Arctic Lake Sediments: Reply to JEG

Julien Emile-Geay (JEG) submitted a lengthy comment concluding with the tasteless observation that “Steve’s mental health issues are beyond PAGES’s scope. Perhaps the CA tip jar pay for some therapy?”  – the sort of insult that is far too characteristic of activist climate science.  JEG seems to have been in such a hurry to make this […]

PAGES 2017: Arctic Lake Sediments

Arctic lake sediment series have been an important component of recent multiproxy studies.  These series have been discussed on many occasions at Climate Audit (tag), mostly very critical.  PAGES 2017 (and related Werner et al 2017) made some interesting changes to the Arctic lake sediment inventory of PAGES 2013, which I’ll discuss today.

PAGES2017: New Cherry Pie

Rosanne D’Arrigo once explained to an astounded National Academy of Sciences panel that you had to pick cherries if you wanted to make cherry pie – a practice followed by D’Arrigo and Jacoby who, for their reconstructions, selected tree ring chronologies which went the “right” way and discarded those that went the wrong way – […]

Comey’s Mishandling of Classified Information

Recently, there has been controversy over allegations that former FBI Director Comey leaked classified information, an issue that I mentioned on twitter  a month ago. The recent news-cycle began with a story in The Hill,  leading to a tweet by Trump, followed by a series of sneering “rebuttals” in the media (CNN, Slate, Politico, Vanity Fair). […]

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 […]
