Global warming “hockey stick” is turning into a baseball bat

@Steve McIntyre

From Fig. 4 above:

it’s quite obvious that in 2009 and again in 2011, you shamelessly plagiarised Briffa 2013

Easily the worst sin in the academic book, run a close second only by disrupting the space-time continuum in order to perform the plagiarism)

======================================================

Steve McIntyre’s objections to the Yamal tree (“the most important tree in the world”) in the global warming hockey stick are being vindicated as the new version of the data series resembles a baseball bat much more than a hockey stick.

The McIntyre – The Bane of Climate Dogma and Mighty Slayer of Hockey Sticks

March 17, 2013

Steve McIntyre is

known in particular for his statistical critique, with economist Ross McKitrick, of the controversial hockey stick graph, which shows a sharp, and arguably unprecedented, increase in late 20th century global temperature.

He is at his sleuthing best again and Science will soon have to retract this new “hockey stick” paper

A Reconstruction of Regional and Global Temperature for the Past 11,300 Years, by Shaun A. Marcott, Jeremy D. Shakun, Peter U. Clark and Alan C. Mix, Science 8 March 2013: Vol. 339 no. 6124 pp. 1198-1201 DOI: 10.1126/science.1228026

This paper is apparently based on Marcott’s PhD thesis but the thesis contains no hockey stick!

By the time the paper was published a hockey stick had appeared.  In the most generous interpretation  the paper was “modified” to fit in with global warming dogma before being published in Science. A less generous – but more likely –  interpretation is that this is just fraud instigated probably by the global warming pundits who were the reviewers of the Science paper.

McIntyre’s latest post is a breathtaking indictment of the paper:

Marcott, Shakun, Clark and Mix did not use the published dates for ocean cores, instead substituting their own dates. The validity of Marcott-Shakun re-dating will be discussed below, but first, to show that the re-dating “matters” (TM-climate science), here is a graph showing reconstructions using alkenones (31 of 73 proxies) in Marcott style, comparing the results with published dates (red) to results with Marcott-Shakun dates (black). As you see, there is a persistent decline in the alkenone reconstruction in the 20th century using published dates, but a 20th century increase using Marcott-Shakun dates. (It is taking all my will power not to make an obvious comment at this point.)

The media went bonkers in reporting the Marcott paper  and this diagram will now go down in infamy:

This scandal is causing much attention ( here and here) but there is a deafening silence from the authors, from Science and from the – no doubt – anonymous reviewers.

I cannot draw but I have a clear image of a lone McIntyre battling against the Hockey Sticks. Perhaps a Josh can do justice to the image in my head.

Another warming hockey stick is withdrawn/”put-on-hold” for bad data

June 9, 2012

One would think that after Climategate, climate scientists would be a little more careful with their “trickery”.

When a supposedly peer reviewed paper in the American Meteorological Society Journal  is withdrawn / “put on hold” after publication when the on-line community (Jean S / Steve McIntyre) find the authors to have cherry picked and improperly “massaged their data, it says 2 things:

  1. that the peer review process at the AMS is either incompetent or corrupt (in that it is especially friendly to papers propounding the global warming orthodoxy), and
  2. that the “tricks” revealed by Climategate are still being actively used by so-called climate scientists  to support their beliefs

That one of the authors – probably responsible for this cock-up – a Joelle Gergis from the University of Melbourne, is more an “activist” than a “scientist” does not help matters . Going through the abstracts of her list of publications suggests that she often decides on her conclusions first and then selects data and writes her papers to fit the conclusions. Cherry picking data is bad enough but when it is done because of confirmation bias it is perhaps the most insidious form of scientific misconduct there is.

Interestingly

joellegergis.wordpress.com is no longer available.

The authors have deleted this blog.

The AMS Journal “peers” who reviewed this paper don’t come out of this very well either. But of course they will receive no strictures for a job done badly.

When plagiarism is not plagiarism : part 2

January 17, 2011

Plagiarism has never been considered misconduct in the political arena. And it would seem it is not considered misconduct when purported science is used in a political or religious cause.

I posted earlier about how plagiarism is not plagiarism in the eyes of a journal editor when it is done in his own journal.

https://ktwop.wordpress.com/2010/12/31/ethics-of-journals-when-plagiarism-is-not-plagiarism/

Steve McIntyre reports on another case where science is subordinated to political and religious beliefs.

http://climateaudit.org/2011/01/16/trenberth-and-lifting-text-verbatim-2/

Apparently plagiarism is not plagiarism when carried out by Kevin Trenberth in support of his religious beliefs. But the actions reported here to hastily introduce attributions wherever plagiarism had been detected, suggest that Trenberth realises that if his scientific misconduct is shown then his religious positions are undermined and discredited.
