Climate change has become one of the most pressing problems that can threaten the existence and development of humans around the globe. Almost all climate scientists have agreed that climate change is happening and is caused mainly by greenhouse gas emissions induced by anthropogenic activities. However, some groups still deny this fact or do not believe that climate change results from human activities. This article examines climate change denialism and its skeptical arguments, as well as (...) the roles of scientists and science communication in addressing the issues. Through this article, we call for the active participation of scientists in science communication activities with the public, the initiation of new science communication sectors specified for climate change, and more attention to social sciences and humanities in addressing climate change issues.

Climate change poses grave threats to many people, including the most vulnerable. This prompts the question of who should bear the burden of combating ?dangerous? climate change. Many appeal to the Polluter Pays Principle. I argue that it should play an important role in any adequate analysis of the responsibility to combat climate change, but suggest that it suffers from three limitations and that it needs to be revised. I then consider the Ability to Pay Principle and (...) consider four objections to this principle. I suggest that, when suitably modified, it can supplement the Polluter Pays Principle. (shrink)

Several philosophers claim that the greenhouse gas emissions from actions like a Sunday drive are so miniscule that they will make no difference whatsoever with regard to anthropogenic global climate change (AGCC) and its expected harms. This paper argues that this claim of individual causal inefficacy is false. First, if AGCC is not reducible at least in part to ordinary actions, then the cause would have to be a metaphysically odd emergent entity. Second, a plausible (dis-)utility calculation reveals that (...) such actions have a not-insignificant amount of expected harm. One upshot is that the near-exclusive focus in the literature on AGCC as a collective action problem is too restricted. The paper also provides several moral psychological explanations of why it is so difficult to comprehend individual responsibility with regard to global phenomena, including a reappraisal of Thomas Nagel’s view of the absurd.

Climate change is projected to have very severe impacts on future generations. Given this, any adequate response to it has to consider the nature of our obligations to future generations. This paper seeks to do that and to relate this to the way that inter-generational justice is often framed by economic analyses of climate change. To do this the paper considers three kinds of considerations that, it has been argued, should guide the kinds of actions that one generation (...) should take if it is to treat both current and future people equitably. In particular it examines the case for what has been termed pure time discounting, growth discounting and opportunity cost discounting; and it assesses their implications for climate policy. It argues that none of these support the claims of those who think they give us reason to delay aggressive mitigation policies. It also finds, however, that the second kind of argument can, in certain circumstances, provide support for passing on some of the costs of mitigation to future generations. (shrink)

This essay examines the relationship between climate change and human rights. It argues that climate change is unjust, in part, because it jeopardizes several core rights – including the right to life, the right to food and the right to health. It then argues that adopting a human rights framework has six implications for climate policies. To give some examples, it argues that this helps us to understand the concept of “dangerous anthropogenic interference” (UNFCCC, Article 2). In (...) addition to this, it argues that if we adopt a human rights framework then any climate policies should also honour human rights, and so mitigation policies, for example, should not compromise people’s enjoyment of their human rights. A third implication, I argue, is that in addition to duties of mitigation and adaptation there will also be – if rights are violated – duties of compensation too. (shrink)

Climate change is one of the most important issues we are currently facing. There are many ways in which states can fight climate change. Some of them involve interfering with citizens’ personal lives. The question of whether such interference is justified is under-explored in philosophy. This paper focuses on a specific aspect of people’s personal lives, namely their informational privacy. It discusses the question of whether, given certain empirical assumptions, it is proportional of the state to risk its (...) citizens’ privacy or to risk infringing its citizens’ right to privacy to fight climate change. The main claim this paper argues for is that if fighting climate change and protecting our privacy conflict, we have good reason to fight climate change rather than protect our privacy. (shrink)

In this paper I make the following claims. In order to see anthropogenic climate change as clearly involving moral wrongs and global injustices, we will have to revise some central concepts in these domains. Moreover, climate change threatens another value that cannot easily be taken up by concerns of global justice or moral responsibility.

