Artistry

I am an artist in Karma
Sometimes successful
Often a failure
The canvas of my artistry
Is life itself
A composition
Of timing, thought and serendipity
That streams
Through the chaos and eddies
Of our times
Momentarily seen
Like glints of moonlight
On nighttime ripples of ocean
Otherwise faded into shadows
Of inalert distracted infantile
Naïve societal attention
Particular to my unique experience
Archetypal in its everyman generality
A flicker in human history
Like the flash of a red wing
Penetrating through a forest mist
Out of sight
The briefest part of a second
In one of countless infinite
Pulses of living Earth’s life
The heartbeat of the Universe
As instance of vibrance
In one miniscule organic expression
Of that fathomless total Immensity
A vibration passed among us all
As a sharing of existence

My art is to know that this is so
And to reflect on my immersion
In ripples of consciousness
That recede from my particularity
Crossing other rings of experience
Fanning out
From life-forms seen and unseen
Joys and struggles known and unknown
Awakenings and sleepenings
Scintillating the all-pervading
Field of thought and thoughtlessness
That forms the ocean
On which we each and all journey

This is my art
And I alone as Universe
Am free to behold it.

Book and Movie Reviews by MG,Jr. (2017-2020)

1 August 2020, was the 201st anniversary of the birth of Herman Melville. 2019 was my year to be totally immersed in Moby-Dick (for the third time), an awesome masterpiece. This is PERHAPS, the greatest novel yet written in the English language.

I’ve written previously on Melville and Moby-Dick here:

Three movies from 2015-2016:

Heal the Living (Réparer les vivants) (2016)

Superb film by Katell Quillévéré (screen-writer and director), about life, death and organ donors. The meditative nature of this film, without excessive pathos, with a lovely piano accompaniment (most of the time except for two noisy rock songs), the lovely crisp photography possible with today’s equipment, and its seamless transitions between wakeful reality and introspective day-dreaming, and back, and its transitioning ensemble – constellation – of collaborative actors (instead of a star in front of background “support”), make this a very thoughtful and artistic film that presents fundamental truths. All these sterling qualities (except for the crisp photography) will make this film largely unpopular for US audiences, especially when spoken in French with English subtitles.
https://youtu.be/otYWveDaplo

Genius (2016)

A superb English film about legendary American authors, particularly Thomas Wolfe (author of “Look Homeward, Angel”) and really about Max Perkins, the Scribner’s (book publishing company) editor who discovered Ernest Hemingway, F. Scott Fitzgerald and, most flamboyantly, Thomas Wolfe (the movie is ostensibly about him). The heart of the story is about friendship (male friendship) collaborating in the creative artistic process, in this case to produce literary novels. Anyone who likes reading (actual books of literature, in paper), and who strives to produce excellent art that requires collaborators (particularly theater and often music, and inevitably every art) in any medium would like this movie. However, the American reviewers were not keen on this movie because they and most American audiences don’t really like reading and find the movie “slow;” it’s basically a detailed exposition of intellectual processes (and what American wants to watch that?); its lighting is “dark” (which is how it actually looks in downtown Manhattan); Americans don’t like foreigners making movies about American subjects (English actors can do any variety of American accents, but American actors can’t do English, or any other foreign accent); and the movie unrolls like a well thought-out play since it was in fact directed by an English theatrical director (with a story based on a carefully studied biography of Max Perkins).
https://youtu.be/gCvcD3IBSlc

Mr. Holmes (2015)

This is a modern and very clever modern story (i.e., not by Arthur Conan Doyle) of Sherlock Holmes near the end of his life in retirement, living as a beekeeper. The plot, photography, score, and acting by the (largely) English cast are all first rate, naturally. The film has proved popular with English and American audiences, and rightfully so. The story involves Holmes as a 93-year-old (in ~1947) who, despite failing memory, is trying to recall the details of his last case, which ended tragically and caused him to retire. The jumps between “the present” (~1947) and flashbacks (~1912) are clear, as are the transitions to the flashbacks to Holmes’s post WWII visit to Japan (1946/1947). There is enough of the “solve the mystery” element in the film to satisfy most Sherlock Holmes fans, and a thoughtful emotional-psychological thread to the story that was not ruined by an excess of pathos or icky sweetness. Of course the acting, photography and score were good and well-integrated into this polished work of cinema. Overall, nicely paced and good entertainment with wit, polish and good heart.

Lafcadio Hearn

Lafcadio Hearn (1850-1904) was an unusual American who eventually became a Far Eastern foreign correspondent to American newspapers and magazines, and an expert interpreter of Japanese and Chinese stories, legends and fables, as well as a keen observer of how life was conceptualized and conducted in Asia (mainly Japan).

Lafcadio Hearn was born in Lefkada, a Greek island in the Ionian Sea on the west coast of Greece. He had an Irish father and Greek mother, and a difficult childhood filled with rejection. He also lived a very unusual life, for some time a newspaper crime reporter in the U.S.A. (Cincinnati, New Orleans), marriage to a Black Women at a time when mixed marriages were extremely difficult to sustain socially in the U.S., and then moving on to a foreign correspondent role, first in the French West Indies and then in Japan. There, he learned Japanese, taught in Japanese schools, married a Japanese woman and had four sons, and lived out a happy last chapter to his colorful and literary life.

A superb book by Hearn is Kwaidan, which is a book of Japanese ghost stories, and which book was the basis of an amazing 1965 Japanese art film (movie) of the same title by Kobayashi. I think Kwaidan is a masterpiece.

Gleanings In Buddha Fields is a collection of stories (the mythical, legendary and fabulous) and essays (on the realities of life), which in total immerse the reader into the zeitgeist, or context, of late 19th and early 20th century Japan.

Alan Watts noted that Lafcadio Hearn’s book Gleanings In Buddha Fields (1897) sparked (or was one of the sparkers of) his interest in Buddhism and Eastern Philosophy. I read Gleanings In Buddha Fields because I was curious to learn the source (about one of the sources) of where Alan got his Zen.

I recommend Gleanings in Buddha Fields to you (and Kwaidan).

Because some (at least one or two) of Hearn’s references to historical personalities of 19th century (and earlier) Japan are not part of modern memory, you might have to do a little Internet researching to gather some of the historical facts about the incidents Hearn was referring to (in Gleanings…), in order to fully appreciate Hearn’s presentation. But even without such deeper investigation, Gleanings In Buddha Fields is an excellent, informative, thoughtful and Zen-atmospheric book. In discovering it with your first reading, you can also imagine yourself reliving, at least in part, the juvenile awakening to Zen Buddhism experienced by Alan Watts (whose The Way of Zen is a masterpiece).

A modern collection of selected Japanese stories (including some from Kwaidan) by Hearn is the following. It is excellent, and well-researched, with a very informative introductory essay by the editor-researcher, who was Ireland’s ambassador to Japan.

All Quiet On The Western Front

“All Quiet On The Western Front,” by Erich Maria Remarque (22 June 1898 – 25 September 1970), is the greatest war novel of all time. Why? Because it vividly conveys the physical, psychological and emotional realities of being at the front face-to-face with the enemy in an all-out massively industrialized war. “All Quiet On The Western Front” is also the greatest anti-war novel of all time. Why? Because it vividly conveys the physical, psychological and emotional realities of being at the front face-to-face with the enemy in an all-out massively industrialized war.

This novel was first published 92 years ago, in 1928; and its story is set a century ago, in 1918, during World War I. This novel describes the realities of a soldier’s transformation from naïve enthusiastic recruit to hardened emotionally vacant veteran, the deadly and depersonalizing confusion of military operations, the rush and terror of frontline combat, the haphazard allocation of injuries, the slow-motion dread of being in hospital, the brief joys and overwhelming alienation and anguish of home leave, the struggle against insanity, the scant and fleeting serendipitous joys in the field, the loss of a personal past that moored one to a potentially fulfilling future in one’s culture, and the crushing of the lonely human spirit shadowed by the omnipresence of death. The human reality of this novel is timeless. Most of us casually say we are anti-war, but to truly inoculate yourself against any taste for war you must read this book and allow its story, and its feeling, to soak deep into your psyche.

F. Scott Fitzgerald

Fitzgerald’s novel Tender Is The Night hit me like a thunderbolt. Fitzgerald drew the title from a line in John Keats’s poem “Ode to a Nightingale.” I’ve written quite a bit about Fitzgerald (follow the links to that). Below are a few of the comments about Fitzgerald and movies about him and his novels.

