Her comment reflected a common attitude in the Republican Party: Exhaust fumes are as American as apple pie. Cool kids don't need clean air. Arctic ice is overrated.
Republicans like Palin often compete to see who can sound most indifferent to the environment. So someone taking a different tack stands out. Mitt Romney got grief from Rush Limbaugh and others for saying, "I believe the world is getting warmer, and I believe that humans have contributed to that."
This is like noticing that bananas are yellow. Mainstream scientists have said the same thing for a long time. But the consensus has spread.
Bjorn Lomborg, a conservative hero for his 2001 book "The Skeptical Environmentalist," now writes, "We have long moved on from any mainstream disagreements about the science of climate change. The crucial, relevant conversation of today is about what to do about climate change."
In "Climate of Extremes," published by the libertarian Cato Institute, scientists Patrick Michaels and Robert Balling Jr. assail various plans to reduce carbon dioxide emissions. But they admit, "Humans are implicated in the planetary warming that began around 1975. Greenhouse gases are likely to be one cause, probably a considerable one..."
Most GOP candidates, however, don't care. Rick Santorum dismisses such claims as "junk science." Michele Bachmann derides the notion that carbon dioxide could be harmful. Tim Pawlenty's campaign declined to answer when asked if he agrees with Romney.
During last year's campaign, the National Journal reported, "Of the 20 serious GOP Senate challengers who have taken a position, 19 have declared that the science of climate change is inconclusive or flat-out incorrect." (The exception: Mark Kirk of Illinois.)
Conservatives fear liberals will use climate change to justify heavy-handed intrusive regulation and wasteful subsidies, and they are right to worry. But that's no excuse for pretending global warming is a myth or refusing to do anything about it. It's an argument for devising cost-effective, market-based remedies that minimize bureaucratic control.
If today's Republican attitude had prevailed four decades ago, Americans would not have such vital measures as the Clean Air Act and the Clean Water Act. Then, many people worried that environmentalism would strangle economic growth and personal freedom. But both have survived and even flourished.
Conservatives once understood that corporations are not entitled to foul the environment, any more than individuals have the right to dump garbage in the street.
