In the last week, the air pollution in Beijing has been so severe that it's gone far off the official scale.
In the last several days, the air pollution in Beijing has gone literally off the charts: the levels are so bad that they go well beyond the worst possible rating on the official air quality index. Every day, at roughly the same time, our site China Air Daily documents China’s air pollution in five Chinese cities. I thought the new year had started out well. Beijing, for one, had quite a few clear days with blue skies. Then the new year’s record of clean air was swept away. The air got so bad that friends have told me the filthy air actually has been waking them up in the middle of the night.
