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.

Possible Future Trends of CO2 Concentration and Global Temperature

Possible Future Trends of CO2 Concentration and Global Temperature

Carbon dioxide gas (CO2) has been accumulating in the atmosphere since the dawn of the Industrial Revolution (~1750), because increasingly voluminous fluxes of that gas have been exhausted from the lands and the oceans, and are beyond the capacity of natural CO2 sinks to absorb completely.

Prior to the Industrial Revolution, carbon would cycle through a variety of processes that sustained the continuation of life, death, evolution and rebirth, and that all meshed into one grand balance. That balance is called the Carbon Cycle.

The explosive growth of human activity, numbers, exosomatic power, economic wealth, military overkill, and hubristic political pretensions, all spring from the access to and profligate use of heat-energy liberated from fossil fuels. Carbon dioxide is the exhaust fume from our Promethean exertions for greater conquests — and wealth.

The carbon dioxide exhausted by our civilization’s generation of heat-energy, and from our massive exploitation of once virgin land areas, is an increasingly destabilizing perturbation of the Carbon Cycle. This perturbation is called Anthropogenic Emissions.

The imbalance of the Carbon Cycle reverberates through the natural world in many ways that are increasingly harmful and dangerous to Planet Earth’s habitability for ourselves and for many other animal and plant species. The central reality of this complex of growing threats to the viability of the Biosphere is called Global Warming.

Carbon dioxide gas traps heat radiated towards space, as infrared radiation from the surface of Planet Earth, reducing our planet’s ability to regulate its temperature by cooling to compensate for the influx of solar light that is absorbed by the lands and the oceans, and stored by them as heat.

End Game for Green Utopia

End Game for Green Utopia

On these two opposing types of responses to the movie “Planet Of The Humans”:

PRO: “The key, however, is that all these [‘greenish’] energy policies have to be carried out after capitalism has been wiped out and under conditions where production is based strictly on use.“

CON: “This documentary is trashy fake news. It’s Trumpian in its disdain for the facts…, they point away from real climate action solutions (such as renewable energy infrastructure) and peddle fascist snake oil of population growth i.e. advocate ecofascist genocide…Meanwhile, those of us who aren’t raving ecofascist lunatics will continue to fight to change society.”

Dreams of Utopias and illusions of self-importance die hard, even in the face of reality. Nature doesn’t care about how we fantasize; it just keeps on with its grand cycles, which those of global heating, environmental destruction and species extinction are now overstimulated by us, homo sapiens. The fundamental question here is: how good of an equitable world society could we energetically have, and by ‘greening it’ can we limit global warming?

PART 1:

The best we could possibly do would be to equalize the standard of living (Human Development Index) worldwide to HDI=0.862 (the range is from 0.28 for the poorest, to 0.97 for the richest nations), with a per capita electrical energy use of u=4000 kWh/c (kilowatt-hours-per-year/capita). The world average by nation (in 2002, and similar now) was: HDI=0.741 at u=2465 kWh/c. The U.S.A. had HDI=0.944 at u=13,456 kWh/c (a rich highly developed country). Niger had HDI=0.281 at u=40kWh/c (a poor underdeveloped country).

Climate Change Action Would Kill Imperialism

Climate Change Action Would Kill Imperialism

Climate change action would kill imperialism, and that is why we can’t have it in America.

American political power is based on fossil fuels, and the US military is the engine that consumes those fuels to produce that power. So long as there is an American political elite that craves lucrative personal prestige and the ability to dominate internationally, the US economy will be fossil-fueled capitalism that maintains the military colossus that enables and protects those elite ambitions.

US military-enabled imperial power is of two varieties:

first: the hard power that overtly invades and seeks to control territory to impose American capitalist domination, as for example capturing pipeline routes south through Afghanistan and Pakistan–away from China–out of Central Asian oil fields; the guarding of sea lanes crucial for petroleum transport west, as at Suez and the Strait of Hormuz, and east to Japan, Korea and Australia (if they behave); and the securing of scarce metal ore and rare earth deposits in Afghanistan and Africa (for elements used in solid state electronics); and

second: the soft power of buying compliance to US hegemony from client states by gifting them with arms sales that enable them to exercise their own mini-imperialistic ambitions, as with Israel’s threat-projection in the Levant that is consistent with US aims of regional control, and Zionism’s own manifest destiny colonialist mania of persecuting the occupied Palestinians and shrinking their reservations; and with arms sales to Saudi Arabia enabling its genocidal war against Yemen, and giving the U.S. leverage to induce the opulent Saudi royalty to keep oil production high and oil prices low on the world market, so as to grease Western capitalism and also undercut the revenue streams supporting Venezuelan socialism and Iranian economic development.