I Learn About F. Scott Fitzgerald
https://manuelgarciajr.com/2019/03/16/i-learn-about-f-scott-fitzgerald/

Two “F. Scott Fitzgerald” movies:

Last Call is based on the memoirs of Frances Kroll Ring (1916-2015), Fitzgerald’s last secretary, and sounding board, to whom he dictated his last novel The Love Of The Last Tycoon, A Western. Frances Kroll Ring’s book (1985), highly praised by both scholars and Fitzgerald aficionados for its accuracy, detail and sympathy, is about the last two years (1939-1940) of Fitzgerald’s life. Frances Kroll Ring (herself in 2002) appears at the end of the film. A very well made film, as close as we’ll ever get to “being there” with Scott. Jeremy Irons plays Scott, Neve Campbell plays Frances Kroll Ring, both excellently in my opinion. The Cambridge Companion To F. Scott Fitzgerald (2002) is dedicated to Frances Kroll Ring “with affection, gratitude, and respect from everyone who reveres F. Scott Fitzgerald as man and artist.”

Getting Straight is a fun movie of college life and protest in 1970, and centers on a much put upon ex-activist and graduate student of literature (“Harry,” played by Elliot Gould) who ultimately gives it all up (except the girl) in a very spirited defense of the art and spirit of F. Scott Fitzgerald. This movie was approvingly pointed out by Ruth Prigozy, the editor of The Cambridge Companion To F. Scott Fitzgerald. I was surprised at how many references Harry makes to characters and incidents in both Fitzgerald’s novels and in his life (with Zelda and then Sheilah Graham). The movie can be fun without having to know all these references, but it is much funnier being in the know. I thought, my god!, this bright, breezy, light-hearted confection from 1970 would be over the heads of the illiterate comic-book-cartoon-movie-consuming popular audiences of today: we’re doomed!

The Moment F. Scott Fitzgerald Knew He Was a Failure
By Lili Anolik
Sep 22, 2015
https://www.esquire.com/entertainment/a38113/f-scott-fitzgerald-1015/

“It was a gorgeous evening. A full moon drenched the road to the lustreless color of platinum, and late-blooming harvest flowers breathed into the motionless air aromas that were like low, half-heard laughter.”
— F. Scott Fitzgerald, from The Curious Case Of Benjamin Button, section V.

“The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.”
— F. Scott Fitzgerald, from The Crack-Up, part I, 1936

My Wicked, Wicked Ways, by Errol Flynn

A mostly honest book. I have always loved Flynn in the movies. A very engaging character, with his own flaws and tragedies despite all the glamour and antics. What I most like about him is that despite everything, he always sought to enjoy, to laugh, to be happy and make others happy; but a major prankster.

I think he knew he was doomed to a short life from very early on; he had contracted tuberculosis and malaria as a teenager prospecting in New Guinea in the late 1920s very early 1930s. So, he enjoyed his smokes and booze and morphine, and most of all women, who shamelessly threw themselves at him, especially after he made money but even before when broke and homeless. Besides, he pursued them very keenly, too.

Alan Watts mentioned that some Zen master from the past had said that there were two paths to enlightenment: the path of thoughtful study, meditation, good works, piety, humility and patience; and the path of debauchery leading to exhaustion of that attitude leading in turn to an awakening. This in fact is the main comparison presented in Herman Hesse’s Siddhartha. But, Watts continued, the first path is by far recommended even though its “success rate” is not particularly high, because the second path can easily be fatal (in every way) though it was considered a “sure thing” and “quicker” for gaining enlightenment: if you survived to getting to that point! The story of Siddhartha Gautama (Buddha) is in fact of a life of renunciation of a princely life of luxury and dissipation to first seek meaning through asceticism, which was ultimately found to be arid, and then to settle on the “middle way,” between asceticism and dissipation: which for today we can think of as consumerist materialism (dissipation, that is).

So, Flynn’s book was fun for me to help reflect on these ideas. Besides, it is a fun book on vignettes and quips about “golden age” Hollywood.

Errol Flynn starred in the 1938 movie, The Dawn Patrol, about WWI British fighter pilots in France. This is an anti-war movie. I describe it here:

<><><><><><><>

Magister Ludi (The Bead Game)

Herman Hesse received the Nobel Prize for Literature for Magister Ludi (The Bead Game). Interesting book (long), but sometimes a bit remote/slow for me. The “three tales” appended at the end are superb. I wonder if the whole big book before it was really just an enormous lead-in to them. Hesse put tremendous thought and work into this book, there are many undercurrents and subtleties that I may not have fully appreciated. I think it is basically a book about religious feeling (existentialism?) in a non-religious way; similar to the orientation of Carl G. Jung’s psychology. Both Jung and Hesse were born in religious/missionary families from Switzerland (Jung) or southwest Germany near Switzerland (Hesse, who spent much of his life till the end in Switzerland). I think Hesse was working from a view of life like looking at the Swiss Alps from a remote chalet (which is in fact where he lived).

Excerpts from Magister Ludi (The Bead Game), (1943)

He had also made the discovery that a spiritual man in some curious way arouses resentment and opposition in others, who esteem him from afar and make claims on him in times of distress, but by no means love or look upon him as one of themselves and are more inclined to avoid him. He had learned from experience that old-fashioned or home-made magic formulas and spells were more willingly acceptable to sick people or victims of misfortune than intelligent advice. He had learned that man prefers misfortune and external penance rather than attempt to change himself inwardly, and had found that he believed more easily in magic than in intelligence, and in formulas more readily than in experience — many things in fact which in the few thousand years that have elapsed have presumably not altered so much as many history books would have us believe. He had also learned that a man in quest of the spiritual should never abandon love, that he should encounter human desires and follies without arrogance, but should, however, never allow them to dominate him; for, from the sage to the charlatan, the priest to the mountebank, from the helping brother to the parasitical sponger, is only a short step, and people fundamentally prefer to pay a rogue or allow themselves to be exploited by a quack than to accept selflessly offered assistance for which no recompense is asked. They would not readily pay with confidence and love, but preferably with gold or wares. They cheated each other and expected to be cheated in return. One had to learn to regard man as a weak, selfish and cowardly being, but one had also to see how greatly one participated in all these characteristics and urges and longs for ennoblement.

We must no longer rely on the fact that the cream of the talented from out there flock to us and help us to maintain [our society]: we must recognise our humble and heavy responsibility to the schools of the world as the most important and the most honourable part of our task, and we must elaborate it more and more.

Times of terror and the deepest misery may arrive, but if there is to be any happiness in this misery it can only be a spiritual happiness, related to the past in the rescue of the culture of early ages and to the future in a serene and indefatigable championship of the spirit in a time which would otherwise completely swallow up the material.

Siddhartha

I love “Siddhartha” by Hesse; easy to see why that book of his is so popular. It is an “awakening” story similar to the life of Buddha, who appears as a support character to the protagonist. I said more about “Siddhartha” in my comments on Errol Flynn, above.

After The End of The World: books by George R. Stewart, and Walter M. Miller, Jr.

Here are two classic “after the end of the world” books. In Earth Abides, George R. Stewart’s end-of-the-world is by pandemic!, and in A Canticle for Leibowitz, Walter M. Miller Jr.’s is by post nuclear war taking America back to a Medieval Period, and then eventually over a few millennia to a new rocket and nuclear age, which ends as one would expect.

Stewart was an English professor at the University of California, Berkeley, in the 1930s-1940s, and his book here is from 1949. Amazingly prescient, realistic “speculative fiction” about the subsequent lives of the few survivors of the nearly overnight pandemic.

Miller’s book is definitely different, but there are no cheesy sci-fi gadgetry nor “special effects,” despite the strangeness of the worlds he portrays. Interestingly, the monastery life that is the center of Miller’s book is similar in many ways to the monastery life that is the center of Herman Hesse’s Magister Ludi (which is also a sort-of after the end of the world book, really of a “distant” future after the end of the fascist world).

I cannot imagine Miller’s vision becoming reality, but I can easily imagine Stewart’s coming about.

The Twilight Zone

A PERSONALLY IMPORTANT LIFE GOAL OF MINE MET!

During this 2020 summer of hiding out from the pandemic, I watched all 156 episodes of the anthology TV show, THE TWILIGHT ZONE, which originally ran between 1959 and 1964. This feat was accomplished by seeing 2 to 6 episodes a night on consecutive nights over the course of several weeks.

This show is a collective work of TV art, guided by Rod Serling, who wrote 59% of the episodes. Amazingly, despite this show being in the neighborhood of 60 years old, its anachronisms relative to today’s typical attitudes and technological paraphernalia are infrequent (as regards the attitudes) and not distracting (as regards the technicalities). But it really shines in its depiction of the inner workings of human hearts and minds, and also human heartlessness. In this most important artistic-literary aspect, The Twilight Zone has not been surpassed by television shows since.

The Twilight Zone is a sequence of — usually — morality tales (interspersed with occasional comedies) whose telling is freed imaginatively and dramatically by allowing for the arbitrary actions of mysterious metaphysical forces. It’s as if Lafcadio Hearn, Ambrose Bierce and H. P. Lovecraft had been transported 60 years into their futures to write for television. One of the most thrilling aspects of Rod Serling’s Twilight Zone is the intense social consciousness, and anti-war, anti-greed, anti-bigotry and anti-cruelty attitudes nearly every minute of the entire series exudes. The acting, by many many actors, is uniformly excellent; and the production values of all the technicalities are also very good, but also very obviously more modest than in the costly productions of TV fare today.

