2020 Planetary Social Thought: The Anthropocene Challenge to the Social Sciences
https://www.academia.edu/...anetary_Social_Thought_The_Anthropocene_Challenge_to_the_Social_Sciences

This is an unpublished full draft of a book by Nigel Clark and Bronislaw Szerszynski, due to be published by Polity Press in late 2020.

More than just putting new causes for alarm on the agenda, we argue in this book, the Anthropocene offers incitements for thinking about our planet across a range of timescales, fields of vision and trajectories. Such provocations, we propose, can and ought to prompt us to ask some far-reaching questions. What kind of planet is this on which we find ourselves? What has our planet done in the past and what might it be capable of doing in the future? And closely associated with these ‘planetary’ themes, we also need to ask: what kind of creature or being are we? How have ‘we’ inhabited and made use of this planet in the past, and what might we find ourselves doing with the Earth and all its shifting, changeable processes in the future? This is what we refer to as planetary social thought.

2018 The Anthropocene Generalized: Evolution of Exo-Civilizations and Their Planetary Feedback
https://www.liebertpub.com/doi/full/10.1089/ast.2017.1671

We present a framework for studying generic behaviors possible in the interaction between a resource-harvesting technological civilization (an exo-civilization) and the planetary environment in which it evolves. Using methods from dynamical systems theory, we introduce and analyze a suite of simple equations modeling a population which consumes resources for the purpose of running a technological civilization and the feedback those resources drive on the state of the host planet. The feedbacks can drive the planet away from the initial state the civilization originated in and into domains that are detrimental to its sustainability. Our models conceptualize the problem primarily in terms of feedbacks from the resource use onto the coupled planetary systems. In addition, we also model the population growth advantages gained via the harvesting of these resources. We present three models of increasing complexity: (1) Civilization-planetary interaction with a single resource; (2) Civilization-planetary interaction with two resources each of which has a different level of planetary system feedback; (3) Civilization-planetary interaction with two resources and nonlinear planetary feedback (i.e., runaways). All three models show distinct classes of exo-civilization trajectories. We find smooth entries into long-term, “sustainable” steady states. We also find population booms followed by various levels of “die-off.” Finally, we also observe rapid “collapse” trajectories for which the population approaches n = 0. Our results are part of a program for developing an “Astrobiology of the Anthropocene” in which questions of sustainability, centered on the coupled Earth-system, can be seen in their proper astronomical/planetary context. We conclude by discussing the implications of our results for both the coupled Earth system and for the consideration of exo-civilizations across cosmic history

We develop a classification scheme for the evolutionary state of planets based on the non-equilibrium thermodynamics of their coupled systems, including the presence of a biosphere and the possibility of what we call an “agency-dominated biosphere” (i.e. an energy-intensive technological species). The premise is that Earth’s entry into the “Anthropocene” represents what might be, from an astrobiological perspective, a predictable planetary transition. We explore this problem from the perspective of the solar system and exoplanet studies. Our classification discriminates planets by the forms of free energy generation driven from stellar forcing. We then explore how timescales for global evolutionary processes on Earth might be synchronized with ecological transformations driven by increases in energy harvesting and its consequences (which might have reached a turning point with global urbanization). Finally, we describe quantitatively the classification scheme based on the maintenance of chemical disequilibrium in the past and current Earth systems and on other worlds in the solar system. In this perspective, the beginning of the Anthropocene can be seen as the onset of the hybridization of the planet – a transitional stage from one class of planetary systems interaction to another. For Earth, this stage occurs as the effects of human civilization yield not just new evolutionary pressures, but new selected directions for novel planetary ecosystem functions and their capacity to generate disequilibrium and enhance planetary dissipation.

China’s current goal is to derive as much as 20% of its primary energy use from non-fossil fuels by 2030. One option under consideration is to bring forward that target, according to people familiar with the discussions who asked not to be identified, possibly to 2025. Another proposal is to cut the share of coal in the energy mix to 52% by 2025, from the 57.5% planned for the end of this year, one of the people said.

...

Still, China has done a little better than it expected in its transition to clean energy so far, even as it remains the world’s biggest miner and consumer of coal. The share of non-fossil fuels in the energy mix was 15.3% in 2019, surpassing the 15% goal set for 2020.

Chinese renewable energy stocks have been on a tear on speculation that Beijing could increase its requirements for solar and wind power. Bringing forward the 20% target to 2025 could see solar installations more than triple from 2019 levels to 105 gigawatts a year, while wind could almost double to 48 gigawatts, Zhu Yue, an analyst at Industrial Securities Co., said in a note.

The Climate Alarms Are Blaring — Are People Not Hearing Them? 
https://cleantechnica.com/2020/09/17/the-climate-alarms-are-blaring-are-people-not-hearing-them/

As the fires on the US West Coast grow more intense, and as thousands flee their homes, one has to wonder — are we unable to perceive the climate’s warning signs or are we, as a species, truly this parasitic? 

Potenciál vybraných způsobů snížení emisí v ČR

Nejvyšší emisní úspory by bylo dosaženo v případě realizace scénáře, vypracovaného v červenci 2020 společností Bloomberg NEF. Scénář je součástí studie, která se primárně zabývá možností dekarbonizace energetického sektoru ve státech EU, které mají vysoký podíl fosilních zdrojů a přitom stále nemají stanovený termín odstavení uhelných elektráren. Ve výsledku tak modeluje přechod na nízkouhlíkovou energetiku pro Polsko, Česko, Rumunsko a Bulharsko. Dle zmíněného scénáře je do roku 2030 možné dosáhnout úspory 24 milionů tun CO2eq. V rámci tohoto scénáře se počítá hlavně s rozvojem větrných elektráren. Těch by mělo přibýt celkem 4,1 GW instalovaného výkonu, což odpovídá necelým 1400 větrným elektrárnám o jednotkovém výkonu 3 MW). Rozvoj fotovoltaiky zůstává přibližně na úrovni Návrhu vnitrostátního plánu (viz výše). Další detaily jsou uvedeny ve studii (kapitola 4.2). Celkové náklady na realizaci tohoto scénáře byly vyjádřeny na přibližně 5,8 miliard EUR (lehce přes 150 miliard Kč, což odpovídá cca 10 % výdajů státního rozpočtu v roce 2019 nebo zhruba oficiálně udávaným nákladům na nový blok v Dukovanech).
