The Simple Story of Civilization

[Note: This post inspired a podcast interview that traces a similar path.]

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).

A Climate Love Story

From Pixabay (Kranic17/535 images)

The year is 2050. Things are unimaginably better than anyone in 2022 might have predicted. Such turnarounds are not without precedent. After all, the boom time in the 1950s came on the heels of the Great Depression and a crippling world war against ominously dark forces.  From the depths of those hard years, it would have been hard to foresee the glory days around the bend.

In our imagined 2050, climate change has been tamed by a spectacular suite of technological feats: fossil fuels are all but obsolete except in a few backwater places, replaced by an impressive profusion of solar panels, wind turbines, hydroelectric dams, thorium reactors, deep geothermal installations, and a nascent fusion industry on the verge of commercialization. Electric transport handles most domestic needs, while a bounty of biofuels powers air travel and long-haul shipping.

Breakthroughs in battery technology have resulted in large banks of lithium storage everywhere you look to smooth out the irregularities in renewable production. Seasonal-scale storage is around the corner, so that even places like Alaska will be able to satisfy demand year-round based on a massive energy haul from long summer days.

Freed from the constraints of obtaining energy from petro-states, countries are able to source all of their energy needs within their borders and in fact have more available energy than they did when dependent on primitive fossil fuels. Economies are thriving: global trade is more vigorous than it has ever been because energy is cheap and abundant.

Continued revolutions in computing power and device technology has us swimming in cool gadgets—putting something akin to Star Trek tri-corders in our hands, in contrast to the smart phones we fawn over today (mere walkie-talkies by comparison).

Abundant energy has transformed energy-intensive practices of food production and mining, so that everyone’s dietary and material needs are met, finally ameliorating hunger and gross inequity globally. Based on rising standards of living, birth rates are predicted to stabilize by century’s end so that we are on track to cruise toward a stable, peaceful, sated global regime.

In short, we’re total rock stars for having achieved a whole new phase of prosperity and amazingness. Martian colonies? Why not? While we’re fantasizing, let’s throw those in too! So yes, we are on our way to exporting our conquest to the stars and all is as it should be.

Part of me feels really crummy doing this to you. My motivation is not to be mean, really. Rather, I think it is incredibly important that we approach our future prospects realistically and understand fundamental planetary limits. So I’m afraid this is where I pull the rug out from under you. But see, I’m warning you and apologizing in advance rather than gleefully anticipating your bruising fall. Feel free to step off the fantasy on your own, if you have not already done so. Three. Two. One.

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.

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. But believe me, I have tormented myself to try to discover the missing piece and go back to being a happy human bumping along in this race to who-knows-where. It’s not that my unconcerned colleagues have thought more deeply about the issues and can help a rookie out, in my experience.

In this post, I venture some guesses about the disconnect—some of which may even be on target. I will loosely frame the discussion in the context of academia, but much of the logic  also applies beyond this scope. The basic idea is: complexity makes it hard to differentiate between  real and artificial worlds.

Why Worry About Collapse?

Nothing lasts forever.

The first thing I should say is that the word collapse freaks me out. I don’t use it often, for fear of sounding like an unhinged alarmist. Surely, respectable scientists should want nothing to do with it.

The second thing is that I don’t harbor any secret pleasure in imagining catastrophic failure of the human endeavor. It depresses me, frightens me, angers me, frustrates me, confuses me, and makes my wife crabby.

What keeps pulling me back to it—despite my innate repulsion—is not only credible elements of risk that I will get to in this post, but also that I think it’s too important to tolerate our natural tendency to hide from the prospect. Ironically, doing so only raises the odds of that ill fate: mitigation requires direct acknowledgment. Failure to speak openly and honestly about the less-than-remote possibility of collapse is not in our best interest, ultimately.

So let’s grit our teeth and confront the collapse monster. What conditions make it at once likely and off most people’s radars?

It is a heavy lift for one blog post to do a complete job in motivating collapse as a realistic outcome of the human enterprise. Any one argument can be picked at, but the totality should be considered. This is a long post, so buckle up.

In Breach of Contract

Image by Edar from Pixabay

Evolution is like a lengthy job application process. Each new species endures a long and harsh vetting procedure to judge what role it plays in the ecosystem, how prepared it is to deal with lean years, predators, disease, climate variations, and anything that might reasonably be expected to arise even once in a thousand generations. Those species not able to satisfy the impartial judges of nature are voted off the island. It’s a tough crowd.

The successful species—the ones that have held on for many thousands of generations—essentially have signed a contract with nature. The contract is implicitly a “common law” arrangement: if you’ve stayed with us this long, you’re (indifferently) accepted as part of the family.

The terms of the contract are also implicit: as long as you continue to operate within the parameters by which you were judged to be adequate members of the ecosystem, you enjoy the built-in protection of that same ecosystem to continue survival, having carved out a role integrated into the rest by a complex web of interdependencies.

Humans signed our contract with evolution based on a primitive lifestyle that persisted for hundreds of thousands of years. We also inherited clauses from ancestor species, whose capabilities we incrementally altered, thus extending the vetting span to millions of years.