In seeing the entire 156 episodes in one concentrated period of time, I have gotten a very clear appreciation of The Twilight Zone’s beauty and value as art. Without intending to be blasphemous, pretentious or dumb, let me say that I can see The Twilight Zone representing, for discerning American (and beyond?) viewers of the 1960s, a thought-provoking and socially instructive film-electronic art form in the same way that the plays of Sophocles, Euripides and Aristophanes were thought-provoking and socially instructive theatrical art forms to the Fifth-century Athenians.

The bubbling cauldron of social tensions, aspirations and fears of dynamic yet troubled societies were artistically abstracted and polished into the diamond-sharp facets of intense dramatic plays, reflecting the whole of contemporary society back into itself through the fascinated gaze of its individual people. If “the eyes are the mirror of the soul” then The Twilight Zone, through TV screens, was the mirror of the collective or societal American soul, which soul is always hidden behind a flashy loud and positivist front.

If you see the whole series, looking past the incidentals of its presentation, but deep into the essence of its conception, literateness and soul, you will see and hear as sharp and accurate depictions of the personalities and preoccupations of our society today as was the case for the American society of the early 1960s, during the show’s first run 61 to 56 years ago.

John Keats, poet

Much feeling here, combined with a tremendous amount of work to present that feeling with refinement and grace of language, without dilution of the emotion, and without making it all seem a labored construction. Also wonderful feeling for nature and the natural world. I can’t criticize anything here, only try to learn from it. To my mind, Keats is to English poetry what Mozart is to music. Keats was a major influence on F. Scott Fitzgerald, who I see as an American “3rd generation” English Romantic poet who expressed his artistry in prose.

I have to dig into Shelley next (I have a huge tome), who was more “ferocious” than Keats. Both were very focussed artists. I’m struck by the idealism they felt and worked from.

In Pursuit of the Unknown: 17 Equations That Changed the World, by Ian Stewart

Hello math lovers! (sic),

At one time or another a member of my family or friends has expressed an interest in:

Pythagoras’s Theorem (triangles, distance, areas, surfaces), or

Calculus (rates of change of anything and everything), or

Newton’s Law of Gravity (planetary motion, satellite trajectories), or

Pure Math (Napier’s Bones, the weirdness of the square root of -1, and Möbius Strip topology), or

Normal Distribution (the probability distribution of IQ, and “The Bell Curve” book), or

The Wave Equation (tones, semitones, musical scales, even tempering, beats within harmony), or

Fourier Transform (sines and cosines, single frequency/pitch modes and equalizers, digital camera images), or

The Navier-Stokes Equation (fluid flow, aerodynamics, F1 car design, global warming computation), or

Maxwell’s Equations (electricity, magnetism, radiation, wireless communication, TSA body scanners), or

Thermodynamics (entropy, efficiency of engines and renewable energy technology, disordering of the universe), or

Relativity (curved space-time, bent light rays, black holes, Big Bang, dark matter, dark energy), or

Quantum Mechanics (Schrödinger’s Cat, many parallel worlds, semiconductor electronics), or

Information Theory (codes, coding, data compression, digital communications), or

Chaos (species population dynamics with explosive growth and collapse, erratic unpredictability), or

Black-Scholes Equation (insane financial speculation, options, futures, derivatives, credit default swaps, the banking/real estate/financial crash of 2007-2008).

Because of that, here is my review of Ian Stewart’s 2012 book: In Pursuit of the Unknown: 17 Equations That Changed the World. Stewart says of his book: “This is the story of the ascent of humanity, told through 17 equations.”

This is an excellent enthralling book: interesting, very informative, very well written clear explanations of the mathematics and the applications of that mathematics to: classical mathematical calculations, lots of physics and related technology, information theory (codes and computers), chaos (wild swings in species populations), and the insane 21st century finance economics of our previous financial crash and its inevitable successors. This brief description does not in any way convey the complete range of this book.

On the front cover you can see the 17 (sets of) equations, which Stewart describes (and their many uses) over the course of 17 chapters. Of the 13 equations I feel confident about knowing something about (all “basic” math and/or mathematical physics), I find Stewart to be accurate and masterfully clear in his descriptions.

My only quibble is where he states about the main causes of global warming being the production of carbon dioxide and methane (gases) that: “These are greenhouse gases: they trap incoming radiation (heat) from the Sun.”

This is a collapsing of the actual mechanism, which is: the the capture of outgoing heat radiation (infrared radiation) by CO2 (most importantly) and CH4 (along with other heat-trapping molecular gases in trace amounts in the atmosphere), which upward radiated heat energy is derived from the earlier absorption (by the oceans and lands) of incoming light energy; a necessary process for cooling the Earth and stabilizing its temperature (if we didn’t mess with the process). So I would rephrase the Stewart sentence quoted as: “These are greenhouse gases: they trap outgoing radiation (heat) from the Earth.”

[If you think about it you will see that wherever the biosphere captures the incoming LIGHT from the Sun — in the air, lands or oceans — it ultimately heats to the same degree; but when our pollution intercepts and stores a greater portion of the re-radiated outward going HEAT (infrared radiation) from the biosphere than would be the case “naturally,” that the Earth’s “cooling system” is impaired and the biosphere warms up steadily, for an Earth out of heat balance.]

Regardless of this quibble, Stewart knows much much more about all the mathematics he presents and all the uses of it than I do. The 4 equations I knew nothing about (and learned about from Stewart) are: #1 Euler’s formula for polyhedra (topology); #2 information theory; #3 chaos theory (I know a little a bit about nonlinear dynamics, sensitivity to initial conditions, and limit cycles: similar to the “butterfly effect”); and #4 the Black-Scholes, or “Midas” equation that was heavily abused to produce the financial meltdown of 2007-2008. On these four, I learned a great deal from Stewart (basically everything I know about them now), and in the reading of this book I gained a sense of trust in his descriptions and pronouncements.

My only other critique of the book (and a minor one) is that there are a number of proofreading lapses (both of text and substance) that show up as typographical errors, and/or what I presume to be mischosen words (some obviously errors, others didn’t make sense to me). The few instances of these errors occur most frequently in the later chapters of the book, and none is fatal (especially if you don’t notice them). So, I agree with the praise for the book highlighted on the back cover.

I especially recommend the book for its explanation (in 8 chapters) of the physics of: classical gravity (Newtonian mechanics), waves, heat flow, fluid flow, electrodynamics, thermodynamics (entropy), relativity and quantum mechanics. I also appreciate his logical and scathing take-down of the modern hyperactive derivative-based financial speculation that dominates and threatens the world’s economies today. For me, the 8 physics chapters are superb; but there is no part of the book that is weak: “a wonderfully accessible book.”

Upanishads

Juan Mascaró was a superb poetic translator. His selections from the Upanishads is enthralling. His translation of the Dhammapada was also wonderful:

“As the bee takes the essence of a flower and flies away without destroying its beauty and perfume, so let the sage wander in this life.” — The Dhammapada, 49

Ocean Heat, From the Tropics to the Poles

The heat being captured by the increasing load of carbon dioxide and other greenhouse gases in the atmosphere is subsequently transferred into the oceans for storage. This process — global warming — has raised the temperature of the biosphere by 1°C (or more) since the late 19th century.

Heat introduced into any material body at a particular point will diffuse throughout its volume, seeking to smooth out the temperature gradient at the heating site. If heat loss from that body is slow or insignificant, then a new thermal equilibrium is eventually achieved at a higher average temperature.

Thermal equilibrium does not necessarily mean temperature homogeneity, because the body may have several points of contact with external environments at different temperatures that are held constant, or with other external thermal conditions that must be accommodated to. Equilibrium simply means stable over time.

The heat conveyed to the oceans by global warming is absorbed primarily in the Tropical and Subtropical latitudes, 57% of the Earth’s surface. The Sun’s rays are more nearly perpendicular to the Earth’s surface in those latitudes so they receive the highest fluxes of solar energy, and oceans cover a very large portion of them.

That tropical heat diffuses through the oceans and is also carried by ocean currents to spread warmth further north and south both in the Temperate zones (34% of the Earth’s surface) and the Polar Zones (8% of the Earth’s surface).

What follows is a description of a very idealized “toy model” of heat distribution in the oceans, to help visualize some of the basics of that complex physical phenomenon.

