    1177 B.C.: When Civilization Collapsed | Eric Cline
    https://youtu.be/M4LRHJlijVU


    Consider this, optimists. All the societies in the world can collapse simultaneously. It has happened before.

    In the 12th century BCE the great Bronze Age civilizations of the Mediterranean—all of them—suddenly fell apart. Their empires evaporated, their cities emptied out, their technologies disappeared, and famine ruled. Mycenae, Minos, Assyria, Hittites, Canaan, Cyprus—all gone. Even Egypt fell into a steep decline. The Bronze Age was over.

    The event should live in history as one of the great cautionary tales, but it hasn’t because its causes were considered a mystery. How can we know what to be cautious of? Eric Cline has taken on on the mystery. An archaeologist-historian at George Washington University, he is the author of "1177 B.C.: The Year Civilization Collapsed." The failure, he suggests, was systemic. The highly complex, richly interconnected system of the world tipped all at once into chaos.

    "1177 B.C.: When Civilization Collapsed" was given on January 11, 02016 as part of Long Now's Seminar series. The series was started in 02003 to build a compelling body of ideas about long-term thinking from some of the world's leading thinkers. The Seminars take place in San Francisco and are curated and hosted by Stewart Brand. To follow the talks, you can:

    Governments falling woefully short of Paris climate pledges, study finds | Climate change | The Guardian
    https://www.theguardian.com/science/2021/sep/15/governments-falling-short-paris-climate-pledges-study

    Every one of the world’s leading economies, including all the countries that make up the G20, is failing to meet commitments made in the landmark Paris agreement in order to stave off climate catastrophe, a damning new analysis has found.

    Less than two months before crucial United Nations climate talks take place in Scotland, none of the largest greenhouse gas emitting countries have made sufficient plans to lower pollution to meet what they agreed to in the 2015 Paris climate accord.

    Pardon, že zase ty debaty. ČT avizovala jako hlavní téma dnešní debaty s lídry z Vysočiny Zemědělství a životní prostředí, na webu pak: "Vyjádří se k několika problematikám. Mezi tématy bude zdraví prezidenta i pandemie covidu-19. Hlavní ale bude zemědělství a klima. Kromě ochrany životního prostředí se volební lídři budou věnovat například i elektromobilitě nebo extrémům počasí."
    Tak jsme se díval. A těžké zklamání. K tématu zemědělství (a lesnictví a vodárenství) se dostali až v závěrečné čtvrthodině a na životní prostředí a klima se dostalo v podobě, kdy se Witowská úplně blbě zeptá: "Andrej Babiš řekl pro iDNES - My nebudeme souhlasit, aby došlo k zákazu aut se spalovacími motory, my nemůžeme nadiktovat tady, co vymysleli zelený fanatici v Evropském parlamentu. Je tu někdo, kdo by s tímhle výrokem NESOUHLASIL?" A velké ticho a následně nějaké ty řeči proti zákazu, nedostatku elektřiny atd. Však posuďte sami.

    When scientists analyzed air samples trapped in drilled cores of Antarctica's ice, they found atmospheric hydrogen had increased 70 percent over the course of the 20th century.

    Even as recent air pollution laws have sought to curb fossil fuel emissions, hydrogen emissions have continued to surge with no signs of slowing down. And there's a chance that leakage is to blame.

    No one has directly measured how much hydrogen leaks from these processes, but initial estimates suggest it could be significant.

    They can't be sure this is where the hydrogen is coming from – hydrogen emissions from coal combustion are also seriously understudied – but the authors argue it's worth investigating more.

    Especially since green hydrogen processes, which split hydrogen from water to create carbon-free power, could also result in substantial leakage if they are one day scaled up, as some climate scientists and environmentalists hope they will be.

    If hydrogen one day leaks from industrialized hydrogen gas plants, experts are troubled it could increase the lifetime of methane in our atmosphere, a greenhouse gas 20 times more potent than carbon dioxide.

    to by mě zajímalo proč já mám míň než půlku průměru (4 osoby, teplá plus studená 224l/den, je to teda bytový vodoměr, takže to není super přesné, ale i kdyby to bylo 250l/den tak je to jen cca půlka průměru (62,5l/osoba/den))

    něco se asi spotřebuje v průmyslu? Ani nechodím do práce poslední rok, že bych splachoval tam. Jsem zvědavej na barák, kde chci dešťovkou splachovat

    Almost 90% of the $540bn in global subsidies given to farmers every year are “harmful”, a startling UN report has found.

    This agricultural support damages people’s health, fuels the climate crisis, destroys nature and drives inequality by excluding smallholder farmers, many of whom are women, according to the UN agencies.

    The biggest sources of greenhouse gas emissions, such as beef and milk, received the biggest subsidies, the report said. These are often produced by large industrialised groups that are best placed to gain access to subsidies.

    Without reform, the level of subsidies was on track to soar to $1.8tn (£1.3tn) a year by 2030, further harming human wellbeing and worsening the planetary crisis, the UN said.

    It is interesting to see the many comments on the Agriculture posts. It is equally important to look in the toolbox and see what else might work.

