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 […]
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 […]
A guest post by Nic Lewis Introduction A recent PAGES 2k Consortium paper in Nature,[i] Abram et al., that claims human-induced, greenhouse gas driven warming commenced circa 180 years ago,[ii] has been attracting some attention. The study arrives at its start dates by using a change-point analysis method, SiZer, to assess when the most recent […]
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 […]
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 […]
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 […]
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 […]
A guest post by Nic Lewis Introduction and Summary In a recently published paper (REA16),[1] Mark Richardson et al. claim that recent observation-based energy budget estimates of the Earth’s transient climate response (TCR) are biased substantially low, with the true value some 24% higher. This claim is based purely on simulations by CMIP5 climate […]
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 […]
