Delhi's Hope for Cleaner Air: Artificial Rain to Tackle Toxic Smog

Indian scientists are planning to seed clouds in an attempt to trigger heavy rain and alleviate the severe smog and air pollution in New Delhi, the world's most polluted capital. The project, estimated to cost $120,000, involves spraying a mix of salts, including silver iodine, into clouds to encourage rainfall. The local government has already implemented measures such as school closures and restrictions on vehicle use to combat pollution. The air quality index in Delhi is currently categorized as "hazardous." The scientists hope that the cloud seeding will result in heavy and widespread rain to wash away pollutants, but light rain could worsen the situation.
