    TUHO: ja v tom jeste vidim tu bezmoc obycejnych lidi. naomi klein pise o "germans and belgians", jako by bylo dulezity, co si oni mysli. germans and belgians jsou ale ve skutecnosti ve stejne pozici jako byli pred sto lety. kdyz se cisar pan rozhodne, ze bude valka, bude valka. v zakopech na Stedry den muzou na sebe nemci a francouzi navzajem zpivat koledy, ale rano zase vstanou a pujdou se nesmyslne strilet, protoze vrchnost ma dojem, ze je to vyhodny.

    stejne tak vrchnost zatim nema pocit, ze je vyhodny stabilizovat klima. vrchnost vzdycky zdrhne nekam do citadely, az se vyjasni, kde to bude nejstabilnejsi. viz jak voytex nize psal, ze merkel kvantova fyzicka kamoska schellnhubera 30 let vidi a vi jak to jde do prdele, ale s kapitanama prumyslu muze tak akorat obedvat, nemuze je nijak zmenit

    cili ano, zasahne to i evropu. vrcholne kapitalisty to ale nezasahne (z jejich modelu nevyplyva ze by jiz nyni bylo zadouci radikalne menit kurz)

    YMLADRIS: Jj, castej argument je, ze "dopady jsou uz tak ocividny, ze se nedaj ignorovat". A to si myslim, ze uplne tak nefunguje. Ty dopady totiz ukazujou na zmenu klimatu jenom skrze velmi komplikovanej aparat vedecky analyzy. Jinak je to izolovana katastroficka udalost, ktera tady byla vzdycky (a vzdycky bude). No a tim, jak je zkousnuti ty vedecky verze emocionalne narocny, tak ziskava na atraktivite narativ, ze to je vsechno vedeckej komplot, prefukovani a vlastne se nic tak dramatickyho nedeje.

    GOJATLA: species suicide? spis modern civilization collapse

    YMLADRIS: Asi ne. Jen to trochu komplikuje tu představu, že na naše emise doplatí někdo jiný. Climate genocide není až tak projev sobectví, jako spíš další level popření, lidé neví co s tím, doufají, že se jich to nedotkne a třetí svět má prostě smůlu. Když na to upozorníš, tak vyvoláš jen vztek. Pocity viny ale nejsou na místě, ve skutečnosti jsme ale na cestě ke species suicide. Spravedlnost bude.

    Stuck in the Smoke as Billionaires Blast Off
    https://theintercept.com/2021/07/23/stuck-in-the-smoke-as-billionaires-blast-off/
    Naomi Klein

    ...something dramatic is changing in public perception: a dropping away of the fantasy of safety in the wealthier parts of the world, as well as the beginnings of cracks in the faith that money and technology will find solutions just in the nick of time.

    Climate inaction in the rich world was never really about denial. Belgians and Germans knew climate change was real; they just thought poorer countries would bear the brunt of it. And up until recently, they were right.

    In this summer of fires and floods, it appears to be dawning on many that even this sinister form of climate apartheid is likely an illusion for all but the ultrarich. As Nasheed said, and as the New York Times echoed in an ominous headline overlaid on a photograph of a burning building: “No one is safe.” We are all trapped in this crisis — whether under that relentless pall of smoke, or in a heat that hits like a physical wall, or under rains and winds that will not stop.

    Komentar k nedavnemu IEA reportu o vzacnych kovech potrebnych pro dekarbonizaci"

    It doesn’t have to be this way, and here are three reasons why:

    The IEA itself highlights that “recycling relieves the pressure on primary supply,” and that recycled copper, lithium, nickel, and cobalt from spent batteries could reduce combined primary supply requirements by approximately 10% by 2040;
    Research that Earthworks recently published, prepared by the Institute for Sustainable Futures at the University of Technology Sydney, shows much more optimistic results of 25-55% potential demand reduction through increased recycling of nickel, cobalt, lithium, and copper from EV batteries alone;
    Recycling has the potential to be a major source of jobs, as EV and other batteries capable of being recycled increase in production. This job can and must be done with the strictest labor and safety laws.
    Other strategies, such as public and collective transportation solutions, have significant potential to reduce demand for metals used in electric vehicle batteries. It’s not enough to move from one type of “take-make-waste” extraction-based linear economy; to comprehensively address the climate crisis the world writ large (but especially wealthy and/or Western countries) must commit to fundamentally reshaping our approach to consumption. Specifically, this means moving towards what the UK-based NGO War on Want calls a circular economy, not just for minerals but for all resources and goods, and eventually a circular society, “in which not only waste is minimised, but consumption itself is questioned.” We must no longer assume the planet can handle infinite growth and production.

