    The faulty science, doomism, and flawed conclusions of Deep Adaptation | openDemocracy
    https://www.opendemocracy.net/...nomy/faulty-science-doomism-and-flawed-conclusions-deep-adaptation/

    To be totally clear, we argue that all of the following are simultaneously true:

    1. There is an unprecedented global climate and ecological emergency. If governments do not undertake enormous measures to mitigate climate change, then some form of “societal collapse” is plausible — albeit in varying forms and undoubtedly far worse for the poorest people.

    2. Policymakers and society at large are not treating this grave threat with anything approaching sufficient urgency.

    3. The climate crisis is dire enough in any case to justify urgent action, including mass sustained nonviolent disruption, to pressure governments to address it swiftly.

    4. However, neither social science nor the best available climate science support Deep Adaptation’s core premise: that near-term societal collapse due to climate change is inevitable.

    5. This false belief undermines the environmental movement and could lead to harmful political decisions, overwhelming grief, and fading resolve for decisive action.

    6. Respecting the distinction between the coming hardships and unstoppable collapse clarifies our agency to minimise future harm by mitigating and adapting to climate change, whilst freeing us from moral and political blinkers.




    The Darkest Timeline
    https://www.nytimes.com/2020/12/26/style/climate-change-deep-adaptation.html

    In July, with Colleen Schmidt, who is 24 and has a degree in environmental biology from Columbia — and who acted as their de facto editor — they published a paper.

    “I would call it a hit piece on the paper and by implication, the framework and the movement,” Mr. Bendell said. “It was quite upsetting, and I wasn’t sure how best to respond.”

    About two weeks after Mr. Hall, Mr. Nicholas and Ms. Schmidt published their paper, Mr. Bendell released a second version of his Deep Adaptation paper.

    “This paper appears to have an iconic status amongst some people who criticize others for anticipating societal collapse,” he writes. “Therefore, two years on from initial publication, I am releasing this update.”

    The stark statement that had opened the original paper was altered. Once, it had said its purpose was to provide readers “with an opportunity to reassess their work and life in the face of an inevitable near term social collapse due to climate change.” Now, to emphasize that the idea remains unproven, it reads “in the face of what I believe to be an inevitable near-term societal collapse.” Mr. Bendell added a sentence stating plainly that the paper does not prove that inevitability.

    As the summer of 2020 ended, he announced on his blog that he would be stepping back from the Deep Adaptation forum, a decision he said he’d been planning for a year.

    In this quiet, he is working on a new paper. In it, he said, he plans to explain exactly how the coming catastrophe of our society will play itself out, describing the starvation and mass death that so many anticipate.

    The three young people who wrote the paper rebutting Deep Adaptation agree that the climate crisis has already resulted in horrific loss and that it will continue to exact a heavy toll. But they also believe that governments around the world can still make a difference and should be held to account, instead of being lulled into inaction by despair.

    “We’ve lost some things,” Ms. Schmidt said. “We could lose everything. But there is no reason not to try and make what can work, work.”

    2020 Can Green Hydrogen Production Be Economically Viable under Current Market Conditions
    https://www.mdpi.com/1996-1073/13/24/6599/pdf

    This paper discusses the potential of green hydrogen production in a case study of a Slovenian hydro power plant. To assess the feasibility and eligibility of hydrogen production at the power plant, we present an overview of current hydrogen prices and the costs of the power-to-gas system for green hydrogen production. After defining the production cost for hydrogen at the case study hydro power plant, we elaborate on the profitability of hydrogen production over electricity. As hydrogen can be used as a sustainable energy vector in industry, heating, mobility, and the electro energetic sectors, we discuss the current competitiveness of hydrogen in the heating and transport sectors. Considering the current prices of different fuels, it is shown that hydrogen can be competitive in the transport sector if it is unencumbered by various environmental taxes. The second part of the paper deals with hydrogen production in the context of secondary control ancillary service provided by a case study power plant. Namely, hydrogen can be produced during the time period when there is no demand for extra electric power within a secondary control ancillary service, and thus the economics of power plant operation can be improved.

