Some philosophers have recently argued that decision-makers ought to take normative uncertainty into account in their decisionmaking. These philosophers argue that, just as it is plausible that we should maximize expected value under empirical uncertainty, it is plausible that we should maximize expected choice-worthiness under normative uncertainty. However, such an approach faces two serious problems: how to deal with merely ordinal theories, which do not give sense to the idea of magnitudes of choice-worthiness; and how, even when theories do give (...) sense to magnitudes of choice-worthiness, to compare magnitudes of choice-worthiness across different theories. Some critics have suggested that these problems are fatal to the project of developing a normative account of decision-making under normative uncertainty. The primary purpose of this article is to show that this is not the case. To this end, I develop an analogy between decision-making under normative uncertainty and the problem of social choice, and then argue that the Borda Rule provides the best way of making decisions in the face of merely ordinal theories and intertheoretic incomparability.

Geoengineering has been broadly and helpfully defined as “the intentional manipulation of the earth's climate to counteract anthropogenic climate change or its warming effects” (Corner and Pidgeon , 26). Although there exists a rapidly growing literature on the ethics of geoengineering, very little has been written about its gender dimensions. The authors consider four contexts in which geoengineering appears to have important gender dimensions: (1) the demographics of those pushing the current agenda, (2) the overall vision of control it involves, (...) (3) the design of the particular technologies, and (4) whom geoengineering will most affect and benefit. After detailing these four gender dimensions, we consider three ways in which the geoengineering discourse could be enriched if it became more sensitive to issues of gender. These include increasing the focus on the concrete other, recognizing the socially transformative potential of geoengineering technologies, and engaging in value-sensitive design. Although ultimately remaining agnostic on the desirability of geoengineering, the paper brings gender considerations into a discussion from which they have been conspicuously absent. (shrink)

Climate change presents us with a problem of intergenerational justice. While any costs associated with climate change mitigation measures will have to be borne by the world’s present generation, the main beneficiaries of mitigation measures will be future generations. This raises the question to what extent present generations have a responsibility to shoulder these costs. One influential approach for addressing this question is to appeal to neo-classical economic cost–benefit analyses and so-called economy-climate “integrated assessment models” to determine what course of (...) action a principle of intergenerational welfare maximization would require of us. I critically examine a range of problems for this approach. First, integrated assessment models face a problem of underdetermination and induction: They are very sensitive to a number of highly conjectural assumptions about economic responses to a temperature and climate regime, for which we have no empirical evidence. Second, they involve several simplifying assumptions which cannot be justified empirically. And third, some of the assumptions underlying the construction of economic models are intrinsically normative assumptions that reflect value judgments of the modeler. I conclude that, while integrated assessment models may play a useful role as “toy models,” their use as tools for policy optimization is highly problematic. (shrink)

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

In part one, I identify the core logical structure of the precautionary principle and distinguish it from the various key concepts that appear in the many different formulations of the principle. I survey these concepts and suggest a program of further conceptual analysis. In part two, I examine a particular version of the precautionary principle dubbed “the catastrophe principle” and criticize it in light of its similarities to the principle at work in Pascal’s Wager. I conclude with some suggestions for (...) advocates of the precautionary principle who wish their formulation to avoid the pitfalls confronting the catastrophe principle. (shrink)

This article brings a new perspective to the ethical debate on geoengineering through stratospheric aerosol injection (SAI), incorporating the emerging techno-moral change scholarship into the discussion surrounding sustainability. The techno-moral change approach can help us understand different ways in which technology might shape society. First, it helps highlight how values and norms are interrelated. Second, it shows that techno-moral change can happen even if the technology is in no way realized. Through the introduction of two techno-moral vignettes, two diametrically opposed (...) ways in which SAI forces us to rethink sustainability and our relationship with nature are suggested. SAI could lead to a situation of entrenchment, wherein sustainability as a norm is undermined, or transformation where the necessity of acting according to sustainability is highlighted. (shrink)

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.

With the lack of progress there has been so far on climate change, some have begun researching the potential of geoengineering to allay future climatic harms. However, others contend that such research should be abandoned. One of the most‐cited reasons as to why research into geoengineering should be abandoned is the idea that such research sits at the top of slippery slope. The Slippery Slope Argument warns that even mere research into geoengineering will create institutional momentum, ultimately leading to the (...) deployment of a technology that is untested and perhaps morally objectionable. This article clearly lays out the Slippery Slope Argument against geoengineering research and analyses its premises. I claim that both the empirical premise – that research will inevitably lead to deployment – and the normative premise – that we have decisive moral reasons to avoid deployment – are questionable. The main conclusion of the article is that while we should be cognizant of the potential for research to lead to undesirable deployment scenarios, engaging in research need not necessarily lead inexorably to deployment. While insufficient to ground a moratorium on research, the Slippery Slope Argument points to the need for regulation and oversight in order to prevent undesirable deployment. (shrink)