Heat Conduction in a Static Ocean

The model is of a stationary spherical globe entirely covered by a static ocean of uniform depth. The seafloor of that ocean is at a constant temperature of 4°C (39°F), the surface waters at the equator are at 30°C (86°F), and the surface waters at the poles are at -2°C (28°F). These temperature conditions are similar to those of Earth’s oceans. These temperature boundary conditions are held fixed, so an equilibrium temperature distribution is established throughout the volume in the model world-ocean. There is no variation across longitude in this model, only across latitude (pole-to-pole). (See the Notes on the Technical Details)

Figure 1 shows contours of constant temperature (isotherms) throughout the depth of the model ocean, from pole to pole. The temperature distribution is shown as a 3D surface plotted against depth, which is in a radial direction in a spherical geometry, and polar angle (from North Pole to South Pole).

Figure 2 is a different view of the temperature distribution. Three regions are noted: The Tropical Zone (from 0° to 23° of latitude, north or south) combined with the Subtropical Zone (from 23° to 35° of latitude, north or south); the Temperate Zone (from 35° to 66° of latitude, north or south); and the Polar Zone (from 66° to 90° of latitude, north or south).

The model temperature distribution is perfectly stratified — isotherms uniform with depth — in the Tropical-Subtropical Zones, from 30°C at the surface at the equator, to 4°C at the seafloor. On entering the Temperate Zones, the isotherms arc up into a nearly radial (vertical) orientation. In the small portions of the planetary surface covered by the Polar Zones the isotherms are now more horizontally stratified because the surface waters are chillier that the those at the seafloor.

Figure 3 shows the streamlines of heat flow (the temperature gradient) for this temperature distribution. At the equator the heat is conducted down from the 30°C surface to the 4°C seafloor. As one moves further away from the equator the streamlines become increasingly lateral, until they are entirely so at 35° of latitude (north or south) where the model surface waters are at 19°C. The heat flow is entirely horizontal at this latitude, which separates the Subtropical and Temperate Zones; tropical heat is being conducted laterally toward the poles. In the Polar Zones the heat flow is up from the lower depths because the surface waters are chiller than those at depth, and because there is too little temperature variation with distance along the surface to drive a lateral heat flow.

Thermally Driven Surface Currents

Much oceanic heat is distributed by currents, and many of these occur along the surface.

The average speed of the Gulf Stream is 6.4km/hr (4mph), being maximally 9kph (5.6mph) at the surface but slowing to 1.6kph (1mph) in the North Atlantic, where it widens (information from the National Oceanic and Atmospheric Administration, NOAA).

Heat-driven equator-to-poles surface currents on the model ocean were estimated from the combination of the pole-to-pole surface temperature distribution, and thermodynamic data on liquid water. (See the Notes on the Technical Details)

The pressure built up by tropical heat in the model ocean’s equatorial waters pushes surface flows northward (in the Northern Hemisphere) and southward (in the Southern Hemisphere): from a standstill at the 30°C equator; with increasing speed as they recede from the equator, being 2kph (1.3mph) where the surface waters are at 25°C (77°F); a continuing acceleration up to a speed of 2.8kph (1.7mph) at the 35° latitude (the boundary between the Subtropical and the Temperate Zones); and an ultimate speed of 3.6kph (2.2mph) at the poles.

The currents are converging geometrically as they approach the poles, so a speed-up is reasonable. Logically, these surface currents are legs of current loops that chill as they recede from the equator, plunge at the poles, run along the cold seafloor toward the equator, and then warm as they rise to the surface to repeat their cycles.

An equator-to-pole average speed for these model surface currents is 2.8kph (1.7mph). Their estimated travel times along the 10,008km surface arc (for a model world radius of 6,371km, like that of a sphericalized Earth) is 3,574 hours, which is equivalent to 149 days (0.41 year).

Greater Realities

The model world just described is very simple in comparison to our lovely Earth. Since it does not rotate, it does not skew the north-south flow of currents that — with the help of day-night, seasonal, and continental thermodynamic inhomogeneities — creates all of the cross-longitudinal air and ocean currents of our Earth.

The irregularity of seafloor depth on Earth also redirects cross-latitudinal (pole-to-pole) and cross-longitudinal bottom currents, as do the coastlines of the continents; and the very slight and subtle changes in seawater density with temperature and salinity — neither of which is distributed uniformly throughout the body of Earth’s oceans — also affect both the oceans’s volumetric temperature distributions, and the course of ocean currents.

Recall that the model ocean is bounded by constant imposed temperature conditions at its seafloor (4°C) and surface waters (a particular temperature distribution from 30°C at the equator, to -2°C at the poles). Since this model world is otherwise suspended in a void, if these boundary conditions were removed the oceanic heat concentrated at the equator would diffuse further into the watery volume, seeking to raise the temperatures of the poles and seafloor while simultaneously cooling the equatorial region. The ultimate equilibrium state would be an ocean with a constant temperature throughout its volume.

Additionally, if it is also assumed that the now “liberated” model ocean-world can radiate its body heat away — as infrared radiation into the void of space — then the entire planet with its oceanic outer shell slowly cools uniformly toward -273.16°C (-459.69°F), which is the “no heat at all” endpoint of objects in our physical Universe.

When our Earth was in its Post-Ice Age dynamic thermal equilibrium, the “heat gun” of maximal insolation to the Tropics and Subtropics warmed the oceans there; a portion of that heat was conducted and convected into the Temperate Zones and toward the Poles; where the “ice bags” of masses of ice absorbed seasonal oceanic heat by partially melting — which occurs at a constant temperature — and then refreezing. Also, the atmosphere did not trap the excess heat radiated into space. In this way cycles of warming and cooling in all of Earth’s environments were maintained in a dynamic balance that lasted for millennia.

What has been built up in the atmosphere since about 1750 is an increasing load of carbon dioxide gas and other greenhouse gases, which have the effect of throwing an increasingly heated “thermal blanket” over our planet. Now, both the heat conduction pathways and the heat convection currents, described with the use of the model, convey increasing amounts of heat energy over the course of time. As a result the masses of ice at the poles are steadily being eroded by melting despite their continuing of cycles of partial re-freezing during winter, and additional melting during summer.

Simple mathematical models can help focus the mind on the fundamental processes driving complex multi-entangled physical realities. From there, one can begin assembling more detailed well-organized quantitative descriptions of those realities, and then using those higher-order models to inform decisions regarding actions to be taken in response to those realities, if responses are necessary. This point of departure from physics plunges you into the world of psychology, sociology, economics, politics, and too often sheer madness. I leave it to another occasion to comment outside my field of expertise about all that.

Notes on the Technical Details

The cylindrically symmetric equilibrium temperature distribution for a static ocean of uniform depth, which entirely covers a spherical planet, was solved from Laplace’s equation. The temperature of the seafloor everywhere is 4°C, the surface waters at the Equator are at 30°C, and the surface waters at the poles are at -2°C. The variation of surface water temperature with respect to polar angle (latitude) is in a cosine squared distribution. Displays of the 3D surface T(r,ɵ) show isotherms down through the ocean depths at all polar angles (ɵ). The contour lines on the stream function associated with T(r,ɵ) are heat flow streamlines, the paths of the heat gradient (which are always perpendicular to the isotherms).

Bernoulli’s Theorem was applied to surface flow from the equator to the poles (no radial, nor cross-longitudinal motion) for incompressible liquid water with thermal pressure given by:

P(T°C)=[62.25kg/m-sec^2]*exp{0.0683*[T(R,ɵ)-Tp]}

for R equal to the planetary radius to the ocean surface; Tp=-2°C; and using thermodynamic data for water between 32°F (0°C) and 100°F (37.8°C) that indicates a thermal pressure equal to 62.25kg/m-sec^2 in liquid water at 0°C; and that the density of water is essentially constant at 1000kg/m^3 (for the purposes of this model) within the temperature range of the data surveyed.

Inserting P(T°C) into the Bernoulli Theorem definition of equator-to-pole lateral (cross-latitudinal) velocity gives a formula for that velocity as a function of polar angle:

v(ɵ)=±sqrt{(2*[62.25kg/m-sec^2]/[1000kg/m^3])*exp[0.0683*(Te-Tp)]*[1-exp(-0.0683*[Te-T(R,ɵ)])]}

v(ɵ)=±(1.0523m/s)*sqrt{1-exp(-0.0683*[Te-T(R,ɵ)])}

for Te=30°C, and ± for northward (in the Northern Hemisphere) or southward (in the Southern Hemisphere) surface flows.

Global Warming and Ocean Acidification Accelerate

The global warming of the biosphere and its consequent acidification of the oceans is a complex of geophysical, biological and ecological, and sociological phenomena that are all accelerating. There is much that humanity could do to slow that acceleration, and to enact strategies for its own protection from Nature’s escalating assaults on civilization by the grand feedback loop of anthropogenic global warming climate change, but there is really nothing humanity can do to stop it.

Carbon Dioxide Emissions

The anthropogenic emission of carbon dioxide (CO2) — the exhaust fume of economic activity — has increased steadily over the last 270 years, and explosively so for the last 70 years.

