You Can’t Sue Fossil Fuel Industry Over Climate Change

”Turns out cities can’t sue oil companies for climate change” reads the title of an article in Wired.Com magazine (https://www.wired.com/story/climate-lawsuits-dismissed/).* Well, obviously; the purpose of the US judiciary is to protect massed capital from popular democracy.

The truth is that climate change denial is primarily a failure of the U.S. Government (and other governments), from – at a minimum – the Reagan and then George H. W. Bush Administrations. Government scientists as well as government supported academics in the meteorological/atmospheric, oceanic, geological, and energy sciences all had combinations of observational data and computer models that clearly showed the advance and effects of global warming/climate change. The first definitive modern peer-reviewed scientific publication (in the journal Nature) describing the mechanism of CO2-caused global warming (the inability of the oceans to absorb all the CO2 being emitted, hence its buildup in the atmosphere, hence the growing heat retention by the CO2-laced atmosphere, hence the continuing rise in average air-ocean-earth temperature) was published in 1955.

By 1988, when James Edward Hansen (NASA’s chief scientist on atmospheric modeling and global warming at that time) gave his testimony to Congress – stating that global warming was man-made by CO2 emission – essentially all physically and mathematically reasonable computer models of the atmosphere and/or oceans, internationally, gave the same overall result: the more CO2 in the atmosphere, the higher the global average temperature; and the observed rise in global average temperature with time tracked the rate of increase of CO2 (and other organic gases and vapors) in the atmosphere. The National Academy of Sciences, as well as every real scientific and engineering professional society also agrees with this conclusion and states so.

The failure of protecting the public interest falls squarely on the political leadership class, who populate succeeding administrations of the USG and who collectively chose not to face the obvious facts presented by America’s (and the world’s) scientists, because that political leadership class did not want to accept or act on the clear societal implications of the scientific facts. Why? because the political leadership was more concerned to protect the financial self-interests of currently entrenched and very wealthy capitalist combines (in particular fossil fuel industries and the financial industries associated with them) than it was concerned to protect the long-term interests of the majority of the public for survival and well being (workers, wage earners, “ordinary people” relatively few of whom one could consider as “investors” in stocks, bonds and paper securities).

In brief, our politicians have for decades preferred to sell out the long term survival (and sustainable prosperity) of “the people” in favor of protecting the exploitative profitability of capital-intensive CO2-polluting industry and economic gamesmanship, and the super-wealthy (who are invariably corporatists and investor/speculators banking on those capital-intensive CO2-polluting industries). So, while it is true that the energy companies were very deceitful in funding P.R. campaigns of climate change denial while their own scientists/technologists knew that climate change was real and caused as a result of using their fossil fuels – just to keep raking in huge short-term profits – we had ample ways of knowing the truth without needing the fossil fuel companies to admit it, because we have had the publicly funded and publicly available scientific results of world-wide modern geo-science for decades.

American cities trying to sue energy companies for lying about climate change and hence “causing” damage to such municipalities has some legal logic to it as a way for these cities to “recover” financial compensation for their climate change-related “damages.” However, as noted here that is really a rather limited, petty, and at least partly hypocritical finger-pointing response to the accelerating climate change crisis, because that crisis is essentially the direct consequence of a willful (intentional!) failure of American (and other national) government, which was in cahoots with the CO2 polluter industries (and especially the Pentagon) and related finance capital industries.

Basically, capitalism is a fossil-fueled political-economic parasite feeding off the public good, both in its societal and environmental dimensions, and the US government (and others with similar energy and finance capital policies) is entirely in the business of protecting capitalism (the economic parasites) against the personal and societal interests of the majority of the national population (e.g., the ensuring of sustainable environmental security and long-term habitability, and having national political power controlled by popular and populist democracy rather than institutions of concentrated wealth).

And that’s where it stands today. We are on an accelerating plunge into extinction by climate change induced disasters (vast wildfires, collapsing agriculture, desertification and the poisoning of aquifers, the expanding range of disease pathogens, very destructive wind and rain storms) from the bottom up (first the poorest, last the richest) driven by a mad obsession to further concentrate the financial wealth of the wealthiest. It’s really all just a mass psychosis, and all our wars and military rivalries (nuclear armed no less) and political forms of oppression, repression and cruelty, and all our myopically fanatical exercises for maintaining control of factional and personal advantages parasitic to the public good are just ripples on the surface of the one great oceanic reality of our time: the survival of organized human life in the face of accelerating (and still out of our control) climate change.

Collectively, we humans just don’t want to face the fact that to have any useful (for our survival, and for social equity) impact on the present course of climate change we would have to change EVERYTHING, and NOW. Hypothetically, humanity has the capacity to do this, but realistically, based on the observation of past human behavior, it seems that the high degree of long-term cooperative altruism required to make such a complete change of world society (i.e., “the revolution,” or the “instant” conscious evolution of humanity’s super-ego) may be beyond the capacity of our collective social psychology. For now we each remain the randomly surprised victims of the sporadic disasters that erupt from our accumulating karma of obsessive-compulsive fossil-fueled climate change denial.

