    TUHOKlimaticka zmena / Destroying the Future Is the Most Cost-Effective


    "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 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."

    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.

    TADEAS: aneb naznaky klimatickeho povstani, pro mainstream levicova anarchie.


    We can no longer afford the rich.
    We can initiate the end of the imperial lifestyle.
    We can stop the plundering of the Earth.
    In the greed for energy, the Earth is being drained, sucked dry, burned, abused, razed, raped, and destroyed. Entire regions are rendered uninhabitable by the heat. They simply burn up. Or habitats disappear beneath the waves during floods or due to rising sea levels.
    Shutting down fossil fuel power plants is a task that can be accomplished by hand. Have courage.
    We know we must interrupt this destruction. We know we are not alone. Don't give up hope for a world where life has space, not the greed for money, power, and destruction.

    ...

    Last year, the CO₂ concentration in the atmosphere rose to 423.9 parts per million, a value that surpasses all previous records. At the same time, climate scientists agree that the massive transatlantic ocean currents will collapse sooner or later due to global warming. This collapse of ocean currents, which has so far afforded the North a mild climate, is only one part of the catastrophe that awaits us. The extent of this devastation is simply ignored, abstracted, and discussed at global climate conferences until the scale of the destruction disappears into tables and declarations of intent.
    But the insatiable hunger for energy is eating its way through the Earth's crust and our lives, among other things to feed artificial intelligence, which then spouts stereotypes and absurdities, confusing, disorienting, and/or manipulating us. Meanwhile, with each new "learning" of the AI ​​using previous data, language, expression, and vitality are increasingly reduced, mutilated, and limited.

    ...

    We don't claim to know the way out. But we do know we must stop this destruction. Hedonism can no longer hold us captive once we've tasted the sweat of fear that spreads when there's no way out. No going forward, no going back. Only the horror of where we, as humanity, have ended up. When the question falls back on us, what did you actually do to prevent what was coming? You saw it coming, the survivors, the next generations, ask us. Please don't bring up the political parties. Please don't bring up the brown-shirted alternatives in pinstriped suits and dresses. And not the Greens or the Left either. Don't bring up the economy, whose free market will supposedly solve the problem. Economics and politics deal with death every day. With dictatorships and butchers. Their concerns vanish into thin air when it comes to satisfying our energy needs, for example. Russia is still supplying gas to Europe via Nord Stream 1. And the US wants Venezuela's oil. That's why military attacks are now taking place. And fracked gas arrives by ship from all over the world. Currently, 79% comes from the USA! Fracking is extremely environmentally damaging in its production. Even during extraction, a methane loss of 6 to 10 percent is assumed, which further warms the atmosphere.

    95% of the gas burned in Germany is imported. At climate summits, only tactical lip service is forthcoming because the oil-producing countries are not interested in climate protection but in money. Because the major cities base their policies on money and growth, lobbyists in Europe are being handed the end of the combustion engine phase-out.

    For example, the German Minister of Economic Affairs, Katharina Reiche, was State Secretary in the Federal Ministry of Transport, a lobbyist for the Association of Municipal Enterprises (VKM), and a manager at the E.ON subsidiary Westenergie. Minister Reiche presents herself as a supporter of hydrogen but primarily relies on natural gas. She intends to issue tenders for additional gas-fired power plants with a capacity of 10 gigawatts, which are to be connected to the grid by 2031, corresponding to approximately 25 new power plants. 20 billion euros are earmarked for these new gas-fired power plants.

    Reiche would prefer to postpone Germany's climate neutrality target from 2045 to 2050 anyway.

    The main culprits behind human-induced climate destruction are not those who suffer the most, those who pay with their health and their lives. The people of the Global South are already paying the highest price. The countries of the Global North, and soon China among others, are deciding the fate of everyone. China, as a communist, racist, and patriarchal dictatorship, can use "rare earth elements" to blackmail countries that don't toe the line, gradually weaving countries, cultures, and political systems into the cocoon of this new dictatorial world power. Over 85% of the world's refined "rare earth elements" come from China. And it is the rich who are the problem. It is the super-rich who are setting the world ablaze. In the East, in the West, in the South, and in the North. Sixty percent of the super-rich's investments worldwide go into gas and oil. And around 300 super-rich countries emit more CO₂ than the 110 poorest countries in the world. These criminals know it. They don't care. Their greed for even more wealth and power sets the standard by which everyone else follows

