What follows is a story involving a movie watched by animals. The pacing of the movie to be described might seem like a very odd choice, but it simply mirrors the pacing of human life on the planet. A vivid visual imagination on your part will help to bring the story to life. So, put on your creative cap and let’s dive in!

Picture a small-town movie theater on a street so quiet and unimposing that the surrounding prairie and forest sidle right up to the back of the theater. The marquee advertises a feature film called The Human Saga.

As the afternoon shadows lengthen, a trickle of woodland creatures start to emerge from the forest, mosey up to the theater, pay for tickets, and go in. You notice rabbits, a fox, a group of turkeys, a band of raccoons, some stoats, newts, a skunk (who will be lucky enough to sit next to it?), a hoppy group of frogs, some chittering squirrels, a family of porcupines, a pair of doves, an ancient looking tortoise, a doe and her two fawns, and even a mama bear with cubs. They and many others have all come to absorb a tale of what these humans are all about. It’s a long movie: almost three hours chronicling the almost 3 million years of humans on Earth. But it’s fine: no one is in a big hurry.

The animals amicably settle into their seats, enjoying candy, popcorn, and a hot dog here and there. They’re relaxed, but wide-eyed with excitement for this special treat.

Post-Modernity

April 11, 2024

Post-Modernity

As sketched in the previous post, I believe modernity to be an unsustainable flash that will not persist into future millennia. Uncomfortable with untethered speculation, I have said little about what might come after, but feel I owe something in this vein. Semantically, what follows the modern age must be the post-modern age, right? Except that name is already taken by a rather inane school of thought that may be even worse than modernist thought (it actually does not fundamentally refute modernism anyway, just throws sand into any conversation).

Despite my disdain for post-modernism, I will appropriate the term for what it will likely come to mean in centuries hence (long after people have finally forgotten the silly modern version of post-modernism). I feel better already.

The simplest explanation for why I have not written much on post-modernity is that I don’t feel I have much to say. The range of possibilities is quite large, and I would be a fool to pretend that I—or anyone, really—can paint a credible picture. I’m virtually certain I know how humans will live on the planet tomorrow, fairly sure I could paint an accurate picture for life one year from now, reasonably confident about a decade out, pretty damned fuzzy on a century from now, perhaps a little more clear a millennium into the future (as most of modernity has melted by then), have a decent guess for several million years hence (less likely to still have homo sapiens), and am increasingly certain when the number turns to billions of years (complex life on Earth extinguished). For me, the hardest part is the century scale: the messy, chaotic transition likely characterized by de-industrial scavenging.

Unsustainable Goose Chases

Unsustainable Goose Chases

As we look toward the uncertain future, it may occur to some among us that we’ll need energy on Mars. How are we going to get it? Presumably Mars has no fossil fuels—although on the plus side its atmosphere is already 95% CO₂, compared to Earth’s 0.04%, so they’re likely to be less uptight about carbon emissions on the red planet.

At this point, we could launch into an extensive discussion, full of quantitative detail and analysis about the solar potential: insolation, materials availability, dust storm mitigation, and on and on. But the real answer to how we will get energy on Mars is probably: we won’t. We’re extremely unlikely to set up a permanent presence on Mars, if humans ever even go there at all. So the exercise would be of questionable value.

I feel similarly about discussions of full-scale renewable energy and associated storage and grid shenanigans. How will we rise to the challenge to keep modernity powered into the future? In all likelihood, we won’t. Besides the misdirection of “inexhaustible flows,” keeping modernity powered by any means looks like game-over for ecological health, and therefore humans, if pursued at all costs. So, enough with the fantasy schemes.

Why so bold? Glad you asked.

Past posts of mine have dealt with the question of what sustainability means, and associated timescales:

Ultimate Success: thinking 10,000 years ahead, what’s still possible?
Can Modernity Last?: an attempt to synthesize why continuance is not in the cards
Sustainable Timescales: the relevant scope is that of biological evolution
Inexhaustible Flows: the dead end of materials-hungry “renewable” energy technology

Additionally, The Simple Story of Civilization frames the current epoch as so mind-numbingly new and rapid that it boggles the mind how we could ever think of modernity as a normal time that might have staying power, rather than a fireworks show. It’s only because that’s all our short lives have shown us.

Putting Science in its Place

Putting Science in its Place

Photo by Noam R

Although I might be described as a dyed-in-the-wool scientist, I’m about to say some things that are critical of science, which may be upsetting to some. It’s like those warnings on a movie or show: strong language, nudity, smoking, badmouthing science. So, before I lay into it, let me express some appreciation for what science does remarkably well.