As an engineer, the only wild-ass guess of a solution that I can think of today is to hope for a miraculous “world satori” – a collective spontaneous and consensus-forming waking up of “everyone” to the same new vision of world society – and this then leading to our world buckling down to doing the numerous (and monumental) technical tasks of transforming all the structures of our civilization into a new paradigm in harmony with nature. Admittedly, this is an extremely fuzzy and rarefied engineering solution. What’s your idea?

Your Genetic Presence Through Time

The propagation through time of your personal genetic presence within the genetic sea of humanity can be visualized as a wave that arises out of the pre-conscious past before your birth, moves through the streaming present of your conscious life, and dissipates into the post-conscious future after your death.

You are a pre-conscious genetic concentration drawn out of the genetic diffusion of your ancestors. If you have children who survive you then your conscious life is the time of increase of your genetic presence within the living population. Since your progeny are unlikely to reproduce exponentially, as viruses and bacteria do, your post-conscious genetic presence is only a diffusion to insignificance within the genetic sea of humanity.

During your conscious life, you develop a historical awareness of your pre-conscious past, with a personal interest that fades with receding generations. Also during your conscious life, you can develop a projective concern about your post-conscious future, with a personal interest that fades with succeeding generations and with increasing predictive uncertainty.

Your conscious present is the sum of: your immediate conscious awareness, your reflections on your prior conscious life, your historical awareness of your pre-conscious past, and your concerns about your post-conscious future.

Your time of conscious present becomes increasingly remote in the historical awareness of your succeeding generations.

Your loneliness in old age is just your sensed awareness of your genetic diffusion into the living population of your conscious present and post-conscious future.

To present the above ideas in a simple quantitative way, consider a model human population in which:

— every individual lives 75 years,

— at age 25, every individual mates and produces 2 children.

In this model, reproductive mating is assumed to produce 2 children so as to maintain a stable population by adding one replacement each for the mother and father (who only have one reproductive mating per lifetime; but any number of non-reproductive matings are allowed).

So, 175 years prior to the birth of a model individual here, 128 ancestors (ggggg-grandparents) are born. The genetic concentration leading to the target model individual proceeds forward with the birth of 64 gggg-grandparents 150 years prior to the birth of the target individual; 32 ggg-grandparents 125 years prior; 16 gg-grandparents 100 years prior; 8 great-grandparents 75 years prior; 4 grandparents 50 years prior; and 2 parents 25 years prior.

During conscious life the target individual has 2 children when at age 25, acquires 4 grandchildren when at age 50, and acquires 8 great-grandchildren when at age 75, when he/she dies. The number of progeny increases during the post-conscious future of the target individual, with a diminishing portion of the target individual’s genes in each descendant as their generation number increases.

You can see from the Table that you would have very little genetic connection with ancestors older than your great-grandparents (earlier than generation -3, or 75 years before “your” birth, in the model above), and thus (usually) a diminished interest in family history before that time.

Your most closely related other individual(s) is(are) your brother or sister (a twin in the model), with whom you share 100% of your genetic sources: 50% from your mother, and 50% from your father, for each of you, though your father’s mix may be different between the siblings, as well as the mother’s mix being different between the siblings. Identical twins would have identical paternal mixes, and identical maternal mixes.

You can see that for progeny beyond the +3 generation, your great-great-grandchildren, your genetic contribution is minor, and so your concerns about such distant future progeny (beyond 25 years after your death) is usually diminished.

So, the 175 year interval of human history that you (as a model individual, as above) would most likely have the greatest personal interest in would include the 75 years prior to your birth (your ancestors’ histories), the 75 years of your model lifetime (your conscious life), and the first 25 years of your post-conscious future (during times of conscious living for your children, grandchildren and great-grandchildren).

In summary: You are genetically concentrated from the pre-conscious past, genetically prominent in the conscious present, and genetically diffused into the post-conscious future.

ADDENDUM, 15 June 2018

One can formulate a normalized genetic presence (NGP) parameter as follows (which I describe as it is applied to the specific population model used earlier):

(1) For your pre-conscious time, at each generation divide your potential genetic presence (which is equal to 1) by the number of ancestors (carriers) born at that generation. This will be a fraction, and we call it your potential genetic presence because it occurs prior to your live birth.

(2) For your conscious life time, at each generation form the sum of (a) + (b):

(a) your living genetic presence, which is defined as the ratio of your total genetic complement divided by the number of organisms carrying them. This number is 1/1 = 1 while you are alive, and it is zero after you die.

