There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution. Since the correctness or fallacy of that conclusion has immense implications for public policy and for the future of the biosphere, we thought it appropriate to present a debate within the pages of P&S concerning that conclusion.
and the inclusion of an article critical of anthropogenic theories of global warming. I wouldn’t make very much of it, the editorial seems carefully worded and the article is prefaced with this:
The following article has not undergone any scientific peer review. Its conclusions are in disagreement with the overwhelming opinion of the world scientific community. The Council of the American Physical Society disagrees with this article’s conclusions.
Based on my conversations with climate scientists, I think there’s much better reason to question future projections of global warming than there is to question analyses of what’s happened already.
UPDATE: This clarification, currently on the APS home page (no permalink), seems to prove my point:
The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007:
“Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth’s climate.”
An article at odds with this statement recently appeared in an online newsletter of the APS Forum on Physics and Society, one of 39 units of APS. The header of this newsletter carries the statement that “Opinions expressed are those of the authors alone and do not necessarily reflect the views of the APS or of the Forum.” This newsletter is not a journal of the APS and it is not peer reviewed.