Hurricane Florence, 9-11 Climate Change Terrorism

Hurricane Florence, 9-11 Climate Change Terrorism

NEW 9-11 TERRORIST ATTACK!!

Yes, it’s true! On 11 September 2018, terrorists based in Washington D.C., and sponsored by the dinosaur bones mining, pumping and burning industries, have relaxed rules restricting methane emissions from mines and oil and gas wells (for privatized profits at socialized costs), which will result in enhanced hydrocarbon atmospheric pollution that will accelerate Global Warming.

AND JUST IN TIME!

Because Hurricane Florence, currently a Category 4 hurricane (and possibly strengthening toward the maximum possible, Category 5) is barreling down on North Carolina (a good choice, they voted for Trump), and 1.5 MILLION people have been urged/ordered to evacuate from coastal areas.

Hurricane Florence is being amplified by Climate Change (Global Warming) because:

1) the sea level is now higher (by about 1 foot in the western Atlantic near the Carolinas) because of previous ice cap melting and runoff (and heat-induced expansion of seawater), so the “storm surge” (like an extra super duper high tide) flooding of coastal lowlands, swept in by the hurricane, will be more extensive (i.e. worse); and

2) because the ocean is warmer (by Global Warming) and thus has much more energy (heat) available to pump up wind speed/energy in hurricanes, and so they have more capacity to destroy structures and infrastructure (like telephone and power poles, and fallen power lines start fires; also to uproot trees, smash houses and lift off roofs); and

3) because Global Warming/Climate Change has altered the path of the Jet Stream —

the high-latitude, high-speed, high-altitude, west-to-east ring of wind current that normally pushes Atlantic hurricanes eastward back out into the Atlantic Ocean, away from the US East Coast —

(has altered the path of the Jet Stream) farther to the north, so it now DOES NOT push Atlantic hurricanes toward the east, away from the US East Coast.

Climate Change Bites Big Business

Climate Change Bites Big Business

“Electoral politics is not the solution to the Earth-threatening problems we face.”

– Jeffrey St. Clair, 10 August 2018, Counter Punch

There is now no non-violent way to reverse climate change. Even with morally unrestrained action, it is probable that there is now no physical possibility of reversing climate change. The time for action was 1973-1979, the time of the two oil embargoes (the post Israeli War – against Egypt and Syria – Arab Oil Embargo of 1973; and the related-to-the-Iranian-Revolution vengeful price gouge oil embargo of 1979). This was the period of the Watergate-climax finale of the Nixon Administration, the Ford Administration, and the Carter “energy crisis” Administration. Politically, the election of Ronald Reagan in 1980 killed the possibility of US climate change action.

From Reagan through Bush I, Clinton, Bush II and Obama to Trump, the mentioning of climate change – as one of government’s highest priorities, as one of corporate America’s foremost concerns (to be addressed, not suppressed), and as one of mainstream media’s primary and continuing focuses and leading stories – was minimized if not altogether absent. If anything, climate change denialism was heavily promoted by corporate and partisan (right wing) media, and by legions of corporate agents, flacks and factotums masquerading as elected representatives in federal and state governments. That has now changed.

Climate change is now all over the front pages of the newspapers and is the headline story of the mainstream mass media, primarily because of the massive fires in California whose smoke has even reached New York City. Why this new overt and blaring mainstream news attention to climate change, a subject that was officially hush-hush, trivial and fake news so recently in the past? Obviously because climate change has begun costing big money to major sectors of American capitalism.

Societal Death or Transfiguration? Cinema Visions of Humanity Facing Extinction

Societal Death or Transfiguration? Cinema Visions of Humanity Facing Extinction

Still from “Downsizing.”

