Turbo Encabulator Direct Air Capture of CO2

So far, I have resisted invoking the Turbo Encabulator when writing about Climate Change, because I wanted to simplify the argument being advanced in favor of decarbonizing civilization. But, perhaps that was a mistake, and I should have had more faith in the public being able to appreciate a technically focused presentation.

I realize now that it is essential for the public to know that Direct Air Capture of Carbon Dioxide by Turbo Encabulator Extractive Gaseous Reemulsificative Processing by Catalytic Diplexification is THE ONLY method of decycling the accumulated atmospheric carbon dioxide and methane and nitrous oxides, as well as the engorged oceanic plastic waste and bioaccumulative microparticulate inclusions of the biodiverse infundibuluum.

I will begin drafting a brief forty-one page extract for anticipatory publication in the immediate distant future. Be on the lookout for that.

A Simple Explanation of Black Holes

A Simple Explanation of Black Holes

Louis N. Proyect:

I was trying to follow a one-hour lecture on Black Holes [podcast] but gave up after fifteen minutes and switched to Jay Leno’s garage to hear what he had to say about the 1955 Packard Caribbean.

Manuel García, Jr.:

Hawking’s “A Brief History of Time” is a pretty good book about it, for the general public.

Theoretically, Black Holes are a consequence of Einstein’s General Relativity (the effect of gravity on space-time): with enough concentrated mass, and insufficient thermal-nuclear energy generation (a star uses up its “fuel”) to keep that mass puffed out, its mutual gravity draws it into a spherical center, and since mass-gravity “curves” space-time (an effect that diminishes with radial distance from the center) and since space-time curvature is expressed/observed as the bending of light rays; at a particular radial distance (the Schwarzschild Radius) light rays are curved completely by 360 degrees – into circles.

Light emitted and/or passing by a Black Hole outside the SR is bent (by quite a bit but less than 360 degrees close to the SR, and less so with increasing distance from the SR). Light emitted at distances less than the SR are infinitely bent (curly cues), and never travel beyond the SR – they are trapped. Hence “Black Holes” because no light is emitted from them.

Black Holes can be detected by measuring how light rays from a known distance source are bent on passing (outside the SR) near a Black Hole. When Quantum Mechanics is added to the theoretical description of Black Holes, then more odd possibilities arise having to do with matter popping into and out of existence in the vicinity of the SR, but somehow entangled with mirror quantum interactions inside the Black Hole, and from that Hawking proposed ways for gaining information from inside a Black Hole despite the barrier to (non quantum)) information flow, by the SR.

Hawking also presented a theory that such “quantum flickering” (my term, here) could lead to Black Holes steadily ‘evaporating’ into non-existence; analogous to a soap bubble popping. Hawking’s way of describing it for the public is, naturally, very good; but the math behind it all is massively complicated and above my pay grade.

Louis N. Proyect:

I can’t wrap my head around space-time. When I go to the CVS across the street, it takes about 3 minutes. How can a Manhattan avenue and the time it takes to cross it occupy the same continuum?

Manuel García, Jr.:

Think of it this way, first in 2 space dimensions: imagine a checkerboard of grid lines for length and width, and their intersections “define” points in space, or locations. Maritime navigation uses this idea, where the 2D surface happens to be the surface of a sphere (latitude, longitude).

Now, at any single location (say, your desert island) time proceeds forward from a past to a future (you are always in a “now” that is the experienced part of this ‘perpetual’ stream). So now we imagine our checkerboard having vertical “time lines” piercing the horizontal spatial (2D) plane at each “location.”

Hence, the complete description of the 3D space-time of every location is defined by its x and y coordinates (spatial coordinates, like latitude and longitude) PLUS a time coordinate, t, noting the ‘time” point of whatever event is being denoted for location x-y (e.g., your 70th birthday on your desert island).

George Pal’s 1960 movie of H.G.Wells’ “The Time Machine” presented a beautiful description and use of this concept: the Time Machine could go into the past or the future but always fixed to one spot on Earth.

Now, given our actual (or perceived) 3D spatial world, we then exist in a 4D space-time. It is just impossible to draw a visual image of a 4D grid in the 3D space we experience, or on our 2D papers and art pads. But mathematics can describe 4D with exactitude (as multi-dimensional geometry, and with tensor mathematics).

Now for curvature. If you use a checkerboard quilt as a bedspread (to lay out an x-y grid of straight lines (called a Euclidian Space or Euclidian Geometry) and then place a bowling ball in the middle of it, the quilt will be deformed by the weight of the ball (gravity) and the grid lines near the ball will appear curved — because the originally flat surface they were defined in has been warped out of its original “2D-ness.”

That warping of the originally flat surface has a funnel shape: no warping (which is “down”) far away, and increasing warping as one gets closer to the bowling ball. If you now imagine a 2D (spatial) Black Hole, the funneling becomes increasingly vertical (“plunging”) on approach to the SR until it becomes perfectly vertical at the SR.

So, as light rays are in fact the grid lines forced to remain on the spatial surface, however it is warped, then the grid line at the infinite bottom of the funnel (which occurs at the SR) is a perfect circle, and can never “climb out.”

So now, for 3D space it is impossible to draw gravity-induced warping of space-time (which is 4D: 3 space dimensions, 1 time dimension), but the idea is exactly as described above.

To add more fun to it all, by Einstein’s General Relativity, the curving of light rays is equivalent to a slowing of them (analogous to taking your sports into a curve after racing down the Mulsanne Straight). So, with infinite curvature (the situation at the SR) time becomes infinite: or “stops.” Light rays at or below the SR are in “suspended animation” or “eternity,” they are stuck forever.

Lots of science fiction is based on the idea of the “light cones” centered on the “time axis” piercing our spatial here-and-now, coming to our specific (x,y,z,t) out of the past (“history”), narrowing down from the totality of events of the distant past to the single moment-spot of our specific here-now (x,y,z,t); and projecting into the future with an expanding range of possibilities as one projects into the more distant future.

It is easy enough to find images (sketch representations, cartoons, videos) on the internet of this light-cone limitation of the possible causes of this here-now, and its range of possible future effects.

BTW, the “grid lines” in “surfaces” (forming the coordinate system that maps them out) are called geodesics.

Have fun.

Thanks to Louis N. Proyect for asking good questions, and being patient enough to let the explanation unroll.