Those emissions were 5.28 billion metric tons of CO2 (1 metric ton = 1 tonne = 1000kg = 2,205 lb) in 1950, and 36.15 billion tonnes in 2017 (1 billion tonnes = 1 giga-tonne = 1 Gt). A rough quantitative characterization (analytical fit) to the historical trend of anthropogenic CO2 emissions since the early 20th century is

E = 35.5•[(YEAR-1890)/130]^2, in Gt/year.

The cumulative emissions up to 2017 were 1,540Gt of CO2 (=1.54 trillion tonnes).

Carbon Dioxide in the Oceans

Of the annual CO2 emissions, about 30% are absorbed by the oceans. [1]

A rough quantitative characterization to the historical trend of CO2 absorption by the oceans is

W = 10.4•[(YEAR-1890)/130]^2, in Gt/year.

The cumulative load of anthropogenic CO2 absorbed by the oceans is 450Gt. [2]

According to [3] there are 39,000Gt of carbon currently in the oceans. Since CO2 molecules are 3.667x more massive (‘heavier’) than pure carbon atoms, this represents 143,000Gt of absorbed CO2. The cumulative mass of Earth’s oceans is 1.366GGt (=1.366•10^9 Gt). Thus, the currently absorbed CO2 is in a mass ratio to seawater of 104.7ppmm (=104.7 parts per million by mass). The “ancient” seas (without the 450Gt anthropogenic load of CO2) had 104.4ppmm of CO2.

This seemingly small addition to the CO2 in the oceans has had profound biological and ecological effects, because of the increase of oceanic acidity by 26%. [1], [4] The chemical indicator of acidity used by scientists, pH, has dropped from 8.2 for “ancient” seawater, to 8.1 for present seawater. The pH scale is logarithmic, and its numbers decrease as the solution in question becomes more acidic.

Ocean acidity impedes the ability of shell-forming marine life to produce their protective coverings. With increased ocean acidity, even the shell structures in existence are eroded. These effects make it more difficult for shell-forming marine life to survive, and as many of these life-forms are small (part of the plankton) they are essential foods at the base of the marine food chain. So the ultimate concern about escalating oceanic acidity is the potential for a collapse of marine life. One estimate of the CO2 concentration needed for “ocean death” by acidification is 400ppmm to 500ppmm. [3]

This implies that 400,000Gt to 540,000Gt more of CO2 would have to be deposited into the oceans; a task that would require 38,000 years to 52,000 years of anthropogenic emissions at the current rate (10.4Gt/year into the oceans). However, “ocean dying” is plainly evident with the current quantity of absorbed CO2, and it will only get worse at an accelerating pace as more CO2 is emitted by civilization.

The chemistry of ocean acidification is as follows. [1]

CO2 + H2O + CO3 —> 2HCO3

Carbon dioxide plus water plus a carbonate ion react to form 2 bicarbonate ions. This process occurs in three steps:

CO2 + H2O —> H2CO3

Carbon dioxide plus water form carbonic acid, which is a weakly bound molecule.

H2CO3 —> H(+) + HCO3(-)

Carbonic acid breaks up into a hydrogen ion and a bicarbonate ion.

H(+) + CO3(2-) —> HCO3(-)

The hydrogen ions liberated in the previous reaction find carbonate ions floating in seawater, and combine into bicarbonate ions. The net result is two bicarbonate ions in the seawater solution.

Shell-forming marine life capture carbonate ions, CO3(2-), to combine them with calcium into calcium carbonate, CaCO3, to form their pearls and seashells. Extracting the needed carbonate by breaking apart bicarbonate ions, instead of just collecting free-floating carbonate ions, is more energy intensive and thus a frustration of the shell-forming biology of so much marine life. So, ocean acidification by CO2 removes some of the stores of a formally available free-floating carbonate ions from the reach of shell-forming marine life.

That acidity, a function of the liberated hydrogen ions, H(+), can also dissolve existing shells. [5]

CaCO3 + 2H(+) —> Ca(2+) + CO2 + H2O

Calcium carbonate (shells) plus hydrogen ions react, dissolving the shell, into free-floating calcium ions plus absorbed carbon dioxide gas plus water.

The Rate of Global Warming is Accelerating

From what has been described up to this point, in conjunction with my previous modeling, I calculate the following tabulated results.

Note that the rate at which global temperature is increasing is accelerating, as is the rate of global warming (the Watts absorbed by the biosphere each year). Also note that entries after 2020 are necessarily projections, and are based on the assumption of existing trends (and the analytical formulas fitted to them) continuing. The entries listed for the year 2020 are pointed out to show that earlier entries are backed by data, and later entries are projections; and to note that rate of global warming for any year listed is shown as a ratio to its rate for year 2020.

The Rate of Ocean Acidification is Accelerating

From what has been described up to this point, I calculate the following tabulated results.

As in the first table, entries up to year 2020 are backed by data, while those after year 2020 are projections. Today’s oceans are 26% more acidic than the oceans of the late 19th century. An alternative comparison is that the oceans of the late 19th century were only 79% as acidic as they are today. If the current trend — of annually increasing anthropogenic CO2 emissions — continues to the end of the 21st century, then the oceans would be 144% (2.44x) more acidic than in the late 19th century; or, equivalently, almost twice as acidic as they are today. Those future acidic oceans at pH=7.8 would reproduce conditions during the middle Miocene, 14 to 17 million years ago, when the Earth was several degrees warmer and a major extinction event was occurring. [1], [4]

“Fixing” Global Warming

I see no possibility of a technical “miracle” to fix global warming; something like an anti-global-warming planetary vaccine, making civilization safe to continue with capitalism.

The CO2 in the biosphere is an extremely dilute mass within enormous masses and expanses of air and water. Removing the anthropogenic excesses of CO2 from the air and the oceans would require the filtration of an immense bulk of matter. Processes of such filtration would require immense quantities of energy, to pump and chemically “strain.” Even if we were able to generate sufficient quantities of energy to power such processes, I cannot imagine that generation to be free of CO2 emissions that would exceed whatever quantity of CO2 was strained out of the biosphere. So, I see such ideas of “technical fixes” as fantasies of the perpetual motion machine variety, and obviated by the 2nd Law of Thermodynamics (specifically, as it applies to reversing the process of diffusion).

The only lever I see humanity having with which to influence the pace of global warming is the degree of its restraint in emitting CO2 in the first place. There is no more energy-efficient counter-warming strategy we can devise. The most effective protective armor that can be devised to shield people from the potential harm that playing Russian Roulette can inflict is to not shoot themselves in the head in the first place.

The energy that we do generate and use to counteract the negative effects of global warming (not just to humans, but to thousands of other species) is best spent in transforming our societies and civilization for maximal mutual assistance and solidarity, and minimal competitive tribalism. Some of that energy would go into physical constructions to shield people from floods, inundation, excessive heat and drought; and some of that energy would go into civic arrangements for sheltering, feeding, healthcare and economic stability of all individuals, and the resettlement of those displaced by loss of habitat: by the loss of coastal land to the rising of sea level, and the loss of living space in continental interiors because of the onset of unlivable heat and loss of water.

Essential to the energy efficiency of both devising and implementing such counter-warming social transformations, it is necessary to stop wasting energy on activities without intrinsic social benefits. Specifically, we, worldwide — but most especially among the 10% wealthiest of Earth’s people, who produce 49% of anthropogenic CO2 emissions [6] — need to abandon every trace of profligate CO2-spewing lifestyles enabled by competitive and exclusionary capitalism and its plethora of bigotries, to instead join cooperatively in World Socialism without consumerist economics nor tribal animosities.

Planet Earth is the loveliest jewel we know of in the entire Universe. If we treated it as such, and each other as part of the sparkle of that gem, we would experience lives in an actual Paradise, regardless of how challenging global warming made our existence.

One Year of Global Warming Reports by MG,Jr

Over the last year, I have posted a series of reports on global warming climate change that address it in a quantitative physics, rather than qualitative and sociological manner. Those reports are listed below in chronological order. My estimation of what global warming “will look like” in the immediate and longer term future was refined over the course of producing these reports; but they are all of-a-piece on the topic.

The first report is primarily “data” for subsequent calculations (and very important). The two PDF reports are my mathematical physics notes on my calculations (the first of these being most significant). The other five are applications of the numerical results for descriptive purposes — to help the general reader understand the magnitude and duration of the global warming effect.

A number of these reports found their way onto Internet Magazines, most significantly Counterpunch, and Green Social Thought.

The versions on my blog have had minor numerical and/or typographical errors corrected (as I find them), and are followed by my comments of subsequent thoughts, with more physics on them just after they were posted.

My sociological recommendations about “what to do about climate change” are summarized in one brief paragraph at the end of Biosphere Warming in Numbers.

My purpose in doing this work should be obvious; first, for me to understand, quantitatively, the nature of global warming; and, secondly, to help “you” to understand it.

