I am not talking about cloud seeding. I am talking about first hand witnessing of targeted suppression of regional summer thunderstorms by high altitude spraying. Of witnessing first hand the rendering of actively building cumulus clouds impotent by stabilizing the upper atmosphere using aerosoling. I am talking about actually stopping entire Pacific Ocean weather systems from reaching southern Oregon and northern California by creating a high pressure Pacific Ocean blocks. The evidence of how these blocks work can still be found in the archives of some anti-geoengineering web sites, btw, although NOAA learned a couple of years ago to scrub such evidence from their publicly available satellite imagery. For the preceding magnitude of weather manipulation as recorded in my weather journals? At least 15 years. Not more that 20. Yet.