Light Cones

Why Not Nuclear Power?

I am asked in an e-mail:

“I’m assuming that in 30 or 40 years, everyone will (pretty much) be using nuclear power for their energy needs. By last count, there were 440+ nuclear reactors in the world, with dozens more planned for installation. France (of all countries) is roughly 70% nuclear. My question: Why are people still pretending that nuclear energy isn’t the cleanest, most efficient method available?

My answer: Because it’s not.

The first answer I devised, in 2012, to this question was (“solar power at 1% conversion efficiency on 2% of the land area of the United States of America would produce the total electrical energy use of the nation, 4 trillion kilowatt-hours per year (4T kWh/y)”):

https://manuelgarciajr.com/2015/06/08/energy-for-society-in-balance-with-nature/

My next answer (“nuclear weapons are obsolete”) was to the collateral question about nuclear weapons (which collateral question comes out of the “proliferation” issue associated with civilian nuclear reactors. I presumed the e-mail correspondent’s original question was prompted by my remarks on nuclear weapons posted on CounterPunch on February 1st, https://www.counterpunch.org/2021/02/01/why-it-is-the-way-it-is/)(appended below) was:

https://manuelgarciajr.com/2017/08/09/nuclear-weapons-are-obsolete/

The two factors that would argue against nuclear power are responsibility and efficiency:

1. The “responsibility factor,” (MONEY).

Nobody wants to be the person/entity legally-financially responsible for insuring the nuclear power companies and reactor operators. The cost of “nuclear power malpractice insurance” is literally infinite.

So, governments that do have nuclear power must become (pass laws making) themselves the responsible parties of last resort — which means the public gets stuck with the bills and physical and health risks from all sorts of possible “accidents”: meltdowns and wide area contamination (like Chernobyl and Fukushima), waste storage (nuclear waste gets thermally hot, and if clumped too close or not cooled can explode, as in Russia in 1957) and guarding (from diversion by terrorists) forever (hundreds of thousands of years).

2. The “efficiency factor,” (the 2nd Law of Thermodynamics).

All the work (human and mechanical; intellectual-engineering and physical-construction) that would be required to build up a nuclear power infrastructure (like for mining uranium and refining the ore to reactor grade; and building power plants and waste disposal methods and sites), plus all the related security services needed (to ensure the refining plants don’t take the process to “bomb grade,” and then divert that into nuclear weapons, or it gets stolen!) ‘in perpetuity’ can be quantified as a total energy (or power flow into) needed to create and maintain the nuclear power industry/infrastructure (including its administration and finance agencies).

Does the energy extracted FROM nuclear power…

…(over the lifetime of its plants, whose remnants must be ‘disposed’ of as radioactive and toxic waste; so also over the time required to maintain and guard the disposal sites)…

…EXCEED the energy investment INTO nuclear power, to make that “engine for powering civilization” socially useful? This is called EROEI: energy return on energy invested.

EROEI is used by the oil industry to determine if any well/oil field is worth being pumped. If the energy needed to work the pumping is MORE than the potential energy that can be generated from the oil that could be extracted, then it makes no sense to pump it out. Instead, just use that original energy investment directly into other technical means to produce the work desired for social and economic purposes.

Another reason that re-insurers (the big big money like Credit Suisse that insures insurance companies) mark their costs for nuclear power at INFINITY (kind of like an inversion of Pascal’s Wager) is because they calculate that investments elsewhere (for energy generation) are more profitable (i.e., efficient).

Governments like the USG maintain nuclear power for military reactors, as on aircraft carriers and missile-carrying submarines, because these weapons systems are the technological infrastructure of their imperialism, their global-reach political power (and dick enhancements of the egomaniacal bigwigs in charge) to extract economic advantages (both real and imaginary) from the rest of the world (and entirely for Big Capital, which underwrites and profits from the Military-Industrial Complex: the MIC).

But this is neither energetically nor financially efficient; it is a definite national cost (a pure loss for the public) which is borne by civil society as a degradation of their standards-of-living (the combination of their political freedoms degraded because of “secrecy” and “security,” availability of social services, economic/job opportunities and thus income, and health and safety as it is impacted by the whole nuclear materials/weapons/power complex; guns versus butter).

After the 1979 Three Mile Island meltdown, I wrote this poem:

Which would you rather live in?
A country of 200 nuclear plants, or
A country of 100 million solar collectors?
Which would you rather live in
After the air raids?

If the total current investment into nuclear materials/power/weapons, for all kinds of investments and from all sources, were channeled instead into “green energy” (the technology) and “eco-socialism” (the society powered by that technology), we would all live much much better and more securely and all at much less cost (which cost reduction would include much more effective action to counter climate change).

The great psychological barrier here is the usual one of people of all kinds being resistant to alter their behaviors and adapt to new thinking and technology because they are afraid of losing their personal advantages (money, wealth, jobs, “importance”), their social and economic status (in prejudicial hierarchical societies), and of “losing out” by relinquishing the old ways of “getting ahead,” because of sociological and technical advances (as John Henry, the “Steel-Driving Man,” was resistant, https://youtu.be/oEKAwslJ-_M). This is like the warped and economically unnecessary motivation that keeps Icelandic and Japanese whalers going on today in an activity that is a pure degradation of our interconnected natural world.

And that is why nuclear power continues: because of the mental inertia of those who “can’t” change their ways of life (of ‘taking advantage’ and ‘getting ahead’ of the rest of the world), and which dummies include the vast swathes of Joe Sixpacks and Karens and Jamie Portfolios and Nancy Fashionistas, who just want the continuity of their illusions of “good deals” on guns and granite countertops and big plasma-screen TVs and low-fat de-caff lattes, without any thought about the pesky “weather.”

For all such people, “nuclear energy as the cleanest most efficient method of powering our good life” is confidently held as an obvious truth.

All forms of power (physical and electrical utility power) are statements about the kinds of societies that are envisioned — by their controlling ‘visionaries’ (sic) — as being necessary.

So, the fundamental question is actually: what kind of society do we want? And from that the kind of power technologies that should be mounted can then be most clearly defined and invested in and built and used.

Why It Is The Way It Is
28 January 2021

Here are my reactions to three articles in the 28 January 2021 edition of Counter Punch.

