Gaia Vince’s Nomad Century is a scary, compelling and disturbing book. We all know (even climate change deniers must know) that global warming is real, since we all feel it, and we know it brings massive forest fires and other extreme weather events. There is no longer any reasonable doubt that this is the case. What many of us haven’t considered is that these changes if they progress as they are likely to do, will bring among their unwelcome consequences massive migrations from the places most negatively impacted by climate change (the equatorial zone) to the northern hemisphere, including parts of it that so far have been few people’s favorite destinations, such as northern Canada, Greenland and Siberia. These migrations will happen because many tropical regions will become unlivable for human beings. This is a powerful prediction, one that is very likely to materialize, as places with human presence for tens or thousands of years become deserted. So Vince attempts to frame migration not as a security concern but as a great opportunity to solve the rich North birth dearth and also to reduce human inequality and poverty. Because these migrations will happen, since we very likely won’t be able to limit global warming to safer limits, it makes sense to prepare for them. Here, she is on more solid ground: if a disaster will happen, we should be as prepared as possible to minimize its effects. Then she discusses many practical matters, such as preparing cities for the immigrants, integrating them into productive activity, maximizing the upside for them and for the host society, defusing the hostility of locals. Her discussion of the future of foodstuffs is dispiriting, since most of the time most of us will be forced to become vegetarian, except for occasional treats of insect-based protein. At least she has the good sense to conclude that no democratic society is likely to vote itself into deliberately shrinking its economy for environmental or humanitarian reasons. She praises an immigrant integration program in an Italian city, while decrying that immigrants are expected to be thankful to the host nation whereas in fact being allowed to immigrate is their right under several international conventions which, although correct legally, is also infuriating and unreasonable. She stops short of proposing open borders and there doesn’t seem to be any immigration she doesn’t like, perhaps with a few tweaks. She proposes an international body with binding powers over national governments to make these decisions. All I say is, good luck with that. I can see it happening in a few years. Or not. This is a weakness of the book: she says what she thinks must be done and often says cogent and interesting things, but she seems to be tone deaf to the viability of her proposals. Developed countries are unlikely to invite millions of third worlders to move in with them, as they are unlikely to spend billions preparing for their arrival or to spend billions helping the worst off out of a sense of responsibility for having caused global warming. Americans haven’t even gotten around to indemnifying the descendants of slaves, and slavery ended 160 years ago. In fact, countries are probably more likely to withdraw from international agreements mandating they welcome refugees and other migrants and to retreat behind walls both physical and legal to avoid them. It probably won’t work, and it will hurt both the migrants and the rich countries, but it is likely to be so, human nature being what it is.
While I agree that migrations will happen, I have a much less rosy view of them than does the author. My country (Colombia) has generally been a source of migrants rather than a recipient, until recent times when we have been forced to receive over 2.000.000 refugees from the Venezuelan failed state. We have also become a transit point for immigrants from all over the world who aim to get into the US via Mexico. While former migrations (of Italians, Jews and Arabs, mainly) to our country did enrich our culture and improve our economy, I have failed to see similar benefits in the more recent ones. Massive migrations driven by economic crises are more likely to turn bad than more selective ones happening at various times and in various places (most of our current migrations are arriving to our largest cities, mainly the capital).
It seems climate-driven migrations would be more similar to the massive “bad” migrations than to the selective “good” migrations. Vince does not see this. She even praises the famous “Mariel” migration from Cuba into the US in 1980 without even mentioning that many of the migrants were common criminals that Castro set upon the US. She ignores the fact that many third world countries (including Colombia) have large and well established criminal organizations that tend to take advantage of the trust of the host country. This is already happening in many European countries, most notably The Netherlands, which has been riven by narcotic organization violence in recent times. She doesn’t address how to prevent more unlovely aspects of migrant cultures, such as forced marriages, honor killings and ritual genital mutilations from moving in along with the migrants. She simply assumes these habits will rot away in the presence of a superior liberal culture. That this hasn’t happened in European countries after decades of migration, she doesn’t consider. She says that the second generation of immigrants is much more likely to imbibe the local values than fall prey to extremism, but this doesn’t consider the many cases where the opposite happens: where the parents are more secular and the children more ideological. Her assumption that, because fertility has dropped beyond replacement point, rich societies need immigrants to take up the slack is spot on, but she doesn’t seriously engage with concerns about what short is people these will be. As a result of recent migrations and as a resident in one is the premier melting pot cities (London), the author has nothing bad to say about it, which is understandable. Yet it may fail to convince people in dissimilar situations, which I expect is not a small number.
This is not to say that Vince isn’t right, migrations will intensify as a result of climate change. Appealing to high minded motivations (such as reducing global inequality and extreme poverty, preserving life and helping those hurt by the rich countries’ policies) is of course reasonable, although these arguments are unlikely to convince the large groups that voted for Brexit and elected (and may yet reelect Trump). She also appeals to self interest on part of the rich countries, that is probably a better bet.
Except for a brief reference to a massive migration in prehistoric times that resulted in the death of 90% of the residents of the invaded territory, she does not seriously consider the risks that migration will produce, particularly if improperly managed. She could have told the story of Roman emperor Valens and a barbarian Gothic tribe, the Thervingi. In 376 AD the Thervingi, whose territory was under pressure from invaders (sorry, migrants) from the Asian steppes, requested the emperor to allow them to settle on the empire’s border, they offered to fight on the empire’s behalf against other, even more fearsome, barbarians. Their request granted, the Thervingi’s entry into the empire was not a success. They had to ford a swollen river, where many died, and when they arrived there was not enough food or shelter for them, since their numbers had been underestimated and local commanders took advantage of them and sold them at inflated prices the food that the emperor had ordered be given them for free. The Thervingi, whose weapons had not been confiscated as was the policy, revolted and other barbarians, the Greuthungi, took advantage and crossed the border. There followed years of war, that ended with emperor Valens’s death. The empire never recovered. The Goths were allowed to settle as a group on their own largely self ruled territory, where they became a threat to the security of the empire and eventually contributed to its division and downfall. It’s easy to image something like that happening as a consequence of the near future climate migrations, if they are mishandled, which they probably will be, human nature being what it is.
