But on a day like Saturday, the discrepancy between official readings and independent ones hardly seemed to matter; you didn't need a weatherman to know which way the ill wind blew. Or failed to blow, as the case may have been. One expert quoted by Chinese media attributed this spike in pollution to a series of windless days that allowed pollutants to accumulate.
But wind can be a problem when it does blow, too. In the outlying provinces that are part of Beijing’s airshed, there is a great deal of heavy industry. Pollution regulations are much harder to enforce there. And, in this colder-than-average winter, people have been burning more coal and wood than usual.Cleaning this up will clearly be expensive, and will raise the cost of living in Beijing, and the cost of doing business with China, which is probably why the government has moved slowly. But, at some point, the real environmental costs of China's economic "miracle" will have to be dealt with.
