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.

Ophiocordyceps unilateralis fungus

A Scientific American article from 2009 describes the following [1]:

The Ophiocordyceps unilateralis fungus infects Camponotus leonardi ants that live in tropical rainforest trees. Once infected, the spore-possessed ant will climb down from its normal habitat and bite down on a leaf, with what the authors call a “death grip,” and then die.

After the ant death, the fungus begins growing hyphae inside the insect’s body; in a few days, the hyphae would emerge from the exoskeleton—”always … from a specific point at the back of the head,” write the authors of the study, which was led by Sandra Andersen of the Center for Social Evolution at the University of Copenhagen in Denmark. Within a week, the fungus had grown to about twice the length of the host ant’s body and had started sexual reproduction. Meanwhile, “the ant cuticle is … remodeled into a protective case by reinforcing the weaker parts,” and the parts of the fungus inside the ant’s body appear to differentiate into separate functions, write the researchers.

When the fungus releases spores, it creates what the authors describe as “an infectious ‘killing field'” about one square meter below the ant body that could infect C. leonardi ants or similar species that are unlucky enough to walk there.

Much more about the Ophiocordyceps unilateralis fungus is given in [2].

Alcon Blue Butterfly

Caterpillars of the Alcon Blue Butterfly have developed an outer coat that tricks ants into believing the young are their own because it smells like ant grubs, duping the ants into carrying the larvae back to their colonies to feed and care for, even at the expense of their own grubs since the Alcon Blue caterpillars smell like queen ant grubs, so the worker ants feed them preferentially. The Alcon Blue caterpillars grow fat in their ant nests, pupate, and then fly away to reproduce and continue their species’s parasitic life cycle.

Alcon Blue Butterflies are found in Europe and across the Palearctic to Siberia and Mongolia. They occur on damp meadows where Gentiana (Marsh Gentian, a purple 5-petal flower) grows; they are plentiful in such places, sometimes even in abundance, from the end of May into July, but in the North not before the end of June. [3]

SARS-CoV-2

The SARS-CoV-2 coronavirus that was first identified in Wuhan, China, in December 2019, has blindly evolved an ingenious strategy for perpetuating itself — perhaps indefinitely — through its host population: riding on human stupidity, impatience and selfishness.

Were people everywhere to follow the anti-pandemic protocols of:

– maintaining a greater than 2 meter distance from other individuals in public;

– self-quarantining for 2 weeks to ensure they are not infected before entering a new household or social environment since much viral spread is by asymptomatic carriers;

– wearing masks over their mouths and noses to prevent their breath-plumes, sneezes and coughs from spewing possibly infected droplets into the meters of airspace around them;

– thoroughly washing their hands often with soap and water (preferably hot), especially after contact with strange objects or people;

– avoiding gatherings, especially large ones, and especially for lengthy periods;

then the SARS-CoV-2 virus particles would have much greater difficulty finding and infecting hosts, and that virus species would eventually die out because of the decay and rupture of its particles’s outer lipid (fat) casings exposed to atmospheric oxygen and environmental heat.

Following this protocol requires discipline, patience and intelligence, because it is annoying. Our lack of discipline (to so regulate our personal behaviors), patience (to stick with the protocol for the duration of the pathogen species’s lifespan), and intelligence (to recognize the reality we must grapple with rationally, which has been exposed by scientific research), in aggregate is SARS-CoV-2’s winning strategy. It eats us out through our undisciplined emotionalism and our preferential fantasy ideas.

Capitalism

Capitalism — as championed by the United States and the high-carbon-footprint part of the International Community that surrenders all its mental capacity and moral character into the logic-bubble of Free Market speculation and finance — is a fungal idea among homo sapiens that causes them to destroy the environments and biodiversity of Planet Earth in frenzies of mineral extraction, overfishing, forest clearing, wildlife extinctions and soil depletion, so as to monetize these bites out of Nature for immediate short-term gains, while in the process spewing out enormous quantities of carbon dioxide and methane gases into the atmosphere (~12GtC/y, or ~42GtCO2/y, [4]) as the exhaust pollution of their so-called “economy.” All of this is hidden under the phrase “global warming” (“anthropogenic global warming” if you want to be a smarty-pants).

