A major El Nino storm rolled through Los Angeles this week. Thunder rattled windows, rain flooded city streets, and California’s reservoirs saw levels rise. Part of that was due to cloud seeding, a process where scientists shoot silver iodide into rain clouds, augmenting rainfall. What was the impact of the weather manipulation? What dent might it make in the ongoing drought?