(b)  the sum of your transmitted genes, normalized by the number of your LIVING progeny, as follows:

— 2 children are each 50% carriers of your genes, thus there are 2 organisms carrying a total of 1 genetic presence of you (jumbled, of course), thus: 1/2 = 0.5, (from your 25th to 100th year, in the model), PLUS

— 4 grandchildren who are each 25% carriers of your genes, so there are 4 organisms carrying another 1 genetic presence of you (jumbled, of course), thus 1/4 = 0.25 (from your 50th to 125th year, in the model), PLUS

— 8 great-grandchildren who are each 12.5% carriers of your genes, so there are 8 organisms carrying another 1 genetic presence of you (jumbled, of course), thus 1/8 = 0.125 (for a brief time during your 75th year, as “you” die then in the model; they continue to your 150th year),

(3) For your post-conscious time, your NGP equals the transmitted genetic presence carried by your living progeny:

— after “your” (model) death, you continue to calculate transmitted genetic presence factors for advancing generations of your LIVING progeny by a similar logic to the previous steps.

The following TABLE 2, and graph, show the NGP over time of a target individual in the model used previously.

The Atlantic Overturning Current Is Slowing

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

The Atlantic Overturning Current Is Slowing

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.”

In 2003-2004, the US Department of Defense commissioned a secret study of what might be the worst possible effects of Global Warming triggering an “abrupt climate change” in the near future, in order to estimate the potential liabilities that military planning would have to consider (to maintain US security, and global power). This study was conducted during the climate-change-denying George W. Bush Administration. When the existence of the resulting report, produced by independent researchers Peter Schwartz and Douglas Randall, became publicly known there was such a public outcry (bad PR for the DOD) that the report was declassified and made publicly available.

The Schwartz-Randall report pointed to the abrupt onset of a significantly colder, dryer climate in the Northern Hemisphere as the most perilous possible consequence of Global Warming up to about 2010, because such warming (the trapping of incoming solar radiation and outgoing infrared radiation from the land and oceans, by greenhouse gases in the atmosphere) might cause the thermohaline cycle to stop. How? Global Warming causes glaciers and ice caps to melt, and such fresh (unsalted) meltwater from Greenland floods into the North Atlantic where the thermohaline current dives to the ocean floor. This fresh surface water dilutes the high salinity of the presently descending thermohaline current, making its waters less dense (less heavy) and so less likely to sink. Sufficient freshening of the thermohaline current would cause it to stop entirely, shutting off this global conveyor belt of climate-regulating oceanic solar heat.

Though abrupt climate change is a less likely and worst case scenario as compared to gradual climate change, Schwartz and Randall concluded that such an occurrence would “challenge United States national security in ways that should be considered immediately.” The climatic cooling that might occur in the Northern Hemisphere as a result of a collapse of the thermohaline cycle could be like the century-long period 8,200 years ago with temperature 5 °F (2.8 °C) colder, or the 13 century-long period 12,700 years ago with temperature 27 °F (15 °C) colder. The shift to colder climate could occur as rapidly as 5 °F (2.8 °C) of cooling per decade. So, the world could plunge into a new Ice Age within a period of twenty years. In their 2004 report, Schwartz and Randall showed data on the salinity of the North Atlantic since 1960; the trend was a steady freshening. (I wrote about the above in an article for the Internet, in July 2004).

A 2015 scientific publication of new observations on the “Atlantic Meridional Overturning Circulation” (the Atlantic part of our thermohaline cycle) concluded that “the melting Greenland ice sheet is likely disturbing the circulation.” The Phys.org news article (https://phys.org/news/2015-03-atlantic-ocean-overturning-today.html) about this study [Rahmstorf, S., Box, J., Feulner, G., Mann, M., Robinson, A., Rutherford, S., Schaffernicht, E. (2015): “Evidence for an exceptional 20th-Century slowdown in Atlantic Ocean overturning.” Nature Climate Change (the journal)] concluded:

“The scientists certainly do not expect a new ice age, thus the imagery of the ten-year-old Hollywood blockbuster ‘The Day After Tomorrow’ is far from reality. However, it is well established that a large, even gradual change in Atlantic ocean circulation could have major negative effects. ‘If the slowdown of the Atlantic overturning continues, the impacts might be substantial,’ says Rahmstorf. ‘Disturbing the circulation will likely have a negative effect on the ocean ecosystem, and thereby fisheries and the associated livelihoods of many people in coastal areas. A slowdown also adds to the regional sea-level rise affecting cities like New York and Boston. Finally, temperature changes in that region can also influence weather systems on both sides of the Atlantic, in North America as well as Europe.’ If the circulation weakens too much it can even break down completely – the Atlantic overturning has for long been considered a possible tipping element in the Earth System. This would mean a relatively rapid and hard-to-reverse change.”