The rate of humanity’s CO2 and methane emissions is increasing annually, and global warming and ocean acidification (killing the marine food chain) are accelerating. If left unchecked, anthropogenic global warming will ultimately warm the planet and sterilize the oceans, so that the climate is too hot, too parched and Earth too food-depleted for our species to continue in its current numbers, and ultimately at all (if still here, we will know the ultimate trajectory of our fate within 2 centuries).

Is capitalism our Ophiocordyceps unilateralis, a mass psychosis causing our species to self-limit or even self-destruct, to open evolutionary space for other species (probably of bacteria) to evolve and explode their populations to dominate Life-On-Earth? Is it all part of Nature’s unfolding — or “God’s Plan” as the ‘intelligent design’ religious cultists would call it — to prod homo sapiens off the stage of Life-On-Earth after its scripted 200,000 year scene?

Why not? It is certainly hard to see humans as entirely self-actualizing rational beings who make logical decisions on the basis of scientifically verified facts, given the obvious zombification of so many of them by the mere presence of SARS-CoV-2 virus particles in the environment, and by the immateriality of the idea of ego-centric capitalist wealth that drives them wild.

Democratic Party

Tracing its heritage back to Thomas Jefferson and James Madison’s Democratic-Republican Party, the modern-day Democratic Party was founded around 1828 by supporters of Andrew Jackson, making it the world’s oldest active political party.

The wikipedia entry for the Democratic Party gives this capsule summary of its history:

Before 1860, the party supported limited government and state sovereignty while opposing a national bank and high tariffs. In the late 19th century, it continued to oppose high tariffs and had bitter internal debates on the gold standard. In the early 20th century, it supported progressive reforms and opposed imperialism. Since Franklin D. Roosevelt and his New Deal coalition in the 1930s, the Democratic Party has promoted a social liberal platform. Well into the 20th century, the party had conservative pro-business and Southern conservative-populist wings; following the New Deal, however, the conservative wing of the party largely withered outside the South. The New Deal coalition of 1932–1964 attracted strong support from voters of recent European extraction — many of whom were Catholics based in the cities. After the Civil Rights Act of 1964 and the Voting Rights Act of 1965, the core bases of the two parties shifted, with the Southern states becoming more reliably Republican in presidential politics and the Northeastern states becoming more reliably Democratic. The once-powerful labor union element became smaller after the 1970s, although the working class remains an important component of the Democratic base. People living in urban areas, women, college graduates, and millennials, as well as sexual, religious, and racial minorities, also tend to support the Democratic Party. [5]

The resentments over the diminished impunity of White Supremacy because of the Civil Rights Movement and Civil Rights legislation in the 1960s, along with the societal trauma of the Vietnam War, and the reactionary backlash to the law-and-order chaos spawned by antiwar sentiment and the massive routine racial discrimination, economic privation and violence against Blacks (e.g., the assassination of Rev. Martin Luther King, Jr. in April of 1968), which sparked major rioting in numerous cities, along with the economic recession of the 1970s, fueled the expansion of a reactionary, or “conservative” mindset that exploded out of the head of the body politic and into full view like an Ophiocordyceps unilateralis hyphae in the person of Ronald Reagan, the U.S. President inaugurated on 20 January 1981.

The neoliberal regime established by Margaret Thatcher in the United Kingdom in 1979, and Ronald Reagan in the United States in 1981, continues to this day: few restraints on corporate capitalist exploitation of the public commons (and human misery), with always diminishing support for human needs, and with economic austerity imposed on the wage-dependent public to pay for the enrichment of the wealthy.

To compete against the Republican Party — the shining knights of neoliberalism — in U.S. electoral jousts, the Democratic Party turned to new young leaders, beginning with Bill Clinton (U.S. President from 1992 to 2000), who led it away from concentrating on the defense and representation of the wage-dependent public and instead to seek corporate funding to underwrite the political campaigns and lush careerism of its leadership elite, who instead devoted themselves to facilitating the capitalist ambitions of their patrons.

