bender has sent in the following interesting graphic showing how drought-caused dieback could bias a tree ring chronology and interfere with interpretation of past records, emphasizing the continued need to keep U-shaped temperature response functions firmly in one’s mind when considering these series. [image being re-sized] (2012 note) For reference, here are some related postings […]
Lee has criticized me for not fully canvassing the supposedly manifold lines of evidence marshalled by the NAS panel against a warmer MWP. So I’ve done a little exercise to summarize the evidence AGAINST the MWP being warmer than mid-20th century, disaggregating what I believe to be the salient information from the spaghetti studies. The […]
Richard Kerr of Science has reported on the House Energy and Commerce Committee hearings. Having lived through the hearings, it’s interesting to see how they get characterized. For example, Kerr says: He [North] said he doesn’t disagree with Wegman’s main finding that a single year or a single decade cannot be shown to be the […]
Roger Pielke has a few threads recently dealing with the House Energy and Commerce Committee hearings – today there’s an op ed by von Storch and Zorita. A few days ago, he posted his own report and then posted up my response letter, both of which have attracted a few comments. I agree with both […]
I’ve set up a new category at right entitled "Archiving" which cross-classifies many of the posts on data archiving and requests. A review from this time last year is here . Since then, I’ve had correspondence with Moberg and Nature, which has resulted in winkling out the other Moberg series (which I’ve yet to process); […]
Post Washington, I was browsing through the turgid prose of Rutherford et al 2005 – which actually uses the original MBH98 data set (PC series and all) for nearly half their analysis, they also consider the mystery Briffa et al 2001 sites, which they also do not reveal. The SI says – contact Tim Osborn, […]
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 […]
New poster bender has written some very thoughtful posts, including some comments on Gaspé which I I’d like to recover from deep in a political thread. The growth pulse in Gaspé cedars seemed very improbable to me as a temperature proxy; bender has some detailed knowledge on the topic.
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.
