Environmental science has become so politicized that its myths endure even after they’ve been disproved. Rachel Carson’s Silent Spring set off decades of chemophobia with its scary anecdotes and bad science, like her baseless claim that DDT was causing cancer in humans and her vision of a mass avian die-off (the bird population was actually increasing as she wrote). Yet Silent Spring is taught in high school and college courses as a model of science writing, with no mention of the increased death tolls from malaria in countries that restricted DDT, or of other problems—like the spread of dengue and the Zika virus—exacerbated by needless fears of insecticides. Similarly, the Left’s zeal to find new reasons to regulate has led to pseudoscientific scaremongering about “Frankenfoods,” transfats, BPA in plastic, mobile phones, electronic cigarettes, power lines, fracking, and nuclear energy....
The long-term risks are certainly worth studying, but no matter whose predictions you trust, climate science provides no justification for Obama’s green agenda—or anyone else’s agenda. Even if it were somehow proved that high-end estimates for future global warming are accurate, that wouldn’t imply that Greens have the right practical solution for reducing carbon emissions—or that we even need to reduce those emissions. Policies for dealing with global warming vary according to political beliefs, economic assumptions, social priorities, and moral principles. Would regulating carbon dioxide stifle economic growth and give too much power to the state? Is it moral to impose sacrifices on poor people to keep temperatures a little cooler for their descendants, who will presumably be many times richer? Are there more important problems to address first? These aren’t questions with scientifically correct answers.