So, the Democratic Party became the Republican Party of Dwight D. Eisenhower (U.S. President from 1952 to 1960, when the top income tax rate was 90%), while the Republican Party of Eisenhower hardened into the neofascist party of Ronald Reagan (1980-1988), George H. W. Bush (1988-1992), George W. Bush (2000-2008), and Donald Trump (2016-?).

The continuity of the neoliberal regime in the U.S. since 1980 was maintained by the post-1990 corporatist Democratic Party during its command of the White House during the administrations of Bill Clinton (1992-2000) and Barack Obama (2008-2016). In fairness to the Democrats, they were sometimes a little less rabid about forcing socially and behaviorally oppressive policies on the public (of AIDS-denial, and on: birth control, abortion, pollution and unionization, for example).

But, the electoral successes of the Democratic Party steadily declined — despite their acceptability to (or tolerance by) a wider range of Americans beyond Paled-Faced Capitalists — as they became less distinct from the Republican Party by their adherence in both word and deed to the neoliberal orthodoxy. Barack Obama even cited Ronald Reagan as one of his heroes and role models, instead of pissing on the memory of Reagan’s public evil (e.g., PATCO, Nicaragua, El Salvador, Guatemala, Grenada, South Africa, Iran-Contra) as any truly decent socially-conscious human being would want to do.

So, is the Democratic Party of the last 30 years a political Ophiocordyceps unilateralis fungal agent whose purpose is to zombify the struggling and not-always-alert wage-dependent American public to allow itself to be remorselessly eaten out for the perpetuation of neoliberal capitalism, which is only enjoyed by a select population of privileged societal Alcon Blue Butterflies (until Biosphere Environmental Collapse occurs)?

If the Democratic Party is intent to continue as a reliable electoral failure, despite toadying zealously for the corporatocracy (e.g., Hillary Clinton, Joe Biden, Kamala Harris, Nancy Pelosi, Chuck Schumer, Diane Feinstein), then the very least it could do would be to regain its self-respect and fight vigorously in the defense of the wide spectrum of individuals in the wage-dependent public whom it has long abandoned.

As the reelection yesterday (3 November 2020) of Alexandria Ocasio-Cortez, Ilhan Omar, Rashida Tlaib, and Ayanna Pressley, along with the election of Cori Bush in Missouri clearly shows, the championing of that public and their human needs against the predations of neoliberal capitalism and its attendant racism can have resounding electoral successes, because: “When you stand for nothing, you fall for everything.” [6]

Once an American mind has been seized by the brain-fever of neoliberal economics, why would it vote for its feeble imitation as the Democratic Party when it can get “the real thing” from the Republican Party, with the added bonus of being able to happily liberate repressed bigotries into the expansive shit-hole of Trumpofascism?

Death-Grip by Fungal Ideas

Our climb to escape from geophysical and socio-economic realities to latch onto self-terminating delusions, with both personal and societal death-grips, is caused by the zombification of people, our societies and our species into self-destructive behaviors for the benefit of external parasites, by the action of fungal ideas — mindless and non-material — : our fantastical and selfish ideas about the COVID-19 pandemic, about capitalism and neoliberal economics with its global warming denial, and about acquiescing to the shameless careerism and anti-democratic machinations of the corporatist ideologues of the Democratic Party.

Because those parasitic agents plaguing us can only infect us virtually — through ideas — unlike the actual materiality of the Ophiocordyceps unilateralis fungus and the SARS-CoV-2 virus particles, they can be most easily defeated by simply changing our thinking, which is done without fuss by people of rational mind who are disciplined, patient and intelligent. Unfortunately, not everybody is so constituted, and many people are purely reactive, as stated by Harmless’s Principle: “People don’t change until they feel pain.” [7] But this is not physiologically necessary, to the extent that cognition is free of disease and free-will has scope to operate.

We can act in our own best self-interests in ways that blend into decent life-affirming people-centric societies and political-economic government policies, that in turn mesh harmoniously with the workings of Nature to continue our species indefinitely, with sustainable energy and food production (e.g., Regenerative Agriculture [8]) in collaboration with the continuation of a bounteously biodiverse Life-On-Earth; at least until geophysical or astrophysical forces that are truly beyond human influence (e.g. another Chicxulub Meteor, or the Sun’s expansion into a Red Giant) dictate otherwise.

