    RealClimate: New study suggests the Atlantic overturning circulation AMOC “is on tipping course”
    https://www.realclimate.org/index.php/archives/2024/02/new-study-suggests-the-atlantic-overturning-circulation-amoc-is-on-tipping-course/

    The new study by van Westen et al. is a major advance in AMOC stability science, coming from what I consider the world’s leading research hub for AMOC stability studies, in Utrecht/Holland.
    ...
    The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years. This took 6 months to run on 1,024 cores at the Dutch national supercomputing facility, the largest system in the Netherlands in terms of high-performance computing.
    ...
    Now this tipping point has been demonstrated for the first time in a state-of-the-art global coupled climate model, crushing the hope that with more model detail and resolution some feedback might prevent an AMOC collapse.
    ...
    “their estimate of the tipping point (2025 to 2095, 95% confidence level) could be accurate.”
    ...
    Most models even have the wrong sign of this important diagnostic, which determines whether the feedback on Atlantic salinity is stabilising or destabilising, and this model bias is a key reason why in my view the IPCC has so far underestimated the risk of an AMOC collapse by relying on these biased climate models.
    ...
    They show how particularly northern Europe from Britain to Scandinavia would suffer devastating impacts, such as a cooling of winter temperatures by between 10 °C and 30 °C occurring within a century, leading to a completely different climate within a decade or two, in line with paleoclimatic evidence about abrupt ocean circulation changes.
    ...
    Given the impacts, the risk of an AMOC collapse is something to be avoided at all cost. As I’ve said before: the issue is not whether we’re sure this is going to happen. The issue is that we need to rule this out at 99.9 % probability. Once we have a definite warning signal it will be too late to do anything about it, given the inertia in the system.
    ...
    ...
    In the reactions to the paper, I see some misunderstand this as an unrealistic model scenario for the future. It is not. This type of experiment is not a future projection at all, but rather done to trace the equilibrium stability curve (that’s the quasi-equlibrium approach mentioned above). In order to trace the equlibrium response, the freshwater input must be ramped up extremely slowly, which is why this experiment uses so much computer time. After the model’s tipping point was found in this way, it was used to identify precursors that could warn us before reaching the tipping point, so-called “early warning signals”. Then, the scientists turned to reanalysis data (observations-based products, shown in Fig. 6 of the paper) to check for an early warning signal. The headline conclusion that the AMOC is „on tipping course“ is based on these data.

    In other words: it’s observational data from the South Atlantic which suggest the AMOC is on tipping course. Not the model simulation, which is just there to get a better understanding of which early warning signals work, and why.

    Dneska trochu analytičtější článek. Přečetl jsem za vás poslední dvě studie od Ember sledující vývoj na trhu s elektřinou a ukazuje se, že uhlí i plyn jsou v Evropě na značném ústupu. Alespoň teda ve výrobě elektřiny. Naopak slunce a vítr trhají rekordy

    👉 Článek "Evropa využívá čím dál méně elektřiny z fosilních paliv. Stačit to ale nebude" najdete zde:


    Evropa využívá čím dál méně elektřiny z fosilních paliv. Stačit to ale nebude
    https://denikreferendum.cz/clanek/36070-evropa-vyuziva-cim-dal-mene-elektriny-z-fosilnich-paliv-stacit-to-ale-nebude

    Data pro Evropu ukazují, že:
    👉 S koncem uhlí jsme přesně v polovině

    👉 Uhlí ve výrobě elektřiny pokleslo meziročně o 26 %, plyn o 15 %

    👉 Emise ze sektoru energetiky klesly o 19 %, což je víc než za covidu

    👉Vítr poprvé překonal plyn. Z větru jsme v Evropě vyrobili 19 % elektřiny, z plynu 18 %

    👉 Klíčový je výrazný nárůst solární a větrné energie. Druhým faktorem bylo snížení spotřeby energie zapříčiněné energetickou krizí

    👉 Německo snížilo emise o rekordních 21 %

    👉 Dokonce uhelný gigant Polsko se odklání od uhlí. Pomalu, ale jistě

    👉 Nic z toho stačit nebude ke zvládnutí klimatické krizi

    When those such as @RogerHallamCS21 have warned that billions could die, he's been widely attacked for misrepresenting the science.

    So what does the science actually say? Well nothing really, there is no realistic science about this. No one is actually studying it.

    How will our system, our civilization, respond to those climate and ecological shocks, and how will it change the human system's ability to support and sustain the current population?

    Absolutely no one knows or is attempting to research that. Not even enough to make a guess.

    Things like the 2008 financial crash, demonstrate just how vulnerable our system is to in-built wobbles, let alone major changes and shocks to our system, from things such as climate change, ecosystems and biodiversity decline, parameters which wholly sustain our economy.

    What we need to understand is that our present system, is a system, totally reliant on lots of underlying processes, and that any change to these underlying processes, parameters, would profoundly change our whole civilization.

    Climate, and ecological shocks, will profoundly change how our system operates, our political systems, our governance, our economy, the financial system, and our societies i.e. our people and their attitudes. Nothing will be unchanged, and all will be radically altered.

    ...

    To be clear about this, climate science doesn't study the stability of our civilization, to climate shocks.

    Yes, climate science, looks into sea level rise, extreme weather, future climates, but this tells us nothing about the state of our civilization, in response to this.

    So if a climate scientist assures you it will not be catastrophic, they are not offering any sort of scientific opinion, because they've never studied the impacts on our societies and civilization, and how they'll respond to these shocks. They're just personal opinions.
