I recommend that CA readers visit UC’s blog for some interesting discussion. (BTW UC visited Toronto recently and we had a nice dinner.) UC posted the following interesting figure on Unthreaded as follows: BTW, got interesting result when I replaced Temperature PCs with solar in MBH98 algorithm. Similar RE values as in the original, and […]
David Black and associates have just (Oct 2007) published a new paper showing a reconstruction of SST from Cariaco sediments using Mg-Ca for the period 1221-1990 (thanks to Eduardo Zorita for alerting me to the study.) In this case, I am happily able to report that the relevant data was archived at WDCP contemporary with […]
With October nearly done circling the drain, I figure it is about time to bring out the broom : Northern Hemisphere tropical cyclone activity is at historically low levels . In fact, September 2007 suffered the lowest ACE since 1977 ! Even scarier, so far 2006 and 2007 have the lowest October ACE since 1976 […]
In our recent discussion of the Arabian Sea G Bulloides series, I noticed a remarkable increase in the coarse fraction percentage in the top 1.3 cm of the critical RC2730 core. Willis has also commented on this. In core 2730, there is a correlation of 0.91 between the fraction of coarse particles and the percentage […]
Gerry North will be back in Boulder on Nov 2, 2007 delivering a lecture at CIRES at 4 pm on climate over the past 1000 years. The announcement says A variety of evidence points to a gradual cooling of the planet from about 1000 AD to a few hundred years ago when it bottomed out. […]
Max Berkelhammer, a student of Lowell Stott ( a prominent and excellent researcher on ocean sediments) has been carrying out research on dO18 content of bristlecones in the White Mountains. His website shows that he has an article on this research that has been accepted for G3 and CA readers should pay attention to this […]
I just learned (too late) about an interesting workshop sponsored by the American Statistical Association this weekend in Boulder. The announcement last summer stated: The American Statistical Association (ASA), the nation’s preeminent professional statistical society, today announced it will sponsor a two-day climate change workshop featuring 2025 leading statisticians and atmospheric scientists. The event, sponsored […]
One of the reasons why scientists have been so quick to use tree ring information despite all the problems is that, for the most part, there is excellent dating control on tree ring chronologies, something which can be problematic in other proxies. Today I want to document some notes on dating the Arabian Sea G […]
realclimate apologist Eli Rabett explained at Tamino why real climate scientists haven’t updated the bristlecones: You hike out to the ass end of nowhere, take a core (from the right tree, and bring it back. Now you have to analyze it. . . . . . Sure sounds like a lot of work for a […]
On an earlier occasion, I observed that one of the key Moberg series (and now an essential Juckes series) was the Arabian Sea percentage G. Bulloides series. At the time, I observed that G. Bulloides was an indicator of cold water. In the Arabian Sea, the surface water offshore Oman (where the core used in […]
