As Lorne mentioned in a comment, there’s a small but significant underground buzz on the web suggesting that the US government has weather control weapons and used them to create and direct hurricanes Katrina and Rita. The theories are focused around the High Frequency Active Auroral Research Program (HAARP – link is to its own website).

Here’s one of the sites describing the powers ascribed to HAARP: http://www.haarp.net/. Here’s a key sentence from that site: “Weather modification is possible by, for example, altering upper atmosphere wind patterns by constructing one or more plumes of atmospheric particles which will act as a lens or focusing device.”
I’ve written before about conspiracy theory as an idea and a term. I certainly don’t believe that everything that’s out there is true just because someone believes it. On the other hand, the label ‘conspiracy theory’ has been used to shut down perfectly valid debates around government policies and actions: the whole ‘the evidence of WMD in Iraq is doctored’ ‘conspiracy theory’ is a great example.
Here’s a forum discussion on ‘HAARP steering’ of an earlier hurricane, Charley: http://www.abovetopsecret.com/forum/thread73424/pg1 (apologies for their popup – how’s your blocker?) The discussion actually veers (HAARP steered?) into discussion of the ‘conspiracy theory’ issue as well.
And here’s a (skeptical) discussion of HAARP and Katrina: http://www.abovetopsecret.com/forum/thread167503/pg2.
There’s lots more out there on the net, and it’s well worth checking out – if not because you think weather control is possible, as a case study in human nature.
