after your post I have no clue any more what an “honest broker” is supposed to mean, nor what “widening policy options” is supposed to mean.

If I ring the fire brigade and tell them about a fire: do I widen or narrow their options?

I also have a problem with your phrasing: “working to reduce the scope of choice” – it implies I have such an intention, but really I’m just ringing those guys to tell them what I see. I don’t even know whether that widens or narrows their choices.

Maybe I narrow their options: it becomes less viable for them to sit around drinking tea and doing nothing. Or perhaps I widen them: after all they now have more information than before, based on which they can make their decision whether to drink tea or get in the car (or how many cars and firemen to send). I would say: I simply help them to make a better, more informed choice. They can still stay home drinking tea but they have a better idea about the consequences.

To get back to climate: if some new results from paleoclimate suggest that climate sensitivity is very likely in the range 3-4 ºC, rather than 2-4 ºC as previously thought, does this information narrow or widen policy options? And if the result suggested that the range is 2-3 ºC? And that’s just the scientific paper itself. Now we go out at RealClimate and explain that result in popular language: does this narrow or widen policy options? My hope would simply be that the public makes a more informed choice.

I look forward to your explanation.

At least officially, RealClimate was not intended to be a player in climate politics. But, as a consequence, it probably has had some effects on it. The effect may be “scientizing” it, as claimed by Pielke in the previous posting “The Taxonomy of Climate Politics”, though I do not know enough to decide whether this evaluation is precise or not.

(The situation may be compared with this.
No industries, perhaps except some agribusinesses who apply CO2 fertilization, intend to be CO2 emitters. But they may reasonably evaluated as such.)

I think that its aim “The discussion here is restricted to scientific topics and will not get involved in any political or economic implication of the science” is impossible in its strict sense.
I agree with Pielke that there is no clear boundary between climate science and climate policy. On the other hand, I think it possible to pursue the aim in somewhat relaxed sense. Though we must admit that some political or economic issues mix in, I think, we can still have a forum primarily dedicated to climate science.

(Let me take a case within science for comparison. There is no clear boundary between climate and weather. It is inevitable that discussion on science of climate is contaminated with some elements of science of weather. But it does not mean that we always need to include the whole subject of weather in our discussion of science of climate.)

I think that it is better for RealClimate to enforce somewhat stronger moderation than it does now, to keep discussions primarily along its aim. If the moderators consider a comment off-topic, they should remark as such and stop discussions on that line.

I think, however, that it may be better to have, beside the zone of primary topics discussing (the contents of) scientific studies, a zone of secondary topics. Policy implications of a certain scientific knowledge should come here. Also, discussions about stance of the authors (including sources of funding) whose writings are being reviewed in the primary zone should come here. I think it better to make the difference of zones visibly clear. The boundary between the zones is not well-defined, of course, but I do not think that the distinction is absolutely arbitrary.

If this experiment results in dominance of the secondary zone, then the site should better change its aim (to become a climate policy blog or a climate STS blog, perhaps). But I do not think this to be the only consequence. Though uncertain, I expect that there are public needs for a web site primarily discussing the (contents of) science of climate.

Thanks for these thoughtful comments, which I think go some way toward reconciling our different perspectives. Let me take your comments one-by-one. My comments about RealClimate are motivated by RealClimate’s claim to be focusing on science, and not on policy or politics. When challenged on this point RealClimate has offered a passionate defense of a strict separation. I am interested in such claims of separation from both an academic and pragmatic perspective because the field that I am from has conducted considerable research to suggest that such separation just isn’t possible in practice. It is clear that the term “honest broker” raises some hackles (and now that I see this reaction from you, I apologize for the miscommunication). Let me be clear — The term “honest broker” is academic jargon and is not intended to be pejorative in any fashion. I use it in the sense recommended by Dan Sarewitz in the concluding section of his excellent 1996 book, Frontiers of Illusion (Temple University Press). The “honest broker” on policy seeks to expand the scope of choice, as contrasted to the “issue advocate” who works to reduce the scope of choice (as described in my 2003 Nature essay, Policy, Politics and Perspective). Both roles are important in a democracy, and both roles can be fulfilled by persons of the utmost integrity. But let me be clear about one point, one cannot serve as an “honest broker” (expanding choice) and “issue advocate” (reducing choice) at the same time. And once a scientist engages in public dialogue on a topic like climate change (or the house fire in your analogy) one necessarily takes on one of these roles (i.e., there is simply no hiding behind science). As I said in my response to Eric, no where have I suggested that RealClimate is being dishonest or anything other than sincere. (Again, let me be clear, to say that RealClimate is not acting as an honest broker is not at all the same as saying that RealClimate is dishonest, it means that RealClimate’s actions constrain the scope of choice on climate change. In the coming days I’ll post a definition of “honest broker” on the main Prometheus site – thanks for showing me that this is very much needed.) If RealClimate has some preexisting “agenda” I’d have no idea what it is, but I’ve certainly made no such claims. That is a red herring. Given the collected credentials of the RealClimate crew I’d be surprised if the information presented there wasn’t of the utmost quality — there have been no claims from me about distorting information. Your fire analogy is a good one, and nicely illustrates some of the very points I have been making. Once scientists go from studying the dynamics of fire behavior to alerting the fire brigade, it opens up important questions of the connections of science and action, specifically, honest broker or issue advocate (there is no alternative!)? My point in this dialogue with RealClimate is simply that if you are calling for the fire brigade, then good for you (say that), just don’t pretend to equate this with studying the dynamics of fire. Thanks again!

