Debra J. Saunders — a conservative commentator for the SF Chronicle, who occasionally used to be smart and snarky and worth paying attention to but is now mostly stupid and snarky — just wrote this column about global warming that I had to respond to. The gist of it is that (a) a few scientists don’t agree with the human-caused global warming theory, therefore there is no scientific consensus about it; and (b) cow flatulence creates more greenhouse gases than auto emissions, therefore we don’t have to worry about reducing auto emissions.
I wrote a letter to the editor in response, but they didn’t run it. I’m not annoyed — I know they get a zillion letters, and in fact the response they did run (third from the top on the Letters page) was a good one. But my letter was good too, dammit, and I thought y’all would like to see it. So here it is. Enjoy!
Debra Saunders’ column about global warming (12/12/06) makes it clear that she has no idea what science is, or how it works. The fact that a handful of scientists don’t believe in human-caused global warming doesn’t undercut the theory — any more than the handful of AIDS denialists undercuts the theory that HIV causes AIDS. Serious disagreement within the scientific community is not the same as an overwhelming scientific consensus disputed by a handful of cranks.
And her argument about cows is just silly. The meat industry is as much a product of human civilization as the auto industry. If cow flatulence creates more greenhouse gases than auto emissions, it’s hardly an argument against reducing auto emissions. If anything, it’s an argument for reducing the consumption of beef.
One final note: I would just like to point out that a Google image search for “cow fart” yielded 87 results. An additional 20 for “cow flatulence.” Impressive. Not as startling as the 453 results I got from “sexy fishing” (see The Aging Slut), but not bad.
