But Mike, Martin Durkin is (or at least used to be) a self-proclaimed Marxist.
From the Climategate 2.0 collection, hokey stick inventor is bent out of shape by “The Great Global Warming Swindle”:
as I suspected, this is being done by a right wing hack, his name is Martin Durkin. He appears to be the British version of our John Stossel.
Monbiot’s all over him:

anyone have contact info for Monbiot?

Dear Professor Mann,
Thank-you for your note. As you know, better than anyone, your paper,
and the subsequent work in this area, is of enormous significance. The
‘hockey stick’ is one of the defining images of the whole theory of man
made global warming. Much rests on the assertion that the current
period is the warmest in a thousand years – it suggests, as you know,
that the current warming is something we should be concerned about.
The accuracy, or otherwise, of the hockey stick is therefore of immense
public interest. As you know, your study ran counter to received opinion
on climate history up to that point. It is not unreasonable to ask
whether it was right.
I will do my best to study the references you have sent. But we are
unable, in a film, to reproduce emails. However, we can repeat our
request for a television interview with you, so that you can respond in
person to the critique of McIntyre and McKitrick, Weman and others.
Yours sincerely,
Martin Durkin
Director

Dear Ms. Arman,
Unfortunately I will not be available for an interview for your
documentary. However, if you are interested in the true current state of
affairs I suggest you contact scientists such as Caspar Ammann of NCAR
and David Ritson of Stanford University, who have independently
investigated the claims of our critics and shown them to be either
incorrect, inconsequential, or both. You can find much relevant
discussion and links to key peer-reviewed recent studies on the site
“RealClimate.org”.
I would like to bring three main points to your attention:
1. The studies of Mann, Bradley and Hughes (1998, 1999) are more than a
decade old, and a decade of more recent work by a wide range of
researchers both supplants them and validates the key conclusions.
Quoting from a report by the U.S. National Academy of Sciences published
last summer,
” The basic conclusion of Mann et al. (1998, 1999) was that the late
20th century warmth in the Northern Hemisphere was unprecedented during
at least the last 1,000 years. This conclusion has subsequently been
supported by an array of evidence that includes the additional
large-scale surface temperature reconstructions and documentation of the
spatial coherence of recent warming described above (Cook et al. 2004,
Moberg et al. 2005, Rutherford et al. 2005, D’Arrigo et al. 2006, Osborn
and Briffa 2006, Wahl and Ammann in press), and also the pronounced
changes in a variety of local proxy indicators described in previous
chapters (e.g., Thompson et al. in press). Based on the analyses
presented in the original papers by Mann et al. and this newer
supporting evidence, the committee finds it plausible that the Northern
Hemisphere was warmer during the last few decades of the 20th century
than during any comparable period over the preceding millennium. ”
More information on the National Academy report is available here:
http://www.realclimate.org/index.php/archives/2006/06/national-academies
-synthesis-report/
2. The specific criticisms of McIntyre and McKitrick (2005) have been
invalidated by at least 5 different peer-reviewed studies (only 1 of
which I was associated with).
– Wahl and Ammann (in press) demonstrate that (a) the precise
statistical conventions used in our original work have almost no
influence on the end result, which is quite robust and easily replicated
and that (b)each of their primary claims are seen to have been based on
a number of inappropriate and erroneous procedures on their part. See:
e.g. the discussion here:
http://www.realclimate.org/index.php/archives/2005/05/new-analysis-repro
duces-graph-of-late-20th-century-temperature-rise/
– Two additional papers by Von Storch et al and Huybers take issue with
the McIntyre and McKitrick claims, discussed here:
http://www.realclimate.org/index.php/archives/2005/10/hockey-sticks-roun
d-27/
– This paper published by my collaborators and me: Rutherford, S., Mann,
M.E., Osborn, T.J., Bradley, R.S., Briffa, K.R., Hughes, M.K., Jones,
P.D., Proxy-based Northern Hemisphere Surface Temperature
Reconstructions: Sensitivity to Methodology, Predictor Network, Target
Season and Target Domain, Journal of Climate, 18, 2308-2329, 2005.
Discussed here: http://www.realclimate.org/index.php?p=10 and the final
published version is available here at:
Click to access RuthetalJClimate05.pdf
The basic conclusion from these additional studies are that the claims
made by M&M (2003) are either incorrect, or do not have any consequences
for the conclusions of MBH98. A figure from Wahl and Amman demonstrates
the
non-impact of any of the legitimate issues that they may have raised
quite clearly:
http://www.realclimate.org/images/WA_RC_Figure1.jpg
3. The Wegman report was not the result of an impartial scientific
inquiry, but was instead commissioned as part of a partisan
investigation that was condemned by leading scientific organizations
around the world, see e.g. the materials available here:
http://branch.ltrr.arizona.edu/
http://www.geo.umass.edu/climate/bartonletter.html
Neither Wegman nor anyone else associated with that report contacted me
at any time. Nor did he investigate what impact changing statistical
conventions had on the actual climate reconstructions. As was pointed
out long ago (and emphasized by several scientists in congressional
hearings last summer), such changes have an entirely inconsequential
impact on the reconstruction itself. Wegman has also ignored inquiries
from other scientists such as emeritus Stanford University Physics
Professor David Ritson who has requested information about the
calculations within the report. To my knowledge, Wegman has ignored a
congressional inquiry from last year requesting such information.

ckeystick-hearings/
http://www.realclimate.org/index.php/archives/2006/07/the-missing-pieceat-
the-wegman-hearing/
Finally, I would point out that the evidence for human-caused global
warming is based on many independent lines of evidence, including the
fundamental physics of radiative transfer, various different types of
climate observations and sophisticated comparisons of model-predicted
changes with what has been observed. As mentioned above, our early
studies were just one of many indicating that recent climate changes are
anomalous in a long-term context, and all of these studies constitute
just one of multiple lines of evidence implicating human activity for
significant changes that have already been observed in the climate.
From the title of this documentary, I fear that the producers do not
have a proper appreciation of what science actually has to say about the
issues addressed by the documentary.
Sincerely,
Michael E. Mann
