Climate change is a global problem that is predominantly an intergenerational conflict, and which takes place in a setting where our ethical impulses are weak. This "perfect moral storm" poses a profound challenge to humanity. This book explains how the "perfect storm" metaphor makes sense of our current malaise, and why a better ethics can help see our way out.

Humanity stands at a precipice. -/- Our species could survive for millions of generations — enough time to end disease, poverty, and injustice; to reach new heights of flourishing. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, gaining the power to destroy ourselves, without the wisdom to ensure we won’t. Since then, these dangers have only multiplied, from climate change to engineered pandemics and unaligned artificial intelligence. If we do not (...) act fast to reach a place of safety, it may soon be too late. -/- The Precipice explores the 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 we can take today to safeguard humanity’s future. (shrink)

In this article, we argue that scientists and technologists associated with the nuclear industry are building support for small modular reactors by advancing five rhetorical visions imbued with elements of fantasy that cater to various social expectations. The five visions are as follows: a vision of risk-free energy would eliminate catastrophic accidents and meltdowns. A vision of indigenous self-energization would see SMRs empowering remote communities and developing economies. A vision of water security would see SMR-powered desalination plants satisfying the world’s (...) water needs. A vision of environmental nirvana would see SMRs providing waste-free and carbon-free electricity to preserve the earth’s biosphere. A vision of space exploration would see SMRs assisting in the colonization of the moon, Mars, and possibly other worlds. These visions help create a symbolic convergence among promoters, serving to attract political and financial support, and erasing previous nuclear failures from public discourse. Moreover, underlying these visions is a technological utopian ideal world where SMRs would generate plentiful energy of multiple kinds, offering the necessary means for a life of comfort for all people by meeting various needs and without any environmental externalities or cause for concern about accidents.

How should we make decisions when we're uncertain about what we ought, morally, to do? Decision-making in the face of fundamental moral uncertainty is underexplored terrain: MacAskill, Bykvist, and Ord argue that there are distinctive norms by which it is governed, and which depend on the nature of one's moral beliefs.

This paper reflects on the various possible nuclear power production methods from an ethical perspective. The production and consumption of nuclear power give rise to the problem of intergenerational justice; in other words, we are depleting a nonrenewable resource in the form of uranium while the radiotoxic waste that is generated carries very long-term potential burdens. I argue that the morally desirable option should therefore be to seek to safeguard the interests of future generations. The present generation has at least (...) two duties with regard to posterity: not to jeopardize the safety and security of future generations or impose any harm upon them and to sustain future well-being insofar as that is possible with the available energy resources. These duties are presented as pluralist prima facie duties thus implying that they could well be overruled by morally more compelling duties. If we are unable to fulfill both these prima facie duties simultaneously, it should be particularly the duty not to impose harm on posterity that should be the leading incentive behind nuclear power production. This supports the arguments in favor of the introduction of a new fuel cycle that can substantially reduce the waste lifetime and therefore also potential future burdens. However, the further development and application of this scientifically proven but not yet industrialized fuel cycle give rise to additional burdens for contemporaries. This paper examines the extent of the moral stringency of the no harm duty sought for situations in which future interest should guide us in our choosing of a certain technology. (shrink)
