Pedia Sapiens: A New Genesis Future

Future > Old World

Turner, Monica, et al. Climate Change, Ecosystems and Abrupt Change. Philosophical Transactions of the Royal Society B.. January, 2020. Thirteen environmentalists from across the USA, the UK, Australia, and Germany including Anke Jentsch and Timothy Lenton emphasize the increasing vicarious occurrence of rapid decadal or even annual system shifts and then offer integral project guidance going forward.

Ecologists have long studied patterns, directions and tempos of change, but there is a current need to understanding empirical observations of abrupt changes as climate warming accelerates. Abrupt changes in ecological systems (ACES) are everywhere increasing in frequency. We highlight insights from diverse ACES studies: ecological systems show ACES in some dimensions but not others; climate extremes are important in generating ACES; contingencies, such as ecological memory, frequency and sequence of disturbances, and spatial context play a role; and tipping points are often associated with ACES. Progress in understanding ACES requires strong integration of scientific approaches (theory, observations, experiments and process-based models) and high-quality empirical data drawn from a diverse array of ecosystems.

Xu, Chi, et al. Future of the Human Climate Niche. Proceedings of the National Academy of Sciences. 117/11350, 2020. International scholars from China, the UK, USA, Denmark and the Netherlands including Tim Lenton and Marten Scheffer point out that while anthropo sapiens has spread all over the Earth, the most inhabiting populations have confined themselves to narrower, defined zones. By this view, these preferred areas come under even more impact, constraint and imminent peril.

We show that for thousands of years, humans have concentrated in a surprisingly narrow subset of Earth’s available climates, characterized by mean annual temperatures around ∼13 °C. This distribution likely reflects a human temperature niche related to fundamental constraints. We demonstrate that depending on scenarios of population growth and warming, over the coming 50 y, 1 to 3 billion people are projected to be left outside the climate conditions that have served humanity well over the past 6,000 y. Absent climate mitigation or migration, a substantial part of humanity will be exposed to mean annual temperatures warmer than nearly anywhere today. (Significance)

Ghil, Michael and Valerio Lucarini. The Physics of Climate Variability and Climate Change. Reviews of Modern Physics. Online March, 2020. Ecole Normale Superieure, Paris and University of Reading, UK geoscientists post an 86 page tutorial as dynamic geologic, oceanic and atmospheric phases become amenable to nonlinear analysis. Along the way, the presence of critical phases and transitions are indeed seen in effect. When this general endeavor began two decades ago, akin to quantum realms, weather and climatic phases seemed so intricate and intractable they would daunt any analytical attempt. As the first Abstract sentence states this worldwild realm is now included amongst nature’s universal recurrence. See also Stochastic Resonance for Non-Equilibrium Systems by V. Lucarini at arXiv:1910.05048.

The climate system is a forced, dissipative, nonlinear, complex and heterogeneous system out of thermodynamic equilibrium with a natural variability on many scales of motion in time and space. This paper reviews observational evidence on climate phenomena and governing equations of planetary-scale flow. Recent advances in the application of dynamical systems theory and nonequilibrium statistical physics are brought together help understand and predict the system’s behavior. These complementary views permit a self-consistent handling of subgrid-scale phenomena as stochastic processes, as well as a unified handling of natural climate variability and forced climate change.

Selvam, Amujuri Mary. Self-Organized Criticality and Predictability in Atmospheric Flows: The Quantum World of Clouds and Rain. International: Springer, 2017. The senior physicist author is deputy director of the Indian Institute of Tropical Meteorology in Poona. As the quote says, the volume is a sophisticated, exemplary witness that even hyper-active complex weather phenomena can be found to reside in nature’s universally preferred state.

This book presents a new concept of General Systems Theory and its application to atmospheric physics. It reveals that energy input into the atmospheric eddy continuum, whether natural or manmade, results in enhancement of fluctuations of all scales, such as the high-frequency fluctuations of the Quasi-Biennial Oscillation and the El-Nino–Southern Oscillation cycles. These atmospheric flows then exhibit a self-organised criticality via long-range spatial and temporal correlations which manifest as fractal self-similar patterns with an inverse power law form. Since the probability distributions of amplitude and variance are the same, atmospheric flows exhibit quantum-like chaos. Long-range correlations inherent to power law distributions of fluctuations are identified as nonlocal connection or entanglement exhibited by quantum systems such as electrons or photons.

Alsharif, Mohammed, et al. Sixth Generation (6G) Wireless Networks: Vision, Research Activities, Challenges and Potential Solutions. Symmetry. 12/4, 2020. An international team posted in Korea, Nigeria, Oman, Turkey, and Pakistan scope out this new hyper-dimensional worldwise knowledge transmission system. By order of magnitude advances and reach it promises ever faster speeds and content capacity. Once again, our premise is that this noosphere, conceived a century ago by V. Vernadsky and P. Teilhard, into the 21st century is manifestly coming to its (her/his) own knowledge and revolutionary discovery.

The standardization activities of fifth generation communications are clearly over and deployment has commenced globally. To sustain the competitive edge of wireless networks, industrial and academia synergy have begun to conceptualize the next generation of wireless systems (sixth generation, 6G) aimed at laying the foundation for communication needs of the 2030s. In support, this study highlights promising lines of research from the recent literature for the 6G project. Thus, this article will contribute significantly to opening new horizons for future research directions. (Abstract excerpt)

Makey, Ghaith, et al. Universality of Dissipative Self-Assembly from Quantum Dots to Human Cells. Nature Physics. 16/7, 2020. A 15 member project at the National Nanotechnology Research Center and Institute of Materials Science, Bilkent University, Ankara, Turkey well quantifies nature’s deep autocatalytic, self-organizing propensities from quantum to organic cellularity. These constant processes across a wide domain is then seen to express a universal repetition in kind. The work merited a review Dissipate Your Way to Self-Assembly by Gili Bisker (Tel Aviv University) in the same issue. So at the same while that the Hagia Sophia (holy wisdom) is reverting back to a mosque, Turkish scientists, whose achievement is praised by a Jewish woman, contribute and look forward to a new common creation.