Understanding climate change is becoming an urgent requirement for those in education. The normative values of education have long been closely aligned with the global, modernised world. The industrial model has underpinned the hidden and overt curriculum. Increasingly though, a new eco-centric orientation to economics, technology, and social organisation is beginning to shape up the post-carbon world. Unless education is up to date with the issues of climate change, the estate of education will be unable to meet its (...) task of knowledge transfer. This paper covers the basic science and ethical policy debates, and begins to outline the questions that will necessarily entangle education as we orientate ourselves to the new world that is upon us.

Tackling climate change is one of the most demanding challenges of humanity in the 21st century. Still, the efforts to mitigate the current environmental crisis do not seem enough to deal with the increased existential risks for the human and other species. Persson and Savulescu have proposed that our evolutionarily forged moral psychology is one of the impediments to facing as enormous a problem as global warming. They suggested that if we want to address properly some of the most (...) pressing problems that cause catastrophic harm to our existence, we should enhance our moral behavior by biomedical means. The objective of this paper is, precisely, to reflect on whether a Moral Bio-Enhancement (henceforth MBE) program would be a viable option to confront the climate emergency. To meet this goal, I will propose the Ultimate Mostropic (hereafter UM) thought experiment, a hypothetical situation where we have already discovered the UM, an available, safe (without any deleterious secondary effects), extremely cheap and effective pill to enhance our cognitive, affective and motivational abilities related to morality. After briefly presenting the main argument of Persson and Savulescu regarding MBE and climate change, I will point out some of the difficulties that make MBE a daunting but exciting philosophical and scientific debate. In order to overcome these complications, I will describe the UM thought experiment, which involves two scenarios of the MBE program: (a) the state-driven, compulsory and universal enterprise, and (b) the initiative of voluntary individuals. I will show that the shortcomings of MBE programs through the UM in both scenarios make Persson and Savulescu’s proposal a not appealing pathway to mitigate climate change. In the final section, I will suggest that an inaccurate attribution of responsibilities underlies their proposal and that the collective inaction problem should be redirected primarily through a reinforcement of the political nature of the solutions.

This paper examines what agents should do when others fail to comply with their responsibilities to prevent dangerous climate change. It distinguishes between six different possible responses to noncompliance. These include what I term (1) 'target modification' (watering down the extent to which we seek to prevent climate change), (2) ‘responsibility reallocation’ (reassigning responsibilities to other duty bearers), (3) ‘burden shifting I’ (allowing duty bearers to implement policies which impose unjust burdens on others, (4) 'burden shifting II’ (allowing (...) some to protect peoples rights in ways which impose otherwise unjustified burdens on the duty bearers, (5) 'compromising moral ideals' (permitting agents to compromise non-justice ideals that they are otherwise bound by); and (6) ‘promoting compliance (implementing policies and creating institutions which reduce noncompliance). It concludes by outlining a methodological framework for evaluating these options, and by setting out my tentative and provisional evaluation of which responses are the least bad. (shrink)

The Intergovernmental Panel on Climate Change has developed a novel framework for assessing and communicating uncertainty in the findings published in their periodic assessment reports. But how should these uncertainty assessments inform decisions? We take a formal decision-making perspective to investigate how scientific input formulated in the IPCC’s novel framework might inform decisions in a principled way through a normative decision model.

If climate change represents a severe threat to humankind, why then is response to it characterized by inaction at all levels? The authors argue there are two complementary explanations for the lack of motivation. First, our moral judgment system appears to be unable to identify climate change as an important moral problem and there are pervasive doubts about the agency of individuals. This explanation, however, is incomplete: Individual emitters can effectively be held morally responsible for their luxury emissions. (...) Second, doubts about individual agency have become overly emphasized and fail to convincingly exonerate individuals from responsibility. This book extends the second explanation for the motivational gap, namely that the arguments for the lack of individual agency do in fact correspond to mechanisms of moral disengagement. The use of these mechanisms enables consumption elites to maintain their consumptive lifestyles without having to accept moral responsibility for their luxury emissions. (shrink)

Climate Change and the Moral Agent examines the moral foundations of climate change and makes a case for collective action on climate change by appealing to moralized collective self-interest, collective ability to aid, and an expanded understanding of collective responsibility for harm.

