Thanks OG. i have a great deal of respect for you, based on your years of creative posts here, writing important rarely phrased angles on topics, especially calling for respect to indigenous people's voices and cultures and lands.
It's interesting that the links at the Weather Modification Association site you link, are about renewed efforts at cloud seeding, in the face of climate chaos and intense droughts. This certainly provides evidence of governmental and capitalist interest in weather modification, including by California and by China. But cloud-seeding for rain-making (with targeted delivery of chemically inert silver iodide) is an entirely different practice from what is propounded by the "chemtrails" argument (with massive dispersal of highly toxic metals).
Cloud seeding itself is a bad idea, certainly on the massive scale that California and China are considering, which will obviously produce further natural imbalance and vast collateral damage (rain that falls somewhere, does not fall somewhere else, etc.). Such programs can only add fuel to the fires of climate chaos.
To frame my thoughts:
The government and its sponsors commit outrageous crimes, upon a long legacy of outrageous crimes, against humanity and nature. It is tragically likely that - as climate chaos continues to accelerate its perturbations - the self-inflated egos who bestride "the system" will grasp at geoengineering "solutions." Barring imminent system collapse, as disaster piles on top of unprecedented human and Earthly disaster, it will become obvious to "leaders" that the only "rational" way to address impending omnicide caused by "accidental" geoengineering (merely in genocidal pursuit of wealth and power throughout the industrial and fossil fuel eras), is by attempting intentional geoengineering - ultimately, the complete management of the planet's ecology - "to save humanity."
But none of that framework is evidence of - nor provides an explanatory narrative for - a massive program of spraying metals. i remain highly skeptical.