Why We Can’t Give Up on the Idea of a World Free From Nuclear Weapons
https://www.counterpunch.org/2021/01/28/why-we-cant-give-up-on-the-idea-of-a-world-free-from-nuclear-weapons/

The “inability” to relinquish nuclear weapons is entirely a function of the “inability” of power elites to pry their cold dead hands off the levers of power. This is in every way like the “inability” of gun nuts (euphemistically: 2nd Amendment Patriots) to relinquish their guns and military gear costumes; the acting out of a dick measuring contest by deeply insecure people unable to let go of the security blankets they hide behind and which project their illusions of confidence, manhood (and/or penis envy), power and enviable popular acclaim and fear. This is no different from Achilles dragging Hector’s body behind his chariot before the walls of Troy to safely chest-thump his hubristic pride in himself and to inspire terror.

Another, secondary aspect of this clutching onto the obsolescence of nuclear weapons is pure pork-barrel and corporate welfare. It has nothing to do with the logical pursuit of war aims under any conditions. But the disturbing element here is the possibility of an illogical actor — a pure irrational — somehow gaining control of some nation’s nuclear weapons infrastructure Doomsday Machine, as many feared a nutty American president (take your pick) might have done.

I would say that the ideal and polar opposite alternative to the continuation of the Nuclear War Club Delusion is a combination of: the outlawing of war with a robust International Criminal Court with full world participation as championed by Ben Ferencz (https://youtu.be/meDbZemxuK4), with an equally robust worldwide participation in a concerted effort to respond to climate change as urged with fervent and penetrating clarity by Greta Thunberg, and to which I have made my own individual (and I’ll admit amateur) efforts to flesh out with policy visions (as in my last CP article, https://www.counterpunch.org/2021/01/28/from-fractiousness-to-sustainability-is-it-possible/).

While America Was Sleeping
https://www.counterpunch.org/2021/01/28/while-america-was-sleeping/

Alfred W. McCoy describes how the United States has steadily slipped from its long-standing position of world leadership (from 1945 to 2017), both politically but most crucially economically, and which decay of American imperial power and world respect for it is most hideously reflected by the previous four years of the Boobus Americanus Administration.

The increasing economic isolation of the United States from world markets, with Europe, Asia and Africa being steadily drawn into market conformity with China, and effectively assisted by Boobus Americanus’s inept “America First” isolationism, leads me to think that the centroid for the production of carbon-dioxide planetary poisoning has moved to China, with this relocation of World Capitalism’s economic engine.

I am brought back to John Lennon’s thought that the world is run by insane people for insane purposes (https://youtu.be/YspNkm0BKgw). The intellectual refinement and seriousness of the mentalities that carry on the complex and sober work of perpetuating the objectively insane obsession with political domination for exclusionary wealth accumulation — most heinous when self-focussed, but understandably forgivable when aimed at poverty reduction nationally — is breathtaking for its utter disregard to its consequent destruction of our planet. This is “circling the drain-hole” terminal addiction on its grandest scale.

Federal Secrecy Protects the Crimes of Every President
https://www.counterpunch.org/2021/01/28/federal-secrecy-protects-the-crimes-of-every-president/

James Bovard shines a strong light on the putrefaction of American democracy by its envelopment with the hyphae of the “classification” of rightly public information as “state secrets.” Very little of the information generated by government activities needs to be classified either for public safety or the defense of the Constitution (remember, the two official duties and purposes of the USG and its officers) against the attempted hostile actions by ‘enemies’ (who they?) of the American people.

I once had large locking safes filled with blueprints and computer printouts of engineering details of nuclear explosive devices (a.k.a. “bombs”), and I agree those should be classified. But even so, if such blueprints were posted on the internet it might do less for nuclear proliferation than you might imagine. Certainly a few nuclear powers, like North Korea and maybe Pakistan, would be able to improve their own nuclear weapons designs from a study of the U.S. nuclear weapons technology.

But all members of the nuclear weapons club already know how to blend very high level classical physics and engineering with the use of exotic radioactive compounds, gases, metals and salts (the material guts of nuclear bombs) into the construction of functional nuclear explosives. The threat to others from Nuclear War Club members is exponentially amplified when such members also possess high-speed delivery systems with long reach (missiles, submarines and worst of all: satellite platforms).

Most states would never (well, almost never) be able to develop their own nuclear weapons even if they possessed a huge cache of “blueprints” from say the U.S. or Russia or China or England or France or Israel, because they could never mount the huge complex infrastructure necessary to manufacture nuclear explosives, nor accumulate the many exotic materials needed.

But, it is true that any state with civilian nuclear reactors could apply that technology to generate low-grade (and yet super extremely toxic and harmful) nuclear material and waste, which could be used in crude terroristic attacks. So the single best strategy for the prevention of the proliferation of nuclear terror and nuclear weapons is the strict international (U.N.) control of the possession and transport of nuclear materials. Secrecy in the operations of such a nuclear materials policing agency is certainly a public good.

But, as has long been known and which Bovard points out, government secrets in general and the explosion of “classification” by the USG in particular are mostly about embarrassment-control and impunity-perpetuation by and for the lever-pullers in governments.

And it all makes this nerdy très petit bourgeois kid from the Hippy Era, who is irrelevantly far out from the insane consensus on world management, think gratefully of Ben Ferencz, fondly of John Lennon, and wistfully of Greta Thunberg.

SCIENCE

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

SCIENCE awes many, repels many, saves many, is claimed by many, and is practiced by few: because it is hard, hard on the mind, and hard on dishonesty. The poetry of science is in the experience of discovery; the tragedy for science is in its prostitution, pimped for money and power. The promise of science is the dream of humanism: a dream still enslaved by the corruption of men’s souls, the atavistic timorousness of racist fear, of obdurate ignorance. Science is a mode of consciousness, a reflection of a scientist’s attitude toward life, an indicator of the degree of human solidarity. Science is the great unknown to the undiscovered self.

The Artistry of Gifting

In the book The Gift, Lewis Hyde described (among other things) how Bob Dylan benefitted enormously by having copyright-free access to traditional folksongs with which to hone his craft (and gain young artist income for performing them). The production of new art needs the free nourishment of old art in order to continue the cycle of cultural rebirth. http://www.lewishyde.com/publications/the-gift

Bob Dylan just sold his entire catalog of songs (to Universal Music Group) for probably upwards of $300,000,000. Stevie Nicks (of the band Jefferson Airplane, etc.) had previously sold her entire catalog for $100,000,000. Yea Heavy And A Bottle Of Bread, the Summer of Love has withered into the Winter Of Our Discontent: COVID spiking, mass loss of income, mass foreclosures, mass you’re on your own healthcare (mass health don’t care), mass social contamination, exclusive celebrity indemnification.

