    "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.

    Jinak před pár dny vyšla publikace EAT-Lancet, na téma zdravých, udržitelných a spravedlivých potravinových systémů. Jedním z autorů je Johan Rockström a obecně pracuje s daty Planetárních mezí.

    Even if the entire world transitions away from fossil fuels, the way we farm and eat will cause global temperatures to rise 1.5 degrees Celsius above preindustrial levels.

    The new report builds on the commission’s first report, published in 2019 — an enormous undertaking that examined how to meet the nutritional needs of a growing global population while staying within planetary boundaries. It was highly influential and widely cited in both policy and academic literature, but it was also ruthlessly attacked in an intensive smear campaign by meat industry-aligned groups, academics, and influencers — a form of “mis- and disinformation and denialism on climate science.”

    “The diets of the richest 30% of the global population contribute to more than 70% of the environmental pressures from food systems,” the new report reads.

    If globally adopted, this plant-rich diet would prevent up to 15 million premature deaths each year.

    Assessment of the ecological and environmental effects of large-scale photovoltaic development in desert areas | Scientific Reports
    https://www.nature.com/articles/s41598-024-72860-8

    Photovoltaic development has played a crucial role in mitigating the energy crisis and addressing global climate change. However, it has also had significant impacts on the ecological environment. To ensure the sustainable growth of the photovoltaic industry, it is essential to establish an indicator system to assess the ecological and environmental effects of photovoltaic development. This study utilizes the Driving-Pressure–Status–Impact-Response (DPSIR) framework to create an indicator system for evaluating the ecological and environmental effects of desert photovoltaic development. The study evaluates the ecological and environmental effects at the on-site (WPS), transitional zone (TPS), and off-site (OPS) areas of the Qinghai Gonghe Photovoltaic Park in China. The entropy weight method was utilized to calculate indicator weights, while the evaluation model and indicators were transformed uniformly to obtain standardized scores for ecological and environmental effects. and conducting a thorough analysis of the distribution characteristics and factors influencing the evaluation indicators’ scores. Overall, the large-scale development of desert photovoltaics in Gonghe County has had a positive impact on the ecological environment. The WPS had better ecological and environmental conditions than did the TPS and OPS, and the ecological and environmental evaluation levels of the WPS were categorized as “general” (0.439), while the ecological and environmental effect evaluation levels of the TPS (0.286) and OPS (0.28) were both “poor”, indicating significant room for improvement. Moreover, all indicators in the scheme layer, which are used to evaluate ecological and environmental quality, yielded higher scores for the WPS than for the TPS and OPS, demonstrating that photovoltaic development has a positive effect on desert area ecology and the environment.

    UN plastics treaty chair to step down with process in turmoil | Plastics | The Guardian
    https://www.theguardian.com/environment/2025/oct/07/un-plastics-treaty-chair-to-step-down-with-process-in-turmoil

    In August, global talks at the UN headquarters in Geneva to agree on a treaty to deal with accelerating plastic pollution collapsed after three years of negotiations. There is currently no deal and the future of the agreement is unclear.

    The chair’s sudden resignation leaves the plastic treaty in an even more uncertain position, and raises questions around the governance of the process.

    Vayas Valdivieso faced criticism from NGOs and member states during the latest stage of the talks for releasing a draft text, which was rejected by the majority of negotiators and described by the UK’s head of delegation, the minister Emma Hardy as the “lowest common denominator”. Ghana said the text would “entrench the status quo for decades to come”.

    XCHAOS: Životnost něco mezi 1000-3000 let no, a GWP (global warming potential) v řádu 100 let 23500, v řádu 500 let 32600.. horší je snad možná jen CF4 (Tetrafluoromethan) nebo C2F6 (Hexafluoroethan) a to kvůli mnohem delší životnosti. Zatím je pouze návrh o jeho zákazu, ale to zatím myslím není odsouhlaseno a jednalo by se stejně jen o EU.

    Nějaké cesty jak s tím nakládat jsou, ale žádná sláva, takže je to zatím spíše o tom zabránit úniku a bezpečně uložit, to bezpečně je dle mého pochybné, podobně jako s jaderným odpadem.
    Disposal methods, health effects and emission regulations for sulfur hexafluoride and its by-products
    https://www.sciencedirect.com/science/article/abs/pii/S0304389421010712
    The SF6 gas alone has no immediate impact on the environment due to its inert nature. Despite that, the staggering global warming potential it has can cause a serious problem in the long run. It is a greenhouse gas that accumulates in the atmosphere which captures the heat released from the earth’s surface and reflects it.

