    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.

    Pardon za délku, líbilo se mi na redditu, ještě jsem výrazně zkrátila :)

    hyperobjects are a concept introduced by philosopher timothy morton to describe things so vast in scale, duration, or interconnectedness, existing through such vast expanses of space *and* time that they transcend the biological capabilities of human perception and comprehension. they are objects or phenomena that we interact with but cannot fully grasp due to their inherent complexity and distributed nature. hyperobjects include things like climate change, radioactive materials, global capitalism, or even the internet.

    hyperobjects exist on such expansive spatial and temporal scales that they are quite literally everywhere and nowhere all at once. for example, you can experience the effects of climate change (like extreme weather), but you can never point to a single, tangible "climate change" because it is dispersed across the entire globe and throughout time. hyperobjects persist over timeframes that dwarf human lifespans. radioactive waste and climate change remain dangerous for thousand of years, potentially outlasting human civilization.

    hyperobjects stick to you and are inescapable. you might try to avoid thinking about a hyperobject, but its presence infiltrates daily life like the slow creep of rising sea levels or the omnipresence microplastics in the air you breathe, the water you drink, and the soil your food is grown in.

    hyperobjects exist not in isolation but in constant interaction with other objects and systems. for instance, the carbon cycle connects human industry, ecosystems, and atmospheric chemistry in ways that cannot be disentangled. hyperobjects are real, but they don’t appear fully at once. you can only perceive fragments of them through their effects (melting glaciers or sulfur dioxide in maritime shipping fuel) and through the models used to understand them (e.g., CMIP6).

    hyperobjects push beyond what is called humanity’s epistemic horizon, the boundary of what we can conceptually process. they are too vast in both space and time, existing beyond the direct experience of one human lifespan. the geological timescales of climate change make it challenging to fully perceive its urgency or consequences. the causes and effects of hyperobjects are enmeshed in complex systems, making them harder to discern. global warming involves atmospheric chemistry, ocean currents, human behavior, economic systems and things we aren't even aware of. all of which often manifests indirectly, requiring abstract models, simulations, and data interpretation over time for us to engage with them meaningfully.

    this sheer scale and complexity often leads to psychological overwhelm or cognitive dissonance, resulting in denial or inaction. humans often approach hyperobjects by breaking them into smaller, more manageable parts like focusing on reducing personal carbon footprints rather than addressing systemic industrial ecocide. even just recognizing a hyperobject requires collective action, interdisciplinary research, and systems-level thinking, again, over time. meaningfully addressing climate change would necessitate coordination between nations, localities, municipalities, industries, and individuals.

    art, literature, and philosophy are further ways humans historically seem to engage with hyperobjects. perhaps the abstract, individual, hyperobject-like elements of art itself help to make hyperobjects themselves more relatable and comprehensible, even if only metaphorically. art can influence individuals as well as entire cultures.

    COVID-19, UAPs (unidentified aerial phenomena also known as ''the phenomena''), and AI all exhibit hyperobject-like characteristics. Also consciousness.

    ROGER_WILCO: tak když si naštípeš dříví z lesa za barákem, které nanosíš ručně nebo navozíš na kolečku, tak tohle můžeš zanedbat. Ale snaha biopaliva škálovat byla prostě blbost (ona vychází už z nízké účinnosti fotosyntézy, kdy prostě tu plochu využiješ méně účinně, než solární panely, ale další problém je ta doprava)

    Problém ale je, že příroda nenabízí mnoho carbon-sinků, které by uhlík vyřadily z oběhu na 1000 let. Nemáme mnoho bažin, kde by dnes vznikal přirozenou cestou lignit (hnědé uhlí), max. sem tam nějaké to rašeliniště (jistá naděje spočívá v tom, že v části rozmrzlé tundry by se začaly dělat rašeliniště... jde tu rašelinu nějak uměle vysadit, v tom blátě?)

    To hnojení oceánů na otevřeném moři železem se dnes jeví jako spíše neškodnější forma geoinženýringu, popravdě... taky poměrně méně energeticky náročná, než nějaké drcení olivínu (nebo v čem spočívá v ten pozemní carbon capture). Samozřejmě posypat překyselené půdy nějakým vápencem se jeví neškodné, ale ne všechny půdy jsou překyselené, někde je to zásadité až dost...

    Jste taky tak nadšení jako Elon a Donald,z tohoto vývoje situace?

    USA podle listu za jeho vlády odstoupí od některých klimatických zákonů zavedených za Bidena nebo překreslí národní parky,
    aby se mohlo těžit i v dosud chráněných oblastech.
    Trump podle deníku plánuje také zrušit každý úřad zabývající se snižováním emisí a hodlá odstoupit od Pařížské dohody z roku 2015.

    Na rozdíl od vlád většiny států světa, které se loni shodly na tom, že je potřeba odstoupit od těžby a využívání fosilních paliv, jejichž emise přispívají k oteplování planety, Trump těžbu propaguje. Společnosti těžící ropu a plyn se objevovaly i mezi dárci Trumpovy kampaně.

