    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.

    PER2: tak ono to ma asi vypovedni hodnotu jen kdyz je to v kontextu napr. nejaky ty atribucni studie. coz pokud je cloveku nad 40 je naprosta kravina a neoverena teorie.

    nic, jedu lyzovat do dubaje.

    YMLADRIS: presne tak, a proto uz je to davno, jeste nez xchaos a nyrlem booknuli auditko, co jsem prisel s konceptem klimaticke trampoliny. pokud postavime dostatek trampolin, tak jak klimaticka zmena bude dopadat, trampoliny ji budou odrazet. dejte mi dostatecne velkou trampolinu a odrazim jakoukoliv katastrofu. pak jdu rovmou na hokej

    Trochu o Norhausovi DICE modelu na Skeptical Science.

    Matheus Grasselli, another of the speakers, presented quite a detailed analysis of William Nordhaus’s DICE model. He highlighted how it essentially assumes that the system is always in equilibrium, even if there has been some major shock. He also showed how the results depended strongly on assumptions about damages. What I thought was particularly interesting is that in the DICE model, everything seems to recover even in extreme scenarios.

    So, it seems that there is a general view that there are many valid criticisms of these economic analyses. However, at the risk of being accussed of being deferential again, I do think there are many economists who acknowledge this and who are trying to do more appropriate analyses. I do think that some of the damage estimates are way too low, and that the results of some of these analyses have been presented in ways that then play into the hands of those who want to minimise the impact of climate change.

    NYRLEM: Ta korelace je zpusobena tim, ze mnozstvi CO2 meni radiacni bilanci atmosfery, to je fakt znamej uz od poloviny devatenactyho stoleti. Vsechno soucasny vedeni o fyzice atmosfery, reakci oceanu, biosfery, kryosfery, chemie atmosfery etc rika, ze se bude oteplovat a ze tam neni pouze korelace, ale kauzalni vztah.
    Zaroven uz mame nekolik desetileti uspesnejch predpovedi klimatickejch modelu. Ale z hlediska teorie vedy jsou teorie fundamentalne neoveritelny tak ci tak, takze o "neoveritelny teorii" muzes mluvit do nekonecna.
    Point je, ze mame miliardu velmi zavaznejch duvodu se domnivat, ze nas ceka extremni pruser, pokud rychle nezvednem prdel a neco s tim neudelame.

    PALEONTOLOG: nejak nechapu, co se mi snazis rict - ja mluvim o teplote, ty mi napises neco o hokejce, dam ti tam delsi teplotni radu, kde zadna hokejka neni a na to konto mi pises, ze v tom plavu a odkaz bez komentare. Mozna si to nejdriv znovu prohledni co jsem psal..

    za vedro muzou americani, protoze jejich rakety saturn V pohnuly zemskou osou.

    no videli jste ty rakety?? vzdyt to bylo obrovsky. takze se nelze divit nasledkum.

    PALEONTOLOG: tak urcite .. to ze teplota a co2 maji momentalne nejakou korelaci neznamena, ze trend zustane stejny pri vyssi koncentraci co2. To je neoverena teorie.

    NYRLEM: graf od konce pleistocenu bude stejnej, jen ta hokejka bude ostrejsi a krivka vyhlazenejsi a tupci budou rvat, ze na kratsim grafu to nebude vypadat extremne.

    TUHO: omg ... ono je lepsi rikat, ze to je stupen od industrial revolution namisto od konce male doby ledove, to vydesi vic blbcu :D ja k tomu reknu jen tolik, ze se jedna o teorii. Kdyz se podivas na 20 let stare predpovedi, leccos se naplnilo a leccos ne, napriklad hladina oceanu se nezvedla podle predpovedi a to byl hlavni argument pro rozpoutani noveho stehovani narodu ..

    A k tematu. Neco pokryvajici klimaticka rizika

    At one degree – the world we are already living in – vast wildfires scorch California and Australia, while monster hurricanes devastate coastal cities. At two degrees the Arctic ice cap melts away, and coral reefs disappear from the tropics. At three, the world begins to run out of food, threatening millions with starvation. At four, large areas of the globe are too hot for human habitation, erasing entire nations and turning billions into climate refugees. At five, the planet is warmer than for 55 million years, while at six degrees a mass extinction of unparalleled proportions sweeps the planet, even raising the threat of the end of all life on Earth.
