Can Modernity Last?

Do the Math started out with a pair of posts about limits to growth. Galactic-Scale Energy pointed out the nonsense that results from continued growth in energy use, and Can Economic Growth Last? turned to the economic implications of stalled physical growth. This combination of topics later appeared in a dinner conversation between myself and an economist. The same pairing also evolved into chapters 1 and 2 of the textbook I wrote in 2021. And if that wasn’t enough, I published a paper in Nature Physics called Limits to Economic Growth based on the same theme. When I do podcast interviews, the hosts often want to step through this (powerful) logic.

Perhaps the result has me sounding like a broken record. It feels to me like the song “Free Bird” by Lynyrd Skynyrd. Fans will not allow the band to perform a concert without playing this classic hit. There’d be riots. I’ve had a lot to say following those two posts in 2011, and have especially taken a profound turn in the last few years. But the point remains central to our modern predicament, and until we all have it firmly planted in our heads that growth is a very temporary phase that must end, I guess I could do worse than repeating myself to new audiences—and to veterans holding up lighters.

In this post, I echo the bedrock question of whether economic growth can last with the question of whether modernity can last (see the previous post for definition and possible inevitability). Okay, nothing lasts. The whole universe is only 13.8 billion years old. The sun and the earth are only about 4.5 billion years old, and will be around in recognizable form for a comparable time into the future. Species typically hang around for millions of years. Homo sapiens is a few hundred-thousand years old. Depending on definitions, modernity has been around for at least a century or as long as 10,000 years—brief in either case, in the scheme of things. Nothing is forever, but how long might modernity last?

Whether modernity can last is perhaps a more important question than whether growth can last. The fact that growth can’t last is shocking enough for many. But it still allows mental space for maintaining our current way of life—just no longer growing. But is that even possible? I can’t be as confident in my answer as I am for growth, since the question of growth comes down to incontrovertible concepts and, well, math. Still, I strongly suspect the answer to this new question is “no” as well, and in this post I’ll expound on my misgivings.

[Note: I had another post in 2021 enumerating reasons to worry about collapse, which is a relevant but—I would say—less enlightened precursor to this piece. Since then, I have become aware of the important role of human supremacy, the materials difficulties associated with renewable energy, the crushing numbers on loss of biodiversity, and have released my anxious grasp on modernity—having better appreciated the more-than-human world and our role within the greater community of life.]

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.

Growth Is Our Old Yeller

Posted on by

Poster for the 1957 film Old Yeller

Growth has been our close companion for centuries, and we love it to pieces. It makes politicians swoon, economists dance, investors giggle, and community planners smile.

The only problem is that this friend is about to turn into our greatest enemy.  Pursuit of growth—in money and resource exploitation—has a flip side on Earth’s ecosystems.  Up until now, we mostly saw the good side of growth: conveniences, technology, health care, security.  Becoming apparent is the toll this misguided focus is taking on our irreplaceable home.  No amount of money (all the king’s horses and all the king’s men) can restore lost species and destroyed ecosystems.  So maybe money is a bad metric for what really matters, yeah?

I have struggled to come up with a good analogy for growth that will help us process what it means.  The best I have come up with (and only recently) is that growth is like Old Yeller.  If you’re not familiar with the 1957 film, it’s a real tear jerker.  I remember bawling in concert with my sister when the amazing dog—dearly loved by the family for getting them out of many a pickle—contracted rabies, became aggressive toward the family, and had to be shot.  That’s right: a kid’s movie ended with the beloved central character being shot dead.  Those were different times.  What you really wanted in a kid’s movie was for your children to emerge wrecked. (I also saw Jaws at age 6 and have been scarred since.)

Growth has likewise been this fantastic friend: all upside, upside, upside.  But the rabid side is beginning to show, and our ultimate success depends on killing it.  There will be tears.  Many will bargain, unable to accept the necessity of ending growth.  But it’s no use.  The physics is clear.

Please use the comment forum to suggest other (better) analogies.  Not straying too far, it may be like raising a lion: awfully adorable as a cub, but ultimately a mortal threat to have in the house.  It’s possible that better analogies can be conjured.

P.S. I wrote this in 24 minutes, so please excuse the shortness and sloppiness.

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.

Ultimate Success

Posted on by

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?

Sir David Nails It

Posted on by
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.

Textbook Debut

Posted on by

Energy Ambitions textbook coverHello, all, and welcome (me) back! After years of radio silence, I am popping back up and have more to say in the coming months as I re-engage on topics relevant to this blog.

The first thing is to announce the launch of a textbook at eScholarship that is free to access electronically (can download PDF), or is available in paperback form for the cost of printing (royalty-free; at Lulu). Over the years, I received a number of encouragements to write a book collecting the ideas and analysis from Do the Math posts. I appreciated the sentiment, but given the substantial effort required to produce something that was already available for free on this site never rose to a high priority in the competition for limited time.