    The disposal methods for SF6 involves the complete decomposition of the gas which is categorized into the conventional and advanced approaches. Incineration is the most common conventional method being practiced. The issues associated with cost and toxic by-products formation sparked the search and development for alternative technologies such as NTP.

    Based on the literature as a whole, the only issues that are hindering the NTP techniques from maturing are the combination of power supply, additive gases, flowrates, concentrations and length of reactor that will result in the highest possible decomposition efficiency of SF6 and the removal of its toxic counterparts from being released to the environment. The experiments mainly focus on small-scale plasma systems that utilize very small volumes and flowrates.


    Sulfur Hexafluoride (SF6) Basics
    https://www.epa.gov/eps-partnership/sulfur-hexafluoride-sf6-basics
    The most common use for and largest emission source of SF6, both domestically and internationally, is as an electrical insulator in high-voltage equipment that transmits and distributes electricity. Approximately 67% of all SF6 emissions in the United States is attributed to the electrical transmission and distribution sector in 2022 based on the Inventory of U.S. Greenhouse Gas Emissions and Sinks.

    SF6-containing equipment is designed to avoid emitting any of this gas into the atmosphere. However, SF6 gas can inadvertently escape as leaks develop during various stages of the equipment's lifecycle, including manufacturing, installation, maintenance and servicing, and de-commissioning. In some cases, significant leaks can occur from aging equipment.

    Several factors affect SF6 emissions from electric power systems, such as the type and age of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities.

    The Trump administration has announced sweeping measures to expand coal production on public lands. It intends to open 13.1 million acres of public land for coal leasing, significantly loosen the royalty rates that mining companies pay, and allocate large sums toward existing coal-fired power plants. A central component of the plan is to dismantle or weaken dozens of environmental regulations that restrict pollution from coal operations and power plants.

    The Trump administration’s coal plan does not stop at opening millions of acres of public land or reducing royalties. It is paired with an unprecedented wave of environmental deregulation that collectively weakens protections for air, water, and climate. Rules that once limited carbon emissions from power plants, such as the Clean Power Plan and its successors, have been repealed or replaced with far weaker standards, allowing utilities to emit far more greenhouse gases at a time when global climate goals demand steep reductions.

    Mercury and Air Toxics Standards, designed to curb neurotoxic pollution that damages brain development and causes respiratory illness, have been scaled back, with nearly seventy coal plants granted exemptions from compliance. Similarly, the administration has rolled back limits on particulate matter, sulfur dioxide, and nitrogen oxides (pollutants linked directly to asthma, heart disease, and premature deaths) while loosening oversight of methane emissions, a potent greenhouse gas.

    Water protections have also been eroded. The Stream Protection Rule, which restricted coal companies from dumping mining waste into rivers and streams, was repealed, increasing the risk of heavy metals and toxins entering drinking water sources. Wastewater and coal ash standards for power plants have been relaxed, enabling greater discharge of arsenic, selenium, and other contaminants into waterways. By narrowing the scope of the Clean Water Act, fewer wetlands and tributaries now receive federal protection, leaving them vulnerable to pollution.

    Collectively, these changes lower costs for coal operators but shift the burden onto communities, which face higher health risks from toxic air and water, degraded ecosystems, and accelerating climate change.

    Trumpuv projev v OSN hodinu zpět byl výběr z hroznů:

    "The 'carbon footprint' is a hoax made up by people with evil intentions, and they're heading down a path of total destruction."

    "Europe loses more than 175,000 to heat deaths every year because the costs are so expensive you can't turn on an air conditioner. What is that all about? That's not Europe. That's not the Europe that I love and know. All in the name of pretending to stop the global warming hoax."

    Preventing 2°C by 2040 | Act Now for Climate Action
    https://www.preventing2degrees.org/

    the Paris Accord’s critical red line of 2°C is likely to be breached by 2037—just 12 years from now.

    We are nearly out of time to avert 2°C. But, there are tools in the toolbox that can buy more time to successfully stop global heating in the short term, while we strive to bring down emissions in the medium to long term.

