Here is a view of the Beijing area ( top left center ) on Christmas day, 2007. This is the worst I've ever seen it ( although I haven't really been looking lately ) but the pollution is there is often shockingly bad. The type of thing the EPA is harping on in AZ is 1/100 or even 1/1000 as bad. To me, the gloss of Chinese pollution in public discussion is an outrageous fact in itself.
