On one hand many countries will invest in heavy industry, manufacturing, and fall back to fossil fuels.

On the other hand, economy overall should slow down and consumption of non-essential goods and services will drop.

I’m not expecting any definite answers or numbers, of course, just some food for thought.

    War releases MASSIVE amounts of CO2 and green house gasses and destroys casts swaths of green spaces.

    That’s your answer.

        No, because after the war we’ll need to start rebuilding stuff we just destroyed, so the people remaining will increase their emissions many times. Also, hypernormalisation after a war might just render public opinion towards climate change indifferent.

        So imagine if the problem was deforestation and people heating with chopped wood. War means that we’ll burn all their wooden houses down, and then see them cut down even more trees to rebuild them.

        Also, large wars cause baby booms.

    Speed up by far. All the focus will be on producing enough stuff to replace whatever the enemy blows up. Any invention in the renewable department will only come as a result of having used all available fuel already.

    The world population still increased during the previous world wars so unless we have a major nuclear exchange that probably won’t change. If we do have a major nuclear war global warming is suddenly not a big deal anyway.

      I was going to say, it really depends on just how hard we go on the “let’s kill everyone” vibe.

      Also a lot less death more injuries than previous wars. With the same amount or more of environmental destruction.

    We already have a model of this with Israel’s genocide in Gaza wracking up a climate footprint bigger than entire countries. Scale that up to a world war and… Yeah, not fun.

      The tools that would kill enough humans to matter would hurt the biosphere much worse than it hurts humans. Otters and bees don’t have gas masks and nuclear shelters.

      Yes, but the opposite way you might be thinking since mass death from war and other catastrophe is strongly correlated with very high birth rates. We’re on track for the global population to stabilize around 10 billion right now, but if billions die in a world war we will probably go exponential again for a long time.

    Honestly, both outcomes seem equally terrifying. Either we wreck the planet faster through war-driven industry or everything collapses so badly that emissions drop, but at an enormous human cost.

    Most countries don’t have fossil fuels and 28% of oil is offshore. Also heavy industry is very mineral dependent. Let’s be honest, if there will be WW3 most of people will starve to death and start killing and eating each other. Most people don’t know how to get clean water without water pipe. Look how much aid is coming to little country like Palestine to keep them alive. Given that I think it will decrease