Tom Lehrer (now 92), the wickedly funny satirist and songwriter, has put his entire music catalog — lyrics and sheet music — in the public domain. He grants everyone permission to do anything they want with his entire artistic/musical output, without cost and in perpetuity. You have till 31 December 2024 to download any or all of Tom’s songs, before he closes his website. https://tomlehrersongs.com/

Who knew in 1959 that “Poisoning Pigeons In The Park” would morph into official U.S. government public health policy (for us homo sapiens pigeons) in 2020? https://youtu.be/yhuMLpdnOjY

Jonas Edward Salk (1918-1995) was a medical researcher who developed the first vaccine against the polio virus. Before the Salk injected vaccine was introduced in 1955, polio was considered one of the most serious public health problems in the world. The 1952 U.S. epidemic, in which 3,145 people died and 21,269 were left with some form of paralysis, was the worst polio outbreak in the nation’s history, and most of its victims were children. According to a 2009 PBS documentary, “Apart from the atomic bomb, America’s greatest fear was polio.” During 1953 and 1954, the average number of polio cases in the U.S. was more than 45,000; by 1962 that number had dropped to 910. https://en.wikipedia.org/wiki/Jonas_Salk

“Salk never patented the vaccine or earned any money from his discovery, preferring it be distributed as widely as possible.” https://www.salk.edu/about/history-of-salk/jonas-salk/

Between 1954 and 1961, Albert Sabin (born Abram Saperstein, 1906-1993), a medical researcher, went through a tremendous effort to develop and test an oral vaccine against all three strains of the polio virus. To develop and prove the safety of Sabin’s oral vaccine, upwards of 100 million people — in the USSR, Eastern Europe, Singapore, Mexico and the Netherlands — were tested with it.

The success of that campaign by 1960 opened the door to testing in the United States, on 180,000 school children in Cincinnati. The mass immunization techniques that Sabin pioneered with his associates effectively eradicated polio in Cincinnati, and that technique along with the oral vaccine itself broke the chain of transmission of the virus, and has led over the last four decades to nearly eradicating the disease worldwide.

“Sabin refused to patent his vaccine, waiving every commercial exploitation by pharmaceutical industries, so that the low price would guarantee a more extensive spread of the treatment. From the development of his vaccine Sabin did not gain a penny, and continued to live on his salary as a professor.” https://en.wikipedia.org/wiki/Albert_Sabin

On 12 April 1922, Frederick Grant Banting (1891-1941), Charles Herbert Best (1899-1978), James Bertram Collip (1892-1965), John James Rickard Macleod (1876-1935), and John Gerald “Gerry” FitzGerald (1882-1940) — the key participants in the project (in Canada) to develop therapeutic insulin, a project initiated by Banting in 1920 — wrote jointly to the president of the University of Toronto to propose assigning the patent for the artificial production of insulin to the Board of Governors of the University in such a way that:

“The patent would not be used for any other purpose than to prevent the taking out of a patent by other persons. When the details of the method of preparation are published anyone would be free to prepare the extract, but no one could secure a profitable monopoly.”

The assignment to the University of Toronto Board of Governors was completed on 15 January 1923, for the token payment of $1.00. Following further concern regarding (drug company) Eli Lilly’s attempts to separately patent parts of the manufacturing process, Robert Defries (Assistant Director and Head of the Insulin Division at Connaught Laboratories, which administered the insulin patent) established a patent pooling policy which would require producers to freely share any improvements to the manufacturing process without compromising affordability. https://en.wikipedia.org/wiki/Insulin#Discovery

“Tell me someone who’s not a parasite, and I’ll go out and say a prayer for him.” — Bob Dylan

Some people are successful in life and lucky, but some are successful at life and are radiant.

Seisetsu, a Zen master in ancient Kamakura, required larger quarters to alleviate the overcrowding of his many students. Umezu Seibei, a well-to-do merchant, decided to donate 500 piecers of gold (called ryo) for that purpose. “All right, I’ll take it,” said Seisetsu. But Umezu was dissatisfied with Seisetsu’s response because a person could live a whole year on 3 ryo, and Umezu had expected an effusive thanks. So he reminded Seisetsu that 500 ryo was a lot of money that he had been donated. “Do you want me to thank you?” asked Seisetsu. “You ought to,” replied Umezu. “Why should I?” asked Seisetsu, “the giver should be thankful.” [see #53 in the book Zen Flesh, Zen Bones, by Paul Reps (1895-1990)].

And that’s it, isn’t it?: you donate because you are grateful that you are able to do so. Gratitude is enlightenment, and that is the artistry of gifting.

The Gift is an excellent book, if you are an artist, or at least appreciate art, read it (try your public library). http://www.lewishyde.com/publications/the-gift

The Climate Threat from Arctic Methane Releases

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

The Climate Threat from Arctic Methane Releases

A friend, who is an intelligent person with no science background, asked me to explain simply what the concern expressed with alarm by many scientists and (anti) climate change activists is about the increasing rate of methane gas emissions in the Arctic. That attempted explanation follows.

From even before the extinction of the dinosaurs by the Chicxulub Meteor 66 million years ago (66mya), to about 34mya, the Earth was much warmer (the peak occurred 50mya) and there was no polar ice, north or south.

Antarctica was covered in forests and jungles; the Arctic Ocean was a warm sea ringed by swamps and forests of ferns and Redwood trees along the Eurasian and North American northern continental shores; and those swamps swarmed with crocodiles.

Between 34mya to 12mya Earth’s temperature fluctuated and Antarctica froze thawed and refroze. Then Panama swung into place closing the oceanic gap between North (Central) and South America, and that altered ocean currents so that a Southern Ocean circumpolar current sealed off Antarctica climatically: the deep freeze of that continent that continues to this day.

That global cooling trend continued after 12mya and plunged Earth into the deep cold of the repeated glaciations of the Pleistocene Epoch (Ice Ages), from 2.58mya to 11,700ya, before the thawing of temperate latitudes introduced the balmy global climate we have enjoyed since.

