A new statistical model has predicted that the collapse of Atlantic Ocean currents is likely to occur this century. The results would cause catastrophic temperature drops in the Northern Hemisphere, but other scientists are not so sure.

Researchers have predicted the collapse of the AMOC could happen any time between 2025 and 2095 — far sooner than previous predictions, although not all scientists are convinced.

What if…

    Actions that work in the possible world in which it collapses soon are actively harmful in possible worlds in which it doesn’t. Acting as if a threat will happen only makes sense if the action isn’t significantly harmful in cases where it doesn’t, where significantly is based on the harm of not being prepared and the chance of it happening.

    If the Gulf Stream will collapse by 2025, the response isn’t to be more eco-friendly. In fact, it’s the opposite. Everyone in the north should prepare to burn a lot more fuel, and concern for global warming would definitely be reduced. Global warming is something you can only afford to give a shit about when temperatures haven’t just dropped by 3.5C and you haven’t just lost 78% of your arable land (UK figures, because that’s where I live).

      Do you mean that people need to see how their life will get worse before they will be willing to act? That sounds a little accelerationist to me. But I’m not entirely sure of your argument. You seem to be saying that people would not be worried if they lost 4/5ths of their arable land, but I think I must be misunderstanding something.

      (I think it’s s tributary to the Gulf Stream that is at risk of collapsing, not the Gulf Stream itself, which, I’m told, is based on the earth’s rotation rather than climate.)

        You are. People would be very worried. It’s just that their worry would not be expressed in attempts to improve things in the long-term when there’s a short-term disaster.

        If the Gulf Stream will definitely collapse in 2025 (which is not what the study says), then that’s too soon to do anything about, so the priority is surviving it rather than preventing it. Fundamentally, things that help prevent disaster are not the same as things that help survive it.

          I see, yes, that makes more sense: if conditions get that bad that quickly, it won’t be a question of preventing worse change, it’ll be figuring out how to survive day-to-day.
