Yes, believe it or not, I haven't actually forgotten about this blog or this series of posts.
In tenth grade I took a one-semester Science Fiction Literature/Composition class, from which I only remember one piece of knowledge: toward the end of a traditional fantasy quest narrative, there is always a point called the Abyss, where it appears that the villain is about to win and the hero is helpless to prevent it. This is immediately followed by some kind of unexpected reversal that allows the hero to save the day.
The standard activist narrative on the climate crisis works the same way. "Greenhouse emissions are increasing faster than ever, and we only have a few years before it will be impossible to restore the climate to a healthy state -- but if we all get together and demand drastic action from world leaders, we can still save the world!" And I've bought into this narrative for years, dismissing or forgetting about the numerous challenges to its plausibility, because the alternative was to admit that within my lifetime, civilization will almost certainly slide into a new dark age.
Paul Gilding's first thesis in The Great Disruption is that the crash is inevitable because we won't develop the will to prevent it until it's too late. But this points the way to a deeper truth: even if we had the will, we probably can't prevent the crash, no matter how hard we try. (Contrary to the title of this post, I'm not going to spend time here trying to figure out what Gilding said that forced me to acknowledge that truth.)
One of the earliest challenges to the activist narrative that I've successfully avoided thinking about was a set of three graphs in the book Affluenza: the All-Consuming Epidemic, which was one of the readings for my Intro to Environmental Analysis class in college. In reverse order, the graphs are "The Carbon Dioxide Spike" (p. 161), "The Consumption Spike" (p. 154), and "The Extinction Spike" (p. 92). Each of these graphs shows a classic hockey-stick exponential growth curve, demonstrating clearly that these trends are accelerating beyond all hope of control. Similar graphs could be drawn for topsoil loss, falling water tables, pollution of surface water, deforestation, and ocean acidification, among others. This means that our food and water supplies can't be maintained at current levels much longer, and even the rate of global oxygen production by plants and algae is under threat.
One common reaction to all this rapid change is to say, "Look how powerful we've become! Humans can now change natural systems on a global scale! Surely we can use that power to bring those systems back to healthy norms and stabilize them there!"
But that's crazy. Imagine that half a second ago, you accidentally cut open a major vein on your arm with a knife that you made. Does the power of that knife to release massive quantities of your blood mean that, even with no real first-aid training, you'll be able to stop the bleeding and sew up the wound within the next half-second? That's how absurd it is to claim that our current technological capabilities are up to the task of saving us from the destruction we've wrought in the few decades before it overwhelms and destroys our current civilization.
If it were only greenhouse emissions that we had to worry about, we might stand a chance. Something like Gilding's "One-Degree War Plan," described in chapter 10 of The Great Disruption, might suffice to bring carbon-dioxide levels back down below 350 parts per million by century's end. And to be fair, part of that plan involves sequestering carbon in soil and biomass, which would also help rebuild topsoil and forest cover. But given the enormous complexity of Earth's systems, there's not really much chance that we could figure out how to calibrate our actions carefully enough to get close to the climate we want and then stabilize there, and there's a very high likelihood that the massive spike in construction of energy infrastructure and so-called "reversible geoengineering actions" will cause other problems to worsen even faster.
Now, I just attended my fourth Bioneers conference last weekend, and I know what the Bioneers answer would be: "Gaia has the solutions to everything. All we have to do is mimic what natural ecosystems would do to solve these problems."
But there are two fatal problems with this answer. One is that Gaia works slowly; for instance, it certainly took a whole lot more than one century for life to recover from the asteroid impact that killed the dinosaurs.
The other problem is that Gaia doesn't actually care about keeping the climate as stable as our current civilization needs it to be (and the same likely applies to the other factors I listed). If you look at a graph of temperature over hundreds of thousands of years, you see that the current interglacial period, the Holocene, in which temperature fluctuations stayed within a narrow range for ten thousand years, is highly unusual. The last several interglacials have been far less stable, and then of course there are the Ice Ages, which last much longer, and which Gaia has clearly done nothing to prevent. From Gaia's perspective, the "healthy norm" for climate is anything that doesn't totally freeze the oceans or turn all the land to desert.
So, as 350.org founder Bill McKibben pointed out in his book Eaarth: Making a Life on a Tough New Planet (a stark challenge to the activist narrative espoused by 350.org itself), we have a clear task ahead of us: learn to be resilient to changes in Earth's systems vastly larger than any we've seen in the history of civilization. Science and technology have produced many tools that could be useful in this regard, but to keep those tools, we'll have to start by overhauling our whole manufacturing infrastructure to cope with these massive disruptions, while doing what we can to slow down all those accelerating trends to give ourselves more time. And we'll need to store our knowledge in a durable form that even crazed combatants in some future war won't be able to destroy, so that any tools we lose can be rebuilt again later.
Eventually we might assemble a set of resilient strategies powerful enough to maintain something like our present quality of life despite the endless string of crises. Perhaps then we could think about launching a second Space Age, but that won't be possible until long after I die. Thus, for the first time in my life, I've been forced to admit that we won't even make any real progress toward the future I dream of within my lifetime, and my only consolation is that I might be able to help make that world more likely to happen in some distant future.
In short, our present moment, dark as it may seem, is not the Abyss in our quest story. It's actually more like the moment just after the introduction, when the protagonists are forced from their comfortable homes and into a long, hard journey through great perils. But in our case, the perils are real and we have no narrative structures to defend us from a tragic ending.
Good luck then, to all of us. We're going to need it.
