Why try this above Sweden and not above some African country where they suffer more from heat?
It's all under one stratosphere bro. This is one if the worst suggestions I've seen.
Probably the chalk dust will disperse all over the stratosphere instead of settling on the ground, but still Africa sounds like a better choice for a planet cooling experiment.
Or just don't do it at all?
Wait.. are you Bill Gates? Do you want this to happen?