    US election 2024 live: Donald Trump defeats Kamala Harris to win historic second term as president | US elections 2024 | The Guardian
    https://www.theguardian.com/us-news/live/2024/nov/06/us-presidential-election-2024-donald-trump-kamala-harris-latest-news-updates?page=with:block-672b59298f08243590db2aee#block-672b59298f08243590db2aee

    An election that barely mentioned climate could end up being the most consequential for the planet in modern history. Donald Trump is expected to pull the US out of the Paris agreement, joining just three other countries, Iran, Libya and Yemen.

    He is also expected to cancel many of Biden’s climate policies and, as he said, “drill, baby, drill”, turbocharging oil and gas production.

    This will have dire consequences. CarbonBrief has estimated this will cause an additional 4bn tonnes of carbon dioxide equivalent (GtCO2e) by 2030 emitted from the US. This would negate twice over all of the savings from deploying wind, solar and other clean technologies around the world over the past five years.

    Experts believe a second Trump presidency would end all hope of keeping global warming below 1.5C, the limit agreed by scientists which would avoid the worst impacts of climate breakdown. These include extreme, deadly weather events which can wipe out populations and cause mass deaths, as well as temperatures rising to make some parts of the world uninhabitable, as well as climate related severe disruptions to the food supply as fertile lands become desert.

    It also has global impacts; when right wing parties falsely claim that lowering emissions and switching to a green economy is expensive, and the US is not participating in this effort, they can plausibly ask why other countries are doing that. This is likely to happen in the UK, where politicians are already falsely claiming the Labour government’s green policies will drive up energy bills and cause rationing

    ‘Welfare for the rich’: how farm subsidies wrecked Europe’s landscapes | Farming | The Guardian
    https://www.theguardian.com/environment/2024/nov/02/farm-subsidies-wrecked-europe-environments-common-agricultural-policy

    the environmental aspects of the CAP changes have not worked. The European court of auditors in 2020 found little evidence of a positive impact on biodiversity from the CAP. The European Environment Agency, in its State of Nature report in 2023, found that the EU’s farmed environment had continued to decline, with the health of only 14% of habitats and about a quarter of non-bird species classed as “good”. The CAP is also making the climate worse: about 80% of the budget goes to support carbon-intensive animal food products, according to a paper published this month in Nature.

    Climatic consequences of the process of saturation of radiation absorption in gases
    https://www.sciencedirect.com/science/article/pii/S2666496823000456

    • The impact of anthropogenic increase in atmospheric CO2 concentration on Earth's climate is analysed.
    • The concept of saturation mass is introduced.
    • By comparing the saturation mass of CO2 with the quantity of this gas in Earth's atmosphere, and analyzing the results of experiments and measurements, the need for continued and improved experimental work is suggested to ascertain whether additionally emitted carbon dioxide into the atmosphere is indeed a greenhouse gas.

    COF-999

    We took a powder of this material, put it in a tube, and we passed Berkeley air — just outdoor air — into the material to see how it would perform, and it was beautiful. It cleaned the air entirely of CO2. Everything," said Omar Yaghi, the James and Neeltje Tretter Professor of Chemistry at UC Berkeley and senior author of a paper that will appear online Oct. 23 in the journal Nature.

    "I am excited about it because there's nothing like it out there in terms of performance. It breaks new ground in our efforts to address the climate problem," he added

    Trees and land absorbed almost no CO2 last year. Is nature’s carbon sink failing?
    The sudden collapse of carbon sinks was not factored into climate models – and could rapidly accelerate global heating

    It begins each day at nightfall. As the light disappears, billions of zooplankton, crustaceans and other marine organisms rise to the ocean surface to feed on microscopic algae, returning to the depths at sunrise. The waste from this frenzy – Earth’s largest migration of creatures – sinks to the ocean floor, removing millions of tonnes of carbon from the atmosphere each year.

    This activity is one of thousands of natural processes that regulate the Earth’s climate. Together, the planet’s oceans, forests, soils and other natural carbon sinks absorb about half of all human emissions.

    But as the Earth heats up, scientists are increasingly concerned that those crucial processes are breaking down.

    hurikany se prečíslují


    In the past decade, five tropical storms had wind speeds so high that they should have been classified as “category 6” storms, according to an analysis that suggests the hurricane scale may need to be updated as rising temperatures fuel stronger storms.

    If carbon emissions continue at current rates, we might even see “category 7” storms. “It certainly is theoretically possible if we keep warming the planet,” says climate scientist James Kossin at the First Street Foundation, a non-profit research organisation in New York.

    Officially, there is no such thing as a category 6 or category 7 hurricane. According to the Saffir-Simpson hurricane scale used by the National Hurricane Center (NHC) in the US, any storm with sustained wind speeds of 252 kilometres per hour and over is a category 5.

    Za velké a opomíjené téma letošních prezidentských voleb považuje ochranu klimatu s ohledem na propastný kontrast mezi oběma kandidáty v této otázce. „Myslím si, že to je i mediální slepá skvrna před těmito volbami,“ říká Kaliba, který aktuálně působí jako klimatický zpravodaj ČRo, a připomíná výroky Billa McKibbena z komentáře pro deník The Guardian. Přední americký environmentalista v něm upozorňuje, že dopady znovuzvolení Donalda Trumpa za prezidenta ve světle jeho popírání změny klimatu, aktivní podpory těžby a spalování fosilních paliv by netrvaly roky či dekády, ale milion let. Odvolává se přitom mimo jiné na propočty analytiků z britské organizace Carbon Brief.
