Is it theoretically possible to alter the weather - perhaps to use as a
weapon. There was an article on the internet about America supposedly
inserting certain chemicals into the atmostphere to divert hazardous
weather to targetted countries. Although I believe this to be fiction -
if theoretically possible - I would appreciate some assistance in
articulating this for a proposed novel i am researching... please note
- I am a complete novice so scientific responses in lay-man terms
please.

If we told you we'd have to kill you.
