Actually, there may be something to this.. mostly spraying aluminum and barium to control rainfall. Some speculate to either flood, or dry out large areas of a country to wreck their economy.
There's been a few symposiums held by scientists discussing this, and recently Monsanto has come out with an aluminum resistant seed.. and why would this be needed?
The most recent Symposium was held in Maui last month, and some very well respected scientists were involved. I had read a very interesting 5 page article they had written up detailing a lot of the high points, but I can't find it again...
Here is one small blurb I could find though...

If you don't think this hasn't been done, you need to look back during the cold war times when they were spraying from high altitudes over the US to study how chemical warfare could be used, and how the clouds would travel and fall over a large area. This has been proven and admitted to in senate hearings back in 77
One more thing to consider. Some very true facts in this.

If you think you're government cares about you enough to not use you as a guinea pig, then I got some blackened money I need you to transfer for me.