I agree that to get involved in a public discussion is by definition a “political act”, and there is nothing wrong with that – to the contrary, without citizens getting involved, no democracy can work.

But what I do strongly object to are your stated or insinuated further steps: from the “political act” you go on to suggesting we have a “political agenda”, and next you go on to suggest that we therefore are not “honest brokers”. This can very easily be read as you suggesting we are dishonest, and I would like you to very clearly state that this is not what you are suggesting.

Let’s clarify the issue with a simple example. I walk along a street and discover a house fire that has not been noticed yet. So I ring the fire brigade. That is the point where I get involved (the “political act”) rather than being just an observer (a “scientist”). My hope and intention would of course be that the fire brigade comes – but this is not an “agenda”. I do not have any extraneous or prior “agenda” to call the fire brigade, other than the fact that I see a fire and do the only decent and responsible thing.

Now, there could be other people who do have a prior agenda – let’s say a loony who loves fire brigades and wants to see one. Such a person with an agenda might deliberately exaggerate the fire – perhaps it’s just a harmless one that’s already going out by itself, but he tells the fire brigade that he sees big flames coming out of the roof. That would be dishonest and irresponsible, and the fire brigade should rightly be sceptical about the description that such a person gives of the fire.

The problem with your column is: you are clearly suggesting that we at RealClimate are in the latter categorie. We supposedly have some extraneous “agenda” (though what would that be?) to call for greenhouse gas reduction, hence we are prone to exaggerate the risk of climate change, we are not honest brokers, and our statements about the science should be mistrusted.

I’d like to tell you that I simply do not have any “agenda” to reduce greenhouse gas emissions, other than the scientific evidence that I openly discuss. If climate change turned out to be harmless after all, I’d be relieved that we don’t need to reduce emissions. Climate is not an argument that I conveniently use to push some other political agenda of mine. I see myself in the first category of person: I see a fire and I describe it as well as I can to the fire brigade. I have no reason to exaggerate, and the fire brigade has no reason to distrust my information.

If you think that I have moved into the second category, the category of people who might distort information to suit their agenda, the people who may not be fully honest and should not be trusted – then please give the specific evidence for this. This would be a very serious allegation indeed, it would undermine my public credibility, and I would treat this as a very serious issue if you were making such a public allegation about me. I think you owe me a clarification here.

Final point: you claim that RealClimate exlusively focusses on rebutting the arguments of climate contrarians. That is not the case; see e.g. the post I cowrote with Gavin: http://www.realclimate.org/index.php?p=115 “11ºC warming, climate crisis in 10 years?” which rebuts some alarmist media reports. It is true, however, that by far the most (and most systematic and deliberate) distortion of the scientific facts comes from “contrarians”.

Thanks much for your very thoughtful comments. My claims about RealClimate are based empirically, i.e., based upon what I read on the site. I’ll admit to treating the authorship as a single entity (i.e., RealClimate) in my critiques, though I accept your point that there is likely a diversity of views among its contributors. When I read the site, from the main posts to the many comments, I do not see the center of discussion or selction of topics to be on science (as one might expect on such a highly politicized subject, contrary to astrophysics, but not unlike stem cell research). And as I’ve written elsewhere, I don’t think that such efforts should try to be about only science, because any effort to explain the significance of science to the public, journalists or policy makers is a political act (and that is a good thing!). But in my view the only way to serve as an honest broker on science is not to pretend that you are focused only on science, but to openly discuss the significance of science for action.

Thanks for your comments. To be clear, I haven’t made any claim of “intellectual dishonesty”. Clearly the creators of RealClimate thought that there was a difference between a blog and the journals or else they wouldn’t have set it up, right? Peer-reviewed journals are for a discussion of science among specialists. As I understand it RealClimate has positioned itself as explaining science and its significance not to other scientists but to journalists, decision makers and the public. This would seem to be a big difference from what the journals do. And I agree with you that peer-reviewed journals, in varying degrees, often do go well beyond science (maybe not JOC so much, but arguably Science and Nature, and there are extreme examples like Energy and Environment). And your two examples show that RealClimate has not focused its attention exclusively on one side, so my apologies for repeating that claim (which was accurate at the time). In the future I’ll use the term “mostly”;-) And just to remind any readers about what the basic debate is about — RealClimate claims to focus only on scientific issues. I am convinced that the evidence suggests otherwise, specifically that RealClimate is couching political advocacy in the guise of science. From my perspective this debate matters because if I am correct then despite the noble amitions of RealClimate its claims to focus only on science may do more to politicize science than integrate science with policy.

What you said was that you “… believe that there is plenty of discussion of climate science with no extra-scientific context. Just look at the Journal of Climate ….” So you are making the claim that the journals are somehow free of the intellectual dishonesty which you accuse RealClimate of having. I’m not saying the journals are intellectually dishonest, but nor do I believe that RealClimate is. Again, I ask you what substantive argument you have that RealClimate crosses some threshold that the journals supposedly do not cross? Please don’t repeat your claim that “The site’s focus has been exclusively on attacking those who invoke science as the basis for their opposition to action on climate change.” This is simply innaccurate. See for example: http://www.realclimate.org/index.php?p=115, and http://www.realclimate.org/index.php?p=87

P.S. Too bad we didn’t meet up in Seattle. This discussion is probably better had over dinner and beer.
