Collapse of Earth's global water circulation system is already happening
www.earth.com
AMOC is like a massive ocean circulation conveyor belt that moves warm and cold water around the Atlantic. It's failing, and that's very bad.

Don’t think I need to summarize this one. This is bad news for everyone.

    Basically it’s too late to stop the process. Even if we switched to renewables entirely, there will be a lag. That lag is now in a positive feedback loop.

    earlier than initially projected

    There’s that phrase again. If only someone had warned us loudly and repeatedly.

    So, what does this all mean for us? It means we have even less time to get our act together. Reducing emissions isn’t just a good idea — it’s crucial.

    I don’t think this will motivate countries to dramatically increase emissions reduction efforts, but I think it will motivate countries to begin geoengineering. Geoengineering is cheaper and easier than rapid emissions reduction, and the results are more immediate. Yes, it doesn’t solve the core problem, which is the concentration of GHGs in the atmosphere, but it treats the symptom, albeit temporarily. Why put a lot of time, money, and effort into fixing the core problem when you can spend comparatively less time, money, and effort just treating the symptom? Then you can just pretend the core problem doesn’t exist and go about business as usual.

    Edit: sorry, I should have added the /s.

      I don’t think you realize what a collapsed ocean current means for us. This is existential, not business as usual. Anything we do from here on out that isn’t in service of stopping this is signing our species death warrant.

        Haha fricking euros enjoying their moderate climate - wait until they find out what’s real Midwest winter is like. And they want to take my truck and my gas stove? Eff them.

        /too many conservatives probably

    Humanity will be just another dead branch on the tree of life

      Humans are pretty resilient. Adaptable to any climate, even the mess of a climate we created.

      Now, I’m not saying that all 8 billion of us will survive.

      What I’m saying is, the minimum viable genetic population for humans is about 2000 individuals.

        When food runs out for even a portion of those 8 billion, results are gonna be nasty.

        It’s hard to talk about climate initiatives when 1/3 of the planet is shooting eatch other. In worst case with nukes.

        Yep, there will always be humans as long as there is literally anything we can hunt/forage and eat.

        If that will resemble what we perceive as civilisation is another question entirely.

        Right. We survived the ice age with stone age tech.

        Not saying that this makes any of this OK but resilience is absolutely one of humanities highest spec traits.

    As a finn, I can live with -40 °C winters, let them come. At least the invading russians will drop dead like flies in the winter. Again.

    We need to be coordinating human effort across the globe on this above all else. China’s the only one taking it seriously right now.

    The people defending the US tariffs on imports of Chinese solar panels are engaging in straight up climate change denial. We don’t have time for industry protectionism. Once the currents collapse, food chain collapse will follow shortly.

      China is better in implementing countermeasures than especially the USA (also looking to the dark future ahead) but if they would take it seriously they would need to do quit a bit more especially driving something like a global CO2-tax, but AFAIK they were the ones blocking such measures (not that other nations are much better). THIS would be effective.
