The Council of the National Academy of Sciences (NAS) is concerned about the confusion caused by a petition being circulated via a letter from a former president of this Academy. This petition criticizes the science underlying the Kyoto treaty on carbon dioxide emissions (the Kyoto Protocol to the Framework Convention on Climate Change), and it asks scientists to recommend rejection of this treaty by the U.S. Senate. The petition was mailed with an op-ed article from The Wall Street Journal and a manuscript in a format that is nearly identical to that of scientific articles published in the Proceedings of the National Academy of Sciences. The NAS Council would like to make it clear that this petition has nothing to do with the National Academy of Sciences and that the manuscript was not published in the Proceedings of the National Academy of Sciences or in any other peer-reviewed journal.

The petition does not reflect the conclusions of expert reports of the Academy.

In particular, the Committee on Science, Engineering, and Public Policy of the National Academy of Sciences, the National Academy of Engineering (NAE), and the Institute of Medicine (IOM) conducted a major consensus study on this issue, entitled Policy Implications of Greenhouse Warming (1991,1992). This analysis concluded that " ...even given the considerable uncertainties in our knowledge of the relevant phenomena, greenhouse warming poses a potential threat sufficient to merit prompt responses. ... Investment in mitigation measures acts as insurance protection against the great uncertainties and the possibility of dramatic surprises." In addition, the Committee on Global Change Research of the National Research Council, the operating arm of the NAS and the NAE, will issue a major report later this spring on the research issues that can help to reduce the scientific uncertainties associated with global change phenomena, including climate change.
