Geoengineering as a technological intervention to avert the dangerous climate change has been on the table at least since 2006. The global outreach of the technology exercised in a non-encapsulated system, the concerns with unprecedented levels and scales of impact and the overarching interdisciplinarity of the project make the geoengineering debate ethically quite relevant and complex. This paper explores the ethical desirability of geoengineering from an overall review of the existing literature on the ethics of geoengineering. It identifies the relevant (...) literature on the ethics of geoengineering by employing a standard methodology. Based on various framing of the major ethical arguments and their subsets, the results section presents the opportunities and challenges at stake in geoengineering from an ethical point of view. The discussion section takes a keen interest in identifying the evolving dynamics of the debate, the grey areas of the debate, with underdeveloped arguments being brought to the foreground and in highlighting the arguments that are likely to emerge in the future as key contenders. It observes the semantic diversity and ethical ambiguity, the academic lop-sidedness of the debate, missing contextual setting, need for interdisciplinary approaches, public engagement, and region-specific assessment of ethical issues. Recommendations are made to provide a useful platform for the second generation of geoengineering ethicists to help advance the debate to more decisive domains with the required clarity and caution.

Written both for general readers and college students, Dialogues on Climate Justice provides an engaging philosophical introduction to climate justice, and should be of interest to anyone wanting to think seriously about the climate crisis. -/- The story follows the life and conversations of Hope, a fictional protagonist whose life is shaped by a terrifyingly real problem: climate change. From the election of Donald Trump in 2016 until the 2060s, the book documents Hope’s discussions with a diverse cast of characters. (...) As she ages, her conversations move from establishing the nature of the problem, to engaging with climate skepticism, to exploring her own climate responsibilities, through managing contentious international negotiations, to considering big technological fixes, and finally, as an older woman, to reflecting with her granddaughter on what one generation owes another. Following a philosophical tradition established by Plato more than two thousand years ago, these dialogues are not only philosophically substantive and carefully argued, but also distinctly human. The differing perspectives on display mirror those involved in real-world climate dialogues going on today. (shrink)

Recently, research into the possibilities of developing solar radiation management and other geoengineering technologies has gained new momentum. Just last year, Cambridge University announced the opening of a “Centre for Climate Repair” as part of the university’s Carbon Neutral Futures Initiative. Recent modeling work gives hope that SRM could confer more benefits than previously thought. But opposition to even conducting research into SRM remains strong. I use the case study of SRM to develop a framework, based on a theorem by (...) I.J. Good, for thinking about the benefits and costs of acquiring new evidence and for thinking about the conditions under which new evidence could be harmful. I argue that the expected benefits of supporting public research in SRM technologies outweigh the expected costs and harms. (shrink)
