Abstract

Two questions are central to the ethics of geoengineering. The justificatory question asks ‘Under what future conditions might geoengineering become justified?’, where the conditions to be considered include, for example, the threat to be confronted, the background circumstances, the governance mechanisms, individual protections, compensation provisions, and so on. The contextual question asks ‘What is the ethical context of the push toward geoengineering, and what are its implications?’ Unfortunately, early discussions of geoengineering often marginalize both questions because they tend to focus on arguments from emergency that illegitimately brush them aside. One sign of this is that some emergency arguments are ethically short-sighted, and morally schizophrenic. In this paper, I illustrate this problem by appeal to two abstract examples. Although both are extreme and idealized, even the imperfect analogies provide reasons for concern about our current predicament. Ethically serious discussion of geoengineering should confront such worries, rather than hide behind overly simplistic appeals to moral emergency. As Michael Stocker puts it in his seminal discussion of moral schizophrenia, “to refuse to do so bespeaks a malady of the spirit.”
