Hi dear @lupafilotaxia
I am also a conspiranoic at heart and I think that the HARP project is for the climate, although officially they are antennas to study the phenomenon of the aurora borealis, I believe that humans have changed the climate for a long time, when we began to divert the rivers then to build artificial islands, now we also want to control the rain, I guess scientists are close to that, there is already an atmospheric bombardment technique that makes it rain.
greetings