    2016 Megafauna and ecosystem function from the Pleistocene to the Anthropocene
    https://www.pnas.org/content/pnas/113/4/838.full.pdf

    the wider environmental impacts of megafaunal abundance and loss are only just making their way into mainstream environmental thinking. In regions of recent or ongoing megafaunal decline, there are often concurrent changes in ecosystem structure, energy and nutrient flow, composition, and genetic structure that cascade from changes in megafaunal abundance. In looking at even wild landscapes where megafauna are long gone, imagining such landscapes as recently teeming with elephants, sabertooths, and other giant herbivores and carnivores can yield fresh perspectives on contemporary ecosystem questions, ranging from the distribution of tropical savannas and grasslands, through the natural ranges and abundance of extant animals, to the response of high latitude systems to climate change. Whether megafaunal rewilding is appropriate, acceptable, practical, or not, such a perspective challenges our thinking about what kind of nature we seek to conserve or create (33, 97, 98).

    In recent decades, Earth systems science has emerged as an important new discipline focused on understanding the interactions of the biosphere, atmosphere, and oceans in the context of global change. To date, in this new discipline, nonhuman or nondomestic animals are still largely invisible, assumed to be passive inhabitants and consumers of a world where plants dominate biogeochemical processes, with vegetation distribution and cover determined by abiotic factors (climate, soils, atmospheric CO2) and human decisions on ecosystem use. This viewpoint is a legacy of a world where animal control of ecosystem function has been diminished by massive extinction. Recognition of the view that much terrestrial surface cover is potentially strongly influenced by megafaunal top-down controls allows a more complete understanding of the interactions among humans, megafauna, fire, soils, and climate in determining the geography and structure of the biosphere. There is new appreciation of the significant role of megafauna in regional and global biogeochemical cycling, accompanied by the first attempts to mathematically model these processes, both on land (20, 51) and in the oceans (48, 86). New modeling approaches (105) explicitly allow for a trophic framework for quantitative representation of megafaunal effects in Earth system models. These approaches are still in their infancy, but, if we are to understand ecosystem functioning in the megafaunal past, or how megafaunal changes are one of the agents of contemporary global ecosystem change, or the possible role for megafaunal restoration in future ecosystems, such models can provide an essential quantitative framework that needs to be further developed and tested.

    More philosophically, the Pleistocene and early Holocene megafaunal extinctions can stimulate us to reevaluate what is natural in the world and what sort of natures we seek to conserve or restore. If we accept the increasing evidence for a strong human role in these early extinctions, it forces a look inwards and recognition of the deep prehistoric entanglement between humans and environmental change, a realization that some of the most dramatic human-induced changes to the nature of life on Earth and the functioning of the biosphere may have occurred even before the dawn of agriculture.

    I wanted to share with you the news about my new book, 'The case for Degrowth' is out

    2020 The Case for Degrowth
    https://politybooks.com/bookdetail/?isbn=9781509535620

    This is the best thing we've written on degrowth to date, a pocket mini-festo of 20,000 words (at an equivalent price of 11 Euros), but dense with new ideas on how to articulate the personal, the communal and the political in a degrowth direction.


    In other news, I am happy to share with you in the link below some of my other publications this year: https://www.dropbox.com/sh/y5qjdk63qo6p46h/AADE1e9ZnWME0cl-E9ZwQLzIa?dl=0

    - a paper with Giacomo D'Alisa on degrowth and the state, where we pre-figured the politics of 'the case for' book.
    - a paper with Tilman Hartley and Jeroen van den Bergh where we examine what type of policies could increase equality if there is no growth.
    - our 'hit' paper with Jason Hickel TADEAS on green growth and whether it is possible (spoiler - it is not).
    - and a paper with a team of authors led by Iago Otero calling for biodiversity policies without growth.

