A combination of two photographs shows a view of the Forbidden City in Beijing taken July 28 (L) and on August 2, 2008 (R). Beijing has vowed the Olympic Games will take place under blue skies, not the murky "sauna" haze that has shrouded the city recently, but even on apparently clear days pollution levels may not be safe for athletes.

A general view of the Beijing skyline on a clear day in Beijing August 2, 2008. Beijing has vowed the Olympic Games will take place under blue skies, not the murky "sauna" haze that has shrouded the city recently, but even on apparently clear days pollution levels may not be safe for athletes.
In this image reviewed by the Chinese military, a power station is seen through haze in Beijing Saturday Aug. 2, 2008.
