends over land. However, as of 2011, our findings remain unrefuted in the peer-reviewed literature.

Recently there was a Worksop at ECMWF in Exeter, UK that updates the science community on the significant limitations of the representation of the nighttime (including winter arctic and antarctic) boundary layer of  climate models. This includes the ability to skillfully model the vertical temperature profile near the surface. The workshop was

Workshop on Diurnal cycles and the stable atmospheric boundary layer

with the description [highlight]

 22 November 2011 A workshop was held at ECMWF on “Diurnal cycles and the stable atmospheric boundary layer” from 7 to 10 November 2011. The workshop attracted about 60 participants, from Europe and other parts of the world, including Japan, North and South America and Australia.

The workshop was organised together with the GEWEX Atmospheric Boundary Layer Studies (GABLS) working group and co-sponsored by ECMWF, the World Climate Research Programme (WCRP), the Global Energy and Water Cycle Experiment (GEWEX), and GABLS.

One of ECMWF’s strategic goals is to improve the quality of near-surface weather products like temperature and wind and atmospheric composition. It is well known that the diurnal cycles of temperature and wind are strongly influenced by small-scale atmospheric processes in the stable boundary layer, in particular by turbulent diffusion, gravity waves and radiation, but also by the thermal coupling with the underlying soil through vegetation and snow. Most large-scale atmospheric models utilize rather diffusive boundary layer schemes resulting in stable boundary layers that are too thick and which show too little wind turning. Climate projections also show strong temperature signals at high latitudes which are affected by the processes mentioned above.

More details can be seen at ECMWF/GABLS Workshop including the presentations here.

As an example of the specific conclusions from the talks at this workshop, Dick McNider summarized observed data that documents that warming has been much larger in minimum temperatures than maximum temperatures, and that the global climate models do not accurately simulate this asymmetry in his talk

Response and Sensitivity of the Stable Boundary Layer to Added Downward Long-wave Radiation

As he showed

This asymmetry in warming is one of the most significant signals in the observed climate record

His conclusions, based on his modeling study are that most of this warming is from  a vertical redistribution of heat, not an overall warming of the lower atmosphere. His conclusion slide reads

  • The positive feedback due to a redistribution of heat when the SBL is destabilized by added downward radiation may be part of the reason for the differential rise in observed minimum temperatures.
  • The models/processes presented here that have increased temperature of 0.5-1.0K would explain a significant part of the differential minimum temperature warming.
  • Global models don’t have the mechanisms or resolution to capture this feed back.
  • Downward radiation by aerosols which is also not handled well in GCMs may play a major role in the warming of minimum temperatures.

In terms of Peter Thorne’s statement “Maybe Pielke Sr. was right all along …”,  apparently so. :-)

Further Documentation Of Inappropriate Behavoir By A Subset Of Members Of The CCSP 1.1 Committee And The NRC Review Committee

The released e-mails provide a glimpse into  inappropriate behavior by members of the CCSP 1.1 Committee and Phil Jones.  The CCSP 1.1 report Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences was published in 2006.  My view of that report was, and remains, that while there is useful and scientifically valuable information in it, it avoided discussing a number of substantive questions , including  the robustness of the multi-decadal land surface temperature data of NCDC (Tom Karl), CRU (Phil Jones) and GISS (Jim Hansen).

From my understanding on the committee, we were supposed to keep our discussions internal to the committee. Indeed Phil Jones writes in one of the e-mails ” I’m not supposed to talk to anyone of the report authors !” [the exclamation point was in the e-mail].

In terms of the individuals mentioned below:

1. Phil Jones, Judy Curry and Jim Hurrell  served as committee members of the NRC committee reviewing a draft of the CCSP 1.1 report

2. Tom Peterson, Tom Wigley, Tom Karl, Ben Santer and I were members of the CCSP 1.1 committee

My involvement in the CCSP 1.1 terminated with my resignation in August 2005 as documented on my weblog; e.g. see where I summarized the reasons:

1. There was an inappropriate narrowing of the focus of the CCSP charge to the committee in the report;

2. The circulation of an alternative version of Chapter 6, in which I was Convening Lead Author, in order to enforce this narrow view;

REDACTED Heard back from several sources about the Chicago meeting. Similar sentiments from Jim Hurrell. Email from Tom Peterson below and Jim’s bit pasted in below. It seems that not all was solved – re his last sentence about Pielke !

Sitting in the CCSP meeting, but I wanted to let you know of what I believe is really remarkable progress. And I give much credit to Roy Spencer. He has admitted UAH Tlt has a negative bias, accepting the RSS argument the diurnal cycle correction is of the wrong sign

Hi, Phil,
I just thought I’d send my CCSP trip report on to you too as it discusses the latest developments in MSU VTT matters that I’m sure you will be addressing in IPCC.

Thanks for that. I was just about to get around to rewording that and sending it back. I had to read the first draft of the comments on the Executive Summary from one of the other panel members. Although there is a lot to do, I think you’ll like some of them. Many of the other chapter authors may not, though ! Maybe we’ll end up with some more dissenters ! A lot relate to Fu et al as you might have guessed. We have a conf call next Friday at 4pm my time, when hopefully we’ll get something towards closure on this. I’ve only had emails from two people on the panel and the secretary since I left Chicago. Unfortunately Mike Wallace doesn’t seem to have had time to look through Ch 5 (well very briefly). He was only on the conf call in Chicago for 30 minutes. He didn’t say much.

REDACTEDIn Asheville this week but now back. Had a brief work with Tom K. on the VTT work. So he got a summary like you. I’m not supposed to be talking to anyone of your group except through Tom K. I’ve just got comments on your exec summ from Dennis Hartmann. I’ll go through these this weekend. I think I’ve effectively signed off on Chapters 3 and 5. REDACTEDYou’ll likely have to rewrite the summary to pick up the bullet points from the other 6 chapters. Hopefully you’ll get comments before May 1. We have to finish by April 1 (there is a conf call on the 18th), which will hopefully be it for me. REDACTEDAt the moment the NRC person is having difficulty with my following comment –

I do need to work on the English a little


, but it should be understandable. Tom K is also very fed up with Pielke !
PS Have you been getting postcards from Thomson publishing (?)


about essential science indicators. I have 3, for 3 papers saying they’ve been heavily cited. The 3 are fromREDACTEDand have been cited 57, 68 and 41 times !


3 articles in the top 1% of the field. Articles are the one with Anders Moberg in 2003, one in Science on the last millennium
in 2001 and the one on error estimates from 1997.

REDACTEDOff tomorrow and not back in CRU till March 10. I’m not supposed to talk to anyone of the report authors ! There was a lot of odd things said after the presentations in Chicago last week. We’re charged with writing a report, which will be published but you get to rewrite the report and no-one sees the one we looked at ! What is the point of publishing it ! REDACTED Roger Pielke didn’t come out of it too well. Some thought he had some good ideas but didn’t express them very well.Most thought he just didn’t express them very well. All thought Ben’s was the best chapter. Almost all think RSS is right. Also why is Fu et al. dismissed as controversial?


Likely most work will be needed on Ch 6 and 1, then 2-4 and least for 5. The Exec Summary was deemed OK, but it isn’t a summary of the report,


so you’ll have to do some major reworking. REDACTED Remember I didn’t tell you all this. Lots of details to come – not sure when. Seems a long-winded process.



Thus, while there are science issues discussed in these e-mails, it was an inappropriate interaction between members of the CCSP 1.1 committee and the NRC review panel. These exchanges occurred only with a subset of the CCSP 1.1. committee members.
