Okay so we've established that neither my imagination, nor the labors of the Intergovernmental Panel on Climate Change are any good for determining how likely we are on course for nuclear war.

You know that humans do have nukes, right? And a long history of killing each other over pretty much anything? (from land rights to idealogies and everything in between).

So in your estimation, who would be a good source to determine how/whether humans get to a point where nuclear war is a likely scenario?

I explained to you what the SSPs are.

Why the obsession with nuclear war and trying to get totally imprecise scenarios there? They serve very little purpose other than building scary narratives. Some people's job is to worry about them, but that doesn't mean they are central to what we should do.

When a hurricane strikes, things are usually not just Lord Of The Flies - the idea of collapse into violent chaos is a popular one but doesn't really happen much.