On April 11, 2018, an article titled “Stronger evidence for a weaker Atlantic overturning” appeared at Phys.org (https://phys.org/news/2018-04-stronger-evidence-weaker-atlantic-overturning.html). This article notes:

“The Atlantic overturning—one of Earth’s most important heat transport systems, pumping warm water northward and cold water southward—is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the 20th century, according to a study published in the highly renowned journal Nature by an international team of scientists. Human-made climate change is a prime suspect for these worrying observations. There have been long debates whether the Atlantic overturning could collapse, being a tipping element in the Earth system. The present study does not consider the future fate of this circulation, but rather analyses how it has changed over the past hundred years. Nevertheless, Robinson cautions: ‘If we do not rapidly stop global warming, we must expect a further long-term slowdown of the Atlantic overturning. We are only beginning to understand the consequences of this unprecedented process—but they might be disruptive.’ Several studies have shown, for example, that a slowdown of the Atlantic overturning exacerbates sea-level rise on the US coast for cities like New York and Boston. Others show that the associated change in Atlantic sea surface temperatures affects weather patterns over Europe, such as the track of storms coming off the Atlantic. Specifically, the European heat wave of summer 2015 has been linked to the record cold in the northern Atlantic [caused by the inflow of cold Greenland meltwater] in that year—this seemingly paradoxical effect occurs because a cold northern Atlantic promotes an air pressure pattern that funnels warm air from the south into Europe.”

While the scientists are not being alarmist Jeremiahs and warning of an imminent climapocalypse as depicted in the Hollywood movie “The Day After Tomorrow,” they nevertheless make it clear that if this Global Warming caused (fossil-fuel-burning human caused) slowing of the thermohaline cycle continues to the point of a dead stop, then this would likely be a tipping point of the entire Earth System of climate leading to “a relatively rapid and hard-to-reverse change” — not for the better.

Einstein-Hawking-Pi Day #1

March 14 is given the name “Pi Day” by many mathematics enthusiasts because the numerical calendar label “3/14,” for the month (March) then day (the 14th), coincides with the first three digits of the irrational number Pi, 3.14159…

I have called today, the 14th of March, 2018, “Einstein-Hawking-Pi Day #1” because it is the first instance of the triple ‘resonance’ of: an anniversary of Albert Einstein’s birthday, the actual date of Stephen Hawking’s death, and a Pi Day.

I commemorated the day by taking photographs of living eternity, that is to say eternal (so far as we are concerned) principles expressing themselves in radiant instants of life-giving beauty.

I added 10 of these photos (at maximum resolution) to my Flickr site, for display. They are the first ten scenics “from top down” at the following webpage. You can view them, and get technical details there.

The Anthropocene’s Birthday

The Anthropocene’s Birthday, or the birthyear 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 Epoch (after the Holocene Epoch) when GLOBAL (not just local) climate is clearly being influenced by human activity and at an accelerating rate – began in 1965. The Holocene Epoch occurred from -11,700 to 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 in 1963 as a result of the Test Ban treaty of that year (except for a few isolated atmospheric tests since).

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 marks the ‘birthday’ of human-induced/accelerated Climate Change.

Coring “the loneliest tree in the world”
https://youtu.be/954fZW9F3tQ

The geophysical transition of 1965, noted above, was imperceptible to the human senses, but it is a very significant event/transition in the history of Planet Earth.

You should easily be able to find internet sources giving all the scientific details including charts/graphs of the actual Carbon-14 signature (of the subject tree) over time, which clearly displays the spike during 1965. This same spike was found in trees sampled in the Northern Hemisphere as well, and since there was the same marker on trees globally – for the first time – it was clear the spike indicated a uniformly global effect. And that effect was caused by humans. Hence, the birth of the Anthropocene.

Geologists are now updating their table of geological supereon-eon-era-period-epoch-age, and all textbooks will have to be updated. The last Epoch (the Holocene) of the Quaternary Period extended from 11,700 years ago, when the last glacial retreat was clearly accelerating and the Ice Ages were over, and 1965 when humanity now had leverage on the global climate: the Anthropocene.

When will the next Epoch begin, and how will it be determined (and will there be any ‘who’ to do so)?

In 1942, Swedish physicist and engineer Hannes Alfvén presented his theory of hydromagnetic waves, for which he won the Nobel Prize in physics in 1970. Between 1983 and 1985, I tried to convince my supposed colleagues and science-bureaucrat superiors (timorous bosses and climbers at Livermore, and also Los Alamos) to study this type of magnetic wave phenomenon, after I found ample evidence of it in very elaborate computer simulations of nuclear explosions (simulations of which was all they knew how to do) driving moderately relativistic magnetohydrodynamics (which they did not recognize nor understand at all). So, I enjoyed reading about the new advances in hydromagnetic wave physics made by the Queen’s University Belfast. My cartoon physics monograph on the subject (to the extent I could understand it), from 1983-1985, is available at my blog under the title “Proton Beam Driven Electron MHD.” One of my favorite works ever.

The Thermodynamics of 9-11

When hijacked airliners crashed into the tall Towers of the World Trade Center, in New York City [on 11 September 2001], each injected a burning cloud of aviation fuel throughout the 6 levels (WTC 2) to 8 levels (WTC 1) in the impact zone. The burning fuel ignited the office furnishings: desks, chairs, shelving, carpeting, work-space partitions, wall and ceiling panels; as well as paper and plastic of various kinds.

