"The U. N. Convention on the Prohibition of Military or any other Hostile Use of Environmental Modification, which went into effect 5 October 1978, applies only to 'widespread, long-lasting or severe' environmental modifications.
-Local, non-permanent changes, such as
precipitation enhancement, hail suppression

Since 1978 the official Air Force position has been that weather modification had little utility or military payoff as a weapon of war. The official Air Force position needs to be reevaluated:
-In the light of 19 years of scientific advances
-In the light of advanced weapon systems
which are more environmentally sensitive
-To prepare against technological surprise"

I totally believe the government can control the weather. Not totally, but they are getting better at it. I felt that way for awhile and I have not researched it or anything.

I guess I shouldn' say government, it is the iluminati (probably spelled it wrong). In my opinion.

Yeah it was quite real look into "Project Popeye" in Vietnam all real though just how effective it was is debatable.

As aecreate mentioned though Hostile Use of Weather control has been internationaly banned for quite some time. It would clearly have huge peaceful beneifits and countries are free to pursue it for that reason and there still isnt any practical way to effect it in any major way.

Even theories on how it could be done require insane amounts of energy like 10-100% percent of the US total energy production if you wanted to heat the ionosphere to change weather patterens.
