Last summer, on Aug 28, 2007, I wrote a post observing that Wahl and Ammann 2007, although being cited in IPCC AR4, had still not appeared in print. I think that it was then the only article cited in IPCC AR4 chapter 6 in that situation. In that post, I observed that it seemed anomalous […]
In my post The Accidental Tourist I discussed the relationship between the Russian Meteo daily temperature record for Kurgan and two of the GHCN records for that same weather station. One surprise I learned was that GHCN discarded an entire month’s worth of data when a single data point was suspect. Doing so left GISS […]
I’ve posted my Ohio State presentation online – 11 MB. I’ve done a little extra work and integrated the PPT pictures with the script and provided most of the references in a bibliography. There’s quite a lot of material, but I hit my time point (an hour) quite accurately. (A reader compressed this to 1 […]
We discuss adjustments a lot on this blog. Today there’s a remarkable example and brewing scandal involving first a computer error in which Moody’s incorrectly graded certain debt obligations. The real story comes after the problem was identified – as it is alleged that Moody’s altered its models to avoid having to fully undress its […]
Occasionally I will take a trip after much careful planning and preparation, only to find myself going off into uncharted territory soon after embarking on my adventure. That is what happened to me recently when I started to take a fresh look at worldwide station coverage. Where I ended up and what I found when […]
At Steve Mosher’s request, a thread for the revived effort to compile Gistemp.
Zotero is a Firefox add-on that, within the browser, can capture academic citations from Google Scholar, many library catalogues and multiple other sources. It permits you to insert links to the pdfs (both external and on your own directory) and go to them within the browser, to add your own cross-reference tags and notes. I […]
As Hu McCulloch mentioned, I am speaking tomorrow, Friday May 16, at OSU on “Was 1998 the Warmest Year of the Millennium: What do We Really Know?” The talk will be 2:30-3:48 in Scott Lab 001 (a big lecture hall in the basement of the south end of the east wing). A reception will follow. […]
Anything by Demetris Koutsoyiannis is always worth spending time on. Spence_UK draws our attention to this recent presentation at AGU asking: How well do the models capture the scaling behaviour of the real climate, by assessing standard deviation at different scales. (Albeit at a regional, rather than global level). Assessment of the reliability of climate […]
Steve Mosher provides the following recipe for getting GISS Model E results: Ok getting ModelE data Start here http://data.giss.nasa.gov/ See the link for climate simulations of 1880-2003. click that http://data.giss.nasa.gov/modelE/transient/climsim.html Here you will see the link to the paper and all the readme I know of now to get the data look at table 1.
