The conspiracy theories often imagine cloud seeding as some weather control superweapon that can create catastrophic floods or droughts. In reality, you're just giving water droplets or ice crystals something to condense around (usually silver iodide particles). You're working with what nature has already provided and you can't conjure storms from nothing or dramatically amplify them.

But hey, maybe it's better limit your knowledge about a subject to just its name. It enables you to be afraid of things you don't understand. Some people crave that feeling.
