Some readers may have noticed a Dutch scandal in the academic psychology industry. See here (h/t Pielke Jr). The previously undisclosed whistleblower is said to be Uri SImonsohn, co-author of the article: “False-Positive Psychology: Undisclosed Flexibility in Data Collection and Analysis Allows Presenting Anything as Significant.” The authors set out the following sensible solution to […]
Geoffrey Boulton, who did an execrable job on the Muir Russell “inquiry”, has written a good editorial in Nature here reporting on the recent Royal Society report that he chaired. There have been a number of reports over the years, urging improved data archiving, and yet the problems persist. Boulton’s report is merely one more. […]
My sister sent me the following picture of the Colorado Springs fire. It’s about 10 miles from their house. CA commenter Pete H (also author of the handy WordPress unthreading plug-in and one of the major behind-the-scenes technical helpers to the blog) also lives in Colorado Springs.
Myles Allen recently asked that more attention be paid by critics to work on climate sensitivity, rather than paleoclimate. Nic Lewis, a coauthor of O’Donnell et al 2010, has been parsing climate sensitivity calculations for some time and with considerable frustration. Nic Lewis has a very important article at Judy Curry’s here. One of the […]
Although Geoffrey Boulton was the lead author, the Royal Society report on data sharing published today was surprisingly even handed. (h/t Bishop Hill.) Climate Audit and McIntyre S receive a cameo mention on page 40: At the other extreme, there is a small, but increasingly numerous body of engaged “citizen scientists” that wish to dig […]
There has been a great deal of discussion on a recent CA thread on the efficacy of screening proxies for use in reconstructions by selecting on the size of the correlation between the proxy and the temperature during the calibration time period. During the discussion I asked Nick Stokes the following questions in a comment: […]
Oxygen isotope series are the backbone of deep-time paleoclimate. The canonical 800,000 year comparison of CO2 and temperature uses O18 values from Vostok, Antarctica to estimate temperature. In deep time, O18 values are a real success story: they clearly show changes from the LGM to the Holocene that cohere with glacial moraines. On its face, […]
First, let’s give Gergis, Karoly and coauthors some props for conceding that there was a problem with their article and trying to fix it. Think of the things that they didn’t do. They didn’t arrange for a realclimate hit piece, sneering at the critics and saying Nyah, nyah, what about the hockey stick that Oerlemans […]
In a figure that took considerable work, IPCC AR5 (First Draft) compared 5 regional proxy reconstructions to model output. In Australia, they used the Gergis (Neukom) et al 2012 reconstruction, In South America, they used a Neukom et al 2011 (Clim Dyn) reconstruction. In 2011, Neukom refused to provide me with the data versions used […]
A few days ago, Joelle Gergis closed her letter refusing data stating: We will not be entertaining any further correspondence on the matter. Gergis’ statement seems to have been premature. David Karoly, the senior author, who had been copied on Gergis’ surly email and who is also known as one of the originators of the […]