    Agriculture is one area that might hold some hope in helping us store carbon.

    Regenerative Agriculture has alot of different definitions this article goes through the basics.

    In a nutshell it is farming principles and practices that seeks to rehabilitate and enhance the entire ecosystem of the farm by placing a heavy premium on soil health with attention also paid to water management, fertilizer use, and more. It is a method of farming that improves the resources used, rather than destroying or depleting them.

    What should we do to help our farmers ? Would this help them and in turn help us? How can we support them through this transition? We love to hear your comments and suggestions.

    A Soil-Science Revolution Upends Plans to Fight Climate Change
    https://www.quantamagazine.org/a-soil-science-revolution-upends-plans-to-fight-climate-change-20210727/

    “I have The Nature and Properties of Soils in front of me — the standard textbook,” said Gregg Sanford, a soil researcher at the University of Wisconsin, Madison. “The theory of soil organic carbon accumulation that’s in that textbook has been proven mostly false … and we’re still teaching it.”

    The consequences go far beyond carbon sequestration strategies. Major climate models such as those produced by the Intergovernmental Panel on Climate Change are based on this outdated understanding of soil. Several recent studies indicate that those models are underestimating the total amount of carbon that will be released from soil in a warming climate. In addition, computer models that predict the greenhouse gas impacts of farming practices — predictions that are being used in carbon markets — are probably overly optimistic about soil’s ability to trap and hold on to carbon.

    It may still be possible to store carbon underground long term. Indeed, radioactive dating measurements suggest that some amount of carbon can stay in the soil for centuries. But until soil scientists build a new paradigm to replace the old — a process now underway — no one will fully understand why

    ...

    Lehmann, whose studies using advanced microscopy and spectroscopy were among the first to reveal the absence of humus, has become the concept’s debunker-in-chief. A 2015 Nature paper he co-authored states that “the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils.” In 2019, he gave a talk with a slide containing a mock death announcement for “our friend, the concept of Humus.”

    Over the past decade or so, most soil scientists have come to accept this view. Yes, soil is enormously varied. And it contains a lot of carbon. But there’s no carbon in soil that can’t, in principle, be broken down by microorganisms and released into the atmosphere. The latest edition of The Nature and Properties of Soils, published in 2016, cites Lehmann’s 2015 paper and acknowledges that “our understanding of the nature and genesis of soil humus has advanced greatly since the turn of the century, requiring that some long-accepted concepts be revised or abandoned.

    ...

    More recent generations of models, including ones that the Intergovernmental Panel on Climate Change uses for its widely read reports, are essentially palimpsests built on earlier ones, said Torn. They still assume soil carbon exists in long-term and short-term pools. As a consequence, these models may be overestimating how much carbon will stick around in soils and underestimating how much carbon dioxide they will emit.

    Last summer, a study published in Nature examined how much carbon dioxide was released when researchers artificially warmed the soil in a Panamanian rainforest to mimic the long-term effects of climate change. They found that the warmed soil released 55% more carbon than nearby unwarmed areas — a much larger release than predicted by most climate models. The researchers think that microbes in the soil grow more active at the warmer temperatures, leading to the increase

    ...

    Another related, and poorly understood, ingredient in a new soil paradigm is the fate of carbon within the soil. Researchers now believe that almost all organic material that enters soil will get digested by microbes. “Now it’s really clear that soil organic matter is just this loose assemblage of plant matter in varying degrees of degradation,” said Sanderman. Some will then be respired into the atmosphere as carbon dioxide. What remains could be eaten by another microbe — and a third, and so on. Or it could bind to a bit of clay or get trapped inside a soil aggregate: a porous clump of particles that, from a microbe’s point of view, could be as large as a city and as impenetrable as a fortress. Studies of carbon isotopes have shown that a lot of carbon can stick around in soil for centuries or even longer. If humus isn’t doing the stabilizing, perhaps minerals and aggregates are

    ...

    Researchers agree that soil science is in the midst of a classic paradigm shift. What nobody knows is exactly where the field will land — what will be written in the next edition of the textbook. “We’re going through a conceptual revolution,” said Mark Bradford, a soil scientist at Yale University. “We haven’t really got a new cathedral yet. We have a whole bunch of churches that have popped up.

    Walter Jehne -- Understanding the Water Cycle: And the potential for rapid global cooling
    https://youtube.com/watch?v=_TsX7ffouxQ&feature=youtu.be


    We understand that the health and regeneration of soil ecosystems, and by extension the plant and animal communities with which they are interdependent, are critical to the sequestration of carbon and foundational to any successful efforts to mitigate the impacts of climate change. But there is a vital part of the story of soil regeneration and global climate mitigation that hasn’t been as well covered as the carbon cycle – and that is the global water cycle.

    Walter will explore how soil biology controls the water cycle, and how the water cycle regulates the planet’s heating and cooling processes. He will provide a deep look at the intersection of soil regeneration practices and the restoration of hydrological processes. Participants will gain insight and inspiration toward practices they can apply to their own farms and gardens, as well as a larger context of theory that integrates our knowledge of the water cycle and its role in regulating global temperature with current efforts toward conservation and regeneration of living soils.
