    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    Budoucnost čistší, levnější, s novými pracovními místy a nulovými emisemi. Dostupné elektromobily pro všechny a zemědělství respektující přírodu. Tak popisuje rok 2050 Matthias Buck, odborník na energetickou politiku z německého think tanku Agora specializujícího se na energetickou tranzici. A kromě toho vám prozradí, jak vypadá takzvaný planetární jídelníček a jak často si v budoucnu budeme moct dovolit steak.

    China creates vast research infrastructure to support ambitious climate goals
    https://www.nature.com/articles/d41586-021-03491-6

    Carbon-neutrality institutes, and other initiatives to support a pledge to achieve net zero by 2060, are popping up like mushrooms across China.
    ...
    Already this year, more than ten prominent universities and institutions have set up carbon-neutrality-research institutes; the Chinese Academy of Sciences launched a centre last month.
    ...
    The country is experiencing a “national movement”, says Wu Libo, an environmental economist at Fudan University in Shanghai, as companies, regional governments and academia shift gears.
    ...
    Carbon capture and sequestration technologies will also be important to achieving China’s goals, according to the documents, and could be another focus for researchers. There is also a plan for electric and hybrid vehicles to make up 40% of those sold by 2030. Much more detail is expected to come in future documents, say researchers.

    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

    people v mann ,)

    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.