How did these fires progress? How much heat could they produce? Was this heat enough to seriously weaken the steel framework? How did this heat affect the metal in the rubble piles in the weeks and months after the collapse? This report is motivated by these questions, and it will draw ideas from thermal physics and chemistry. My previous report on the collapses of the WTC Towers described the role of mechanical forces (1).

Summary of National Institute of Technology and Standards (NIST) Report

Basic facts about the WTC fires of 9/11/01 are abstracted by the numerical quantities tabulated here.

Table 1, Time and Energy of WTC Fires

ITEM                              WTC 1           WTC 2
impact time (a.m.)          8:46:30          9:02:59
collapse (a.m.)               10:28:22        9:58:59
time difference               1:41:52          0:56:00
impact zone levels          92-99            78-83
levels in upper block       11                 27
heat rate (40 minutes)     2 GW            1 GW
total heat energy             8000 GJ       3000 GJ

Tower 1 stood for one hour and forty-two minutes after being struck between levels 92 and 99 by an airplane; the block above the impact zone had 11 levels. During the first 40 minutes of this time, fires raged with an average heat release rate of 2 GW (GW = giga watts = 10^9 watts), and the total heat energy released during the interval between airplane impact and building collapse was 8000 GJ (GJ = giga-joules = 10^9 joules).

A joule is a unit of energy; a watt is a unit of power; and one watt equals an energy delivery rate of one joule per second.

Tower 2 stood for fifty-six minutes after being struck between levels 78 and 83, isolating an upper block of 27 levels. The fires burned at a rate near 1 GW for forty minutes, diminishing later; and a total of 3000 GJ of heat energy was released by the time of collapse.

WTC 2 received half as much thermal energy during the first 40 minutes after impact, had just over twice the upper block mass, and fell within half the time than was observed for WTC 1. It would seem that WTC 1 stood longer despite receiving more thermal energy because its upper block was less massive.

The data in Table 1 are taken from the executive summary of the fire safety investigation by NIST (2).

The NIST work combined materials and heat transfer lab experiments, full-scale tests (wouldn’t you like to burn up office cubicles?), and computer simulations to arrive at the history and spatial distribution of the burning. From this, the thermal histories of all the metal supports in the impact zone were calculated (NIST is very thorough), which in turn were used as inputs to the calculations of stress history for each support. Parts of the structure that were damaged or missing because of the airplane collision were accounted for, as was the introduction of combustible mass by the airplane.

Steel loses strength with heat. For the types of steel used in the WTC Towers (plain carbon, and vanadium steels) the trend is as follows, relative to 100% strength at habitable temperatures.

Table 2, Fractional Strength of Steel at Temperature

Temperature, degrees C      Fractional Strength, %
200                                     86
400                                     73
500                                     66
600                                     43
700                                     20
750                                     15
800                                     10

I use C for Centigrade, F for Fahrenheit, and do not use the degree symbol in this report.

The fires heated the atmosphere in the impact zone (a mixture of gases and smoke) to temperatures as high as 1100 C (2000 F). However, there was a wide variation of gas temperature with location and over time because of the migration of the fires toward new sources of fuel, a complicated and irregular interior geometry, and changes of ventilation over time (e.g., more windows breaking). Early after the impact, a floor might have some areas at habitable temperatures, and other areas as hot as the burning jet fuel, 1100 C. Later on, after the structure had absorbed heat, the gas temperature would vary over a narrower range, approximately 200 C to 700 C away from centers of active burning.

As can be seen from Table 2, steel loses half its strength when heated to about 570 C (1060 F), and nearly all once past 700 C (1300 F). Thus, the structure of the impact zone, with a temperature that varies between 200 C and 700 C near the time of collapse, will only have between 20% to 86% of its original strength at any location.

The steel frames of the WTC Towers were coated with “sprayed fire resistant materials” (SFRMs, or simply “thermal insulation”). A key finding of the NIST Investigation was that the thermal insulation coatings were applied unevenly — even missing in spots — during the construction of the buildings, and — fatally — that parts of the coatings were knocked off by the jolt of the airplane collisions.

Spraying the lumpy gummy insulation mixture evenly onto a web of structural steel, assuming it all dries properly and none is banged off while work proceeds at a gigantic construction site over the course of several years, is an unrealistic expectation. Perhaps this will change, as a “lesson learned” from the disaster. The fatal element in the WTC Towers story is that enough of the thermal insulation was banged off the steel frames by the airplane jolts to allow parts of frames to heat up to 700 C. I estimate the jolts at 136 times the force of gravity at WTC 1, and 204 at WTC 2.

