Erice 2009 – A Quick Synopsis

This year’s Erice International Seminar was the 42nd. All recipients received an interesting book of memoirs of the seminars (edited W. Barletta and H. Wegener) from which I’ve scanned two interesting pictures (the pictures in the book were mostly recovered by Bill Barletta, an MIT physicist). The first shows Paul Dirac on the right talking […]

The Lodgepole Pine: A Case Study

Every year, the Statistical Society of Canada has a case study competition for statistics students in Canada. The problem and the data are posted about six months before the annual meeting. Teams of students analyze the problem and then present their results at a poster session at the meetings. One of the two topics for […]

Spline Smoothing

The 2009 Climate Dynamics paper “Unprecedented low twentieth century winter sea ice extent in the Western Nordic Seas since A.D. 1200” by M. Macias Fauria, A. Grinsted, et al. discussed already on the thread Svalbard’s Lost Decades pre-smooths its data with a 5-year cubic spline before running its regressions. There’s been a lot of discussion […]

NASA: Sea Level Update

Yesterday, at 2:07 PM CA time (4:07 PM EDT), Rob Spooner posted the following comment in the Unthreaded n+2 thread: http://www.climateaudit.org/?p=5978#comment-353931 I’ve been asked to move a comment to this thread (or unthread), so here it is. I have run into a small problem with some NASA methodology. Looking at http://climate.nasa.gov/keyIndicators/ and just eyeballing the […]

NAS Report on Data and Methods Disclosure

Jeff Id on the Air Vent has written a post pointing out the recent publication online of a report by the Committee on Ensuring the Utility and Integrity of Research Data in a Digital Age from the National Academy of Sciences: Ensuring the Integrity, Accessibility, and Stewardship of Research Data in the Digital Age. I […]

Svalbard’s Lost Decades

In a 2006 article in JGR, Aslak Grinsted, John Moore, Viejo Pohjola, Tonu Martma and Elisabeth Isaksson study several climate indicators from the Lomonosovfonna ice field in Svalbard, shown below with their caption: Figure 5. Fifteen-year moving averages of Lomonosovfonna ice core data. (a) Oxygen isotopes, (b) continentality proxy (A), (c) stratigraphic melt indices (SMI), […]

Rejected … by RC!

I have been rejected at RealClimate! My first rejection! I have not posted there in about two years although I have occasionally read some of their consensus defences when they were relevant to what I have been looking at. They have been running a Steig Corrigendum thread concurrent with ours and I have followed it […]

Erice 2009

I’m off to Italy for the next two weeks, starting tonight. I suggested that the Erice seminar of the World Federation of Scientists have a session on Water Cycle Feedback, as this seemed to me to be the most important scientific issue affecting climate sensitivity. I had a couple of motives for suggesting this – […]

Steig Professes Ignorance

On Feb. 26, I wrote a post on CA, “Steig 2009’s Non-Correction for Serial Correlation”, commenting on the Jan. 22 letter in Nature by Eric Steig et al. On Feb. 28, I sent Steig and his 5 co-authors an e-mail alerting them to my post and its content. On Aug. 6, Steig and co-authors published […]

Steig and the International Man of Mystery

Real Climate has defended Steig against a plagiarism complaint from Hu McCulloch, covered by Pielke Jr here and Jeff Id here. Hu’s original post is here and the most recent CA discussion here. Hu’s complaint is here. Note: Hu’s email to the Steig coauthors is here. Steig was not the only recipient. All Steig authors […]
