CLIMATE SCIENTISTS…PLAGIARISM AND AIRBRUSHING OF FACTS

Trenberth and Lifting Text Verbatim #2

Breaking: Trenberth’s Shame: ‘Deletes original version of presentation and replaces it with an amended version, without a change notice’

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 has obviously been brought to Trenberth and/or AMS’s attention, as they have deleted the original version of Trenberth’s presentation and replaced it with an amended version, without a change notice.

The amended version picks up most of the problems raised in the previous CA post. Here are the points raised in the CA post and Trenberth’s changes:

Trenberth originally stated:

Scientists make mistakes and often make assumptions that limit the validity of their results. They regularly argue with colleagues who arrive at different conclusions. These debates follow the normal procedure of scientific inquiry.

The amended version:

Hasselmann (2010) further notes that scientists make mistakes and often make assumptions that limit the validity of their results. They regularly argue with colleagues who arrive at different conclusions. These debates follow the normal procedure of scientific inquiry.

Trenberth’s originally statement about tactics to use against “deniers”:

It is important that climate scientists learn how to counter the distracting strategies of deniers. Debating them about the science is not an approach that is recommended.

The amended version:

It is important that climate scientists learn how to counter the distracting strategies of deniers (Hasselmann 2010). Debating them about the science is not an approach that is recommended.

Trenberth originally stated:

The main societal motivation of climate scientists is to understand the dynamics of the climate system (both natural and human induced), and to communicate this understanding to the public and governments.

The amended version:

The main societal motivation of climate scientists is to understand the dynamics of the climate system (both natural and human induced), and to communicate this understanding to the public and governments (Hasselmann 2010).

Trenberth did not feel obligated to restate everything that Hasselmann had stated. For example, Trenberth did not repeat Hasselmann’s observation that:

Individually, most climate scientists have the goal of establishing a scientific reputation and, if possible, attaining more public funding for climate research.

Trenberth originally stated:

They [climate scientists] have faith in the scientific method and the efficacy of the established peer-review process in separating verifiable scientific results from baseless assertions.

The amended version:

As Hasselmann (2010) further notes, they have faith in the scientific method and the established peer-review process in separating verifiable scientific results from baseless assertions.

As to the lengthy introductory paragraph which was lifted near-verbatim from Hasselmann, but with no indication that large sections were verbatim: the original Trenberth version was:

Three investigations of the alleged scientific misconduct of the Climate Research Unit at the University of East Anglia — one by the UK House of Commons Science and Technology Committee, a second by the Scientific Assessment Panel of the Royal Society, chaired by Lord Oxburgh, and the latest by the Independent Climate Change E-mails Review, chaired by Sir Muir Russell — have confirmed what climate scientists have never seriously doubted: established scientists depend on their credibility and have no motivation in purposely misleading the public and their colleagues. Moreover, they are unlikely to make false claims that other colleagues can readily show to be incorrect. They are also understandably (but inadvisably) reluctant to share complex data sets with non-experts that they perceive as charlatans (Hasselman 2010)

The amended version is:

As noted by Hasselmann (2010), three investigations of the alleged scientific misconduct of the Climate Research Unit at the University of East Anglia — by the UK House of Commons Science and Technology Committee and by the Lord Oxburgh and Sir Muir Russell reviews — have confirmed that established scientists depend on their credibility and have no motivation in purposely misleading the public and their colleagues. Moreover, they are unlikely to make false claims that other colleagues can readily show to be incorrect. They are also understandably (but inadvisably) reluctant to share complex data sets with non-experts that they perceive as charlatans (Hasselman 2010).

Note here that Trenberth removed the absurd Hasselmann characterization of the Oxburgh inquiry that had passed muster with the editors of Nature Geoscience – that it was the “Scientific Assessment Panel of the Royal Society”. A point also raised in comments in the CA post.

Trenberth did not submit a comment to Climate Audit thanking us for enabling him to mitigate the problem prior to the actual formal presentation of his speech or otherwise thank us at the AMS webpage at which the changes were made.

Even as amended, Trenberth’s use of extended near-quotations without quotation marks must surely still be at the edge of acceptable practice, if not over it.

In appraising whether inadequate citation rises to being academic misconduct, it seems to me that one needs to consider whether there is a claim or implied claim of originality and how such incidents are handled in the field. Trenberth’s speech was not the same thing as a master’s thesis. Trenberth had lifted text, but AMS appears to have decided that the situation could be more or less coopered up by providing more citations to Hasselmann; that the inadequacy of the citations did not entail that the entire speech be withdrawn; or that AMS was obliged to file a complaint against Trenberth for academic misconduct.

It’s also interesting what Trenberth chose to change and not to change. Plagiarism is an issue that is uniquely central to the academic world and Trenberth moved quickly to erase any evidence of plagiarism. The non-academic world would be less concerned about plagiarism and more concerned about Trenberth’s use of the offensive term “denier” and whether Trenberth’s Empire Strikes Back attitudes are a useful contribution to the post-Climategate debate. Although Trenberth was also criticized on these counts, Trenberth made no concessions or changes to this aspect of his speech.
