Sorry about the long silence, but I’ve been researching a new story setting, just for fun.

The news is that I’ve got another guest blog up on Charlie Stross’ Antipope. It’s about the possible consequences of Mark Jacobson’s plan to power the US using only renewable electricity.

And now for something completely different, what I’m doing on my summer “vacation.”

American Byzantium, an alt-future

Actually, as a thought experiment, I started playing with what California might look like in the High Altithermal, from about 2100 CE to about 3600 CE.  It’s more complicated than I’d initially thought, of course.  If it’s something you’re interested in, contribute your ideas in the comments, and I’ll work them (or some of them, anyway) into the next blog post or two.

In the meantime, here’s a future that I’m pretty sure won’t happen.  The idea is that US history will parallel Roman history, with the eastern US playing the western Roman empire, Washington DC playing Rome, and the western US playing the Eastern Roman Empire.

I gave an overview of the transformation of the Roman empire in Hot Earth Dreams in Chapter 17, and the idea is that the Roman Empire proved ungovernably large, and Rome proved ungovernably corrupt, so Constantine moved the seat of power to Constantinople around 330 CE, and his sons split the empire into the Eastern and Western empires.  The western empire collapsed in 476 CE, while the Eastern empire transformed over time into the Byzantine empire and survived until 1453 CE.

Following this analogy over-faithfully, the US capitol moves west as the (south)eastern US is devastated by increasing heat, black flag weather, rising seas, and the collapse of civilization in the face of such disasters.  In this case, they move the capitol ultimately to perhaps Portland, although someone might argue that Fairbanks or somewhere near Anchorage might be a better site.  Washington DC gradually falls into ruin before being swallowed by the Atlantic, and what’s left of American culture shifts west, while statelets in the east fight over who gets to rebuild America.

Culturally, Byzantium wasn’t Rome.  They were Christian, spoke Greek, and practiced Medieval-style warfare.  In this alt-future, we can mimic the same shift by, um, let’s see, having western Americans speaking Spanish or Spanglish (except when reading law and science, which would be in English), and mimicking the feudal social structure with something like an unholy mashup of drug cartel culture and west coast capitalism, with CEOs instead of counts and Cartel leaders instead of dukes.  Since a lot of feudalism came from Rome adapting the culture of the migrating tribes of Celts and Germans, this isn’t entirely as stupid as it sounds.  “Celts” as a group were probably as polyglot as today’s Latinos are, and had to experience similar levels of prejudice within the Roman Empire (for example, having red hair in Rome was probably akin to being black in America).  Note that I’m not implying that today’s Latinos are in any way barbarians, nor that the drug cartels are the best that Latino culture has to offer.  I’m more thinking of what is a Latino analogy to the old Celtic and Germanic warbands.  If you think that Latino culture has something better and more resilient to give to the future, let me know in the comments.

In any case, if the USA broke down somewhere in the 22nd century, then the Western American Empire (“Alta Mexica?”) might last for another thousand years.

Now I don’t think the US will replay Rome, so this scenario is presented as a bit of a spoof of the idea that US history will mirror the history of the Roman Empire.  It looks like it could, just maybe, work, so if anyone wants to use it in a story, please be my guest.   If you’ve got anything you want to contribute (comments or ideas), please share those too.

Now that I’ve got that scenario out of my brain, in the next blog entry (or three) I’ll look at California in the High Altithermal, Hot Earth Dreams style, with temperatures spiking over the next ~300 years, sea levels rising over the next ~1600 years, civilization and populations crashing, and everything migrating.  How long might the US hold together, will it fragment, what happens with Mexico, and all that are questions that need to be answered, along with lifeways, transportation, where the settlements are, and so forth.  If you’ve got ideas, put them in the comments, and let’s see what we can come up with.


White Men in the Jungle, and other Cli-Fi issues

Perhaps I’m borrowing trouble here, but one thing I started thinking about is how much stereotypes and standard tropes underpin science fiction and especially fantasy. Even though educated people know about the Medieval Warm Period, so much fantasy contains the equivalent of Game of Thrones’ “Winter is coming.” Yes, this is great escapism in the middle of summer, but still, there are a huge number of tropes that show up when dealing with fantasy: medieval, Europe, wintry, or mysterious, oriental, and so forth and so on. You’ve seen them, you know them, and writers too often depend on you knowing them.

Yes, I can think of more than a few books that break tropes, but equally, I run into people whose take on writing is conditioned by the metaphors and tropes conjured by words, and this makes communication difficult. One example was when I talked to a writer (with a strong humanities background) online, about how I, as an ecologist probably wouldn’t name plants that were growing in a vacant lot in southern California as a way to describe the scene. Why not? came the question. Well, I replied, because I suspected that the names wouldn’t paint the scene for anyone who didn’t know the plants already. This was scoffed at. Okay, I wrote, the plants I’m thinking of are black mustard and ripgut brome. Oh, those are so evocative of doom, decay, and violence. Perfect for a vacant lot in Southern California. Well, I replied, that’s exactly my point. You just misled yourself, I replied, and you have no idea of what I was actually trying to describe…The conversation deteriorated from there. Yes, this conversation has been changed somewhat, because I want to use it as an illustration, rather than to embarrass someone. The miscommunication is the point.

