Weather modification warfare

[Mystic74]

So I was thinking.. in Civ III, the climate would change after too many uses of atomic weapons.. so how about creating a HAARP weapon tech and unit that would modify a target's land at will? changing grasslands to tundra, or plains to flood plains, or locally making shores disappear by changing land to water, or replacing land by desrt tiles.. Anyone willing to help develop a MOD that would do that? I never coded for Civ yet..
