The beauty of such things is that people believe what they want to believe. hence causes much debate.
Believing vs Knowing
I don't see any possibly debate in this
Facts are one thing, believing is...i dont know how to call it.
I can belieive in pink elephants hanging on my ceiling, but that does not make much sense...
Now...for the HAARP
Originally , HARP was made as research of ionosphere project. It should help communicate with submarines anywhere on the world, without posibillity of jamming. Basically it should make one giant transmitter of ionosphere.
That requires huge amount of energy and really can disturb atmosphere in radius of few hundred kilometers. Russians also experimented with similar stuff.
But...it's the question what actually this means. Does it mean that HAARP can change climate anywhere on the world, or it can just make visible effects on local level.
Conspiracy guys think it can, and their opinion is based on questionable researches of "experts".
So, until we had more data, more REAL data, we can't actually talk about it...we can just guess and risk to make ourselves funny.
So far, there are much better ways to control weather conditions on one area.
During the Allied Force in 1999. (spring time, 78 days) There where only few days with clouds and rain. Normaly in Belgrade often rains in that time of year. Few times i even saw for myself clouds disappearing. You could see a dot in cloud, and it would expand until whole sky was clear. Few minutes later airraid begins.
And this is not top secret project, or alien technology, just special projectile with proper stuff in it. I think they are based on barium, but not shure...
This is cheap, and as we can see this is effective. Much cheaper then consuming huge amounts of power in HAARP.
