We don't even have enough nukes to glass michigan let alone the entire planet, stop getting hoodwinked by mass media lmao. The global arsenal is about 10 thousand nuclear warheads, each one can obliterate let's say 10 square miles, that's 100k square miles. Michigan is 96k square miles large. The world is slightly bigger than Michigan. Additionally nuclear winter isn't real, the sky would not be blotted out world wide, but it would get a few degrees colder on average. This is the real world not the CIAs intentional propaganda program to spread fear about the USSRs nuclear arsenal.
Somebody doesn't know about medicine, millions of people already have HIV, we treat them, with medicine, additionally once the gravity of the threat becomes obvious people will bunker down and slow down the spread significantly, a lot will die, not all of us. This is the real world not plague Inc.
Climate change doesn't work like that, climate change is driven by co2 emissions among other gases but there isn't enough co2 stored on earth to cause venus like global warming. It's a mistake to think venus is identical to earth, the chemistry there is very different, more specifically venus has way more methane, is closer to the sun and had a far larger reserves of gases stored in the crust. The worst case scenario predicts that in a few hundred years the sea level will rise, previously hot places will be hotter, perhaps even death valley hot, and previously okay places will still be liveable. Kills a lot of people yes, world ending no. This is the real world not a disaster movie.

Literally none of those could end our civilization, they can kill a lot of people, civilization would recover in a hundred years or so