I welcome comments and questions on the topic; after all it was such inquiries that prompted me to look into this topic (scientifically) more deeply in the first place.

Please also note, I do NOT dispute the work of professional geophysics/climate change scientists, who work at climate change institutes of various kinds around the world (e.g., meteorological, geological, atmospheric physics and chemistry, oceanographic, biological/ecological/evolutionary sciences), and who use banks of supercomputers to model the many complexities of global warming and climate change (with numerous such complexities still beyond current science’s grasp).

Ocean Heat, From the Tropics to the Poles

Carbon Dioxide Uptake by Vegetation After Emissions Shutoff “Now”

If all carbon dioxide emissions were immediately and permanently shut off in the year 2020 (with 417ppm of CO2 presently in the atmosphere), when would the natural uptake of CO2 by Earth’s vegetation (primarily, at first) bring the CO2 concentration down to its “ancient” level of 280ppm?; and when would the average global surface temperature return to its 1910 level (the “ancient” level, with 0°C of global warming)?

By a series of inferences based on my previous calculations of global warming, I estimate that the answers to the above questions are:

1,354 years to reach 280ppm (after an abrupt CO2 shutoff in 2020);

even so, the global temperature will rise another +2.75°C by 300 years (year 2320), remain there for a century (till year 2420), then slowly reduce to the point of 0°C of global warming (the temperature in 1910, used as my baseline for “ancient” pre-warming conditions) in the year 3374.

Figure 1, below, summarizes these findings.

FIGURE 1: CO2ppm/100 and Relative Temperature after 2020 shutoff

What follows is an explanation of how I arrived at these conclusions. It is an exercise of inductive reasoning that I present in a detailed manner for the benefit of the reader’s understanding of my logic, and to give the reader every opportunity to challenge the arguments I advance.

I proceed by making inferences from incomplete data at my disposal, linked as necessary by physical assumptions that are clearly stated, to eventually arrive at projected histories of CO2 concentration in the atmosphere, and the relative temperature (with respect to that of 1910), for the 1,354 years between 2020 and 3374.

Data on Earth’s Biomass

Humanity today comprises only 0.01% of all life on Planet Earth, but over the course of human history our species has destroyed 83% of wild mammal species. [1]

The world’s 7.6 billion people [in May 2018] represent just 0.01% of all living things. Yet since the dawn of civilization, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds. The new work cited is the first comprehensive estimate of the weight of every class of living creature and overturns some long-held assumptions. Bacteria are indeed a major life form – 13% of everything – but plants overshadow everything, representing 82% of all living matter. All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world’s biomass. Farmed poultry today makes up 70% of all birds on the planet, with just 30% being wild. The picture is even more stark for mammals – 60% of all mammals on Earth are livestock, mostly cattle and pigs, 36% are human and just 4% are wild animals. Where is all that life to be found?: 86% on land, 1% in the oceans, and 13% as deep subsurface bacteria. [2]

I assume that “today” 7.7 billion humans are 0.01% of Earth’s biomass, and that the “average” human weighs 65 kilograms (kg), which is equivalent to 143.4 pounds (lb).

From this, the mass of humanity is estimated to be 5.0×10^11 kg, and the totality of biomass is estimated to be 5.0×10^15 kg.

The estimated totality of biomass can also be stated as 5,000 giga-metric-tons. A metric ton (tonne) is equivalent to 1,000 kg.

The following table lists the quantitative estimates made from the data (above) regarding the Earth’s biomass (the NOTES column in the table indicate assumptions made). Yes, there are gaps and imperfections in the table, which reflect the incomplete knowledge I begin with.

Mass of CO2 in the Atmosphere

The mass of Earth’s atmosphere is 5.2×10^18 kg.

To a good approximation, Earth’s atmosphere is made up of diatomic nitrogen (N2), at 79%, and diatomic oxygen (O2) at 21%. The molecular weight of an N2 molecule is 28 (atomic mass units); and the molecular weight of an O2 molecule is 32 (atomic mass units). A conceptual “air” molecule is defined as having a molecular weight that is 79% that of N2 plus 21% that of O2; that value is 28.8 atomic mass units (AMU).

A carbon dioxide molecule has a molecular weight of 44 atomic mass units (the carbon atom contributes 12 AMU, the two oxygen atoms contribute 32 AMU, combined). So, a CO2 molecule is 1.526x heavier than an “air” molecule.

The concentration of CO2 in the “ancient” atmosphere was 280ppmv (parts per million by volume). The mass (weight) of that ancient (original or baseline) quantity of atmospheric CO2 is thus:

(280ppmv) x (5.2×10^18 kg) x (1.525) = 2.22×10^15 kg.

The mass (weight) of the CO2 presently in the atmosphere (417ppmv) is estimated by a simple ratio:

(417ppm/280ppm) x 2.22×10^15 kg = 3.31×10^15 kg.

The difference between the masses of CO2 today, and in the “ancient” (pre 1910) atmosphere, is the “excess” CO2 driving global warming. The quantity is:

(3.31×10^15 kg) – (2.22×10^15 kg) = 1.09×10^15 kg.

That is 1,090 giga-tonnes.

A second route to estimating the mass of CO2 in the atmosphere is as follows.

Modeling of the huge CO2 spike that occurred 55.5 million years ago and that produced the Paleocene-Eocene Thermal Maximum (PETM) was described in [2], drawing on work cited in [3] and [4].

5,000 billion tonnes of carbon were quickly injected into the model atmosphere, producing a concentration of 2,500ppmv of CO2. The modeling showed the excess CO2 being cleared from the atmosphere by a variety of processes, down to a level of about 280ppmv by 200,000 years.

I interpreted the statements about this modeling, in both [3] and [4], to mean that 5,000 billion metric tonnes of carbon (which happened to be bound in carbon dioxide molecules) — but not 5,000 gigatons carbon dioxide — were injected into the model atmosphere.

The ratio of the molecular weight of carbon dioxide, to the atomic weight of carbon is 44/12 = 3.667.

The quantity of injected CO2 (2,500ppmv) in that model is then:

(3.667) x (5,000×10^9 tonnes) x (1,000 kg/tonne) = 1.834×10^16 kg.

By simple ratios I estimate the masses of CO2 at both 280ppmv and 417ppmv:

(280ppmv/2500ppmv) x (1.834×10^16 kg) = 2.05×10^15 kg,

(417ppmv/2500ppmv) x (1.834×10^16 kg) = 3.06×10^15 kg.

Note that by the first method of estimating these masses I arrived at:

2.22×10^15 kg, at 280ppmv,

3.31×10^15 kg, at 417ppmv.

The agreement between the two methods is heartening. So, continue.

Notice that the mass of CO2 per ppm is:

1.834×10^16kg/2500ppm = 7.34×10^12kg/ppm; equivalently 7.34giga-tonne/ppm.

Lifetime of CO2 in the Atmosphere

The modeling of the PETM described in [2], [3] and [4] showed that after about 10,000 years after the “quick” CO2 injection, the concentration had been reduced to about 30% of its peak level, so to about 750ppm.

This means that the mass of atmospheric CO2 was reduced by 12,840 giga-tonnes (from 18,340 giga-tonnes to 5,500 giga-tonnes) over the course of 10,000 years.

Assuming that this reduction occurred at a uniform rate (linearly) implies that the rate was -1.284 giga-tonne/year, or -1.284×10^12 kg/yr.

The Earth during the PETM (55.5 million years ago) and the Eocene (between 56 and 35 million years ago) was ice-free. The Arctic was a swamp with ferns, Redwood trees and crocodiles; and the Antarctic was a tropical jungle. The quantity of vegetation over the surface of the Earth must certainly have been at a maximum.

Roughly half of the CO2 injected into the model of the PETM atmosphere (mentioned earlier) was drawn out by a combination of photosynthesis, uptake by the oceans, and some dissolution of seafloor sediments (chalk deposits), by 1,000 years. About 30% remained at 10,000 years, and that was further reduced (to about 280ppm, or 11% of the 2,500ppm peak) by 200,000 years by the processes of weathering of carbonate rocks, and then silicate rocks.

If the linear reduction rate of -1.284 giga-tonnes/year (estimated for the first 10,000 years of CO2 reduction during the PETM) were operative for the next millennia or two, the excess 1,090 giga-tonnes of CO2 presently in the atmosphere could be cleared down to 280ppm within:

(1,090 giga-tonnes)/(1.284 giga-tonne/year) = 849 years.

However, since 13 million years ago Antarctica has been in a deep deep freeze; and the Arctic has also been a region of deep cold, ice, and minimal vegetation. Also, “since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants.” [1]

So this combination of natural and anthropogenic reductions of Earth’s vegetation from it’s peak during the Eocene would mean that the process of extracting CO2 from the atmosphere by photosynthesis will be slower. For the moment, I assume at half the rate given earlier, or -0.642 giga-tonnes/year. At that rate, clearing the current CO2 excess (linearly) would take 1,698 years.

