Abstract

Radical forms of geoengineering, such as stratospheric sulfate injection (SSI), raise serious concerns about justice and the plight of the most vulnerable. However, these are sometimes dismissed on the basis of a challenge: “What if, in the face of catastrophic impacts, the most vulnerable countries initiate geoengineering themselves, or beg the richer, more technically sophisticated countries to do it? Wouldn’t geoengineering then be ethically permissible? Who could refuse them?” As a US tech billionaire put it, “Frankly, the Maldives could say, ‘F--- you all—we want to stay alive’. Would you blame them? Wouldn’t any reasonable country do the same?” Such questions are intended to be rhetorical: it is assumed simply to be obvious that the appeals of the desperate would justify radical geoengineering. Moreover, the framing suggests that other nations would have strong moral reasons either to respect intervention by the desperate, or even to aid them by deploying themselves. Sometimes such arguments are also used to justify accelerating research on geoengineering now. If the desperate might attempt geoengineering, it is said, we should work out how best to do it, so as to assist them through advice. In general, the overriding thought is that the threat of catastrophe coupled with the plight of vulnerable populations provides most of the justification needed for the wider pursuit of a geoengineering agenda. Desperation becomes a trump card in the policy discourse. In this article, I argue that the desperation argument misses much of what is at stake, ethically speaking, in geoengineering policy. I focus on two further questions. The more obvious—the justificatory question—asks “under what conditions would geoengineering become justified?”, where the conditions to be considered would include, for example, the threat to be confronted, the governance mechanisms, the individual protections to be provided, the compensation provisions to be made, and so on. The less obvious question is the contextual question: “What is the ethical context within which geoengineering is likely to occur, and what difference does this make to our analysis of it?” (Gardiner 2013). In light of this distinction, I argue for two claims. First, on neither of the two most obvious interpretations of it does the desperation argument clearly justify the pursuit of geoengineering. Indeed, it may even count against such pursuit. Second, in any case, the context in which SSI is actually being pursued reveals more about the live threats and ethical import of geoengineering. For example, to push the most vulnerable to the point where they feel forced to accept pronounced subjugation to those who have made them desperate is a morally horrifying prospect which we have strong ethical reason to avoid. Such possibilities should not be concealed behind the superficial bravado of “f--- you all” and “what any reasonable country would do.” None of this implies that ethical geoengineering is impossible. However, it does suggest that geoengineering is morally complex in ways unappreciated by simple appeals to desperation.
