    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.

    BROZKEFF: Jednou stranou je, jak pises, zflexibilnit distribuci (pomoci baterii atp), druhou moznosti je zflexibilnit poptavku. Nekteri dodavatele fotovoltaiky (napr Fronius) maji uz celkem promakane systemy planovani spotreby - napr na zaklade predpovedi pocasi a naucenych vzorcu spotreby v tve domacnosti odlozi zapnutit pracky nebo mycky podle toho, kdy budes mit prebytky. Tohle lze dal kombinovat v ramci nejakeho blizkeho okoli do peer-to-peer siti. Zvykli jsme si s energii zachazet jak burani, protoze ji jako burani vyrabime. Kdyz prejdeme k inteligentnejsi vyrobe, musime pouzivat i mozek v jeji spotrebe.

    JIMIQ: MWpeak solaru a konstantní MW jadra nelze primo srovnavat. Pres zimu a v desti jedou solary na 0-10 % peak vykonu. Po tuto dobu je nutne mit konvencni zdroje a nebo si v lete nasyslit prebytek do nejakeho velkeho uloziste - napr vodiku, precerpavacek atd. Klicovy problem ted nejsou samotne solary, ale prave absence toho storage.

    Obří baterie v Česku dostanou šanci. Chystá se změna zákona - Seznam Zprávy
    https://www.seznamzpravy.cz/...nek/obri-baterie-v-cesku-dostanou-sanci-chysta-se-zmena-zakona-116985

    Hroutí se i další překážka: pro baterie chce od příštího roku zpřístupnit lukrativní trh s takzvanými podpůrnými službami státní společnost ČEPS. Ta platí elektrárnám či teplárnám za to, že jí pomáhají eliminovat výkyvy v napětí, a stabilizovat tak rozvodnou síť. Chystaný nový kodex ČEPS poprvé počítá s tím, že by stát mohl začít nakupovat podpůrné služby také od provozovatelů baterií, které nejsou součástí parních elektráren nebo tepláren.

    Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water
    Cambridge researchers develop standalone device that makes formic acid from sunlight, CO2 and water - Green Car Congress
    https://www.greencarcongress.com/2020/08/20200824-wang.html

    Researchers at the University of Cambridge, with colleagues at the University of Tokyo, have developed a standalone device that converts sunlight, carbon dioxide and water into formic acid, a carbon-neutral fuel, without requiring any additional components or electricity.

    The device is a significant step toward achieving artificial photosynthesis—a process mimicking the ability of plants to convert sunlight into energy. The device is based on an advanced ‘photosheet’ technology and converts sunlight, carbon dioxide and water into oxygen and formic acid—a storable fuel that can be either be used directly or be converted into hydrogen.

    Bird Fatalities Can Be Reduced By Painting Wind Turbine Blades
    https://cleantechnica.com/...0/08/31/bird-fatalities-can-be-reduced-by-painting-wind-turbine-blades/

    Wind power continues to be a viable source of renewable clean electricity production. Eventually, it could meet 35% of global power needs. 

    ...

    A relatively tiny portion of annual bird deaths are caused by wind power farms. (Cats kill far, far more each year, for example.) 

    ...
    How many wind turbines in your study had one blade painted black?

    Four turbines were painted; the experiment also included four neighboring control turbines.

    A 70% reduction in bird fatalities is a very significant decrease. Do you think it could be replicated at other wind power sites?

    Yes, it clearly can and should be replicated elsewhere to see to which extent the findings might be species- and site-specific. There is interest to do so in South Africa and in the Netherlands.

    Norwegians to Develop Next-Gen Turbine Installation Vessel | Offshore Wind
    https://www.offshorewind.biz/2020/08/31/norwegians-to-develop-next-gen-turbine-installation-vessel/

    The vessel will be able to install giant offshore wind turbines weighing more than 1,000 tones at a height of over 150 meters above sea level, the parties said.


    “We will jointly be developing one of the world’s most advanced vessels for installation of future offshore wind turbines, which are too large for the existing turbine installation fleet,” said Erik Haakonsholm, General Manager of Vard Group Offshore & Specialized Vessels.

    ...


    We currently have high expertise and solid revenues from oil and gas, and these resources are now dedicated to establish us as a leading player within the offshore wind space,” said Strømsnes

    Earth Overshoot Day 2020 - YouTube
    https://www.youtube.com/playlist?list=PLSVaEtHMi2FOdp3af6u9N44zXmJOW9BB9

    Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. COVID-19 has caused humanity's Ecological Footprint to contract, pushing the date of Earth Overshoot Day back more than three weeks compared to last year. The challenge of relaunching our economies presents countries with a unique chance to act on the future we want. On 20 August 2020 at 9:00 am CEST, the audience may join The Club of Rome and Global Footprint Network for an engaging online session streamed live on YouTube.

    This public event will combine live engagement with video messages from ‘green champions’ throughout Europe and will bring to life what it means in practice to 'build back better' post-COVID. Mathis Wackernagel (President of the Global Footprint Network) will kick off the Earth Overshoot Day campaign in Europe ahead of the global Earth Overshoot Day, which falls on Saturday 22 August this year.

    On this occasion, The Club of Rome and Potsdam Institute for Climate Impact Research (PIK) will present an updated Planetary Emergency Plan, making the case that the pandemic has highlighted our fragility and the profound links between disease, nature, climate and emissions, equity and justice, the finance sector and food systems. The report can be found here:

    http://clubofrome.org/wp-content/uploads/2020/08/COR-PEP_Aug2020_A4_16pp-digital-1.pdf

    The audience will have the opportunity to ask questions to our panelists throughout the event via the live chat box. For any remaining questions, there is time allocated for a short Q&A at the end of the programme.
