See photos of the haze. 06.20.13 2:12 PM ETJoseph Nair/AP If you’re in Singapore today, you should probably stay indoors. Air pollution in the city-state has hit levels so dangerous that officials are urging residents to stay inside, and flight controllers at nearby airports are taking extra precautions. In neighboring Malaysia, hundreds of schools were closed for the day. The cause of the haze? Singapore officials blame Indonesia, where local farmers are taking part in a yearly tradition of burning forests in order to prepare land for planting. Indonesia, however, isn’t taking this sitting down. “Singapore shouldn’t be like children, in such a tizzy,” one Indonesian official was reported saying. Indonesians also point out that Singapore and Malaysian companies own many of the Indonesian farms that are burning. Whatever the cause, the Pollution Standard Index in Singapore sits at 371 on Thursday. The previous high was 226—and anything over 300 is bad for you. See photos of the smoggy capital.
