Non-condensable Cynicism in Santa Fe
Guest Post by Mark Boslough
The Fourth Santa Fe Conference on Global & Regional Climate Change will be held on Feb 5-10, 2017. It is the fourth in a series organized and chaired by Petr Chylek of Los Alamos National Laboratory (LANL) and takes place intervals of 5 years or thereabouts. It is sponsored this year by LANL’s Center for Earth and Space Science and co-sponsored by the American Meteorological Society. I attended the Third in the series, which was held the week of Oct 31, 2011. I reported on it here in my essay “Climate cynicism at the Santa Fe conference”.
In that report, I described my experiences and interactions with other attendees, whose opinions and scientific competence spanned the entire spectrum of possibility. Christopher Monckton represented one extreme end-member, with no scientific credibility, total denial of facts, zero acknowledgment of uncertainty in his position, and complete belief in a global conspiracy to promote a global warming fraud. At the opposite end were respected professional climate scientists at the top of their fields, such as Richard Peltier and Gerald North. Others, such as Fred Singer and Bill Gray, occupied different parts of the multi-dimensional phase space, having credentials but also having embraced denial—each for their own reasons that probably didn’t intersect.
For me, the Third Conference represented an opportunity to talk to people who held contrary opinions and who promoted factually incorrect information for reasons I did not understand. My main motivation for attending was to engage in dialogue with the contrarians and deniers, to try to understand them, and to try to get them to understand me. I came away on good terms with some (Bill Gray and I bonded over our common connection to Colorado State University, where I was an undergraduate physics student in the 1970s) but not so much with others.
I was ambitious and submitted four abstracts. I and my colleagues were pursuing uncertainty quantification for climate change in collaboration with other DOE labs. I had been collaborating on several approaches to it, including betting markets, expert elicitation, and statistical surrogate models, so I submitted an abstract for each of those methods. I had also been working with Lloyd Keigwin, a senior scientist and oceanographer at Woods Hole Oceanographic Institution and another top-of-his-field researcher. We submitted an abstract together about his paleotemperature reconstruction of Sargasso Sea surface temperature, which is probably the most widely reproduced paleoclimate time series other than the Mann et al. “Hockey Stick” graph. I had updated it with modern SST measurements, and in our abstract we pointed out that it had been misused by contrarians who had removed some of the data, replotted it, and mislabeled it to falsely claim that it was a global temperature record showing a cooling trend. The graph continues to make appearances. On March 23, 2000, ExxonMobil took out an advertisement in the New York Times claiming that global warming was “Unsettled Science”. The ad was illustrated with a doctored version of Lloyd’s graph (the inconvenient modern temperature data showing a warming trend had been removed). This drawing was very similar to one that had been generated by climate denier Art Robinson and his son for a Wall Street Journal editorial a couple months earlier. It wasn’t long before other distorted versions started showing up elsewhere, such as the Albuquerque Journal opinion page. The 2000 ExxonMobil version was just entered into the Congressional Record last week by Senator Tim Kaine during the Tillerson confirmation hearings.
In 2011, my abstracts on betting, expert elicitation, and statistical models were all accepted, and I presented them. But the abstract that Lloyd and I submitted was unilaterally rejected by Chylek who said, “This Conference is not a suitable forum for [the] type of presentations described in [the] submitted abstract. We would accept a paper that spoke to the science, the measurements, the interpretation, but not simply an attempted refutation of someone else’s assertions (especially when made in unpublished reports and blog site).” The unpublished report he spoke of was the NIPCC/Heartland Institute report, which Fred Singer was there to discuss. After the conference, I spoke to one of the co-chairs about the reasons for the rejection. He said that he hadn’t seen it and did not agree with the reasons for the rejection. He encouraged Lloyd and me to re-submit it again for the 4th conference. So we did. Lloyd sent the following slightly-revised version on January 4
Misrepresentations of Sargasso Sea Temperatures by Global Warming Doubters
Keigwin (Science 274:1504–1508, 1996) reconstructed the SST record in the northern Sargasso Sea to document natural climate variability in recent millennia. The annual average SST proxy used δ18O in planktonic foraminifera in a radiocarbon-dated 1990 Bermuda Rise box core. Keigwin’s Fig. 4B (K4B) shows a 50-year-averaged time series along with four decades of SST measurements from Station S near Bermuda, demonstrating that at the time of publication, the Sargasso Sea was at its warmest in more than 400 years, and well above the most recent box-core temperature. Taken together, Station S and paleotemperatures suggest there was an acceleration of warming in the 20th century, though this was not an explicit conclusion of the paper. Keigwin concluded that anthropogenic warming may be superposed on a natural warming trend.
