The Los Angeles Times reports that Beijing’s smog makes Los Angeles air look good.

“Comparing California 30 years ago to China today is apples and oranges,” says Eugene Leong, an air pollution expert and former executive director of the Assn. of Bay Area Governments who has been teaching at Peking University for several years. “How bad was PM2.5 in California in the ‘60s, ‘70s and ‘80s?
