Global fertility and the climate crisis

Foreign Affairs has an interesting article on “The Age of Depopulation: Surviving a World Gone Gray“.

It describes several hypotheses for explaining the reduced fertility rates and falling populations almost all over the world, but emphasizes that women simply voluntarily don’t want to have as many children:

Pritchett determined that there is an almost one-to-one correspondence around the world between national fertility levels and the number of babies women say they want to have. This finding underscored the central role of volition—of human agency—in fertility patterns.

Personally, I wonder if the ecological crisis is a major background psychological cause. To everyone who is paying attention, the unambiguous message from scientists and policy experts is that we are destroying our own civilization and the capacity of the Earth to support us through our selfish and short-sighted determination to turn burning hydrocarbons into dollars. Even when it comes to my own life, I am profoundly afraid that prosperous, open, and advanced societies will cease to exist as the ecological basis for our entire civilization collapses. I think there is a decent chance – if I live until 2060 or so – that the young people in that time will look at photos of the produce sections in our supermarkets and be unwilling to accept that they were ever real: that we had so much bounty, such tremendous gifts from nature, and we squandered it all because we allowed psychopaths to rule us. It’s even worse than that in democratic societies: we demanded that psychopaths rule us, because we are unwilling to accept the truth of our situation.

Having children when you expect the future to be chaos demands an even greater act of faith from prospective parents. I would say that if we do want more children (which is questionable) we need to stop acting as though the future is something which we can and should destroy for the sake of our near-term ease and convenience.

Lonely, frustrated, angry, and despairing

Lately, I have been feeling dejected and wildly alienated from the rest of humanity. It seems like basically nobody wants to avoid catastrophic climate change. Among those who purport to care, the superficiality the commitment is quickly revealed when they prioritize other objectives ahead of avoiding climate disaster. Government agencies work to defend the status quo: at best, they pretend to take action in order to avoid doing anything that would really make a difference. At worst, governments are the armed wing of the fossil fuel industry itself. Every country with fossil fuel reserves is rushing to develop more production. Even climate change activists care more, in practice, for imposing their social and economic preferences on society than about abolishing fossil fuels.

At times over the last 18 years, working on climate change has felt like a lonely journey but at least one where eventually the world will come around. As each year goes by now, it seems more that humanity is content to fly our plane straight into the ground, while the passengers cheer as they set ever-higher speed records and the captain assures everyone over the intercom that our present course ensures a happy arrival at a welcoming destination.

Everyone is still developing fossil fuels

As my recent blackboard talk emphasized, climate stability means fossil fuel abolition. Arguments to the contrary are cynical mechanisms to keep the petro profits coming, regardless of the consequences for the climate.

Unfortunately, despite endless talk about ‘net zero’ and ‘ensuring’ climate stability, essentially everybody is still chasing fossil fuels:

Remember: it takes decades for the full effects of our greenhouse gas pollution to be fully manifest. That means much worse is still to come, even if we start making the right choices, and a nightmare looms if we persist with our current approaches.

Travis Rector on fossil fuel abolition

About 90% of climate change is from the extraction and use of fossil fuels. We need to stop. As Chapters 6 and 7 point out, this won’t be easy—especially when fighting against industries that stand to lose trillions of dollars from the energy transition. But the rapid growth of wind and solar shows us that it’s already happening. Our role is to help it happen even faster.

Rector, Travis A. “Preface.” In: Rector, Travis A. Climate Change for Astronomers: Causes, consequences, and communication. IOP Publishing, 2024. p. xxi

Also:

We are at a crossroads in the history of our 4.5-billion-year-old planet. These days in which we are alive are precious beyond measure, especially from the perspective of Earthlings who come after us. Every day the fossil fuel industry continues to exist makes our planet hotter, taking us more deeply into irreversible catastrophe. The only way out is to end the fossil fuel industry; the faster we do, the more we will save… It is incredibly important to fight the fossil fuel industry, which has captured world leaders and international climate negotiations.

