Lost at Sea

Thompson et al 2008, writing in Nature, assure their readers, the data before ~1940 and after the mid-1960s are not expected to require further corrections for changes from uninsulated bucket to engine room intake measurements Is there a shred of evidence to support this assertion? There is convincing evidence otherwise – evidence already reported here. […]

Nature "Discovers" Another Climate Audit Finding

In an article in Nature today by Thompson, Kennedy, Wallace and Phil Jones claim: Here we call attention to a previously overlooked discontinuity in the record at 1945, Well, folks, the discontinuity may have been overlooked by Hadley Center, CRU, NOAA and NASA and by the stadiums of IPCC peer reviewers, but it wasn’t overlooked […]

The Parking Lot Effect

An interesting post by regular CA commenter David Smith at Anthony Watts on his results quantifying local microsite effects on a thermometer placed near a parking lot. Interesting to compare this with efforts of Jones, Parker, Peterson etc. to “prove” that site effects don’t matter.

Leopold in the Sky with Diamonds

Radiosonde trends are back in the news. A few days ago, on May 24, 2008, Realclimate reviewed three recent papers: Lanzante and Free (J Clim 2008), Haimberger et al (J Clim 2008) and Sherwood et al 2008, adding a note with the even more recent Allen and Sherwood (2008.) Peter Thorne of Hadley Center stated […]

AR 4 Chapter 6 – "In Press" and "Accepted" Articles

I examined the “In Press” and “Accepted” citations in IPCC AR4 Second Draft Chapter 6 to verify whether Wahl and Ammann 200x had received unusual and special treatment. It definitely did; it’s surprising how much so. There was also a very interesting tendency for IPCC Authors to bend the rules in their own favor.

Wahl and Ammann 2007 and IPCC Deadlines

In a previous post, I’ve observed some oddities in connection with the dating of Wahl and Ammann 2007 and with Schneider’s obfuscation when asked to explain how an article supposedly accepted on March 1, 2006 could cite an article that had not even been submitted until August 2006. (BTW, I note that Journal of Climate […]

The Dog That Didn't Bark

This is the title of a famous Sherlock Holmes story and not intended as a slight to any individual. Take a look at the Review Comments for AR4 Second Draft Chapter 6 online here. While I was reviewing these comments, I noticed that there are no reported comments on chapter 6 from Caspar Ammann, one […]

When Was Wahl and Ammann 2007 "Accepted"?

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 […]

Ohio State Presentation

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 […]

Adjustments in the News

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 […]