The idea I’m chewing on, the trouble I’m borrowing, is how to deal with climate change in fiction, “cli-fi” if you want a newish shorthand. If you’re writing about a climate changed world and thinking like an ecologist, it makes perfect sense to talk about a tribe of white-skinned people living in a jungle, because tropical forests are predicted to grow north into modern Oregon if we go in for severe climate change. If you’re not thinking metaphorically (would that be trope-ically?), it’s perfectly reasonable to talk about the descendants of today’s Portland hipsters living a barbarian lifestyle in the coast ranges, in a dense forest of bamboo, briars, kudzu, and naturalized street trees, hunting feral pigs and settling all too often for grasshoppers instead.

The problem is, if someone who reads metaphorically sees this, all sorts of problems jump out. Is it cultural appropriation or imperialism to put white men in jungles? Or to have them happily eat the foods of other cultures, like grasshoppers, which are edgy and taboo in today’s America? Or to work with bamboo? I don’t know. But jungles bring all sorts of cultural baggage and expected tropes along with them. Any place does. That’s why fantasy castles are set so often in fantasy Europe, rather than in the fantasy Amazon, fantasy Congo, or fantasy Zomia. Especially if the characters are white.

Climate change violates these tropes, moving climates, and eventually the plants and animals they support, to different places than they occur in now. That’s why I’m interested in cli-fi, really, because a climate-changed future gives you a huge new palette of possible realities to explore. The jungles of Cascadia may be a real place in 300 years.

The shortcoming of this new palette is that it violates expectations, and I suspect this is one reason why people tend to think of post-apocalyptic stories as set in a ruined version of today’s world, rather than in something much stranger. It’s easier to think of such stereotypes, rather than to confront how strange the world could get.

And it does get more complicated. If you want to write a story set, say, 10,000 years in the future, humans probably won’t have the races or ethnicities we have now. And there’s a whole other set of expectations, stereotypes, and tropes associated with race, especially in America and most especially now. If you want to write a story set in the truly deep future, you can legitimately jettison today’s races and start over. However, how do you write the resulting story without it being seen as a commentary on today’s racial politics? I have no idea. Maybe you don’t. Thing is, it’s unrealistic to assume that today’s racial, ethnic, even gender identities have any sort of permanency. Is talking about this a reflection on today’s racial politics, or just some naive white dude (that would be me), trying to think about what the future might hold? It can be read both ways.

And so it goes. I don’t have any answers, only questions. Authors don’t get complete control over what people read into their work, and readers bring a wide variety of preconceptions with them to any work. Still, if you’re going to play outside established tropes, I don’t think it’s overly paranoid to at least think about how things can be misinterpreted, and possibly to take some steps to head off the worst problems.

Or perhaps I’m just borrowing trouble where none exists. What do you think?

That brief window

Well, the book manuscript is done, and I’ve got some beta readers going over it while I figure out the strange world of non-fiction publishing. As I understand it, one not supposed to write a non-fiction book on spec, but rather to have a contract to write the book based on how well you can convince the publisher it will sell, based on your audience. And simultaneous self-publishing is a thing too, apparently. Interesting business, especially when I write a book of 100% speculation about a climate-changed Earth, and it’s called non-fiction.

So I have time to blog more regularly.

One of the things I’ve increasingly noticed is how bad we are with big numbers, and dealing with big numbers turned out to be a central feature of the book. In general, when we look at phrases like a few years, or a few decades, or a few centuries, or a few millennia, or a few thousand years, or a few million years, we fixate on the “few” and ignore whatever comes after that. As a result, we get weird phrases like the Great Oxygenation Event, which took a few billion years back when the Earth switched from an anaerobic atmosphere to aerobic one. It doesn’t sound like much, until you realize that animals have been on land less than 500,000,000 years, or less than a quarter of a billion years. The Primitive Animals Invade the Land Event will end with the expanding sun making such life impossible on Earth long before our little event matches the length of the Great Oxygenation Event, yet people some people still think that the Earth was oxygenated very suddenly, rather than incredibly gradually. All that happened was that people ignored all the zeroes, called a process an event, and confused themselves and their audience.

This applies to human history as well. If we take the Omo 1 skull as the oldest modern human, we’ve got at least 195,000 years of history to our species already.