    I've also put some order into my Youtube channel, which you can check out and find some short presentations and discussions of 'the case for', as well as some older presentations of my previous book, Limits. https://www.youtube.com/user/giorgoskallis

    2015 Exploring the influence of ancient and historic megaherbivore extirpations on the global methane budget
    https://www.pnas.org/content/113/4/874.short

    Here, we quantify one potential effect of the decline of large herbivores: the reduction of the greenhouse gas methane released as a byproduct of plant digestion. We examine three time periods where large-scale losses of megaherbivores occurred—the African rinderpest epizootic of the 1890s, the massive Great Plains bison kill-off in the 1860s, and the terminal Pleistocene extinction of megafauna. We find detectable decreases in the global methane budget related to the extirpation of megaherbivores. Our findings underscore the importance of large mammals in regulating ecosystems and feedbacks on climate.

    ...

    Using global datasets of late Quaternary mammals, domestic livestock, and human population from the United Nations as well as literature sources, we develop a series of allometric regressions relating mammal body mass to population density and CH4 production, which allows estimation of methane production by wild and domestic herbivores for each historic or ancient time period. We find the extirpation of megaherbivores reduced global enteric emissions between 2.2–69.6 Tg CH4 y−1 during the various time periods, representing a decrease of 0.8–34.8% of the overall inputs to tropospheric input. Our analyses suggest that large-bodied mammals have a greater influence on methane emissions than previously appreciated and, further, that changes in the source pool from herbivores can influence global biogeochemical cycles and, potentially, climate.

    2017 Integrating Herbivore Population Dynamics Into a Global Land Biosphere Model: Plugging Animals Into the Earth System
    https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016MS000904

    In this study, we coupled herbivore population dynamics in a global land model (the Dynamic Land Ecosystem Model, DLEM 3.0) to simulate populations of horses, cattle, sheep, and goats, and their responses to changes in multiple environmental factors at the site level across different continents during 1980–2010. Simulated results show that the model is capable of reproducing observed herbivore population dynamics across all sites for these animal groups. Our simulation results also indicate that during this period, climate extremes led to a maximum mortality of 27% of the total herbivores in Mongolia. Across all sites, herbivores reduced aboveground net primary productivity (ANPP) and heterotrophic respiration (Rh) by 14% and 15%, respectively (p lower than 0.05). With adequate parameterization, the model can be used for historical assessment and future prediction of mammalian herbivore populations and their relevant impacts on biogeochemical cycles. Our simulation results demonstrate a strong coupling between primary producers and consumers, indicating that inclusion of herbivores into the global land modeling framework is essential to better understand the potentially large effect of herbivores on carbon cycles in grassland and savanna ecosystems.

    2020: The Year Things Started Going Badly Wrong | Our Finite World
    https://ourfiniteworld.com/2020/12/23/2020-the-year-things-started-going-badly-wrong/

    komentar:

    I've been calling Gail's work the "Critique of Thermodynamic Economy." It is distinct from the Marx-Engels "Critique of Political Economy" set out in the volumes of Das Kapital. In the days when that early work was written, the question of the energy return on investment was not even called into question. It was all about the capital-labour equation.

    It was imagined, in the 1860s-1890s, that high-quality energy was infinite in supply, so it was not the matter of concern; rather, the fate of labour was the concern.

    Now, in the 21st, we've entered a whole other new era when I think the Critique of Thermodynamic Economy is the crucial thing to get correct about. Gail is steering us in that direction, I think.

    Is The Green Hydrogen Hype Justified? | OilPrice.com
    https://oilprice.com/...native-Energy/Renewable-Energy/Is-The-Green-Hydrogen-Hype-Justified.amp.html

    Path to Hydrogen Competitiveness: A Cost Perspective - Hydrogen Council
    https://hydrogencouncil.com/en/path-to-hydrogen-competitiveness-a-cost-perspective/


    The Green Hydrogen Catapult initiative will try to scale green hydrogen 50-fold in the next six years. The initiative will leverage the support of the Rocky Mountain Institute, a U.S.-based nonprofit organization.

    The race to zero emissions is aiming for the deployment of 25 gigawatts through 2026 of renewables-based hydrogen production.

