Not sure this would be Russia's rationale behind starting an exchange considering how much they would benefit from global warming through the unlocking of farmland and livable territory.

And likewise, not sure it would favor the United States all that much either since 1/8th of our landmass is in Alaska. It'd probably be a wash for the US but certainly Russia has no reason to use nuclear weapons to halt or reverse global warming.

I could see this conspiracy theory being slightly more believable for an exchange between India and Pakistan, though. And by slightly, I mean only mildly less laughable.

ironically.. it seems like just a mild little nuclear winter would offset our increases of global warming. yay!

thats called geoenginbering and it can be done by spreading particles from airplanes.

Thousands of lifes and millions if not billions affected to various degree in order to slightly cool down our planet (I think the point of reducing emissions is not to prevent global warming but to rather keep the air we breathe not too contaminated?)? Jokes aside, maybe the nuclear tests in the 30s,40s and 60s were the reason why the globe has become slightly colder to begin with, and what is being observed now is just out planet recovering from a reasonably rough century of forceful cooling down inflicted by nuclear events?