We’re young compared to most species, but we’ve still got a lot of history, and most of it is lost. Our documented history is about the last 5,000 years, and the archaeological becomes fragmentary shortly thereafter. In other words, thanks to writing, we’ve got partial access to about 1% of our apparent history as a species. The conventional interpretation of this is that humans were basically boring for the first 99% of our history, then something changed, and we took off like gypsy moths, expanding into this outbreak of humanity we call civilization. Prior to that, we were peaceable-ish hunter gatherers living in harmony with nature.

What changed? The more I read, the more I tend to agree with the archaeologist Brian Fagan. In The Long Summer, he postulated that civilization arose after the last ice age because the climate stabilized after the ice age, not because humans changed in any real way. There’s some evidence to back him up. Alvin Alley, in the Two Mile Time Machine, talks about Dansgaard-Oeschger (D-O) events in the glacial record. These are times when the global temperature bounces back and forth many degrees, and they are thought to be due to ice from Hudson’s Bay glaciers messing up global thermohaline circulation in a semi-periodic way. Basically, the climate at Glacial Maximum is stably cold, the climate in the interglacial is stably warm, and the times between those periods have the climate oscillating between cold, colder, and coldest in something like a 1,500 year pattern with lots of noise. In such a continually changing global environment, things like agriculture would be difficult to impossible, so it’s no surprise that humans would be nomadic hunter-gatherers. If there were something before the D-O events, the evidence would be lost, and the absence of evidence would make us think that, until 5,000 years ago, we were primitive savages.

If you’ve been following the news, you know that evidence for agriculture 23,000 years ago turned up in Israel (link to article). The last glacial maximum happened from 26,000-19,000 years ago. If one believes that stable climates make things like agriculture possible, then it’s easy to believe that someone invented farming during the last glacial maximum, and that it was lost when the D-O events started up and their culture shattered.

So how often did humans go through this, discover and lose agriculture? We have no clue. Except for that fortuitous find in the Sea of Galilee, when a long drought temporarily revealed an archaeological site that is currently underwater again, there’s no other evidence for truly ancient agriculture.

The last interglacial was the Eemian, 130,000-115,000 years ago. Did the Neanderthals invent agriculture back then? There’s little undisputed fossil or archaeological evidence from that time, and who knows if any evidence still exists. What we do know is that the Eemian people did not smelt a lot of metal, for there were ample ore deposits waiting for us to find them on the surface. We know they didn’t use petroleum or coal for the same reason, and there’s no evidence that they moved massive amounts of Earth or built great pyramids, as we’ve done. Those kinds of evidence seem to last. But if they had small neolithic farming towns, especially in northern Europe, the evidence would have disappeared in the subsequent glaciation.

This pattern applies to our future too, especially if climate change collapses our civilization and forces the few survivors to be hunters and gatherers. Our civilization would lose continuity, our history would vanish, our flimsy concrete buildings would collapse into rubble, and coastal ruins would disappear under the rising sea. What would remain of us, except our earthworks and our descendants? My rough guess is that such an age of barbarism would last between 200 and 2,000 years before the climate stabilized and civilization became possible again. Would the people building their civilization on the other side think they were the first civilized people, too, that their history began when they were created a few thousand years prior, as we used to think?

That may be the fate of future humanity on Earth, even if our species lasts a billion years. When the climate is stable for thousands of years, there will be outbreaks of humanity–what we call civilization, when we temporarily escape nature’s constraints, grow fruitful, and multiply to fill the place. In between these outbreaks there will be far fewer of us, and we’ll live in smaller, simpler societies. What we will know will be a balance between what we’ve retained and (re)discovered, and what crisis, collapse, and continual change has caused us to lose. Our history, at any one time, will be that brief window of a few thousand years between discovery and loss, with only enigmatic artifacts, like those 23,000 year-old seeds, to tell us that we weren’t the first ones to discover something. They’ll be enough to hint at how much history we’ve lost, but not enough to let us recover it.

Hobbits of the ATM?

No, I haven’t seen the latest offering Peter Jackson yet, but I will soon. Still, in honor of the latest, erm, extension of The Hobbit onto the big screen, I thought I’d pitch out an interesting possibility for the future of at least some of our descendents.

First, a definition: ATM isn’t the money machine. Rather, it’s an acronym for Anthropocene Thermal Maximum, which we’ll hit sometime after we’ve exhausted all the fossil fuels we’re willing to dig up into the atmosphere. If we blow off over something like 2500 gigatonnes of carbon, we’re going to be in the range of the PETM, the Paleocene-Eocene Thermal Maximum (Wikipedia link) about 55.8 million years ago, when global temperatures got as hot as they have been in the last 60 million years. Our descendents’ future will be similar, if we can’t get that whole carbon-neutral energy economy working.

One of the interesting recent findings is that mammals shrank up to 30 percent during the PETM (link to press release). The reason given by the researchers is that increased CO2 causes plants to grow more foliage and fewer fruits (in the botanical sense, so we’re talking fruits, nuts, grains, and all the other things we like to eat). This poorer nutrition led to smaller animals. I think there’s another possible explanation for the decrease in animal size.

