I really am tired of my tech career, and don't think I would mind trying to learn subsistence farming whilst trying to avoid radiation poisoning.

For more information, please consult "Nuclear War Survival Skills" by Cresson H. Kearny.

Also, FTA: "The Robock group’s models are probably overestimating the risk [of nuclear winter]." Citation needed, maybe?

Well the good news is that you can start right now and don't even have to deal with radiation poisoning.

Between the Kuwaiti oil fires of the first gulf war, and many more country-sized forest fire events, we've learned that Nuclear Winter is not a likely scenario. In fact, the very scientists who coined the term in the 1980s have backed away from it.

Nuclear war would be awful, and certainly the radioactive fallout would be bad, and the damage to thriving historical cities, not to mention the human toll. But extinction level? Unlikely.

One thing this pandemic has taught me is the resilience of the modern supply chain to huge unexpected disruption. It's much stronger in that dimension than I initially feared in early March.

What about the Nuclear Winter effect? I would think going like 100 years without being able to grow food would cause everything but the heartiest life forms to die out including humans who are much harder to keep going than simple bacteria.

It's mentioned in the article: their point is basically that it's unlikely, and even if it happened some people somewhere would survive.

There are more factors in a realistic nuclear war:

- Quite a few nuclear weapons will be spent on military sites, which are often in low-population density areas.

- Quite a few nuclear weapons will be used to destroy other nuclear weapons.

- Nuclear fratricide, or nukes from the same side damaging each other in ill-coordinated explosions

- Air defence destroying at least some missiles and especially planes.

- Some bombs will be duds and fail to detonate due to bad maintenance.

When I think about nuclear war leading to human extinction, the first thing that comes to mind isn't any of those 3 mechanisms, but rather economic damage. Not economic damage as in "I lost my retirement investment," but as in "we can't produce enough food." I'd be worried about even much smaller and less deadly nuclear wars leading to massive civil unrest and breakdowns in large-scale social institutions and economies. Mass starvation would be the biggest killer. But I suppose that still wouldn't likely lead to absolute human extinction, but it could certainly lead to a future civilization that is largely unrecognizable to us humans accustomed to industrial or even agricultural societies.
