Beijing's environmental authorities have instituted a bewildering array of measures in hopes of cutting pollution ahead of the 2008 Olympics. They're instituting traffic bans, shutting down factories and unleashing cloud seeders as part of the city's $17 billion anti-pollution regimen.
And yet, at least in terms of air quality, one veteran atmospheric chemist says that China's outsized efforts will have little to no impact on the air. Why? Because Beijing's worst air-quality days are often not the result of human activities, but meteorological phenomena -- namely, the lack of cold fronts pushing across the city from Mongolia.