    China doesn’t want to lead alone on climate policies, senior adviser warns | Cop30 | The Guardian
    https://www.theguardian.com/environment/2025/nov/19/china-doesnt-want-to-take-lead-on-climate-policies-alone-senior-adviser-warns

    In an exclusive interview, Wang said theChinese president, Xi Jinping, was committed to the energy transition for the long haul despite resistance from some industrial sectors. He explained that China’s priority in Belém was to help the Brazilian presidency achieve a successful climate conference, and to show the benefits of multilateral decision-making. On Tuesday, the first draft of a possible agreement was published at the Cop30 summit, reviving the hotly contested plan to transition away from fossil fuels.

    China is the planet’s biggest emitter of carbon dioxide from burning of coal, oil and gas, but it is now also a world leader in the production, installation and export of wind turbines, solar panels and electric cars.

    He said China wanted to “speed up and scale up its efforts to provide more global public goods” despite serious geopolitical and economic tensions and unilateral barriers to trade, including tariffs. The country’s emissions have been flat or falling for 18 months.

    He estimated China’s per capita power consumption would continue to grow from 7,000 kilowatt hours in 2024 to “well over 10,000, maybe 12,000” – but there would be a steady move away from fossil fuels to wind and solar, as well as green hydrogen, green ammonia and electric vehicles. Along with a new power grid system, he said the country was in the midst of a “comprehensive green transition of social economic development”.

    As in many countries, Wang suggested there was some resistance to change, but the president had sent a clear signal about the direction of travel. “Even in China, we have a lot of industrial conflict ... but the central government, including President Xi, is very clear to us that we must, in the next five years’ time, speed up the new power system.”

    In the absence of the US, China’s role is even more crucial than usual to the success or failure of Cop30, where the Brazilian president, Luiz Inácio Lula da Silva, has urged his negotiators to lay the foundations for an exit ramp out of the fossil fuel era.

    Climate startups button up for a post-election freeze
    https://pitchbook.com/news/articles/climate-startups-election-trump-inflation-reduction-act

    For the climate tech startups now navigating this stage, it’s going to be a rough six months. As the industry adjusts to a new energy policy regime under President-elect Donald Trump, there’ll be a chill in the air for project financing and major fundraising for companies in the line of fire.

    Potentially on the chopping block are key provisions of the US Inflation Reduction Act, the budget of the Department of Energy and Treasury guidelines on tax credits. Offshore wind and hydrogen projects are two areas that are thought by VCs to be especially precarious.

    And despite Trump’s cozy relationship with Tesla founder Elon Musk, the transition team is already planning to scrap a $7,500 EV tax credit for American consumers, according to Reuters.

    “It’s going to be challenging,” said Abe Yokell, managing partner at Congruent Ventures. “My general advice is, make sure you aren’t raising right now.”

    ...

    In the eight years since Trump’s first victory, early-stage investing in climate tech has become mainstream, as specialists like Breakthrough Energy Ventures and Lowercarbon Capital made their names on Sand Hill Road, bringing generalists along with them into climate rounds.

    Huge amounts of capital have flowed into infrastructure funds dedicated to the energy transition, driven by pressure from pension holders and students as well as a belief that the energy transition is a lucrative investment.

    “Most new infrastructure is clean infrastructure now,” said Yokell. Energy transition infrastructure funds raised $33.5 billion in 2024, compared to $9.5 billion for non-energy transition infrastructure funds, according to PitchBook research.

    Institutional investors think in decades, not in single election cycles.

    Plus, much of the climate policy cemented by the Biden administration has bipartisan support: namely, creating more resilient supply chains, nearshoring critical minerals production and creating clean-energy jobs in battleground states.

    Trump’s calls to deregulate and reduce permitting roadblocks may help clean energy projects in the long run, especially for new nuclear technologies that have been bogged down in red tape.

    For Yokell, there’s a strong case to stay bullish on climate-friendly projects:

    “There will be some collateral damage environmentally, which I’m not excited about, but the lack of regulations will in fact allow for a lot of clean infrastructure to be built.”

    Německo schválilo plány na výstavbu vodíkové sítě za přibližně 19 miliard eur, v přepočtu zhruba 459 miliard korun. Návrhy tamních provozovatelů přenosových soustav počítají s tím, že vodíková síť bude kompletně zprovozněna už do roku 2032. Projekt má zemi pomoci s dosažením klimatické neutrality do roku 2045.

