Delhi artificial rain: Cloud seeding only SOS measure, says IIT-Kanpur director; technique safe for humans, environment

IIT-Kanpur director Manindra Agrawal clarified that cloud seeding is a short-term emergency tool for severe pollution, posing no threat to humans or the environment. The process uses minute, safe quantities of chemicals like common salt and silver iodide. While recent Delhi trials yielded no rain, they provided crucial data for future improvements, with operations paused due to unfavorable cloud moisture.
