    World's first wind turbine with recyclable blades is up and spinning
    https://electrek.co/2022/08/02/worlds-first-wind-turbine-with-recyclable-blades-is-up-and-spinning/

    Separating the resin, fiberglass, and wood, among others, is achieved through using a mild acid solution. The materials can then go into the circular economy, creating new products like suitcases or flat-screen casings without the need to call on more raw resources.

    Druhy dil serie longreadu o klimatickych dezinformacich je venku. Tentokrat o formovani vedecke shody na ohrivajicim vlivu spalovani fosilnich paliv

    Na tom, že za ohřívání klimatu může spalování fosilních paliv je dlouhodobá, jasná a přesvědčivá shoda v odborné komunitě již velmi dlouhou dobu. Bohužel je to zároveň něco, co laická veřejnost ne vždy chápe. Zatímco analýza vědeckých prací ukazuje, že naprosto drtivá většina vědecké literatury se shoduje na tom, že za současnou vlnu oteplení může spalování fosilních paliv, veřejnost o této široké shodě často neví a domnívá se, že vědci nemají o příčinách oteplování stále jasno. Navíc mezi ty nejméně chápavé patří ekonomové a politici. A nejen to, ale s tím, jak pro tuto teorii přibývalo důkazů a shoda se rozšiřovala, začalo docházet k názorovému „protipohybu“ ve veřejné a politické sféře, která naopak toto téma v řadě zemí začala vnímat jako stále kontroverznější a zpolitizovanější.
    Pojďme se tedy podívat na dějiny utváření vědeckého konsenzu. Odhalí se před námi fascinující obor s více než stoletou historií, se spoustou zvláštních zákoutí, kontroverzí a pozoruhodných objevů.

    RADIQAL: v celkovejch proporcich private jety delaj asi 0.004 procenta dle rychlyho orientacniho propoctu, ale zase proporcne jde o podobne uzkou skupinu lidi (max stovky tisic lidi) ... takze ten graf tohle v tom extremu akorat ukazuje

    During the past year, private jet travel has emitted over 26 megatons of CO2, 1 megaton of CH4, and 0.22 megatons of N2O. This equates to a total of approximately 184 megatons of CO2-equivalents. This figure is roughly equivalent to the reduction in energy-related emissions in 2019 that the U.S. strived to achieve (EIA, 2020). The level of increase in emissions from pre-pandemic levels to 2021 were also significant. In 2019, private jet travel accounted for only 6.3% of total aviation related emissions in the U.S. This share was relatively stable from 2014 to 2019; however, the pandemic induced boom coupled with the decline in commercial travel has resulted in private jet travel growing its share of emissions from 6.3 to 7.9% of total commercial plus private aviation emissions - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8888033/#s0045

    The global aviation industry produces around 2.1% of all human-induced carbon dioxide (CO2) emissions - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8888033/#s0045

    Total greenhouse gas emissions reached 40.8 Gt of CO2 equivalent (CO2eq) in 2021 - https://www.iea.org/reports/global-energy-review-co2-emissions-in-2021-2

    Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for climate change, such potential futures are poorly understood. Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. Analyzing the mechanisms for these extreme consequences could help galvanize action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the likelihood of extreme climate change, discuss why understanding bad-to-worst cases is vital, articulate reasons for concern about catastrophic outcomes, define key terms, and put forward a research agenda. The proposed agenda covers four main questions: 1) What is the potential for climate change to drive mass extinction events? 2) What are the mechanisms that could result in human mass mortality and morbidity? 3) What are human societies' vulnerabilities to climate-triggered risk cascades, such as from conflict, political instability, and systemic financial risk? 4) How can these multiple strands of evidence—together with other global dangers—be usefully synthesized into an “integrated catastrophe assessment”? It is time for the scientific community to grapple with the challenge of better understanding catastrophic climate change.

    RADIQAL: offsetovanie vo forme vysadby stromov zas tolko energie nespotrebuje, jako jo bolia ta potom vecer ruky a mozno si nalozis na obed vepro-knedlo-zelo miesto lahkeho letneho salatu z lokalnych surovin, ale co do nejakej skonzumovanej fosilnej energie to je zanedbatelne, takisto ked si bohaty cech miesto letenky na maledivy necha nainstalovat solary na strechu, tak zacal offsetovat, tam uz ta vstupna energia nejaka je, ale uz 5 rokov dozadu sme videli studie, ktore ukazovali ze panel sa energeticky zaplati za 4-5 rokov, pri dnesnych ucinnostiach to bude aj polovica

    DZODZO: Milion doláčů je směšný. Miliarda taky. Offsetovanie je dead end, protože samo o sobě spotřebovává velké množství energie.

    @TADEAS: tezko rict, kde je hranice “okázalé spotřeby” a kde se do těch multimiliard počítaj “běžný” businessy. (AB na jednu stranu drtí českó krajinu subvencovanejma monokultura, na druhé straně peče (kolik?) 50% našeho chleba).
