BEIJING — In summer, a gray industrial haze coats this city of more than 15 million, descending over the Great Wall, sticking to humid hillsides and obscuring skyscrapers. Soaring temperatures and a lack of wind conspire with gunk-spewing traffic to foul the air.
The pollution is so bad many visitors are wondering how Olympic athletes will be affected and how this city can possibly be ready to host them in less than 10 months.