So I ask that you look upon the old saying “clearing the cobwebs from my mind” with a new more critical and motivated intent.

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.

In his CounterPunch column on 30 October 2020 [1], the editor-publisher, Jeffrey St. Clair, made the following refreshing comment:

“In his resignation letter, Greenwald goes a little far in claiming his story was ‘censored.’ Call it the victim of a strong editorial hand. Cockburn used to apply his frequently to my stories and his normal scalpel was replaced by a ruthless chainsaw whenever my subject matter strayed onto the fraught terrain of climate change, assault weapons or catch-and-release trout fishing.”

I have had the same experience with my articles and papers in every single publication I have submitted them to (even CP). I came to learn that each journal has its ideological boundary, within which is its acceptable orthodoxy, and outside of which is rejected heresy. The arbiter determining the exact contour of that boundary is the editor, and moreso when also the publisher.

This is not necessarily bad if the precepts of the orthodoxy and contour of its boundary line are clearly stated, and uniformly adhered to. Then you as a reader and writer know how to pick and choose what to get into, or not. We all prefer to sing in our own choirs and thus perpetuate a world of mutually repellant cacophonous babel, because it is so much easier to maintain our ignorance and prejudices that way.

Having said this, I have to add in all fairness that CounterPunch has been the most tolerant of any journal toward my submissions (better than 50%). If you want to eliminate all censorship and editorializing on your writings, then just publish them yourself in a blog, or just don’t bother. Believe me, most people don’t want to hear or read what you think, however much your ego would be pleased to think they do.

At this point I thought I would editorialize a bit more on the editorial just cited.

– = MG,Jr.

+ Biden losing Texas because he made little to no effort to secure the Hispanic vote and couldn’t effectively distance himself from Obama’s inglorious record as deporter-in-chief will be one of the most biting ironies of this strange campaign.

+ The Biden campaign has made two shrewd strategic decisions: One, to limit Biden’s own appearances; and two, to keep Bill Clinton off the campaign trail, even though Bubba might have drawn some bigoted white men over to Biden in Georgia and South Carolina.

– Spanish speaking Americans are most likely voting overwhelmingly for Biden anyway as the obviously preferable lesser evil to raging Trumpian Hispanophobia. We (i.e., ‘Hispanics’) always know that U.S. elections are competitions between two corrupt gangs of ‘pasty-faced knuckle-headed palookas’ (a fabulous phrase from the Three Stooges) united by capitalist ideology. We make inroads as we can with young new progressives, like Alexandria Ocasio-Cortez, and with the numerous non-PFKHP activists over the years. Also, in time we will demographically bury PFKHP Trumpphilic America, because we are way better lovers.

+ Usually, the lies get more grandiose the closer we get to an election. This year, however, there’s been a refreshing outbreak of honesty. Biden has pledged that he will “not end fracking.” And Trump’s chief staff Mark Meadows has vowed that Trump “will not control the pandemic.”

– It’s all about the money. It has always been all about the money. This is the United States you’re talking about: “Capitalism is a religion. Banks are churches. Bankers are priests. Wealth is heaven. Poverty is hell. Rich people are saints. Poor people are sinners. Commodities are blessings. Money is God.” — Miguel D. Lewis

– Fracking = fossil fuel = power for U.S. military machines = international political power = profits = careerist orgasms; therefore the Next White (or Whitened) Guy In The White House is 100% for it.

– “Controlling the pandemic” is a tax on “the economy” a.k.a. the exclusive corporate casino subsidized by the public, both by their tax submissions and by their acquiescence to death by incompetence and neglect. Also, laissez-faire as pandemic control is the mentally easiest policy for PFKHPs to manage.

+ The grooming of AOC for a leadership position in the party seems to be well underway. Consider her placid reaction to Biden’s retreat on fracking: “It does not bother me … I have a very strong position on fracking … However, that is my view … It will be a privilege to lobby him should we win the White House, but we need to focus on winning the White House first.”

– Lighten up on AOC. She and Greta Thunberg have done more to wake people up to working for a better U.S. and better world than all the U.S. politicians and pundits of the last 50 years, excepting the activist kids of 2018 from the Marjory Stoneman Douglas High School in Parkland, Florida.

