Unlike resounding strikes and political agendas with much fanfare concerning the fight against the upcoming—or current, if you like it better—climate breakdown, little has been done to save the Earth and its atmosphere.

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 essay discusses the causes, significance, and skeptical arguments of climate change denialism, (...) as well as the roles of scientists and science communication in addressing the issues. Through this essay, we call for the active participation of scientists in science communication activities with the public, the opening of new science communication sectors specified for climate change, and more attention to social sciences and humanities in addressing climate change issues.

Environmental activism is crucial in increasing awareness of environmental degradation and preventing actions that harm the environment. A radical environmentalist movement has emerged within the community of activists. They advocate using illegal measures to attain their goals. This paper discusses these radical environmentalist groups’ motivations, their actions and their consequences. Activities that many consider unacceptable, such as art vandalism and road blockades, may result in adverse outcomes and diminish public support for environmental endeavors. We propose an alternative solidarity approach whereby (...) activists focus their efforts on disseminating information to the general public on climate change and other environmental issues, advocating for the adoption of eco-surplus culture, and fostering cooperation among governments, businesses, and individuals to develop effective solutions.

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.

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.

Many suggest that we should look backward and measure the differences among various parties' past emissions of greenhouse gases to allocate moral responsibility to remedy climate change. Such backward-looking approaches face two key objections: that previous emitters were unaware of the consequences of their actions, and that the emitters who should be held responsible have disappeared. I assess several arguments that try to counter these objections: the argument from strict liability, arguments that the beneficiary of harmful or unjust emissions (...) should pay, and arguments from distributive justice. I argue that none of these successfully justify a backward-looking approach to the temporally remote portion of the climate burden. (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.

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.

In discussions about responsibility for climate change, it is often suggested that the historical use of natural resources is in some way relevant to our current attempts to address this problem fairly. In particular, both theorists and actors in the public realm have argued that historical high-emitters of greenhouse gases (GHGs) – or the beneficiaries of those emissions – are in possession of some form of debt, deriving from their overuse of a natural resource that should have been shared (...) more equitably. These accounts of what might be termed ‘natural debt’ generally focus on one particular natural resource (global GHG sink capacity); invoke a principle of justice by which rights to consume this resource should have been allocated (most commonly, equal per capita shares); and then argue that historical violations of this principle give rise to certain rectificatory duties in the present (generally, duties on the part of those who have historically consumed an excessive amount of the world’s GHG sink capacity, or who have benefitted from such excess consumption, to offer some form of compensation to those who have not – such compensation usually taking the form of emission credits or cash). Though many seem to find it intuitively plausible that historical high-emissions have incurred some form of debt, significant challenges arise in rendering the concept of natural debt both coherent and defensible. Such problems are not, however, my focus in this piece. Instead, I here suggest that discussions about historical responsibility for climate change commonly fail to recognise certain other past injustices concerning natural resources that appear to hold contemporary relevance. In particular, I argue that it is not just the unequal consumption of global GHG sink capacity that may be of moral significance here; but also the way in which the world’s resources have more generally been governed.

This paper sets out a research agenda for a political theory of climate displacement, by critically examining one prominent proposal—the idea of a normative status for ‘climate refugees’—and by proposing an alternative. Drawing on empirical work on climate displacement, I show that the concept of the climate refugee obscures the complexity and heterogeneity of climate displacement. I argue that, because of this complexity and heterogeneity, approaches to climate displacement that put the concept of the (...) climate refugee at their centre will fail to treat like cases alike and relevantly different cases differently. In response to these failings, I outline an alternative—the pluralist theory of climate displacement—which confronts the specific challenges that climate displacement poses in different practical and institutional contexts, whilst also treating climate displacement as a unified phenomenon at the second-order level of burden-sharing.

