Just a brief note. I saw this newspaper article and wanted to share it:
Here’s a link to the Nature Climate Change article mentioned. I haven’t received a copy yet, as I just emailed the lead author to see if I could get one.
Just in general terms, it’s great to see more climate scientists looking into the deep future. Hot Earth Dreams is based on decade-old work by David Archer (who is a coauthor on this paper), and I’m looking forward to seeing the details from the new model.

I didn’t get to livestyles of posturban peoples this time. That’s the next piece. Indian California was a complex place, with hundreds of peoples and languages and a wide variety of life ways. Modern California’s a massively complicated place, but it’s complicated in very different ways than Indian California was, due its central position in the modern global economy. The High Altithermal will be complicated as well, but in very in different ways than it is now. Here I’m going to write about how California’s jumble of environments shape where (and to some extent how) people live.

For Part 3, I want to start with two numbers: 2,644,443 and 200,000-300,000. The first is what I predict, based on the formula in Hot Earth Dreams, would be California state population in 2100 CE, and I’ll get to how I calculated that in a second. The second is the estimate of how many Indians lived in California before European contact. The first I calculated by finding out California’s current population (rounded up to 39,000,000), it’s current annual growth rate (0.9%), and plugged the numbers into a compound interest equation and ran it out to 2050 (52,888,867. Please check my math). Then I applied the 95% dieoff from civilization collapsing between 2050 and 2100, and came up with a population of 2,644,443. The thing to notice is that this number is still ten times higher than what the state supported before Europeans came along. It’s also almost twice as high as the state population in 1900 (1,485,053), which suggests to me, sadly, that the scenario of a 95% population crash is probably too optimistic for California.

Note, you can read part 1 in the series here.
Biopolitics. Such an ugly, synthetic word, but here I want to talk about the chaotic intersection between biology and politics that’s occurring now, because, unfortunately for prognosticators, it’s a big part of what is going to determine what’s still growing in this state in 2100 CE. The fundamental problem is that, if you’re trying to figure out what’s going to survive a mass extinction and climate change, on the one hand there’s the biology of individual species and their interactions in ecosystems, and on the other hand there’s politics, meaning every thing from peoples’ choice of house plants to international laws.
What I’m going to show here is the mess. It’s not a nice thing to do, but hopefully I can at least show both why environmental politics matters, and why calls to do more studies aren’t distractions, either. In the next post I’ll make some predictions about what comes out of this mess, but as in Hot Earth Dreams, I’m walking through the process here, one essay at a time, figuring out the processes before I talk about the patterns that might result.

One of the things that bugs me is that, about half the time when I dawdle on writing something, new facts emerge that change everything. That’s happened here a bit.
This is part one of a series of blog posts about California in the High Altithermal, and here I’m focusing on the environment. What I’m doing is taking the ideas from Hot Earth Dreams and working to show what might happen in one specific spot, in this case, the area currently defined as the state of California, over a specific time period, in this case, the High Altithermal.
My goal is to show how climate change happens over time, because different things happen on different scales, and that makes the future a lot messier. It’s not meant to scare people, but rather to give us a way to intellectually examine this model of the future, and figure out how people and other organisms will adapt.
If you’ve already read the book, you know the basic global scenario for the High Altithermal, which will run from 2100 CE (when our greenhouse gas emissions from fossil fuels stop) to 3600 CE (when the East Antarctic ice sheet finishes melting, and sea level tops out at 65 meters above the current level). These dates aren’t hard: we don’t know when we’ll finish binging on fossil fuels, what Arctic methane is going to do, or whether or even if the entire East Antarctic ice sheet will melt. But that’s the scenario I’m using here. During the first 200 years of the High Altithermal, global average temperatures climb from +3oC (we’re currently at +1oC) to +8oC, and the Greenland and West Antarctic ice sheets melt, raising sea levels by about 16 meters over those 200 years. From 2300 CE on, global average temperatures stabilize, and then start to fall 1-2oC over the next 1,300 years, while the sea continues to rise as the East Antarctic ice sheet melts away.
In this post, I’ll cover sea level rise, climate, and rivers and dams. This is necessary background, and I’m breaking it up into multiple posts so you don’t have to read a 7,000 word essay.

Last week, I had a great Skype interview with Greg Moffitt, who runs the podcase Legalise Freedom. I was curled up my couch with my computer in my lap to kill the echoes in my place and the tinniness from my computer’s microphone. Greg and I talked for well over an hour, and the edited version of our conversation is up here (opens a new window), if you want to here my voice instead of simply reading it in your head.
I had a lot of fun doing it, and my thanks go to Greg for making my first long interview a really fun experience.

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.