In [5] I described my model of how average global surface temperature can be influenced by the exponential decay of CO2 in the atmosphere, after an abrupt and permanent cessation of CO2 emissions. I call the time constant (parameter) used in the exponential function that models the longevity of CO2 in the atmosphere, it’s “lifetime.” In [5], I showed a number of post-shutoff temperature histories, each characterized by a specific value of the lifetime parameter, which in mathematical jargon is called the “e-folding time.” The exponential function is reduced to 36.79% of its peak value when the elapsed time is equal to the e-folding time (e^-1).

The case of the e-folding time being 10,000 years (in my model) has the excess CO2 cleared out of the atmosphere by 1,300 years after the abrupt shutoff of emissions (when global warming is at +1°C, as it is now). That “10,000 year case” is shown in Figure 3 of reference [5], and will be described further below.

It also happens that 10,000 years was found to be the time span required to reduce the CO2 concentration in the model PETM atmosphere to about 30% to 40% of its beginning peak value.

So, I infer that 10,000 years is a reasonable estimate of the lifetime parameter (e-folding time) for CO2 in the atmosphere, and that the present excess of CO2 in the atmosphere (417ppm – 280ppm = 137ppm) would be cleared — if there were an immediate and permanent cessation of emissions — within about 1,300 years, which is similar (in this speculative modeling) to the 1,698 years clearing time gotten by halving an estimated clearing rate during the PETM, above.

A linear rate of decrease of 137ppm over 1,300 years would be -0.11ppm/year (this number will be further refined below).

Reduction of excess CO2 concentration after Abrupt Shutoff
(given a 10,000 year e-folding parameter)

Using the “10,000 year case” post-shutoff temperature change history, just noted [5], the following is observed:

The global temperature relative to “now” (2020, at +1°C) is:

above +2.75°C, at 300 to 400 years (net >3.75°C),
above +2.4°C, at 212 to 550 years (net >3.4°C),
above +1.6°C, at 110 to 766 years (net >2.6°C),
above +1.0°C, at 55 to 900 years (net >2°C),
above +0.5°C, at 30 to 1,100 years (net >1.5°C),
above +0°C, at 0 to 1,100 years (net >1°C).

200 years after the temperature overshoot dips below +0°C (below the 1°C of global warming above “ancient” we have now), further cooling returns the global temperature to its level in 1910 (“ancient,” as used here). This is the behavior, over a span of 1,300 years, of the “10,000 year case” calculated in reference [5].

So, I assume that a CO2 “lifetime” of 10,000 years (e-folding time parameter) would result in a reduction of the atmospheric concentration of CO2 from 417ppm (“now”) to 280ppm (“ancient”) in about 1,300 years. That would be a 32.8% reduction of concentration down to a level of 67.2% of the present peak; a linear rate of decrease of 137ppm/1,300years = 0.105ppm/yr (this number will be further refined, below).

Earlier (above) I had found that the mass of CO2 per ppm is:

7.34×10^12kg/ppm, equivalently 7.34giga-tonne/ppm.

If so, then the weight of CO2 removed per year (at -0.105ppm/yr) is:

7.71×10^11kg/yr, equivalently 0.771 giga-tonnes/yr.

The present excess of CO2 is 1,090 giga-tonnes. Clearing it in 1,300 years would imply a uniform (linear) removal rate of 0.839 giga-tonnes/yr.

I will average the two estimates just given for the CO2 removal rate, to settle on:

0.805 giga-tonnes/yr = 8.05×10^11kg/yr

as the CO2 removal rate.

Earlier (above) I found the mass of the present excess of CO2 in the atmosphere to be 1,090 giga-tonnes. It would take 1,354 years to clear away that excess, given a uniform removal rate of 0.805 giga-tonnes/yr.

That reduction of 137ppm over 1,354 years implies a uniform rate of -0.1012ppm/yr.

Earlier (above) I found the total mass of Earth’s plants to be 4,100 giga-tonnes, equivalently 4.10×10^15 kg. The present excess of atmospheric CO2 (1,090 giga-tonnes) is equivalent to 26.6% of the present cumulative mass of all of Earth’s vegetation (plants). The uptake per year is equivalent to 0.0196% of the current total mass of Earth’s plants.

CO2 uptake occurs within the continuing carbon cycle of:

– carbon dioxide absorbed by plant photosynthesis,

– plants consumed as food by animals (heterotrophs),

– organic solids and wastes absorbed by the soil (decay, nutrients, peat, oil, coal),

– carbon dioxide absorbed by the oceans and used to make shells and corals,

– organic gases emitted to the atmosphere (like methane, CH4, which is soon oxidized to CO2 and water vapor),

– re-release of plant-bound carbon to the atmosphere by wildfires,

– mineralization of CO2 by the weathering of carbonate, and then silicate rocks

From “final” quantities and rates determined in all the above, the following projected histories of the reduction of CO2 concentration (in ppm), and global warming (average global temperature excursion above its level in 1910), after an abrupt cessation of CO2 emissions “now,” are determined and tabulated. This is my estimation of the 1,464 year global warming blip projected to occur between 1910 and 3374.

 

Figure 1, at the top of this report, is a graph of this table.

It is important to note that the conclusions of inductive reasoning — as is the case with this exercise — are viewed as supplying some evidence for the truth of the conclusion. They are not definitive as is the case with proofs by deductive reasoning.

In other words, I did the best I could with what I have. Only the unrolling of the future can supply us the definitive answers.

Biosphere Warming in Numbers

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>

Biosphere Warming in Numbers

At this time, the Biosphere is warming at a rate of 3.03×10^15 Watts, which is equivalent to a temperature rate-of-rise of 0.0167°C/year. The warming rate has been increasing steadily since the 19th century, when it was on average “zero” except for natural fluctuations (plus and minus) that were hundreds of times smaller than today’s warming rate.

The total energy use by the United States in 2019 was 100 quadrillion BTU (British Thermal Units), which is equivalent to 1.055×10^20 Joules. Averaged out over the 31,557,600 seconds in a year implies a use rate of 3.34×10^12 Watts during 2019.

From the above two observations, we can deduce that the current rate of Biosphere warming on a yearly basis is equivalent to the yearly energy use in 2019 of 907 United States of Americas.

The total increase in the heat energy of the Biosphere since 1910 is 5.725×10^24 Joules, with a corresponding increase of its temperature by 1°C. That heat energy increase over the last 110 years is equivalent to 54,260 years of U.S. energy use at its 2019 amount, per year.

So, today the Biosphere is warming at a rate equivalent to it absorbing the total energy used by the U.S. in 2019, every 9 hours and 40 minutes.

In 2008, I estimated the energy of a large hurricane to be 6.944×10^17Joules. [1] Thus, 152 such hurricanes amount to the same total energy as that used by the U.S. during 2019.

The heat energy increase of the Biosphere during 2019 was 9.56×10^22 Joules, with a corresponding temperature increase of 0.0167°C. That heat energy increase is the energetic equivalent of 137,741 hurricanes. Now, of course, that Biosphere heat increase during 2019 did not all go into making hurricanes, but it should be easy enough to see that a small fraction (for a whopping amount) went into intensifying the weather and producing more and stronger hurricanes (and consequent flooding).

Two clear observations from all this are:

– the Biosphere is warming at an astounding rate, even if “we don’t notice it” because we gauge it by the annual change in average global surface temperature (which is in hundredths of degrees °C per year);

– the immense amount of heat added to the Biosphere every year is increasingly intensifying every aspect of weather and climate, and consequently driving profound changes to all of Earth’s environments.

Those environmental changes directly affect habitability, and species viability, because they are occurring at a rate orders of magnitude faster than the speed at which biological evolution can respond to environmental pressures.

What should we do about it all?

That is obvious: ditch capitalism and socio-economic inequities worldwide; ditch all forms of bigotry, intolerance, racism, war and social negativity; form a unified planetary political administration for the management of a socialist Earth; deploy reasonable technical mitigation strategies (like drastic reductions in the use of fossil fuels, transforming the transportation infrastructure); implement very deep and comprehensive social adaptation behaviors (“lifestyle changes,” eliminating consumerism, scrupulously protecting biodiversity, resettlement of populations displaced by permanent inundation or uninhabitable drought and heat, worldwide sharing of food production).

None of this will actually stop global warming, as the amount of carbon dioxide already in the atmosphere (assuming it has a lifetime there of thousands of years [2]) has us programmed to warm by about another 1°C to 2°C within two centuries, even if we immediately and permanently shut off all our greenhouse gas emissions.

But, such an improved civilization would experience the least amount of suffering — which would be equitably distributed — from the consequences of advancing global warming; and it would contribute minimally toward exacerbating future global warming.

