John Christy writes in reply to my email, occasioned by Connolley’s remark that Wentz and Mears had been forced to reverse engineer his code: Steve: We gave RSS the part of the code that was still a source of confusion (a correction for diurnal drift for the LT product). In addition, we provided intermediate adjustment […]
Jim Erlandson writes in with the following reference. If you follow through to the link at Northwesterm, you will see the cases and the judgements. Interesting issues abound. Take a look at the Amicus Brief by various scientists, including the omnipresent J.M. Wallace of our NAS Panel. From today’s Wall Street Journal Law Blog: Greenhouse […]
Lots of interesting things to find when you turn over the rocks of Hansen et al 2006. These are comments on work in progress, but, to say the least, there appear to be some curious decisions and methodologies.
The new Santer et al. paper, Forced and unforced ocean temperature changes in Atlantic and Pacific tropical cyclogenesis regions, purports to show that sea surface temperature (SST) changes in the Pacific Cyclogenesis Region (PCR) and the Atlantic Cyclogenesis Region are caused by anthopogenic global warming (AGW). They claim to do this by showing that models […]
Mg/Ca proxies measure the temperature of calcification of G. ruber, which is not necessarily the same as surface temperature. Dahl et al state G. ruber is present year–round at Site 723B, but experiences blooms during both monsoon seasons and calcifies above 80 m water depth (14–16)…. In accordance with the seasonality of G. ruber in […]
Weaver says the next generation of his climate model will address the influence of climate on human evolution. I guess we can expect headlines saying that scientists University of Victoria have shown that global warming, if left unchecked, will lead to the development of a third eye by the year 2075.
I’ve had a chance to examine Hansen’s argument a little more closely. Structurally it’s a typical splicing argument that we’re familiar with – proxies up to a certain point and then instrumental temperature. In the case of MBH, they use proxies up to 1980 and then compare that to instrumental records. We’re all familiar with […]
We’re going to be hearing more about this – see press release here for example. I’ll add to this headnotes, but, for now, I’ll post up some URLs that some of you may find handy. The underlying article by Hansen et al is at PNAS here. They thank Ralph Cicerone for his review comments. The […]
The U.S. CCSP report on temperature trends includes the following remarkable recommendations on audit trails: The independent development of data sets and analyses by several independent scientists or teams will serve to quantify structural uncertainty and to provide objective corroboration of the results. In order to encourage further independent scrutiny, data sets and their full […]
Get ready for a new round of satellite disputes. Spencer and Christy have version 6.0 out in draft form as of Sept 9, 2006. Here’s a plot of the data from the website . The SH result is particularly intriguing – now showing virtually no change. In the recent U.S. CCSP report, as pointed out […]
