And yet it works. Adam Corner on ‘ClimateGate’, transparency & peer-review. – “Open access is based on the premise that there are those outside the inner circle of peer reviewers who are competent enough to provide a second opinion on the science. This is indisputably true. But while talk of throwing open the lab doors might be rhetorically satisfying, it would provide only an illusion of democracy. Certainly there are non-academics competent enough with statistics to find errors in a piece of published science. Correcting errors in science would be a valuable service for an auditor to offer. But if several auditors reached conflicting conclusions, then somehow a judgement would have to be made about their respective competence. And who should make that judgement? Presumably a group of suitably qualified, honest individuals with a proven track record in a relevant discipline – in other words, peer review.”
Climate email inquiry: bringing democracy to science | Richard Horton – “Scientists need to do more to emphasise their uncertainties, not recoil from them. Uncertainty may be uncomfortable, but its admission builds trust. It demonstrates integrity. One of science’s great strengths is its quantification of doubt. Fourth, scientists need to take peer review off its pedestal. As an editor, I know that rigorous peer review is indispensable. But I also know that it is widely misunderstood. Peer review is not the absolute or final arbiter of scientific quality. It does not test the validity of a piece of research. It does not guarantee truth. Peer review can improve the quality of a research paper – it tells you something about the acceptability of new findings among fellow scientists – but the prevailing myths need to be debunked. We need a more realistic understanding about what peer review can do and what it can’t. If we treat peer review as a sacred academic cow, we will continue to let the public down again and again.”
Black Carbon’s Grey Areas – A brilliant, must-read article on black carbon. Who would have thought it has such broad geopolitical implications? Worth the effort. It’s conclusions: 1. Stop throwing cook-stoves at the problem. 2. Target diesel. 3. Be very careful about comparing black carbon with carbon dioxide.
Arctic climate may be more sensitive to warming than thought – “Our findings indicate that CO2 levels of approximately 400 parts per million are sufficient to produce mean annual temperatures in the High Arctic of approximately 0 degrees Celsius (32 degrees F) [19 degrees Celsius warmer than today!],” Ballantyne said. “As temperatures approach 0 degrees Celsius, it becomes exceedingly difficult to maintain permanent sea and glacial ice in the Arctic. Thus current levels of CO2 in the atmosphere of approximately 390 parts per million may be approaching a tipping point for irreversible ice-free conditions in the Arctic.”
Troubling ice melt in East Antarctica – it’s losing mass, which is not good. – “It’s too early to know what the ice loss in East Antarctica really means, says Isabella Velicogna, a remote-sensing specialist at NASA’s Jet Propulsion Laboratory in Pasadena, California. “What is important is to see what’s generating the mass loss,” she says. Reductions in snowfall, for example, might reflect short-term weather cycles that could reverse at any time. But thinning caused by accelerating glaciers—as seen in West Antarctica—would warrant concern.”
Peru inventor ‘whitewashes’ peaks to slow glacier melt – In a remote corner of the Peruvian Andes, men in paint-daubed boilersuits diligently coat a mountain summit with whitewash in an experimental bid to recuperate the country’s melting glaciers. Peru’s Environment Minister Antonio Brack has said the World Bank’s 200,000 dollars in funding would be better spent on other “projects which would have more impact in mitigating climate change.” “It’s nonsense”, he commented bluntly last year.
Leakegate: A retraction – “It is an open question as to what impact these retractions and apologies have, but just as with technical comments on nonsense articles appearing a year after the damage was done, setting the record straight is a important for those people who will be looking at this at a later date, and gives some hope that the media can be held (a little) accountable for what they publish.”
And finally, on a slight tangent:
Ben Goldacre: Yeah well you can prove anything with science – “When presented with unwelcome scientific evidence, it seems, in a desperate bid to retain some consistency in their world view, people would rather conclude that science in general is broken. This is an interesting finding. But I’m not sure it makes me very happy.”
Matthew Nisbet over at Framing Science has an excellent blog post on the potential over-reaction by climate scientists to the events of the last few months. The piece is written from a US perspective, but I think it applies equally here in the UK. He notes:
Multiple surveys show a decline in public concern with climate change and it”s clear that political momentum for policy action has stalled. But there are several likely causes, the direct efforts of the climate skeptic movement just one of them, and probably one of the more minor causes.
These other factors include the economy, confusion over colder weather and other perceptual biases, general distrust of government, climate policies such as cap and trade that are not easily sold as effective or in line with public values, the absence of strong Presidential leadership on the issue, institutional barriers in Congress and at the international level, and the continued belief by some scientists and advocates that public support and policy action will turn on science rather than on a calculation of values and trade-offs.

SealevelGate – Real Climate cover the true IPCC sea-level scandal. Must read.
Climate of fear, Nature editorial (free access) – “The integrity of climate research has taken a very public battering in recent months. Scientists must now emphasize the science, while acknowledging that they are in a street fight.”
Short must read: Climate Change and the Media – “What’s truly infuriating about this episode of journalistic malpractice is that, once again, it illustrates the reasons why the East Anglia scientists adopted an adversarial attitude towards information management with regard to outsiders and the media. They were afraid that any data they allowed to be characterised by non-climate scientists would be vulnerable to propagandistic distortion. And they were right.”
A brief summary of the Science & Technology Committee”s “ClimateGate” hearing
The House of Commons Science and Technology Committee met yesterday for a one off evidence session looking at the disclosure of climate data from the Climatic Research Unit at the University of East Anglia. This blog post is a brief summary of the key issues. [Apologies for the use of some jargon that crops up because of the nature of the CRU emails.]
Lord Lawson and Dr Benny Peiser were first up. They represent the Global Warming Policy Foundation who, amusingly, failed to plot 8 temperature values correctly in their logo – I”m not sure that this gives them the authority to question 25 years of academic research on climate data but let”s see what they had to say… Read more
Following the UEA email hack, it’s become part of the media narrative that opinion is turning against man-made global warming. It’s usually worth checking any such media claim about changes in public opinion that have supposedly occurred following a series of news stories, particularly ‘dramatic revelations’. Read more
In the wake of the “Climategate” affair – the illegal hacking and publication of a huge number of emails from the University of East Anglia’s Climatic Research Unit – I’ve been trying to put together some “points to remember” on the episode, along with some of the key points of evidence. Below is what I’ve managed to come up with. Owing to the story’s media profile, the volume of material out there is now pretty enormous and somewhat unwieldy. Nevertheless, I hope this at least begins to cover most the bases, and will generally be of some use. Read more
