    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.

    ja som tiez kedysi listie palil, ale bolo z toho akurat kopu dymu, komposter ho prekvapivo vie dobre spapkat, ale mame iba 1 strom, inak by som asi potreboval viac komposterov

    OMNIHASH: tak předpokládám že logika toho je to, že třeba v lese list spadne a přirozenou degradaci se z něj CO2 zase do atmosféry vrátí. Btw ty s tím listím děláš co? Spousta lidí ho spálí.

    KEB: mno já nevím, o listech už kolega jůtuber slyšel? Ty CO2 netrasfromující vyrostlý stromy mi jich nějakým záhadným způsobem vygenerujou ročně patnáct koleček... jinak sem teď někde zahlíd studii, že jedním z nejlepších přírodních carbonsinků jsou plovoucí rostliny a někde v Hudsonově zálivu našli na dně metrový nánosy z poslední doby meziledový.

    SHEFIK: tak snad jde zhruba o ty mraky... ve dne ochlazujou, protože odráží sluneční záření zpět do vesmíru, v noci naopak brání ochlazování povrchu i spodní atmosféry. Dlouho se nevědělo, který vliv převládá, nakonec se dospělo k tomu, že spíše oteplují - ale ne katastroficky.

    EVs Three Times better for Environment when Ride-Hailing −
    https://evobsession.com/evs-three-times-better-for-environment-when-ride-hailing/amp/

    Replacing a traditional ride-hailing car with an electric vehicle would deliver three times the environmental benefits and emission reductions, according to a new study. The finding comes as a new cost analysis by T&E shows that e-vehicles are cheaper to run for Uber drivers in many European cities, and Uber in Portugal says it will only take on new drivers if they have an EV.

    Renewable sources of power have taken over for the first time in 2020, generating 40% of European Union electricity, while fossil fuels generated 34%, independent think-tank Ember said in a half-yearly report.

    In Spain, coal generation fell 58% in the first six months of the year, even before half its remaining plants closed in June as they no longer complied with EU emissions rules. The pace of plant closures in Spain, with 69% of the entire fleet to be shuttered between 2020 and 2021, has no precedent, Global Energy Monitor program director Christine Shearer said.

    In Portugal, coal generation fell 95% in the first half of 2020, Ember said. Last week major utility EDP brought forward its Iberian plant closures to 2021, after writing down their value last year.
    The Netherlands, Austria and France all saw reductions of more than 50%. Sweden and Austria closed their last plants in March.

    In Germany coal generation fell 39%, taking it for the first time below Poland, which now generates as much electricity from coal as the EU’s remaining 25 countries put together.

    Instead of worrying about adjusting our climate action targets, we can just worry about hitting the targets we’re already quite late to.

    Global livestock supply chains have significantly altered nitrogen (N) flows over past years, thereby threatening environmental and human health. Here, we provide a disaggregated assessment of the livestock sector’s impacts on global N flows and emissions, including international trade. The results show that the sector currently emits 65 Tg N yr−1, equivalent to one-third of current human-induced N emissions and sufficient to meet the planetary boundary for N. Of that amount, 66% is allocated to Asia and 68% is associated with feed production. Most emissions originate from locally produced animal-sourced food, although N emissions embedded in international trade are significant for some importing countries. Given the magnitude of its impacts and its central role in both domestic and international N challenges, the livestock sector urgently requires a global initiative to tackle N pollution while supporting food security.

    86 % Čechů by se rádo zbavilo závislosti země na uhlí, a to především kvůli zastavení ničení krajiny a znečišťovaní ovzduší.
    Vyplývá to z výzkumu publikovaného podnikatelským a inovačním centrem BIC Brno ve spolupráci se Svazem moderní energetiky, který vznikl v rámci projektu spolufinancovaného Technologickou agenturou ČR.

    How much warming will greenhouse gas emissions cause in the coming years? It’s one of the most fundamental questions about climate change—and also one of the trickiest to answer.
    Now, a major study claims to have narrowed down the range of possible estimates.
    It presents both good and bad news. The worst-case climate scenarios may be somewhat less likely than previous studies suggested. But the best-case climate scenarios—those assuming the least amount of warming—are almost certainly not going to happen.

    Sanders a Omar navrhuji zastavit dotace fosilniho prumyslu

    Yet, as fossil fuel emissions cook the planet and wreak a mounting toll of destruction, the federal government gives oil, gas and coal companies nearly $15 billion per year in direct federal subsidies and already directed billionsmore in support through coronavirus relief programs this year.
    New legislation from five of the country’s top progressive lawmakers, including Rep. Ilhan Omar (D-Minn.) and Sen. Bernie Sanders (I-Vt.), aims to cut the fossil fuel industry off, HuffPost has learned.
    On Friday, the lawmakers plan to introduce a bill barring fossil fuel companies from receiving COVID-19 funding, ending federal support for fossil fuel projects at home and abroad, and abolishing dozens of tax loopholes and incentives for the industry.
    “It’s past time we end the billions of taxpayer subsidies to fossil-fuel companies,” Omar said in a statement. “Our focus right now needs to be on getting the American people through this difficult, unprecedented time, not providing giveaways to polluters.”
