Day Three – AGU

My notes are going to be quick as I’m off in a half hour.

Day Two at AGU

It is impossible to convey the overwhelming number of papers and presentations here. Through the week, my notes have invariably deteriorated. By the time you get home, they are unintelligible. I’ m going to diarize them a little — so I don’t forget totally and to share a bit of the experience. (And since CA […]

While Steve’s away in San Francisco lecturing scientists about statistics, I thought I’d throw in my announcement of a bold, new frontal assault upon the Forces of Obfuscation: Auditblogs.com

AGU Fall Meeting

I’m leaving tomorrow for San Francisco and will be presenting at the 8 am Union session 11-B on Monday morning. It takes me a long time to prepare short presentations. When I look at them, I wonder why it took so long. Al Gore is heading an AGU session on Thursday. If the convention center […]

More Guliya Mess

The Yang version of Guliya goes back to “AD200” and is dated younger than Thompson et al 2004 (although a younger dating may also be in Thompson et al PNAS 2006). I did a quick comparison of the unarchived visual plot in Thompson et al (Science 1997) and compared it to the Yang version, yielding […]

More on Guliya

I wrote recently on the bizarre spaghetti graph from Guliya – where three inconsistent versions have been used in 2006 articles. I think that I may have a good first step at decoding this mess, as illustrated in the comparison below of the PNAS 2006, Climatic Change 2004 and Yang 2002 versions (used again in […]

Juckes and the David Black Condemnation

I’ve written on several occasions about Juckes’ use of cold water G Bulloides as a supposed temperature proxy (following Moberg’s equally indefensible use of this proxy.) It has come to my attention that a leading specialist, David Black of the University of Akron, had already issued a scathing denunciation of Juckes’ use of G Bulloides […]

Underwater in the Sierra Nevadas

While we’re re-visiting bristlecones and foxtails, here are three interesting online articles, each of which discusses areas in the Sierra Nevada CA, which are now submerged, but where forests grew in the Medieval Warm Period. Many readers of this blog will have read articles about trees being disgorged from receding glaciers and it’s hard not […]

Late 20th Century Limber Pine Growth Decline

Constance Millar, url who wrote an excellent article on the medieval warm period in California, discussed here has written an interesting and timely article (presently in review) on thelate 20th century in the Sierra Nevadas, entitled: Response of high-elevation limber pine (Pinus flexilis) to multi-year droughts and 20th-century warming; Sierra Nevada, California.

Juckes and the Rain in Maine

Juckes stated: MM2003 criticise MBH1998 on many counts, some related to deficiencies in the description of the data used and possible irregularities in the data itself. These issues have been largely resolved in Mann et al. (2004) [the Corrigendum]. Did Juckes carry out any due diligence in order to make the latter statement? Because I’m […]
