This is the board for you if you wish to discuss or explore conspiracies of any kind, historical or current.
I know about HAARP and other such systems, currently we have no evidence any of them are used to influence the weather, but but i would not deny the possibility, but then this would be very local events and not general/global climate events.
"Climate change" is already used to explain disasters and yes this will continue in the future, even when it has nothing to do with it.
Large superstorms for instance are caused by the interaction of the Earth with the Sun and the amount of charge we receive. We are still at the mercy of nature.
