China's smog levels are so bad flights have been canceled. The U.S. Embassy in Beijing found that the index of fine particulate matter had reached 522 micrograms per cubic meter. That's much higher than it should be; a reading between 300 and 500 is considered hazardous. Andrew Jacobs, Beijing bureau chief for The New York Times, joins the show to discuss.