Although actions of individuals do contribute to climate change, the question whether or not they, too, are morally obligated to reduce the GHG emissions in their responsibility has not yet been addressed sufficiently. First, I discuss prominent objections to such a duty. I argue that whether individuals ought to reduce their emissions depends on whether or not they exceed their fair share of emission rights. In a next step I discuss several proposals for establishing fair shares and also take (...) practical considerations into account. I conclude that individuals should not always be obliged to reduce their emissions to what is their fair share for they may depend on carbon-intensive structures. Instead, they have a Kantian imperfect duty to reduce their emissions ‘as far as can reasonably be demanded of them’. In addition, they should press governments to introduce proper regulation. At the end, I further specify both duties. (shrink)

Under the UNHCR definition of a refugee, set out in the 1967 Protocol Relating to the Status of Refugees, people fleeing their homes because of natural disasters or other environmental problems do not qualify for refugee status and the protection that come from such status. In a recent paper, "Who Are Refugees?", I defended the essentials of the UNHCR definition on the grounds that refugee status and protection is best reserved for people who can only be helped by granting them (...) refuge in a safe state for an indefinite period of time, and argued that this does not include most people fleeing from natural disasters. This claim is most strongly challenged by possibility of displacement from climate change. In this paper I will explore to what degree the logic of the refugee convention, as set out in my earlier paper, can and should be extended to those fleeing the results of climate change, and will argue that the logic of the refugee convention tells in favor of extending refugee protection to a portion of those who must flee their homes because of climate-change related environmental problems.

Anthropogenic climate change is a global process affecting the lives and well-being of millions of people now and countless number of people in the future. For humans, the consequences may include significant threats to food security globally and regionally, increased risks of from food-borne and water-borne as well as vector-borne diseases, increased displacement of people due migrations, increased risks of violent conflicts, slowed economic growth and poverty eradication, and the creation of new poverty traps. Principles of justice are statements (...) of what persons are owed either by others or by institutions and policies. Climate change gives rise to many concern of justice. This article briefly summarizes some of the most important of these, including claims to have climate change mitigated, claims regarding the sharing of the costs of climate change mitigation, claims for investment into adaptation, and claims to be compensated.

Obstacles to achieving a global climate treaty include disagreements about questions of justice raised by the UNFCCC's principle that countries should respond to climate change by taking cooperative action "in accordance with their common but differentiated responsibilities and respective capabilities and their social and economic conditions". Aiming to circumvent such disagreements, Climate Change Justice authors Eric Posner and David Weisbach argue against shaping treaty proposals according to requirements of either distributive or corrective justice. The USA's climate (...) envoy, Todd Stern, takes a similar position. In this article I explain the practical and theoretical drawbacks of Posner & Weisbach's welfarist perspective and propose an alternative. I show that their arguments fail to rule out John Rawls' non-utilitarian, political conception of international justice and human rights, the Law of Peoples. On this basis I develop a conception of climate justice that highlights implications of some of Rawls' principles and adds a principle for determining fair shares of climate -treaty-related benefits and burdens. I propose this conception as a moral framework for negotiating a treaty that would promote human welfare consistently with requirements of justice, and I argue that a treaty proposal satisfying these requirements could best satisfy Posner & Weisbach's own feasibility criteria.

There are a number of cases where, collectively, groups cause harm, and yet no single individual’s contribution to the collective makes any difference to the amount of harm that is caused. For instance, though human activity is collectively causing climate change, my individual greenhouse gas emissions are neither necessary nor sufficient for any harm that results from climate change. Some (e.g., Sinnott-Armstrong) take this to indicate that there is no individual moral obligation to reduce emissions. There is a (...) collective action problem here, to which I offer a solution. My solution rests on an argument for a (sometimes) bare moral difference between intending harm and foreseeing with near certainty that harm will result as an unintended side-effect of one’s action. I conclude that we have a moral obligation to reduce our individual emissions; and, more broadly, an obligation to not participate in many other harmful group activities (e.g., factory-farming). (shrink)

