A leading climate scientist says the CIA approached him to ask for information on how to disrupt the weather.
Professor Alan Robock said he received a call three years ago from two men wanting to know if experts would be able to spot a hostile force’s attempts to upset the US climate. However, he claimed the real intention was to find out how feasible it might be to secretly interfere with the climate of another country.
The professor, from Rutgers University, New Jersey, has investigated the potential risks and benefits of using stratospheric particles to simulate the climate-changing effects of volcanic eruptions.
He said: “I told them, after thinking a little bit, that we probably would because if you put enough material in the atmosphere to reflect sunlight we would be able to detect it and see the equipment that was putting it up there.”
Designed by BAE Advanced Technologies, its purpose was to analyse the ionosphere, a region of the upper atmosphere, with the aim of developing better radio communications technology.
HAARP was a target of conspiracy theorists, who said it was used for weather modification, to cause earthquakes, tsunamis and the disappearance of Flight MH370. In May 2014, the US Air Force notified congress that it would be closing down the programme.
Russian cloud seeding
The Russian government is said to have used rain prevention methods since Soviet times, seeding clouds three times a year during Victory Day, City Day and Russia Day.
Ahead of each public holiday, the Russian Air Force often dispatches up to 12 cargo planes carrying loads of silver iodide, liquid nitrogen and cement powder to seed clouds above Moscow and empty the skies of moisture.
