Responding to Roger Pielke Jr. Misrepresenting My Employment History

Update September 4 2018: Roger finally acknowledged that I’ve never had any paid or unpaid relationship with any organization involving any campaign focused on him or his work. That was easy. I sincerely hope that Roger learns how to engage in debates about climate policy and science communication without making things up about people who disagree with him. 

Update June 10 2018: Roger chimed in on a Twitter thread with two other climate folks. I asked him, once again, to correct his misrepresentations of my professional relationships. He told me to go to his university to make a research integrity complaint even though this obviously isn’t a research integrity issue. When I asked him for evidence to back up his claims, he muted me. 

Roger Pielke Jr. is a political scientist based at the University of Colorado Boulder. He’s made some contributions to the literature on how scientists interact with policymakers. He’s also a contentious public figure who regularly criticizes climate researchers for their communications and advocacy work, particularly when it doesn’t comport with his preferred methods of political communication and advocacy.

This puts Pielke Jr. in a strange position: although he says he supports some climate and clean energy policies, his work is also regularly cited by right wing political actors who want to undermine the credibility of climate science and climate scientists. At the same time he hasn’t been able to convince climate researchers that his theories about the best way to do political advocacy are correct.

I’ve had a mild share of public disagreements with Pielke Jr. over the years. Unfortunately, he’s decided to make those disagreements personal and has acted uncharitably and unprofessionally toward me in response, accusing me of being part of a conspiracy meant to undermine his work as opposed to someone who simply disagrees with his views.

Over the past few years, Roger has:

  • falsely accused me of being paid to attack him by the Center for American Progress (source / screencap)
  • falsely accused me of being linked to what he thinks was a Tom Steyer-backed campaign to attack his work (source / screencap)
  • made up a quote from me regarding a dispute he had with a member of Congress (source / screencap)
  • published my correspondence without my permission (source / screencap)

When I asked Roger to stop doing this, he accused me of leading a cabal of climate scientists against him. Really. (source / screencap)

Politics is contentious. So researchers who participate in it should be willing to disagree without being disagreeable. As I’ve written previously, dealing with misinformation directed at one’s professional relationships can be difficult. But it’s best to collect the misinformation in one spot, debunk it, and hold the people spreading the misinformation accountable.

So this is an attempt to practice what I preach. I truly believe Roger wants what’s best for the scientific community and society. I do, too. If we disagree about how to get there, so be it. But there’s no need for him to misrepresent my employment history.

Below, see some useful context as well as the correspondence Roger and I agreed to publish online before he stopped responding to me. I’ve also included his subsequent tweet in which he attempted to decontextualize our conversation and falsely accuse me of leading a cabal of climate scientists against him.

If Roger would like to correct anything in this post, he’s welcome to contact me at his leisure. I look forward to him eventually addressing the points I’ve raised and correcting his public misstatements about me.

March 2014 to July 2014: Pielke Jr.’s Tenure at 538

In March 2014, Pielke Jr. got a gig writing for Nate Silver’s data, politics and sports site 538. He used his first essay to go back to a favorite topic: extreme weather damage and climate change. This is not a uncontroversial topic and Pielke Jr. got pushback from scientists, climate writers and bloggers at Think Progress, the news and commentary arm of the Center for American Progress, and Forecast the Facts, (later, an advocacy organization that was created to foster accuracy in climate coverage.

Pielke Jr. thought those criticisms were unfair and out of bounds, but he also responded to them with clearly out-of-bounds behavior of his own, writing to scientists and their bosses demanding they retract their public criticisms and noting in at least one case that their disagreements with his work might be “libelous.” That’s not a word people who work for media outlets usually throw around, especially in the United States, and 538 apologized to the scientists Roger emailed. Nate Silver, 538’s founder, told the Huffington Post: “We made clear that Roger’s conversations with them did not reflect FiveThirtyEight’s editorial values.”

Later, Pielke Jr. described 538 as being reluctant to publish more from him. Fast forward to 2016: Pielke Jr. found that he was mentioned in one of the emails hacked from John Podesta. The email is from a CAP employee telling Tom Steyer the founder of NextGen Climate (now NextGen America) and a board member at CAP about their efforts to hold 538 accountable for publishing Pielke Jr.’s article. If Steyer or Podesta bothered responding, it wasn’t in the hacked archives, but Pielke Jr. went on to write an oped in the Wall Street Journal based on this single email, comparing people who disagreed with him to “thought police.”

