Bill Gates Funds Solar Geoengineering: Plans to Release Chemicals into the Stratosphere

CNBC, 2019: "Bill Gates is among a dozen individual donors... backing the first stratospheric solar geoengineering experiment."

"A high-altitude balloon will lift instruments about 20km into the stratosphere, where it will release... chemicals, like calcium carbonate and sulphates, and then measure the change in atmospheric chemistry and light scattering."

"Nozzles still need to be designed that can continuously blast out trillions of particles, and scientists still need to decide what chemicals those particles should be made of."

"Unlike cloud brightening, which is another solar reflection technique, the tech needed for stratospheric injections is not far off."
