    TUHOKlimaticka zmena / If the fracturing of our once stable climate doesn’t terrify you, then you don’t fully understand it


    "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.

    Jailed for 51 weeks for protesting? Britain is becoming a police state by stealth | George Monbiot | The Guardian
    https://www.theguardian.com/commentisfree/2021/dec/01/imprisoned-51-weeks-protesting-britain-police-state

    Priti Patel, the home secretary, shoved 18 extra pages into the bill after it had passed through the Commons, and after the second reading in the House of Lords. It looks like a deliberate ploy to avoid effective parliamentary scrutiny. Yet in most of the media there’s a resounding silence.

    Among the new amendments are measures that would ban protesters from attaching themselves to another person, to an object, or to land. Not only would they make locking on – a crucial tool of protest the world over – illegal, but they are so loosely drafted that they could apply to anyone holding on to anything, on pain of up to 51 weeks’ imprisonment.

    Vast networks of underground fungi – the “circulatory system of the planet” – are to be mapped for the first time, in an attempt to protect them from damage and improve their ability to absorb and store carbon dioxide.
    Fungi use carbon to build networks in the soil, which connect to plant roots and act as nutrient “highways”, exchanging carbon from plant roots for nutrients. For instance, some fungi are known to supply 80% of phosphorus to their host plants.
    Underground fungal networks can extend for many miles but are rarely noticed, though trillions of miles of them are thought to exist around the world. These fungi are vital to the biodiversity of soils and soil fertility, but little is known about them.

    varoufakis o(promarnene) sanci, kterou koronavirova krize predstavovala

    Pandemie nabídla Evropě příležitost zformulovat věrohodný plán dobře zafinancovaného přechodu k Zelené energetické unii. Pokud bychom zavedli evropské dluhopisy, mohla se Evropská centrální banka vymanit z očistce permanentního maskování bankrotu a vyhlásit, že bude krýt jen dluhopisy vydané Evropskou investiční bankou na financování Zelené energetické unie. To se ale nestalo. Evropa tu skutečně propásla příležitost vést svět silou svého příkladu od závislosti na fosilních palivech.

    Evropané v tom samozřejmě ale nejedou sami. Zatímco americký prezident Joe Biden mířil do Glasgow, Kongres USA v jednom ze svých charakteristicky zkorumpovaných politických rozhodnutí vypreparoval jeho už beztak značně osekané zelené plány ze zcela „hnědého“ infrastrukturního zákona, a změnu klimatu tak uložil k ledu.

    New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency - Green Car Congress
    https://www.greencarcongress.com/2021/11/20211116-electrocat.html

    The electrocatalytic conversion of CO2 using renewable energy could establish a climate-neutral, artificial carbon cycle. Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO2. These could then be burned as needed. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport.

    Now, researchers in China have developed a new electrocatalyst that yields ethanol, acetone, and n-butanol as major products with a total C2-4 faradaic efficiency of about 49 % at −0.8 V vs. reversible hydrogen electrode (RHE), which can be maintained for at least 3 months. A paper on the development is published in the journal Angewandte Chemie.

    Wildfires are erasing Western forests. Climate change is making it permanent. | Grist
    https://grist.org/climate/climate-change-forest-loss/

    Now that the winter has cooled the 2021 fire season, scientists are looking at the big burn scars across the West with the grim understanding that, in some places, the pine and Douglas fir forests will not return. 

    The driving force here is that the rising global temperature is wiping out seedlings. In many spots around the U.S. West, summer temperatures are already high enough to cook young trees before they can develop thick protective bark. Others have become so dry that seedlings shrivel before their roots can grow deep enough to reach groundwater. Both circumstances can thwart forest regeneration. Mature trees can survive in these areas long after they stop reproducing. But when fires wipe out these forests and seedings can’t get a foothold, they are replaced with grasses and dense brush. 

    Climate change has already shifted biomes. Intense fires simply clear away the last vestiges of the old regime.

    Pesticides 'cost double the amount they yield', study finds
    https://euobserver.com/climate/153671

    According to a study published on Tuesday (30 November), the cost of pesticides may far outweigh the economic benefits.

    The Bureau for the Appraisal of Social Impacts for Citizen Information (BASIC), a Paris-based NGO, found pesticide producers cost the EU €2.3bn in subsidies.

    At the same time, the sector makes about €900m in profits, and the study argues this is not an efficient way of spending agricultural funds.

    "Tripling organic farms by 2030 would cost €1.85bn per year - less than the annual subsidies being spent on pesticides," a group of researchers connected to BASIC wrote.

    Future climate change shaped by inter-model differences in Atlantic meridional overturning circulation response | Nature Communications
    https://www.nature.com/articles/s41467-021-24015-w

    In climate model simulations of future climate change, the Atlantic Meridional Overturning Circulation (AMOC) is projected to decline. However, the impacts of this decline, relative to other changes, remain to be identified. Here we address this problem by analyzing 30 idealized abrupt-4xCO2 climate model simulations. We find that in models with larger AMOC decline, there is a minimum warming in the North Atlantic, a southward displacement of the Inter-tropical Convergence Zone, and a poleward shift of the mid-latitude jet. The changes in the models with smaller AMOC decline are drastically different: there is a relatively larger warming in the North Atlantic, the precipitation response exhibits a wet-get-wetter, dry-get-drier pattern, and there are smaller displacements of the mid-latitude jet. Our study indicates that the AMOC is a major source of inter-model uncertainty, and continued observational efforts are needed to constrain the AMOC response in future climate change.

    The recent expansion of Atlantic waters into the Arctic Ocean represents undisputable evidence of the rapid changes occurring in this region. Understanding the past variability of this “Atlantification” is thus crucial in providing a longer perspective on the modern Arctic changes. Here, we reconstruct the history of Atlantification along the eastern Fram Strait during the past 800 years using precisely dated paleoceanographic records based on organic biomarkers and benthic foraminiferal data. Our results show rapid changes in water mass properties that commenced in the early 20th century—several decades before the documented Atlantification by instrumental records. Comparison with regional records suggests a poleward expansion of subtropical waters since the end of the Little Ice Age in response to a rapid hydrographic reorganization in the North Atlantic. Understanding of this mechanism will require further investigations using climate model simulations.

    Vybijeme chovy. Na každém praseti tratíme tisíc korun, tvrdí chovatelé - Seznam Zprávy
    https://www.seznamzpravy.cz/clanek/ekonomika-firmy-vybijeme-chovy-na-kazdem-kilogramu-tratime-tisic-korun-tvrdi-chovatele-182099

    Říká se, že zemědělci neustále brečí. Situace je ale vážná. Vysloveně zvažujeme, že budeme zavírat některé chovy brojlerů i prasat. Není možné, abychom takto dál fungovali,“ uvedl Zdeněk Mlázovský, místopředseda představenstva společnosti Proagro Nymburk, která se zabývá rostlinnou produkcí a chovem drůbeže, jatečných prasat a nosnic.

    „Potřebovali bychom prodávat vejce o 20 až 30 haléřů dráž, brojlery až o osm korun a skoro se to bojím říct, ale vepřové až o 15 korun dráž,“ dodal.

    Podle něj je sice dlouhodobě složité promítnout výrobní náklady do prodejních cen živočišných produktů, ale v poslední době je situace neudržitelná. „Je to extrém, není už úplně možné, abychom dokázali náklady snížit a dostali se do plusových čísel,“ upozornil.

    Za pohonné hmoty podnik platí až o 30 procent víc, za krmiva desítky procent, obaly o sedm procent a za elektřinu a plyn, které prodražují chovy kuřat, jimž se musí zatápět, troj- až čtyřnásobek