My thought was that, if civilization crashes due to radical climate change into a PETM-type world, humans will be at the mercy of the elements, so it’s quite likely that future people will be smaller in size. Perhaps 30 percent smaller? Sitting down with the BMI graph and making a few assumptions, I found that the 30% smaller equivalent of a 71 inch tall male weighing 160 lbs is approximately 60 inches tall. Now, this is an interesting height, because it is the upper limit of pigmy heights in an interesting 2007 study by Migliano et al. in PNAS (link to article). Their hypothesis was that the evolution of pigmies around the world is best explained by significant adult mortality, which they adapted to by shifting from growth to reproduction earlier in their lives. The researchers found that the average age at mortality in pigmies is 16-24, and few live into their 40s. The major cause of death is disease, rather than starvation or accidents.

While I don’t know of any evidence of increased animal disease during the PETM, there is good evidence for increased plant disease and predation by insects (link), so it’s not much of a stretch to hypothesize that the animal dwarfing could have been caused by increased disease, decreased lifespans, and a resulting shift towards smaller body size and early reproduction.

So, here’s the idea: if we blow too much carbon into the air, and our ATM rivals or exceeds the PETM, at least some of our descendents will be the size of pigmies, due to the harsher environment (more disease, less medical care) favoring people who mature earlier and have kids as teenagers. They probably won’t be hobbits unless a hairy-footed morph takes off somewhere (perhaps in the jungles of Northern California?), but they will be technically pigmies.

It’s not the most pleasant thought, but if short lives and statures is troubling, the good news is that post-PETM fossils show that animal species regained their former size once the carbon was out of the air. And, according to Colin Turnbull’s The Forest People, life as a pigmy isn’t necessarily nasty or brutish, even if it’s short.

Interstellar Civilization and Cthulhu

Time for something different. Admittedly, it’s inspired in part by Matt Wedel’s recent musings on how to make a proper Cthulhu idol. Since it’s July, I figured I’d trot out something I’ve been musing about. It has to do with vernal pools. And Cthulhu. And interstellar civilization.

Vernal pools, in case you don’t know, are rain-fed pools that crop up in the spring. I’m used to the California ones, which feature a wide variety of (typically rare to endangered) species that act as typical aquatic or wetland species, but only for the few weeks to months that the pools last. They have a couple of neat properties that are relevant here. One is that vernal pool species have a number of ways of dealing with the inevitable death of the pool, from flying to another pool to going into hibernation to producing propagules (seeds, eggs, etc) that can survive up to a century before they grow once a new pool forms. The other thing to know is that organisms in the pool typically start at the small end (fairy shrimp, algae), followed by bigger ones (tadpoles, small aquatic plants), followed by “large” predators (dragonfly larvae, beetle larvae), followed finally by the really big things (ducks, garter snakes) as the pool dries. It all happens quite fast, a miniature serengeti, as someone called it.

If you don’t know what Cthulhu is, well, what can I say? Go read The Call of Cthulhu, and come back later. But this is more about Lovecraft’s whole mythos of critters that lived in deep time and still live here and there, ready to jump out and go boo. Erm… Right.

Lovecraft didn’t know much about math or biology, for which I don’t blame him. It wasn’t his thing. Still, rather a lot of science has floated under the bridge since he wrote in the 1920s and 1930s, so I’d suggest it’s high time to retcon the Cthulhu mythos into modern science. That, and it’s July. In that spirit, I’d like to suggest an interstellar civilization composed of Mythos monsters, and based in part on the model of a vernal pool.

Let’s start with our galaxy. By most measures, there seem to be millions of potentially habitable planets out there, but equally, in our world, we don’t see any evidence of interstellar cultures. This is slightly bizarre, as sun-like stars have been around from something like 500 million years longer than our sun has existed. One would guess that, if interstellar civilization could exist, it would exist, and that furthermore, it would have colonized Earth long ago. That is exactly what Lovecraft posited, with his fossil cities in At the Mountains of Madness, The Shadow Out of Time, and elsewhere. Personally, I think his reasons for why we’re not over-run by alien beasties are a bit weak, so this is where the retcon starts.

The big problem with interstellar civilization is that traveling between stars is horribly energy and resource expensive. Lovecraft got it right, when he talked about species migrating between the stars, rather than commuting (although his Outer Gods seem to not have that trouble). It follows then that when a interstellar civilization colonizes a planet, resource extraction begins in earnest. We’re not talking about sustainability here, not by a long shot.

