That's the headline of my latest Rocky Mountain News media column, debunking the claim that commercial air travel for long flights causes greater CO2 emissions than would driving a SUV solo the same distance. To the contrary, air travel causes far few per-capita CO2 emissions. Presumably the emissions of most pollutants, such as carbon monoxide, would also be less.

The column also castigates newspapers for running pre-publication reviews of Harry Potter and the Deathly Hallows.

Finally, kudos to Fred Thompson for criticizing the over-federalization of criminal law. Along with Glenn Reynolds, Paul Blackman, and Mike Krause (and sometimes by myself), I've written a variety of articles criticizing over-federalization regarding guns, drugs, and abortion.
