    GOJATLA: hm toto mi nejako nesedi s narativom, ktory prezentovala tesla, ze sa lithium da vytazit z hliny v Nevade :)
    For the cases of copper and manganese the depletion is mainly due to the demand from the rest of the economy,” but most lithium demand “is for EV batteries,” and this alone “depletes its estimated global reserves.”

    Capitalism Will Ruin the Earth By 2050, Scientists Say
    https://www.vice.com/en/article/v7m48d/capitalism-will-ruin-the-earth-by-2050-scientists-say
    On the first option, scientists backed by the European Union’s Horizon 2020 research and innovation program have concluded that capitalism-as-we-know-it cannot support a successful clean energy transition.

    Not only that, but capitalism is on track to lead the world into mineral shortages and supply bottlenecks that could cut short efforts to decarbonize transport systems, guaranteeing dangerous climate change.

    The new study published in the journal Energy Strategy Reviews finds that electrifying our cars, trucks and trains so that they run on renewable energy is only viable if we reduce the endlessly growing levels of consumption in industrial societies. That, effectively, means fundamentally transforming the very sinews of capitalism.

    The real story of the day
    https://gretathunberg.medium.com/the-real-story-of-the-day-3b04f49f5025

    Today, eleven months after the European Parliament declared a climate emergency, the very same parliament voted to go ahead with an agricultural policy that — in summary — fuels ecological destruction with almost 400 billion euros. Hundreds of thousands of tweets using #VoteThisCAPdown asking the MEPs to intervene didn’t convince enough MEPs to flip this.

    ...

    We ask the people to stay with us and keep pushing. We ask the ones in power to stop pretending they care — or to get going in case they mean it. And we ask the media to wake up, to rise up to their responsibility. This result happened due to that media decided to stay silent, decided not to question proposals, not to challenge leaders, not to intervene, not to inform the public. And if the media continues down this dangerous road, they will lose their credibility among countless young people. And this is something we can not allow to happen as there is no future for democracy without a strong, independent free press.
    One hundred and fourteen weeks have passed since our first school strike. And it’s still up to us.

    ne-prekvapeni

    Dojednáno jest. Pozice Europarlamentu ke Společné zemědělské politice schválená. Je hodně špatná a od mojí středeční analýzy se ještě trochu zhoršila. Jediné pozitivum je zastropování dotací na jeden podnik, které jsou však příliš vysoko a navíc není jisté jestli projdou trialogem (Rada tam má jenom dobrovolné stropy). Text k tomu budu mít buď dnes večer nebo až zítra (vzhledem k Prymulagate máme jiné priority).
    Mrzí mě to

    Ecology: Western Sahara and Sahel tree-count exceeds expectations | Nature | Nature Research
    http://www.natureasia.com/en/research/highlight/13477

    More than 1.8 billion individual trees can be found in the West African Sahara, Sahel and sub-humid zone, according to a report in Nature this week. A combination of high-resolution satellite imaging and deep learning has revealed a relatively high density of tree coverage for this arid area.

    Each quarter, Zeke Hausfather runs through all the latest climate data and produces a “state of the climate” report for Carbon Brief. His latest report, published this morning, concludes that “it is now more likely than not that 2020 will be the warmest year for the Earth’s surface since reliable records began in the mid-1800s” (recent decades show in chart above).
    This is already a striking statement. But what makes it more so is that 2020 will lack any major El Niño event – a factor that has contributed to most prior record warm years, including the current record-setting year of 2016.
    Furthermore, despite the impact of the global Covid-19 lockdowns, the first nine months of the year saw record concentrations of major greenhouse gases – CO2, methane, and nitrous oxide – in the atmosphere. Arctic sea ice extent has also been at record low levels for much of the year and the summer minimum recently clocked in as the second lowest on record after 2012.
    We must now wait for the year’s final three months of data to come in to know if 2020 will break the current record.

    Fences dub ecological winners and losers, shape ecosystems
    https://www.anthropocenemagazine.org/...e-sun-but-still-dont-understand-their-effects-here-on-earth/


    In a recent paper in BioScience, a group of experts argues that it’s time for conservationists to start seriously investigating the many ways in which fences shape ecosystems— so that we can make better decisions about where (and whether) to build them. By analyzing hundreds of previous studies, they hope to lay a framework for this area of study, which they and others call “fence ecology.”

    Although fences are “often framed as a management tool,” the authors write, they are actually “a globally significant ecological feature.” If you put the world’s fences end to end, they would stretch at least as far as the distance between the Earth and the sun—much farther than the length of the world’s combined roads. And “they’re proliferating very rapidly,” with new fences added much more frequently than old ones deteriorate or are taken down,



    Fence Ecology: Frameworks for Understanding the Ecological Effects of Fences
    https://academic.oup.com/bioscience/advance-article/doi/10.1093/biosci/biaa103/5908036

    "Most of the time, fences produce more losers than winners,” Dr. McInturff says. Often, these winners are generalists that can handle disturbed areas—in other words, the same ones that survive other types of habitat disruption. More sensitive species tend to lose out. In some cases, fences curtail so many different species that whole ecosystems begin to collapse.

    Alarm as Arctic sea ice not yet freezing at latest date on record | Arctic | The Guardian
    https://amp.theguardian.com/.../22/alarm-as-arctic-sea-ice-not-yet-freezing-at-latest-date-on-record

    For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October.

    The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region.

    Ocean temperatures in the area recently climbed to more than 5C above average, following a record breaking heatwave and the unusually early decline of last winter’s sea ice.

    The trapped heat takes a long time to dissipate into the atmosphere, even at this time of the year when the sun creeps above the horizon for little more than an hour or two each day.
