Anthropogenic global warming is a scientific hypothesis, not an article of religious or ideological dogma. Skepticism and doubt are entirely appropriate in the realm of science, in which truth is determined by evidence, experimentation, and observation, not by consensus or revelation. Yet when it comes to global warming, dissent is treated as heresy — as a pernicious belief whose exponents must be shamed, shunned, or silenced.
Newsweek is hardly the only offender. At the Live Earth concert in New Jersey last month, Robert F. Kennedy Jr. denounced climate-change skeptics as “corporate toadies” for “villainous” enemies of America and the human race. “This is treason,” he shouted, “and we need to start treating them now as traitors.”
Some environmentalists and commentators have suggested that global-warming “denial” be made a crime, much as Holocaust denial is in some countries. Others have proposed that climate-change dissidents be prosecuted in Nuremberg-style trials. The Weather Channel’s Heidi Cullen has suggested that television meteorologists be stripped of their American Meteorological Society certification if they dare to question predictions of catastrophic global warming.
Personally, I don’t think holocaust denial should be criminalized either. It’s stupid and completely detached from reality (sort of like global warming zealotry!), but free speech means free speech.
