People in the poll show they really don't know what a nuclear winter will be like. Even the run up to the nuclear winter will be rough. Ya can have brass balls all ya want and think you'd go survival mode but ya have to know what you're in for. The film The Day After shows a small hint of what the immediate after effect would be but it fails to show what the months and years (if you make it that long) will be like. No food will grow, summer will be lost at least for one year. Look at the impact the Valcona in Iceland had on Europe's climate in 2010/11 winter and multiply it by 50. Then as the dust settles and still processing inosing radiation mixed in with the top soil... you can't use the top soil to sew crops that you were using. You'd need to plow everything and turn up the soil from as low as possible without machinery all while starving and still radiation sick if you're holding together. You never know when you'll come across an accumulation of radiation and get sick again. Everyone will get cancer in the years after and without modern health tech, even the young who'll be born with severe disabilities and cancers will happen early and a lot and be not be able to take on the harshness of the new world.
Best thing you can do is when you feel it in the air that nuclear war may happen is get on a plane and take one to New Zealand and go back packing armed with some survival skills, the southern hemisphere is the only hope for nuclear winter. If you can survive the mild New Zealand climate you should do well.
Here's The day after to know just exactly what you'll go through in the Northern hemisphere in the weeks after a full exchange and expect it to be worse as close to the bombs as this film stake place, this film is likely what more rural areas away from the bombs will suffer.

^ Give me the sweet instant death in the blast.

Still staying true to the name, I see.

It's why I choose it but in this case it's legit. I've done much deep dives into this iceberg and it's a rough one. It comes down to irratiated dust to make it simple and once all those cities end up irradiated in the atmosphere we are fucked.

It's not a nuclear war that will end civilization as we know it. The slow moving danger of climate change will do that over time.

People react to shocking events like the chance of nuclear war. But stay complacent when there's no immediate visible danger.

Civilizations come and go. There's evidence of many civilizations preceeding ours, to 13,000 years back

Most of that is speculation yet Göbekli Tepe can't be denied

We're not that smart really, can't even figure out how people 13,000 years ago put those T shaped pillars there

Earliest footprints discovered are from 150,000 years ago. Humans will survive another ice age. Earth survived much worse.

Yeah, the natural systems will bring it back over time. But that may take a few ten thousand years.

And yeah, world hunger, genocide and war are still major problems we also need to address.

All I know is that UP is massively underrated.

No, the trees failed to create the usual amount of biomass. Might be a problem of plant stressors, maybe too dry.

It might be even more extinction events that we don't have enough evidence of. But yeah, the biosphere will keep going. But in a major extinction event humanity is likely to go as well. I think this is what some people worry about.

If Antarctica thaws then we are in deep shit. The South Pole has some geographic quirks that keep it extra cool. So it will not thaw with just 2° warming, it needs more.
