    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.

    TUHO: Dansgaard–Oeschger events treba
    v poslednich 300.000 letech se teplota menila dost drasticky a dost rapidne, rikat ze ne, je absolutni nonsense (samozrejme vyjma holocenu)
    to ze se ted drasticky zvysuje teplota v soucasnosti zaroven nepopiram, jen jsem dost alergicky na to, kdyz nekdo rika, ze driv to byla pomala zmena a pohoda nesrovnateolna s tim co se deje ted... cim vic novejsich dat/studii mame, tim vic se ukazuje ze ta zmena byla kolikrat dost rapidni (a akademici mezi sebou stale vedou dost vasnivy bitvy, ze to tak urcite nebylo/bylo ... cim vic dat budeme mit , tim si budem jistejsi)

    MATT: dryas ze nebyl o vymirani? "At the onset of the Younger Dryas there was a massive, worldwide extinction of mammals weighing over 40 kg. It is estimated that 82% of these animals disappeared in North America, 74% in South America, 71% in Australasia, 59% in Europe, 52% in Asia, and 16% in Sub-Saharan Africa. Fossil evidence suggest the disappearances were very sudden."

    PER2: Btw je divny, ze tam neni zadny otepleni v soucasnosti. Co je to za zdroj vubec? Sipka tam sice ukazuje, ale v paleoklimatologii je dost zasadni, co ukazje bod 0. Casto to byva rok 1950, ale prvni data point muze byt klidne roku 1850 (celkem logicky, pokud je to analyza ledovcovejch jader):

    TUHO: Jinak k tyhle rekonstrukci se jeste slusi dodat, ze posledni vyzkum ukazuje, ze doba ledova byla zrejme vyrazne studenejsi (o 3-5 stupnu) nez donedavna rekonstrukce ukazovaly. Celkem dost radikalni zmena, jsem prekvapenej, ze se to vic nedebatuje. Nema k tomu nekdo nejaky detaily?

    PER2: Problem trochu je, ze tohle je lokalni rekonstrukce teplot v Gronsku. Lokalni rekonstrukce jsou samo vzdycky dost variabilnejsi. Globalni rekonstrukce teploty tak dramaticky nejsou (coz mj znamena, ze lokalne muzeme ocekavat vyrazne dramatictejsi zmeny v ruznych castech sveta).

    A jako nejaka snaha je hezka, jenom mi prijde, ze politici (bez silne podpory obyvatelstva) s tim nejak radikalne nepohnou. Ale asi chapu, ze myslis, ze by jako stat mohl ty eko cesty par firmam povolovat diky dynamicke legistlative a taky investovat do novych technologii.

    wen BOE? soon


    We really have to take into account a Blue Ocean Event this year. This means we've only left less than 1M square kilometer of sea ice in August or September.

    The water near the sea-ice border is up to 6°C warmer than during a normal July!!

    The ice is losing 10 to 15 centimeters of thickness now each day!!

    We’re Not Going to Make it to 2050 | by umair haque | Jul, 2022 | Eudaimonia and Co
    https://eand.co/were-not-going-to-make-it-to-2050-5398cf97b805

    Extinction — the Event we’re now entering — is going to be the single greatest occurrence in human history. We have never experienced anything remotely like it in the 300,000 years we’ve existed, because the last time it happened was 65 million years ago. Extinction will cleave time, shape politics, and define culture forevermore, after us. Our progeny will regard us the way we regard Stone Age people, or maybe medieval sorts — why didn’t they do anything, they’ll wonder? Why did they sit there glued to dumb Marvel Movies and debating pronouns and letting demagogues scapegoat and hate…while their planet died?

    What we are doing is inadequate. You don’t have to think too hard about it. Our civilization’s attempts to combat Extinction so far have resulted in…this. This dystopia we currently live in, where Europe’s on fire, inflation’s spiking, Covid never goes away, and all the rest of it. Our efforts are self-evidently inadequate. Things are this bad right now. Go ahead, and think about 2025. And shudder. Most of us can’t even imagine the world in 2030, or 2040. Will there even be one? What will be left of this thing we once called civilization?

    Vague goals to hit “net zero” by 2050 are like standing in the basement of a burning house, and agreeing to call the fire department in the morning.

    Dnes nás čeká tropický den. Na tyto dny bychom si však dle výhledu modelů měli zvykat a budou čím dál častější. Pozorovaný počet dokonce v posledních letech odpovídá spíše tomu, co modely předpokládaly až kolem roku 2050.

    aspon ze v australii je vsechno v poradku

    The survey of Australia's ecological systems - conducted every five years - found widespread abrupt changes.
    Nineteen ecosystems are on the brink of collapse
    There are now more non-native plant species in Australia than native ones
    Australia has lost more species to extinction than any other continent
    All bar one category of environment examined has deteriorated since 2016, and more than half are now in a "poor" state.

    lekce z rewildingu, aneb bez hyperpredátoření to nepůjde

    ‘We make nature here’: pioneering Dutch project repairs image after outcry over starving animals | Rewilding | The Guardian
    https://www.theguardian.com/environment/2022/jun/21/pioneering-dutch-rewilding-project-oostvaardersplassen-works-to-rebuild-controversial-reputation-aoe

    “Back-bred” animals resembling their extinct relations that would have lived in Europe during the Pleistocene, or ice age, arrived: Konik horses from Polandin 1983; Heck cattle from Germany in 1984; and red deer from Scotland in 1992. They were hardy and fitted in with the carefully cultivated wild aesthetic. This work drove radical changes, pushing traditional conservation towards “nature development” with large herbivores as the “ecological main structure”, which is now common thinking in rewilding.

    In 2018, after an outcry over the deaths of so many animals, a committee coordinated by the provincial government called for an end to the policy of allowing “natural processes” to govern herbivore populations, and said numbers must be kept below 1,500. Today a vet comes regularly to check on the animals. Those in bad condition are fed over the winter. When numbers increase too much, they are moved to new areas or killed, and deer and horse carcasses can be sold as “wild meat”.