– AOC has made the most startling and effective puncturing of the PFKHP political bubble since god knows when, and has near-instantly built up a political potential so threatening to PFKHP patriarchal control that its flaccid intelligentsia across its entire spectrum for reactionary Trumpofascism to Pelosischumer liberal pablum has been driven into apoplectic frenzies of attack against the future that AOC personifies: young, female, feminist, inclusive, non-PFKHP (and non-‘Karen’), multilingual, socialist, smart, honest, engaging and effective.

– Jacinda Ardern, New Zealand’s newly reelected Labour Prime Minister, is another personification of that advanced political future (a reality in New Zealand, as yet a dream in the U.S.). The fact that AOC is also urban and a Puertorriqueña is icing on the cake (for this Nuyorkino). The great fear in weakling PFKHP minds is demographic dilution, and they see their projected image of that fear as AOC, before whom they tremble: rage as pretense for fear.

+ Who will tell DiFi? McConnell, just after the Senate voted to limit debate on Amy Coney Barrett: “A lot of what we’ve done over the last four years will be undone sooner or later by the next election. They won’t be able to do much about this for a long time to come.”

– Climate change (crisis, emergency, catastrophe) is a universally acknowledged fact, often brutally so in the wake of hurricanes, floods, droughts and wildfires. The culpability of major corporations in fueling global warming by the overproduction and sale of fossil fuels and petroleum products (like plastic by the Coca Cola Company) for the last half century, and of doing their utmost to cover up the scientific findings about the root causes of global warming (that’s where “anthropogenic” comes in) so as to continue maximizing their profits by destroying the environment, are all now public knowledge.

– Therefore, it is inevitable that the public will increasingly point the accusatory finger at the oil companies (for CO2 pollution fueling global warming) and plastic producers (for ocean and biodiversity destruction) in the form of class action lawsuits. The evidence of guilt is overwhelming; there is no exculpatory evidence. The only way that future corporate defendants would be able to secure favorable judgements once they have been harpooned by such lawsuits would be to advance payments now into insurance policies known as campaigns to install as many corporate-friendly judges into the higher echelons of the corporate-friendly U.S. judiciary as possible, and as soon as possible. This is how to buy judges legally in the United States, where “justice” is a commodity.

– And that is what the frenzy to install Amy Coney Barrett into the Supreme Court was all about. Her daddy was an oil exec, so she’s part of the family of the petrocorp ancien régime. Her religious fundamentalism is incidental to the corporatocracy (though it’s a great distraction for the hoi poloi); it’s all about the money.

+ Reporter: “What do you say to Philadelphia residents that are outraged by yet another unarmed Black man being shot by police?”
+ Biden: “What I say is that there is no excuse whatsoever for the looting and the violence.”

– Except by the PFKHP supremacist U.S. military abroad, and occupation troops (a.k.a. ‘police’) domestically. It used to be called “manifest destiny,” now it’s called “exceptionalism.” What the ancien régime fears most is having its own tactics used against it, and its various euphemistic expressions of that fear, as given by Biden here, are its most forthright admissions of guilt.

+ It’s become a fixture of American political culture where those who later apologize for being wrong about a disastrous policy (regardless of the body count) are given more attention and credibility than those who made the right call from the beginning.

– This is because such heartwarming forgiveness is dispensed by the U.S. mass media, which in aggregate is the privatized propaganda ministry that touts disastrous-for-the-public corporate-friendly government policies with alacrity. These are sinners forgiving their own sins, which the public had to become impoverished and bleed and die to underwrite (as in the 2008 financial meltdown, and Vietnam and Iraq Wars).

+ In the last two years, Trump’s Department of Energy has blocked the release of more than 40 reports on renewable energy: “They just go into a black hole.”

– The U.S. Department of Energy is a government agency for the maintenance of U.S. nuclear weapons capability, infrastructure and production. Anything else they may do is auxiliary. While there is much more that the US DOE could do to further renewable energy (I know, I used to work for them through a contractor, and my renewable energy reports just ended up on my blog), that is not a concern of the petrocorp ancien régime that owns the government.

