Centenary of the End of the Battle of the Somme

November 18 marks the centenary of the end of the Battle of the Somme, an event that passed essentially unnoticed, though it was a seminal event in the development of modern Canada. Its carnage was over 1.1 million casualties from a combined population (both sides) of about 170 million. (For a scale, there have been approximately […]

The Destruction of Huma Abedin’s Emails on the Clinton Server and their Surprise Recovery

Despite extraordinarily intense coverage of all aspects of Hillary Clinton’s emails, all commentary to date (to my knowledge), even the underlying FBI Report, has paid little to no attention to the destruction of Huma Abedin’s emails, also stored on the Clinton server.  Further, even with the greatly increased interest in Huma’s emails arising from the discoveries […]

Re-examining Cook’s Mt Read (Tasmania) Chronology

In today’s post, I’m going to re-examine (or more accurately, examine de novo) Ed Cook’s Mt Read (Tasmania) chronology, a chronology recently used in Gergis et al 2016, Esper et al 2016, as well as numerous multiproxy reconstructions over the past 20 years. Gergis et al 2016  said that they used freshly-calculated “signal-free” RCS chronologies […]

Esper et al 2016 and the Oroko Swamp

Jan Esper, prominent in early Climate Audit posts as an adamant serial non-archiver, has joined with 17 other tree ring specialists, to publish “Ranking of tree-ring based temperature reconstructions of the past millennium” (pdf). This assesses 39 long tree ring temperature reconstructions. The assessment is accompanied by an archive containing 39 reconstruction versions, together with the underlying measurement […]

Gergis and Law Dome

In today’s post, I’m going to examine Gergis’ dubious screening out of the Law Dome d18O series, a series that has been of long-standing interest at Climate Audit (tag). Gergis et al 2016 stated that they screened proxies according to significance of the correlation to local gridcell temperature. Law Dome d18O not only had a significant […]

Joelle Gergis, Data Torturer

In 2012, the then much ballyhoo-ed Australian temperature reconstruction of Gergis et al 2012 mysteriously disappeared from Journal of Climate after being criticized at Climate Audit. Now, more than four years later, a successor article has finally been published. Gergis says that the only problem with the original article was a “typo” in a single […]

Deflategate: Controversy is due to Scientist Error

I’ve submitted an article entitled “New Light on Deflategate: Critical Technical Errors” pdf to Journal of Sports Analytics. It identifies and analyzes a previously unnoticed scientific error in the technical analysis included in the Wells Report on Deflategate. The article shows precisely how the “unexplained” deflation occurred prior to Anderson’s measurement and disproves the possibility of post-measurement […]

Schmidt’s Histogram Diagram Doesn’t Refute Christy

In my most recent post,  I discussed yet another incident in the long running dispute about the inconsistency between models and observations in the tropical troposphere – Gavin Schmidt’s twitter mugging of John Christy and Judy Curry.   Included in Schmidt’s exchange with Curry was a diagram with a histogram of model runs. In today’s […]

Gavin Schmidt and Reference Period “Trickery”

In the past few weeks, I’ve been re-examining the long-standing dispute over the discrepancy between models and observations in the tropical troposphere.  My interest was prompted in part by Gavin Schmidt’s recent attack on a graphic used by John Christy in numerous presentations (see recent discussion here by Judy Curry).   Schmidt made the sort of offensive allegations that […]
