PAGES2K and Nature’s Policy against Self-Plagiarism

Nature’s policies on plagiarism state: Duplicate publication, sometimes called self-plagiarism, occurs when an author reuses substantial parts of his or her own published work without providing the appropriate references. The description of the Australasian network of PAGES2K (coauthors Gergis, Neukom, Phipps and Lorrey) is almost entirely lifted in verbatim or near-verbatim chunks from Gergis et […]

What Happened to Gerald Schatten?

Gerald Schatten of the University of Pittsburgh was one of two corresponding authors (Hwang was the other) of Hwang et al 2005 (Science). As most CA readers know, the Hwang cloning results were fabricated – conduct that, in any field other than climate science, is regarded as more serious than copying boilerplate. For CA posts […]

Team Policy on Acknowledgements

After CA reported Trenberth’s lifting of text from Hasselmann 2010 verbatim or near-verbatim either without citation or, in the one citation, a citation that was inadequate given the lengthy near-verbatim quotation, Trenberth moved quickly to cooper up his presentation against plagiarism allegations by inserting citations to Hasselmann 2010, responding to each of the incidents reported […]

Trenberth and Lifting Text Verbatim #2

On January 14, 2011, I reported here that Trenberth’s AMS presentation had lifted text verbatim or near-verbatim from Hasselmann 2010 with no citation in most cases and, in the one case where Hasselmann 2010 was cited, the citation was insufficient under standard academic practices given the lengthy near-quotation. Trenberth’s original presentation is here. This post […]

Bradley Copies Fritts #2

In my previous post on Fritts and Bradley, I observed that Bradley’s so-called ”seminal” textbook had copied 12 of the first 13 figures in its dendro chapter from Fritts 1976, together with verbatim or near-verbatim caption (with a little more examining, this is now 17 of the first 19 figures in the textbook.) By focusing […]

Bradley Copies Fritts

In an early Deep Climate post about Wegman, DC characterized Bradley 1999, a revision of the 1985 edition of Bradley’s textbook, as “seminal”. In respect to the dendro chapter at least, this is flatly untrue. Bradley copied both graphics and language from Fritts’ 1976 textbook, Tree Rings and Climate. The USA Today article that prompted […]

How Anthony Watts Handled Team Plagiarism

Anthony has an instructive post on how he handled a plagiarism incident involving NOAA. Anthony writes: Readers may recall this post: More dirty pool by NCDC’s Karl, Menne, and Peterson …where I take NCDC to task for not given proper attribution to the surfacestations.org and volunteer Russ Steele for use of a photo on the […]


As readers know, Raymond Bradley’s allegation that “text was just lifted verbatim from my book and placed in the Wegman Report” has been widely publicized following Bradley’s interview with USA today. The allegation pertains to Wegman’s boilerplate section (2.1) describing proxies, a section in which neither MBH98-99 nor MM2003, 2005abcd are mentioned, and on which […]

Say My Name – February Rerun

Science has published a Correction and Clarification to Kaufman et al (2009), see here. Since they only needed to correct four out of 23 proxies, there is no need to name those who pointed out errors. 😉 There is a small improvement over the draft version though; congratulations Hu! We thank H. McCulloch and others […]

Steig Professes Ignorance

On Feb. 26, I wrote a post on CA, “Steig 2009’s Non-Correction for Serial Correlation”, commenting on the Jan. 22 letter in Nature by Eric Steig et al. On Feb. 28, I sent Steig and his 5 co-authors an e-mail alerting them to my post and its content. On Aug. 6, Steig and co-authors published […]
