Could someone ELI5 why a few hundred above ground nuclear explosions today would "wrap the planet in a blanket of soot and block out the suns rays" when post world war America detonated hundreds of Nukes outside Vegas and nothing significant can be said about the environment there?
Yes, the size of the blasts possibly, but the pacific and the siberia tests by the US and USSR were probably much bigger than anything a ballistic missile could carry today, so . . .what are we missing ?
