Delhi’s Toxic Sky (24 photos)

Toward the end of autumn, parts of northern India and Pakistan are frequently covered by a thick smog caused by a temperature inversion that traps smoke from burning crops, dust, and emissions from factories and vehicles—intensifying some of the worst air pollution in the world. This year the air quality has been particularly poor, with flights being cancelled, schools being closed, and medical authorities describing the situation as a public health emergency in recent weeks. Below, a few images from people navigating the smog in New Delhi, and in Lahore, Pakistan.
