News and views on the NAS Panel 2006 chaired by Gerald North

The NAS Panel and Polar Urals

Now that we know the abysmally low replication of the modern portion of Briffa’s Yamal chronology (something previously unknown to specialists), I’ve been backtracking through some earlier documents to see how this may have impacted past studies. We’ve talked previously about how Briffa refused to provide measurement data to D’Arrigo et al 2006, resulting in […]

NAS Report on Data and Methods Disclosure

Jeff Id on the Air Vent has written a post pointing out the recent publication online of a report by the Committee on Ensuring the Utility and Integrity of Research Data in a Digital Age from the National Academy of Sciences: Ensuring the Integrity, Accessibility, and Stewardship of Research Data in the Digital Age. I […]

The NAS Panel on Data Availability

One of the by-products of data stonewalling by Team climate scientists was the appointment of a NAS panel entitled “Ensuring the Utility and Integrity of Research Data in a Digital Age”, noted up a couple of years ago at CA here. According to its webpage, the panel’s last hearing was in late 2007. The webpage […]

The Wegman and North Reports for Newbies

In recent discussion of the Weblog 2007 Awards, several commenters at other blogs have argued that our criticisms of the Mannian parlor tricks have been “thoroughly refuted and discarded by climatologists, published in a credible journal”; that “other professionals in the field who also have “looked in great detail at the problem at hand” and […]

The Mysterious Taylor Dome Borehole

Last year, one of the first things that puzzled me about the NAS panel report was the basis for their conclusion that there was no MWP in Antarctica. At the press conference, at about minute 60, North said: there is evidence of warmth in the record in the MWP. But as Bradley and Diaz a […]

NAS: Assuring the Integrity of Research Data

per inquired recently about obtaining a copy of Gerry North’s presentation to the newly minted NAS Panel on Assuring the Integrity of Research Data, which held its first hearings last week. Gerry North was appropriately the first speaker, as the new panel was occasioned by problems left unanswered by the North panel, although its terms […]

An Esper Divergence Problem

The NAS Panel used Esper et al 2002 as a comfort series in their spaghetti graph, but did not perform any due diligence on it. As some of you may recall, I’ve had prolonged correspondence with Science, after being stonewalled by Esper, and, as a result of that, have obtained versions of the chronologies used […]

Reply from Cicerone of NAS

On Aug 12, I wrote to Ralph Cicerone, President of NAS, asking him to request unarchived data from various authors relied upon by the NAS Panel as follows: I enjoyed the opportunity to chat with you during the most recent hearings of the House Energy and Commerce Committee. As I have previously written to you, […]

North and NAS on Bristlecones

BTW, I thought that the Chronicle colloquy was pretty interesting. I don’t usually get to ask people questions directly, so I appreciated that the Chronicle allowed questions through without Gavin Schmidt/realclimate censoring. Now that I think of it, the only other question that I’ve been able to ask a climate scientist directly was to Caspar […]

Pat Frank on North's Seminar

Here is Pat Frank’s post on North’s seminar. You should also look at North’s answers in the Chronicle Q&A session yesterday. North has a slide in his presentation entitled “Enter the Amateurs”. If one associates professionalism with care and due diligence, one wonders whether he has placed this particular cue at the right location in […]