    Over two days, we will host five hours of discussion that will address:

    Why is global heating now accelerating so much faster than before?

    What are the consequences to people and the planet if we fail to act immediately?

    How can we stop temperatures from rising and avert catastrophic heating: What’s the plan?

    What immediate, practical steps can we take to develop and implement a new, integrated climate plan for humanity?

    bylo ze carbon storage asi nepujde?

    A study led by researchers from NASA found that the world doesn’t have remotely enough safe places to store carbon dioxide to realize some of humanity’s more ambitious carbon capture plans. These plans typically assume that carbon dioxide, once captured, would be pumped under pressure underground into suitable rocks and sealed there. But finding rock formations where the carbon dioxide does not leak back out isn’t all that easy. The researchers also excluded any locations nearby human settlements due to the risk inherent in such storage, and any locations that would make storage too costly. They conclude that the places left could effectively reduce global warming by about 0.7°C if fully used – far less than the 5-6°C assumed to be possible in some scenarios (especially those favored by the fossil fuel industry).

    While it’s good to quantify the problem, I think these numbers are redundant because the technology to remove carbon from the atmosphere (or even capture it effectively at fossil fuel power plants) is currently so inefficient and costly it won’t make any difference for global warming, certainly not in the near future, and quite possibly not ever. Press release here. Paper here.

    “New research explores climate change and the limits of human progress…

    "The deeper problem, he argues, lies in the complexity of civilization itself—a global industrial society that has grown both unsustainably expensive and dangerously vulnerable to the environmental stresses that accompany climate change."

    "A lot of people confuse pessimism with nihilism, apathy and despair," Scranton said. "But pessimism is actually about recognizing our limits, letting go of unrealistic goals, finding solidarity in the fact of human suffering and doing what you can now, not in some utopian future."

    "Modern pessimism emerged as a skeptical critique of early Enlightenment hubris, but it has roots in ancient wisdom from Sophocles to the Bhagavad Gita. Both the history of philosophy and modern insights from psychology show that pessimism is not only an effective way to deal with big problems, but a healthy approach to the unpredictability of circumstance, especially in fraught and difficult times."

    In "Impasse," Scranton examines the "myth of progress"—how cultures have navigated societal collapse, failures in climate change communication, political extremism and "the end of the world as we know it"—ultimately concluding that the situation does not seem to be comprehensible within progressive modernity.

    "Pessimism is fundamentally about recognizing and living within natural human limits,” Scranton writes. “It’s about recognizing that suffering is inevitable but not unbearable. It’s about learning to die and learning to live with death. And finally, it’s about committing to a radical and paradoxical hope: the hope that life might be worth living after the end of the world."

    ACCELERATING SEA LEVEL RISE & 2024 JUMP

    Acceleration of sea level rise is unquesionable
    NASA said a jump in 2024 was unexpected.
    Loss of ice from Greenland and Antarctica is increasing, and ice loss from mountain glaciers is accelerating- which has major effect on se level. Most of the sea level rise is actually now from land ice melt. It's a good indicator of the power of global warming.

    A method to identify positive tipping points to accelerate low-carbon transitions and actions to trigger them | Sustainability Science
    https://link.springer.com/article/10.1007/s11625-025-01704-9

    Meeting the Paris Agreement to limit global warming to “well below 2 °C” requires a radical acceleration of action, as the global economy is decarbonising at least five times too slowly. Tipping points, where low-carbon transitions become self-propelling, could be key to achieving the necessary acceleration. We deem these normatively ‘positive’, because they can limit considerable, inequitable harms from global warming and help achieve sustainability. Some positive tipping points, such as the UK’s elimination of coal power, have already been reached at national and sectoral scales. The challenge now is to credibly identify further potential positive tipping points, and the actions that can bring them forward, whilst avoiding wishful thinking about their existence, or oversimplification of their nature, drivers, and impacts. Hence, we propose a methodology for identifying potential positive tipping points, assessing their proximity, identifying the factors that can influence them, and the actions that can trigger them. Building on relevant research, this ‘identifying positive tipping points’ (IPTiP) methodology aims to establish a common framework that we invite fellow researchers to help refine, and practitioners to apply. To that end, we offer suggestions for further work to improve it and make it more applicable.
