I also do not find Naomi Oreske's arguments too convincing. She does
refer to MIT's famous meteorologist Richard Lindzen as an exception.
But she interprets exceptions as a historian of science in a Kuhnian
way. Perhaps she ought to have been more aware with other types of
understanding exceptions too, as, for instance, the one originating in
classical sociology (John Stuart Mill). In any case, there are much
more environmental sceptics disputing the effects of global warming
and climate change. Let me mention a few examples. One of the leading
contrarians of the scientific consensus on global warming is George
Mason University's atmospheric physicist Fred Singer, who is the
founder of the Science and Environmental Policy Project (SEPP). He
keeps on reassuring the public that future warming will be
inconsequential or modest at most because of the gaps in climate
knowledge that computer simulations reflect. British botanist David
Bellamy also disputes the alarmist scenarios based on computer
modeling. Another famous sceptic (I guess he's more known in Europe
than in the US) is the Dannish controversial environmentalist and
statistician Bjorn Lomborg, who keeps on shouting that it is not worth
spending money on climate change because the effects are expected to
be far in the future and together with a group of six American and two
other economists (including three Nobel prize winners) they have been
recommending that money should be spent on HIV/Aids and free trade
instead of climate change research. Here are some links where you can
find further information about these controversies:,,2087-1612958,00.html,,1331983,00.html,,1810738,00.html

Thus, often in the politics of climate change, it is a commonplace to
hear the concerns about the controversial role played by scientists.
Many claim that it is a very common practice that industry groups try
to find allies among scientists, who would validate their doubts
regarding the alarming science and would lend scientific legitimacy to
the industrial interests (Peter Newell, 2000, Climate for Change:
Non-State Actors and the Global Politics of the Greenhouse, Cambridge
University Press). As a matter of fact, the oil corporation ExxonMobil
funds several think tanks and research programms challenging
mitigation strategies:

Let me finish with this. Jeff Broadbent has already announced in the
socnet mailing list that currently we are designing a policy network
research project to study climate change
through various national policy making processes (Japan, Germany, US,
Sweden, Netherlands, Greece and perhaps others). And I think the
inderdependence among different networks for "believers" and
"contrarians" of ideas about climate change would be an interesting
outcome of our work (this looks pretty similar to Pat Doreian's
analysis of "battling networks" in environmental issues). Moreover, I
believe that a challenging problem would be for us to understand
processes of maniputation through and by scientists. Unfortunately, in
network theory, what is missing is a theorem like the one of
Gibbard-Satterthwaite in social choice. As far as I know, the problem
is that network influence theories are not so useful in cases of
manipulations, hidden agendas or ambiguous strategies. The climate
change policy arena might be an interesting field for us to test new
network ideas and theories about such controversial and complex