The pivotal conclusion of the NIST fire safety investigation is perhaps best shown on page 32, in Chapter 3 of Volume 5G of the Final Report (NIST NCSTAR 1-5G WTC Investigation), which includes a graph from which I extracted the data in Table 2, and states the following two paragraphs. (The NIST authors use the phrase “critical temperature” for any value above about 570 C, when steel is below half strength.)

“As the insulation thickness decreases from 1 1/8 in. to 1/2 in., the columns heat up quicker when subjected to a constant radiative flux. At 1/2 in. the column takes approximately 7,250 s (2 hours) to reach a critical temperature of 700 C with a gas temperature of 1,100 C. If the column is completely bare (no fireproofing) then its temperature increases very rapidly, and the critical temperature is reached within 350 s. For a bare column, the time to reach a critical temperature of 700 C ranges between 350 to 2,000 s.

“It is noted that the time to reach critical temperature for bare columns is less than the one hour period during which the buildings withstood intense fires. Core columns that have their fireproofing intact cannot reach a critical temperature of 600 C during the 1 or 1 1/2 hour period. (Note that WTC 1 collapsed in approximately 1 1/2 hour, while WTC 2 collapsed in approximately 1 hour). This implies that if the core columns played a role in the final collapse, some fireproofing damage would be required to result in thermal degradation of its strength.” (3)

Collapse

Airplane impact sheared columns along one face and at the building’s core. Within minutes, the upper block had transferred a portion of its weight from central columns in the impact zone, across a lateral support at the building crown called the “hat truss,” and down onto the three intact outer faces. Over the course of the next 56 minutes (WTC 2) and 102 minutes (WTC 1) the fires in the impact zone would weaken the remaining central columns, and this steadily increased the downward force exerted on the intact faces. The heat-weakened frames of the floors sagged, and this bowed the exterior columns inward at the levels of the impact zone. Because of the asymmetry of the damage, one of the three intact faces took up much of the mounting load. Eventually, it buckled inward and the upper block fell. (1)

Now, let’s explore heat further.

How Big Were These Fires?

I will approximate the size of a level (1 story) in each of the WTC Towers as a volume of 16,080 m^3 with an area of 4020 m^2 and a height of 4 m (4). Table 3 shows several ways of describing the total thermal energy released by the fires.

Table 3, Magnitude of Thermal Energy in Equivalent Weight of TNT

ITEM                                  WTC 1              WTC 2
energy (Q)                          8000 GJ           3000 GJ
# levels                              8                       6
tons of TNT                       1912                 717
tons/level                           239                  120

kg/m^2 (impact floors)       54                    27
lb/ft^2 (impact floors)         11                    6

The fires in WTC 1 released an energy equal to that of an explosion of 1.9 kilotons of TNT; the energy equivalent for WTC 2 is 717 tons. Obviously, an explosion occurs in a fraction of a second while the fires lasted an hour or more, so the rates of energy release were vastly different. Even so, this comparison may sharpen the realization that these fires could weaken the framework of the buildings significantly.

How Hot Did The Buildings Become?

Let us pretend that the framework of the building is made of “ironcrete,” a fictitious mixture of 72% iron and 28% concrete. This framework takes up 5.4% of the volume of the building, the other 94.6% being air. We assume that everything else in the building is combustible or an inert material, and the combined mass and volume of these are insignificant compared to the mass and volume of ironcrete. I arrived at these numbers by estimating volumes and cross sectional areas of metal and concrete in walls and floors in the WTC Towers.

The space between floors is under 4 meters; and the floors include a layer of concrete about 1/10 meter thick. The building’s horizontal cross-section was a 63.4 meter square. Thus, the gap between floors was nearly 1/10 of the distance from the center of the building to its periphery. Heat radiated by fires was more likely to become trapped between floors, and stored within the concrete floor pans, than it was to radiate through the windows or be carried out through broken windows by the flow of heated air. We can estimate a temperature of the framework, assuming that all the heat became stored in it.

The amount of heat that can be stored in a given amount of matter is a property specific to each material, and is called heat capacity. The ironcrete mixture would have a volumetric heat capacity of Cv = 2.8*10^6 joules/(Centigrade*m^3); (* = multiply). In the real buildings, the large area of the concrete pads would absorb the heat from the fires and hold it, since concrete conducts heat very poorly. The effect is to bath the metal frame with heat as if it were in an oven or kiln. Ironcrete is my homogenization of materials to simplify this numerical example.

The quantity of heat energy Q absorbed within a volume V of material with a volumetric heat capacity Cv, whose temperature is raised by an amount dT (for “delta-T,” a temperature difference) is Q = Cv*V*dT. We can solve for dT. Here, V = (870 m^3)*(# levels); also dT(1) corresponds to WTC 1, and dT(2) corresponds to WTC 2.

dT(1) = (8 x 10^12)/[(2.8 x 10^6)*(870)*8] = 410 C,

dT(2) = (3 x 10^12)/[(2.8 x 10^6)*(870)*6] = 205 C.

