Richard Alley has been a prominent figure in climate change debate. Again we were told to expect a fire-and-brimstone presentation with warnings about tipping canoes. His presentation was lively, but, like Schrag, Alley expressed great caution about what could legitimately be expected from paleoclimate studies and made some very interesting remarks about the disconnect between […]
Yes, Minister was a wonderfully funny British comedy of a generation ago, (some info here and here or google yes minister humphrey) which featured Sir Humphrey Appleby as a senior civil servant (deputy minister) "managing" the Minister, his nominal boss, but who was always outwitted by Sir Humphrey. Each episode would start off with the […]
I know that many of you want to hear our take on Mann (and on ourselves). I’ll get to that. I want to set down some notes on the other speakers while my notes are relatively fresh in my mind; my notes on the morning session are not great, but I’ll give a gist of […]
Back from Washington and quite tired. Lots to report, but don’t have much time today. Anybody hoping that we would be sent home with our tails between our legs will be disappointed. I don’t think that I’ll say much about the panel, at least for now, but I will talk about some of the presentations. […]
Off to Washington this afternoon. I’ve been contacted in advance by one representative of the media who’s going to be covering the entire event. If anyone wishes to contact me, email me in the next few hours and I’ll give a cell #. I’ll post up our presentation in a few days. I appreciate the […]
I checked the Lauritzen series sent to me a few days ago by Moberg and found more discrepancies. I originally observed a discrepancy between the figure in the source article and the figure shown in the SI to Moberg et al [2005] as shown below. The graphic in Nature ended in the 1930s, while the […]
Briffa et al [Holocene 2002] describes a procedure for estimating confidence intervals that is applied in Jones et al [2001] as well. Bloomfield (pers. comm.) is cited as a source, although it’s inconceivable that he was aware of the Briffa truncation. I don’t see how you can claim precise confidence intervals when your post-1960 completely […]
Here’s the appearance schedule. There are 10 presentations. Hughes and Mann each get a separate speaking slot while Ross and I are combined into one. It’s a pretty blue-chip set of speakers. We get the last speaking spot on Thursday at the end of a long day, just before cocktails. Hughes and Mann get to […]
People have been wondering why there is such difference between Polar Urals versions. In many cases, the archived Osborn and Briffa [2006] version (smoothed) is consistent with the emailed Esper et al [2002] version – but not always. It’s always worthwhile examining differences and here are a few.
I’ve got to get back to the NAS presentation and this will be my last post on Polar Urals and Yamal for a while, but it is all quite delicious. Anyway, here is a spaghetti graph of 3 Polar Urals results – including the results from Esper et al [2002] just disclosed by Science, all […]
