Bill, riddle me this. If your reflective mist reflects sunlight won’t it also reflect existant heat? Won’t this turn into a closed-loop effect forever increasing the Earth’s heat?
Bill needs to be put out of his misery and his fortune dedicated to the eradication of others who would save us from ourselves.
Not forever. The particles fall down in a year or two.
Longwave radiation from the stratosphere is insignificant. Gates's particles will warm the stratosphere, just like after Pinatubo. But other than a minor amount of warming during polar winter, the troposphere cooled a lot after Pinatubo. The loss of short wave energy far exceeded the extra longwave energy.
