I’m actually looking into the WDCP updates page more regularly now to see if any new information has been archived. Five more Jacoby data sets have been archived in the past week: one from the Yukon, 4 from Mongolia. There are still far more that have not been archived than have been archived, but that […]
On Thursday, April 20, the BBC has a show on Overselling Climate Change. BBC radio attended the NAS Panel and taped lengthy portions of it, as well as interviewing me, Hughes and others. It will be interesting to get their take on it. The title of the show seems pretty unusual in a BBC context. […]
Demonstrating that scientific misconduct can happen anywhere, and not simply in one study, the case of Dr Ranjit Kumar Chandra is a case in point. St. John’s, Nfld. [Newfoundland], may seem like an unlikely place for scientific scandal to brew, but in hindsight it appears, perhaps, the perfect place. For almost three decades, Memorial University […]
Last summer, after Paul Thacker published a critical article about me in Environmental Science & Technology (also try here), I contacted three of the people prominently quoted in the article – Mahlman, Trenberth and Famiglietti – to obtain confirmation of what they said. As you will see below, their responses are extraordinarily lame. None of […]
During the past 20 years, Jacoby and D’Arrigo had obtained over 45 RW series and at least 35 MXD series in North America. To the end of 2005, despite receiivng millions in grants, he had only archived a couple of North American RW series and no North American MXD series. I discussed this before here, […]
Paul Thacker, who wrote about me very unfavorably in Environmental Science & Technology last August, has written another unfavorable story for the SE Journal here. Thacker thinks that it’s a big deal that we were covered by the Wall Street Journal and that this is an anomaly pointing to bias. He ignores the fact that, […]
I meant to write about this particular smoking gun some time ago, but I didn’t want to take away attention from Steve’s travails with the NAS Panel and with Geophysical Research Letters. Willis Eschenbach did the actual replication so really it’s his story. If you cast your minds back to last year, a modelling study[1] […]
A nice favorable mention today in an article by Bob Carter in the Daily Telegraph today. Bob Carter is an Australian geologist, who has carried out extremely interesting analyses of clnmate variability over the past 3.6 million years. I showed one of his graphs here -scroll to the bottom. This is not an entirely unbiased […]
I mentioned a couple of days ago that Schweingruber et al [1993] seems to arrive at opposite conclusions to Jacoby and D’Arrigo [1989] as to whether anomalous post-1950 ring widths occur (let alone whether that is due to CO2 fertilization or temperature.) It was interesting to compare Schweingruber-Kienast results at Niwot Ridge. It turns out […]
Reviewing the bidding: at Niwot Ridge, a short drive from UCAR world headquarters, we have disparate chronologies from Graybill and Woodhouse for limber pine at similar elevations (with Graybill’s chronology also discrepant from nearby chronologies from Kienast and Schweingruber for very close PCEN series). Despite the disparate appearances, the correlation between the Graybill and Woodhouse […]

BBC Radio: Overselling Climate Change