How should world society respond to the approach of human extinction compelled by implacable external forces, such as: radioactive fallout after a global nuclear war (as in Nevil Shute’s novel On the Beach), or an alien invasion by a species of technologically superior beings from outer space, or an impending collision between Earth and a massive planetoid, or (as seems most likely today) by runaway and irreversible Climate Change?

The general question has long been the seed for spinning out entertaining speculations in fantasy novels and science-fiction movies, but now it has become a serious matter of immediate concern for an increasing number of geo- and social- scientists and social planners. Mayer Hillman, an 86-year-old social scientist, urban planner and senior fellow emeritus of the Policy Studies Institute in England, says (in an article published by The Guardian on 26 April 2018:

“We’re doomed. — The outcome is death, and it’s the end of most life on the planet because we’re so dependent on the burning of fossil fuels. There are no means of reversing the process which is melting the polar ice caps. And very few appear to be prepared to say so. — I’m not going to write anymore [about the projected consequences of runaway Climate Change] because there’s nothing more that can be said. — With doom ahead, making a case for cycling as the primary mode of transport [instead of automobiles] is almost irrelevant. — We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness.

An Oceanic Problem: the Atlantic Overturning Current is Slowing

An Oceanic Problem: the Atlantic Overturning Current is Slowing

Photo by Michael Mayer | CC BY 2.0

The Atlantic Overturning Current is part of a worldwide twisted loop of ocean water, called the thermohaline cycle (thermo = heat, haline = salt), which emerges very salty and warm out of the Gulf of Mexico, travels north as a surface current along the east coast of North America, veers east in the North Atlantic toward Europe, then loops back west to a region just south of Greenland where it cools and sinks to the ocean floor – because it has become denser than the surrounding and less salty North Atlantic waters (colder water is denser than warmer water, and saltier water is denser than fresher water of equal temperature). The dense highly salted descending water then runs as a cold deep ocean current south along the east coast of South America, and continues in a complicated path along the ocean floor into the Pacific Ocean, where it warms and eventually rises to become a surface current of more buoyant less salty water. This current distributes solar heat collected by ocean waters in tropical latitudes to higher latitudes (closer to the poles).

In 2004, Peter Schwartz and Douglas Randall described the thermohaline cycle this way: “In this thousand-year cycle, water from the surface in tropical areas becomes more saline through evaporation. When it circulates to the poles and becomes cold (“thermo”), the greater density still present from higher salt (“haline”) concentration causes the water to sink to great depths. As with most large-scale geological processes, the thermohaline cycle is not thoroughly understood. Wallace Broecker has been studying the cycle for decades and, according to the December 1996 issue of Discover magazine, he has shown that the thermohaline cycle has not always been in operation, and that it has a strong effect on global climate.”

The Anthropocene’s Birthday, or the Birth-Year of Human-Accelerated Climate Change

February 22, 2018

The Anthropocene’s Birthday, or the Birth-Year of Human-Accelerated Climate Change

Scientists have found a major spike in the amount of Carbon-14 within the tree rings of “The Loneliest Tree In The World,” which ring corresponds to October-December 1965.

This tree is a Sitka Spruce, a species from the American Northwest (and into Canada) that was planted on Campbell Island in 1901 (or 1905), which island is in the Southern Ocean about 400 miles south of the southern tip of New Zealand.

There are no other trees on Campbell Island, just low scrubs. Since the next landmass south of Campbell Island is Antarctica, this tree is the furthest one south on Earth (so far as I can tell). The next closest tree is north about 170 miles, on another small island south of New Zealand.

The significance of this finding is that geologists now know that the start of the Anthropocene – which is the geological period when GLOBAL (not just local) climate is clearly being influenced by human activity and at an accelerating rate – began in 1965.

The Carbon-14 marker is from the radioactive fallout from atmospheric nuclear bomb testing, which grew from 1945 and peaked in 1962, after which it stopped (except for a few isolated atmospheric tests since) in 1963 as a result of the Test Ban treaty of that year.

The accumulated radioactive fallout from the massive testing of the 1950s and early 1960s (with a huge amount in 1962) had finally spread out uniformly through the global atmosphere, and the Carbon-14 from that fallout was being infused into trees globally through the process of photosynthesis.

So, this spike in tree-ring Carbon-14 in 1965 is a GLOBAL marker of human activity on global climate, and thus is the birthday of human-induced/accelerated Climate Change.