Environmental ethicists have not reached a consensus about whether or not individuals who contribute to climate change have a moral obligation to reduce their personal greenhouse gas emissions. In this paper, I side with those who think that such individuals do have such an obligation by appealing to the concept of integrity. I argue that adopting a political commitment to work toward a collective solution to climate change—a commitment we all ought to share—requires also adopting a personal commitment (...) to reduce one’s emissions. On these grounds, individuals who contribute to climate change have a prima facie moral duty to lower their personal greenhouse gas emissions. After presenting this argument and supporting each of its premises, I defend it from two major lines of objection: skepticism about integrity’s status as a virtue and concerns that the resulting moral duty would be too demanding to be morally required. I then consider the role that an appeal to integrity could play in galvanizing the American public to take personal and political action regarding climate change. (shrink)

Long before the phrases “climate change” and “butterfly effect” were incorporated into the mainstream literature, these phrases appeared in an appropriate context almost verbatim in the first Chapter of a book entitled “The Emigrant” published in the mid-nineteenth century by Sir Francis Bond Head. Head was Upper Canada’s sixth Lieutenant Governor under King George IV and Queen Victoria. Head claimed that forest wildfires were “changing the climate” of North America as manifested in a warming effect “on the thermometer”. (...) In that author’s account, these fires were provoked by First Nations to create fly-free zones meant to attract game that they could then hunt more readily. Head used language such as “swarms of little flies, strange as it may sound, are, and for many years have been, most materially altering the climate…” which is remarkably reminiscent of E. N. Lorenz’s “butterfly effect” of the theory of chaotic dynamical systems. The historical context and the rationales that may have led Head to use this contemporary environmental language in a proper context are briefly discussed. (shrink)

Climate change poses a serious problem for established ethical theories. There is no dearth of literature on the subject of climate ethics that break down the complexity of the issue, thereby enabling one to arrive at partial conclusions such as: 'historical justice demands us to do this...' or 'intergenerational justice demands us to do that...'. In contrast, this article attempts to face up to this complexity, that is: to end with a synthesis of the arguments into what can (...) be considered to be the most reasonable and fairest approach to the politics of climate change on a global scale. A significant part of the paper is devoted to the questions whether or not a) historical emissions and b) population changes are relevant to how emissions rights should be distributed. I discuss the merits and drawbacks of each perspective and briefly outline the normative justifications. (shrink)

Climate change is one of the most pressing issues facing humanity and has become an area of growing focus in Business & Society. Looking back and reviewing climate change discussion within this journal highlights the importance of time and space in addressing the climate crisis. Looking forward, we extend existing research by theorizing and politicizing the co-implication of time and space through the concept of “space-time.” To illustrate this, we employ the logical structure of “the trace” to (...) advance business and society scholarship on climate change by shifting the focus to a place-bound emphasis on climate impacts and directing scholarship toward climate change’s temporal markers and material effects. By operationalizing “the trace,” we contribute to Business & Society debates in three ways: reimagining complex stakeholder relations, advancing a performative understanding of climate risk, and foregrounding planetary systems and the physical environment.

Climate change is one of the most urgent global problems that we are facing today. The causes are well understood and many solutions have been proposed. However, so far none of them have been successful. Ingmar Persson and Julian Savulescu have argued that this is because our moral psychology is ill-equipped to deal with global problems such as this one. They propose that in order to successfully mitigate climate change we should morally enhance ourselves. In this chapter we (...) look into their proposal to see whether moral enhancement is indeed a viable solution to the climate crisis. We conclude that due to various theoretical and practical problems it is most likely not. (shrink)

Climate change harms health and damages and diminishes environmental resources. Gradually it will cause health systems to reduce services, standards of care, and opportunities to express patient autonomy. Prominent public health organizations are responding with preparedness, mitigation, and educational programs. The design and effectiveness of these programs, and of similar programs in other sectors, would be enhanced by greater understanding of the values and tradeoffs associated with activities and public policies that drive climate change. Bioethics could generate such (...) understanding by exposing the harms and benefits in different cultural, socioeconomic, and geographic contexts, and through interdisciplinary risk assessments. Climate change is a bioethics problem because it harms everyone and involves health, values, and responsibilities. This article initiates dialog about the responsibility of bioethics to promote transparency and understanding of the social values and conflicts associated with climate change, and the actions and public policies that allow climate change to worsen.