Since we know what a non-sustainable civilization looks like (we’re living in one), we also know that, absent major changes, such civilizations die out in a geologic instant. This may sound non-functional, but there’s a way out of it. If the interstellar civilization on a particular world can colonize one or more new planets before the civilization dies, it can keep going. Planets recover from civilization over a 10-65 million year period (thanks to geologic processes that allow the biosphere to recover, new oil reserves that gather surplus sunlight, and erosion that uncovers ore deposits), so it’s theoretically possible for a really clever interstellar civilization to persist indefinitely by constantly moving, leaving most of the hundreds of millions of habitable worlds in the galaxy fallow for most of the time. When the civilization ends on a planet, its constituents either leave, die off, hibernate, or leave some sort of remnant or propagule to grow when civilization comes again, tens of millions of years later. Granted, it’s tricky for anything to survive intact for tens of millions of years, but with god-like technology comes god-like hibernation abilities.

So what happens when civilization rains down on a planet? I suspect it’s a lot like what happens when a vernal pool fills. The little guys (elder things and their shoggoth bionanotech) show up first and most frequently. If the planet’s biosphere isn’t that suitable, that may be all that shows up, and they leave after they’ve sucked up the available resources to move on to the next suitable planet. If conditions are more favorable, the elder things are followed by all manner of beings: mi-go, the Great Race, and so forth, each preying on (excuse me, establishing trade relations with) the things that came before.

Then Cthulhu and his kind show up. They’re the megacorps, excuse me, the big predators. However, Cthulhu has an odd biology. According to the Call of Cthulhu“[w]hen the stars were right, They could plunge from world to world through the sky; but when the stars were wrong, They could not live.” In biological terminology, Cthulhu and his ilk use two strategies: interstellar travel (“plunging through the sky”), presumably if the stars are close enough for them to make the transit, and they also can go dormant (“could not live”), presumably through some amazingly advanced form of anhydrobiosis, to wait between boughts of civilization. Once Cthulhu’s kind is through ravaging a planet, the show’s over, and those survivors who didn’t flee settle in to wait for the planet to heal itself. This is much like what happens when a vernal pool dries to mud. The flowers bloom in the mud, and everything sets up to wait through another dry summer

Note that colonization isn’t an organized process, but then again, vernal pool community formation isn’t organized either. Every pool is different every year, and it depends on things like how fast the pools are evaporating and what animals are close enough to colonize the pools. Most of them can pass a year (or hundred) without needing water. Similarly, interstellar civilization is conditioned by how far a particular species can travel between stars and by what they need to survive on a planet, whether they can pioneer an uncivilized ecosystem (as the elder things can), or whether they need a civilization present to feed their great bulk (as with Cthulhu).

When Lovecraft talked about ancient cities, his biggest problem was lack of a viable dating technology. He wrongly assumed that species had been on Earth for hundreds of millions of year due to fragments throughout the geologic record, when in fact the planet was settled repeatedly, at different times, tens or hundreds of millions of years apart. It’s an easy mistake to make.

We can even understand the nature of Lovecraft’s Other Gods in this scheme. Azathoth, the blind idiot god (or demon sultan) at the center of the universe is pretty clearly the black hole at the center of our galaxy. Without it, this galaxy wouldn’t exist, so it is our creator in its own mindless way. Yog-Sothoth, the All-in-One and One-in-All of limitless being and self, is probably our galaxy’s equivalent of the Internet, possibly powered in part by the central black hole Azathoth. After all, if civilized species don’t know what’s going on on other worlds, how can they know where to migrate next? Nyarlathotep, “that frightful soul and messenger of infinity’s Other Gods, the crawling chaos,” is Yog-Sothoth’s equivalent of Siri, or perhaps Clippy the Paperclip, which may explain humanity’s generally negative interactions with it.

This leads to some interesting ideas. Paleontology in Lovecraft’s world is likely to be rather more interesting than our world’s paleontology. Think of what the remnants of an alien interstellar city would look like in the fossil record. Moreover, there would be a rather more sinister explanation for Earth’s mass extinctions, and the evidence would be rather different.

Of course, the ultimate question for humans is, when the stars come right and galactic civilization comes to this planet yet again, do we join in the madness and plunge between the stars with them, do we resist, or do we hide out until they go away, and hope we can survive on the scraps left behind?

Apocalyptic fun: 34 future apocalypses

I’ve gotten rather tired of the Mayan apocalypse, and being a contrarian, I’ve been thinking more about the deep future instead of the end of the world.

At some point, I made a sarcastic remark about wanting to write about a world “after the 34th apocalypse, except that I’m too lazy to come up with 33 separate apocalypses.” Now, as 12/21/12 comes closer, I’d thought it might be fun to crowd-source the other 33 apocalypses.

The idea of this is to provide future worlds for SF people to play with. Right now, I feel like SF is suffering from “aging white myopia” in that it’s mostly about the fears and fantasies of aging white people (often men), and myopia because most of the serious SF predictions are in the near future, not the deep future. I’d rather start thinking about 21st century problems, which are more about “how do we deal with this crazy world the Baby Boomers left us” than worrying about the death of the dreams we had as teens.

Want to play? Since I’m hoping to crowd source the apocalypses, I’m perfectly happy if people swipe ideas from here. This is about thinking creatively about global crises, and what comes after them.

