    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.

    Carbon capture marches toward practical use | Science
    https://science.sciencemag.org/content/371/6536/1300?rss=1

    Today's most popular approach, which uses chemicals called amines dissolved in water to for capture CO2, is too expensive for widespread use. But researchers are now developing a new generation of chemical CO2 traps, including an organic solvent, which was shown this month to reduce the cost by nearly 20%. When existing U.S. tax credits are added to the mix, carbon capture is nearing commercial viability.

    Having it all: Protecting biodiversity, carbon capture, and fish stocks | Ars Technica
    https://arstechnica.com/science/2021/03/how-to-optimize-protecting-the-ocean/

    The first of the benefits they looked at is biodiversity. The second is an area's benefits to fish stock—its ability to enable more fish to spawn. According to the Food and Agriculture Organization (FAO), 90 percent of marine fish stocks in 2018 are either depleted, overexploited, or fully exploited. The third quality is the parcel's capacity to sequester carbon in its sediment. Some of the team's researchers previously mapped the carbon sequestration potential of different parts of the ocean, and they found that ocean sediments can sequester more than twice the amount that terrestrial soils can.

    ...

    Hypothetically, if the world's governments wanted to maximize for biodiversity, they would need a strategically located 21 percent of the ocean placed under marine protected areas. This would raise the average protection of endangered and critically endangered species from their current rates of 1.5 and 1.1 percent to 82 and 87 percent, respectively, the paper notes. This form of optimization would, coincidentally, protect 89 percent of at-risk carbon sequestering areas in the oceans.

    Los Angeles has a plan for 98% clean power by 2030.
    100% clean by 2035

    "The path forward for the next decade is clear, NREL found: Build solar farms, wind turbines and batteries as fast as possible. Get solar panels on rooftops, electric cars in garages and electric heat pumps in homes. And invest in energy efficiency and “demand response” programs that pay people to use electricity during times of day when solar and wind power are plentiful."

    Průkopník v Evropě: rakouská vláda otevírá energetiku pro energetická společenství
    https://www.obnovitelne.cz/...-evrope-rakouska-vlada-otevira-energetiku-pro-energeticka-spolecenstvi

    Rakouská vláda ve středu 17. března 2021 schválila návrh zákona o obnovitelných zdrojích energie, který vytvoří právní a finanční impuls pro přechod na 100% elektřinu pouze ze slunce, větru, vody a biomasy. Do rozšíření obnovitelných zdrojů bude každý rok investována jedna miliarda EUR. Nyní bude návrh zákona schvalovat parlament.

    Vláda kancléře Sebastiana Kurze dostála svým předvolebním slibům. Na sestavení legislativních změn k zajištění přechodu na elektřinu 100 % zásobovanou energií z obnovitelných zdrojů a nastavení podmínek pro vznik energetických komunit jí stačil pouhý rok. Ve srovnání s naším jižním sousedem česká vláda hledá cestu k podpoře obnovitelných zdrojů několik let. V Česku se například stále nedaří najít shodu na systému podpory nových projektů obnovitelných zdrojů formou aukcí.

    Australia set to reach carbon net-zero target a decade sooner than others
    https://www.energymatters.com.au/...set-to-reach-carbon-net-zero-target-a-decade-sooner-than-others/

    This was ratified in the 2015 United Nations Paris Agreement, which saw 195 countries sign up and pledge their commitment towards reaching that target by 2050. This includes Australia; although the way things are tracking, we could achieve carbon net-zero emissions in 2040 – a decade ahead of the global target.

    Australia added about seven gigawatts of renewable energy in 2020 – a record volume –  and would need to double that to 14GW to reach the target. Meeting this target would wipe out 80 per cent of our emissions, all coming from fossil fuels and allow us to be carbon neutral.

    ...

    One single project is already set to smash our annual record with sprawling Australia–ASEAN Power Link project in the Northern Territory set to deliver a 10GW solar farm.

    There are also 95 projects set to commence construction or completion in the near future that will deliver another 11.209GW of renewable power. Add to that the 10.531GW of projects that have not yet reached financial close or be commissioned, and we are looking at an enormous spike in the volume of solar power being installed across Australia.

    Wind power is also set to boom, with 2021 predicted to be the biggest on record. It is one of the fastest-growing sources of energy globally, and five major projects are going ahead in Australia that will deliver 6.93GW of power in 2021 and 2022.

    Australia already has 20.21GW of solar PV systems installed across 2.66 million homes and business, and this number is set to spike as well. There were 333,978 installations in 2020 –  despite the global COVID-19 pandemic – which added 2.6 GW of capacity to the network. That number is set to rise year on year as well.

    Konec uhlí štěpí českou vládu. Prodloužení odchodu se ale může prodražit - iDNES.cz
    https://www.idnes.cz/ekonomika/domaci/uhli-ekologie-konec-politika.A210323_202507_ekonomika_kou

    Je to přes čtvrt roku, kdy Uhelná komise doporučila skončit s využíváním uhlí v Česku do roku 2038. Jenže na vládě se schvalování tohoto termínu zaseklo. Mezi ministry nyní převažuje názor, že by bylo lepší odstavit poslední uhelný zdroj nejpozději v roce 2033. Toto datum podporuje osm ze 14 členů vlády. Z odborné debaty, kdy se Česko obejde bez spalování uhlí v ­elektrárnách a teplárnách, se však stala veskrze politická věc.

    Clean Planet Energy Makes Fuels For Airplanes & Ships From Non-Recyclable Plastics
    https://cleantechnica.com/...et-energy-makes-fuels-for-airplanes-ships-from-non-recyclable-plastics/

    Its goal is to convert more than 1 million tons of non-recyclable plastic waste a year into clean burning fuels and other low carbon products. “Clean Planet’s liquid fuels, produced using our propriety upgrading process, provide at least a 75% reduction in CO2e emissions compared to traditional fossil fuels,” the company says.

    Evropa je přesně v 1/2 cesty k odstavení všech uhelných elektráren. 162. ze 324 celkem se stane britská West Burton A (v srpnu 2022), oznámil její provozovatel EDF. Mimochodem v USA zbývá 191 z původních 530 uhelných elektráren, takže tam už jsou na 2/3.

    Nejde totiž jen o to, že hladina oceánů v posledních dvou dekádách stoupá, a to zprůměrovaným tempem 2,5 milimetrů za rok. Ta největší města a rozrůstající se metropole na pobřeží totiž současně klesají a propadají se. Tempem přibližně 8-10 milimetrů ročně, v extrému tedy čtyřikrát rychleji

    ...

    Ptát se můžeme 33 milionů obyvatel aglomerace Tokia, které stojí stále na tom samém pobřeží, ale momentálně 4 metry níže než na počátku 20. století