This chapter investigates the varying stances of the great religions on climate change, their historical backgrounds, and reasons for the diversity to be found among their recent statements. It responds to criticisms of the stewardship interpretation of Christianity and considers the contrasting view that the roots of contemporary ecological problems including that of climate change lie in religious acquiescence in early modern economic individualism. The degree of lasting impact of these stances is held to depend on the attitudes (...) of the different religions to structural change and reform. (shrink)

Despite recognizing many adverse impacts, the climate science literature has had little to say about the conditions under which climate change might threaten civilization. Discussions of the mechanisms whereby climate change might cause the collapse of current civilizations has mostly been the province of journalists, philosophers, and novelists. We propose that this situation should change. In this opinion piece, we call for treating the mechanisms and uncertainties associated with climate collapse as a critically important topic for (...) scientific inquiry. Doing so requires clarifying what "civilization collapse" means and explaining how it connects to topics addressed by climate scientists. [Open access] -/- . (shrink)

Climate change and justice are so closely associated that many people take it for granted that a global climate treaty should--indeed, must--directly address both issues together. But, in fact, this would be a serious mistake, one that, by dooming effective international limits on greenhouse gases, would actually make the world's poor and developing nations far worse off. This is the provocative and original argument of Climate Change Justice. Eric Posner and David Weisbach strongly favor both a (...) class='Hi'>climate change agreement and efforts to improve economic justice. But they make a powerful case that the best--and possibly only--way to get an effective climate treaty is to exclude measures designed to redistribute wealth or address historical wrongs against underdeveloped countries. In clear language, Climate Change Justice proposes four basic principles for designing the only kind of climate treaty that will work--a forward-looking agreement that requires every country to make greenhouse--gas reductions but still makes every country better off in its own view. This kind of treaty has the best chance of actually controlling climate change and improving the welfare of people around the world. (shrink)

What kinds of issues does the global crisis of climate change present to aesthetics, and how will they challenge the field to respond? This paper argues that a new research agenda is needed for aesthetics with respect to global climate change (GCC) and outlines a set of foundational issues which are especially pressing: (1) attention to environments that have been neglected by philosophers, for example, the cryosphere and aerosphere; (2) negative aesthetics of environment, in order to grasp aesthetic (...) experiences, meanings, and dis/values in light of the catastrophic effects of GCC; (3) bringing intergenerational thinking into aesthetics through concepts of temporality and ‘future aesthetics’ (4) understanding the relationship between aesthetic and ethical values as they arise in regard to GCC.

In this paper I engage interdisciplinary conversation on inaction as the dominant response to climate change, and develop an analysis of the specific phenomenon of complacency through a critical-feminist lens. I suggest that Chris Cuomo's discussion of the “insufficiency” problem and Susan Sherwin's call for a “public ethics” jointly point toward particularly promising harm-reduction strategies. I draw upon and extend their work by arguing that extant philosophical accounts of complacency are inadequate to the task of sorting out what it (...) means to be complacent on climate change. I offer a sketch for an alternative account, which I take to be a start in the direction of mapping out a diverse array of “motivational vices” that need to be named, grappled with, and remedied.

Climate change is undeniably a global problem, but the situation is especially dire for countries whose territory is comprised entirely or primarily of low-lying land. While geoengineering might offer an opportunity to protect these states, international consensus on the particulars of any geoengineering proposal seems unlikely. To consider the moral complexities created by unilateral deploy- ment of geoengineering technologies, we turn to a moral convention with a rich history of assessing interference in the sovereign affairs of foreign states: the (...) just war tradition. We argue that the just war framework demonstrates that, for these nations, geoengineering offers a justified form of self-defense from an unwar- ranted, albeit unintentional, aggression. This startling result places our own car- bon-emitting activities in a stark new light: in perpetrating climate change, we are, in fact, waging war on the most vulnerable. (shrink)

This chapter concerns the nature of our obligations as individuals when it comes to our emissions-producing activities and climate change. The first half of the chapter argues that the popular ‘expected utility’ approach to this question faces a problematic dilemma: either it gives skeptical verdicts, saying that there are no such obligations, or it yields implausibly strong verdicts. The second half of the chapter diagnoses the problem. It is argued that the dilemma arises from a very general feature of (...) the view, and thus is shared by other views as well. The chapter then discusses what an account of our individual obligations needs to look like if it is to avoid the dilemma. Finally, the discussion is extended beyond climate change to other collective impact contexts. (shrink)

