With all of the wierd weather we have been having (floods, drought, etc.) I did some hunting on weather manipulation. As far fetched as it sounds, given the increasing secrecy of our government, it really makes you wonder. If weather can be controlled, think of the power that this would give a few over the entire planet! Global warming or man's manipulation? Who knows. It's worth thinking about at least.
Here are some interesting sites I found.