Anyway, let’s get to the apocalypses

Here are the end points
1. The First Apocalypse is happening now, with a 5000 gigatonne release of carbon into the atmosphere over the next 200 years (this is the IPCC extreme scenario discussed here. This is the path we’re currently on. Temperatures (and extreme weather) peak between 2500 and 3500 AD, with global mean temperatures peaking 9 to 16 degrees F (6 to 9 deg. C) above today. Sea level rises about 230 feet (80 meters) above today, but it reaches that maximum in 3500 AD (almost all rise happens by 3000 AD). Conditions take 500,000 years to get back to what we have today, and we can assume the fall back towards normal in an approximately linear fashion. Thermal gradients between the arctic and the tropics largely disappear at first, but gradually reappear.
2. The 34th Apocalypse happens 525,000 years from now, when the next ice age starts. This is by fiat, from eyeballing the insolation graphs on Wikipedia. At this point, the last remnants of arctic and high mountain civilization are plowed under by the growing glaciers (antarctic civilization finally disappeared in 400,000 AD under the resurgent southern ice cap). This cycle looks a lot like the last Wisconsin glaciation. Due to the profligacy of the 1st Apocalypse, there is no fossil fuel left to rewarm the earth to avoid the ice.

Those are the end point apocalypses. Here are some ground rules:
–What’s an apocalypse? It’s a global event that causes massive change, global migration, and the end of civilization as we know it, although not necessarily a return to the stone age. It does NOT cause human extinction. It can be natural (an ice age, megavolcano, asteroid), or manmade (our current Gigafart).
–Apocalypses have dates attached, but they aren’t necessarily instantaneous. The Gigafart will take 1500 years to reach its full ripeness.
–Apocalypses have stories attached. Where does Apophis land, and what happens during the impact and afterwards?
–There’s time between apocalypses, time enough for human cultures to recover. In 525,000 AD, there will be enough history, myth, archeology, and paleontology, for the people of that time to know that 33 apocalypses have happened before them, and that they are facing the 34th. This means that the people living between apocalypses have to leave a traces. What do they leave behind that survives?
–The Rule of Narrative Conservation: people will be recognizably human 525,000 years from now. Yes, that’s a long time in human evolutionary terms, but this is for our personal fun. “Recognizably human” means that future people will be close enough to us that it’s no stretch for writers to write about them and readers to emphasize with them. They’re born, live, love, and die, and have recognizable conflicts. There is no end of history, and there is no point at which people stop being people. It does not mean that people will be the same as they are today, and it especially does not mean that they will have the same races as we do today. Races change over the course of a millennium or two, and 525,000 years is an enormous time for racial change.
–I’m tired of reading about zombies, werewolves, and vampires. If you want a monster pandemic apocalypse, be more original.
–Science rules. Don’t bother with Cthulhu, Godzilla, alien invasions (cf the Fermi Paradox), or fairies coming back. Similarly, don’t bother with nanotech or synthbio disassembler plagues, unless you can explain in detail how the damn things work from a biochemical and energetics point of view. Otherwise, they’re magic fairy dust, and that ain’t science.

Those are the basic rules.

One Prebuttal: The simplest way to come up with 32 apocalypses is to assume that global technological civilization is a destructive bubble that pops. All we have to assume is that it takes about 500 years (on average) for global civilization to grow and collapse, and it takes an average of 15,000 years for the Earth to recover enough to support another global civilization, during which people are stuck living as hunter-gatherers, dirt-scratching farmers, and similar Arcadian folk. This idea has been done by Larry Niven et al (The Mote in God’s Eye) and Charles Stross (Palimpsest). I don’t mind the idea of civilization as a cyclical irruption in history, but you know, I’m really hoping for something more original. Future history as a drunkard’s walk, rather than a wheel of time. What about two or more cycles of history, spiked with various and epic natural disasters? Or are there 32 totally predictable global catastrophes lurking out there? Or some mix of both?

Come play Edward Gorey with the future. If we get 34 separate apocalypses, I’ll put it all together and send it out to everyone who contributed.

Grim Meat-Hook Future, Part 1: So we can build a starship….

Okay, not quite in the original sense; However, I thought I’d play with a simple idea.  In the future, we can build a starship, specifically a slower-than-light starship that obeys the laws of physics as we currently know them.

What will Earth look like in this case?

Let’s unpack this scenario a bit.  For a starship to work, we will need to have developed a bunch of technologies and practices that we currently don’t have.

