    TADEAS: P. Maidowski

    Why this is important: all our models build on wishful assumptions that need to be revisited. Can’t do that if Mann, who doesn’t understand the human predicament, constantly dumbs down the climate conversation

    The climate community can’t waste time in-fighting. We should not call scientists who warn of collapse “doomers”. We should support their bravery. Most scientists are running to the hills with their families. These ones care enough about you to stay & tell the truth.

    An important PETITION: Celebrity climate communicator, Professor Mann must stop downplaying the severity of our predicament, labelling experts, activists and concerned citizens who disagree either 'doomers' and/or 'bad actors'.

    TADEAS:

    The central underpinning concept of this study therefore differs from the conjecture in other studies that certain locations may be ‘preserved’ as lifeboats through deliberate action (i.e., by governments or other groups). Instead, the formation of any ‘node of persisting complexity’ would be through system behaviour arising from certain starting conditions, i.e., is an analysis of an evolutionary process that would occur largely outside of direct human control. This description has some similarities with the ‘Regenerative Bioregions’ concept [65] in which future localised populations may persist through their overall biophysical demands matching regional ecological conditions and carrying capacities.

    ...

    The methodology for assessing which nations have the potential to form ‘nodes of persisting complexity’ utilises the outputs of the ‘University of Notre Dame—Global Adaptation Index’ (ND-GAIN) study, which assessed and ranked all nations in terms of vulnerability and readiness to future environmental change. The ND-GAIN ranking was screened against additional semi-quantitative measures specifically related to the ‘nodes of persisting complexity’ concept to generate a ‘shortlist’ of five nations (New Zealand, Iceland, the United Kingdom, Australia (Tasmania) and Ireland). Each of these was then further qualitatively assessed for their individual, local-scale (primarily energy and agricultural) characteristics. This identified New Zealand as having the greatest potential to form a ‘node of persisting complexity’, with Iceland, Australia (Tasmania) and Ireland also having favourable characteristics. The United Kingdom presents a more complex picture and potentially has less favourable characteristics overall.

    Sustainability | Free Full-Text | An Analysis of the Potential for the Formation of ‘Nodes of Persisting Complexity’
    https://www.mdpi.com/2071-1050/13/15/8161

    Human civilisation has undergone a continuous trajectory of rising sociopolitical complexity since its inception; a trend which has undergone a dramatic recent acceleration. This phenomenon has resulted in increasingly severe perturbation of the Earth System, manifesting recently as global-scale effects such as climate change. These effects create an increased risk of a global ‘de-complexification’ (collapse) event in which complexity could undergo widespread reversal. ‘Nodes of persisting complexity’ are geographical locations which may experience lesser effects from ‘de-complexification’ due to having ‘favourable starting conditions’ that may allow the retention of a degree of complexity. A shortlist of nations (New Zealand, Iceland, the United Kingdom, Australia and Ireland) were identified and qualitatively analysed in detail to ascertain their potential to form ‘nodes of persisting complexity’ (New Zealand is identified as having the greatest potential). The analysis outputs are applied to identify insights for enhancing resilience to ‘de-complexification’.

    The GeGaLo index: Geopolitical gains and losses after energy transition - ScienceDirect
    https://www.sciencedirect.com/science/article/pii/S2211467X19300999

    2019

    This article presents the GeGaLo index of geopolitical gains and losses that 156 countries may experience after a full-scale transition to renewable energy. The following indicators are considered for inclusion in the index: fossil fuel production, fossil fuel reserves, renewable energy resources, governance, and conflict. Some of these represent potential gains; some represent losses; and some the capacity of countries to handle changes in geopolitical strength. Five alternative versions of the index are developed to work out the optimal design. First, the energy resource indicators are combined with equal weights to create two simple versions of the index. Next, governance and conflict indicators are included to create three more complex versions of the index. The index provides useful pointers for strategic energy and foreign policy choices: geopolitical power will be more evenly distributed after an energy transition; Iceland will gain most; Russia may be one of the main holders of stranded geopolitical assets; China and the USA will lose more geopolitically than foreseen by other analyses. The index also indicates a lack of emphasis in parts of the literature on space for renewable energy infrastructure and on domestically sourced coal for the current strength of countries such as China and the United States.

    XCHAOS: Hlavní problém s CCS je "scale" a čas. Žádná technologie nedokáže během 50 let odstranit tolik CO2, kolik potřebujeme, museli bychom postavit průmysl podobného rozsahu jako je fosilní infrastruktura a celý by musel být dotovaný (z čeho?), sám nevydělá nic (pokud nepočítáš CO2 do limonád, ale to není CCS).
    Kdyby CCS někdo myslel vážně, tak výsledkem COP26 bude zákaz spalování uhlí bez CCS, takhle je to jen greenwashing.
    Dobře je to popsané v tomhle videu:

    XCHAOS: v principu (v realite se to treba muze podarit jinak) je tu odlisnost tech ekosystemovych cyklu (jejichz soucasti je puda, drevo, sklenikovy plyny produkovany zviratama) a procesu lidsky civilizace, ktera do systemu dodava ten fosilni uhlik a dalsi prvky a slouceniny a tim ho destabilizuje. carbon capture ekosystemem je podle me v principu zmateni, protoze ano, chceme, aby toto ekosystem delal, ale vzdy jsou to jen nejakej vice nebo mene dlouhe cykly, ktere chceme podporovat a tim ekosystem re/generovat... nikdy tim ale nemuzeme vyvazit to dodavani fosilniho uhliku a dalsich prvku nebo sloucenin do systemu, tzn. carbon-capture se sice potkava s ekosystemovou regeneraci v jednom aspektu, ale principialne je CC spis fosilizace, ktera ma ten prvek z toho kolobehu vyjmout [na hodne dlouho].

