    Public investment - How to get infrastructure right | Leaders | The Economist
    https://www.economist.com/leaders/2021/01/02/how-to-get-infrastructure-right

    Every country wants to build more bridges, roads and renewable-power grids. It won’t be easy

    ...

    First, governments should select projects systematically by creating a single list and picking those with the highest payback. This assessment should factor in externalities, including the impact on carbon emissions, and delays, which are a big source of cost overruns. And it should be carried out by bodies that are independent from those that build and run assets. Often the projects selected will not be the glittering new temples that politicians like their names on, but humble repairs and maintenance.

    The second lesson is to harness the private sector. Not only is it a source of capital—global infrastructure funds have over $200bn waiting to be deployed—but projects with private investors also tend to be managed better. That means developing standardised contracts and independent regulators that protect taxpayers but also give investors reasonable certainty of an adequate return.

    Both lessons might seem obvious. A few places, such as Chile and Norway, get infrastructure right. But over half of the countries surveyed by the imf do not maintain a national pipeline of projects. And in most the record is staggeringly erratic. America is splurging on 5g (see article) but has squalid airports and too little renewable energy. Europe has shiny airports and wind farms but is in the stone age on 5g. Infrastructure is one of the last local industries left where easy gains are still to be had by copying others around the world. If you benchmark public investment in over 100 countries, adopting best practice could make spending 33% more efficient. The prize is huge.

    YMLADRIS: tak jako vzdy, snazime se, co nejvice palit drevo pro vyrobu tepla, ale letos jsme prioritizovali zmenu systemu vytapeni z elektriny na plyn pred dalsimi snahami ve zvysovani tepelneho odporu.
    Vzhledem k tomu, ze velkovyrobci elektriny nedokazi odchod od uhli urychlit a stale se jeste najde dost lidi, kteri si mysli, ze ani 2038 neni realny a ze pro nej ani neexistuje duvod. Tak jsem se priklonil k tomu, ze plyn sice neni nizkoemisnim zdrojem tepla, ale na prechodne obdobi 10-20 let snizi emise mnohem lepe a rychleji nez lidi pochopi, ze jim skutecne musi ridit prenos elektriny a produkci pocitace.

    UPDATE 5-Argentina suspends corn exports to ensure domestic food supplies | Reuters
    https://www.reuters.com/...tina-suspends-corn-exports-to-ensure-domestic-food-supplies-idINL1N2JA1MN

    Dec 30 (Reuters) - Argentina will suspend sales of corn for export until Feb. 28, the agriculture ministry said on Wednesday, announcing the surprise move as part of the government's effort to ensure ample domestic food supplies

    The move by the world's No. 3 corn supplier was a sign of tightening global food supplies during the COVID-19 pandemic.

    "This decision is based on the need to ensure the supply of grain for the sectors that use it as a raw material for the production of animal protein such as pork, chicken, eggs, milk and cattle, where corn represents a significant component of production costs," the statement said.

    Argentina's government is struggling to control food price inflation and help low-income families contending with an economy shrinking during the pandemic. Buyers can still book corn from Argentina, but only for a shipping date March 1 or later.

    Russia this month announced a grain export quota and wheat tax as President Vladimir Putin criticized rising food prices.

    And major agricultural exporter Brazil has imported staples, including soybeans. Chicago Board of Trade corn futures notched a 6-1/2-year high on Wednesday after Argentina's announcement.

    The South American grains powerhouse is also a big international soybean and wheat supplier, as well as the world's top exporter of soymeal livestock feed.

    The weaponization of misplaced defeatism & doomism reflected in the discourse of "deep adaptation" is a tactic in the ongoing war on climate action. Unsurprisingly, the movement has been nurtured by climate inactivists. Read about it at length in The #NewClimateWar: https://t.co/sFbCbMa0gA

    Initiative for Leadership and Sustainability: Facts on Deep Adaptation in response to a New York Times style article
    http://iflas.blogspot.com/2020/12/facts-on-deep-adaptation-in-response-to.html?m=1

    Some people may be ignoring evidence of how an anticipation of collapse has inspired climate activism and are instead projecting onto people how they might feel and act if they anticipated collapse themselves. That is not to deny that the psychological implications of anticipating collapse are huge and incredibly important for all of us who wish to slow climate change and prepare for further disruptions in the future. I will therefore continue working with psychologists to invite informed and open discussion of the implications and what we can all do to help, and intend to share more on that in the coming weeks. The seriousness with which the DA Forum takes these matters is illustrated by their safety and wellbeing policy, support for grief tending, and advice on seeking professional help when in distress. It is also why its approach to facilitating gatherings involves space for emotional expression and processing. That is contrary to some of the suggestions in the NYT article.

