A nice idea but I don't think it's really practical. Humanity itself doesn't really have the capability to bring that level of energy output and control to bare on a planetary scale. Moreover, I don't think it's really a very interesting problem. To use an analogy, your idea is similar to the approach used in AI in the 70s or 80s -- computer scientists trying to build a complete artificial intelligence from scraps. In the past 30 years we've learned that this isn't the right approach to a massive problem that we don't truly understand. Instead, we should focus on building small advances -- pieces which get us toward our overall goal. Instead of attempting to control the weather, we need to focus on smaller goals like practical fusion power, a highly advanced national electrical grid, or advanced solar power.
