    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.

    The open web in the implementation of real adaptation to climate change - Myles Byrne
    https://neuroplastic.github.io/climate_social_contract_2020.html

    To ethically respond to the climate crisis at all, the GenX, Millenial, & GenZ generations have to act as one, and route around nation-states and the institutional framework built around them.

    The basics of this collective action have been described as ‘WWII with everyone on the same side’. The basics of what this entails are obvious, and will not be surprising to anyone who has been paying adequate attention to our collective situation:

    universal conscription into global service
    rapid universal cessation of further carbon extraction
    rapid universal sequestration of carbon
    universal redistribution of resources on a global scale to effect 1–3

    How these basics are to be implemented is non-obvious, and is the focus of this document.

    It is natural to assume that some form of global political institution has to be planned, organised, and ratified through a legal process, in order to implement these steps. However, the combinatorial explosion of the negative synergies we face, and the logistics and mobilisation required in steps 1–4, have already defeated conventional institutions.

    A defensible path to implementation would require a system enabling continual, integrated, iterative adaptations across local-global scales. Such a system already exists, in full technical implementation, in the form of the global internet and open web.

    The first step on the path to implementation of real adaptation to climate change is to transfer the legal status of humans, from that of being the subjects of nation-states, to being autonomous agents in a formally open web.

    tohle zni slibne. a samotny zvyseni pH pudy muze "usetrit" az 20% pudy

    https://www.nature.com/articles/d41586-020-01965-7

    Achieving targets for mitigating global warming will require the large-scale withdrawal of carbon dioxide from the atmosphere. Writing in Nature, Beerling et al.1 report that enhanced rock weathering in soils has substantial technical and economic potential as a global strategy for removing atmospheric CO2. When crushed basalt or other silicate material is added to soil, it slowly dissolves and reacts with CO2 to form carbonates. These either remain in the soil or move towards the oceans. The authors argue that this method would enable between 0.5 billion and 2 billion tonnes of CO2 to be removed from the atmosphere each year. This rate is similar to that of other land-based approaches2, such as the accrual of organic carbon in soil, carbon capture and sequestration in geological formations, and the addition of biochar (a carbon-rich material) to soil.

    ...

    Increasing soil pH alone would substantially boost crop yields in many regions of the world, because it is possible that low pH constrains crop production on more than 200 million hectares of arable and orchard soils3. This area is equivalent to about 20% of the total extent of these soils (967 million hectares; see go.nature.com/31rcajd). Consequently, on a global scale, acidity is the most important soil constraint for agriculture4. However, there have been no detailed multi-regional analyses of the difference in crop yield between low-pH and optimum-pH soils, and such investigations would benefit the study of synergies between carbon-sequestration methods. The proposed rock additions could conceivably mitigate the low use and supply shortages of agricultural limestone in several regions5. Furthermore, calcium improves root growth in acidic subsurface soil6, with crucial knock-on effects through greater water uptake by plant roots.

    World's Largest Offshore Wind Farm To Power UK 'Gigastack' Green Hydrogen Facility
    https://www.intelligentliving.co/worlds-largest-offshore-wind-uk-gigastack-green-hydrogen/

    The largest offshore wind farm in the world – Ørsted’s 1.4GW Hornsea 2 – is almost ready. When it is, it will power the production of green hydrogen under a program called the “Gigastack” project, which was newly-awarded additional funding of £7.5m ($9.7m) by the UK government. Green hydrogen is seen as the ‘missing link’ in the energy transition. While it is growing in popularity, offshore wind is simultaneously emerging as a critical potential power source for producing it in bulk.

    Meanwhile, phase 2 of the Gigastack industrial-scale green H2 (hydrogen) facility is in the works. The project is a collaboration between Danish wind giant Ørsted, Element Energy, Phillips 66 Limited, and ITM Power, who will lead the undertaking. Their goal is to deliver zero-carbon hydrogen using ‘stackable’ 5MW electrolyzers – ones produced in gigawatt-scale factories for large-scale generation. The electrolyzers will “split” hydrogen from water via an electrical current supplied by offshore wind farms.

    ...

    The zero-carbon green hydrogen produced can be used for long-term energy storage and as a replacement for fossil fuels in transport, industrial processes, and heating. Clean hydrogen could help make the entire global energy system carbon-free.

    ...

    Industrial sectors, such as metal manufacturers, are beginning to explore the benefits of renewable hydrogen as an alternative fuel and power source. Gigastack could further accelerate that trend by bringing costs down on an industrial scale.



    Gigastack Feasibility Study with Ørsted
    https://www.itm-power.com/...hydrogen-through-gigawatt-scale-pem-electrolysis-manufactured-in-the-uk

    In Phase One (feasibility), ITM Power will develop the designs and finalise the material requirements to deliver a low-cost 5MW stack. ITM Power will also refine concepts to maximise the throughput of the proposed semi-automated manufacturing facility to meet the demands of bulk hydrogen supply. Ørsted will investigate potential synergies between offshore wind farms and electrolysers to identify scenarios that can provide affordable electricity and a sufficient load factor to allow economic operation of the electrolysers. Finally, Element Energy will conduct market analysis of potential end users, explore business models for the operation of large electrolysers in the energy system and define a roll-out strategy for the first 100MW electrolysers.

    In Phase Two, the 5MW stack would be built and tested both in-house and in a representative wind-hydrogen scenario. Construction of the semi-automated manufacturing facility would also begin. Finally, the business case for large electrolysers would be refined, enabling commercialisation.

    This project is a unique opportunity to develop green hydrogen production for the UK and establish the country as a centre of excellence in electrolytic technology. A portfolio of solutions are required to ensure reliable volumes of hydrogen and security of supply and this study will advance the development of green electrolytic hydrogen.
