In my search for high-resolution ocean sediment records, I stumbled across an interesting 1995 article by Domack et al (Domack of the Larsen Ice Shelf) discussing cores on the west side of the Antarctic Peninsula which were dated over the last 2000 years.
A few days ago, I showed that a trivial variation to the Moberg CVM reconstruction led to a very different medieval-modern relationship. Juckes has reported that the Moberg CVM reconstruction is "99.98% significant" – not quite the most significant in a milllll-yun years, but VERY, VERY significant. I thought it would be interesting to see […]
Lloyd Keigwin’s Sargasso Sea study was done using 1 cm core intervals; the Arabian Sea RC2730 percentage G bulloides was calculated using 2 mm core intervals (although slower sedimentation meant that the time intervals were mitigated somewhat.) see http://www.climateaudit.org/?p=898 . G bulloides percentage is interesting a measure of upwelling, but isn’t a proxy for SST. […]
You have to get up pretty early in the morning to surprise me with one of these millennial proxy series. But even I got a big surprise when I decided to investigate Juckes statement "Concerning the Indigirka data, the key phrase is “they are unpublished data”; and his challenge in 894#13: But seriously, if you […]
Howard Wiseman sends in: I attach a link to Dr. Kerry Emanuel’s recent powerpoint presentation at the Southern New England Weather Conference which focuses on TC activity in the Atlantic. The download is a bit slow, and the presentation is pretty familiar ground. Emanuel’s conclusions are presented with breathless inevitability (surprise). No comments on the […]
Juckes discusses the Divergence Problem as follows: Particular concerns have been raised about … the high latitude Eurasian trees (which have and anomalously low growth anomaly in the late 20th century — Tornetraesk, Fennoscandia, Yamal, Northern Urals in Table 1) No one has ever said that Yamal has an anomalously low growth anomaly in the […]
Keigwin’s Sargasso Sea temperature reconstruction, used in Moberg et al 2005, was de-selected by Juckes in what he represented to be the Moberg CVM composite and in making the Union composite (although he managed to use Tornetrask twice ?!? under different names). Although he de-selected the Sargasso Sea temperature reconstruction, he used Moberg’s Arabian Sea […]
OK, folks. We finally extracted enough information from Martin Juckes to be able to replicate SI Figure 1. I’ll show here how one gets from point A to point B, which will help understand us understand exactly why Juckes did this the way he did. One more time, here is Juckes’ Figure 1 with its […]
In order to reduce noise levels, I am going to act as a type of chairman of the Juckes Omnibus thread. If you wish to comment on that thread, please do so here. If there’s something that I feel should be transferred to the Juckes Omnibus Thread for Juckes to reply to, I’ll do so. […]
Writing a blog is different than writing a referees’ report. I diarize certain points for the blog as I notice them. The function of these notes is to be topical and somewhat interesting. Martin Juckes has been trying to answer some questions and, to avoid strewing comments over multiple threads, I’d like to use this […]