We argue that concerns about double-counting—using the same evidence both to calibrate or tune climate models and also to confirm or verify that the models are adequate—deserve more careful scrutiny in climate modelling circles. It is widely held that double-counting is bad and that separate data must be used for calibration and confirmation. We show that this is far from obviously true, and that climate scientists may be confusing their targets. Our analysis turns on a Bayesian/relative-likelihood approach (...) to incremental confirmation. According to this approach, double-counting is entirely proper. We go on to discuss plausible difficulties with calibrating climate models, and we distinguish more and less ambitious notions of confirmation. Strong claims of confirmation may not, in many cases, be warranted, but it would be a mistake to regard double-counting as the culprit. 1 Introduction2 Remarks about Models and Adequacy-for-Purpose3 Evidence for Calibration Can Also Yield Comparative Confirmation3.1 Double-counting I3.2 Double-counting II4 Climate Science Examples: Comparative Confirmation in Practice4.1 Confirmation due to better and worse best fits4.2 Confirmation due to more and less plausible forcings values5 Old Evidence6 Doubts about the Relevance of Past Data7 Non-comparative Confirmation and Catch-Alls8 Climate Science Example: Non-comparative Confirmation and Catch-Alls in Practice9 Concluding Remarks.

Accusations of hypocrisy are a recurring theme in the public debate on climate change, but their significance remains poorly understood. Different motivations are associated with this accusation, which is leveled by proponents and opponents of climate action. In this article, I undertake a systematic assessment of climate hypocrisy, with a focus on lifestyle and political hypocrisy. I contextualize the corresponding accusation, introduce criteria for the conceptual analysis of climate hypocrisy, and develop an evaluative framework that allows (...) us to determine its moral significance. I argue that different instances of climate hypocrisy are problematic to different degrees, depending on how detrimental they are to an agent's attainment of environmental integrity. The resulting framework helps clear the confusion caused by disinformation campaigners, by distinguishing objectionable uses of the climate hypocrisy charge from constructive ones motivated by genuine concern for integrity.

A recent study showed that 78% of global climate science funding flows to European and North American institutions. Dr. Quan-Hoang Vuong gives his perspective on why this is a problem for the planet.

While the foundations of climate science and ethics are well established, fine-grained climate predictions, as well as policy-decisions, are beset with uncertainties. This chapter maps climate uncertainties and classifies them as to their ground, extent and location. A typology of uncertainty is presented, centered along the axes of scientific and moral uncertainty. This typology is illustrated with paradigmatic examples of uncertainty in climate science, climate ethics and climate economics. Subsequently, the chapter discusses the IPCC’s (...) preferred way of representing uncertainties and evaluates its strengths and weaknesses from a risk management perspective. Three general strategies for decision-makers to cope with climate uncertainty are outlined, the usefulness of which largely depends on whether or not decision-makers find themselves in a context of deep uncertainty. The chapter concludes by offering two recommendations to ease the work of policymakers, faced with the various uncertainties engrained in climate discourse. (shrink)

The importance of addressing the existential threat to humanity, climate change, has grown remarkedly in recent years while conflicting views and interests in societies exist. Therefore, climate change agendas have been weaponized to varying degrees, ranging from the international level between countries to the domestic level among political parties. In such contexts, climate change agendas are predominantly driven by political or economic ambitions, sometimes unconnected to concerns for environmental sustainability. Consequently, it can result in an environment that (...) fosters antagonism and disputes over power and position and increases the risk of prolonged confrontations, hindering the collective global efforts to mitigate and adapt to climate change. Through the current discourse, we aim to provide a preliminary definition of the weaponization of climate change and environmental degradation and examine its risks and consequences on international relations, political dynamics, public perception, and the comprehensive integrity of climate action. We also recommend embracing a globally coordinated, scientifically substantiated approach to circumvent climate change by building an eco-surplus cultural value system. (shrink)

Climate change adaptation is largely a local matter, and adaptation planning can benefit from local climate change projections. Such projections are typically generated by accepting climate model outputs in a relatively uncritical way. We argue, based on the IPCC’s treatment of model outputs from the CMIP5 ensemble, that this approach is unwarranted and that subjective expert judgment should play a central role in the provision of local climate change projections intended to support decision-making.