These include:
–small biospheres that can support people for long periods of time without breaking down. Remember what happened with Biosphere 2? That’s what I mean by break down.
–light-weight shielding that can deal with debris hitting it at absurdly high velocities.
–Either cheap, compact, very, very safe fusion that can burn continuously for decades (for a torch ship), antimatter that can be cheaply made and safely stored for centuries, rather enormous lasers that can fire for decades, and can be aimed with nanometer precision (for a laser sail), or some form of highly accurate, high-powered linear accelerator and “smart particles” that can be cheaply made, fly at relativistic velocities, and steer themselves with nanometer precision (for a beamrider).
–The social engineering to keep small groups working together for multiple generations, or the ability to store humans in some form of stasis for centuries. Remember what happened with Biosphere 2? We’ll have to do much better than that.

The thing about this is that the world will have these technologies, as do the starships. While the technology will be unevenly distributed, bits and pieces of it will be in use all over the planet. For example, if we have fusion, we likely won’t be using fossil fuels for much of anything, because most large metropolitan areas will have fusion plants. They likely will use these energy to power desalination/water purification plants, so that we can all live by the coast and not worry about continents drying up. As I noted in a previous post, we’re stuck with climate for millennia, regardless. I’m not sure where the waste heat goes or how one maintains one of these magic power plants, but based on current experimental plants, it looks like it requires precision engineering at a scale we can’t yet match. This, in turn, implies a stable infrastructure of some scary-good engineers.

In fact, all of these require a lot of really, really good engineers, which means there will be the infrastructure to educate those engineers, whether they are humans, computers, or both. What does that mean for, oh, consumer electronics, aside from having stuff that’s much more complex than what we have today? Who knows?

But let’s look at the other new technology. Small biospheres implies that arcologies are possible. People can build floating “sea castles,” live in domes in the Arctic, on the sea bottom, or in Saudi Arabia’s empty quarter, or anywhere, and live off whatever they can grow in the domes. If they have enough money, that is. Cities will likely use this technology to produce more food within bounds, while wealthy separatist groups flourish wherever they can set up their biosphere.

Things get really interesting when you look at the shielding issue. I don’t know if the shields on a starship could withstand a nuclear explosion, but I do think they’d be impervious to almost all conventional arms. In other words, for the first time since the Middle Ages, defense becomes an option, and castles make sense. They make even more sense if you can live inside one indefinitely, treating it in effect like a starship without an engine. Of course, this radically changes the face of war. I don’t know whether the great powers will go in for castle-busting munitions (terawatt lasers, perhaps?), or more covert action, but basically, every evil genius with plans for world domination now gets his impregnable secret fortress, fully staffed with loyal minions.

Scary thought, isn’t it? We can also ponder the lives of the people who choose to live inside such fortresses. Presumably, it will be possible for them to live in there indefinitely, or to hold themselves in stasis “until the stars are right,” but I doubt it will be what we lazy, middle-class Americans consider to be a Good Time.

Does this sound like an appealing world? I’m not so sure. It’s likely more Neuromancer than Star Trek. That’s the thing I wanted to bring out: a star-faring culture would look very different than what we normally see in science fiction. It will have a technical infrastructure far beyond what we have today, but there’s no particular reason to think that it’s going to be a utopia where domestic robots attend to our every whim. It could just as easily be a weed-infested world dominated by the domed and armored cities of the wealthy and powerful. The only good news will be that people are willing to live that way.

So here’s the question: what did I miss? Any other easy extrapolations?

The Interstellar Two-Step

Let’s assume, for the moment, that interstellar travel is possible. Let’s further assume that there’s no magic wand of teleportation or FTL, traveling to another star takes a looong time, and it basically means colonizing your starship (or gaiaspore, if starship is too passe for you). The ship may be Charlie Stross’s hollowed out asteroid, or a comet, or something similarly large, but whatever the ship looks like, the basic idea is that people don’t put their lives on hold for the duration of the trip. Rather, they settle into their ship, and then they (or their distant descendents) settle another world elsewhere.

The two-step is an environmental filter. Many technologies that are ubiquitous on Earth, such as cooking knives or internal combustion engines, are non-starters in free fall (where scissors work better) or in small biospheres (gasoline engines). Consequently, interstellar travelers will abandon quite a lot of Earth’s technology when they live in space. They’ll also certainly invent lots of uses for vacuum and all sorts of high energy particles, but that’s another story.

Anyway, once they’ve made the first step of abandoning Earth tech and its associated culture (no car culture in space), once they get to another planet, they’re faced with a new environment where they have to adapt again. Suddenly they have dependable gravity and a huge biosphere to draw on (or at least, a planet’s worth of resources). In the second step, do they simply adapt spacer culture and technology to meet the challenges of the new place, or do they read through copies of the ancient Wikipedia and start experimenting with, say, gasoline engines again?

There’s a real-life analogy to this process: Polynesia. As the Lapita peoples settled the Pacific, they abandoned things like pottery, weaving, and flaking rock (and possibly bronze metallurgy) as part of their adaptation to living on coral atolls. Once they colonized places like New Zealand, they didn’t spontaneously pick up their ancestor’s technologies, even though they had the resources (such as clay) to do them again. Instead, they adapted their Polynesian tool kits to new surroundings.

