Back from Washington. I think that I’ve had enough Washington for a while. It takes me a lot of time to prepare; I don’t begrudge it and it’s useful to try to put what you’re thinking about into short statements, but it still takes time and it’s tiring. It’s a nuisance that Mann couldn’t get […]

News and views on the NAS Panel 2006 chaired by Gerald North
Well, back from Washington. I’m not very good at describing reactions and impressions and touchy-feely stuff like that; I’m more comfortable describing what’s different with the 53rd and 84th series out of 112, but I’ll try.
Here with accompanying editorial by Terence Corcoran here.
Nature has two online articles pertaining to the NAS Panel – one about the NAS Panel primarily relying on the press conference and another mentioning a prospective new NAS investigation into the data access problems left untouched by the past panel. The Nature reporter asked an interesting question at the press conference. I’ve provided a […]
The NAS Panel claimed that MBH98 was the "first systematic" multiproxy study. It wasn’t; it didn’t even claim to be, citing Bradley and Jones 1993 and several other studies of the same vintage as predecessors. Crowley was a peer reviewer for the NAS panel, who presumably relied on him to catch this sort of mis-step. […]
Jean S pointed out the following quote from the NAS Report and suggested that this be discussed: The first systematic, statistically based synthesis of multiple climate proxies was carried out in 1998 by M.E.Mann, R.S.Bradley and M.K. Hughes (Mann et al. 1998); their study focused on temperature for the last 600 years in the Northern […]
When you go through the NAS Panel report closely, it’s amazing how many of our views were adopted – on principal components, statistical skill, statistical methods, bristlecones. I started out trying to make a post showing our views side-by-side with those of of our opponents and those of the NAS Panel, but the post quickly […]
Jean S has written me suggesting that I review the NAS panel claim that Mann was the “first systematic, statistically based synthesis of multiple climate proxies”. This claim is true only in the sense that Al Gore invented the Internet and I will discuss this in the next few days. While I was reviewing the […]
I want to convey one more time that, while I’m going to criticize the NAS report and in some cases I’m going to be pretty hard on it, I think that they are decent, intelligent and knowledgeable people, who’ve tried to do an honest job and who were civil and fair to Ross and I. […]
Now that I’ve caught my breath a little, just for fun, I’m parsing through sections of the NAS report on areas not directly involving the MM-MBH battle. In the press conference, I recall Cuffey placing a lot of emphasis on the "regional" MWP, and that it wasn’t in the Antarctic ice core data (although it […]
