Mann Fights Back Against Denialist Abuse
Posted on 28 July 2012 by dana1981
At Skeptical Science, we prefer to stick to discussions of the scientific literature and body of evidence. However, for the long time there has been a systematic abuse of climate scientists from climate denialists, and from time to time this reprehensible behavior becomes so widespread that we feel the need to comment on it, for example in the cases of Katharine Hayhoe and Phil Jones.
Most recently, Michael Mann, who himself has a long history being on the receiving end of abusive letters and death threats, as he detailed in his book, has been rather viciously defamed by the Competetive Enterprise Institute (CEI) and National Review. CEI is a right-wing think tank with a long history of denying the health effects of smoking and human-caused climate change, having received major funding from the tobacco and oil industries (i.e. over $2 million from ExxonMobil, and more recently funding from the Koch Brothers and other groups whose wealth is based in fossil fuels like the Scaife Foundations).
Recently, Ryan Simberg published a post on CEI's blog accusing Mann of
"engaging in data manipulation to keep the blade on his famous hockey-stick graph"
The CEI blog post proceded to compare Mann to Jerry Sandusky, a convicted serial child molester. This extraordinarily inappropriate and offensive comparison has been removed from the CEI blog, but it remains in a National Review article written by Mark Steyn, which quotes Simberg's post. We will not reproduce this reprehensible quote here.
Libelous Accusations of Fraud
The accusations of fraud are of course entirely baseless, but stem from the "Mike's Nature trick" email which was made public during the Climategate theft. "Mike's Nature trick" referred to the technique of plotting recent instrumental temperature data along with historical reconstructed data. This places recent global warming trends in the context of temperature changes over longer time scales. This graph is commonly known as the "hockey stick."
There is of course nothing 'fraudulent' about plotting instrumental temperatures on the same graph as reconstructed temperatures. Both the instrumental (red) and reconstructed temperature (blue) are clearly labelled in Mann's 1998 Nature article, the follow-up Mann et al. 1999, and the IPCC Third Assessment Report (TAR) (Figure 1).
Figure 1: Northern Hemisphere mean temperature anomaly in °C (IPCC TAR).
There has been subsequent scientific debate regarding the statistical methods used in Mann et al. 1999. It was after all a groundbreaking study - one of the first northern hemisphere millennial temperature reconstructions, so of course subsequent research has resulted in improved methodologies, even by Mann himself in Mann et al. 2008 (Figure 2).
Figure 2: Composite Northern Hemisphere land and land plus ocean temperature reconstructions and estimated 95% confidence intervals. Shown for comparison are published Northern Hemisphere reconstructions (Mann 2008).
However, there is zero evidence that there was any fraudulent behavior whatsoever Mann et. al 1999, and in fact every subsequent millennial northern hemisphere temperature reconstruction has confirmed the general 'hockey stick' shape. For example, see the summary of subsequent research on the subject in the 2007 IPCC report.
Additionally, every investigation into the Climategate emails found that the scientists whose emails were stolen, including Michael Mann, were not guilty of any wrongdoing. Quite simply, any accusations of fraud are entirely without merit, and qualify as defamation and libel.
Sandusky Comparison Beyond the Pale
It should go without saying that comparing anyone - particularly an honest scientist - to a convicted serial child molester is simply reprehensible and should be universally condemned. We would hope that CEI and National Review would acknowledge their writers' blatant lapses in judgment, retract the articles, and issue a profound apology to Mann for their defamation and libel. As noted above, CEI has taken the small step of removing what they call the "Two inappropriate sentences."
So far National Review has taken no action, and Mann has retained legal counsel who has issued a letter to National Review stating:
"Needless to say, we intend to pursue all appropriate legal remedies on behalf of Dr. Mann...we reiterate our demand that this defamatory article be immediately removed from further publication, and that you issue a retraction of this article and an apology to Dr. Mann."
The letter also used the Skeptical Science Climategate rebuttal to illustrate why the accusations of fraud are entirely baseless and without merit - we are pleased to have been a useful resource in Dr. Mann's endeavors on this matter.
Comments from the Peanut Gallery
Mann's move onto the offensive has generated widespread commentary from the blogosphere. For the most part there has been a great deal of support, for example on AGU blogs, Climate Crocks, Discover Magazine's Bad Astronomy, and many others, including comments on Mann's Facebook Page. However, a number of climate denialists have inexplicably sided with CEI and National Review's defamatory attack, for example Andrew Montford and WattsUpWithThat, among others.
Denialists Frothing Up the Abusers
There is a clear connection between the behavior at climate denialist blogs and the abuse directed towards climate scientists. Denialist blog posts constantly leap from their own flawed scientific analyses to the conclusion that climate scientists must be guilty of fraud, data manipulation, and other immoral behavior. The letters received by climate scientists contain this same sort of language, with baseless accusations of fraud and data manipulation, followed by abusive language and often death threats.