In recent years the idea of geoengineering climate has begun to attract increasing attention. Although there was some discussion of manipulating regional climates throughout the l970s and l980s. the discussion was largely dormant. What has reawakened the conversation is the possibility that Earth may be undergoing a greenhouse-induced global wamring, and the paucity of serious measures that have been taken to Prevent it. ln this paper Iassess the ethical acceptability of ICC, based on my impressions of the conversation that is (...) now taking place. Rather than offering a dispassionate analysis, I argue for a point of view. I propose a set of conditions that must be satisfied for an ICC project to be morally permissible and conclude that these conditions are not now satisfied. However, research on ICC should go forward.. (shrink)

“[T]he Precautionary Principle still has neither a commonly accepted definition nor a set of criteria to guide its implementation. “There is”, Freestone … cogently observes, “a certain paradox in the widespread and rapid adoption of the Precautionary Principle”: While it is applauded as a “good thing”, no one is quite sure about what it really means or how it might be..

Global-scale solar geoengineering raises critical ethical questions, including questions of distributive, procedural, and intergenerational justice. Although geoengineering is sometimes framed as a response to injustice, insofar as it might benefit those most vulnerable to climate-related harms, geoengineering also has the potential to exacerbate climate injustice, especially if control of research, governance, and potential plans for deployment remains concentrated in the hands of a few. The scope and scale of solar geoengineering, the diverse concerns it raises, and the lack of consensus (...) surrounding it pose particular challenges for justice. I argue that addressing these challenges requires an inclusive, dialogical approach that takes seriously diverse perspectives, particularly the perspectives of those who are most affected by climate change and those who have had the least voice in decisions surrounding it. The concept of recognition––as developed in the work of Nancy Fraser, David Schlosberg, and others––offers a normative ground for this approach and can help guide the development of institutions and practices directed toward geoengineering justice.

Neither traditional philosophy nor current applied ethics seem able to cope adequately with the highly dynamic character of our modern technological culture. This is because they have insufficient insight into the moral significance of technological artifacts and systems. Here, much can be learned from recent science and technology studies. They have opened up the black box of technological developments and have revealed the intimate intertwinement of technology and society in minute detail. However, while applied ethics is characterized by a certain (...) “technology blindness,” the most influential approaches within STS show a “normative deficit” and display an agnostic or even antagonistic attitude toward ethics. To repair the blind spots of both applied ethics and STS,the authors sketch the contours of a pragmatist approach. They will explore the tasks and tools of a pragmatist ethics and pay special attention to the exploration of future worlds disclosed and shaped by technology and the management of deep value conflicts inherent to a pluralist society.

ABSTRACTThis article offers a constructive critique of the Oxford Principles for the governance of geoengineering and proposes an alternative set of principles, the Tollgate Principles, based on that critique. Our main concern is that, despite their many merits, the Oxford Principles remain largely instrumental and dominated by procedural considerations; therefore, they fail to lay the groundwork sufficiently for the more substantive ethical debate that is needed. The article aims to address this gap by making explicit many of the important ethical (...) questions lurking in the background, especially around values such as justice, respect and legitimacy.

We are living in a climate of risk. Our way of life imposes risks on ourselves and others. We are causing climatic changes that have the potential to change radically the conditions under which both we - the presentgeneration - and future generations will live. While we are now quite certain that climate change is happening, we are unsure of exactly what will happen and when, given different emissions and policy scenarios. We are therefore in a position where we must (...) decide what to do about the risks climate change threatens in the face of a range of uncertainties In this book, Lauren Hartzell-Nichols provides guidance in the face of this uncertainty by offering an in-depth discussion of how and why we ought to take a precautionary approach to climate policy, namely by appeal to a Catastrophic Precautionary Principle and Catastrophic Precautionary Decision-Making Framework. By examining the way in which climate change is harmful, Hartzell-Nichols shows how precaution does have a meaningful role to play in moving climate policy forward if we reconsider what precaution is about before too quickly appealing to precaution as a reason or justification for action. A Climate of Risk takes a philosophically grounded, interdisciplinary approach that will appeal to a broad scholarly and policy-oriented audience. Hartzell-Nichols's reinterpretation of the precautionary principle enables precaution to be more effectively leveraged as a driver of action on climate change. (shrink)

Solar radiation management is a form of geoengineering that involves the intentional manipulation of solar radiation with the aim of reducing global average temperature. This paper explores what precaution implies about the status of solar radiation management. It is argued that any form of solar radiation management that poses threats of catastrophe cannot constitute an appropriate precautionary measure against another threat of catastrophe, namely climate change. Research of solar radiation management is appropriate on a precautionary view only insofar as such (...) research aims to identify whether any forms of solar radiation management could be implemented without creating new or exacerbating existing threats of catastrophe.
