People often ask me if the air in Beijing is as bad as they hear. I usually reply that it's worse, but then find myself having a difficult time describing what a Beijing bad air pollution really looks like.
Now, thanks to the folks at The Asia Society's Center on US-China Relations, I don't have to try to describe it anymore. They've got some photos taken on good days and bad days. Pretty stark contrasts. Pretty scary contrasts.
