PAGES2K: North American Tree Ring Proxies

The PAGES (2017) North American network consists entirely of tree rings. Climate Audit readers will recall the unique role of North American stripbark bristlecone chronologies in Mann et al 1998 and Mann et al 2008 (and in the majority of IPCC multiproxy reconstructions).  In today’s post, I’ll parse the PAGES2K North American tree ring networks […]

PAGES2K (2017) – South America Revisited

The most recent large-scale compilation of proxy records over the past two millennia is PAGES (2017).  They made a concerted effort to archive data (to the credit of Julien Emile-Geay), archiving 692 series, but they perpetuated most other sins within the field.  Rather than abjuring ex post screening, it carried ex post screening to extremes never […]

A Russian Spearphishing Domain Is Now Hosted in New York City

Central to the Mueller indictment is attribution to Russia of a spearphishing campaign from domains then located in Romania. It is therefore more than a little surprising that one of these spearphishing domains is not only still in operation in May 2018, but hosted in New York City.

WHO on Douma

Jordan Peterson, a fellow Torontonian who is obviously not shy about challenging authority, recently cited the World Health Organization (WHO) on Douma chemical attacks as follows: WHO says: “Bombs were dropped at two locations in Douma. Within hours, more than 500 people were exhibiting symptoms consistent with suffocation by poison gas.” On such a controversial issue, it […]

Douma Videos and Photos

In this post, I will provide a timeline of original appearances of videos and photos of the Douma chemical incident. There were two locations for these videos: (1) the emergency ward of the Douma hospital; (2) a small apartment building about 10 blocks from the hospital, where dead bodies were found on two floors and […]

The impact of recent forcing and ocean heat uptake data on estimates of climate sensitivity

A guest post by Nic Lewis Judith Curry and I have now updated the LC15 paper with a new paper that has been published in the Journal of Climate There has been considerable scientific investigation of the magnitude of the warming of Earth’s climate by changes in atmospheric carbon dioxide (CO2) concentration. Two standard metrics […]

Emergent constraints on climate sensitivity in global climate models, Part 3

The two strongest potentially credible constraints, and conclusions A guest post by Nic Lewis In Part 1 of this article the nature and validity of emergent constraints[1] on equilibrium climate sensitivity (ECS) in GCMs were discussed, drawing mainly on the analysis and assessment of 19 such constraints in Caldwell et al. (2018),[2] who concluded that […]

Attribution of 2015-6 Phishing to APT28

In two influential articles in June 2016, immediately following the Crowdstrike announcement, SecureWorks (June 16 here and June 26 here) purported to connect the DNC hack to a 2015-6 phishing campaign which they attributed to APT28.  SecureWorks identified two malicious domains in their article. In today’s article, I’ll show that infrastructure from one domain are connected […]

Emergent constraints on climate sensitivity in global climate models, Part 2

The four constraints that Caldwell assessed as credible A guest post by Nic Lewis In Part 1 of this article the nature and validity of emergent constraints[i] on equilibrium climate sensitivity (ECS) in GCMs were discussed, drawing mainly on the analysis and assessment of 19 such constraints in Caldwell et al (2018; henceforth Caldwell),[ii] who […]

DNC Hack due to Gmail Phishing??

In two influential articles in June 2016 (June 16 here and June 26 here), SecureWorks purported to link the then recently revealed DNC hack to Russia via a gmail phishing campaign which they had been monitoring since 2015 and which they attributed to APT28 (Fancy Bear). They had observed multiple phishing targets at hillaryclinton.com, dnc.org […]
