    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?

    Elon Musk suggests AI satellites could dial down global warming
    https://interestingengineering.com/space/elon-musk-solar-radiation-management-geoengineering

    while Musk’s companies have unmatched reach in space infrastructure, scaling an SRM system to planetary levels is another story. “It would be far easier said than done,” as one analyst put it, especially given that even the most advanced SRM proposals remain largely theoretical.

    Beyond the science, there’s also geopolitics. Who decides when and how to shade the planet? And what happens if one nation’s cooling efforts trigger droughts in another?

    there’s no indication SpaceX is working on SRM-capable satellites. For now, the comment seems more like a thought experiment than a corporate roadmap.

    Yet Musk’s timing is telling. With heat records being broken year after year, and progress on emissions lagging, even the most radical climate ideas are starting to sound less far-fetched

    The 2025 state of the climate report: a planet on the brink
    We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the
    climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction,
    unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms,
    floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing.
    Key Highlights
    • The year 2024 set a new mean global surface temperature record, signaling an escalation of climate upheaval.

    • Currently, 22 of 34 planetary vital signs are at record levels.

    • Warming may be accelerating, likely driven by reduced aerosol cooling, strong cloud feedbacks, and a darkening planet.

    • The human enterprise is driving ecological overshoot. Population, livestock, meat consumption, and gross domestic
    product are all at record highs, with an additional approximately 1.3 million humans and 0.5 million ruminants added weekly.

    • In 2024, fossil fuel energy consumption hit a record high, with coal, oil, and gas all at peak levels. Combined solar and
    wind consumption also set a new record but was 31 times lower than fossil fuel energy consumption.

    • So far, in 2025, atmospheric carbon dioxide is at a record level, likely worsened by a sudden drop in land carbon uptake
    partly due to El Niño and intense forest fires.

    • Global fire-related tree cover loss reached an all-time high, with fires in tropical primary forest up 370% over 2023,
    fueling rising emissions and biodiversity loss.

    • Ocean heat content reached a record high, contributing to the largest coral bleaching event ever recorded,
    affecting 84% of reef area.

    • So far, in 2025, Greenland and Antarctic ice mass are at record lows. The Greenland and West Antarctic ice sheets
    may be passing tipping points, potentially committing the planet to meters of sea-level rise.

    • Deadly and costly disasters surged, with Texas flooding killing at least 135 people, the California wildfires alone
    exceeding US$250 billion in damages, and climate-linked disasters since 2000 globally reaching more than US$18 trillion.

    • Climate change is endangering thousands of wild animal species; more than 3500 species are now at risk and
    there is new evidence of climate-related animal population collapses.

    • The Atlantic meridional overturning circulation is weakening, threatening major climate disruptions.

    • Climate change is already affecting water quality and availability, undermining agricultural productivity, sustainable
    water management, and increasing the risk of water-related conflict.

    • A dangerous hothouse Earth trajectory may now be more likely due to accelerated warming, self-reinforcing
    feedbacks, and tipping points.

    • Climate change mitigation strategies are available, cost effective, and urgently needed. From forest protection
    and renewables to plant-rich diets, we can still limit warming if we act boldly and quickly.

    • Social tipping points can drive rapid change. Even small, sustained nonviolent movements can shift public
    norms and policy, highlighting a vital path forward amid political gridlock and ecological crisis.

    • There is a need for systems change that links individual technical approaches with broader societal
    transformation, governance, policies, and social movements.

    Scientists have uncovered that glaciers can temporarily cool the air around them, delaying some effects of global warming. This self-cooling, driven by katabatic winds, is nearing its peak and will likely reverse in the next two decades. Once glaciers lose enough mass, they will heat up faster, speeding their decline. The team urges immediate global action to curb emissions and manage dwindling water resources wisely.

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.

    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."

    One of the most severe marine heatwaves on the planet is taking place in the shallow seas around the UK and Ireland. That’s according to the US National Oceanic and Atmospheric Administration (NOAA), which has labelled this a “Category 4” heatwave. Rarely used outside of the tropics, a cat 4 heatwave means “extreme” heat.

    Marine heatwaves are classified as “prolonged periods of anomalously high sea surface temperature”, when compared to the long-term average for that time of year. And thanks to measurements made by satellites orbiting the earth we know that, in some areas around the UK, surface water temperatures are 4°C to 5°C above normal for mid June.

    This is extremely unusual: buoys around Ireland and the UK have been recording sea surface temperature for over 20 years, and in that time it has never been this hot this early in the summer.
    ...
    At this time of year, these plankton are dependent on nutrients mixed up from the deep water into the surface layer. However, this year, this nutrient supply may be diminished, since the very high surface temperature means there is likely stronger stratification and less mixing.

    A heatwave on the surface could potentially harm the deeper ocean too, and the fish that live there. These continental shelf seas are already suffering from a decline in deep water oxygen, which is partly offset by mixing oxygen-rich water from the surface. However, the fact that the surface temperatures are so high point to a lack of mixing between the layers, and in any case, warmer water contains less oxygen.