Our simple model gives a reasonable estimate of an average frame temperature in the impact zone. The key parameter is Q (for each building). NIST spent considerable effort to arrive at the Q values shown in Table 3 (3). Our model gives a dT comparable to the NIST results because both calculations deposit the same energy into about the same amount of matter. Obviously, the NIST work accounts for all the details, which is necessary to arrive at temperatures and stresses that are specific to every location over the course of time. Our equation of heat balance Q = Cv*V*dT is an example of the conservation of energy, a fundamental principle of physics.

Well, Can The Heat Weaken The Steel Enough?

On this, one either believes or one doesn’t believe. Our simple example shows that the fires could heat the frames into the temperature range NIST calculates. It seems entirely reasonable that steel in areas of active and frequent burning would experience greater heating than the averages estimated here, so hotspots of 600 C to 700 C seem completely believable. Also, the data for WTC Towers steel strength at elevated temperatures is not in dispute. I believe NIST; answer: yes.

Let us follow time through a sequence of thermal events.

Fireball

The airplanes hurtling into the buildings with speeds of at least 200 m/s (450 mph) fragmented into exploding torrents of burning fuel, aluminum and plastic. Sparks generated from the airframe by metal fracture and impact friction ignited the mixture of fuel vapor and air. This explosion blew out windows and billowed burning fuel vapor and spray throughout the floors of the impact zone, and along the stairwells and elevator shafts at the center of the building; burning liquid fuel poured down the central shafts. Burning vapor, bulk liquid and droplets ignited most of what they splattered upon. The intense infrared radiation given off by the 1100 C (2000 F) flames quickly ignited nearby combustibles, such as paper and vinyl folders. Within a fraction of a second, the high pressure of the detonation wave had passed, and a rush of fresh air was sucked in through window openings and the impact gash, sliding along the tops of the floors toward the centers of intense burning.

Hot exhaust gases: carbon monoxide (CO), carbon dioxide (CO2), water vapor (H2O), soot (carbon particles), unburned hydrocarbons (combinations with C and H), oxides of nitrogen (NOx), and particles of pulverized solids vented up stairwells and elevator shafts, and formed thick hot layers underneath floors, heating them while slowly edging toward the openings along the building faces. Within minutes, the aviation fuel was largely burned off, and the oxygen in the impact zone depleted.

Thermal Storage

Fires raged throughout the impact zone in an irregular pattern dictated by the interplay of the blast wave with the distribution of matter. Some areas had intense heating (1100 C), while others might still be habitable (20 C). The pace of burning was regulated by the area available for venting the hot exhaust gases, and the area available for the entry of fresh air. Smoke was cleared from the impact gash by air entering as the cycle of flow was established. The fires were now fueled by the contents of the buildings.

Geometrically, the cement floors had large areas and were closely spaced. They intercepted most of the infrared radiation emitted in the voids between them, and they absorbed heat (by conduction) from the slowly moving (“ventilation limited”) layer of hot gases underneath each of them. Concrete conducts heat poorly, but can hold a great deal of it. The metal reinforcing bars within concrete, as well as the metal plate underneath the concrete pad of each WTC Towers floor structure, would tend to even out the temperature distribution gradually.

This process of “preheating the oven” would slowly raise the average temperature in the impact zone while narrowing the range of extremes in temperature. Within half an hour, heat had penetrated to the interior of the concrete, and the temperature everywhere in the impact zone was between 200 C and 700 C, away from sites of active burning.

Thermal Decomposition — “Cracking”

Fire moved through the impact zone by finding new sources of fuel, and burning at a rate limited by the ventilation, which changed over time.

Heat within the impact zone “cracks” plastic into a sequence of decreasingly volatile hydrocarbons, similar to the way heat separates out an array of hydrocarbon fuels in the refining of crude oil. As plastic absorbs heat and begins to decompose, it emits hydrocarbon vapors. These may flare if oxygen is available and their ignition temperatures are reached. Also, plumes of mixed hydrocarbon vapor and oxygen may detonate. So, a random series of small explosions might occur during the course of a large fire.

Plastics not designed for use in high temperature may resemble soft oily tar when heated to 400 C. The oil in turn might release vapors of ethane, ethylene, benzene and methane (there are many hydrocarbons) as the temperature climbs further. All these products might begin to burn as the cracking progresses, because oxygen is present and sources of ignition (hotspots, burning embers, infrared radiation) are nearby. Soot is the solid end result of the sequential volatilization and burning of hydrocarbons from plastic. Well over 90% of the thermal energy released in the WTC Towers came from burning the normal contents of the impact zones.

Hot Aluminum

Aluminum alloys melt at temperatures between 475 C and 640 C, and molten aluminum was observed pouring out of WTC 2 (5). Most of the aluminum in the impact zone was from the fragmented airframe; but many office machines and furniture items can have aluminum parts, as can moldings, fixtures, tubing and window frames. The temperatures in the WTC Towers fires were too low to vaporize aluminum; however, the forces of impact and explosion could have broken some of the aluminum into small granules and powder. Chemical reactions with hydrocarbon or water vapors might have occurred on the surfaces of freshly granulated hot aluminum.

