Finite Feeding Frenzy

Posted on by

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. It’s illustrative rather than quantitative, but helps frame the peril we have put ourselves into in a low-effort sort of way.

The Cult of Civilization

Posted on by

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.

Leaving that for another time, let me now condemn myself in the court of civil opinion by making the charge that most people on Earth are members of a dangerous cult whose central beliefs seem every bit as bizarre to one who has escaped the thought prison, but that are seldom questioned and even fiercely defended. This post offers ten heretical statements that seem obvious to me, but tend to produce emotionally charged reactions by members of the cult of civilization. Watch yourself, now. Continue reading →

A Climate Love Story

Posted on by

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.

The Ride of Our Lives

How much time do we spend fretting over the course we take as a human species? Granted, perhaps too few are focused on ultimate success, which I define as long-term sustainable living as a subordinate partner to all of life on Planet Earth. Even for those who do concern themselves with the intermediate and far future, attention tends to focus on what adjustments we can make to steer a safer course. Yet, when have we ever truly steered our path as a species? Are we actually in control at all? I’ll argue that we’ve never really been in the driver’s seat on the decisions that have mattered most. Our path has been more like an amusement park ride equipped with an ornamental steering wheel, giving the adorable tykes an intoxicating but illusory sense of control.

The central idea is that any development conferring a short-term competitive advantage will come to dominate the landscape, so that failure to adopt it means losing the race and dropping out of the future. It’s a meta-evolution selecting for something other than our best interests. And it’s winning, as it must.

Shedding our Fossil Fuel Suit

Posted on by

Fossil fuels have leveraged human power and ingenuity to a remarkable degree. Their discovery and accelerating utilization utterly transformed lifestyles, achievements, and even how we perceive ourselves as a species.

Yet, one thing we know for certain about fossil fuels is that they are a finite resource on this planet—slowly developed in select locations over hundreds of millions of years and being used about a million times faster than the rate of production. We know that we have already consumed a sizable fraction of the initial inheritance: perhaps now halfway through the irreplaceable allotment of oil. So we know that this phase of the human adventure is a temporary one.

The quintessential graphic for conveying this idea is one I have used many times, because I believe it is the most important plot modern humans could possibly absorb. Human energy use has shot up in the last 150 years, and in the context of fossil fuels will plummet on a similar timescale, leaving—what, exactly?

fossil fuel usage is recent, fast, and will be over soon

The fossil fuel energy explosion that powers our current fireworks show is a momentary phenomenon that will be over in a historically short time.

Over timescales relevant to civilization (which began 10,000 years ago with agriculture and cities), plots of almost anything relating to human activity look like hockey sticks: population, agricultural output, industrial output, mined materials, deforestation, species extinctions, and so on [see this later post]. Many of these certainly correlate to population growth, but the per capita impacts also have shot up, compounding the human footprint to a frightening degree. At this point, humans and their livestock account for 96% of mammal mass on the planet, leaving a mere 4% for all wild animals (half of this from massive whales and other marine mammals). It’s not just a footprint any more: it’s a boot on the throat of the planet, leaving non-human life gasping and silently begging for even a little mercy. Is anybody getting video of this?

Almost all of this explosive impact can be traced to fossil fuels, which I have started visualizing as a suit donned by humans that has given us literal superpowers. What would we be without our fancy suit?

Caught Up in Complexity

Posted on by

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?

Posted on by

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.

To What End?

Posted on by

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.

In Breach of Contract

Posted on by

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.