Walter Sinnott-Armstrong argues, on the relationship between individual emissions and climate change, that “we cannot claim to know that it is morally wrong to drive a gas guzzler just for fun” or engage in other inessential emissions-producing individual activities. His concern is not uncertainty about the phenomenon of climate change, nor about human contribution to it. Rather, on Sinnott-Armstrong’s analysis the claim of individual moral responsibility for emissions must be grounded in a defensible moral principle, yet no principle (...) withstands scrutiny. I argue thatthe moral significance of individual emissions is obscured by this critique. I offer a moral principle, the threshold-contribution principle, capable of withstanding Sinnott-Armstrong’s criticisms while also plausibly explaining what’s wrong with gas-guzzling joyrides and other gratuitous emissions-producing individual acts.

Given that mitigating climate change is a large-scale global issue, what obligations do individuals have to lower their personal carbon emissions? I survey recent suggestions by Walter Sinnott-Armstrong and Dale Jamieson and offer models for thinking about their respective approaches. I then present a third model based on the notion of structural violence. While the three models are not mutually incompatible, each one suggests a different focus for mitigating climate change. In the end, I agree with Sinnott-Armstrong that (...) people have limited moral obligations to directly lower personal emissions, but I offer different reasons for this conclusion, namely that the structural arrangements of our lives place a limit on how much individuals can restrict their own emissions. Thus, individuals should focus their efforts on changing the systems instead (e.g., the design of cities, laws and regulation, etc.), which will lead to lower emissions on a larger scale. (shrink)

Two kinds of philosophical questions are raised by the current public debate about climate change; epistemic questions (Whom should I believe? Is climate science a genuine science?), and ethical questions (Who should bear the burden? Must I sacrifice if others do not?). Although the former have been central to this debate, professional philosophers have dealt almost exclusively with the latter. This book is the first to address both the epistemic and ethical questions raised by the climate change (...) debate and examine the relationship between them. (shrink)

What does it matter if the climate changes? This kind of question does not admit of a scientific answer. Natural science can tell us what some of its biophysical effects are likely to be; social scientists can estimate what consequences such effects could have for human lives and livelihoods. But how should we respond? The question is, at root, about how we think we should live—and different people have myriad different ideas about this. The distinctive task of ethics is (...) to bring some clarity and order to these ideas. (shrink)

Public sentiment regarding climate change in the United States is starkly divided, with the Republicans and Democrats holding markedly different views. Given the inherent connection between the water crisis and climate change, this research aimed to investigate the interplay between the residents’ beliefs about the impact of climate change on water supply unpredictability, their political identity, and their willingness to adopt direct and indirect potable water reuse. The Bayesian Mindsponge Framework (BMF) analytics was conducted on a dataset (...) of 1,831 water users in the arid region of Albuquerque, New Mexico. The findings reveal a complicated interplay among examined factors. Specifically, we discovered a positive association between the belief in the impacts of climate change and the willingness to adopt potable water reuse among non-Republican water users. In contrast, Republican water users exhibit a negative association between climate change belief and willingness to adopt potable water reuse. Interestingly, despite this, Republicans generally show a higher overall willingness to adopt potable water reuse compared to non-Republicans. These findings suggest that contextual factors in Albuquerque, New Mexico, in which challenges of aridity and economic dependence on water resources are pronounced, might be important aspects contributing to the Republican’s high willingness to adopt potable water reuse. Also, the current climate change communication strategy with the Republicans might not be appropriate, and it should be tailored to align with the Republicans’ beliefs and persuade them better.

