    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.

    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.

    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.”

    When Sam Kern started working at Google four years ago, she believed she could drive change as an insider. If she could just "get the ear" of the right executives, Kern thought, she could convince them to move the company in a new direction on climate and sustainability.
    But over time, Kern said she realized, powerful moneyed interests made that impossible.
    Kern, a user experience engineer, described company leaders as "putting up a wall between the business interests and human interests," even as they seemed to recognize the severity of the climate crisis, which made conversations with them feel emotionally disconnected.
    ...
    Kern left Google in May and joined the radical climate activist group Extinction Rebellion, which earlier this month launched a digital campaign, bigtechlovesbigoil.com, targeting tech majors Google, Microsoft and Amazon for providing oil and gas companies with cloud computing services, custom artificial intelligence and machine learning tools.

    Varoufakis o EU covid recovery planu

    So, why is it that, although I endorse the idea of mutualised debt as a necessary condition for European unity, I believe that the EU’s latest decision is another step in the direction of Europe’s disintegration? For three reasons.

    First, the recovery fund is a distraction from the elephant in the room: massive austerity. According to the International Monetary Fund, the eurozone’s total 2020 income will fall by 10%, causing an average budget deficit of more than 11%, with weaker countries such as Italy and Greece facing a much larger drop.

    That would not be catastrophic per se, if it were not for the determination of Berlin and other governments to push member states to balance their books by 2021 (as witnessed by the 11 June Eurogroup communique). Even if the nascent recovery brings down, for example, Italy’s budget deficit to, say, 9%, to balance its books Rome must impose a cruel level of austerity equal to a new 9% of GDP in cuts and taxes. Similarly with Greece. Given that even Germany will have to practise austerity to balance its budget, the whole continent will be treated to an intensification of the doom loop between austerity and recession.

    Second, the recovery fund is (macroeconomically) puny. For it to defend the union, it should pack a fiscal boost comparable in magnitude to the austerity tsunami down the line. It does not. Take Italy and Greece again, countries that must face down immense austerity. How much of this shock can the recovery fund monies help absorb? Not a lot, is the answer.

    To arrive at a precise answer, we must first ignore the new loans on offer from the recovery fund (since new debt has never helped the insolvent) and concentrate exclusively on net grants. Italy has been allocated around €80bn and Greece €23bn. However, every member state must take on part of the new €750bn EU debt. Italy, for example, is liable for just under 13% of this debt while poorer Greece is liable for 1.4%. Once we subtract these new debts, Italy’s and Greece’s net grants come to just over €30bn and €12bn respectively – or 0.6% and 2% of GDP on an annual basis between 2021 and 2023. Compared to the prospect of austerity equivalent to 9% of GDP, which will be required to balance their budgets, these are puny sums.

    Third, the political conditions under which the funds will flow are a Eurosceptic’s dream. When a recession hits the UK, the government’s budget deficit rises automatically as benefits flow disproportionately towards the most affected regions. The beauty of such a proper fiscal union is that no politician can decide which region gets which transfer. Imagine the sheer awfulness if parliament had to debate how much would be transferred to Cumbria, to Norfolk or to north Wales from Surrey, Sussex and west London. Britain would be wrecked by divisions that make Brexit look like an amicable affair. And yet this divisiveness has been baked into the EU recovery fund, complete with country allocations drawn up even before we know the effects of the recession on each region. It is almost as if the whole thing were designed by a cunning Eurosceptic.

    yep yep, we are heading in the right direction

    Over the past few weeks there have been many reports of localized air quality improvements as the world has locked down to combat the coronavirus pandemic. However, no one should think that the climate crisis is therefore over—far from it.
    Record global carbon dioxide concentrations despite COVID-19 crisis
    https://www.unenvironment.org/...record-global-carbon-dioxide-concentrations-despite-covid-19-crisis


    Researchers studying one of the most important and vexing topics in climate science — how sensitive the Earth’s climate is to a doubling of the amount of carbon dioxide in the atmosphere — found that warming is extremely unlikely to be on the low end of estimates.

    Diky tani Arktidy muze RUsko dodavat do Ciny ropu severni cestou. Zacaly minuly tyden. Hura!

    Last week saw Russia’s Gazprom Neft, the country’s third biggest oil company by output and the oil arm of state gas giant Gazprom, ship its first cargo of oil produced in the Arctic to China via the Northern Sea Route (NSR). This shipment East adds to its existing Western exports via the NSR to Europe. According to Gazprom Neft, it took 47 days to deliver a full cargo of 144,000 tonnes of sweet, light Novy Port oil from the Yamal peninsula developments to the Chinese port of Yantai on the Bohai Sea, from Russia's north-western city of Murmansk. “Successful experience in the sale of Arctic oil in the European market and an in-depth insight of Asia-Pacific markets allow Gazprom Neft to offer Novy Port oil with a unique year-round logistics scheme to Asian partners,” said Gazprom Neft’s deputy director general for logistics, processing and sales, Anatoly Cherner, last week.

    V US v oblastech ohrozenych aktivni hurikanovou sezonou prudce roste nakazenych koronavirem

    Hurricane-prone states are experiencing some of the nation’s sharpest increases in COVID-19 infections, raising fears that a major storm will have deadly consequences if people in its path refuse to evacuate to avoid contagion.
    The number of infections nationwide has more than doubled since the start of hurricane season on June 1, passing 3.8 million yesterday.
    The increase has been especially dramatic in Southeastern states on the Atlantic and Gulf coasts, federal data shows, leaving hospitals strained and people potentially wary of finding shelter during a hurricane or staying with friends or relatives.
    A surge in COVID-19 cases also could complicate hurricane recovery by prompting the Federal Emergency Management Agency to avoid sending disaster relief workers into pandemic hot spots.

    Klimatická zmena
    V roku 2020 bola priemerná teplota povrchu oceánov zatiaľ rekordne teplá v 5 mesiacoch zo šiestich na severnej pologuli, len v Januári bola 2. najvyššia (po Januári 2016). Neprekvapuje teda, že za 1. polrok 2020 je priemerná teplota povrchu oceánov na severnej pologuli výrazne najvyššia od roku 1850 (keď začali systematické merania). Na južnej pologuli je situácia trochu odlišná, ako vidíme z priloženého grafu. Je celkom zrejmé, že priemerná teplota povrchu oceánov je ovplyvnená javmi ElNiňo a LaNiňa (tu je to reprezentované 3-mesačnými priemermi Oceánického Niňo Indexu - ONI). Od roku 2003 ale sledujeme výrazný ročný chod odchýlok priemernej teploty oceánov na severnej pologuli a od roku 2016 menej výrazný aj na južnej pologuli, čo je neklamný dôkaz vplyvu globálnej klimatickej zmeny na teplotné pomery polárnych oblastí.
