Consensus as the New Heresy

by

Gavin Schmidt, Michael Mann, David Archer, Stefan Rahmstorf, William Connolley, and Raymond Bradley

Andy Revkin, who’s one of the best journalists on the climate beat, wrote a curious piece in the NY Times discussing the ‘middle stance’ of the climate debate. It’s nice to see news pieces on climate that aren’t breathless accounts of a new breakthough and that take the time to point out that the vast majority of relevant scientists take climate change extremely seriously. To that extent, the message of this piece was a welcome one. The curious part, however, was the thread running through the piece that this middle ground is only now emerging, and even curiouser, that this middle ground can be characterized as representing some sort of ‘heresy’.

Heresy, is commonly defined as ‘an opinion or doctrine at variance with the official or orthodox position’. So where does this idea come from, and why is it now ’emerging’?

Inhofe’s last stand

by

Part of me felt a little nostalgic yesterday watching the last Senate hearing on climate change that will be chaired by Sen. James Inhofe. It all felt very familiar and comforting in some strange way. There was the well-spoken ‘expert’ flown in from Australia (no-one available a little closer to home?), the media ‘expert’ from the think tank (plenty of those about) and a rather out-of-place geologist. There were the same talking points (CO2 leads the warming during the ice ages! the Medieval Warm Period was warm! it’s all a hoax!*) that are always brought up. These easy certainties and predictable responses are so well worn that they feel like a pair of old slippers.

Broadly Misleading

by

Just when we were beginning to think the media had finally learned to tell a hawk from a handsaw when covering global warming (at least when the wind blows southerly), along comes this article ‘In Ancient Fossils, Seeds of a New Debate on Warming’ by the New York Times’ William Broad. This article is far from the standard of excellence in reporting we have come to expect from the Times. We sincerely hope it’s an aberration, and not indicative of the best Mr. Broad has to offer.

Broad’s article deals with the implications of research on climate change over the broad sweep of the Phanerozoic — the past half billion years of Earth history during which fossil animals and plants are found. The past two million years (the Pleistocene and Holocene) are a subdivision of the Phanerozoic, but the focus of the article is on the earlier part of the era. Evidently, what prompts this article is the amount of attention being given to paleoclimate data in the forthcoming AR4 report of the IPCC. The article manages to give the impression that the implications of deep-time paleoclimate haven’t previously been taken into account in thinking about the mechanisms of climate change, whereas in fact this has been a central preoccupation of the field for decades. It’s not even true that this is the first time the IPCC report has made use of paleoclimate data; references to past climates can be found many places in the Third Assessment Report. What is new is that paleoclimate finally gets a chapter of its own (but one that, understandably, concentrates more on the well-documented Pleistocene than on deep time). The worst fault of the article, though, is that it leaves the reader with the impression that there is something in the deep time Phanerozoic climate record that fundamentally challenges the physics linking planetary temperature to CO2. This is utterly false, and deeply misleading. The Phanerozoic does pose puzzles, and there’s something going on there we plainly don’t understand. However, the shortcomings of understanding are not of a nature as to seriously challenge the CO2.-climate connection as it plays out at present and in the next few centuries.

Sachs’ WSJ Challenge

by

Jeffery Sachs of the Columbia Earth Institute has an excellent commentary in Scientific American this month on the disconnect between the Wall Street Journal editorial board and their own reporters (and the rest of the world) when it comes to climate change. He challenges them to truly follow their interest in an “open-minded search for scientific knowledge” by meeting with the “world’s leading climate scientists and to include in that meeting any climate-skeptic scientists that that the Journal editorial board would like to invite”.

RealClimate heartily endorses such an approach and, while we leave it to others to judge who the ‘world leading’ authorities are, we’d certaintly be willing to chip in if asked. To those who would decry this as a waste of time, we would point to The Economist who recently produced a very sensible special on global warming and proposed a number of economically viable ways to tackle it, despite having been reflexively denialist not that many years ago. If the Economist can rise to the challenge, maybe there is hope for the Wall Street Journal….

Chinese whispers in Australia

by

We decided months ago that we would not comment on leaks of the draft of the upcoming IPCC report (due Feb 2007) but we are prepared to correct obvious errors. The ongoing revisions of the text and the numerous drafts make any such commentary, let alone conclusions drawn from it, pretty pointless. This is even more true when the leaks are obviously confused about a central point. The principle error in the latest ‘exclusive’ is that the writer confuses a tightening of the estimate of climate sensitivity to 2xCO2 (as discussed here) with projections of climate change in 2100. These projections obviously depend on the uncertainties in the scenarios of future technology, economic progress and population (etc.) plus uncertainties in feedbacks related to the carbon or methane cycles. Unfortunately these have not been reduced since the last assessment report (and in some cases have actually increased).

That occasional stories will come out that get basic things wrong is unfortunate but not surprising. What is more troubling is that they subsequently get picked up by Reuters and UPI, and republished in places (such as Scientific American, though in their defence, it is simply a posting of the wire report) where the editors should know better. Worse still, the wire service stories are too brief to make the source of the error obvious, and thus the error gets propagated in an ever more confused state. As usual the blogsphere is playing a key role in amplifying and further muddying the story. The advantage of blogs is that errors can be corrected quickly, and the comments on Prometheus for instance, quickly revealed the confusion and the potential agenda of the original story.