Of this article's seven experiments, the first five demonstrate that virtually no Americans know the basic global warming mechanism. Fortunately, Experiments 2–5 found that 2–45 min of physical–chemical climate instruction durably increased such understandings. This mechanistic learning, or merely receiving seven highly germane statistical facts, also increased climate-change acceptance—across the liberal-conservative spectrum. However, Experiment 7's misleading statistics decreased such acceptance. These readily available attitudinal and conceptual changes through scientific information disconfirm what we term “stasis theory”—which some researchers and (...) many laypeople varyingly maintain. Stasis theory subsumes the claim that informing people about climate science may be largely futile or even counterproductive—a view that appears historically naïve, suffers from range restrictions, and/or misinterprets some polarization and correlational data. Our studies evidenced no polarizations. Finally, we introduce HowGlobalWarmingWorks.org—a website designed to directly enhance public “climate-change cognition.”. (shrink)

Discounting future costs and benefits is often defended on the ground that our descendants will be richer. Simply to treat the future as better off, however, is to commit an ecological fallacy. Even if our descendants are better off when we average across climate change scenarios, this cannot justify discounting costs and benefits in possible states of the world in which they are not. Giving due weight to catastrophe scenarios requires energetic action against climate change.

Can unilateral action be an effective response to global climate change? Baylor Johnson worries that a focus on unilateral action by individuals will detract from efforts to secure collective agreements to address the problem. Although Johnson and I agree that individuals have some obligation to reduce their personal emissions, we differ in the degree to which we see personal reductions as effective in spurring broader change. I argue that 'unilateral reductions' can have communicative value and that they can change (...) the structure of collective action problems, making such problems easier to solve. Since collective action problems are much less tractable where individuals abide by the tenets of traditional game theory and much more tractable where individuals are oriented to cooperate and to trust that others will reciprocate, we need moral norms that promote individual restraint in exploitation of the commons, and we ought ourselves to abide by those norms.

Climate change policy decisions are inescapably intertwined with future generations. Even if all carbon dioxide emissions were to be stopped today, most aspects of climate change would persist for hundreds of years, thus inevitably raising questions of intergenerational justice and sustainability. -/- The chapter begins with a short overview of discount rate debate in climate economics, followed by the observation that discounting implicitly makes the assumption that natural capital is always substitutable with man-made capital. The chapter explains (...) why non-substitutability matters if we are to take intergenerational justice seriously and invest aptly in mitigation. Non-substitutability simply implies that there are some forms of capital that cannot be substituted by another, and so consumption of one cannot be compensated with additional stocks of the other. The non-substitutability of critical natural capital can be defended without empirical data about preferences or the need to view the environment as a superior good, and the argument is presented through the language of keeping options open. -/- Those alive today make decisions about what natural capital to use and what to save for future. These choices are often represented as different points in a continuum of sustainability: weak sustainability is associated with a high degree of substitutability and therefore a lot of flexibility over what capital to consume, whereas strong sustainability is more stringent on substitutability. While it may be that in economical understanding weak and strong sustainability collapse into one another, philosophically the emphasis is slightly different. The chapter discusses how normative sustainability can be supported without ignoring opportunity costs and trade-offs. (shrink)

In this paper I argue that reflection on the threat of climate change brings out a distinct challenge for appeals to what I call the Anti-Demandingness Intuition, according to which a view about our obligations can be rejected if it would, as a general matter, require very large sacrifices of us. The ADI is often appealed to in order to reject the view that well off people are obligated to make substantial sacrifices in order to aid the global poor, (...) but the appeal to the same intuition is much less intuitively plausible against the view that we are obligated to make great sacrifices if that is the only way to avoid severe climate change. I claim that there are no plausible grounds on which to accept the ADI with respect to addressing global poverty while rejecting it with respect to avoiding severe climate change. I conclude that we should accept that morality is far more demanding than we typically accept, and suggest two lessons of my discussion regarding the practice of appealing to intuitions in moral argument.

Discussions of where the costs of climate change adaptation and mitigation should fall often focus on the 'polluter pays principle' or the 'ability to pay principle'. Simon Caney has recently defended a 'hybrid view', which includes versions of both of these principles. This article argues that Caney's view succeeds in overcoming several shortfalls of both principles, but is nevertheless subject to three important objections: first, it does not distinguish between those emissions which are hard to avoid and those which (...) are easy to avoid; second, its only partial reference to all-things-considered justice means it cannot provide a full account even of climate justice; and third, it assigns to the poor very limited duties to meet climate change costs, even where they have created those costs, which may incentivise them to increase emissions. An alternative pluralistic account which avoids these objections is presented. (shrink)

