    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.

    Surrey team developing direct-air-capture CO2 to methanol process - Green Car Congress
    https://www.greencarcongress.com/2022/04/20220404-surrey.html

    Researchers at the University of Surrey (UK) are developing a process to capture carbon dioxide directly from the air and then use dynamic catalysis to create methanol—a valuable chemical that, made this way, could be carbon-negative. Its value could offset the cost of direct air capture.

    New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency - Green Car Congress
    https://www.greencarcongress.com/2021/11/20211116-electrocat.html

    The electrocatalytic conversion of CO2 using renewable energy could establish a climate-neutral, artificial carbon cycle. Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO2. These could then be burned as needed. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport.

    Now, researchers in China have developed a new electrocatalyst that yields ethanol, acetone, and n-butanol as major products with a total C2-4 faradaic efficiency of about 49 % at −0.8 V vs. reversible hydrogen electrode (RHE), which can be maintained for at least 3 months. A paper on the development is published in the journal Angewandte Chemie.

    Pro ccs/storage je pak spousta dalsich moznosti, i kdyz skladovani bez dalsiho vyuziti bude vzdycky neco stat. Rentabilnich ccs bude nejspis vzdycky malo, ale budou, viz napr. umely diamanty
