Delhi is grappling with its annual air pollution crisis, with Air Quality Index (AQI) levels in the “severe plus” category, consistently above 450. In response, Delhi’s Environment Minister Gopal Rai has appealed to Prime Minister Narendra Modi for assistance in deploying cloud seeding a controversial technique to induce artificial rain and potentially reduce pollution levels.
What is Cloud Seeding?
Cloud seeding, also known as artificial rain, involves dispersing substances like silver iodide, potassium iodide, or dry ice into clouds to stimulate precipitation. These particles act as nuclei around which water droplets form, potentially triggering rainfall. The process can be carried out via aircraft, rockets, or ground-based generators.
In theory, the rainfall generated could "wa...
