    ‘Code Red For Humanity’: Humans Driving ‘Unprecedented’ Climate Change, U.N. Report Finds
    https://www.forbes.com/sites/roberthart/2021/08/09/code-red-for-humanity-humans-driving-unprecedented-climate-change-un-report-finds/?sh=2635875a5d93

    Global temperatures will likely exceed the 1.5C limit set by the Paris climate agreement within the next 20 years unless swift and drastic action is taken to reduce greenhouse gas emissions, according to a comprehensive assessment of climate science by the Intergovernmental Panel on Climate Change (IPCC), the world’s leading authority on the subject.
    ...
    Atmospheric carbon dioxide levels are also at the highest point in 2 million years, the report said, with agriculture and fossil fuels driving levels of nitrous oxide and methane to 800,000-year highs.
    ...
    Even in best case scenarios, some of the changes—including sea level rise—are irreversible for millennia.

    Asset Revaluation and the Existential Politics of Climate Change | International Organization | Cambridge Core
    https://www.cambridge.org/core/journals/international-organization/article/asset-revaluation-and-the-existential-politics-of-climate-change/0963988860A37F6988E73738EA93E0A1

    Whereas scholars have typically modeled climate change as a global collective action challenge, we offer a dynamic theory of climate politics based on the present and future revaluation of assets. Climate politics can be understood as a contest between owners of assets that accelerate climate change, such as fossil fuel plants, and owners of assets vulnerable to climate change, such as coastal property. To date, obstruction by “climate-forcing” asset holders has been a large barrier to effective climate policy. But as climate change and decarbonization policies proceed, holders of both climate-forcing and “climate-vulnerable” assets stand to lose some or even all of their assets' value over time, and with them, the basis of their political power. This dynamic contest between opposing interests is likely to intensify in many sites of political contestation, from the subnational to transnational levels. As it does so, climate politics will become increasingly existential, potentially reshaping political alignments within and across countries. Such shifts may further undermine the Liberal International Order (LIO); as countries develop pro-climate policies at different speeds and magnitudes, they will have incentives to diverge from existing arrangements over trade and economic integration.

    PER2: U syngasu ujsou do budoucna v zasade 2 moznosti:
    a] plazmove zplynovani odpadu
    b] biotechnologicke
    Oboji s dodatecnem dotovanim patrne vodikem a vodni parou.

    Dokavad nepojedou technologie nasledneho vyuziti syngasu ve velkem, nikdo nepostavi velkou alterrnativni produkci syngasu. Tzn. nejdriv aplikaci syngasu a pak gradientne prejit z fosilu.
    Pocita se zejmena se syntetickymi palivy, ale tam v pripade zpracovani odpadu neni vubec resen problem uhlikove stopy. Naopak jak bych trval na materialove vyuziti ktere setri uhlikovou stopu hned 2x (samozrejmne pokazde s nejakou procentualni efektivitou).

    A.2.2 Global surface temperature has increased faster since 1970 than in any other 50-year period over at least the last 2000 years (high confidence). Temperatures during the most recent decade (2011–2020) exceed those of the most recent multi-century warm period, around 6500 years ago13 [0.2°C to 1°C relative to 1850– 1900] (medium confidence). Prior to that, the next most recent warm period was about 125,000 years ago when the multi-century temperature [0.5°C to 1.5°C relative to 1850–1900] overlaps the observations of the most recent decade (medium confidence). {Cross-Chapter Box 2.1, 2.3, Cross-Section Box TS.1}

    PETER_PAN: Jinak tedka bude probihat nekolik mesicu postupny vydavani zprav, v roce 2022 potom dalsi souhrnej report. Jsem zvedavej, jak se s tim media popasujou. Jestli budou schopny nadraftovat nejaky kompetentni lidi na pokryti. Jsem zvedavej, co komentatori, ktery musej kazdej tejden chudaci generovat nazory na vsechno... Pritom tohle je tema, kde se clovek pro nejakou lepsi orientaci v debatach potrebuje vzdelavat roky.
    No moc optimistickej oohledne medialniho pokryti nejsem .]]

