Seitz signed the 1995 Leipzig Declaration and, in an open letter inviting scientists to sign the Oregon Institute of Science and Medicine‘s global warming petition, called for the United States to reject the Kyoto Protocol. The letter was accompanied by a 12-page article on climate change which followed a style and format nearly identical to that of a contribution to Proceedings of the National Academy of Sciences, a scientific journal, even including a date of publication (“October 26”) and volume number (“Vol. 13: 149–164 1999”), but was not actually a publication of the National Academy. In response the United States National Academy of Sciences took what the New York Times called “the extraordinary step of refuting the position of one [of] its former presidents.” The NAS also made it clear that “The petition does not reflect the conclusions of expert reports of the Academy.”
