Picking Cherries in the Gulf of Alaska

The bias arising from ex post selection of sites for regional tree ring chronologies has been a long standing issue at Climate Audit, especially in connection with Briffa’s chronologies for Yamal and Polar Urals (see tag.)  I discussed it most recently in connection with the Central Northwest Territories (CNWT) regional chronology of D’Arrigo et al […]

Cherry-Picking by D’Arrigo

One of the longest standing Climate Audit issues with paleoclimate reconstructions is ex post decisions on inclusion/exclusion of data, of which ex post decisions on inclusion/exclusion of sites/data in “regional [treering] chronologies” is one important family.  This was the issue in the original Yamal controversy, in response to which Briffa stated that they “would never select or manipulate […]

Bob Carter

I was very saddened to learn of the sudden death of Bob Carter ( here here).   He was one of the few people in this field that I regarded as a friend.  He was only a few years older than me and we got along well personally. I will not attempt to comment on […]

Update of Model-Observation Comparisons

The strong El Nino has obviously caused great excitement in the warmist community.  It should also cause any honest skeptic/lukewarmer to re-examine whether observations remain inconsistent with models. In today’s post, I’ll show two comparisons: 1) CMIP5 models (TAS) vs HadCRUT4; 2) CMIP5 models (TLT) vs RSS (UAH is only negligibly different).  For this post, […]

COP21 Emission Projections

In the wake of COP21, I thought that it would be interesting to compare the respective pathways of China and the U.S (and others) based on official data. I still plan to post on this topic, but obtaining official data on the pathways proved much more difficult than I anticipated.  Leading into the COP21 conference […]

Balascio et al and the Baffin Island Inconsistency

There was some publicity this week on a paper by Young et al (Science Advances, 2015), which, according to Gifford Miller , whose work has been frequently discussed at CA (see  tag), had supposedly put the “coup de grace on the Medieval Warm Period”, that had been so long wished for by the Team.   […]

What “Science” is “Telling Us” About Climate Damages to Canada

Just before leaving for Paris, the Canadian government, like many others,  stated that “science” was “telling us” that climate change was “one of the greatest threats of our time”. The scientific evidence is clear: climate change is one of the greatest threats of our time. The Government of Canada recognizes that global temperature increases must be […]

Antarctic Ice Mass Controversies

Like many others, I was interested in the recent controversy arising from findings of Zwally et al 2015 that there had been ice mass gain gain of ~112±61 Gt/year over 1992-2001 and ~82±25 Gt/year over 2003-2008.  Zwally’s findings obviously contradict a widely held contrary belief, expressed, for example, in IPCC AR5’s assertion there was “high confidence” that the […]

Shukla’s Gold

Roger Pielke Jr recently made the remarkable discovery that, in addition to his university salary from George Mason University (reported by Pielke as $250,000), Jagadish Shukla, the leader of the #RICO20, together with his wife, had received a further $500,000 more in 2014 alone from federal climate grants funnelled through a Shukla-controlled “non-profit” (Institute for Global Environment and Security, […]

Reckless Misinformation from Barry Klinger and the RICO 20

The RICO-20 gang of climate academics commenced its supposed campaign against misinformation with false information about skeptic reactions to the Cuccinelli investigation. Barry Klinger, one of Shukla’s hangers-on at George Mason University,  stated: However, I don’t recall climate contrarians coming to the defense of Michael Mann when he was subject to ideologically-based legal harrassment from then-Virginia Attorney General Ken […]