In a paper circulated with the anti-Kyoto “Oregon Petition,” Robinson et al. (“Environmental Effects of Increased Atmospheric Carbon Dioxide,” 1998) reproduced K4B but (1) omitted Station S data, (2) incorrectly stated that the time series ended in 1975, (3) conflated Sargasso Sea data with global temperature, and (4) falsely claimed that Keigwin showed global temperatures “are still a little below the average for the past 3,000 years.” Slight variations of Robinson et al. (1998) have been repeatedly published with different author rotations. Various mislabeled, improperly-drawn, and distorted versions of K4B have appeared in the Wall Street Journal, in weblogs, and even as an editorial cartoon—all supporting baseless claims that current temperatures are lower than the long term mean, and traceable to Robinson’s misrepresentation with Station S data removed. In 2007, Robinson added a fictitious 2006 temperature that is significantly lower than the measured data. This doctored version of K4B with fabricated data was reprinted in a 2008 Heartland Institute advocacy report, “Nature, Not Human Activity, Rules the Climate.”
On Jan. 9, Lloyd and I got a terse rejection from Chylek: “Not accepted. The committee finding was that the abstract did not indicate that the presentation would provide additional science that would be appropriate for the conference.”
I had also submitted an abstract with Stephen Lewandowsky and James Risbey called “Bets reveal people’s opinions on climate change and illustrate the statistics of climate change,” and a companion poster entitled “Forty years of expert opinion on global warming: 1977-2017” in which we proposed to survey the conference attendees:
Forecasts of anthropogenic global warming in the 1970s (e.g. Broecker, 1975, Charney et al., 1979) were taken seriously by policy makers. At that time, climate change was already broadly recognized within the US defense and intelligence establishments as a threat to national and global security, particularly due to climate’s effect on food production. There was uncertainty about the degree of global warming, and media-hyped speculation about global cooling confused the public. Because science-informed policy decisions needed to be made in the face of this uncertainty, the US Department of Defense funded a study in 1977 by National Defense University (NDU) called “Climate Change to the Year 2000” in which a panel of experts was surveyed. Contrary to the recent mythology of a global cooling scare in the 1970s, the NDU report (published in 1978) concluded that, “Collectively, the respondents tended to anticipate a slight global warming rather than a cooling”.
Despite the rapid global warming since 1977, this subject remains politically contentious. We propose to use our poster presentation to survey the attendees of the Fourth Santa Fe Conference on Global and Regional Climate Change and to determine how expert opinion has changed in the last 40 years.
I had attempted a similar project at the 3rd conference with my poster “Comparison of Climate Forecasts: Expert Opinions vs. Prediction Markets” in which my abstract proposed the following: “As an experiment, we will ask participants to go on the record with estimates of probability that the global temperature anomaly for calendar year 2012 will be equal to or greater than x, where x ranges in increments of 0.05 °C from 0.30 to 1.10 °C (relative to the 1951-1980 base period, and published by NASA GISS).” I included a table for participants to fill in, and even printed extra sheets to tack up on the board with my poster so I could compile them and report them later.
This idea was a spinoff of work I had presented at an unclassified session of the 2006 International Conference on Intelligence Analysis on my research in support of the US intelligence community for which a broad spectrum of opinion must be used to generate an actionable consensus with incomplete or conflicting information. That was certainly the case in Santa Fe, where there were individuals (e.g. Don Easterbrook) who were going on record with predictions of global cooling. By the last day of the conference, several individuals had filled in the table with their probabilistic predictions and I decided to leave my poster up until the end of the day, which was how long they could be displayed according to the conference program. I wanted to plug it during my oral presentation on prediction markets so that I could get more participation. Unfortunately when I returned to the display room, my poster had been removed. Hotel employees did not know where it was, and the diverse probability estimates were lost.
