Please. If you don't mind, I'd rather not let government get into the business of trying to control the weather once it has the technological capability.
They already control the world's rivers and lakes. Without that technology about 5 billion of us would die from starvation. I have no problem adjusting the weather if it becomes needed to sustain life. No one is studying the right question though. We're too busy wondering if humans alter the earth. Yes we do, and what of it? We should focus on what we want to alter it to. A new Ice Age may not be such a good idea. We're better off in the other direction. The real question is: what temperture do we want and how do we get and stay there? A Luddite approach isn't useful.