– It may help to remember that John Jay, an author of the Federalist Papers and the first Chief Justice of the U.S. Supreme Court, was fond of saying: “The people who own the country should run it.” By “people” Jay meant wealthy merchants and slave-owners like himself. This is what the Supreme Court has always been about (with the exception of a few deviations by people like William O. Douglas, Thurgood Marshall and surprisingly by Earl Warren): the defense of property against democracy.

+ The Arctic’s giant methane deposits are beginning to leak their climate-wrecking fumes. Adjust your doomsday clock accordingly.

+ A worst-case climate scenario could produce almost $500 trillion in damages—about twice all the wealth in the world today. A best case still inflicts about $30 trillion in damage, a new study in Nature estimates, with intermediate scenarios between $69 trillion and $131 trillion.

+ According to a post-debate Morning Consult poll, only 28% voters oppose transitioning away from the oil industry. 52% of independents support transitioning away, and even 41% of Republicans.

– The exploding magnitude of the problem of global warming is only matched by the degree of reluctance by politically organized human society to reformulate its civilization into balance with Nature, and thus into harmony with the continuation of biodiverse Life-On-Earth. The mental inertia behind our non-action is from the static self-images many people have of themselves (‘I have to keep living and working this way because I can’t imagine otherwise’), and from our near-universal fetishizing of money.

– “The economy” is an artifice that can be constructed any way “we” want — so people could easily be made more important than profits — and money is just a token that is easily printed on government paper, and is now even generated as electrons vibrating in computer memory circuits. It doesn’t matter how much “money” it costs to formulate a decent society in harmony with Nature; money is shit, and shit is fertilizer.

+ Trump’s war on wolves just went nuclear…
+ The decision to remove the protections for gray wolves across all 48 states is going to have lethal consequences in Wisconsin, where the state’s “wolf hunt” will be immediately reopened.

– What it really is, deep down, it is the pleasure of inflicting cruelty on the helpless by terrified weaklings.

+ Ned Norris Jr., Chairman of the Tohono O’odham Nation, on the border wall’s desecration of Indigenous sacred sites: “As Americans, we all should be horrified that the Federal Government has so little respect for our religious and cultural values.”

– It’s all about the money; it is the pleasure of inflicting cruelty on the helpless by terrified weaklings; it is so much easier to maintain ignorance and prejudices that way; it is a reaction to the increasing fear of demographic dilution and the puncturing of the political bubble of PFKHP patriarchal control; it is manifest destiny and exceptionalism; it is the fearful wrath of the American money-constipated ancien régime.

– Capitalism must die for the world to live.

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).

The Connected, and The Unmoored

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

The Connected, and The Unmoored

I saw the sunrise, from pitch black to clear light over the canyon rim this morning. An owl was hooting before the light, the air warming as the dark faded. Heard the birds wake up and each begin its chatter; the hummers buzzing over my head to inspect me before tanking up at the nectar bottle. The turkeys gobbled confidently from across the canyon.

Made French Press coffee. Watched our cats play, stalking and chasing each other on the hill as morning light expanded. We later ate some simple cold cuts, cheeses, bread, pasta salad; cool water.

I played, stumbling with some exponential functions, trying to simulate CO2 buildup in the atmosphere (55.5 million years ago, and also again today), a perennial project. Seems pointless to tell people about it, but it keeps my mind occupied, and I’m curious. That CO2 and its growing heat will be with “us” for centuries, a millennia? (who cares?).

Went out a few times to look at the day, which was lovely, with only a subdued hint of ash haziness from the fires up north. My mother is living with us for a while, waiting it out. She told me of her grandmother who raised her, who was born in the last days of Spanish rule in Puerto Rico, before the 1898 takeover by the Yankee Conquistadores. My mother wishes she could buy the platanos to make pastelón, like her grandmother used to make for her in Río Piedras.

I thought of my father, who would have been 96 on his birthday during these early days of October. I remember the stories he told me of his father’s childhood, spent with his father sheepherding in the Cantabrian Mountains, in the very early years of the 20th century: stories of facing off against prowling wolves, armed with long wooden staffs and Great Pyrenees mountain dogs, of drinking wine from the bota, of wild strawberries, and bagpipes.