All the lush and soggy vegetation around the Arctic Ocean was buried by sedimentation into the shallow continental shelves around that ocean, and then further locked away by the deep freeze producing permafrost, which extends quite a bit down below the ground surface, and down from the top of the seafloor of the shallows near land.

Rotting organic matter in the seas (algae, plants, fish, animals) sinks to the bottom and is decomposed by bacteria, and that produces methane gas (like cows fart from eating grass, and we fart from eating beans); but because of the cold and pressure deep down in all oceans, or in cold shallower seas like the Arctic, that gas actually combines with water into a fragile unstable crystal-like solid called methane clathrates or methane hydrates.

This is an “ice” that people can light up with a match and it burns like gas-soaked charcoal, but with a blue flame. When a methane hydrate solid is brought up to the surface of the ocean from the high pressure of the depths, it can spontaneously ignite because of the release of methane gas mixing with the oxygen in the air. Such flares have been seen on the ocean surface at night by airline pilots.

There is a large amount of compressed, frozen methane-rich organic matter, including peat, all along the sub-Arctic ring of sea and land about the Arctic Ocean. The thawing of that region is now increasingly releasing some of the trapped gas: from out of the clathrates, from out of subsurface compressed organic plant matter, and also from new underground fires burning peat seams and coal seams. Such fires are now extensive and burning continuously all along northern Siberia; they are called Zombie Fires.

Because of the complexities of molecular structure, a molecule of methane (CH4) has 2.5x (15/6) more ways of moving, plus rotating about and vibrating along the chemical bonds between its atoms, so as to store heat, than does a molecule of carbon dioxide (CO2). So, CH4 is 2.5x times more effective at being a global warming agent than CO2.

A large release of CH4 into the atmosphere will have a more pronounced global warming effect than an equal mass of CO2. But CH4 eventually combines with atmospheric oxygen molecules to form more CO2 and H2O (water).

What is happening in the Arctic is that the massive amount of stored subsurface methane — in all the forms that bound it — is now being warmed sufficiently to allow it to overcome the cold and pressure that used to hold it in. So there is an increasing rate of methane gas bubbling up from the seafloor, and from the Arctic tundra which is permafrost grassland that is thawing, slumping, and popping out with methane eruption craters, some tens of meters in diameter and depth. [1], [2]

Because of that accelerating rate of emission, and because the total amount of methane stored in the Arctic is so large, climate scientists are very concerned about the negative potential for our climate in the near future.

How worried? How fast? How alarming?

Well, the presently accelerating rate of carbon dioxide buildup in the atmosphere, and of global warming, is proceeding at a pace at least 20x that of previous major CO2 eruptions and global warming events in Earth’s geological past (like during the onset of the Paleocene-Eocene Thermal Maximum, 55.5mya); and that rate today could even be hundreds of times faster.

The CO2 increase in the atmosphere over the last century or so has equaled comparable amounts of increase that may have occurred over several thousand years during the massive eruption episodes in the geologic past that caused major extinctions.

During those past eruption events, where the pace of change was over thousands of years (a blink of the eye geologically), despite the extinctions that occurred much animal and plant life was able to adapt, and such adaptation carried on over longer spans of time was their transformation by biological evolution.

But today such a tactic of biological adaptation by a species in response to the shifting of climates is impossible because the genetic processes of evolution are far outpaced by the rapid rate of increase of CO2 concentration, and thus of global climate change.

However, we are not talking about doomsday in 5 or 10 years. Just think of how climate and weather have changed (gotten worse) since, say, the 1970s, and imagine a similar rate of degradation for another few decades, and you can then guess that sometime near the end of this century (maybe the 2070s) that Earth will really be at the edge of environmental collapse: if humanity had continue to do nothing about curbing its greenhouse gas emissions since this moment, and continues heedlessly emitting fossil fuel exhaust fumes beyond that point. 

Many people worry that such an unhappy timetable could be sped up if there were to be a truly massive eruption of “all” the methane locked up in the Arctic. If I get to live to be 100, in 2050, I’ll then know the ultimate course of Earth’s dynamic climate system.

Young people worldwide, sparked by Greta Thunberg [3], will be alive in 2050 and very much want to know NOW what the environmental conditions will be THEN, when they are supposed to experience their adult lives and be responsible for continuing civilization. And they have every right to demand that today’s adults do their intergenerational duty to pass on a hospitable Earth that sustains their dreams, our human civilization, and all species’s futures.

Within the next 10 years we had better begin to actually and continually cut down civilization’s (anthropogenic) annual CO2 emissions; by 25 years we had better be reducing them at a very pronounced rate; otherwise by 50 years Earth’s temperature may be high enough to trip the climate system into a new mode we will very much dislike — being much more of what we don’t like now — and which will be beyond our ability to correct regardless of whatever heroic measures we would then take, like miraculously dropping our CO2 emissions to zero forever.

The geophysical reality is that it takes the climate system hundreds of years (I once estimated 240 years) to BEGIN to shift in response to new atmospheric conditions. This is like a huge thermostat lag to a heating system of global scale, or like the lag between turning the rudder on a large ship and then actually having the ship begin to veer in a new direction.

It is because of this inertia that it is essential to stop our emissions as soon as possible (ASAP). The longer we wait — emitting more while waiting — the longer it will take Earth to respond to our finally throttling our emissions, and the longer it will take for the climate system to flush out that excess CO2 and lower the average global temperature. I estimate 1,000 to 1,400 years, but it could be much longer.

So that is what the worry about the increasing Arctic methane releases is all about.

The CO2 and Temperature of the PETM

The Paleocene-Eocene Thermal Maximum (PETM) was a 200,000 year long period 55.5 million years ago (55.5mya) at the transition from the Paleocene Epoch to the Eocene Epoch on the geological timescale, of highly elevated global temperature and carbon dioxide concentration in the atmosphere — the highest since the demise of the dinosaurs 66mya.

