There is a lot of talk around about why science isn’t being done on blogs. It can happen though, and sometimes blog posts can even end up as (part of) a real Science paper. However, the process is non-trivial and the relatively small number of examples of such a transition demonstrate clearly why blog science is not going to replace the peer-reviewed literature any time soon.
Climate Science
O’Donnellgate
or…Some thoughts on Personal Responsibility and the Peer Review Process
Eric Steig
Ryan O’Donnell made a series of serious of allegations against me at ClimateAudit, in the context of our friendly dispute about whether his new paper in the Journal of Climate supports or ‘refutes’ my own results, published in Nature.
To his credit, Ryan has offered to retract these allegations, now that he is a little better acquainted with the facts. However, it is still important, I think, to set the record straight from my point of view. There were such a great number of claims about my “dishonesty,” “duplicity” and [implied] stupidity, all of which are untrue, that it really isn’t worth trying to respond in any detail. Just responding to the main two ought to suffice to make the point. [Read more…] about O’Donnellgate
The Starship vs. Spaceship Earth
Eric Steig & Ray Pierrehumbert
One of my (Eric’s) favorite old books is The Starship and the Canoe by Kenneth Brower It’s a 1970s book about a father (Freeman Dyson, theoretical physicist living in Princeton) and son (George Dyson, hippy kayaker living 90 ft up in a fir tree in British Columbia) that couldn’t be more different, yet are strikingly similar in their originality and brilliance. I started out my career heading into astrophysics, and I’m also an avid sea kayaker and I grew up with the B.C. rainforest out my back door. So I think I have a sense of what drives these guys. Yet I’ve never understood how Freeman Dyson became such a climate contrarian and advocate for off-the-wall biogeoengineering solutions like carbon-eating trees, something we’ve written about before.
It turns out that Brower has wondered the same thing, and in a recent article in The Atlantic, he speculates on the answer. “How could someone as smart as Freeman Dyson,” writes Brower, “be so wrong about climate change and other environmental concerns..?”

West Antarctica: still warming
The temperature reconstruction of O’Donnell et al. (2010) confirms that West Antarctica is warming — but underestimates the rate
Eric Steig
At the end of my post last month on the history of Antarctic science I noted that I had an initial, generally favorable opinion of the paper by O’Donnell et al. in the Journal of Climate. O’Donnell et al. is the peer-reviewed outcome of a series of blog posts started two years ago, mostly aimed at criticizing the 2009 paper in Nature, of which I was the lead author. As one would expect of a peer-reviewed paper, those obviously unsupportable claims found in the original blog posts are absent, and in my view O’Donnell et al. is a perfectly acceptable addition to the literature. O’Donnell et al. suggest several improvements to the methodology we used, most of which I agree with in principle. Unfortunately, their actual implementation by O’Donnell et al. leaves something to be desired, and yield a result that is in disagreement with independent evidence for the magnitude of warming, at least in West Antarctica.
In this post, I’ll summarize the key methodological changes suggested by O’Donnell et al., discuss how their results compare with our results, and the implications for our understanding of recent Antarctic climate change. I’ll then try to make sense of how O’Donnell et al. have apparently wound up with an erroneous result.

Friday round-up
A few items of interest this week.
Paleoclimate:
1. A new study by Spielhagen and co-authors in Science reconstructs temperatures of North Atlantic source waters to the Arctic for the past two millennia, adding another very long-handled Hockey Stick to the ever-growing league.
2. From last week, an article in Science Express by Buntgen et al reconstructing European summer temperature for the past 2500 years, finding that recent warming is unprecedented over that time frame, and providing some historical insights into the societal challenges posed by climate instability (listen here for an interview with mike about the study on NPR’s All Things Considered).
3. The team of ice core researchers at WAIS Divide reaches its goal of 3300 meters of ice. [WAIS Divide, central West Antarctica, is a site of significant warming in Antarctica, over at least the last 50 years, a result recently confirmed by the study of O’Donnell et al. (2010); Stay tuned for more on the that soon].
Other Miscellaneous Items:
1. More in Nature on data sharing.
2. A great primer in Physics Today on planetary energy balance from our very own Ray Pierrehumbert (link to pdf available here).
3. Now shipping are David and Ray’s The Warming Papers and Ray’s Principles of Planetary Climate.
2010 updates to model-data comparisons
As we did roughly a year ago (and as we will probably do every year around this time), we can add another data point to a set of reasonably standard model-data comparisons that have proven interesting over the years.

Getting things right
Last Monday, I was asked by a journalist whether a claim in a new report from a small NGO made any sense. The report was mostly focused on the impacts of climate change on food production – clearly an important topic, and one where public awareness of the scale of the risk is low. However, the study was based on a mistaken estimate of how large global warming would be in 2020. I replied to the journalist (and indirectly to the NGO itself, as did other scientists) that no, this did not make any sense, and that they should fix the errors before the report went public on Thursday. For various reasons, the NGO made no changes to their report. The press response to their study has therefore been almost totally dominated by the error at the beginning of the report, rather than the substance of their work on the impacts. This public relations debacle has lessons for NGOs, the press, and the public.

Reflections on funding panels
Despite what is often claimed, climate scientists aren’t “just in it for the money”. But what scientists actually do to get money and how the funding is distributed is rarely discussed. Since I’ve spent time as a reviewer and on a number of panels for various agencies that provide some of the input into those decisions, I thought it might be interesting to discuss some of the real issues that arise and the real tensions that exist in this process. Obviously, I’m not going to discuss specific proposals, calls, or even the agencies involved, but there are plenty of general insights worth noting.

Forbes’ rich list of nonsense
Guest commentary from Michael Tobis and Scott Mandia with input from Gavin Schmidt, Michael Mann, and Kevin Trenberth
While it is no longer surprising, it remains disheartening to see a blistering attack on climate science in the business press where thoughtful reviews of climate policy ought to be appearing. Of course, the underlying strategy is to pretend that no evidence that the climate is changing exists, so any effort to address climate change is a waste of resources.
A recent piece by Larry Bell in Forbes, entitled “Hot Sensations Vs. Cold Facts”, is a classic example.
