    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.

    Aha, tak to jste mě uklidnily. :) Já už myslel, že bude nějaká apokalypsa v důsledku nedostatku zdrojů nebo potravin či co. Ale vyšší vzdělanost, emancipace žen a v důsledku nižší porodnost, bude fajn. ;)

    Vzdelani a emancipace zen (vysoka skola posouva porodnost na pozdejc a kariera omezuje pocet deti na zenu). Tohle vsechno se udalo vsude na svete kde se zvysila zivotni uroven a ta se ted zvysuje i v jihovychodni Azii a v Africe

    Rust se zpomali (ted kolem 80M rocne), chvili bude plateau a pak to bude pozvolna klesat, ale to uz mluvime o letech 2100 a vejs

    JIMIQ: A co se stane potom, když se má populace v růstu zastavit nebo začít klesat? Celou dobu růst až k 10 mld. a pak najednou stop? Je na to nějaký scénář?

    zajmavej clanek. bejvalej exec Blackrocku o klimatu, trhu a zelenejch investicich. ve zkratce rika, ze bez carbon tax to nepujde/nikam nepovede. nevim jak moc s tim souhlasit, protoze zanedbava fakt, ze na renewables se da vydelat a bude lip, v sirsim kontextu ale bude mit pravdu

    blackrock na to reaguje, ze to tak neni (zmenili strategii z fosil na green investments, musi to hajit) a zaroven dodava, ze opravdu statni regulace by pomohly vic/rychleji nez freemarket, takze s nim vlastne souhlasi :)

    $5.4 B Project Will be World's Largest Green Hydrogen Producer in 2025
    https://cleantechnica.com/...lion-project-aims-to-be-worlds-largest-green-hydrogen-producer-in-2025/

    Enegix Energy is moving forward with plans to build a $5.4 billion facility off the coast of Brazil called Base One. And that’s news because the company claims that Base One will be the world’s biggest individual CO2 reducer by generating more than 600 million kg of green hydrogen per year by the time it’s fully operational in 2025.

    Australian scientists achieve breakthrough with renewably powered carbon capture – pv magazine International
    https://www.pv-magazine.com/...-scientists-remarkable-renewably-powered-carbon-capture-breakthrough/

    Australian scientists have achieved a new breakthrough in carbon capture and storage. Their novel electrochemical process can store carbon dioxide in water with the power of solar or wind, while also producing by-products such as green hydrogen and calcium carbonate – perhaps the key to decarbonizing the cement industry.

    Researchers from the Queensland University of Technology have made a remarkable breakthrough with the development of an electrochemical process in which carbon dioxide is captured from the air and stored in water as a non-toxic calcium carbonate (chalk) in a renewably powered process that could also produce green hydrogen and decarbonize the cement industry. 

    ...

    We found we could use seawater once it had been treated to remove sulphates. To do this we first precipitated calcium sulphate or gypsum, another building material, and then carried out the same process to successfully turn CO2 into calcium carbonate, thus providing proof of concept of a circular carbon economy,” O’Mullane said. “Next, the hydrogen evolution reaction during electrolysis ensured that the electrode was continually renewed to keep the electrochemical reaction going while also generating another valuable product, green hydrogen. This means if this electrolysis process is powered by renewable electricity, we are producing green hydrogen alongside the calcium carbonate (CaCO3).”
