  • 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.

Dive right in:

  • Will 2010 be the hottest year on record? – it all depends on which data source you choose: GISTEMP (likely) or HadCRU (about as likely as not).
  • Climate change is leaving us with extra space junk – Even the space junk is trying to tell us we’re changing the climate. One more independent line of evidence to add to the pile, how many do we need?!
  • 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.
  • Ocean acidification – still happening.
  • 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.”
  • Network Rail study to assess impact of climate change – eco-stealth taxes are being used to… strengthen our vulnerable rail network, oh.
  • 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.”

  • Climate Change: A Threat to Global Security. US & UK Defense agree. – “I am struck by how similar UK and U.S. thinking is on the national security implications of climate change. Our defense departments agree that the impact of climate change is likely to be most severe in areas where it coincides with other stresses, such as poverty, demographic growth, and resource shortages: areas through which much of the world’s trade already passes.”
  • A Superstorm for Global Warming Research – a terrible terrible piece from Der Spiegel, who are usually pretty good at science reporting. Two of the authors have previously written some very misleading and inaccurate articles on climate change. Watch this space for updates…
  • Visualizing Arctic Sea Ice Extent Trends – “If you find yourself asking “what about … or what happens when…”, it’s probably time to make another chart that directly addresses your new “compared to what” question. Don’t expect one chart to answer multiple questions.”
  • Arctic ice recovers from the great melt – Wow, a semi-decent piece by Jonathan Leake! Apart from wrongly attributing the recent ‘spurt’ in ice growth to the Arctic Oscillation (it was more likely just a response to changes in regional atmospheric circulation) it’s a measured and almost insightful piece… is something weighing on his mind perhaps?
