    I’m struggling with “systems thinking” /-er; the word feels awkward at best, or distancing / arrogant often. But what other noun is there?

    Most people don’t think in this way, it’s not at all intuitive in modern civilization, where success follows narrow expertise & reductionism
    Regular reminder that these aren’t just academic pursuits; the difference between systems & linear thinking this year is measured in hundreds of thousands of lives, & many more affected. A stunning failure of western language, culture & education,

    What to learn from it, & how-/- without losing trust in people’s judgement remains a struggle even after almost a year now.

    Climate, same story. Have we learned from the past 50 years of reality denial? People seem to think that they can take on either climate or growth, but not but at the same time.

    Dear all, you’re confusing symptom with cause which of course is the very shape of the problem

    Best example: carbon law in Rockström et al 2017; but this is the rockbed of climate science & activism too, including IPCC

    carbon emissions irreversibly approaching zero?

    have y’all ever thought, seriously, what that would mean?

    Spoiler: a system whose internal structure compels it to grow will not stop growing just because *melting glaciers*

    Lack of access to energy resources will do the trick, but that’s not what we want. Gotta work harder if we hope to rebuild systems that can exist without growth

    Fascinating, from a systems view, activists are then *how* the system speaks if it is not held together by a strong sense of trust & ethical bonds which of course we’re unraveling at astonishing speed

    As ever, covid as climate not only in fast (that’s just human perception) but in *with feedbacks and without long delays, so we could learn

    Jen pro zajimavost, vyjadreni predsedkyne AV CR. To vyjadreni ktere ma smerem ke klimatickym zmenam, je to v zasade nazor ktery jsem mel pred jeste 2 lety. Je to vysoce rozsireny nazor u technickych / life-science vedcu napric kontinenty - vyjma pochopitelne klimatologu. Na tom lze krasne demonstrovat jak lze (kdyz jsou penize a cas) zacilit to vrstveni informaci na jakoukoliv socialni ci kulturni skupinu. Vzdelani nehraje roli.

    Klimatickou změnu pomohou ustát cílené genetické modifikace, říká šéfka AV ČR - Seznam Zprávy
    https://www.seznamzpravy.cz/...ope-pomohou-zmenu-klimatu-zvladnout-gmo-rika-predsedkyne-av-cr-132211
    Je velmi naivní si myslet, že svět, jaký máme teď, tady byl pořád. Svět se neustále mění a mění se i klima. Základní otázkou je, čím nebo jak k tomu přispívá člověk. Zda jde především o produkci kysličníku uhličitého a třeba i metanu a dalších skleníkových plynů. Není sice pochyb, že jejich nárůst je signifikantní a je nejrychlejší od doby, kdy ho umíme měřit, ale jsou to zatím nepatrná čísla (v atmosféře v řádech ppm). Dají se udělat nějaké predikce, ale ty lze dělat jen na základě současných znalostí a současného stavu.

    Sasa Vondra vydal knizku o klimatu .]]

    Alexandr Vondra s dalšími autory vydal knihu, v níž se snaží definovat konzervativní ekologickou politiku. Výsledkem je text, v němž pravicoví aktéři soustavně a mnohde explicitně legitimizují agendu ekologického a klimatického hnutí.

    California Water Futures Begin Trading Amid Fear of Scarcity
    https://www.bloomberg.com/...020-12-06/water-futures-to-start-trading-amid-growing-fears-of-scarcity

    The contracts, a first of their kind in the U.S., were announced in September as heat and wildfires ravaged the U.S. West Coast and as California was emerging from an eight-year drought. They are meant to serve both as a hedge for big water consumers, such as almond farmers and electric utilities, against water prices fluctuations as well a scarcity gauge for investors worldwide.

    “Climate change, droughts, population growth, and pollution are likely to make water scarcity issues and pricing a hot topic for years to come,” said RBC Capital Markets managing director and analyst Deane Dray. “We are definitely going to watch how this new water futures contract develops.”

    More Green Hydrogen In USA - Netherlands Offshore Wind Scheme
    https://cleantechnica.com/2020/12/07/more-green-hydrogen-in-us-netherlands-offshore-wind-hookup/

    The partners certainly don’t intend to let any grass grow under their feet. They aim to complete a feasibility study sometime soon and begin work on project development in 2021, with an eye on reaching a capacity of 1 gigawatt (GW) for electrolysis in 2027.

    Other milestones cited by Equinor include 4 GW by 2030, jumping up to 10 or more GW by 2040. That roadmap provides for 0.4 million tonnes of green hydrogen in 2030 and 1 million tonnes by 2040, which is expected to abate anywhere from 8 to 10 million tonnes of CO2 emissions.

    JIMIQ: :D jako obvykle...

    IEA says “it’s not a prediction/forecast and that everybody is using it that way is not their problem. It’s a scenario assuming current policies are kept and no new policies are added. Many people have pointed out that they are still very wrong if you try to account for that but no reactions from IEA to that as far as I can tell.”

    He adds that “the discrepancy basically implies that every year loads of unplanned subsidies are added while that is not always the case but so far I know of no reaction to those criticisms either. So it boils down to: it’s not a forecast and any error you find must be attributed to that. And no you cannot see how the model works.”

    SHEFIK: je to priklad logistickeho rustu (v tomto pripade Wh/$), totez plati i pro FVE nebo vetrniku. Hezky o tom pise Smil tady https://www.goodreads.com/book/show/44512537-growth . Tady v teto projekci je hezky videt ten logaritmickej dobeh (https://www.nrel.gov/docs/fy19osti/73222.pdf ). Drive jsem tu tak nahrubo pocital, ze aby se baterie + FVE vyplatila, musely by byt v nasich podminkach levnejsi okolo 40%. Jak je videt, median te predikce je nekde okolo 50% zlevneni do 2030, takze ja osobne pocitam pro FVE uz s baterii. Ne ted, ale za 5-10 let uz to bude zajimavy. Mohlo by to pokryt velkou cast spotreby, o tom zadna.
