Satellite images show toxic smog over South Asia visible from space

Nasa satellite images from November 18, 2024, showed a thick smog covering several South Asian cities including the Indian capital New Delhi and the Pakistani cities of Lahore and Karachi. The region’s blanket of smog is an annual crisis blamed on farmland stubble burning, factories and car exhaust. Authorities have imposed restrictions to curb pollution, but many residents still face severe health risks.
