Dear all,
This translation from my colleague Gavin Schmidt,
Global Warming: Climatologists respond to the American right.
The scientific consensus against the ideologues: The heat is on!
Thirty eminent (anglo-saxon) scientists specialising in climate
change and the greenhouse effect have just re-affirmed in an
article in EOS that the anthropogenic contribution to global
warming is stronger than a simple hypothesis. The article is a
response to a a series of publications that the Bush administration
are relying on to reject the terms of the Kyoto Protocol.
Among the authors in the EOS article, we find Michael Mann,
geophysicist from UVa. His research has evaluated the impact of
human activity on planetary climate. He has notably put forward
evidence of highly abnormal temperature rises in the 20th
Century. His studies, published in some of the most prestigious
journals, have contributed to what the National Academy of Science
and AGU recognised in 1998, as anthorpogenic global warming.
Don't touch my car!
Despite the growing number of studies that indicate that the
current levels of GHG emissions are destabilising the global
climate, the American government still refuses to ratify the Kyoto
Protocol. Apart from ideological arguments concenring the 'sacred
character of the American way of life', the Bush administration
argues against the scientific case presented in the IPCC reports.
The administration particularly relies on the work of two
astrophysicists, Willie Soon and Sallie Baliunas. These two have
denied the reality of the warming during the 20th Century in two
different articles. These studies were little noticed in the
scientific world, but were nevertheless largely financed and
publicised by the "think tanks" on the American right. The intense
lobbying that led to the rejection of Kyoto was accompanied by the
creation of a series of scientific foundations linked to
ultraconservative groups which currently influence American
politics (such as the Heritage Foundation or the Moonies).
The objective of these research centres is to produce
counter-arguments and muddy the waters. If they admit to a global
warming, the "experts" of the George Marshall Coalition or
Institute attribute that to solar forcing. These same "experts" do
not hesitate at the same time to declare that there has not been
any warming, and that the data from IPCC has been falsified.
Climatologist versus Astrophysicists
For other "specialists", coming from the so-called Center for the Study
of Carbon Dioxide & Global Change, the greenhouse effect will even
be ecologicaly beneficial because it favours increased photosynthesis!
Denouncing the lack of seriousness and the scientific independence
of the work of Baliunas and Soon, Mann and his colleagues therefore
decided to refute their arguements one by one in EOS. In producing
a detailed review of the data and the models, they reject the
astrophysicists conclusions and reaffirm the existence of an
anthropogenic component to global warming.
They underline, amongst other points, that the publication of their
response in a peer-reviewed journal demonstrates that there does
exist a strong consensus of scientists with regard to [the causes
of] global warming.

You have also made it onto the junk science website. They reprinted the release, with
the introductory note (approximately), if you believe this they will tell you another!
On the other side, a French news site has proclaimed Mike et al. leaders of the
anti-Bush-because-of -Kyoto brigade. It's only in French, but if you can read it, it's
at [1]

The New Scientist article is here in hard copy form. It isn't on the web site - no
link to it.
It is fair and shows a diagram of the NH and SH (from the GRL paper !!!). Titled
'Climatologists hit back at greenhouse sceptics'.
Fred Pearce didn't call Tim and Keith here earlier in the week. The only call they
got was
from the Sunday Telegraph who may run with something, but they haven't called back.
No-one called me in Japan, so I guess we will have to wait for the GRL article. I'm
from August 2 for two weeks, so I hope you'll get more then. I will be here the whole
of the
July 28 week.
The sceptics have seen it though from the two emails from Timo Hameranta.

Dear Harvey,
Do you know if there has been anything in the press on this yet? I've seen the press
release posted on various outlets on the WEB, and there has been lots of interest from
politicos and other scientists on this. However, the only article that I'm aware of on
this is apparently slated for the July 12 issue of "New Scientist". I haven't seen the
article yet (not available online).
Perhaps Tim, Phil, or Ray have other information.
best regards,

We issued the press release at 3:40 p.m. EDT Monday, July 7. It was sent to 900 science
writers worldwide on our distribution list and posted on EurekAlert!, the AAAS web site
for science press releases.
Almost immediately, we received requests for the full article from The New York Times,
USA Today, National Public Radio, Toronto Star, San Jose Mercury News, Cox Newspapers,
Richmond Times-Dispatch, and four freelancers. It was too late for most Europeans to
receive the release Monday, so we expect additional requests Tuesday morning.
Thanks to all for your help.