This year I would be more careful, as announced in my abstract. But the committee would have no part of it. On Jan 10 I got my rejection letter:
I regret to inform you that we have decided to decline this submission.
Based on our consideration of the abstract and plan, it is our view that designing a survey that accurately elicits expert opinion requires special expertise as the answers can depend on how the questions are asked. No indication of such expertise was presented in the abstract itself or found based on examination of your publication record.
A further concern dealt with the proposed comparison with opinion elicited at a different time from a different community by a different method that might allow one to “determine how expert opinion has changed in the last 40 years.”
Concern was raised also over how one might legitimately transform the results of such a poll into “into probabilistic global warming projections.”
Although we cannot accept this poster, we certainly look forward to your active participation in the Conference.
Of the hundreds of abstracts I’ve submitted, this is the only conference that’s ever rejected one. As a frequent session convener and program committee chair myself, I am accustomed to providing poster space for abstracts that I might question, misunderstand, or disagree with. It has never occurred to me to look at the publication list of a poster presenter, But if I were to do that, I would be more thorough and look other information, including their coauthors’ publication lists and CVs as well. In this case, the committee might have discovered more than a few papers by one of them on the subject, such as Risbey and Kandlikar (2002) “Expert Assessment of Uncertainties in Detection and Attribution of Climate Change” in the Bulletin of the American Meteorological Society, or that Prof. Risbey was a faculty member in Granger Morgan’s Engineering and Public Policy department at CMU for five years, a place awash in expert elicitation of climate (I sent my abstract to Prof. Morgan–who I know from my AGU uncertainty quantification days–for his opinion before submitting it to the conference).
At the very least, I would look at the previous work cited in the abstract. The committee would not have been puzzled by how to transform survey data into probabilistic projections if they had done so. They would have learned that the 1978 NDU study we cited had already established the methodology we were proposing to use. The NDU “Task I” was “To define and estimate the likelihood of changes in climate during the next 25 years…” using ten survey questions described in Chapter One (Methodology). The first survey question was on average global temperature. So the legitimacy of the method we were planning to use was established 40 years ago.
I concluded after the 3rd Santa Fe conference that cynicism was the only attribute that was shared by the minority of attendees who were deniers, contrarians, publicity-seekers, enablers, or provocateurs. I now think that cynicism has something in common with greenhouse gases. Cynicism begets cynicism, to the detriment of society. There are natural-born cynics, and if they turn the rest of us into cynics then we are their amplifiers, just like water vapor is an amplifier of carbon dioxide’s greenhouse effect. We become part of a cynical feedback loop that generates distrust in science and the scientific method. I refuse to let that happen. I might have gotten a little steamed by an unfair or inappropriate rejection, but I’ve cooled off and my induced cynicism has condensed now. I am not going to assume that everyone is a cynic just because of a couple of misguided and misinformed decisions.
As President Obama said in his farewell address, “If you’re tired of arguing with strangers on the Internet, try talking with one of them in real life.” So if you are attending the Santa Fe conference, I would like to meet with you. If you are flying into Albuquerque, where I live, drop me a line. Or meet me for a drink or dinner in Santa Fe. I can show you why Lloyd’s research really does provide additional science that is relevant to the conference. I can try to convince you that prediction markets are indeed superior to expert elicitation in their ability to forecast climate change. Maybe I can even talk you into going on record with your own probabilistic global warming forecast!

AGU 2016
It’s that time of year again. Fall AGU is the biggest gathering of geophysical scientists in the world (~24,000 attendees) and while it includes planetary science, seismology and magnetophysics, it is swamped by earth scientists, whose work covers the atmosphere, oceans, cryosphere, climate, natural hazards and paleoclimate.
As in previous years, many sessions and most of the keynotes will be available On-Demand (which is free but you do need to register) and there is a E-poster facility that lets non-attendees view some of the posters.
Some interesting sessions related to discussions at RealClimate will be the “Betting on Climate Change” (Mon, posters), “El Niño: Global Anomalies and Societal Impacts at Regional Scale” (Wed, Union Channel On-demand), and “The Up‐Goer Five Challenge: A Fun and Radical Way to Distill Your Science” (Fri). Of course, there are always the usual paleo-climate (e.g. Climate of the Common Era), model evaluation, and observational sessions to follow.
