    Bamboo Revolution: Social Tipping Point for Planetary Climate Migration?

    Paul Maidowski studied International Relations in Dresden, Beijing, and Boston and worked in international climate negotiations and renewable energies. He currently explores the climate mitigation potential of bamboo for future worlds with elevated atmospheric CO2 concentrations.

    We're nearly halfway through the 2020s, dubbed the most decisive decade for action on climate change. Where exactly do things stand? Climate impact scholar Johan Rockström offers the most up-to-date scientific assessment of the state of the planet and explains what must be done to preserve Earth's resilience to human pressure.

    planetary overpopulation?


    Is Humanity REALLY Heading for Population Collapse?! Aaron Bastani meets Paul Morland
    https://youtu.be/9TusC0_h100?si=Xf5Wl52Kv_Qa3wrW



    During 1960s, fears of planetary ‘overpopulation’ became widespread. And yet, in more recent years, an altogether different worry has emerged: future population decline. Fertility rates have fallen for decades - and in some places centuries - as humans live in cities, gender equality improves and access to birth control becomes widespread. But, according to some, if they fall too far, and too fast, the basis of the modern welfare state is in jeopardy - not to mention our entire economic order. Could falling birth rates, combined with increased life expectancy, even if not universal, really be as big a challenge in the 21st century as climate breakdown and runaway inequality? Or is this just another moral panic with no basis in fact?

    To discuss all of that Aaron Bastani is joined by Dr Paul Morland, a demographer whose latest book is titled “No One Left”. Dr Morland’s previous books include “The Human Tide” and “Tomorrow’s People: The Future of Humanity in Ten Numbers

    hypercarnivory


    As “Hypercarnivores", Humans Were Apex Predators For 2 Million Years | IFLScience
    https://www.iflscience.com/as-hypercarnivores-humans-were-apex-predators-for-2-million-years-59296

    new research suggests that our ancestors obtained the majority of their nutrition from meat, and only diversified their food intake to include more plants at the very end of the Stone Age. Published in the American Journal of Physical Anthropology, the new study indicates that humans were apex predators for around 2 million years, with numerous species within the Homo lineage engaging in “hypercarnivory”.

    ...

    Determining the trophic level – or position within the food web – of ancient humans is tricky, as we can’t directly observe the feeding behaviors of our early ancestors. Most attempts to do so have therefore focused on present-day hunter-gatherer groups, assuming that the practices of such cultures reflect those of primitive humans.

    However, the authors of this latest study explain that such comparisons are highly problematic, as changes to the ecological landscape will inevitably have forced humans to alter their hunting and gathering preferences over time. For instance, the loss of megafauna like mammoths and other large animals produced a major shift in human diets.

    The researchers therefore attempted to reconstruct the diet of ancient humans and determine the trophic level of our ancestors throughout the Pleistocene, which began 2.5 million years ago and ended around the time of the agricultural revolution, some 11,000 years ago. Taking a multidisciplinary approach, the team examined over 400 scientific studies covering areas such as genetics, metabolism, morphology, archaeology, and paleontology in order to determine whether early humans were specialized carnivores or more general omnivores.



    2021 The evolution of the human trophic level during the Pleistocene
    https://onlinelibrary.wiley.com/doi/10.1002/ajpa.24247

    The evidence shows that the trophic level of the Homo lineage that most probably led to modern humans evolved from a low base to a high, carnivorous position during the Pleistocene, beginning with Homo habilis and peaking in Homo erectus. A reversal of that trend appears in the Upper Paleolithic, strengthening in the Mesolithic/Epipaleolithic and Neolithic, and culminating with the advent of agriculture. We conclude that it is possible to reach a credible reconstruction of the HTL without relying on a simple analogy with recent hunter-gatherers' diets. The memory of an adaptation to a trophic level that is embedded in modern humans' biology in the form of genetics, metabolism, and morphology is a fruitful line of investigation of past HTLs, whose potential we have only started to explore.

    Climate Leviathan: A Political Theory of Our Planetary Future | Verso Books
    https://www.versobooks.com/products/520-climate-leviathan

    To further the struggle for climate justice, we need to have some idea how the existing global order is likely to adjust to a rapidly changing environment. Climate Leviathan provides a radical way of thinking about the intensifying challenges to the global order. Drawing on a wide range of political thought, Joel Wainwright and Geoff Mann argue that rapid climate change will transform the world's political economy and the fundamental political arrangements most people take for granted. The result will be a capitalist planetary sovereignty, a terrifying eventuality that makes the construction of viable, radical alternatives truly imperative.

    2024 The cryptoterrestrial hypothesis: A case for scientific openness to a concealed earthly explanation for Unidentified Anomalous Phenomena
    https://www.researchgate.net/publication/381041896_The_cryptoterrestrial_hypothesis_A_case_for_scientific_openness_to_a_concealed_earthly_explanation_for_Unidentified_Anomalous_Phenomena

    Recent years have seen increasing public attention and indeed concern regarding Unidentified Anomalous Phenomena (UAP). Hypotheses for such phenomena tend to fall into two classes: a conventional terrestrial explanation (e.g., human-made technology), or an extraterrestrial explanation (i.e., advanced civilizations from elsewhere in the cosmos). However, there is also a third minority class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of the universe. This is the ultraterrestrial hypothesis, which includes as a subset the "cryptoterrestrial" hypothesis, namely the notion that UAP may reflect activities of intelligent beings concealed in stealth here on Earth (e.g., underground), and/or its near environs (e.g., the moon), and/or even "walking among us" (e.g., passing as humans). Although this idea is likely to be regarded sceptically by most scientists, such are the nature of some UAP that we argue this possibility should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness.
