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 […]

Abram et al 2014 and the Southern Annular Mode

In today’s post, I will look at a new Naturemag climate reconstruction claiming unprecedentedness (h/t Bishop Hill): “Evolution of the Southern Annular Mode during the past millennium” (Abram et al Nature 2014, pdf). Unfortunately, it is marred by precisely the same sort of data mining and spurious multivariate methodology that has been repeatedly identified in […]

Ship of Fools

Like many others, I’ve been intrigued by the misadventures of the Ship of Fools. Dozens of tourist vessels visit the Antarctic without becoming trapped by ice. So it’s entirely valid to inquire into why the one tourist vessel led by a “climate scientist” became trapped by ice. The leader of the expedition, Chris Turney (also […]

Connolley co-author: “Unfortunately we have deleted all the NetCDF files…”

Recently, I made a request to Thomas Bracegirdle, junior partner of Connolley and Bracegirdle, for the model data used in two recent articles: Bracegirdle and Connolley (GRL 2007) about 20th century Antarctic models; and Bracegirdle, Connolley and Turner (JGR 2008) about 21st century Antarctic models. William Connolley is well known in the blogosphere, especially for […]

Steig’s “Corrections”

Roman M has already done one post on the impact of the Harry error. Ryan O has also done so [see comment here]. As has Steig. I show below some graphics that I’ve just done on AWS recon trends. At Steig’s website, he now states: awsreconcorrected.txt is a correction to the above file, using corrected […]


Moving right along since the problem with Harry was identified on Super Bowl Sunday, BAS reports: This is a list of corrections that have been made to the AWS data tables and a link to the table before the corrections were applied, any suspected errors should be reported to Steve Colwell (2/2/09)The AWS data for […]

Steig versus Hansen

In Dec 2004, Steig and Schmidt wrote The Antarctic Peninsula, site of the now-defunct Larsen-B ice shelf, has warmed substantially. On the other hand, the few stations on the continent and in the interior appear to have cooled slightly (Doran et al, 2002; GISTEMP). At first glance this seems to contradict the idea of “global” […]

Antarctic RegEM

Image by mark van de wouw via Flickr For discussion of new study. by Steig (Mann) et al 2009. Data: Data sets used in this study include the READER and AWS data from the British Antarctic Survey. SI Tables 1 and 2 provide listings. They leave out station identifications (a practice that “peer” reviewers, even […]