There are some subtleties here: for example, Polynesians didn’t just abandon pots because there was no clay on atolls. They were abandoning them before they got to the atolls, because they were switching from cooking over an open fire (where pots are useful) to cooking in an earth oven (where pots are useless). Moreover pots are more fragile than wooden bowls, coconut shells, and gourds. Similarly, they switched from flaking rock edges (on obsidian) to grinding, because grinding works on all sorts of materials, including the giant clam shells used for adze blades on atolls, while flaking just works on glassy rocks. The thing is, adzes work better when they’re ground rather than flaked (whatever they’re made of), the Polynesians also had bamboo (which can be shaped with an adze to make a nice sharp knife), and Easter Islanders figured out how to flake knives on their own in any case. The bottom line is that loss of technology isn’t just about losing the tech, its involves a whole shift to other tools and practices that sometimes makes things superfluous. A society on electric cars won’t be exactly the same as a society built around gasoline cars, because the two vehicles have different strengths and weaknesses.

Getting back to the interstellar two-step, it’s a fun to play as a thought game. If you were leaving Earth for space, what would you abandon? If you were planning on getting your descendents to settle elsewhere, would you have them do: resurrect Earth culture, adapt spacer culture, or both?

Examples of adapting spacer culture might range from using scissors and shears in place of knives, to using air guns instead of gunpowder, to using various cooking techniques that work regardless of gravity, but not gravity-requiring methods such as frying. How about transportation? Art? Agriculture? For example, if they kept goats in space, would you have them bring along cow embryos and the means to grow them to re-establish cattle, or would you rather give them the biotechnology to engineer a giant goat that fulfills most of the cow’s roles in terrestrial agriculture?

What do you think? How would you do the Interstellar Two-Step? I’ll say right off that there’s no right answer. This is a thought game, pure and simple.

Prelude to a Starship

On Charlie Stross’ blog, I think I called starships gaiaspores, because apparently the term “starship” is passe among the cognoscenti. Or something like that. Gaiaspore does have a certain endearing clunkiness, so use it if you wish. I’m mostly calling them starships here.

But I’m thinking about something a bit different. What comes before the starship? If you remember James Burke’s Connections from the late 1970s, you remember that no invention comes about without a long chain of preliminary discoveries. For living in space, we’re going to need a lot of precursors. What are they?

Let’s start science fiction: how do others see us getting to the stars? The science fiction answers range from, well what we have now (Scalzi’s Old Man’s War, where Ohio hadn’t changed at all in 200 years, except that the elderly now emigrate to the stars) to planetary destruction (Octavia Butler’s Xenogenesis trilogy, where the living, moon-sized spaceships basically ate planets down to the mantle before departing). Charlie Stross seems to break on the large side of the spectrum, talking about hollowing out asteroids and putting slow motors on them. That would require us to digest a few large cities, at the very least.

Assuming a starship is even feasible, it’s going to demand some things we’re currently really bad at, like living at close quarters with nuclear or fusion plants, living sustainably, and living in free fall or microgravity. No culture on Earth lives this way now (although people try it for a few years as an experiment).

So culturally, how do we get there from here? Cultural evolution tends to be path dependent, so it’s not as simple as re-educating the people we have. Imagine turning a Tea Partier into an 18th Century Japanese farmer, or a Papuan highland farmer (both picked because they lived fairly sustainably), and you’ll see the problem. Because of the path dependence, it’s fun to think about where we need to be going before our culture evolves to the point where it can live in space.

What do you think? What do the predecessors to the stars look like? Remember that a pre-starfaring culture has to work on its own merits. Like a bird ancestor, it can’t “half fly.” Those too-small wings have to perfectly good for something else first.

When I wrote Scion of the Zodiac, I cheated on this question. I assumed that we’re going into a post-oil dark age first, and that somehow in that unrecorded time (heh heh) we learned the critical lessons of sustainability that allowed us to go to the stars after the next Renaissance (spurred, I think, by discovering a readable copy of Wikipedia and translating it. No sarcasm there). However, I’ll admit that I was more interested in low tech terraforming than star flight, so I spent more time figuring out how you could survive in an alien biosphere at a low tech level. That last stipulation was so that I couldn’t use magic tech boxes to make life livable. For my “barefoot gaiaformers,” I used three books as my primary references: Bill Mollison’s An Introduction to Permaculture, Jim Corbett’s Goatwalking, and Paul Stamets’ Mycelium Running. Those three books are ones I’d recommend for any post-oil bookshelf, but there’s a lot of good material in there for how to run a gaiaspore. Note that none of these books are mainstream, which is why I think path dependence matters. As for the mechanical side, I’m only starting to think about it.

Obviously, I can babble about this for hours. But what do you think? Can we get to the stars from here? If so, how do we make the connections, and what do the intermediate culture(s) look like? If not, what’s standing in our way?