    TUHO: tak ono to souvisí, protože jedno vlhké jaro podle všeho nestačilo, aby se obnovila integrita půdy a holt se to zřejmě o to snadněji spláchlo. na většině míst jsou vidět přívaly bláta. (to město v Německu, které si na svém okraji kutalo obří jámu, to je kapitola sama pro sebe, to ani nespadá do kapitoly krimatická klize, to je poučka z obecného betonářství, že se vytěží hromada písku do betonu a pak se do té díry spláchne okolí :-)

    TUHO: A Belgie minuly rok

    Belgium is facing its driest May since the 19th century, with conditions that have stunted crop growth and cut yields in the agricultural province of West Flanders.
    The region’s governor Carl Decaluwe on Monday banned water pumping from streams running off the Yser river, after levels fell below 2.9 metres.
    “We had to do it because otherwise the damage would be irreparable,” Decaluwe said, adding a prolonged drought could cost the region “tens of millions” of euros in damages.
    “We haven’t seen such low water levels in 30 years, and we are experiencing the driest weeks in 120 years.”
    For farmers, who usually pump riverwater into their fields, the ban has left them waiting for rain.
    “Normally I get 50 to 60 tonnes of corn from an acre. But now we will have to be happy with only half of that - on the condition that it will start raining again,” Joel Van Coppenolle, a farmer from the town of Kaaskerke, said. As he spoke, he stood in fields where his corn seedlings are half their usual size, and the soil is cracked and dusty.

    Belgium has been hit by floods for the second time in just over a week.
    The provinces of Namur and Walloon Brabant southeast of the capital city Brussels were among the worst hit, after thunderstorms and heavy rain reached the country on Saturday.

    Herrington, 39, says she undertook the update (available on the KPMG website and credited to its publisher, the Yale Journal of Industrial Ecology) independently “out of pure curiosity about data accuracy”. Her findings were bleak: current data aligns well with the 1970s analysis that showed economic growth could end at the end of the current decade and collapse come about 10 years later (in worst case scenarios).

    The timing of Herrington’s paper, as world economies grapple with the impact of the pandemic, is highly prescient as governments largely look to return economies to business-as-usual growth, despite loud warnings that continuing economic growth is incompatible with sustainability.

    Earlier this year, in a paper titled Beyond Growth, the analyst wrote plainly: “Amidst global slowdown and risks of depressed future growth potential from climate change, social unrest, and geopolitical instability, to name a few, responsible leaders face the possibility that growth will be limited in the future. And only a fool keeps chasing an impossibility.”

    Extreme weather takes climate change models ‘off the scale’

    Extreme weather takes climate change models ‘off the scale’
    Scientists say the shifting pattern of the jet stream is exacerbating the effects of climate change

    ...

    Climate scientists say the severity of these events is simply “off scale” compared with what atmospheric models forecast — even when global warming is fully taken into account.

    “I think I would be speaking for many climate scientists to say that we are a bit shocked at what we are seeing,” said Chris Rapley, professor of climate science at University College London. “There is a dramatic change in the frequency with which extreme [weather] events occur.” 

    From the deadly flooding in Germany last week, to scorching heat in Canada, and a deluge in the Black Sea region, the pace and scale of catastrophic damage has been almost unimaginable, even for experts who have spent their lives studying it.

    One driver behind many of these events is the shifting pattern of the jet stream, a fast-flowing band of air that governs weather in the Northern hemisphere. It is becoming slower and wavier, particularly in summer months.

    ...

    This means heatwaves and drought (linked to high pressure systems) and flooding (linked to low pressure systems) both become more persistent.

    ...

    Mann is worried that current models do not reproduce the jet stream behaviour accurately. “This means they are underestimating the magnitude of the impact of climate change on extreme weather events,” he says.

    “While the overall warming of the planet is pretty much in line with climate model predictions from decades ago, the rise in extreme weather events is exceeding the predictions,” Mann notes.

    PER2: taky to muzes vest dal, za protrzeni prehrad muze clovek, protoze postavil prehrady. a kazda prehrada jednou skonci, bud managovane (vypustenim) nebo nemanagovane (vyschnutim, protrzenim). :)

    co se tyce klima zmeny, ta je pricinou v tom smyslu, ze ty vykyvy jsou vetsi a proto snadno presahnou planovanou kapacitu infrastruktury.

    v cine je pres 100.000 vodnich nadrzi a velka cast se stavela v 50. -70. letech (zivotnost byva kolem 50 let) skoro vesina jsou sypane hraze a na jejich udrzbu se davaj stejny prachy asi jako v cechach na cokoliv statniho, podle statistik za poslenich nekolik desetileti je v cine rocni sance na dam failure (0.088%) 4x vetsi nez prumerne ve svete (0.02%), kolem roku 2005 v cine kazdy rok selhalo cca 70 prehrad/hrazi, nevim jaky cisla maji ted

    neni cela historie ciny zalozena na zaplavach a ze nejlepsi vudce bude ten, ktery vodu dokaze zkrotit? rekl bych ze na podfinancovany hraze bez penez na udrzbu a rozvoj obrovskych mest pod nima za poslednich par dekad si vedou porad docela dobre
