In January, I teamed up with Vice News to explain why cloud seeding is entirely unrelated to floods.“ Conspiracy theorists don’t understand scale,” I explained. That discussion is very relevant tonight. Cloud seeding is for a tiny cloud — not a 4,000,000,000,000 gallon flood. | Matthew Cappucci

Artificial rain, also known as cloud seeding, is a process designed to induce precipitation by dispersing substances into the air that serve as cloud condensation or ice nuclei. The most common method involves the use of silver iodide, potassium iodide, or liquid propane, which acts as cloud seeding agents. These substances are typically dispersed into the atmosphere by aircraft or ground-based generators. When introduced to the clouds, they encourage the formation of ice crystals or water dropl