Keynotes from Isaac Held, Christine Hulbe, Nathalie Cabrol, Daniel Jacob and Bette Otto-Bleisner all sound promising, covering tropical cyclones, the last glacial maximum, the West Antarctic Ice Sheet, air quality and astrobiology (though probably not all at once).
If there are any other specific sessions or talks, you’d like to advertise or comment on, put them in the comments. Discussion on Twitter is using the #AGU16 hashtag. If anyone wants to write up some sessions or highlights, send them along and we’ll post them.
Defending Climate Science
Guest commentary from Lauren Kurtz
The Climate Science Legal Defense Fund (CSLDF) was founded in September 2011 to defend climate scientists from harassing and invasive attacks via the legal system. Five years in, we’re expanding our efforts to reflect the new challenges scientists face, including increasing education and outreach work. Now more than ever, it’s important that scientists prepare themselves for how best to deal with political harassment or legal intimidation. Below are 10 things that every scientist should consider.
In addition, for those in San Francisco next week for the American Geophysical Union (AGU) Fall Meeting, please consider attending one of our events. We’re hosting a symposium on how open records laws have been used to attack scientists on the morning of Wednesday, December 14, which includes a talk from Michael Mann. Our booth in the Exhibit Hall (booth 1523) will also have free legal education materials, including our new Pocket Guide to Handling Political Harassment & Legal Intimidation. And as in years past, email lawyer@climatesciencedefensefund.org to schedule a free in-person consultation with a lawyer at AGU.
1 – Take a deep breath & remember other scientists have gone through this before
First remember that other scientists have been through this before and come out the other side. And while being the target of an attack is frustrating and intimidating, you are not alone. Groups like CSLDF exist to help defend, connect scientists under attack to other researchers who have been through this before, and ensure that scientists can keep their focus on their work.
2 – Call a lawyer if in doubt
If you’re worried that you’re becoming the target of harassment or intimidation, including receiving a request that seems politically motivated, seek counsel before you respond. Your institution likely retains legal counsel that you can contact, but it is important to remember that your institution’s counsel represents the institution’s legal interests, which may differ from your own.
You can always contact CSLDF, where our mission is to provide free legal counsel to climate scientists facing attacks as a result of their work. Call (646) 801-0853 or email lawyer@climatesciencedefensefund.org
3 – Understand whether state and/and federal open records laws may apply to you
One common legal attack on scientists has been through open records laws—the federal Freedom of Information Act (FOIA) or state equivalents. Intended (and mostly used) to promote transparency by allowing citizens to request copies of government records, these laws have also become a tool used to harass scientists. Publicly funded scientists have received open records requests for reams of documents, including emails, peer review correspondence, and preliminary drafts. Scientists employed by the government or by public universities, or who have received government grants—including National Science Foundation (NSF) grants—should recognize that open records laws may apply to them.
Understand whether state and/or federal open records laws are applicable to you. Reach out to your institutional counsel, the staff in your institutional records office, or a legal group like CSLDF who can help you understand the laws that may affect you.
4 – Separate personal and professional emails
Do not use professional email accounts for personal emails and vice versa. Separating personal and professional emails reduces the likelihood that personal correspondence will be affected by an open records request (which only applies to public records) or other legal action related to your work. Similarly, avoid any temptation to use your personal email account for professional correspondence. If it can be shown that your personal email contains professional records, this may result in you needing to turn over your personal email account to legal review. (Editor’s note: This is really important to minimizing time and effort that need to be devoted to dealing with requests or legal actions. Do it now.)
5 – Remember that emails are not always private
Emails may be disclosed due to open records requests or legal actions, or can be hacked. Be sure to conduct professional correspondence in a professional manner. If you are discussing a sensitive issue, consider having an in-person or telephone conversation instead of emailing.
6 – Understand record-keeping requirements
Employees and consultants at public institutions, including government scientists and public university researchers, should retain all public records. The precise definition will vary by state, but generally, these are documents relating to public business.
Be aware that grants may require that you follow specific record-keeping rules: for example, NSF grants stipulate that research data, including databases, must be shared.
Even if no strict document retention requirements apply to your situation, we recommend that you keep files for a few years, as anyone can be made to look bad when things are missing.
