The Precipice
From one of the world's leading moral voices, this urgent and eye-opening book makes the case that protecting humanity's future is the central challenge of our time. If all goes well, human history is just beginning. Our species could survive for billions of years - enough time to end disease, poverty, and injustice, and to flourish in ways unimaginable today. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, where we face existential catastrophes - those from which we could never come back. Since then, these dangers have only multiplied, from climate change to engineered pathogens and artificial intelligence. If we do not act fast to reach a place of safety, it will soon be too late. Drawing on over a decade of research, The Precipice explores the cutting-edge science behind the risks we face. It puts them in the context of the greater story of humanity: showing how ending these risks is among the most pressing moral issues of our time. And it points the way forward, to the actions and strategies that can safeguard humanity. An Oxford philosopher committed to putting ideas into action, Toby Ord has advised the US National Intelligence Council, the UK Prime Minister's Office, and the World Bank on the biggest questions facing humanity. In The Precipice, he offers a startling reassessment of human history, the future we are failing to protect, and the steps we must take to ensure that our generation is not the last.

- The cascading risks you mention are certainly real and serious, and are worthy of our best and urgent efforts to solve. Effective altruists are rightly concerned about these effects e.g. https://80000hours.org/problem-profiles/climate-change/
My comment was written with the summary of that article in mind (I didn't make this clear):
> Climate change is going to significantly and negatively impact the world. Its impacts on the poorest people in our society and our planet’s biodiversity are cause for particular concern. Looking at the worst possible scenarios, it could be an important factor that increases existential threats from other sources, like great power conflicts, nuclear war, or pandemics. But because the worst potential consequences seem to run through those other sources, and these other risks seem larger and more neglected, we think most readers can have a greater impact in expectation working directly on one of these other risks.
There is an excellent chapter on the existential risks associated with climate change in Toby Ord's book The Precipice, which you can get a free copy of at https://80000hours.org/the-precipice/
- The article gives the example of us deciding how much we should pay as a society to reduce the number of road deaths. Do we count only the lives of the people who would otherwise die in the accidents? Or do we also count the lives of the children that they might have?
Valuing descendants gets you to weird conclusions pretty quickly: preventing the death of someone in a culture where people typically have large numbers of children would seem much more important than saving the life of someone past childbearing age as you consider the exponential increase in descendents over time.
Similarly, there are likely a lot of ways that you could increase the number of children born other than by preventing the deaths of their would-be parents. Policies that made housing, childcare, and education cheaper could have a very large impact -- I know a lot of people who have decided to have fewer kids than they otherwise would have because of the cost.
Even more dramatically, consider policies that have an effect on whether humanity continues to exist. If we wipe ourselves out with nukes, bioengineering, etc, that's a lot of potential future people who won't get to exist in addition to all of the current people who would die.
I think Toby Ord's "The Precipice" has a pretty good treatment of these issues, and is very thorough.

An amazing nonfiction book that at times reads like science-fiction. A grand overview of various existential risks humanity faces and what we can do to decrease the chances. As it stands, the author estimates humanity's survival chances to be 5/6 per 100 years, given today's state of things. This is equivalent to playing a Russian roulette - not something we can maintain for the long term. So now is one of the most important times in history of humanity: preventing our not-unlikely total destruction.
- > So why now?
From my reading of degrowth works the answer is: because now the global resource use induced by growth have accumulated enourmous negative externality costs, costs that will nedlessly increase further unless counteracted by degrowth policy. Food shortages, deadly heatwaves, property destruction. Direct dire costs to human health and welfare and rippling secondary effects. For example how would a scenario with hundreds of millions of climate refugees play out on top of current global political tensions?
I see the degrowth view not as "we should never ever have growth again" but rather the current modes of growth have very tangible imminent (on an astronomical timescale) negative effects that we must deal with right now. If we fail to step up to the current challenge of provisioning health and welfare for beings on this planet how likely are we to manage an all universe encompassing expansion without it ending in catastrophe on the largest scale? You could see the climate change challenge, and the degrowth plan to tackle it, as a necessary step to get our house in order, before expanding out.
Us attempting to expand into and shaping the universe is quite a task - so much could go right or wrong. I think Toby Ord's The Precipice[0] has a very useful framework for thinking about such risks.
- A must-read book on this topic is The Precipice by Toby Ord
I also happen to think this is the most important book that has been written this century.
