    Are Intergovernmental Alliances for Saving Humanity Still Possible?
    https://jembendell.com/2021/11/08/are-intergovernmental-alliances-for-saving-humanity-still-possible-part-5-of-a-realgreenrevolution/

    Geoengineering, nuclear power, ecocide, climate finance, migrating ecosystems... I cover a bunch of often controversial topics in the 5th instalment of my essay on a #RealGreenRevolution, which I offer to contrast with the agenda discussed in and around #COP26. Feedback welcome (not with any illusion that these ideas go somewhere towards policy, but in search of better understand)

    Cop26: world on track for disastrous heating of more than 2.4C, says key report | Cop26 | The Guardian
    https://www.theguardian.com/environment/2021/nov/09/cop26-sets-course-for-disastrous-heating-of-more-than-24c-says-key-report

    Temperature rises will top 2.4C by the end of this century, based on the short-term goals countries have set out, according to research published in Glasgow on Tuesday.

    The estimate stands in sharp contrast to optimistic forecasts published last week that suggested heating could be held to 1.9C or 1.8C
    By contrast, the sobering assessment of a rise of 2.4C from Climate Action Tracker (CAT), the world’s most respected climate analysis coalition, was based on countries’ short-term goals for the next decade.

    Emissions will be twice as high in 2030 as they need to be to stay within 1.5C, based on promises made in Glasgow, CAT found.

    The findings should serve as a “reality check” to the talks, said Niklas Höhne, one of the authors. “Countries’ long-term intentions are good, but their short-term implementation is inadequate,” he told the Guardian.

    1bn people will suffer extreme heat at just 2C heating, say scientists | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2021/nov/09/1bn-people-will-suffer-extreme-heat-at-just-2c-heating-say-scientists

    The Met Office assessed wet-bulb temperature, which combines both heat and humidity. Once this measure reaches 35C, the human body cannot cool itself by sweating and even healthy people sitting in the shade will die within six hours.

    If efforts to end the climate emergency fail and temperatures rise by 4C, half of the world’s population will suffer from this extreme heat stress.

    COP26: The energy transition is here to stay and battery storage is essential to it - Energy Storage News
    https://www.energy-storage.news/cop26-the-energy-transition-is-here-to-stay-and-battery-storage-is-essential-to-it/

    We have the technological tools to decarbonise, but can we do so at pace and scale? It depends on the politics, says James Basden, co-founder and director of Zenobe Energy, a UK-headquartered company working on clean energy infrastructure including grid-scale battery storage and fleet transport electrification solutions.

    ...

    But make no mistake: even if negotiations flounder, the energy transition is here to stay.
    ...
    Spooked by the risks of inaction, 45% of banks disclosing to CDP — the global environmental impact disclosure non-profit group — have aligned their portfolios with net zero. This empowers green technology companies.

    ...

    Despite the pandemic, 260GW of new renewable generation was deployed globally in 2020 – smashing former records by almost 50 per cent. The electric vehicle (EV) sector raised US$28 billion, 10 times more than in previous years.

    Cédric Durand, Energy Dilemma — Sidecar
    https://newleftreview.org/sidecar/posts/energy-dilemma

    A successful carbon transition implies the harmonious unfolding of two processes complexly related at the material, economic and financial levels. First, a process of disbandment must take place. Sources of carbon must be drastically reduced: above all hydrocarbon extraction, electricity production by coal and gas, fuel-based transport systems, the construction sector (due to the high level of emissions involved in cement and steel production) and the meat industry. What is at stake here is degrowth in the most straightforward sense: equipment must be scrapped, fossil fuel reserves must stay in the soil, intensive cattle-breeding must be abandoned and an array of related professional skills must be made redundant.

    All things being equal, the elimination of production capacities implies a contraction of supply which would lead to generalized inflationary pressure. This is even more likely because the sectors most affected are located at the commanding heights of modern economies. Cascading through the other sectors, pressure on costs will dent firms’ mark-up, global profits and/or consumer purchasing power, unleashing wild recessionary forces. In addition, degrowth of the carbon economy is a net loss from the point of view of the valorization of financial capital: huge amounts of stranded assets must be wiped out since underlying expected profits are foregone, paving the way for fire sales and ricocheting onto the mass of fictitious capital. These interrelated dynamics will fuel each other, as recessionary forces increase debt defaults while financial crisis freezes the access to credit.

    The other side of the transition is a major investment push to accommodate the supply shock caused by the degrowth of the carbon sector. While changing consumption habits could play a role, especially in affluent countries, the creation of new carbon-free production capacities, improvements in efficiency, electrification of transport, industrial and heating systems (along with the deployment of carbon capture in some instances) are also necessary to compensate for the phasing out of greenhouse gas emissions. From a capitalist perspective, these could represent new profit opportunities, so long as the costs of production are not prohibitive relative to available demand. Attracted by this valorization, green finance could step in and accelerate the transition, propelling a new wave of accumulation capable of sustaining employment and living standards.

    Yet it is important to bear in mind that timing is everything: making such adjustments in fifty years is completely different from having to disengage drastically in a decade. And from where we are now, the prospects for a smooth and adequate switch to green energy are slim, to say the least. The scaling back of the carbon sector remains uncertain due to the inherent contingency of political processes and the persistent lack of engagement from state authorities.

    ...

    Market mechanisms are expected to internalize the negative externalities of greenhouse gas emissions, allowing for an orderly transition on both the supply and demand sides. ‘Carbon pricing has the advantage of focusing on efficiency in terms of cost per ton of CO2, without the need to identify in advance which measures will work.’ Reflecting the plasticity of market adjustment, a carbon price – ‘unlike more prescriptive measures’ – opens up a space for ‘innovative solutions’.

    This free-market, techno-optimistic perspective ensures that capitalist growth and climate stabilization are reconciliable. However, it suffers from two main shortcomings. The first is the blindness of the carbon-pricing approach to the macroeconomic dynamics involved in the transition effort. A recent report by Jean Pisani Ferry, written for the Peterson Institute for International Economics, plays down the possibility of any smooth adjustment driven by market prices, while also dashing the hopes of a Green New Deal that could lift all boats.

    Observing that ‘Procrastination has reduced the chances of engineering an orderly transition’, the report notes that there is ‘no guarantee that the transition to carbon neutrality will be good for growth.’ The process is quite simple: 1) since decarbonation implies an accelerated obsolescence of some part of existing capital stock, supply will be reduced; 2) in the meantime, more investment will be necessary. The burning question then becomes: are there sufficient resources in the economy to allow for more investment alongside weakened supply? The answer depends on the amount of slack in the economy – that is, idle productive capacity and unemployment. But considering the size of the adjustment and the compressed timeframe, this cannot be taken for granted. In Pisani Ferry’s view, ‘Impact on growth will be ambiguous, impact on consumption should be negative. Climate action is like a military build-up when facing a threat: good for welfare in the long run, but bad for consumer satisfaction’. Shifting the resources from consumption to investment means that consumers will inevitably bear the cost of the effort.

    YMLADRIS: No i kdyby to tak bylo, nic to nezmění. Rozhodující je, co uděláme následujících 10 let. COP26 celkem jasně ukazuje, že nic moc, budeme dál pálit fosil a necháme na dětech, jak si s tím potom poradí. Žádné vymahatelné závazky, každý bude dělat, co uzná za vhodné. Tj. zadrátujeme ploty, párty pokračuje. Do 20 let přijde globální krize a investice do fúze budou mimo hru. Mnohem větší smysl mi dává snaha o soběstačnost, OZE do každé vesnice, nespoléhat na velké dodavatele, blackouty budou.