February 2015 – Publishing correspondence without my permission and making up a quote from me

In 2015, Pielke Jr. got a letter from Rep. Raul Grijalva asking about his financial ties to the fossil fuel industry. Pielke Jr. thought this was inappropriate, echoing other letters right-wing members of Congress have sent climate scientists demanding a variety of information from them. He approached me to ask what the Union of Concerned Scientists, where I worked for nearly a decade, was doing about it.

I sent him a note explaining what we were working on, shared a blog post from a colleague about the incident and asked him to stay in touch. I also told him university counsels usually don’t have researchers’ interest in mind when these incidents happen and that I’d advised other scientists in the same situation to obtain their own counsel. This is pretty standard political advice and indeed, the same advice I’d offered other researchers in similar situations. But Pielke Jr. would later accuse me of telling him to “lawyer up.” I pointed out to him that I never said that and, well, I don’t like when people put quote marks around things I didn’t say. Michael Halpern, my old colleague, pointed this out to Roger on Twitter and Roger responded by publishing my correspondence online without my permission.

My Employment History

  • I worked full time at the Union of Concerned Scientists from 2002 to October 2015.
  • I worked at Cater Communications, a bipartisan clean energy firm from October 2015 to December 2016 as a full time employee and continued to consult for the organization for several months into 2017. During this time, we worked with (formerly Forecast the Facts) as a client. (Their former communications firm had dissolved and I reached out to them.) This was more than a year after Pielke Jr.’s falling out with 538. None of’s work involved Pielke Jr., including the work in which I was involved.
  • During the 2016 election I became increasingly worried Trump would win. I took a leave of absence from my day job to run a field office for NextGen Climate (now NextGen America), Tom Steyer’s group, in Athens, Ohio from September 2016 to November 2016. This work involved registering students to vote and mobilizing them to do so. It had absolutely nothing to do with Roger Pielke Jr.

Pielke Jr. Keeps Making Stuff Up About Me – Our Correspondence

In April 2017, I criticized Pielke Jr.’s over-reaction to scientists disagreeing with him. He accused me of being paid by CAP to attack him and blocked me on Twitter, so I wasn’t able to respond to this accusation at the time.

In February 2018, I commented on a thread with Pielke Jr. and a few scientists and journalists to point out Roger’s habit of accusing people who disagree with him of being politically biased. Roger accused me of trolling and asked me if I was “still on Steyer’s payroll” and then linked to an article about the Podesta email.

Roger failed to respond to me on Twitter, so I emailed him with a request that he stop accusing me of being paid to attack him. I also told him that given his habit of publishing correspondence from me online, that I’d like us to both publicly post our responses. Roger responded and agreed to publish our correspondence publicly.

You can see that correspondence on Twitter and reproduced here below. I think a fair-minded assessment of this exchange is that I am extremely blunt and direct with Roger. At the same time, I think the reader can see how Roger’s responses go from denial, to changing his story, to defensively telling me I can only complain to his university and, finally, abandoning the conversation and publicly accusing me of leading a conspiracy of scientists against him.

That latter point is quite interesting. One of the reasons I kept all this in a continuous thread on Twitter and am reproducing it here is that it’s very easy for misinformers to decontextualize information online. When I advise scientists on how to correct misinformation about their work, I urge them to keep a single thread going on a medium they control, whether a blog or their own Twitter feed.

Here is our correspondence, including links:

My initial note to Roger:

Hello, Roger.

You recently made another inaccurate claim about me in response to my public criticism of your views. As you might have seen, I posted on Twitter to document these claims, including the time you made up a quote from me and two unfounded accusations about getting paid to attack you. I’d appreciate it if you could acknowledge having read my messages.

If you could refrain from spreading lies about me and my work, that’d be super nice, too. This is part of a pattern of unprofessional conduct and immature behavior on your part. Please stop. No one else is to blame for your professional failures but you.

Finally, given your history of publishing correspondence from me online without my permission, you can consider any interactions you have with me a matter of public record. I certainly will.

Aaron Huertas

His response

Hi Aaron,

Sorry, I have not seen your messages. I muted you on Twitter after your latest unprovoked trolling. I’m giving mute a try rather than blocking these days for a select few enthusiastic folks on Twitter.

And yes, I am happy to consider our email exchanges on the record, such as is the case when one works in an official capacity as as a PR spokesperson (or for that matter, as a professor at a public university in Colorado).