7 – Exercise discretion when talking to a journalist
Before agreeing to speak to a reporter or interviewer, research their work. Think carefully about how or whether to speak with a hostile journalist, as you are unlikely to change their opinions, and you may instead provide more fodder for an attack. (Also understand your institution’s rules for speaking to the press and otherwise communicating your research to the public, and when clearance requirements may apply.) If you do choose to speak to a reporter, come to the interview well prepared. Consider the questions you are likely to be asked and outline draft answers. For higher-profile situations, your institution’s public relations office or scientific society may be able to assist you with preparing your message. (Editor’s note: See also the UCS guide to talking to the media for scientists.)
8 – If you receive harassing messages, do not respond and do not delete
Do not respond to messages you feel were sent in bad faith – instead archive or save, in case you ever need evidence to prove that it happened, which is especially important if the situation escalates. Look for signs that the sender is wasting your time or seeking to provoke you, as a correspondent may be seeking to rattle you, use your response to malign you publicly, and/or use your response as a launchpad for further harassment. If you do respond to a seemingly valid inquiry, remember that any response you write may be forwarded or published online, and be cognizant of the time lost by caught up in endless back-and-forth arguments. (Editor’s note: See also the UCS guide to responding to criticism or personal attacks.)
9 – If you receive threatening messages, contact your employer / law enforcement
Report the threats to your institution (your supervisor and the human resources staff are probably the best starting points) as well as law enforcement. Contact a legal group such as CSLDF, especially if law enforcement becomes involved. A lawyer can help you navigate the situation.
10 – For more information on particular legal situations, check out our new Pocket Guide to Handling Political Harassment & Legal Intimidation
Our 16 page guide has more specific advice on how to protect yourself against and/or respond to political or legal attacks. As mentioned above, free copies will be available at our climate science & law symposium on the morning of Wednesday, December 14, and at our booth in the AGU Exhibit Hall (booth 1523). You can also join our email mailing list to be notified as soon as electronic copies are available on our website, as well as stay updated on other CSLDF developments.

Don’t make a choice that your children will regret
Dear US voters,
the world is holding its breath. The stakes are high in the upcoming US elections. At stake is a million times more than which email server one candidate used, or how another treated women. The future of humanity will be profoundly affected by your choice, for many generations to come.
The coming four years is the last term during which a US government still has the chance, jointly with the rest of the world, to do what is needed to stop global warming well below 2°C and closer to 1.5°C, as was unanimously decided by 195 nations in the Paris Agreement last December. The total amount of carbon dioxide the world can still emit in order to have at least a 50% chance to stop warming at 1.5 °C will, at the current rate of emissions, be all used up in under ten years! This time can only be stretched out by making emissions fall rapidly.
Even 2°C of global warming is very likely to spell the end of most coral reefs on Earth. 2°C would mean a largely ice-free Arctic ocean in summer, right up to the North Pole. Even 2°C of warming is likely to destabilize continental ice sheets and commit the world to many meters of sea-level rise, lasting for millennia. Further global warming will likely lead to increasing extreme weather, droughts, harvest failures, and the risk of armed conflict and mass migration.

In case you have any doubts about the science: in the scientific community there is a long-standing consensus that humans are causing dangerous global warming, reflected in the clear statements of many scientific academies and societies from around the world. None of the 195 governments that signed the Paris Agreement saw any reasons for doubting the underlying scientific facts; doubts about the science that you see in some media are largely manufactured by interest groups trying to fool you.
You have a fateful choice to make. The policies of candidates and parties on climate change could hardly be more different. Hillary Clinton would continue to work with the international community to tackle the global warming crisis and help the transition to modern clean and renewable energies. Donald Trump denies that the problem even exists and has promised to go back to coal and to undo the Paris Agreement, which comes into force today, the 4th of November 2016, as culmination of over twenty years of negotiations.
Please consider this carefully. This is not an election about personalities, it is about policies that will determine our future for a long time to come. While the presidential race has gotten the most attention, voters should consider climate not just at the ‘top of the ticket’, but all the way down the ballot. Don’t make a choice that you, your children and your children’s children will regret forever.
David Archer, Rasmus Benestad, Ray Bradley, Michael Mann, Ray Pierrehumbert, Stefan Rahmstorf and Eric Steig
