Commentary: Climate Change Isn’t the End of the World
Climate change is often misunderstood as a package deal: If global warming is “real,” both sides of the debate seem to assume, the climate lobby’s policy agenda follows inexorably.
Global warming is not even the obvious top environmental threat. Dirty water, dirty air and insect-borne diseases are a far greater problem today for most people world-wide. Habitat loss and human predation are a far greater problem for most animals. Elephants won’t make it to see a warmer climate. Ask them how they would prefer to spend $1 trillion—subsidizing high-speed trains or a human-free park the size of Montana.
Climate policy advocates’ apocalyptic vision demands serious analysis, and mushy thinking undermines their case. If carbon emissions pose the greatest threat to humanity, it follows that the costs of nuclear power—waste disposal and the occasional meltdown—might be bearable. It follows that the costs of genetically modified foods and modern pesticides, which can feed us with less land and lower carbon emissions, might be bearable. It follows that if the future of civilization is really at stake, adaptation or geo-engineering should not be unmentionable. And it follows that symbolic, ineffective, political grab-bag policies should be intolerable.
