Is Climate Change a Scientific Controversy?

Retreat of Athabasca Glacier in the Canadian Rockies, 1919-2005 (photos from different angles, but most of the foreground of the recent picture was covered by ice in 1919)

In my previous post, I made some comments on a report that I hadn't read on dinosaur extinctions, and had some questions instead about the researchers (41 of them) who had produced the paper for the journal Science. Bryan at In Terra Veritas gently suggested that the sheer number of authors might be a form of appeal to authority, that is, if enough experts/famous people/authorities say it, it must be true. An appeal to authority in philosophical circles is considered a logical fallacy in many circumstances, and in science this can include situations where a scientist makes a fallacious claim because he/she has a financial stake in the outcome (a new medicine works really well, for instance, or cigarettes don't cause cancer). On the other hand, the citing of peer-reviewed research is an appeal to authority that is considered a proper form of evidence in a scientific debate.

These thoughts were tumbling about in my mind that I ran across two interesting lists (via Daily Kos and the Wonk Room at Think Progress) that represent a sort of appeal to authority. It involves global warming and climate change, and the question of the role of humans in the rising temperatures that are beginning to overwhelm ecosystems across many parts of our planet. The news media have been in the practice of presenting the controversy as a scientific one. Is it? Is there no real consensus between scientists? The first of these is a list of organizations, not just individual scientists, who accept the evidence that global warming is a human-caused phenomenon requiring action (bear with me for the length of the list):

The second list is a group of organizations who say, based on their involvement as petitioners versus the U.S. Environmental Protection Agency, that human-induced climate change is a fraud (often with accusations that scientists are just after grant money for research):

American Petroleum Institute
US Chamber of Commerce
National Association of Manufacturers
Competitive Enterprise Institute
Industrial Minerals Association

Massey Energy
Alpha Natural Resources
Southeastern Legal Foundation
Georgia Agribusiness Council

National Oilseed Processors Association
National Petrochemical and Refiners Association
Western States Petroleum Association

One could add to this list, of course, Senator James Inhofe, Sarah Palin, Rush Limbaugh, Glen Beck, and all of the other "climate scientists" in the Senate and in political theatre. The next time climate change is presented as a scientific controversy needing a balanced response by the "other side" of the issue in the mainstream media, consider who has the short-term financial interest in the political outcome. And consider who stands to lose in the long run, as the glaciers continue to melt, sea level continues to rise, droughts continue to devastate vast regions, and agricultural production is disrupted.
