    Walter Jehne's presentation on "The soil-microbe-root interface in the evolution, resilience and future of life on land". International Nature Farming Convergence, Dec 2-4, 2021.

    Walter Jehne:The soil-microbe-root interface in the evolution, resilience and future of life on land
    https://youtu.be/XYJq6c2pg5s


    Walter presents a landmark historical synopsis of geology, biology, and soil carbon functions over 4.5 billion years; why "agroecosystems that mimic nature" matter aka natural farming; the critical importance of soil carbon and why the health of planet earth depends on addressing the soil carbon sponge and hydrogeological cycles.

    ...

    Walter Jehne, retired soil scientist with CSIRO in Australia, gave a mind-blowing synopsis on the evolution of geochemistry and soil biology at the International Nature Farming Virtual Convergence on Saturday. It essentially demonstrated how industrial agriculture has burned off soil carbon with destructive farming practices, and secondly how natural farming practices can regenerate soil health, create a soil carbon sponge, reinvigorate hydrogeological cycles, and stave off dire planetary climate change.

    Themes: designing agroecosystems that mimic nature, soil organic matter management, soil carbon sponge, water cycles. Natural and regenerative farmers are proving beyond a shadow of a doubt these practices are solid, economical and ecological on a worldwide basis.

    Waler Jehne nails why alternative farming movements -- with their constant attention to SOIL BIOLOGY HABITAT and SOIL CARBON FARMING -- have fought tooth and nail for 50-100 years to make a difference: compost, cover crops, mulches, keep the soil covered, minimize soil distrurbance, biodiversity, integrated crop-livestock farming systems, keep your worms and soil biology happy!

    Early humans hunted the largest available animals to extinction for 1.5 million years
    https://phys.org/news/2021-12-early-humans-largest-animals-extinction.html

    A groundbreaking study by researchers from Tel Aviv University tracks the development of early humans' hunting practices over the last 1.5 million years—as reflected in the animals they hunted and consumed. The researchers claim that at any given time early humans preferred to hunt the largest animals available in their surroundings, which provided the greatest quantities of food in return for a unit of effort.

    In this way, according to the researchers, early humans repeatedly overhunted large animals to extinction (or until they became so rare that they disappeared from the archaeological record) and then went on to the next in size—improving their hunting technologies to meet the new challenge. The researchers also claim that about 10,000 years ago, when animals larger than deer became extinct, humans began to domesticate plants and animals to supply their needs, and this may be why the agricultural revolution began in the Levant at precisely that time.

    The study was conducted by Prof. Ran Barkai and Dr. Miki Ben-Dor of the Jacob M. Alkow Department of Archaeology and Ancient Near Eastern Cultures, Prof. Shai Meiri of the School of Zoology and Steinhardt Museum of Natural History, and Jacob Dembitzer, a research student of Prof. Barkai and Prof. Meiri, who led the project. The paper was published in the journal Quaternary Science Reviews.

    The Thwaites Glacier in Antarctica is larger than the Czech Republic, Austria and Switzerland combined, it is already melting and is responsible for 4% of the global rise in sea level.

    However, researchers from the American Geophysical Union have now found huge diagonal cracks across the ice shelf that are growing ever faster. The prognosis: in the next five years the ice mass could collapse suddenly. What would that mean?

    The ice shelf will likely break up into countless icebergs, and the rest of the glacier will then drain into the sea about three times faster. For comparison: in the last 30 years the pace has "only" doubled.

    In the best-case scenario, the contribution to sea level rise increases by 1%. In the long term, his contribution would be 65cm. But worse, the Thwaites Glacier is like a plug. When it melts, the neighboring glaciers slide into its basin and melt too.

    As a result, the entire ice in West Antarctica is gradually disappearing and the sea level is rising by up to 3.3 meters. And the ice cannot come back, because the oceans are much warmer than when the great glaciers were formed. Gone is gone.

    Let's put that in a context: This is exactly what the IPCC warned about this year with "ice sheet instability". Our maps would have to be redrawn



    Most likely, there is nothing we can do about the collapse. Millions of people are practically dead, just not yet dropped. NOW should our preparations begin to organize asylum for the displaced in the industrialized countries. It will be historically unique.
    This message really comes at the wrong time. Only a few weeks ago, strong statistical evidence was found in Greenland that the egg melt is now irreversible. Shortly before that, a study predicted a sea level rise of 5cm PER YEAR from 2060 onwards.

    Every five years the sea level would rise as much as it has from the beginning of industrialization until today. The power of exponential growth, experienced first hand ...

    I have simplified a few things: There are other processes at work, the glacier melts, for example, through a kind of tide pump "from below". It is essential that we are entering a phase in which the climate crisis is being driven by factors over which we can no longer influence.

    Nemonte Nenquimo: The forest is our teacher. It's time to respect it | TED Talk
    https://www.ted.com/talks/nemonte_nenquimo_the_forest_is_our_teacher_it_s_time_to_respect_it/

    For thousands of years, the Amazon rainforest has provided food, water and spiritual connection for its Indigenous inhabitants and the world. But the endless extraction of its natural resources by oil companies and others is destroying the lives of those who live there, says Waorani leader Nemonte Nenquimo, and threatening the overall stability of Earth's biosphere. In this powerful talk, she reminds us of the destruction that continues to happen to the world's largest tropical rainforest -- and demands respect for Mother Nature. "The forest is our teacher," she says. (Filmed in Ecuador by director Tom Laffay and associate producer Emily Wright, in collaboration with Amazon Frontlines. In Spanish with subtitles.)

    Brazil’s Amazon hit by worst deforestation since 2006
    https://www.washingtonpost.com/world/2021/11/19/amazon-deforestation-brazil-15years/?s=09

    The Amazon in Brazil lost more than 5,000 square miles of rainforest from August 2020 to July 2021, the government research center said in a report that was dated Oct. 27 and shared on Thursday. It was the fourth year in a row that the rate of deforestation rose, it said.

    Climate activists have warned of the risks of letting the global pledge fall short: The devastation of forests drives up greenhouse gas emissions, and Global Forest Watch found the world lost 411 million hectares of forest between 2001 and 2020 — roughly half the size of the United States.

    Greta Thunberg on the State of the Climate Movement and the roots of her power as an activist

    https://www.washingtonpost.com/magazine/2021/12/27/greta-thunberg-state-climate-movement-roots-her-power-an-activist/

    “Right now, what’s holding us back is that we lack that political will. We don’t prioritize the climate today. Our goal is not to lower emissions. Our goal is to find solutions that allow us to continue life [as it is] today. And, of course, you can ask, “Can’t we have both?” But the uncomfortable truth is that we have left it too late for that. Or the world leaders have left it too late for that. We need to fundamentally change our societies now. If we would have started 30 years ago, it would have been much smoother. But now it’s a different situation.”

    A Ač
    https://m.facebook.com/story.php?story_fbid=10159391013691999&id=566311998

    Post-covidová obnova ekonomiky mala byť "zelená". Teda taká, ktorá sa menej spolieha na fosílne palivá, a (ideálne) naštartuje rýchlejší pokles globálnej spotreby fosílnych palív. Nič také sa však nestalo.

    V roku 2021 narástla globálna emisia CO2 najviac v histórii hneď po roku 2010. Celková spotreba fosílnych palív sa tak priblížila k pred-pandemickému rekordu z roku 2019.

    Šancu održať oteplenie "výrazne pod 2° C" sme už premrhali, udržať oteplenie pod 2 °C je extrémne nepravdepodobné.

    Samozrejme, vždy sa môžeme spoliehať na to, že "budúci rok to bude lepšie".
