  • 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.”
  • Economics Behaving Badly — A great NYT article on behavioural economics & its failings, important for climate policy.
  • Institute of Physics disbands Energy Sub-Group following ‘skeptical’ ClimateGate submission — Hopefully the end of the embarrassment for the IoP.

  • Scientists hash out the uncertainties of climate sensitivity — Here’s some great science journalism, climate sensitivity made fun (almost!).
  • Methane bubbling out of Arctic Ocean – but is it new? Great piece by New Scientist on the Arctic permafrost and the uncertainties inherent in any ‘new’ scientific discovery.
  • Debunking Lomborg, the Climate-Change Skeptic — Turns out Bjorn Lomborg really is the T-2000 of climate denial world: younger, smarter, stronger, more sophisticated. But essentially still a destructive machine sent from the future…
  • Texan Scientists: On global warming, the science is solid — We need more scientists doing this sort of thing, regional and local newspapers are really important!

  • 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.”
  • Overview of all the ‘Gates — very useful brief run-down of the last 4 months.
  • 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…

GrowthGate0

Via Tamino at OpenMind:
Suppose you have a child, a son — he’s 10. You want to know whether or not he’s growing normally, so every day you measure his height with a tape measure. You’ve done so since he was 5. You even plot the data on a graph, and notice two things about it. First: the measurements show a fair amount of jitter, sometimes they’re a wee bit higher, sometimes a wee bit lower, there’s noise in the data. Second: there’s also a trend. Your kid is a lot taller at 10 than he was at 5, in fact the trend over the observed time span is upward and reasonably steady. You even do a statistical analysis, estimate the growth rate, and determine that it’s definitely statistically significant — so it’s not a false trend due to noise in the data, it’s real. Your son is growing normally.

Then you’re interviewed by a reporter from the Daily Mail. He asks, “Can you prove — with statistical significance — that your child has been growing since last Tuesday?”
