This post got deleted in the server crash. I typically post up from written text, but usually do a final edit as I input onto the blog, so the present note will probably differ a little from what I posted up yesterday, but probably not materially. Mann did not present anything germane that had not […]
As you’ve noticed, there was a server crash and the site has been restored from a back-up. I’m told that the site is on a new server. The recurrent down-time leading up to the crash was presumably related. Lost in the backup are my post on Mann at the NAS panel, my update to the […]
Reader Bart S. has argued that Cook et al [QSR 2004] disposed of the "Divergence Problem", the name applied at the NAS panel on March 2-3, 2006 for the problem that, if the proxies do not record late 20th century warming, how can we be sure that they recorded potential earlier warming in the MWP. […]
Otto-Bliesner asked me how I would do a reconstruction. As I’ve said on other occasions, I said that I didn’t know. I’m really reluctant to just apple-pick some series but it’s prbably worthwhile showing that you can pick apples as well as cherries. More constructively, I think that there are some approaches that look better […]
Back to reporting on our presentation to the NAS panel, after which I’ll report on Mann. We presented last in the day, immediately following von Storch. Hughes and Mann presented on Friday morning. We gave them a long written presentation, and touched the high points in our PPT, also providing them with a CD of […]
If you glance to the bottom of the sidebar on the right hand side, you will find a brand new, shiny, and in keeping with CA’s overriding philosophy, free visitor counter with the added bonus that we can then all view where you’re browsing from. Over time you’ll see that we get visitors, trolls and […]
A propos of nothing, I decided to check out the statistics provided by the webhost (Webserve.ca) on climateaudit.org, since we didn’t know whether the recent statistics were an aberration or a short sample from a long trend. Using advanced statistical analysis tools (OpenOffice Calc) and image transformation technologies (Krita) I present the real statistics of […]
One of the concerns that people are increasingly expressing to us in reaction to demonstrations of methodology problems in Hockey Team multiproxy studies is more or less this: even if the methods used in these various studies are flawed from the point of view of a statistical purist, no one’s presented an alternative interpretation of […]
The minutes for the NAS Panel here includes a reading list. They provide citations for each of the PPT presentations, including ours. They mention a “handout” and “CD” from us. The “handout” was a formal written presentation to the panel, setting out the points in our PPT. It deserves a citation. I wonder whether they […]
Here’s a summary (archive)from Science of last week’s NAS panel. The heat was on a 12-person National Research Council committee last week as it tackled the politically charged debate over how scientists have gauged temperatures from the past millennium or two. Chair Gerald North of Texas A&M University in College Station kept the audience on […]
