The Ababneh Thesis

As I mentioned yesterday, Malcolm Hughes and/or the University of Arizona Laboratory for Tree-Ring Research had gone to the trouble of blocking my IP address from accessing their website. Thanks to the help of a couple of CA readers, I was able to circumvent the block. This is the sort of petty behavior that gives […]

A Little Secret

Don’t you think that someone on the Team might have been a little curious as to what bristlecone ring widths have done during the past 25 years? For this, we have the classic excuse of Michael Mann and the Team for not updating bristlecone and proxy records is that it’s not practical within the limited […]

Bürger Comment on Osborn and Briffa 2006

Gerd Bürger published an interesting comment in Science 2006 on cherry-picking in Osborn and Briffa 2006. A few CA readers have noticed the exchange and brought it to my attention. Eduardo Zorita (who I was glad to hear from after our little dust-up at the Nature blog) sent me the info as did Geoff Smith. […]

Hughes on Australian ABC

The Australian Broadcasting Corp. had an interview with Malcolm Hughes on Apr 5 when he once more attempted to blame the messengers for identifying the shortcomings of their own statistical methodology. We eagerly await the Dendro Truth Squad rebutting this “misinformation”.

Wegman's replies to Stupak

I know this is well after the event, but Dr Wegman’s extensive and detailed responses to Rep Stupak‘s written questions are interesting reading. I’m not aware that Steve linked to this document before. Beware though: the file is 10MB in size, so I’d recommend a right click followed by “Save Target as” – otherwise your […]

Salzer and Hughes on Bristlecones

A reader writes in: I think Steve and the other CA readers will be interested in the new article by Matthew Salzer and Malcolm Hughes (of MBH fame) entitled “Bristlecone pine tree rings and volcanic eruptions over the last 5000 yr” in the latest issue of Quaternary Research, “> available for free. I don’t have […]

Underwater in the Sierra Nevadas

While we’re re-visiting bristlecones and foxtails, the 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 […]

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.

Bristlecones and Sagebrush

In MM05 (EE), we reviewed literature on bristlecones because these trees were supposed to be unique radio receivers for world temperature. Obviously the specialist literature stood against this proposition. We cited a number of interesting articles by Mooney in American Midland Naturalist in the 1960s – none of which are considered by Juckes in his […]

Juckes and the Pea under the Thimble (#1)

Juckes has much to say about several MM articles, none of it favorable and little of it accurate. Juckes, like the rest of the Team, seldom quotes our articles – instead, he typically paraphrases what we said, often creating a straw man, which he prefers to deal with. It’s a wearisome task disentangling the many […]