    Initiative for Leadership and Sustainability: Facilitation for Deep Adaptation- IFLAS Occasional Paper 6
    http://iflas.blogspot.com/2020/11/facilitation-for-deep-adaptation-iflas.html?m=1

    In this paper some of the aspects of Deep Adaptation facilitation that have emerged from a community of practice of volunteer facilitators are summarised. These aspects include containment, with the intention of enabling co-responsibility for a safe-enough space for difficult conversations to occur with difficult emotions. Another key aspect is welcoming radical uncertainty in response to the anxieties people feel, as their sense of self, security and agency are challenged by the anticipation of collapse. A third aspect of this facilitation is making space for grief, which is welcomed as a natural and ongoing response to our predicament. A fourth aspect is a curiosity about processes of othering and separation. That arises due to our assessment that a seemingly innate process of imagining separation, and therefore ‘othering’ people and nature as less significant or meaningful, has been a habit in modern society that impedes responses to social and environmental crises.

    Three specific modalities are summarised. First, Deep Listening groups are small gatherings in which participants are invited to share honestly and openly about how they are feeling, and what they are experiencing, as they grapple with the implications of the unfolding climate tragedy. Crucially, they are not dialogic. Second, Deep Relating circles invite people into a relational meditation practice, or an approach to relating with others in a way that is grounded in a detailed awareness of present moment experience. Third, Death Cafes provide a safe and confidential setting for people to talk about death and dying, so with that awareness they might clarify what they want to do with their finite lives. Many other modalities are emerging in the Deep Adaptation field, which can be found from the links provided in the paper.

    Initiative for Leadership and Sustainability: Facts on Deep Adaptation in response to a New York Times style article
    http://iflas.blogspot.com/2020/12/facts-on-deep-adaptation-in-response-to.html?m=1

    The NYT article includes a comment from Dr Kate Marvel that is presented as a criticism of the science in the DA paper and yet does not relate to what is in my paper. I paste in a relevant section of the paper and the article below. I do not confuse albedo effect and tipping points. I cite experts on the albedo effect and a study on how much radiative forcing arises from ice loss. This criticism is used in the NYT article as the basis for implying that the field of collapse anticipation is based on faulty science. One could argue against the scientific basis for collapse anticipation in more informed and nuanced ways that might aid our understanding of our situation. However, the way the article treats the topic reflects an approach that over 500 scientists and scholars have recently criticised as unhelpful suppression of the discussion of collapse risk and readiness. It also suggests a conflict between scholars which might not actually exist, and simply be misunderstandings of what one or the other has written or said. It is unfortunate that people reading the NYT might think I dismiss Dr Marvel or any climatologist, when the quoted sentence was within my explanation about the importance of seeking granular expertise on specific matters. Therefore, in clarifying this, I would like to confirm that I do not disrespect or disregard the work of Dr Marvel, or any other climatologist, but still encourage journalists to look further than the most famous names in the broad field of climatology when engaging in contentious aspects of climate change. For instance, it is quite easy to contact the scientists I referenced in the paper on albedo and the Arctic.


    The NYT article talks about DA implying it is too late to ‘save the world’. Neither myself or anyone I work with uses that frame or phrasing. Such a phrase reflects a set of anthropocentric patriarchal assumptions about the world and the human relationship to it. Perhaps some people assume that current industrial consumer societies constitute the only “world” worth “saving”. Following the work of Sheldon Solomon, perhaps that reaction is because these societies are the ones that have been the source of our identity, and as we become more anxious, unless we support each other's equanimity, we become more attached to our existing stories of identity, belonging and purpose. That is why it is so important to listen to the insights of indigenous scholars and people who work with them, such as Professor Vanessa Andreotti, who is on the holding group (advisory board) of the DA Forum. It may also be a reason why the DA Forum itself recently questioned the ‘save the world’ framing in their most recent review of where the Forum is now at since I left it in September. It is also why loosening our attachment to stories which affirm our separation and superiority with the rest of creation are central to the ethos of DA activities, as we explain in detail in a recent paper.