Watched a nature video from 26 years ago, about Caribbean sea life, so lovely then. Had Caprese and guacamole (with tortilla chips) for supper, both made to perfection; I handwashed the dishes.

Watched a video (from 30 years ago) on the life and art of Mozart; I always have tears well up when I hear the Lacrimosa.

Life is short, and there is so much to do, so much to experience, even for us lacking the talent, grace and insight of a Wolfgang Amadeus, and I see none of what is worthwhile in the close-in noisy opaque bubbles everyone jams their heads into to plug up their senses with the flickering trivialities and remote dramas of the moment.

The owl, the birds, the turkeys, the cats, the critters who keep out of my sight (but not the cats’s), and later the crickets at night, they all know what is happening at any moment every moment. They have to, to eat, to stay alive; for them paying attention is the essence of living, but so is napping in the sunshine, which they all in their turn do so luxuriantly.

We can be so pitifully disconnected, and most of us always are, for we just don’t notice the whole world changing: drying, melting, burning, receding, dying. It’s no wonder animals look at us with such amazement: “how could they be so clueless?” There’s always a reason I guess, a crisis of the moment, to not get out of your head and wake up to the flow of the world; but that’s just tragic: death. It’s also why people feel so alone, because in fact they are alone in desert bubbles, befuddled, lost castaways, wired to artificiality: empty static.

I realize I’m an anti-social socialist, a hermit socialist, “out of the loop” in every way for sure. And I need to be, it’s best.

My boy black cat — Buster — will bump into my leg at night, when I’m out looking onto the deep sound of the unseen. He understands of course, his connection to the primordial is undimmed by civilization, his wisdom is locked safely in DNA that has been 25 million years in the imprinting, and I appreciate his encouragement.

Burning Thoughts on the Sonoma Fires

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

Burning Thoughts on the Sonoma Fires

The map shows the fires in Sonoma County, California, USA, during 2017-2020. These were/are all big. My mother had to evacuate in 2017, and stayed with us for 10 days. Today (28 September 2020), I went to get her and bring her here again.

I monitor the internet to follow the progress of the fire (the Glass-Shady fire of 2020 – now – is 0% contained; it started about 2 days ago – see the red blotch). This year I know of 8 people – 5 directly and personally – who have had to evacuate from fires: in Sonoma and Solano Counties, and in Oregon. Many fires in Western America right now, and they occur from earlier in the year, and more frequently, and last longer, and are bigger, with each succeeding year.

Other regions and nations have their own increasing environmental degradation trials and tribulations: droughts, heat waves, crop failures, locusts, storms, hurricanes, floods. My thoughts about all this are rather dark, as reflected in my recent writing.

The gems to be found in all these hard events are the generous and kind actions individuals can take on behalf of others, very often strangers, to help them get through the difficulties and losses. I was fortunate to have two such people help my mother (who is 95) in the first rush to evacuate yesterday. The fact that people, as individuals, can be so decent is what keeps me from condemning all of humanity (being a total misanthrope) because human society has been so adamant to continue failing miserably when it comes to seriously addressing global warming climate change.

In this, my attitude is similar to that of Jonathan Swift, who said he cared not for human society, but appreciated John and Tom and Dick (I paraphrase) because of the very thing I just described: stellar individuals (even if just occasionally so) live among a society we curmudgeons find morally bankrupt, and their good actions are momentary redemptions of that reprehensible mass.

This outlook makes it basically impossible for me to find any interest (or waste any time) on the many frivolous concerns of others, and which are often most on display on that frivolity of social media: Facebook. Sorry about that.

My appreciation for the beauty and organic complexity of Nature remains undimmed, but my interest in the minutia of the daily drama, or the silly entertainments of the last 15 minutes (with shelf lives of 10 seconds), is zero. I can’t help looking at American society as reenacting the fate of Captain Ahab and his crew, so obsessed with their delusions that they could not wake up from them even as they were being drowned by them.

