Why, one might wonder, is there such insistence on scientific unanimity on the warming issue? After all, unanimity in science is virtually nonexistent on far less complex matters. Unanimity on an issue as uncertain as "global warming'' would be surprising and suspicious. Moreover, why are the opinions of scientists sought regardless of their field of expertise? Biologists and physicians are rarely asked to endorse some theory in high energy physics. Apparently, when one comes to "global warming,'' any scientist's agreement will do.
Public perceptions, under the influence of extensive, deceptive, and one-sided publicity, can become disconnected from reality. For example, Alabama has had a pronounced cooling trend since 1935. Nevertheless, a poll among professionals in Alabama found that about 95 percent of the participants believed that the climate had been warming over the past fifty years and that the warming was due to the greenhouse effect. Public misperceptions coupled with a sincere desire to "save the planet'' can force political action even when politicians are aware of the reality.