    ...

    “Having led the race to deliver photovoltaic energy at well-below US$2 cents per kilowatt-hour, in certain geographies, we believe the collective ingenuity and entrepreneurship of the private sector can deliver green hydrogen at less than US$2 per kilogram within four years,” said Paddy Padmanathan, chief executive of ACWA Power, in a release. “From an industry perspective, we see no technical barriers to achieving this, so it’s time to get on with the virtuous cycle of cost reduction through scale up.

    ...

    The paper by The Hydrogen Council concluded that hydrogen is “already scaling up” and considerable investments are being made globally. Furthermore, green hydrogen will provide an important low-carbon option across a wide range of sectors.

    However, hydrogen’s development still requires suitable financial, infrastructural and policy support to achieve wide deployment and scale-up through commercial projects.

    ...

    According to a report by Greentech Media, ACWA Power is already working with U.S. firm Air Products & Chemicals on a U.S. $5 billion green hydrogen plant in Saudi Arabia. Four gigawatts of wind and solar will power the plant, which will produce 650 tons of the gas per day.

    Meanwhile, according to the findings in a paper titled “Path To Hydrogen Competitiveness A Cost Perspective” by The Hydrogen Council, scale-up will be the biggest driver of cost reduction, notably in the production and distribution of hydrogen.

    This will deliver significant cost reductions, even before any additional impact from technological breakthroughs.

    Agriculture must change, with different skills and a new attitude required | MinnPost
    https://www.minnpost.com/...riculture-must-change-with-different-skills-and-a-new-attitude-required/

    For Earth to remain viable for human habitation for more than a few decades, agriculture must change.

    It must give up its centuries-old fascination with annual crops like wheat and corn, and begin the study of how perennial plants fit food production. Perennial plants, properly managed as under a good planned grazing regimen, incorporate atmospheric carbon into the soil as organic matter, thus beginning to reverse centuries of burning off carbon through tillage. Even carefully planned rotations of annual plants without tillage will not safeguard soil and build organic matter like a good stand of perennials.

    Perennial plants must be developed for food production instead of this shortsighted focus on breeding plants that can withstand chemical applications. Wes and Dana Jackson established the Land Institute, a nonprofit research center in Salina, Kansas, in 1976, and have been working on perennial replacements for annual crops ever since. They and their staff developed Kernza from intermediate wheatgrass, useful for both grazing and its wheat-like kernel. It is currently being distributed and commercialized by the University of Minnesota with the help of certain grain milling and baking businesses. Another ongoing study is of Illinois Bundleflower, a potential protein source for livestock and humans.

    Production of perennial crops requires close on-site management driven by observation, experience and a feel for natural systems. This is especially evident for Kernza production, which is best done by a mix of cropping and livestock systems. We have few people in the farm population even capable of this breadth of management anymore. A different set of farming skills and a new attitude are required. It will take both time and financial stability to learn them, and then to apply them. The need for decision-making based upon observation and knowledge of place and its biology presupposes that operations cannot be huge. Perennial agriculture will create a different human social structure around it.

    Rozumné řešení uhlíkové stopy je zase o kousek blíž. V úterý jsme s Výborem pro průmysl, výzkum a energetiku (ITRE) měli mimořádné setkání, kde jsme hlasovali o tzv. uhlíkovém clu. To by měla Evropská komise představit v roce 2021 a zavést v roce 2023. Uhlíkové clo je vlastně daní, která by platila na zboží vyrobené mimo Evropskou unii podle objemu jeho uhlíkové stopy. Má to smysl, protože pokud bude Evropa díky Green Dealu snižovat uhlíkovou stopu dřív než jiné země, nebudou evropské firmy s vyššími standardy znevýhodněny oproti těm, které životní prostředí ignorují.
    Clo řeší problém, kdy řada společností vypouští vysoký objem emisí, aniž by za ně nesla odpovědnost. Znečišťovatel tak bude mít zodpovědnost za emise, které vytvoří. ☑️