Hale on why climate stability advocates are often confounded

The combination of uncertainty and low salience, in turn, enables obstructionism, the ability of interests tied to the status quo to maintain their interests. Consider the hurdles of a policy entrepreneur would have to overcome to create and implement a policy addressing a problem with distant effects like climate change. First, that policy entrepreneur would have to herself see value in pursuing an obscure issue, one that is unlikely to garner her a quick win and the associated political benefits. Few will have incentives to pursue such causes. Second, she would have to mobilize a sufficient coalition of interests to be able to influence policy. This would require each of those interests choosing to focus on a distant topic over their more urgent priorities. Third, this interest coalition would need to force the issue onto the broader political agenda, competing for limited space with numerous immediate priorities. Fourth, the coalition would need to somehow overcome, compensate, or neutralize political opponents.

To the extent those opponents are worried about the short-term costs of action, everything that is hard for the long-sighted policy entrepreneur will be easy for them. Opposing long-sighted policy—that is, promoting short-term outcomes—will give them the opportunity for quick wins on issues that are relatively easy to mobilize interests around. And even if the long-term-oriented policy entrepreneur wins a battle, she must preserve and maintain those gains permanently, as opponents will seek to reverse any defeats they face. A one-off victory may be important, but long problems often require sustained policies over time, while it only takes one victory by opponents to block them. The longer a problem’s effects reach into the future, the more friction the policy entrepreneur will face at every stage, and, should she get a win, the more enduring her victories will need to be.

Humans struggle with allocating losses

Canada seems to have a weird atmosphere of being in a recession, but without that term being used and without the definition (in terms of GDP growth or contraction) being met.

This starts to make more sense when you see that the GDP growth is largely the result of population growth and growth in the labour supply – not increased output per worker. GDP per capita was $58,304 in Q1 of 2020 and $58,111 in Q4 of 2023. Meanwhile, according to the Bank of Canada’s inflation calculator, inflation has averaged 4% per year over the span, so C$100 in 2024 buys what C$85.48 would have bought in 2020. The average Canadian is getting poorer, even with all the stimulus that was given out over the pandemic and with all the new debt which has been accumulated. I personally think governments have been pulling out all stops to keep asset prices (especially stocks and houses) high since the 2008 financial crisis, with very little consideration of what those measures are doing to the non-affluent and those in future generations.

This is worrisome both in the immediate context and as a broader signifier. Daniel Kahneman’s Thinking Fast and Slow stresses how people experience gains differently from losses, and find a loss of any size more aversive than they find a gain of that size pleasurable. He comments on the social and political implications:

If you are set to look for it, the asymmetric intensity of the motives to avoid losses and to achieve gains show up almost everywhere. It is an ever-present feature of negotiations, especially of negotiations of an existing contract, the typical situation in labor negotiations and in international discussions of trade or arms limitations. The existing terms define reference points, and a proposed change in any aspect of the agreement is inevitably viewed as a concession that one side makes to the other. Loss aversion creates an asymmetry that makes agreements difficult to reach. The concessions you make to me are my gains, but they are your losses; they cause you more pain than they give me pleasure. Inevitably, you will place a higher value on them than I do. The same is true, of course, of the very painful concessions you demand from me, which you do not appear to value sufficiently! Negotiations over a shrinking pie are especially difficult, because they require an allocation of losses. People tend to be much more easygoing when they bargain over an expanded pie. (p. 304)

Globally, this pattern is alarming too. Humanity is choosing to persist in activities which we know will cause catastrophic climate change, loss of wealth, and unprecedented damage to the natural world which sustains us. We are also massively failing to invest enough in non-fossil energy sources to retain our current standard of life. This is setting us up for brutal inter- and intra-national fights over allocating losses.

Shrugging our way through the breakdown of a stable world

Lately, in observing our politics and dealing with our society, I feel like a time traveller who has been sent back to before the forthcoming collapse. There is no success to be had in warning people though. They sense and feel that the collapse is coming, and that they are unwilling to make the changes that might avoid it. It’s not that people don’t believe the warning; they do. Apocalypse has become the leitmotif of our culture. People are just too corrupted by self-interest and too pessimistic about the ability of our society to solve problems to believe that anything can be done.
