I read that Beijing's air quality made the international headlines today. Rightly so. Here are views outside our window. Between the buildings is a beautiful spire that glows red at night. I use that spire as a subjective guide to the air quality. Objectively I rely on a quantifiable index called AQI (Air Quality Index) which peaked out at 646 today. Needless to say, we stayed inside today. The latest reading indicates the numbers are beginning to drop, currently to 404. Still too high for good health. Pray for strong winds to come.