    The Crisis: Four States of Denial
    … As the IPCC gives it latest report
    The first state of denial is the one everyone is familiar with: that climate change does not exist or, if it does, it is not caused by humans. The vast majority of people are now over this denial (apart from some Republican voters in the US). There is such a thing as facts and, well, facts are facts.
    The second state of denial is that we do not have to engage in an immediate and massive transformation of our economies and societies. There is the pretence for instance that 1.5C is still possible, and that we can stay under 2C by ambling down to “net zero” by 2050. We cannot. As Sir David King the former chief scientific advisor to the UK government has put it “what we do in the next 3-4 years will determine the future of humanity”. This is because the world is already over 500 ppm of CO2 equivalent (the combined effect of all greenhouse gases) and the amount of heat being trapped by the planet has doubled in the last 15 years: “There is no carbon budget left”. Or as Norman Loeb the lead researcher on the heat imbalance research project made clear, we are heading into ecological destruction of unimaginable proportions. The “climate industry” is in denial about this: the diplomats, the political parties, the NGOs, Fridays for a Future, establishment scientists, and the liberal elements in XR. However many individuals in these social networks privately understand the situation perfectly well, but generally only those that are retired speak about it publicly.
    The third state of denial is that we can create this transformation without mass and high level civil resistance. There is massive denial about this even in the supposedly radical elements of the environmental movement. Hence the false compassion that says “you don’t have to get arrested”. The whole of the Left is in denial about this – where is Black Lives Matters, where is the feminist movement, where is the labour movement? They all have the quaint humanist delusion, rooted in their “Enlightenment” philosophy, that nature something separate from society. That’s why Guardian articles only talk about sea level rise, temperature rises, and methane release but hardly ever talk about the secondary social effects of mass slaughter and rape, or genocide and fascism. Covid did not manage to break the denial but climate collapse surely will. The only thing that puts us in the ballpark of effective change given we have no time is economic disruption (closing of ports, motorways, pipelines etc) and/or the mass occupation of the centre of state capitals. Dressing up in costumes, going to ghostly international conferences, and moaning on social media, with all due respect, is just another displacement activity at this stage in the game.
    The fourth state of denial is that the present political system will respond in time to this civil resistance. It will not. Only a political revolution will result in the World War Two transformation we now need. This is not a political statement but a sociological one – conventional political regimes have limits on how fast they can change. And political revolutions will inevitably happen once populations, probably later this decade, come face to face with the truly horrific depth of the fiscal crises and systemic breakdowns we face – given that civilisational collapse is now locked in for large parts of the world. They will demand the removal and prosecution of the political class “who knew all along but did nothing” and institute new political regimes: in other words, there will be revolutions. With a bit of luck they will be nonviolent and involve the institutionalisation of citizens assemblies in northern Europe, Canada and Australia. The US and southern Europe are more likely to descend into civil war, fascistic authoritarianism, and/or social collapse as a secondary effect of hundreds of millions of refugees fleeing from the depopulating sub tropics in an attempt to escape mass starvation and the deadly threat of wet bulb temperatures – Central America, the Middle East, India, and Africa, South West Asia.
    This is where we are in 2021. The “crucial decade” was 2010-20, as we were told at the time, not the 2020’s. The 2020’s will be the decade of consequences. Like the people who understood the real nature of the Nazi project in the 1930’s and took in the Jews during World War Two, those that overcome these states of denial, and act in response to the real nature of the world today, are not predominately part of either the Left or Right, or of a particular religious or cultural group. What they have in common is what Tim Snyder, author of “Black Earth, Holocaust as History and Warning” calls “self knowledge”: the personality structure that is able to overcome the pressure to conform to the herd, and the ethical inability to stand by as society descends into evil.
    In the next two to three years the prevention of humanity’s greatest hell of rape, slaughter, and starvation will depend on whether this small group of people around the world go into active and unlimited nonviolent resistance against the carbon regimes. These people already know who they are.

    Within the next two decades, temperatures are likely to rise by more than 1.5C above pre-industrial levels, breaching the ambition of the 2015 Paris climate agreement, and bringing widespread devastation and extreme weather.
    Only rapid and drastic reductions in greenhouse gases in this decade can prevent such climate breakdown, with every fraction of a degree of further heating likely to compound the accelerating effects, according to the International Panel on Climate Change, the world’s leading authority on climate science.

    Odborníci se už dříve shodli, že klíčovou hranicí ve změnách klimatu je oteplení o 1,5 stupně Celsia ve srovnání s předindustriálním obdobím. Při respektování nejambicióznějšího plánu, který zahrnuje naprosté zastavení jakýchkoliv emisí CO2 a razantní snížení všech ostatních emisí, překonáme tuto teplotní hranici zhruba za 20 let. Teplota se nejprve přehoupne přes hranici oteplení o 1,6 stupně Celsia a poté ke konci století bude klesat na 1,4 stupně Celsia ve srovnání s dobou před průmyslovou revolucí, uvádí zpráva IPCC. Celosvětově se již oteplilo o 1,2 stupně Celsia a lidstvo kritickou hranici nejspíš překoná zhruba o deset let dříve, než vědci původně odhadovali. Panel OSN novou zprávou apeluje na politiky i firmy, aby razantně změnili svůj přístup k výrobě a pojetí ekonomiky, které jsou hlavní příčinou globálního oteplování.
    Bez lidského přičinění by velmi pravděpodobně nenastal žádný z extrémních klimatických jevů posledních let, jako jsou vlny veder na souši i na moři, sucha nebo záplavy. „Je velmi pravděpodobné, že epizody s vydatnými srážkami budou ve většině regionů s dalším globálním oteplováním intenzivnější a častější,“ uvádí se ve zprávě.

    TUHO: Zpráva varuje, že některé zásadní a negativní dlouhodobé změny už nelze ovlivnit. Ať už do budoucna vlády jednotlivých zemí přijmou jakákoliv opatření, budou i nadále tát ledovce, bude pokračovat acidifikace oceánů a stoupat hladina světových vod.

    I přes pesimistický výhled ale zpráva IPCC konstatuje, že je stále reálné dodržet závěry Pařížské dohody z roku 2015, jež si vytkla za cíl nedopustit zvýšení globální teploty do konce století o více než 2°C a pokud možno pouze o 1,5°C. Podmínkou je ovšem omezení celosvětových emisí o polovinu do roku 2030 a dále na tzv. čistou nulu do roku 2050. Nicméně i při zachování globálního oteplení do 1,5°C bude docházet k extrémním a bezprecedentním přírodním katastrofám, varují vědci.
