TAYLOR EXCERPT In his new book, The Assault on Reason, Al Gore pleads, "We must stop tolerating the rejection and distortion of science. We must insist on an end to the cynical use of pseudo-studies known to be false for the purpose of intentionally clouding the public's ability to discern the truth." Gore repeatedly asks that science and reason displace cynical political posturing as the central focus of public discourse. If Gore really means what he writes, he has an opportunity to make a difference by leading by example on the issue of global warming. A cooperative and productive discussion of global warming must be open and honest regarding the science. Global warming threats ought to be studied and mitigated, and they should not be deliberately exaggerated as a means of building support for a desired political position. Many of the assertions Gore makes in his movie, ''An Inconvenient Truth,'' have been refuted by science, both before and after he made them. Gore can show sincerity in his plea for scientific honesty by publicly acknowledging where science has rebutted his claims.