An important goal of self-assembly research is to develop a general methodology applicable to almost any material, from the smallest to the largest scales, whereby qualitatively identical results are obtained independently of initial conditions, size, shape and function of the constituents. Here, we introduce a dissipative self-assembly methodology demonstrated on a diverse spectrum of materials, from simple, passive, identical quantum dots (a few hundred atoms) that experience extreme Brownian motion, to complex, active, non-identical human cells (~1017 atoms) with sophisticated internal dynamics. Autocatalytic growth curves of the self-assembled aggregates are shown to scale identically, and interface fluctuations of growing aggregates obey the universal Tracy–Widom law. (Abstract)

Haqq-Misra, Jacob, et al. Observational Constraints on the Great Filter. arXiv:2002.08776. We cite this entry by Blue Marble Space Institute, and NASA Goddard astroscientists becauses it identifies a bottleneck or check point that a planetary to cosmic civilization must successfully pass through. The abstract and quote discuss its various straits and where the certification barrier might be. It is then alluded that for an apocalyptic Earth-like bioworld, the critical condition may be whether the emergent transition to a unified personsphere progeny can be accomplished. In specific regard, our 2020 introduction is considers the presence of some kind of second singularity event.

The search for spectroscopic biosignatures with the next-generation of space telescopes could provide observational constraints on the abundance of exoplanets with signs of life. Current mission concepts that would observe ultraviolet to near-infrared wavelengths could place upper limits on the fraction of planets in the galaxy that host life. We note that searching for technosignatures alongside biosignatures would provide important knowledge about the future of our civilization. If technical civilizations are found, then we can increase our confidence that the hardest step in planetary evolution--the Great Filter--is probably in our past. But if we find life to be common but nothing else, then this would increase the likelihood that the Great Filter awaits to challenge us in the future. (Abstract excerpt)

Resolving the Great Silence (no one there) carries implications for the future of technological civilization on Earth. The apparent absence of extraterrestrials suggests that there is an improbable evolutionary step somewhere from the origin of life to galactic settlement. (Robin) Hanson (1998, mason.gmu.edu/~rhanson/greatfilter) called this the “Great Filter” for an inhibitory step in evolution. If the origin of life is rare, then this would explain the lack of abundant life on nearby planets, with the Great Filter in our past. But Hanson also pointed out that “evidence of extraterrestrials is likely bad news” because this would mean a Great Filter awaits in our future. If the galaxy were teeming with complex life, and even civilizations, then this would suggest that the evolution of life until today have been relatively benign. This means that the Great Filter is in our future, somehow with regard to our current technological state. (3, edits)

Raymond, Sean, et al. Solar System Formation in the Context of Extrasolar Planets. Meadows, Victoria, et al, eds. Planetary Astrobiology. Tempe: University of Arizona Press, 2020. SR, University of Bordeaux, with coauthors Andre Isidora, Sao Paulo State University and Alessandro Morbidelli, University of Nice astrophysicists (search SR, AM) are leading expositors of the arduous, stochastic formation of stellar objects and their myriad rocky, gaseous, oceanic, icy, arid orbital worlds. Two decades into the 21st century, stars and planets have been found across every possible size, shape and kind as they traverse solar systems and fill diverse galaxies. In regard, sun and bioworld are coming to appear as unitary incubators for evolutionary habitation. But another august finding has grown in evidential veracity, whence our home system and planet Earth is a rarest optimum confluence by way of passing through many critical check-points, as this section reports.

Exoplanet surveys have confirmed one of humanity’s worst fears: We are weird. If our solar system were observed with present-day Earth technology — to put our system and exoplanets on the same footing — Jupiter is the only planet that would be detectable. The statistics of exo-Jupiters indicate that the solar system is unusual at the ~1% level among Sun-like stars (or ~0.1% among all main-sequence stars). But why are we different? This review focuses on global models of planetary system formation. Successful formation models for both the solar system and exoplanet systems rely on two key processes: orbital migration and dynamical instability. Systems of close-in “super-Earths” or “sub-Neptunes” cannot have formed in situ, but instead require substantial radial inward motion of solids either as drifting millimeter- to centimeter-sized pebbles or migrating Earth-mass or larger planetary embryos.

Reinhold, Timo, et al. The Sun is Less Active that Other Solar-like Stars. Science. 368/516, 2020. A seven person team with postings in Germany, Korea, and Australia find that our starry sun to have a relatively benign magnetic field compared to a majority of similar solar types. Since higher magnetic activity may be averse to habitability, here may still be another feature that favors our home Earth.

The magnetic activity of the Sun and other stars causes their brightness to vary. Here, we investigate how typical the Sun’s variability is compared with other solar-like stars. By combining 4 years of photometric observations from the Kepler space telescope with astrometric data from the Gaia spacecraft, we were able to measure photometric variabilities of 369 solar-like stars. Most of those with well-determined rotation periods showed higher variability than the Sun and are considerably more active. These stars appear nearly identical to the Sun except for their higher variability. (Abstract)