The Romantic in me wants the Next Generation to float free from the doom we’ve programmed ourselves for, like Ishmael floating free atop Queequegs’s coffin; and refashion the World aright. The Realist in me is not so optimistic. But I don’t feel it is fair for me to criticize the Next Generation, whose elders – as American Society – have so basely used and poorly provided for. I had a decent shot at life, and did what I did with it; now it’s their turn, and they should be free to make their own choices, and learn (hopefully) from their mistakes (preferably enjoyable ones) just as I and my predecessors did (well, some of us did).

The Romantic Engineer and Artist in me knows that tackling Climate Change – which means entirely transforming human society worldwide – would be the greatest adventure, and moral and social uplift, that our species could ever have in its history as part of Life-On-Earth, if we “all” had the Zen-like satori (awakening, AHA!) to motivate a joyful coming together to achieve that purpose in all of its many dimensions: personal, political, social, economic, technical, moral, intellectual; the fullest expansion of human potential for everyone.

The Realist in me scoffs at this flight of fancy by the Sappy Curmudgeon, but the Romantic in me still wishes it were not entirely a hopeless dream. Others, I know, have particular and detailed wishful fantasies for our Future, and I have few quarrels with most of them. But I think the simplest life of fulfilling work (self-assigned), safety, security, health, happiness and freedom for artistic and intellectual pursuits; with Nature secure in all its beauty – on this Planet! – is my ideal.

My mother is now afraid that she will be threatened by fires every year. This should not be so, she should be able to live tranquilly tending her roses without such concern. That our governments and societies will not do anything — as we should for the rest of human history — to eliminate such fear (which many people now have) has led me to cancel any sense of allegiance to them, or respect for “the institutions.” Like Jonathan Swift.

Conflict and Choice for Human Survival

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

Conflict and Choice for Human Survival

What can you say about people for whom the beauty of Nature does not inspire, and the fear of its destruction does not motivate?

People do not change unless they feel pain. Politics does not allow for social improvements unless first stung by social revolts. The idea of a spontaneous, peaceful and uneventful evolution of social improvement is delusional. Conflicts are necessary before social improvements can arise. The greater the need for those social improvements, the greater the conflicts necessary to open the possibilities for them to be realized.

Such conflicts always involve violence to one degree or another. Realistic proponents of non-violent social agitation know that the minimum violence necessary for them to achieve their goal requires that their people — the non-violent — suffer all the violence generated during their struggle, and which violence is perpetrated by the reactionary elements of society, those opposed to the social improvements sought. The status quo always reacts with violence to maintain itself. In the United States today that status quo is the domination of all aspects of economic, political and social life by White Supremacy and Capitalism. The magnitude of societal violence escalates in a vicious cycle as social reformers increase their own resorts to rebellious violence. Such vicious cycles are civil wars.

So it has been throughout history, and so it seems destined to remain for our species, as long as we are unable — by being unwilling — to renounce such behavior and evolve beyond it.

As of today, it seems that those who aim for the social improvements needed for all of humanity to live through the deterioration of climate brought on by affluent-human-caused global warming, and to eventually reverse it, will have to resort to social conflicts that admit to the inevitability of violence; minimally reactionary violence, and at worst civil wars.

If there is any threat of premature human extinction, it will only come from the escalation of violence in social conflicts with social reformers — revolutionaries — facing reactionary resistance during a time of rapid and severe deterioration of the environmental conditions necessary for human survival.

Since every creature and form-of-life has an instinct and will for survival, the possibility of such extinction will ultimately never deter revolutionaries motivated by global warming climate change, if they determine that the forces of reaction are implacable. Better then to die fighting than relinquish life, liberty and volition, to exploitation and annihilation by the global warming death-cult of intransigent reactionary domination.

As the conditions of life deteriorate for more and more people, an increasing number of them will be willing to make more desperate choices on the conduct of their lives, and on the conduct of their social advocacies.

The optimistic realization here — which is certainly utopian — is that we already have it in our power, as a collective, to make life whole for everybody. We only have to unite together in the choice to do so.

Premature human extinction is only as inevitable as the degree of our commitment to being intransigent in our fractious class-based and bigoted opposition to the species-wide social improvements necessary for our so-called civilization to be reformulated for the equitable benefit of all.

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:

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

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.
