    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.

    porovnavat tepelnou energii paliv co potrebujou kyslik (tzn vaha spalovane smesi je pak uplne jina) s elektrickou energii v baterkach a dokonce s energii jakou doakze metabolismus dostat z bagety .. to je proste uplne mimo

    Polish oil firm signs up to 2050 climate neutrality goal – EURACTIV.com
    https://www.euractiv.com/...vironment/news/polish-oil-firm-signs-up-to-2050-climate-neutrality-goal/

    PKN Orlen, Poland’s largest oil refiner and retailer, this week became the first oil company in central Europe to commit to climate neutrality by 2050, with plans to invest billions in energy efficiency, solar, wind, and hydrogen.

    Orlen vlastni Benzinu - nejvetsi sit pump v Cesku. Polaci fakt jedou - spocetli si dobre, ze nema smysl jit proti zbytku EU, ale ze je lepsi to vzit jako prilezitost, jak uspet na nove se formujicim trhu s cistou energii.

    Za me super, protoze Cesi se radi nad Polaky povysuji, ale pokud pujde vse dal tak, jak je ted, tak brzy bude fakt tezke v Cesku obhajovat to, ze zatimco jim se dari, nam zbyvaji jen zastarale ideologicke floskule...

    Cattle Are Part of the Climate Solution - Rodale Institute
    https://rodaleinstitute.org/blog/cattle-are-part-of-the-climate-solution/

    Rodale Institute interviews Savory science advisor Dr. Richard Teague:
    “Prior to starting our regenerative grazing studies in 1999, we worked with the NRCS who did all the soil mapping around the nation. We asked them to introduce us to farmers and ranchers who had the highest soil carbon levels. Without a single exception, they were all following Holistic Management, or a couple of variations around that.”

    Six Portuguese youth file 'unprecedented' climate lawsuit against 33 countries
    https://www.climatechangenews.com/...rtuguese-youth-file-unprecedented-climate-lawsuit-33-countries/

    Six Portuguese young people have filed a legal action accusing 33 countries of violating their right to life by not doing their fair share to tackle the climate crisis.

    This is the first climate change case to be filed with the European Court of Human Rights (ECHR) in Strasbourg, France. If admissible, it could set an important precedent, showing the way for other climate lawsuits based on human rights arguments.

    Klimatické závazky ČR – Klimatická žaloba ČR
    https://www.klimazaloba.cz/klimaticke-zavazky-cr/


    Úvodní stránka – Klimatická žaloba ČR
    https://www.klimazaloba.cz/

    Klimatická žaloba ČR je žaloba na české státní orgány odpovědné za snižování emisí a adaptační opatření na změnu klimatu, která bude podána k českým soudům. Žaloba, jejíž znění připravuje advokátní kancelář Frank Bold Advokáti, bude podána spolkem českých občanů, kteří se cítí být ohroženi nečinností státních orgánů v předcházení změně klimatu. Cílem žaloby je soudní výrok stanovující, že české státní orgány nechrání dostatečně práva českých občanů zaručená Ústavou a neplní své mezinárodní závazky ve vztahu ke změně klimatu.

    SHEFIK: odkud to je? pokud chce nekdo porovnavat baterky s palivem, tak by bylo fer zapocist ucinnost motoru a generatoru. proste porovnavat elektrinu s elektrinou a ne hrusky s jabkama.

    XCHAOS: mohl bys svoje tvrzeni nejak podlozit? protoze je to opak toho, co ctu...

    co se tyka platiny, to je o technologii
    https://phys.org/news/2020-05-platinum-free-catalysts-cheaper-hydrogen-fuel.html

    co se tyka objemu, ja nechci v patek v noci delat chemickou resersi, ale kdyz mas sportaka na 1600km ve vodiku, kterej jezdi 355km
    https://evcentral.com.au/hyperion-xp-1-355km-h-1600km-hydrogen-hypercar-revealed/

    a o chlup vetsi teslu na baterky s dojezdem 500km a omezovacem rychlosti, protoze by se baterie vyjela za 100km na plnej plyn, tak to neco vypovida o hustote energie a jejim skladovani.

    je potreba si uvedomit, ze jsme sice vodik pouzivali uz pred 100 lety, ale tehda nebyl internet (vic hlav vzdycky vic vi), startup incubatory, klimaticka krize, levna ropa a tak obrovskej objem investic do alternativ. u vodiku jsme teprve na zacatku cesty...

    taky se nesmis fixovat jen na elektrolyzu, ale treba vodik misto skladkovani:

    ...a i elektrolyza pujde dopredu
    https://cordis.europa.eu/article/id/421850-making-green-hydrogen-more-affordable

    The CHANNEL (Development of the most Cost-efficient Hydrogen production unit based on AnioN exchange membrane ELectrolysis) project will run until December 2022. It aims to develop a low-cost and efficient electrolyser unit utilising “non-PGM electrocatalysts, porous transport layers, current collectors, bi-polar plates, state-of-the-art anion exchange membranes and ionomers,” as noted on the project website. “This will enable the development of an electrolyser technology at a capital cost (CAPEX) equal or below classical alkaline electrolysis. However, in contrast to the alkaline technology, the CHANNEL AEM electrolyser will have an efficiency and current density operation close to the one of proton exchange membrane electrolyser (PEMWE).” The project website also states: “The CHANNEL stack will not only result in decreased electrolyser part count, but it will also be able to operate at differential pressure, as well as under dynamic operation, optimal for producing high quality, low cost hydrogen from renewable energy sources.”

    The science of orange wildfire skies
    Another year of record wildfires in the western United States has turned the skies orange over cities such as San Francisco, California. The effect is down to more than just smoke blocking the Sun. Trapped by a layer of fog that lingers over the cool ocean, soot particles from the fires refract different wavelengths of light from clear air. With red and orange wavelengths dominating the view — no more blue skies.

    Huge decline in abundance of life on Earth
    Wildlife populations plunged by 68% between 1970 and 2016, and only 25% of the planet can still be considered ‘wilderness’. The grim numbers come from a report by wildlife charity WWF and the Zoological Society of London (ZSL), based on global data on 20,811 populations of 4,392 vertebrate species. Worst hit is Latin America and the Caribbean, where the animal population dropped by an average of 94% during that period. Food production is the biggest driver of nature loss, says the report, with about half of the world’s habitable land area already used for agriculture. “We are wrecking our world — the one place we call home — risking our health, security and survival here on Earth,” says WWF chief executive Tanya Steele.