Science exemplifies careful observation—isolating confounding factors to focus on a particular interaction.
Science follows a method that suppresses personal attachment to an idea: nature becomes the arbiter of truth.
When it comes to elementary particles and fundamental physics, one can hardly do any better; although even an atomic nucleus is complex enough to defy exact treatment.
Science advances by trying to tear itself apart, so that surviving notions are very strong.
Because of science, we have a decent outline of how cosmology, evolution, and biophysical systems work.

It has its place.

But the very thing that makes science powerful is also its biggest weakness. It relentlessly pushes wrinkles aside, smoothing its zone of interest to the least complex system one can obtain for study. This is ideal when wanting to observe a Bose-Einstein condensate in isolation, or the genetic mechanism for producing a certain protein. Science also tends to dissect a problem (or literal critter) into the smallest, disembodied pieces—which then have trouble relating back to the whole integration of relationships between pieces. Other “ways of knowing” attempt to grapple with the whole, accepting it as it is and not applying reductionist tools.

Limits of Science

In promoting the cut and dried, dissected, abstracted, tidy realm of science, we can lose the ability to celebrate the wonder, mystery, and awe of complexity and relationship that defy simple frameworks. The artificial, rectilinear, ordered, Cartesian world we construct around ourselves alienates us from more durable but messy realities…

The Simple Story of Civilization

December 20, 2022

The Simple Story of Civilization

The stories we fashion about ourselves are heavily influenced by our short life spans during an age of unprecedented complexity. We humans, it would seem, are unfathomably complicated creatures who defy simple “just-so” characterizations. Animals, or humans tens of thousands of years ago are fair game for simple stories, but not so for transcendent modern humans.

Two major problems I have with this attitude are that 1) we are animals, and 2) we have exactly the same hardware (albeit with slightly smaller brains) as we had 100,000 years ago.

So allow me to pull back from our present age of baffling complexity to outline a simple story covering the broad sweep of the human saga. The result may be a little startling, and, for a number of readers, sure to be rejected by cultural antibodies as “not applicable” (see also my views of our civilization as a cult).

Story Timeline

In order to make comprehensible the vast tract of human time on this planet—itself 5,000 times shorter than the age of the universe—I will compare the 2.5–3 million year presence of humans (genus Homo) on Earth to a 75 year human lifespan: a span that we can grasp intuitively. On this scale, we get the following analogous periods:

First 70 years: various species of humans evolve and coexist (sustainably) on the planet;
Last 5 years: the age of Homo Sapiens (about 200,000 yr; mostly sustainably);
Last 15 weeks: the age of civilization (agriculture; then cities) (10,000 yr);
Last 4 days: the age of science (400 yr);
Last 36 hours: the age of fossil fuels (150 yr of increasingly significant use);
Last 12 hours: the age of rapid global ecological devastation (50 yr).

On this lifetime scale, agriculture is a recent, unexpected hobby we picked up, and one that is still pretty new to us in the scheme of things…

Finite Feeding Frenzy

Finite Feeding Frenzy

Image by ariesjay castillo from Pixabay

You may be aware that our food industry is heavily dependent on fossil fuels, to the point that it takes about 10 kcal of energy input to deliver 1 kcal of consumed food. The enormous energy multiplier is due to extensively mechanized plowing, harvesting, processing, and delivery of food; fossil-fueled fertilization (via methane feedstock); refrigeration and preparation; then of course food waste. In olden times, when all agricultural energy came from muscle power that needed to be fed, the system would collapse (i.e., starve and fail) if energy inputs exceeded energy ingested.

Some have phrased our current practice as “eating fossil fuels,” and in fact a 2006 book by Dale Allen Pfeiffer had this title. So what? More power to us—literally.

The problem, people, is that fossil fuels are finite. We have already consumed a fair fraction (roughly half?) of the accessible allotment. And before concluding that we therefore have a century or so before needing to worry about the consequences, realize that the inflection point happens around the halfway mark, wherein decreasing ease of access tends to result in ever-decreasing output rates in the second-half of the resource. We see this behavior in individual oil fields and in regional (country-scale) aggregations. The low-hanging fruit is taken first, sensibly, so that what’s left is more stubborn.

Because human population has been substantially boosted by fossil fuel input, we have put ourselves into a vulnerable position. What happens when fossil fuels begin to give out on us?

It’s been a while since I did any, you know, math for this blog, as I seem to be living my own worst nightmare and turning into an armchair philosopher (oh the shame). In this post, I return to something closer to math..

The Cult of Civilization

The Cult of Civilization

From Pixabay/KELLEPICS

I recently watched a Netflix documentary series about fundamentalist Mormons, exposing along the way a number of beliefs that seem bizarre from the outside, but that are accepted as perfectly normal within their insular community. Though the term “cult” is not used in the series, it is hard not to see the sect in this light. It would be nearly impossible to convince any one of its members that they are deeply in error, in part because doing so threatens the salvation that has been dangled in front of them. If they are pure enough in their faith, resisting external evils that try to knock them off the one true course, eternity is theirs. In today’s world, one need not look far to find other groups whose beliefs are at once bonkers and seemingly immune to attack.