The average global temperature is estimated to have been +5°C to +8°C higher than it is today, which current average can be taken to be 15°C (59°F). Thus, the average global temperature during the PETM was in the range of 20°C (68°F) to 23°C (73.4°F). [1]

A recent study published by the ETH (in Switzerland) has determined that:

“Accordingly, between 57 and 55 million years ago, the mean annual air temperature at the equator where Colombia lies today was around 41°C (105.8°F). In Arctic Siberia, the average summer temperature was 23°C (73.4°F).” [2]

The cause of this elevated global temperature was a large amount of carbon dioxide (CO2) and methane (CH4) in the atmosphere. How much of each, and how did they get there? There are numerous theories and no definitive answers. My sense of a general scientific consensus is that a large swarm of volcanic eruptions in the North Atlantic volatilized layers of methane hydrates (the cold pressurized crystalized precipitates of organic matter decayed by bacterial action) on the seafloor, as well as spewing CO2; and that wildfires and the burning of peat may have contributed to the carbon emissions.

The PNAS paper presents data supporting the idea that CH4 overwhelmingly dominated the greenhouse gas load, with CO2 concentration remaining steady at ~1000±500 ppm [1]; while the ETH report states that: “At that time, the atmosphere was essentially flooded by the greenhouse gas carbon dioxide, with concentration levels reaching 1,400ppm to 4,000ppm.” (ppm = parts per million) [2]

The amount of carbon lofted into the atmosphere, according to the PNAS paper, was in the range of 2,500GtC to 4,500GtC (GtC = giga metric tons of carbon = gigatonnes C); but it cites alternative scientific studies whose estimates range from 6,800GtC to 15,400GtC. [1] Their methods of analysis were unable to determine the timescale of the emissions pulse, but it must have been well less than the 200,000 year span of the PETM, to account for its recovery back to the “normal” conditions of the early Eocene Epoch.

Methane emitted into the atmosphere will eventually oxidize to CO2 and water by chemical reactions like the following:

CH4 + 2*O2 -> CO2 + 2*H2O

CH4 + 4*O -> CO2 + 2*H2O

CH4 + O3 -> CO2 + H2O + H2.

There are many more possible reactions because there are many intermediate species formed, such as: H (atomic hydrogen), OH (hydroxyl radical), HO2, CO (carbon monoxide), H2O2 (hydrogen peroxide). So it is likely that within a few millennia of a massive CH4 release that it has all been oxidized to CO2 and water vapor.

Thus, I thought it reasonable to model the PETM temperature history as due to an emissions pulse of CO2. Specifically, that pulse is a Gaussian with a full width at half maximum (FWHM) of 4,000 years (4ky); centered at 6ky from the start of the PETM, and with a peak emissions rate of 1,456GtC/ky (1,456 GtC per 1000 years, or 1.456GtC/y). By 12ky from the start of the PETM, that pulse has come and gone leaving 6,190GtC in the model PETM atmosphere.

Figure 1, PETM CO2 pulse (12ky)

The calculated CO2 concentration added rises to 2,500ppm between 9ky and 10.5ky from the start of the PETM, (presumably there was ~280ppm, or more, prior to the emissions pulse).

Figure 2, PETM GtC/ky, GtC, CO2ppm (12.5ky)

This model assumes that the composite relaxation time for CO2 absorption from the atmosphere is 40ky. The dominant process fixing atmospheric CO2 is taken to be the weathering of carbonate and silicate rocks and soils; and the processes of both photosynthesis and the absorption by the surface waters of the oceans — which act on much shorter time scales — are assumed to be saturated because of the high concentrations of CO2 in both the air and the oceans.

The course of this model PETM atmospheric carbon excursion out to 20ky is shown in Figure 3, and out to 100ky is shown in Figure 4.

Figure 3, CO2ppm (20ky)

Figure 4, CO2ppm (100ky)

Beyond 100,000ky, the model PETM CO2 concentration falls into the range of the pre-industrial levels of ~200ppm to ~300ppm.

The model atmosphere at 0ky was taken to have 0ppm of CO2, so everything shown in the Figures is only added carbon (added CO2). The added heating caused by the added CO2 is estimated at:

+∆T °C = [CO2ppm added]/[130ppm/1°C] – 11°C,

where a baseline has been assumed of an average global temperature of 11°C at “0ppm” (actually 170ppm to 270ppm) as existed in the depths of the Ice Ages of the Pleistocene Epoch (2.58mya to 11.7kya), when the global temperature hovered about -4°C±4°C from what it was in pre-industrial times (~15°C).

The ratio 130ppm/1°C comes from my estimate of a +130ppm rise in atmospheric CO2 (280ppm to 410ppm) during the 130 years between 1890 and 2020, accompanied by an average global temperature rise of 1°C.

The calculated history of the model PETM average global temperature rise — by the above method — peaks at +8.2°C, between 9.3ky and 10ky, and is shown in Figure 5. Thus, the peak average global temperature implied was 19.2°C (66.6°F).

Figure 5, +T°C from PETM carbon pulse

If I assume that the model PETM temperature rise calculated above actually rested on a background global temperature of 15°C, similar to pre-industrial conditions (which might seem inconsistent, but there are many uncertainties), then the peak of the model PETM global temperature is 23.2°C (73.8°F).

Note that the ETH results were: +26°C at the Equator (41°C = 105.8°F) and +8°C in the Arctic during summer (23°C = 73.4°F), which are hotter for middle and tropical latitudes than in the model here.

My study here cannot rival the scientific rigor of [1] and [2] and it cannot quantify the entire complex of climate-affecting phenomena that occurred during the PETM; but it does give a clear general picture of a hyperthermal excursion caused by a massive pulse of carbon emissions into the atmosphere as occurred during the PETM.

The climate at that time was hotter and wetter, and with no polar ice; Antarctica was jungles, and the Arctic was a crocodile-infested swamp-ringed ocean.

Another Model of Atmospheric CO2 Accumulation

I continue to model the accumulation of carbon dioxide (CO2) in the atmosphere, because the topic fascinates me.

This time, I constructed a global warming scenario driven by a pulse of anthropogenic CO2 emissions (mathematically, a slightly skewed Gaussian function), which launches in the year 1900, peaks in the year 2028, and disappears by year 2150. This model emissions rate function matches the actual trend of the increase of anthropogenic CO2 emissions (data) since the year 2000.

The point of this study is to see how a reduction of anthropogenic emissions, as by the mathematical function assumed, would influence the subsequent reduction of CO2 accumulation in the atmosphere.

The equation describing the accumulation of carbon dioxide in the atmosphere is based on these assumptions:

– 70% of the emissions accumulate in the atmosphere,

– 30% of the emissions are immediately absorbed by the oceans (surface waters),

– the only sink (mainly photosynthesis) is characterized by a relaxation time of 238 years (a characteristic time scale for the absorption process),

– emissions peak in ~2028 at 11.5GtC/y (42.1GtCO2/y) and die away skew-symmetrically thereafter. (GtC/y = giga metric tons of carbon per year; GtCO2/y = giga metric tons of carbon dioxide per year).