All best,

I reiterated the issues I wanted to focus on and clarify:


Uh-huh. So you muted me after you implied I was being paid by Tom Steyer to attack you and posting a link that didn’t back up your claim. Or am I being paid by CAP? You can’t seem to get clear on that.

Anyway, lying about someone’s work, making up a quote from them and publishing their correspondence without their permission are all forms of trolling. What I’m doing is disagreeing with you. I realize it’s a fine distinction in this day and age, but it’s clear in my mind. Anyway, no one has ever paid me to criticize you or your work.

So grow up, dude, especially if you’re still trying to make a career out of telling other academics how to behave.


Roger’s note back was not responsive to all of my claims. At this point, he retreated from accusing me of being paid to attack him with providing services “pro bono.” I’m not sure Roger understands that that still involves having an actual relationship with an organization.


Please publish this response in full:

1. I asked you on several occasions if you were still funded by Tom Steyer, as it is a matter of public record that you had been previously

2. In response, you confirmed that at times in recent years you were in fact paid by organizations funded mainly/solely by Steyer

3. Several of Steyer-funded organizations led a successful national campaign to have me fired from a job

4. Later, thanks to Russians and Wikileaks we know that there was an organized, well-funded, multi-year effort against me by Steyer-funded groups

5. Perhaps your continuing public trolling of me has been provided pro bono and was not part of your job description for these Steyer-funded groups

I am glad for the clarification of these facts and happy to have them out in the open.


I asked Roger to return his focus to his actual statements and whether or not they are correct as opposed to his new narrative:

I referenced two Twitter posts. One where you accused me of being funded by CAP to attack you and another where you accused me of being funded by Steyer to attack you. “Several occasions” would be news to me, but maybe you’ve done some post-and-blocks before and I didn’t know. And, yeah, it’s a matter of “public record” because I’ve blogged and tweeted about it, including more recently in response to you! Lol.

You and 538 parted ways in 2014. I ran a NextGen field office in Athens, Ohio more than two years later, from September 2016 to November 2016. And I told you about that after your latest outburst, too. I was doing GOTV with students. It had nothing to do with you.

I worked with from 2015 to 2016 through my old firm, well after they rebranded from Forecast the Facts and well after their public criticism of your work at 538 had wrapped up.

So your little conspiracy theory doesn’t even have internal logical consistency. Nor have you ever accounted for the fact that you abused your position at 538 by sending threatening emails to scientists who disagree with you. Always easier to blame others for your faults, as per usual for you.

Additionally, saying that my public disagreements with you are provided to anyone “pro bono” is a stupid, misleading way to put it. I have never had a professional relationship with any organization that carried any expectation of work related to you.

We’re both people with strong opinions who post on Twitter. Not that uncommon! The difference is I don’t make shit up about you then block and mute you while accusing you being a troll.

Also way to ignore making up a quote from me. Great cherry pick there, dude.

Seriously, try taking some responsibility for your own words and actions for once.

Hang loose,

Roger stopped responding me, but I followed up, again pointing out specific areas where he refused to acknowledge basic points about my employment history and his actions:

Hey, Roger,
It’s weird that you keep ghosting on me after I point out how you don’t have your facts about me or my work right. But I’m asking you to dig deep here, buddy.
Can you please acknowledge the following points?

-You did not ask me about my employment history or status on “several occasions.”

-I have never had a paid or unpaid relationship with any organization involving any campaign focused on you or your work.

-I have never been paid by CAP.

-My work with NextGen (Steyer’s org.) involved running a field office in Ohio and doing GOTV work with students, i.e. nothing to do with you.

-My work with NextGen and both post post-date your fallout with 538.

-You published correspondence from me online without my permission, regardless of your unique personal beliefs about professors publishing emails from staff at NGOs. (You don’t work for a media organization, last time I checked.)

-You accused me of telling you to “lawyer up” despite the fact that I never told you to “lawyer up” which constitutes making up a quote from me.

Finally, I don’t know that you’ve proven “Several of [sic] Steyer-funded organizations…” did anything related to your brief tenure at 538. I think you’ve proven that someone at CAP emailed Tom Steyer about your work at 538, as you shared in the Daily Camera article, but if he didn’t write back that doesn’t seem like much of a conspiracy you uncovered. But hey, maybe you have more evidence you haven’t publicly shared with anyone or maybe you’re under some kind of NDA. Beats me. Regardless, I’m sure it’s very comforting for you to believe that your professional failures are someone else’s fault and not yours.