    Délka německé vodíkové sítě má dosahovat na 9 040 kilometrů a očekává se, že bude plně funkční již do osmi let. Má propojit i klíčová průmyslová centra včetně důležitých výrobců oceli, kteří v posledních letech pracují na dekarbonizaci své výroby, píše agentura Bloomberg.

    VOYTEX:
    Asi jsem nedočetl dostatečně daleko, abych pochopil o čem přesně diskuze je, nicméně zde je nějaké info o vodíku:

    V průmyslu má mnohem důležitější využití než jako úložník energie, a nemáme za něj náhradu.

    99% vodíku je momentálně získáváno z fosilních paliv, pokud bychom měli vyrábět zelený/žlutý vodík, měli bychom hlavně nahrazovat momentální produkci, samotná výroba vodíku má momentálně na svědomí více emisí než letecká doprava

    Vodík také nepřímo ovlivňuje oteplování, vezměme v o jak lehký prvek se jedná, úniky jsou něco co se dá očekávat, skladování je tragédie.

    Často se mluví o průmyslovém využití, ale snad až na ocelářství není moc případů, kde by se to vyplatilo oproti přímému použití elektřiny, vzhledem k tomu, že se mluví hlavně o náhradě zemního plynu, který se používá na ohřev vody. Takže bychom možná našli hrstku průmyslů kde by to mělo nějaký význam, ale opět co nejdříve nahradit ten černý vodík.

    Mám pocit, že toto je (stejně jako další technologické naděje) hlavně hype, který se snaží nabalit investory a nic víc.

    Něco víc o vodíku -

    Czech steel industry unprepared for EU decarbonisation – Euractiv
    https://www.euractiv.com/section/politics/news/czech-steel-industry-unprepared-for-eu-decarbonisation/

    The Czech steel industry is unprepared for decarbonisation, not only technologically but also financially, making it difficult to implement the EU’s decarbonisation plans, experts say.

    Experts polled by the Czech News Agency (CTK), also agreed that the state lacks green electricity, hydrogen and other resources – all elements necessary to meet EU plans to be carbon neutral and effectively achieve net-zero greenhouse gas emissions by 2050.

    There are options for low-emission steel production, including replacing coke with hydrogen as a reducing agent or making steel from scrap in an electric arc furnace.

    However, there is not enough scrap to meet all demand. The production process requires large amounts of electricity, the price of which has risen enormously in recent years, Daniel Urban, chairman of the Czech Steel Union, told CTK.

    Octopus Project Combines Direct Air Capture With Water Recovery
    https://cleantechnica.com/2024/01/16/direct-air-capture-water-treatment-octopus-project-korea/

    Capture6 provides a money-saving workaround by linking its technology with water treatment systems. They kindly emailed some additional technical details to CleanTechnica that clarify the difference.

    “The process involves splitting salt in brine waste through electrochemical processes, producing a base and an acid,” they explain. “The base absorbs CO2 from the air, forming carbonates for long-term storage.”

    That’s not quite the same thing as carbonite, but the basic idea is the same. Carbonates are the main ingredient in solid materials like seashells and limestone. Once locked into a carbonate, the airborne carbon can be put to use instead of being shunted underground.

    Among the money-saving features noted by Capture6, the process conserves water resources by producing fresh water from wastewater. In addition to a potential revenue stream from that source, the system also harvests valuable chemicals including lithium, hydrogen, and hydrochloric acid, which is the stuff in your stomach that dissolves food.

    Europe could become energy self-sufficient in $2 trillion push, study says | Reuters
    https://www.reuters.com/markets/europe/europe-could-become-energy-self-sufficient-2-trillion-push-study-2023-10-04/

    The report, led by the Potsdam Institute for Climate Impact Research, said the continent would require annual investments of 140 billion euros by 2030 and 100 billion a year in the decade thereafter to get there.

    While most of the sum would be needed for onshore wind expansion, solar, hydrogen and geothermal resources would be additional pillars of a strategy that would enable Europe's electricity needs to be powered exclusively from renewables by 2030.

    It would take another decade to convert the entire energy system, including things such as heating currently powered by oil or gas, to renewables, according to the study, which was shared with Reuters.