Figure 1 shows the resulting projected temporal profile of atmospheric CO2, in units of ppm (parts per million). Also shown is the emissions function, E(x), scaled by 50x GtC/y. The unperturbed baseline concentration is assigned as 277ppm.

The time scale, “x” in years, begins (x=0) at year 1900.

Figure 1: Time Profile of Atmospheric CO2 Concentration, for given Gaussian emissions pulse

In this scenario, the CO2 concentration peaks at 529ppm for years 180<x<200 (years 2080-2100). The continuation of this story out to year x=1200 (year 3100) is shown in Figure 2.

Figure 2: Time Profile of Atmospheric CO2 Concentration, to year 3100

Choosing a longer relaxation time (e.g., ~1000y) would significantly reduce, or eliminate, the decay of the concentration over time (the air CO2 would “never” go away). A long relaxation time would be the case if weathering were the dominant absorption phenomenon (with relaxation time ~12,000 to ~14,000 years), because the photosynthesis and absorption by the oceans sinks were saturated (as was the case during the 200,000 year-long clearing of atmospheric CO2 during the Paleocene-Eocene Thermal Maximum, PETM, 55.5 million years ago).

Figure 3 shows the increase in global temperature, in °C, corresponding to the CO2 concentration profile, shown above.

Figure 3: Average Global Temperature Increase corresponding to model CO2 concentration profile

The global temperature increase above baseline, for this scenario, is projected to peak at +1.94°C in year x=190 (2090); it arrives at +1.5°C at x=142 (year 2042).

It is obvious that if the future reality of anthropogenic CO2 emissions is an increasing trend, that the consequent time profile of atmospheric CO2 concentration will be a continuously rising trend as well. That would mean higher global temperature increases, and sooner, than those shown here.

The Gaussian emissions pulse used here is an “optimistic” scenario in that the annual rate of anthropogenic emissions peaks in 8 years, and then decreases nearly symmetrically to its profile of increase prior to 2028.

This scenario would have us avoid crossing the +2°C threshold. But, the global warming would remain above +1.5°C for the 130 years between 2042 and 2172, undoubtedly degrading many environments.

The model CO2 concentration profile found here matched data (measurements by NOAA); quite well since 2000, and adequately before that to 1960.

The important implication of this model is already well-known: if we begin reducing anthropogenic CO2 emissions very soon, and continue doing so at a steady rate so as to eliminate them completely within a century, we can avoid having Planet Earth warm up by a total of +2°C, relative to the 19th century.

The corollary to this observation is that if we instead continue increasing our CO2 emissions, it will get warmer sooner for longer.

Also, whatever we do (or don’t do) about CO2 emissions, their accumulation in the atmosphere will linger for centuries. The clearing of this atmospheric CO2 will occur on several parallel timescales:

– absorption through photosynthesis (happening daily),

– capture by the surface waters of the oceans over the course of years, decades and centuries (and eventual sequestration at the sea bottom in a surface-to-bottom mixing cycle of millennial time scale), and

– the chemical reactions of rock weathering (on a tens-of-millennia time scale).

Injecting CO2 into the atmosphere can be done instantly; removing it requires a long time.

So, it would be wise to stop emitting it.

The above report, with the addition of figures showing comparisons to data for the trends of emission rate and CO2 concentration prior to 2020, is available here (PDF file).

Reducing CO2 Emissions to Reverse Global Warming

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

Reducing CO2 Emissions to Reverse Global Warming

We know that Global Warming can be reduced during the years of the century ahead of us if we — our civilization — steadily reduces its emissions of carbon dioxide gas (CO2) into the atmosphere.

Given a specific rate for the reduction of anthropogenic (our CO2) emissions:

— how long will it take to return Earth’s average temperature to its unperturbed pre-industrial level?, and

— how much higher will Global Warming (Earth’s temperature) become before it begins to decrease?

Answering these questions is the subject of my recent study. This work is based on a Carbon Balance Model, which I described in an earlier report. [1]

That model has been further refined in order to address these questions, and the details of that refinement are described in a technical report. [2]

Prior to the buildup of anthropogenic CO2 emissions in the air, the fluxes of CO2 released by the respiration of Life-on-Earth; and the fluxes of CO2 absorbed from the air by photosynthesis, the surface waters of the oceans, and rock weathering chemical reactions; were in balance. That balance is known as the Carbon Cycle.

As the rate and buildup of anthropogenic emissions increased (after ~1750, but particularly from the mid-20th century), the Carbon Cycle was perturbed out of balance, and the magnitude of that imbalance is determined by the difference between two effects: Anthropogenic Sources, and Stimulated Sinks.

The Anthropogenic Sources are:

— the CO2 emissions by the human activities of fossil-fueled energy generation and industry, and

— the CO2 emissions from land use changes (deforestation and its attendant increase of wildfires).

The Stimulated Sinks are the additional absorption of CO2 by photosynthesis and the surface waters of the oceans, because of higher atmospheric concentrations of CO2. At a sufficiently high level of atmospheric CO2 concentration, both these sinks will saturate — stop absorbing CO2. What that “sufficiently high level” is remains uncertain.

The work summarized here includes more realistic (more complicated) models of these source and sink terms in the rate equation for the change of the Carbon Balance over time.

Now I am able to quantitatively link specific rates of the reduction of anthropogenic CO2 emissions, to consequent projected histories of the slowing and then reversal of Global Warming.

Such quantitative linkages have long been featured in the super-computer models of CO2 accumulation in the atmosphere, by the major Climate Science institutes; but now I have my own quantitative version of this correlation, which is analytical (expressed as math formulas, and enumerated with a hand calculator and basic home computer).

Anthropogenic CO2 emissions in year 2020 are 42.2GtCO2/y (42.2 giga-metric-tons of CO2 per year = 42.2*10^+12 kilograms/year). This magnitude of total anthropogenic emissions, E, is the addition of our fossil-fueled and land use emissions.

