Global-warming denial will not save our planet

BOSTON — On the day that the latest report on global warming was released, I went out and bought a light bulb. OK, an environmentally friendly, compact fluorescent light bulb.

No, I do not think that if everyone lit just one little compact fluorescent light bulb, what a bright world this would be. Even the Prius

in our driveway doesn't do a whole lot to reduce my carbon footprint, which is roughly the size of the Yeti lurking in the (melting) Himalayas.

But it was either buying a light bulb or pulling the covers over my head. And it was too early in the day to reach for that kind of comforter.

By every measure, the U.N.'s Intergovernmental Panel on Climate Change raises the level of alarm. The fact of global warming is "unequivocal." The certainty of the human role is now somewhere over 90 percent. Which is about as certain as scientists ever get.

I would like to say we're at a point where global warming is impossible to deny. Let's just say that global-warming deniers are now on a par with Holocaust deniers, though one denies the past and the other denies the present and future.

But light bulbs aside — I now have three and counting — I don't expect that this report will set off some vast political uprising. The sorry fact is that the rising world thermometer hasn't translated into political climate change in America.

The folks at the Pew Research Center clocking public attitudes show that global warming remains 20th on the annual list of 23 policy priorities. Below terrorism, of course, but also below tax cuts, crime, morality and illegal immigration.

One reason is that while poles are melting and polar bears are swimming between ice floes, American politics has remained polarized. There are astonishing gaps between Republican science and Democratic science. Try these numbers: Only 23 percent of college-educated Republicans believe the warming is due to humans, while 75 percent of college-educated Democrats believe it.

This great divide comes from the science-be-damned-and-debunked attitude of the Bush administration and its favorite media outlets. The day of the report, Big Oil Sen. James Inhofe of Oklahoma actually described it as "a shining example of the corruption of science for political gain." Speaking of corruption of science, the American Enterprise Institute, which has gotten $1.6 million over the years from Exxon Mobil, offered $10,000 last summer to scientists who would counter the IPCC report.

But there are psychological as well as political reasons why global warming remains in the cool basement of priorities. It may be,
