Some links for the bunnies
Magnus Westerstrand discusses the hidden Bengtsson and his media gambit.
I am sad to have witnessed the changes in Lennart Bengtsson's media presence over the last few years. At first it was just a few comments in local media such as this article in UNT 2009 stating among other things that a doubling of carbon dioxide in the atmosphere would only result in a temperature increase of about 1 oC as a result of the logarithmic forcing of CO2. This is misleading, of course, because it ignores feedbacks which increase that number substantially. He even admits in his comment, that this could be taken as a way of playing down the problem, but at the same time he writes that it should provide perspective.
Thomas Stocker discusses how climate scientists are being intimidated by the deniers.
Prof Thomas Stocker, Swiss-born co-chairman of the panel’s working group on the scientific basis for climate change, said the campaign to undermine its fifth assessment report was led by “people and organisations with vested interests”.An interesting comment from Thomas Piketty on the nature of real world data, not about climate, but IEHO it applies none the less.
For the time being, we have to do with what we have, that is, a very diverse and heterogeneous set of data sources. . . . I have no doubt that my historical data series can be improved and will be improved in the future. . . . but I would be very surprised if any of the substantive conclusions about the long run evolution . . . . was much affected by these improvements.The details may differ, but the substantive conclusions have remained the same over a very long time.
The Weasel, has lifted some comments from Andy Lacis which explains this as well as an appreciation of L'Affaire Bengtsson.
And Andrew Gelman has been dipping into econometrics. He and those who comment at his blog have a few questions. They are not impressed with Richard Tol's answers.