Climate denialist blogs are also the source of the CEI and National Review accusations of fraud, which soon warped into a denigrating comparison betwen an honest climate scientist and a serial child molester. Instead of condemning this reprehensible behavior, climate denialist ringleader WattsUpWithThat in particular appears to encourage it.
This sort of behavior must stop, especially if these climate denialists wish to be taken seriously as real 'skeptics'. It is completely unacceptable that honest climate scientists like Mann, Jones, and Hayhoe - who are just trying to do their jobs and further the collective human understanding of the inner workings of our climate - are being subjected to abusive attacks and death threats as a reward for their efforts.
We call on all climate 'skeptic' blogs to condemn the defamatory language from CEI and National Review, and the abuse directed towards climate scientists in general, and we wish Dr. Mann well in his efforts to hold National Review liable for its defamation of his character.
For those who wish to support Dr. Mann in this matter, donating to the Climate Science Legal Defense Fund is one option.
I'm sorry to be lazy again, but I'm looking for the quickest possible response to the denier claim that Michael Mann "has refused consistently and insistently to supply the basic data used behind these constructions".
I tried phrasing my querry various ways in the search engine, but didn't come up with anything useful.
[JH] Perhaps you need to devote more time to doing your own research. Your stream of apologies for being lazy is beginning to wear thin.
PS The reason my question is relevant to this thread is that deniers are using the recent win of Tim Ball against Mann in Canadian court as evidence that he won't provide his data:
MICHAEL MANN FACES BANKRUPTCY AS HIS COURTROOM CLIMATE CAPERS COLLAPSE
[JH] Please refrain from posting quotes from climate denier websites — especially statements that are patently false.
dvaytw @42, those allegations were made on Feb 21 of this year. On Feb 22, Michael Mann responded by posting a letter from his lawyer on face book:
Tom, as nutty as a lot of denialist blogs are, I'm finding this hard to believe. You mean that website is totally fabricating the claim that Mann's lawsuit has been dismissed?!? (or Ball is, and they are parroting his claim)
That is nuts. Everyone and anyone will be able to check and refute this. Does anyone know more about this? I haven't been able to find a single reputable news source saying anything about it - but of course lots of denialist blogs posted it.
[JH] "Reliable news sources" do not typically pay attention to what is being posted on the websites of known crackpots.
dvaytw. as Tom has pointed out, the entire 'Tim Ball victory' story was a bizarre bit of fiction. I can't believe deniers are still managing to live in that alternate reality months after the fact.
Information about the data for the 'hockey stick' can be found here;

Of course, the fact that the National Academy of Sciences and numerous individuals (including 'sceptics' like McIntyre) have reviewed this data makes the continued claims that it isn't available right up there with Tim Ball's amazing non-existent court victory in the category of 'evidence that these people are mentally ill'.
[RH] Sorry, your link was breaking the page format by just a smidgen.
Dear JH. Please accept my apologies. I waste a lot of my time trying to slap down denier arguments in various forums and comments sections under articles. In this case everything that came up in Google was mirrored from a denier blog, and noting pertinent was found in your search engine . Usually I can get an answer here in lightning fast time (as with this case). Honestly, if I don't do that, I'll probably just have to concede some points because it certainly isn't worth spending a whole heap of time looking such things up.
If such lazy inquiries aren't welcome here, can anyone recommend another place where they can be made effectively?
Finally, I fully understand if you want to delete my inquiries in this thread, and will try to refrain in the future. Also, point taken about quoting and linking to the article.
[JH] I purposely prodded you to make sure that you were not engaging in an elaborate ruse in order to spread denier poppycock on this site. I am now staisfied that you are not doing so. Please do continue to seek expert advice on this website. However, please do not apologize every time you do so.
Yes it occurred to me that you might think that, and given my experience with such people, I totally understand why you would! And thanks again to the responders above... man did I just make one very smug fellow look bad!
JH, if you want independent confirmation that dvaytw is on the level, you might like his ringing endorsement of SkS at Scientific American. Also, rather than asking him (or others seeking informed advise) not to apologize, it may be better to ask them to link back to the discussion on which they are seeking advice (if it is online). That way we can check the context of the claims, directly participate if we think it would be helpful, and coincidentally confirm for ourselve the bona fides of the person asking questions on SkS.
[JH] Thank you for the reference and your suggestion.
dvaytw - As per earlier discussions where exactly the same thing happened (you presented a denial viewpoint asking for refutation, but did not clearly show that it _wasn't_ concern trolling, leading to predictable reactions from the moderators), it would be exceedingly helpful if you would link where these off SkS discussions were occurring.
Context matters. You are again failing to provide any.
[JH] I concur.
KR @49, please read the comment linked in my post @48. It is very clear from it that dvaytw is exactly as he presents himself, a person who accepts the science and comes to SkS for help with issues he has not seen before. Clearly any misunderstandings in the past were exactly that, and it would behove use to pay more attention to our contribution to such misunderstandings rather than direct the blame solely at dvaytw.
Having said that, I agree with your suggestion of links to off site discussions when advise is being sought.
