Yeah, because we all know how well that worked any of the several times we've tried it, that are documented:

Sarcasm, in case that's not obvious. There's always, theoretically, a non-zero chance that they actually figured it out at some point, and that they've only published the results they want us to see. Sure. I will believe that just as soon as I see a mountain of hard evidence to prove it. From what I can find, though, they've been pretty transparent about their attempts at modifying the weather, and that they still don't know how, and that we probably shouldn't hold our breath waiting for them to figure it out.