Hearing the perspectives of ex-members of these cults never fails to be fascinating, providing a window into how they could have swallowed all the lies and goofy stories. Also important to know: it is possible to escape, and to suddenly see the magnitude of the deception. Once out, there’s no going back.

Cult beliefs look insane from the outside, so why don’t its adherents detect the lunacy? Why is it so hard to convince them of their folly? One possible answer—as a tangent—is that cults offer a deeply satisfying sense of identity, belonging, and (seemingly) unconditional acceptance/support within its community that we have otherwise lost in today’s society, but that in times past were central offerings of tribal life to which humans are intimately adapted. It is remarkable how quickly tribal cohesion instincts of mutual help resurface as soon as core elements of civilization (provision of food, water, electricity, for instance) fail in a natural disaster. We’ve still got it, underneath the veneer.

Death by Hockey Sticks

Death by Hockey Sticks

You may be familiar with the term “hockey stick curve,” used describe a trend that has been flat/stable for a very long time, but shoots up at the end of the series in dramatic fashion, resembling the shape of a hockey stick. Hockey can be a violent sport, and it’s easy to get hurt by even one well-aimed swing. Today’s world is being battered from all sides by countless hockey sticks. Mostly, they seem to be targeting Earth’s critters, who are getting bludgeoned unsparingly. But in the end, we’re only harming ourselves.

This post is structured as a gauntlet of hockey stick curves that may leave the reader feeling a bit bruised. Depending on what’s being plotted, many of the graphs shoot up like an exponential, but a few are careening downwards. A theme emerges: the “bads” go up, and the “goods” go down—and not by coincidence.

People and Money

We’ll start simply. Human population looks like a hockey stick curve. This is not a surprise to anyone. The fact is greeted with a range of reactions from joy to despair, but mostly simple acceptance. Whatever your disposition, here’s what it looks like.

Human Population

All the plots in this post will share the same time axis, from the year 1000 to 2200—even for those lacking information across the whole span. The point will be to emphasize the anomalous nature of recent history: what I call the fireworks show. Maybe it would be more fair to use a 10,000 year span (civilization), or 200,000 for modern homo sapiens, or even 3 million years for the entire human saga. On such scales, the present era loses its graceful curve and looks rather more like a sudden brick wall.

My Brainwashing

December 21, 2021

My Brainwashing

From Pixabay/Tumisu.

People rarely recognize or admit that they have been brainwashed. Perhaps the term brainwashed is too extreme, in which case manipulated or fooled may be substituted.

An insightful quote from Mark Twain says:

It is easier to fool people than it is to convince them that they have been fooled.

What often happens, in fact, is that people on opposite sides of an issue suspect (or are convinced) that the other side has been brainwashed. Sometimes one side is more justified in the charge than the other, in which case the brainwashed victims effectively assert a sort of projected symmetry that rings false.

Bi-directional allegations of brainwashing show up in the context of COVID: masks provide a clear means of identifying either those (masked individuals) who have been fooled into controlled submission to believe that the pandemic is real and deadly vs. those (unmasked fighters for freedom) who have been sadly misled to think it’s all a hoax and in so doing endanger us all. Each side may feel anger or pity toward the other. Climate change is similar: its denial has become an article of faith for the brainwashed non-believers, who accuse the gullible believers of being brainwashed by self-serving scientists vying for funding, power, or something (cake, maybe?).

To either side, it seems inconceivable that someone could deny the truths that are so obvious to them. For me, an uptick in total deaths closely matching reports of COVID deaths is pretty convincing, and it is hard for me to make out why anyone in power would want to wreck the economy and could somehow convince countries around the world to overlook a competitive advantage and follow suit…

Caught Up in Complexity

Caught Up in Complexity

From analogicus, via Pixabay

Readers of this blog will know that I have come to some big-picture conclusions about success and failure that are unsettling. I don’t like them myself. Not only do they create an inner sadness about where I think the human endeavor is heading, but they result in a sort of isolation that I would rather not suffer—introvert though I am. Among other academics at my institution, it is rare for me to find kindred spirits, even among groups self-selected to care about environmental issues. Most don’t seem to see very far beyond climate change in the lineup of existential threats, increasingly focusing on inequities within the human population that stem from climate and environmental disturbances. I am glad that climate change awareness is high (a genuine threat), but even if climate change had never arisen, I think we would still be in grave trouble from the more fundamental flaws in our explosive approach to living on Earth.

This is a large part of the impetus behind PLAN, which I announced in the last post. Already, I am gratified that people joining the network from vastly different fields and experiences have formed similar conclusions at the highest level. So I’m not crazy, unless we all are. In any case, I am less lonely. [I will say that crazy is usually easy to spot in conversation: a little too insistent/enthusiastic/one-track. The PLAN folks feel really solid, broad, and even perhaps subdued to me: not the type you want to back away from at a party.]