Humans today stand in gross violation of our pact with nature. We are egregiously in breach of contract. Our protections are thereby revoked.

Ultimate Success

What success might look like? Image by Emma Farley from Pixabay.

In early fall 2020, I took a break from intense work on textbook preparation to immerse myself in nature, in the form of a month on the Olympic Peninsula. I spent periods of good weather in the backcountry, and therefore didn’t bother carrying a tent along in my already-too-heavy backpack. Somehow sleep is more precious when there’s some chance of being woken by a (black) bear’s slobbery breath in your face. But for the many dozens of times I’ve slept this way in the wilderness, I have not had a single nighttime bear encounter—being exceedingly careful to keep food smells well away from my sleeping site. Luckily, it would seem that my physical person does not smell like food.

I’m not an adrenaline junkie with a death wish, but exposing myself to some risk at the hands of nature brings a greater appreciation of the relationship between humans and the world of the wild. Being a temporary tourist in nature is not quite the same as fully being a part of nature, but it’s closer than many experience in our human-dominated artificial world.

One of my aims for the trip was to step back from the nitty-gritty focus on margin-notes and glossary items for the textbook and synthesize a broader picture. Being immersed in the wilderness really helped that process. Nature is so grand; so ancient; so indifferent. Nature is wild. Nature is mature.

Humans have embarked on a 10,000 year experiment to separate from nature: to build stores and access “old money” that Earth has banked for eons, providing a recent freedom to largely ignore annual, renewable flows in nature. The last several centuries have accelerated the divorce to an alarming degree. But the question I stumbled upon as my boots navigated rocks and roots on the trail was:

Is the 10,000-year-old human civilization in its infancy, or nearer its end than its beginning?

Earth's Real Treasure

Image by Gordon Johnson from Pixabay

A 2018 paper by  Bar-On, Phillips, and Milo in PNAS contains a fascinating figure (Figure 1) that bears staring at for some time. It shows the dry carbon biomass distribution of various forms of life on Earth. Plants account for 450 Gt (giga-ton; 1012 kg) of mass, while the sum of all animals adds to 2.5 Gt. Humans comprise only 2.4% of animal mass on the planet, but that’s almost ten times as large as wild mammal mass. Add human livestock (outweighing human mass) and wild mammals are only 4% of the human-livestock-mammal trio.

But this post is heading somewhere else: lament about the un-wilding of the planet on your own time (kidding aside, please do!). Let’s start by considering the following question. Which do you think is more valuable: the web of living animals on this planet, or all the gold accessible in the ground? If given a choice to eliminate one and preserve the other, which would you choose? Gold, among Earth’s mineral stocks, is used for this question because it has served as a physically-based monetary standard for many cultures throughout time.

What follows has absurd elements to it, but hopefully in forgivable service of a larger point about the value of life on this planet and in shining a glaring spotlight on current human values.

Sir David Nails It

David Attenborough for A life on Our Planet

This is the TV poster for “David Attenborough: A Life on Our Planet.” (CNS photo/Netflix)

If you have not already watched A Life on Our Planet, serving as a witness statement from Sir David Attenborough, please find a way to do so. During his experience-rich lifetime, Attenborough has had a front row seat to the steady whittling down of nature. Any contemporary nature show will justifiably sound the climate change horn, as A Life on Our Planet does as well. But Sir David digs deeper, as few tend to do, and scoops up the essence of the matter.

I have now watched the show three times. The first instance resonated strongly with recent revelations and writings of my own, and I gladly watched it a second time with my wife. The third time, one hand hovered over the pause button while the other scribbled notes and captured key quotations. This post delivers said quotes and connects them to themes dear to my heart. Note: the quotes in the show are delivered verbally, so any formatting emphasis is my own.

Peak What?

[An updated treatment of some of this material appears in Chapter 8 of the Energy and Human Ambitions on a Finite Planet (free) textbook.]

separating U.S. influence on global oil production

(you’ll see larger later)

I’ve been maintaining “radio silence” for a while—mostly on account of an overflowing plate and several new new hats I wear. All the while, I have received a steady stream of e-mail thanking me for Do the Math, asking if I’m still alive, and if so: what do I make of the changing oil situation? Do I still think peak oil is a thing?

Let’s start with the big picture view.

I was wrong about everything. Oil is not a finite resource: never was and never will be. We will employ new technologies and innovate our way into essentially perpetual fossil energy. We’ve only scratched the surface in exploration: there are giant deposits (countless new Saudi-Arabia-scale fields) yet to be discovered). The shale oil tells us so—and it won’t stop there. Shale first, then slate, marble, granite: just squeeze the frack out of rocks and we’ll get oil. Meanwhile, whole new continents are being discovered, rich with resources. The most recent was hiding behind Australia. And naturally it doesn’t stop there. We have now discovered thousands of planets just a hop away, most of which are likely to contain fossil fuels of their own. So game over for the resource limits crowd, yeah?