I considered three cases of the intentional steady reduction of annual human-caused CO2 emissions, which are defined to decrease exponentially. The characteristic decay time of each case is: 40 years (CASE 1, a 2.5% annual reduction), 100 years (CASE 2, a 1% annual reduction), and 200 years (CASE 3, a 0.5% annual reduction).

Emissions would be reduced to half their initial rate in 28 years for CASE 1; in 69 years for CASE 2; and in 139 years for CASE 3.

If each of these reduction plans were alternatively initiated in the year 2020, then:

CASE #1, ∆t=40y:

This trend reaches a peak of 449ppm and +1.32°C in year 2048 (in 28 years); it remains above 440ppm and +1.25°C over the years 2032 to 2064 (between 12 to 44 years from now); then descends to 350ppm and +0.56°C in year 2120 (in 100 years); and 300ppm and +0.18°C in year 2140 (in 120 years).

CASE #2, ∆t=100y:

This trend reaches a peak plateau of 485ppm and +1.6°C over the years 2078 to 2088 (between 58 and 68 years from now); it remains above 480ppm and +1.56°C during years 2066 to 2100 (between 46 and 80 years from now); it descends to 350ppm and +0.56°C in year 2202 (in 182 years); and 300ppm and +0.18°C in year 2225 (in 205 years).

CASE #3, ∆t=200y:

This trend reaches a peak plateau of 524ppm and +1.9°C over the years 2125 to 2135 (between 105 and 115 years from now); it remains above 500ppm and +1.72°C between years 2075 and 2190 (between 55 and 170 years from now); and descends down to 360ppm and +0.64°C in year 2300 (in 280 years).

Message to the Humans

The singular challenge for the progressive political and social elements of our civilization is to awaken the rest of the world — and particularly the “developed” and “developing” high-emissions nations — to a full commitment (demonstrated by action) to steadily and significantly reduce anthropogenic CO2 emissions for the rest of human history.

The sooner such reduction programs are initiated, and the greater the vigor with which they are implemented, the sooner we will begin slowing the advance of Global Warming and its continuing erosion of the habitability of Planet Earth, which humans have enjoyed for over 2 million years, and particularly since the end of the Ice Ages (~11,000 year ago).

With decades to a century of discipline applied to this purpose, we can even reverse Global Warming. The longer we wait to do this, the worse the consequences we will have to suffer through, and the longer it would take to extricate our species — and so many other wonderful forms of Life-on-Earth — from the Hell-on-Earth we are creating by our willful and destructive ignorance.

I can only imagine such major programs of CO2 emissions reductions being synonymous with the economic, political and social uplift of the vast majority of people, because Global Warming is directly caused by the unbounded economic, political and social exploitation of the many by the few.

The fact is that we all live on the same planet, and whatever happens to it — whether worsening conflagration and flooding in the now, or eventual cooling and restoration by human commitment — will affect everybody. There is no guaranteed escape.

The CO2 accumulation model that I have described here is just this old scientist’s way of saying: We can do so much better for ourselves, and our children deserve that we try.

Anthropogenic CO2 Emissions Are Fate

Anthropogenic CO2 Emissions Are Fate

I developed a model of Global Warming based on the anthropogenic perturbation of the Carbon Cycle. The essence of this model is a rate equation for the evolution of the carbon dioxide (CO2) concentration in the atmosphere.

The interesting results from this model are projected trends for the CO2 concentration and the average global temperature during the next century. The character of those trends — whether rapid rises, shallow plateaus, or diminishment into the future — depend crucially on the magnitude of our civilization’s emissions of CO2, and whether those anthropogenic emissions increase or decrease with time. In the real world at present, they are increasing.

I have now been able to include the effect of linearly increasing or decreasing anthropogenic emissions into my Carbon Balance Model, which has been significantly improved.

This model also includes the effect of the increase in the rate at which atmospheric CO2 is absorbed by photosynthesis and the surface waters of the oceans, because those absorption rates are increasingly stimulated by the higher levels of CO2 in the air. This process of absorption-enhancement cannot continue indefinitely as the atmospheric CO2 concentration increases, but at what point of elevated CO2 concentration it saturates and then absorption largely shuts down, is unknown.

The third process included in the model is that of the slow absorption of atmospheric CO2 by the chemical reactions of weathering on the surfaces of rocks and soils. CO2 not “quickly” scavenged from the air by photosynthesis or the surface waters of the oceans will stay airborne for 12,000 to 14,000 years. The ~2,500ppm spike of atmospheric CO2 that occurred 55.5 million years ago took 200,000 years to clear away. That geological episode is known as the Paleocene-Eocene Thermal Maximum (PETM). At that time there was no ice at the poles, instead they were jungles and swamps with crocodiles. The global temperature at the peak of the PETM was as much as +12°C to +18°C warmer than in our pre-industrial 18th century.

I made three case studies from this model, called E-growth, E-flat, and E-fall.

E-growth

The E-growth case is driven by a relentlessly steady rise of anthropogenic CO2 emissions, based on the average upward trend of those emissions between years 1960 and 2020.

This trend arrives at 470ppm of atmospheric CO2, and a warming of +1.5°C (above pre-industrialization), in the year 2038 (in 18 years). It arrives 540ppm and +2°C in year 2055 (in 35 years); and it arrives at 800ppm and +4°C in year 2100 (in 80 years).

E-flat

The E-flat case is driven by a constant annual rate of 42.2GtCO2/y of anthropogenic emissions (42.2 giga-metric-tons of CO2 emissions per year), which is the rate in year 2020.

It arrives at 470ppm and +1.5°C in year 2041 (in 21 years); and 540ppm and +2°C in year 2070 (in 50 years); and 600ppm and +2.5°C in year 2100 (in 80 years).

E-fall

The E-fall case is driven by a steady linear reduction of anthropogenic emissions over 40 years: from 42.2GtCO2/y in 2020, to 0GtCO2/y in 2060; a reduction of 1.05GtCO2 every year for 40 years. This amount of annual reduction is 2.5% of the total anthropogenic emissions in year 2020. In this scenario, after year 2060 we would continue our civilization with zero CO2 emissions from our human activities.

This trend rises to 437ppm and +1.23°C during years 2035 to 2040 (from 15 to 20 years in the future) after which both fall. It arrives back down to 407ppm and +1°C in year 2059 (in 39 years); and 320ppm and +0.4°C in year 2100 (in 80 years).

Finally

In this year of 2020, we are presently at 417ppm and +1.08°C.