But I still try to understand why so few of my colleagues have reached similar conclusions. The easy answer is that I’m just plain wrong…

Credibility from Apparent Hypocrisy

Credibility from Apparent Hypocrisy

Flip the script! Image by Gerhard G. from Pixabay

Purveyors of unpopular messages are often scrutinized for any inconsistent, seemingly hypocritical behavior that might give lie to their preachings and be used to discredit the unwelcome perspective. A famous example is Al Gore’s heavy air travel schedule to spread the word and take action against climate change, resulting in an enormous CO₂ footprint. If we all behaved that way, the very problem at hand would be substantially exacerbated.

Such accusations either knowingly or pathetically miss the obvious point that the net effect of Al Gore’s efforts may be positive owing to the simple idea of a lever: a little expenditure here can counteract vast expenditures elsewhere for an overall gain on the problem. For many, the glaring superficial contradiction is enough ammunition to discredit the entire enterprise.

But identifying possible hypocrisy in those who warn of future perils, as I have done, has a dark edge: if even those cognizant individuals cannot get away from behaviors they know to be damaging, doesn’t that only amplify the severity of the warning?

This is the part where I confess various behaviors that would seem to be inconsistent with my writings. It is true that my energy and resource footprints are far below the U.S. average—in electricity, methane, gasoline, food, and consumerism. I re-evaluated my footprint in comparison to average Americans in Chapter 20 of my textbook, confirming a factor-of-several reduction in most categories.

So I can perhaps justify some sense of credibility in putting my money where my mouth is. Or more accurately, I refrain from putting money places in accordance to what comes out of my mouth (and fingers). It can be hard to separate ecological responsibility from just being a cheapskate.

To What End?

To What End?

Image by naturfreund_pics from Pixabay

Recent reflections on the long-term trajectory of the human enterprise have somewhat transformed the way I look at most activities. Specifically, I refer to the dual realizations that on 10,000 year timescales ultimate success is effectively synonymous with true sustainability, and that the human race stands in blatant breach of contract with evolution and ecosystem parameters—fueled by a mad grab of one-time finite resources. The net effect is that most human activities today promote ultimate failure rather than ultimate success.

As such, when evaluating a proposed or ongoing effort, I ask myself the question:

To what end?

This post will examine some of the activities of current society, and evaluate how much sense they make in the context of a post-party future.

I’ve had enough of the human tendency to “follow our noses” based on near-term advantages at the disastrous expense of long-term success. Humans have acquired the power to radically change the world. Great power should ideally be wielded only by those capable of great responsibility. But we cheated somehow, and grabbed power because we could, without first demonstrating responsibility. No higher or wiser authority was present to tell us not to.

The result is even worse than doing things willy-nilly, like an unconstrained firehose. Because even that firehose will sometimes by random chance throw water on the fire. Our actions are more systematically directed at accelerating destruction by eroding ecosystems that ultimately constitute our own life support on this planet.

A core problem is that most people lack the tools of math and science to inform thought, relying instead on history and experience as their bedrock. Even those adept at math and science generally have not directed their skills toward critical inspection of society’s prevailing narratives…

You Call this Progress?

You Call this Progress?

$From collection of futuristic ideas.$

One of the prevailing narratives of our time is that we are innovating our way into the future at break-neck speed. It’s just dizzying how quickly the world around us is changing. Technology is this juggernaut that gets ever bigger, ever faster, and all we need to do is hold on for the wild ride into the infinitely cool. Problems get solved faster than we can blink.

But I’m going to claim that this is an old, outdated narrative. I think we have a tendency to latch onto a story of humanity that we find appealing or flattering, and stick with it long past its expiration date. Many readers at this point, in fact, may think that it’s sheer lunacy for me to challenge such an obvious truth about the world we live in. Perhaps this will encourage said souls to read on—eager to witness a spectacular failure as I attempt to pull off this seemingly impossible stunt.

The (slightly overstated) claim is that no major new inventions have come to bear in my 45-year lifespan. The 45 years prior, however, were chock-full of monumental breakthroughs.

A Tale of Three Times

Before diving into the defense of my bold claim, let’s set the stage with a thought experiment about three equally-separated times, centered around 1950. Obviously we will consider the modern epoch—2015. The symmetric start would then be 1885, resulting in 65-year interval comparisons: roughly a human lifetime.

So imagine magically transporting a person through time from 1885 into 1950—as if by a long sleep—and also popping a 1950 inhabitant into today’s world. What an excellent adventure! Which one has a more difficult time making sense of the updated world around them? Which one sees more “magic,” and which one has more familiar points of reference? The answer is obvious, and is essentially my entire point.