    Proč jsem sem ty videa dal, když můj názor na carbon capture je víceméně dlouuhodobě jasný: tedy, např. jsem si pořád plně neuvědomil význam toho, že koncentrace CO2 v mořské vodě je zhruba 150x větší, než ve vzduchu. Získávání CO2 z mořské vody ohřátím na 70 stupňů pomocí solární energie v subtropických oblastech mi nepřijde až tak dramatické, takže tohle by mohla být určitá stopa. Závažnějším problémem zůstává "kam s ním?"... pyrolýza zemního plynu za vzniku vodíku a grafitu mi najednou jako až tak úplný nesmysl nepřijde. Nejlepší by ale bylo dokázat CO2 uložit přímo do podoby uhlíkatých vláken, které budou zabudované v předmětech dlouhodobé spotřeby... tedy tak trochu napodobit to, co dělají stromy s celulózou, ale jinak.

    Jinak u toho požadavku carbon capture na 100 let mi přijde, že vyhrát musejí nutně dřevěné konstrukce přímo dimenzované tak, aby stavba měla prokazatelně životnost 100 let, tzn. byla navržená tak, aby neshnila, neshořela, apod. Pokud něco dotovat, tak bych fakt dotoval dřevostavby všeho druhu: zkrátka přímo zdanit beton a přímo z toho odměňovat cokoliv zkolaudované, co je postavené ze dřeva - a ideálně to odměňovat kontinuálně, tedy dotace bude vyplácena v průběhu sto let za každý další rok trvání existence té dřevěné konstrukce (ne, že se to někomu prodá a ten to zbourá). Ideální forma emisních povolenek mi po bližším přezkoumání přijde taková, že odměňováni mají být kontinuálně (ne nárazově) ti, kdo prokazatelně skladují dřevo a výrobky z něj - ale zase, záleží pak na původu toho dřeva, takže jsme v bludném kruhu, kdy systém dotací bude vždy nějakým trikem zneužitelný...

    Možná systém vyplácení dotací "na dřevo" (tedy, myšleno "za dřevo"), ale po nějakém počtu let trvání dřevěné konstrukce? Tedy odměňovat ne předem, ale až za uhlík, který prokazatelně nějaký počet let byl mimo atmosférický oběh? Ovšem zase: společenské náklady na vynucení takového systému odměňování ekologických investic budou enormní... (ve smyslu neochoty populace na tom participovat....)

    Open Call: Soils as Sites of Emergency and Transformation, NESS Conference, Gothenburg, Sweden. Abstract deadline 15 Dec! – The Posthumanities Hub
    https://posthumanitieshub.net/2021/11/18/open-call-soils-as-sites-of-emergency-and-transformation-ness-conference-gothenburg-sweden-abstract-deadline-15-dec/

    The Covid-19 pandemic is seen by some as the latest warning against the intensity of intervention of human worlds into non-human processes and spaces. This latest emergency unfolds, however, against the background of the long and accelerating process of human-induced, global planetary and ecosystem change variously debated as the Anthropocene, the Capitalocene, or the Plantationcene.

    The most lasting, the most fundamental, and the least address aspect of this ‘slow emergency’ and ongoing transformation relates to soils. When (rarely) discussed in the public sphere, soils are framed as an object of concern, and their degrading state is seen as a cause for alarm (as exemplified e.g. by the creation of the EU Mission for Soil Health and Food). In the Nordic context, soil emergencies are particularly noticeable as global heating-related changes in soil functions and states are having sudden and profound effects on lives, livelihoods, and land-use and inhabitation futures.

    Such emergency framings which underpin policy and expert concern around soil change can, however, lack historical and ontological reflexivity around the desired human-soil relations. Beyond this emergency framing, soils are also a site of and a source of transformation. Both historically and today, soils are active participants in the making of human societies and of ecologies. Whereas loss of soils has been linked with societal collapse, reciprocal relations of care can transform societies and ecosystems. Moreover, in contemporary thinking in political and social theory (e.g. Bruno Latour’s Down to Earth, Donna Haraway’s thinking on composting), arts (e.g. the Humus economicus project), and in debates about sustainable farming (e.g. regenerative agriculture), relations with soils are a source of inspiration for new models of human-environmental interaction and for conceptualising more-than-human health. This new wave of ‘thinking with soils’ works across disciplinary boundaries to reconceptualise people, environments, and their interactions by acknowledging and interrogating human entanglement with soils.
