    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.

    Ethereum’s “Merge” is about to put every ether miner out of work | Ars Technica
    https://arstechnica.com/tech-policy/2022/08/the-merge-the-biggest-change-in-ethereum-history-explained/

    Digiconomist estimates that Ethereum miners currently consume 44.49 TWh per year which works out to 5.13 gigawatt on a continuing basis. This means that PoS is ~2000x more energy efficient based on the conservative estimates above, which reflects a reduction of at least 99.95% in total energy use.

    ...

    Recent estimates suggest that will happen sometime between around September 15 and September 19, but the exact date depends on how much computing power miners bring to bear over the next month.

    Norway has supported Sweden in proposing measures against mining Bitcoin and other cryptocurrencies. The reason for the growing concern is serious environmental degradation, which could turn into a catastrophe if energy consumption is not controlled.

    ...

    For many crypto miners, Norway has become a true paradise. The local authorities actively use renewable energy sources and charge a reasonable fee for electricity. A huge number of hydroelectric power plants have been put into operation in the country.

    Sweden calls for crypto mining ban to protect the climate

    The renewable drive
    In the letter, Swedish government directors said crypto-producers are now turning their attention to Nordic countries, as taxes for mining-related activities are favorable and there’s good access to cheaper renewable energy. In Sweden, electricity consumption for Bitcoin mining now accounts to 1 TWh annually, which equals to electricity 200,000 Swedish households.

    Bill Gates Sounds Alarm On Bitcoin's Energy Consumption–Here's Why Crypto Is Bad For Climate Change
    https://www.forbes.com/...ciano/2021/03/09/bill-gates-bitcoin-crypto-climate-change/?sh=427574206822

    "Bitcoin uses more electricity per transaction than any other method known to mankind,” Gates told the New York Times in a recent interview, calling himself a "bitcoin skeptic," and adding that "it’s not a great climate thing.”

    To Gates' point, Alex de Vries, a data scientist at the Dutch Central Bank, estimates that each bitcoin transaction requires an average 300 kg of carbon dioxide (CO2)–equivalent to the carbon footprint produced by roughly 750,000 Visa swipes.