Anthropogenic climate change poses some difficult ethical quandaries for non-anthropocentrists. While it is hard to deny that climate change is a substantial moral ill, many types of non-human organisms stand to benefit from climate change. Modelling studies provide evidence that net primary productivity (NPP) could be substantially boosted, both regionally and globally, as a result of warming from increased concentrations of greenhouse gases. The same holds for deployment of certain types of climate engineering, or large-scale, technological (...) modifications of the global environment in order to prevent or slow anthropogenic climate change. For example, solar radiation management with stratospheric aerosol injections could benefit plant life by promoting enhanced photosynthesis, increasing diffuse radiation, and reducing heat stress. This has a surprising implication: from some non-anthropocentric perspectives, certain scenarios of climate change and climate engineering might bring about morally better states of affairs when compared to emission-mitigation baselines.

The human faculty of moral judgment is not well suited to address problems, like climate change, that are global in scope and remote in time. Advocates of ‘moral bioenhancement’ have proposed that we should investigate the use of medical technologies to make human beings more trusting and altruistic, and hence more willing to cooperate in efforts to mitigate the impacts of climate change. We survey recent accounts of the proximate and ultimate causes of human cooperation in order to (...) assess the prospects for bioenhancement. We identify a number of issues that are likely to be significant obstacles to effective bioenhancement, as well as areas for future research. (shrink)

Confucius is conventionally regarded as the founder of secular humanism and as a philosopher concerned about humans and culture. I would add to this that Confucius should also be read as an environmental philosopher. One reason is the pedagogical dimension in Confucianism, which points to Confucius as an environmental educator ? not the least of which since much of environmental education relies on common sense and an enlightened collective self-interest. Another reason is an aspect I call ?ecological intelligence?, which is (...) a key feature of ancient Confucianism and a signpost for the civil evolution that the mitigation of climate change demands from global civilization today.

A new generation of climate fiction called Cli-fi has emerged in the last decade, marking the strong consensus that has emerged over climate change. Science fiction’s concept of cognitive estrangement that combines a rational imperative to understand while focusing on something different from our everyday world provides one linkage between climate fiction and science fiction. Five novels representing this genre that has substantial connections with science fiction are analyzed, focusing on themes common across these books: their framing (...) of the climate change problem, their representations of science and scientists, their portrayals of economic and environmental challenges, and their scenarios for addressing the climate challenge. The analysis is framed through Taylor’s ideas of the social imaginary and the sociology of expectations, which proposes that expectations are promissory, deterministic, and performative. The novels illustrate in varying ways the problems attending the science-society relationship, the economic imperatives that have driven the characters’ choices, and the contradictory impulses that define our connections with nature. Such representations provide a picture of the challenges that need to be understood, but scenarios that offer possibilities for change are not as fully developed. This suggests that these books may represent a given moment in the longer trajectory of climate fiction while offering the initial building blocks to reconsider our ways of living so that new expectations and imaginaries can be debated and reconceived.

Issues about heritage, knowledge, and memory are central to climate change narratives. In an age when reality television stars become world leaders, the urgency of climate change narratives requires us to understand the crucial roles of memory and heritage to the future of our planet. The sanctity of knowledge simply cannot be abandoned. Knowledge slips away through the cracks, both in mainstream media efforts to sell its news and in the nonchalance of the admittedly more mindful scholars and (...) popularizers of climate change narratives. We face complex issues here, and there is an urgent need to reassess the value systems and ethics that brought us to where we are in terms of climate change. This is no easy task. To face this complex and controversial issue will require tremendous care with facts, honesty about heritage, and commitment to remembering. It will also need recognition of the painful fact that heritage can no longer be an excuse for continued derogation of the natural environment. (shrink)

Despite the awareness that climate change is an increasingly urgent issue to manage, little is being done to adequately achieve mitigation targets and ambitions. It has been suggested that this is due to ill-equipped normative frameworks and that common concepts, such as responsibility, harm, and justice, collapse when applied to climate change. One perspective has however been missing from this debate – the deep ecological perspective. The paper will investigate the deep ecological view and will argue that it (...) can provide a valuable contribution to normative issues pertaining to climate change. (shrink)