There will be plenty of time to discuss the new IPCC report when it comes out and where everyone can read for themselves what has and what hasn’t changed since 2001. Until then, we would counsel against journalists and editors jumping at supposed ‘exclusives’ and – more dangerously – going ahead with them without even a basic sanity check of the details.

Nature’s press advisories

by

Articles in Nature (or Science) are embargoed for the media until the day of publication. A week before publication, Nature sends out a press advisory describing the week’s upcoming papers that is separate from any press releases that the authors or their institutions might put out. Journalists read these, and if interested, spend the time before the actual publication talking to sources and doing background so that they have (hopefully) well-thought out stories ready to go when the embargo lifts. The resulting media splash for the most interesting papers is usually good for the magazine and the authors. But not always.

Last week, the press advisory for one paper gave a slightly misleading account of one apsect of the work described in the article. Normally this would probably not get much attention, but the paper in question dealt with the highly emotional and politicized topic of stem cell research. I don’t want to get into the specifics of this paper (comments on that should be directed elsewhere) but the New York Times reported on the clarification that Nature subsequently put out and noted that the principal author Robert Lanza, had neither seen nor approved the text of the press advisory.

This might seem strange, but this is actually the normal state of affairs. Nature‘s editors write the advisories, which only go out to journalists and are not in general ever seen by the public. Often though, these short blurbs set the tone for the subsequent media attention but, if there is a problem, it can lead to a very widespread mis-communication. Colleagues of mine have been in the odd position of having to ask the journalists to read out the release concerning their own work!

We have previously discussed the problems of getting the press release just right when dealing with articles on potentially controversial science topics, and we strongly urged scientists to be more aware of how press releases are crafted and the message they send. This is obviously very difficult to do if the scientists are not involved in the process.

Coincidentally, I recently had a casual conversation with one of the Nature editors concerning this exact issue (prior to last week’s kerfuffle) and learned that the magazine was thinking about making the advisories public at the time of publication. This would definitely be a step forward for openness. I would go further and also suggest that the principal authors be given a chance to comment on the advisories before they go out. Getting things wrong – even subtly – in contentious fields doesn’t help anyone and the slight extra effort to try and prevent mis-communication is well worth it.

In a similar vein, I have found that journalists who take the time to check back with scientists on their quotes or explanations of the science often catch ambiguities or errors at an early stage and this should be encouraged as much as possible.

At a time when science and science reporting is under pressure from many quarters, journals, press officers, editors and authors need to work more closely together on ensuring that science is reported accurately and effectively.

New public opinion poll on global warming

by

There is a new Zogby poll on public attitudes in the US towards global warming and the potential connection between severe weather events and climate change.

Unsurprisingly to us (but maybe not to others), most of the US public feel that global warming is happening (around 70%), and roughly the same amount of people report being more or much more convinced of this over the last two years.

More interestingly, the pollsters asked whether people believed that global warming was having an effect on intense hurricanes, droughts, heat waves and the like. Again, roughly 70% of people thought that global warming was having either some effect or a major effect on these weather extremes (note that the question was not phrased to ask whether any specific event was thought likely to have been caused by global warming (which was probably a good choice)).

This begs the question whether people’s experience of severe weather has convinced them that climate change is occuring. Televangelist Pat Robertson, for instance, said very recently that it was the latest heat wave that finally convinced him. I think this is likely to be true for most of the public who are not following the issue very carefully (which is most of them of course!). The most significant single event in this context was probably Katrina, regardless of how much climate change can or can’t be associated with Katrina the Hurricane (let alone Katrina the Disaster!).

I would guess that this is likely to be a very common way for public opinion to be formed across a whole number of issues. That is, when a dominant theme is very prevalent across a wide spectra of media, everyday occurrences or new information are often processed with that in mind, and given our extraordinary ability to see patterns in noisy data, we often end up associating the theme with our own experiences. Other examples surely abound in medical or political contexts.

Given that pattern, it is probably overly optimistic to expect scientists, who continually stress that single weather events can’t in general be attributed to climate change but that changes in statistics might be, to have much success in conveying these finer points to the public directly. Instead, their skills are probably best used in clarifying these points to those (e.g. journalists, policy-makers) that set the dominant themes in the first place.

The missing repertoire

by

There was a small flurry of activity last week when the report “Warm words: How are we telling the climate story and how can we tell it better?” was released by the IPPR (a UK based left-leaning think tank). Most of the attention was focussed on their attention-seeking description of the more breathless media depictions of climate change as ‘climate porn’. However, the report was actually more interesting than just that, but possibly in ways that the authors didn’t intend.

Disinformation? You want it, IREA’s got it

by

RealClimate received a copy of a letter from the General Manager of the Intermountain Rural Electric Association (IREA, an energy cooperative in Colorado), Stanley R. Lewandowski (Jr), to other utilities (G&T’s in the jargon) in the US discussing fundraising and tactics for a new disinformation campaign on climate change (see Seth Borenstein’s piece yesterday).

This is enlightening on a number of levels. Firstly, though we knew that this stuff goes on, it’s rare that we get such a close look at how it happens. Secondly, who is to be the lead on this new campaign? None other than our old friend Patrick Michaels. Additionally, it is useful to see the reasons why some utilties are fighting against the idea of climate change set out more clearly than in their more carefully manicured press briefings. It might actually help people engage on the substance of their concerns rather than simply arguing about the science – which, as we are by now well aware, – is simply a path to gridlock.

We’ll highlight some of the best bits, and discuss what this all might imply below. [Read more…] about Disinformation? You want it, IREA’s got it
