    JINDRICH: no hlavně na skládce suti... u nás jsou obrovské prostory typu výsypky popílku, které by se na to určitě hodily taky....

    u nás ale agrivoltaika není nějak vůbec legální, protože půdní fond a tak... ale pravda jsme poměrně dost na severu, takže to u nás nemá takový význam, jako třeba ve Francii, spíš bych to cpal na ty střechy supermarketů a logistických center, by default...

    JINDRICH: tak dobre ze pouzili brownfield

    "Na připojení do sítě tak čeká nevětší fotovoltaická elektrárna v Rakousku nacházející se přímo ve Vídni. S její stavbou začala Wien Energie na podzim roku 2020 na bývalé skládce suti v 22. vídeňském okrese. Na ploše o velikosti patnácti fotbalových hřišť má vzniknout elektrárna s výkonem 11,5 MW, která má zásobit až 15 200 domácností. Koncipována bude tak, že mimo výroby elektřiny bude sloužit pro chov 150 ovcí a jako zemědělská plocha. "

    90% Of Earth's Warming In 1971–2010 Happened In The Ocean
    https://cleantechnica.com/2021/01/19/90-of-earths-warming-1971-2010-happened-in-the-ocean/

    Sea levels are rising at the fastest rate in 3,000 years. From 2018 to 2019, the global sea level rose to 6.1 millimeters. Sure, a few millimeters doesn’t sound like a lot, until you hear that the average, since 1993, has been 3.2 millimeters per year. That means that last year we doubled the global average from the past twenty years!

    ...

    Since the Industrial Revolution, ocean acidity has increased by 30%. With large shellfish die-offs, the whole marine food chain is affected — not the best news for the multi-billion dollar fishing industry.

    ...

    With more heat in the atmosphere and warmer ocean surface temperatures, the world is experiencing an increase in the intensity and frequency of extreme weather events. For example, research suggests that the number of Category 4 and 5 hurricanes — characterized by higher wind speeds and more precipitation — is steadily increasing. To make matters worse, sea-level rise and a growing population along coastlines will exacerbate their impact.

    Gothenburg Partners With Volvo To Create A Climate-Neutral City
    https://cleantechnica.com/.../01/19/gothenburg-partners-with-volvo-to-create-a-climate-neutral-city/

    The Swedish city of Gothenburg is home to one of the largest and busiest ports in the world. Despite this, the city has set a rather ambitious climate goal for itself. With the help newly created urban zones that will serve as test beds for advanced sustainable technologies, Gothenburg plans to become a climate-neutral city by the year 2030. What’s more, they’ve enlisted Volvo to help.

    Vysokofrekvenční data jako proxy pro ekonomický vývoj

    Od začátku dubna měříme ekonomiku každý týden přes spotřebu elektřiny. Data jsou dostupná okamžitě na rozdíl od běžných makroekonomických statistik. Vysokofrekvenční data o vývoji spotřeby elektřiny očišťujeme o vliv počasí a využíváme je jako proxy pro odhad hospodářského vývoje při nedostupnosti základních makroekonomických statistik. Výsledky publikujeme v pravidelných aktualizacích tohoto blogu.

    Despite specific differences, the network of electrical signaling is present at almost each level of complexity, from unicellular bacteria and fungi to multi-cellular organisms like plants and animals. In unicellular organisms, cell-to-cell electrical signaling plays a key role in the reproduction and coordination of colony behavior. For example, bacteria Bacillus subtilis generates electrical signals mediated by potassium ion channels to direct motility in a biofilm of their own community, to stop reproducing bacteria on colony periphery, and to leave core cells with a sufficient nutrient supply (Humphries et al., 2017). A polarization and dynamic coordination of the electrical signals underlies also the ability of plant cell groups to proliferation, proper morphogenesis, regeneration and orientation (Filek et al., 2002; Yan et al., 2009; Nakajima et al., 2015). Similarly, the bioelectric network of each cell and the bioelectric gradients serve as a kind of pattern memory of animal tissues and organs (Durant et al., 2017). The environmental signals, physical (e.g., light, temperature, humidity, electric fields, wounding), chemical (e.g., nutrients and various substances), and biological (e.g., symbiosis, pathogenesis), can alter local and systemic electrical responses and modify cell division and growth. However, once the connectivity patterns of electrical signaling are disrupted, organisms can no longer follow appropriate morphogenetic and functional pathways (Szechyńska-Hebda et al., 2010; Karpiński et al., 2013; Nakajima et al., 2015).

    motivace

    Buildings and construction are responsible for 39% of anthropogenic carbon dioxide emissions – and a whopping 21% of those emissions come just from the making of steel and concrete.

    sand for concrete is controlled by sand mafias

    next decades:
    "It's like building a Manhattan every month for the next 40 years," said Ayres, borrowing a line from Bill Gates.


    Fungi

    produce co2, but also act as a store of carbon

    combining mycelium, the 'roots' of fungi, with agricultural waste such as straw

    Living fungi

    might behave as a self-healing material, simply re-growing if it becomes damaged. Second, mycelium networks are capable of information processing.

    The next major goal for the FUNGAR project is to build a small, freestanding building. They plan to pull that off within a year and then spend time monitoring it as it ages. It is crucial, says Ayres, to be able to monitor the living structure and see how it changes.

    Does carbon pricing reduce emissions? A review of ex-post analyses - IOPscience

    New paper alert! Does carbon pricing reduce emissions? A review of ex-post analyses. Short answer? Not so much. Of the policy tools in the carbon toolbox, c pricing is the tiny flathead screwdriver used to fix glasses.

    ...

    A meta-review of all the papers that look at the effects of #carbonpricing *after the fact*. Not models. Not predictions. A careful look at what has happened in the real world.

    First: *very* few studies that meet this criteria. Only 37 by my count. Vast majority (70%) study EU c pricing. There is SO MUCH WE DON’T KNOW.

    Second: Overall reductions are *really* small: 0-2% per yr. And this doesn’t factor in leakage or potential additionality problems w/ offsets. Leakage doesn’t appear to be an issue in Europe, but looks like a big prob in US (CA and RGGI).

    Third: On the whole, taxes do better on reductions than ETSs. Very important to consider as c pricing forges ahead

    Fourth: Limited effects + a lot of political controversy in big emitting countries like US, Australia, Canada, South Africa means we should really think hard abt whether this is a tool we should invest more time and resources in.

    Inner Mongolia pursues coal-led recovery, defying Beijing's climate goals

    Inner Mongolia went on an industrial permitting spree in 2020 that will lock in annual coal use about the size of Germany’s if fully realised, despite China tightening its climate targets at national level.
