This hits a lil closer to home. This summer I lost my home when half our town burnt down in a 32,000 hectare forest fire. The other half is untouched and there's not even soot on the town, nevermind into the atmosphere. Massive amounts of boreal forest burn yearly. So their scenario is pure speculation with zero basis in reality.

It's speculation shared by nuclear and climate scientists.

15 million hectares burned in Canada alone in 2023. We average over 2 million hectares of burnt forest per year.

Some quick maths. 15 million ha is 150,000km2. Tsar Bomba blast area was 16km2. It would take over 9000 Tsar Bombas to burn as much forest as only Canada's 2023 forest fire season.

Maybe provide some source for your assertion...

The fire burns beyond the blast area.

Also, urban fires produce

Link 1 is talking about blast effect which is a different topic altogether, link 2 is paywalled and is a magazine, not anything scholarly.

One, no—it’s about fire effects. It’s in the title.

Two, you literally cited blast area to estimate burn area.

Three, do you need a source for fires being able to spread? If I toss a match into a dry forest, is the area of the matchhead a predictor of particulate volume?

What I'm saying is... Tens of millions of hectares burn all the time, far more than all the nukes on earth would likely set on fire (since most of the populous cities on earth are on the coasts, and there's roads, farms and prairies surrounding most, not forests), so this idea that nukes would start forest fires that launch soot into the air that end civilization is pure fiction. There's zero basis for it, tens of millions of hectares worldwide burn yearly and it's barely noticeable if you don't live next to it.