The most likely product of aluminum burning is aluminum oxide (Al2O3, “alumina”). Because of the tight chemical bonding between the two aluminum atoms and three oxygen atoms in alumina, the compound is very stable and quite heat resistant, melting at 2054 C and boiling at about 3000 C. The affinity of aluminum for oxygen is such that with enough heat it can “burn” to alumina when combined with water, releasing hydrogen gas from the water,

2*Al + 3*H2O + heat -> Al2O3 + 3*H2.

Water is introduced into the impact zone through the severed plumbing at the building core, moisture from the outside air, and it is “cracked” out of the gypsum wall panels and to a lesser extent from concrete (the last two are both hydrated solids). Water poured on an aluminum fire can be “fuel to the flame.”

When a mixture of aluminum powder and iron oxide powder is ignited, it burns to iron and aluminum oxide,

Al + Fe2O3 + ignition -> Al2O3 + Fe.

This is thermite. The reaction produces a temperature that can melt steel (above 1500 C, 2800 F). The rate of burning is governed by the pace of heat diffusion from the hot reaction zone into the unheated powder mixture. Granules must absorb sufficient heat to arrive at the ignition temperature of the process. The ignition temperature of a quiescent powder of aluminum is 585 C. The ignition temperatures of a variety of dusts were found to be between 315 C and 900 C, by scientists developing solid rocket motors. Burning thermite is not an accelerating chain reaction (“explosion”), it is a “sparkler.” My favorite reference to thermite is in the early 1950s motion picture, “The Thing.”

Did patches of thermite form naturally, by chance, in the WTC Towers fires? Could there really have been small bits of melted steel in the debris as a result? Could there have been “thermite residues” on pieces of steel dug out of the debris months later? Maybe, but none of this leads to a conspiracy. If the post-mortem “thermite signature” suggested that a mass of thermite comparable to the quantities shown in Table 3 was involved, then further investigation would be reasonable. The first task of such an investigation would be to produce a “chemical kinetics” model of the oxidation of the fragmented aluminum airframe, in some degree of contact to the steel framing, in the hot atmosphere of hydrocarbon fires in the impact zone. Once Nature had been eliminated as a suspect, one could proceed to consider Human Malevolence.

Smoldering Rubble

Nature is endlessly creative. The deeper we explore, the more questions we come to realize.

Steel columns along a building face, heated to between 200 C and 700 C, were increasingly compressed and twisted into a sharpening bend. With increasing load and decreasing strength over the course of an hour or more, the material became unable to rebound elastically, had the load been released. The steel entered the range of plastic deformation, it could still be stretched through a bend, but like taffy it would take on a permanent set. Eventually, it snapped.

Months later, when this section of steel would be dug out of the rubble pile, would the breaks have the fluid look of a drawn out taffy, or perhaps “melted” steel now frozen in time? Or, would these be clean breaks, as edge glass fragments; or perhaps rough, granular breaks as through concrete?

The basements of the WTC Towers included car parks. After the buildings collapsed, it is possible that gasoline fires broke out, adding to the heat of the rubble. We can imagine many of the effects already described, to have occurred in hot pockets within the rubble pile. Water percolating down from that sprayed by the Fire Department might carry air down also, and act as an oxidizing agent.

The tight packing of the debris from the building, and the randomization of its materials would produce a haphazard and porous form of ironcrete aggregate: chunks of steel mixed with broken and pulverized concrete, with dust-, moisture-, and fume-filled gaps. Like a pyramid of barbecue briquettes, the high heat capacity and low thermal conductivity of the rubble pile would efficiently retain its heat.

Did small hunks of steel melt in rubble hot spots that had just the right mix of chemicals and heat? Probably unlikely, but certainly possible.

Pulverized concrete would include that from the impact zone, which may have had part of its water driven off by the heat. If so, such dust would be a desiccating substance (as is Portland cement prior to use; concrete is mixed sand, cement and water). Part of the chronic breathing disorders experienced by many people exposed to the atmosphere at the World Trade Center during and after 9/11/01 may be due to the inhalation of desiccating dust, now lodged in lung tissue.

Did the lingering hydrocarbon vapors and fumes from burning dissolve in water and create acid pools? Did the calcium-, silicon-, aluminum-, and magnesium-oxides of pulverized concrete form salts in pools of water? Did the sulfate from the gypsum wall panels also acidify standing water? Did acids work on metal surfaces over months, to alter their appearance?

In the enormity of each rubble pile, with its massive quantity of stored heat, many effects were possible in small quantities, given time to incubate. It is even possible that in some little puddle buried deep in the rubble, warmed for months in an oven-like enclosure of concrete rocks, bathed in an atmosphere of methane, carbon monoxide, carbon dioxide, and perhaps a touch of oxygen, that DNA was formed.