And again, it’s weird that you keep leaving out the part where you abused your position at 538 by sending threatening emails to scientists who disagree with you. As Nate Silver told the Huffington Post at the time: “We made clear that Roger’s conversations with them did not reflect FiveThirtyEight’s editorial values.”

So can we get clear on the stuff about me personally? And if you have the guts, your 538 Wikileaks conspiracy theory? Because if anyone did all that to you, you’d be emailing their bosses and berating science advocacy groups into taking your side. Instead, all I’m doing is calling you out publicly and encouraging you to deal with your own behavior and the inaccuracies you’ve spread about me.

If you continue to dodge these points, all you’ll have demonstrated is your continued lack of professionalism.



Roger still didn’t respond to me, so I continued to follow up via email and on Twitter.


Are you going to respond to me or not? If not, why not? Is it because you can’t admit you’re wrong when confronted with your obvious misrepresentations of fact?

In case you haven’t figured it out yet, I’m not letting this go.

Thanks, dude!

After these messages, Roger finally did respond. Not to my points, though. Instead, he decided that he would accuse me of spreading false information about him without identifying what that false information is. Then he hid behind his university position.


I am requesting that you (a) stop spreading falsehoods about me online, and (b) that you also stop harassing me online and via email.

If you sincerely believe that I have engaged in research or academic misconduct, then rather than continued online and personal harassment, I would encourage you to file a formal complaint with the University of Colorado for an official adjudication of your various (false) allegations.

I won’t be responding further.

Thank you,

Roger Pielke, Jr., Professor
Environmental Studies
University of Colorado

I responded to Roger again to let him know this wasn’t the end of it. Unfortunately, we will continue to run into each other in these public debates.

Well, Roger, it’s good we’re doing this publicly, because what’s clear is that I’ve laid out your falsehoods in detail and you refuse to answer for them.

You also can’t seem to document any falsehoods on my part in item (a) there, but whatever.

You lying about me in public doesn’t constitute “research or academic misconduct.” If you’re lying about me in the peer-reviewed literature, let me know, I guess? As I’ve said from the outset, the problem is that you’re engaging in unprofessional, childish behavior in response to simple disagreemeents. The fact that you’d rather hide behind your university’s complaint process instead of dealing with the facts in front of you speaks directly to your lack of intellectual honesty and your lack of professionalism.

Further, as I wrote to you yesterday, I’m not in the business of running off to people’s bosses and places of employment to resolve disagreements for me. That’s your go-to move. And according to public reporting, it appears to be one the major reasons you were fired from 538.

I understand that you won’t be responding. Big whoop. The fact is that we’re both involved in the climate policy debate and will be for the foreseeable future. All I’m saying is that as a professor, as a public communicator and as someone who I truly believe does care about science and science policy, I expect you to do better when you participate in public debates.

Later alligator!

At this point, Roger surprised me.
He tweeted to his followers that I was leading a cabal of climate scientists against him.  Importantly, he did so outside the Twitter thread and email chain we’d maintained in an attempt to decontextualize and reframe our interactions.

Pielke Jr.’s tweet accusing me of participating in a conspiracy theory against him. The three other accounts tagged are all senior scientists who would laugh at the idea of anyone leading them in such a campaign.

This message was re-tweeted dozens of times, including by climate deniers, a birther conspiracy theorist and a few right wing think tank scholars. I wrote Roger again:

Hey, buddy. Hope you had a nice day getting retweeted by climate deniers and cranks. Also glad to know I’m the leader of a group of senior scientists in your latest conspiracy theory. Truly, it feels like a promotion! Again, I’m not interested in complaining to your bosses about your work. That’s stupid. We’re both adults here. What I am going to do is to challenge you—personally and professionally—to do better and to take responsibility for your words and actions.

Keep on keeping on!

If you’ve read this far…
I hope that was useful or just mildly chuckle-worthy. Needless to say, I don’t think Roger is a trustworthy figure in our field. But facts are facts. If he has anything to correct in this post, he’s welcome to contact me and lay them out for me. The idea that I know more about my employment history and professional affiliations than he does honestly shouldn’t be that difficult to grasp. I wish Roger no ill will. I hope he recognizes that spending his career criticizing other people’s communication and advocacy choices means he needs to be able to demonstrate the ability to grapple with criticisms of his communication and advocacy choices, too.