Long Term Worries Are A Luxury

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>

Long Term Worries Are A Luxury

It is impossible to think about long term problems when you are in the midst of an emergency. Who can worry about the balance of their bank account, or who should get elected, or global warming, when they are in the middle of a medical emergency, or a police nightmare, or a flood, or just the “normal” worries of a homeless person looking for food for themselves or their children, and a safe place to get some badly needed sleep? And this situation is repeated by the billions around the world.

Because so many people are struggling to deal with their basic survival and personal security needs, which are under assault from so many directions by the forces of human malevolence: political, economic and racial, they have no mental capacity nor psychological reserves left to expend on long term worries like global warming. That long term worry is a luxury enjoyed by people who are fortunate in life, secure and safe, and even prosperous. They are also likely to be the kind of people who are in the most anthropogenic greenhouse gas emitting classes on Earth.

I consider global warming to be an emergency, exactly as Greta Thunberg has so brilliantly broadcast to the world. Many professional “Green” activists, bloggers, book writers and internet “influencers” have advanced a variety of social behavioral adaptation schemes, and technical schemes, that governments are urged to mandate and manage in order to “transition” our current profits-above-life-itself economies to a “post carbon” alternative energy mode. In general I agree with such ideas, but I realize they are just fantasies of luxurious long term worries (LLTWs). I suppose my Marxist friends would call LLTWs a class interest.

It has finally dawned on me that the route to real action on global warming climate change is through a complete social revolution that meets the immediate survival and security needs of the great mass of humanity, and which spectrum of aspirations is being vibrantly voiced through the worldwide George Floyd protests. A psychologist might phrase this as the need for a climb up the ladder of Maslow’s hierarchy of needs. The smaller the fraction of the world’s population that is overwhelmingly taxed by scrambling for their survival and safety needs, the larger the fraction of the world’s population that can begin to enjoy the LLTW of global warming climate change.

Because meeting those many aspirations for societal renewal and social transformation are technically the easiest and quickest remedies to begin addressing the root causes of the LLTW of global warming, they should be pushed for hard by everybody who gives a damn. Thus, the George Floyd protests are really for much more than just their essential and vitally important calls for anti-racist anti-capitalist and public health actions by governments, they are also the trumpet fanfares and bugle calls for a worldwide charge up the hierarchy of popular needs, from physical survival and personal security through societal reconstruction based on indiscriminate human dignity and the wide availability of opportunity that affords achievement of personal fulfillment, and ultimately up to us “all” having the luxury to worry about global warming, and then actually act on it.

I do not think there will ever be useful action on global warming until the social needs of the masses of humanity are vigorously and effectively attended to. This is not a utopian fantasy, this is realistic hard nuts logical thinking. The first and foundation step for everything that should follow is for all of us to actually become “we.”

So, yes, I realize that implies many wished-for political, economic and social revolutions and changes, but there it is. That is what “we” need to do if we want to make “anthropogenic” a positive adjective describing our stewardship of Planet Earth, instead of leaving it with its currently negative connotation regarding our massive fouling of the most beautiful jewel known to exist in the entire Universe.

Global Warming and Cooling After CO2 Shutoff at +1.5°C

I have done further analytical modeling of global warming, using the same general method described earlier (https://manuelgarciajr.files.wordpress.com/2020/05/global-warming-model.pdf).

The question addressed now is: what is the trend of temperature change after an abrupt shutoff of all CO2 emissions just as the net temperature rise (relative to year 1910) reaches +1.5°C, given the lifetime of CO2 in the atmosphere?

For this problem, it is assumed that when the temperature rise (relative to 1910) reaches ~+1.5°C, that:

– all greenhouse gas emissions cease;

– pollution grit (which scatters light) falls out of the atmosphere “instantly” (a few weeks);

– CO2 (greenhouse gas) concentration decays exponentially after emissions shutoff;

– for CO2 lifetimes [e^-1] in years: 20, 50, 100, 238.436, 500, 1,000, 10,000, 100,000;

– temperature sensitivities of cloud cover, ice cover and albedo are as in the previous model;

– all other fixed physical parameters are as in the previous model,
(https://manuelgarciajr.com/2020/06/13/living-with-global-warming/).

In general, for the 8 cases calculated, the temperature increases at a diminishing rate after the emissions shutoff, reaches a peak, then trends downward.

The longer the lifetime of carbon dioxide in the atmosphere, the later and higher is the temperature peak, and the longer it takes to cool back down to the baseline temperature of 1910, which is 1.5°C below the starting temperature for this problem.

The 4 figures below show the calculated results.


Figure 1: °C change vs. years after shutoff, for lifetimes: 20, 50, 100, 238.436 years.


Figure 2: °C change vs. years after shutoff, for lifetimes: 20, 50, 100, 238.436, 500, 1,000 years.


Figure 3: °C change vs. years after shutoff, for lifetimes: 238.436, 500, 1,000, 10,000 years.


Figure 4: °C change vs. years after shutoff, for lifetimes: 1,000, 10,000, 100,000 years.

It is evident from the figures that if the lifetime of carbon dioxide in the atmosphere is greater than 500 years, that a temperature overshoot above +2.0°C (relative to 1910) will occur before cooling begins.

If the lifetime of carbon dioxide in the atmosphere is greater than about 250 years, it will take over a century for the eventual cooling to reduce average global temperature to its baseline temperature (which is for 1910 in this model).

If the lifetime of carbon dioxide in the atmosphere is greater than 10,000 years, the temperature overshoot will take global warming past +4.0°C (above our 1910 datum) for hundreds to thousands of years, and cooling back down to the temperature at our datum would take millennia.

The clearing of carbon dioxide from the atmosphere is a slow process. The absorption of CO2 by the oceans, and the subsequent dissolution of seafloor sediments (acidifying the oceans) occur over decades to centuries. The uptake of carbon dioxide by weathering reactions in carbonate and silicate soils and rocks occurs over millennia to many tens of millennia.

It took about 200,000 years to clear away the CO2 that caused the +8°C to +12°C global warming spike that occurred 55.5 million years ago, which is known as the Paleocene-Eocene Thermal Maximum (PETM).

Beyond its intrinsic scientific interest, this study confirms what has long been known as the needed remedy: anthropogenic emissions of greenhouse gases must permanently cease as soon as possible in order to limit the ultimate extent and duration of unhealthy global warming.

My notes on the mathematical solution of this problem are available through the following link

Global Warming, CO2 Shutoff

<><><><><><><>

Climate System Response Time

The parameter “beta” is a reaction rate, or frequency, or inverse response time of the biosphere and its climate system. By my calculation, that rate is 1.329×10^-10 seconds^-1, or 0.004194 years^-1, or a response time of 238.436 years. Of course I am not saying the precision of this estimate is as suggested by all the decimal places shown, it’s just that these are the numbers that come out of my calculations, and these numbers are kept to remind me of what choices I made to eventually arrive at this result.

The parameter beta is the product:

beta = (S•a1)/C = [S•(a-cloud – a-ice)]/C,

where:

S = the insolation on the entire disc area of the Earth (1.7751×10^17 Watts),

a-cloud = the temperature sensitivity of the albedo because of the extent of cloud cover (1/°C),
for a positive quantity of: increase of albedo for a given temperature rise (5.715×10^-3 1/°C),

a-ice = the temperature sensitivity of the albedo because of the extent of ice cover (1/°C),
for a negative quantity of: decrease of albedo for a given temperature rise (1.429×10^-3 1/°C),

C = the heat capacity of the biosphere (5.725×10^24 Joules/°C).

A better determination of a-cloud and a-ice would improve the estimate of beta. I chose these quantities to be in the ratio of 4:1, as is the ratio between the cloud reflection portion of the albedo (24%) to the Earth surface portion of the albedo (6%) for the total pristine (pollution free, pre-global warming) albedo (30%).

So, beta incorporates physical parameters that characterize: solar energy, atmospheric and Earth surface reflectivity of light, and the thermodynamics of the mass of the biosphere.

Events and inputs to that Earth climate system are recognized and responded to on a timescale of 1/beta. Events and inputs with timescales less than 1/beta are blips whose impact will become evident much later, if they are of sufficient magnitude and force. Events and inputs of timescales longer than 1/beta are “current events” to the biosphere’s thermodynamic “consciousness,” and act on the climate system as it reciprocally acts on them over the course of the input activity.

Turning a large ship around takes advanced planning and much space because it’s large inertia tends to keep it on its original heading despite new changes to the angle of its rudder. Even more-so, changes in the direction of Earth’s climate, which may be sought with new anthropogenic rudder angel changes — like drastic reductions of greenhouse gas emissions — will require fairly deep time because of the immense thermodynamic inertia of that planetary system.

This means that the climate system today is responding to the “short time” impulses it was given over the previous two centuries or more; and that both the more enlightened and most stupid impulses that we give it today could take several human lifetimes to realize their full response. We are dealing with Immensity here, and our best approach would be one of respect and commitment.