      2020 Changes in North Atlantic atmospheric circulation in a warmer climate favor winter flooding and summer drought over Europe
      https://journals.ametsoc.org/view/journals/clim/aop/JCLI-D-20-0311.1/JCLI-D-20-0311.1.xml

      Our paper “Changes in North Atlantic atmospheric circulation in a warmer climate favor winter flooding and summer drought over Europe” is now released online in Journal of Climate:

      We used a very high resolution climate model (GFDL CM2.6: gfdl.noaa.gov/cm2-6/) to assess changes in atmospheric circulation patterns under an experiment of increasing carbon dioxide concentrations

      The high resolution of the model allows for mesoscale oceanic eddies to be resolved and it has a realistic representation of the AMOC. This is important for the ocean-atmosphere interactions that play a significant role in forming the dominant atmospheric circulation patterns

      ...

      we find robust changes in certain atmospheric circulation patterns over the North Atlantic

      In winter (and particularly in February), zonal regimes (NAO+ like) are increasing by ~30% in frequency in the 2xCO2. In summer (and particularly in August), Atlantic Ridge, a high-pressure system off the UK coast, is increasing by ~60%

      Those robust changes in a warmer world may have great implications for European climate. In winter the increase of zonal circulation is linked to increased rainfall over northwestern Europe, increasing the risk of flooding in the area

      In summer, the increase of the AR is linked to less precipitation and longer dry spells over western and central Europe, contributing to higher drought risk. Those dynamical changes act supplementary to the thermodynamic effects of a warming world, exacerbating the impacts

      Could the reconstructed proxy data curve hide a 100-year warming spike as in the 20th Century, due to the averaging process over time and space? Three reasons why this is extremely unlikely:

      Tady bych si dovolil uvést taky nějaký argument aby nebylo naše očekávání přehnané.

      Kritika: Některá tvrzení navrhovatelů regenerativního zemědělství byla kritizována jako přehnaná a nepodložená důkazy některých členů vědecké komunity. Allan Savory, jeden ze slavných zastánců regenerativního zemědělství, ve svém projevu o TED prohlásil, že celostní pastva může snížit hladinu oxidu uhličitého na předindustriální úroveň v rozpětí 40 let. Podle Skeptical Science „není možné zvýšit produktivitu, zvýšit počet dobytka a ukládat uhlík pomocí jakékoli pastevní strategie, bez ohledu na celostní management [...] Byly provedeny dlouhodobé studie o vlivu pastvy na ukládání uhlíku v půdě. provedeno dříve a výsledky nejsou slibné. [...] Vzhledem ke složité povaze ukládání uhlíku v půdě, zvyšující se globální teplotě, riziku dezertifikace a emisím metanu z chovu hospodářských zvířat je nepravděpodobné, že by celostní management nebo jakákoli technika řízení , může zvrátit změnu klimatu. “ Podle studie z roku 2016 zveřejněné University of Uppsala je skutečná rychlost, jakou by zlepšené řízení pastvy mohlo přispět k sekvestraci uhlíku, sedmkrát nižší než tvrzení Savoryho. Studie dospěla k závěru, že holistické řízení nemůže zvrátit změnu klimatu. Studie Food and Climate Research Network z roku 2017 dospěla k závěru, že Savoryho tvrzení o sekvestraci uhlíku jsou „nereálná“ a velmi odlišná od tvrzení vydaných recenzovanými studiemi.

      2019 Toward a General Theory of Societal Collapse: A Biophysical Examination of Tainter’s Model of the Diminishing Returns of Complexity
      https://link.springer.com/article/10.1007/s41247-018-0049-0

      The collapse of large social systems, often referred to as “civilizations” or “empires,” is a well-known historical phenomenon, but its origins are the object of an unresolved debate. In this paper, we present a simple biophysical model which we link to the concept that societies collapse because of the “diminishing returns of complexity” proposed by Tainter (The collapse of complex societies, Cambridge University Press, Cambridge, 1988). Our model is based on the description of a socio-economic system as a trophic chain of energy stocks which dissipate the energy potential of the available resources. The model is based on the idea that we observe that the exploitation of a non-renewable resource stock (“production”) has a strongly nonlinear relation with the complexity of the system, assumed to be proportional to the size of the stock termed “The Economy” (or “capital”), producing various trajectories of decline of the economy, in some cases rapid enough that they can be defined as “collapses.” The evolution of the relation of production and the economy produces a curve similar to the one proposed by Tainter, for the decline of a complex society