Climate change threatens to infringe the human rights of many. Taking an optimistic stance, climate engineering might reduce the extent to which such rights are infringed, but it might also bring about other rights infringements. This Forum, leading off the special issue on climate engineering governance, engages three scholars in a discussion of three core issues at the intersection of human rights and climate engineering. The Forum is divided into three sections, each authored by a different (...) scholar and discussing a distinct aspect of this relationship. First, Toby Svoboda gives an overarching view of three competing approaches to human rights, grounded in philosophy; then, Holly Jean Buck looks at lessons from how the climate migration conversation brings a human rights approach to a climate policy issue; and finally, Pablo Suarez illustrates how a humanitarian approach to climate engineering works with a human rights framework. The conclusion of the Forum draws together points of overlap across the three sections and suggests a path forward for policy and research on this topic. Together, the sections show that climate engineering, should it materialize, will pose novel human rights challenges, and may well force reconsideration of how human rights are applied as a guide to action.

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)

The effects of anthropogenic climate change may be devastating. Nevertheless, most people do not seem to be seriously concerned. We consume as much as we always did, drive as much as we always did, eat as much meat as we always did. What can we do to overcome this collective apathy? In order to be able to develop effective measures, we must first get clear about the causes of climate change inaction. In this paper I ask whether moral (...) nihilism is a significant cause of climate change inaction. The answer to this question depends mainly on the extent to which being a moral nihilist reduces one's likelihood of taking action against climate change. At first sight, the extent seems to be considerable. I argue, however, that this assumption is false. Only slightly more non-nihilists than nihilists are led to climate-friendly actions by moral considerations. And in absolute terms, morality plays such a minor role in leading people to act that the difference is barely noticeable. (shrink)

Philosophy of science has witnessed substantial recent debate over the existence of a structural analogue of chaos, which is alleged to spell trouble for certain uses of climate models. The debate over the analogy can and should be separated from its alleged epistemic implications: chaos-like behavior is neither necessary nor sufficient for small dynamical misrepresentations to generate erroneous results. The kind of sensitivity that matters in epistemology is one that induces unsafe beliefs, and the existence of a structural analogue (...) to chaos is better seen as an explanation for known safety failures than as providing evidence for unknown ones.

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 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 concepts are crucial to understand the effects of human activity on the climate system scientifically, and to formulate and pursue policies to mitigate and adapt to these effects. Yet, scientists, policymakers, and activists often use different terms such as “global warming,” “climate change,” “climate crisis,” or “climate emergency.” This advanced review investigates which climate concept is most suitable when we pursue mitigation and adaptation goals in a scientifically informed manner. It first discusses how (...) survey experiments and social science reviews on climate frames draw normative recommendations about which terms to use for public climate communication. It is suggested that such normative claims can be refined by including the scientific alongside lay uses of a climate concept, and by using explicit assessment conditions to evaluate how suitable a concept is for formulating mitigation and adaptation goals. Drawing on philosophical theories of conceptual change in science and conceptual engineering, a novel framework with two assessment conditions is introduced and then applied to “global warming,” “climate change,” “climate emergency,” and “climate crisis.” The assessment suggests that currently, “climate crisis” is most suitable to formulate and pursue climate mitigation and adaptation goals. Using this concept promotes the epistemic goals of climate science to a high degree, bridges scientific, political, and activist discourse, and fosters for democratic participation when articulating climate policies.

There is a common belief that genuine awareness and acceptance of the existence of anthropogenic climate change (as opposed to either ignorance or denial) automatically leads one to develop political and moral positions which advocate for collective human action toward minimizing suffering for all and adapting human societies toward a fossil-free future. This is a mistake. Against the idea that scientific awareness of the facts of climate change is enough to motivate a common ethical project of humanity toward (...) a unifying good, I argue that climate change awareness can just as well equally motivate heightened divisions of humanity into anti-egalitarian, xenophobic, class-differentiated zones of competitive survival. I call this climate barbarism, and seek to explain its conceptual grounds. (shrink)

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)

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)

Climate change appears to be a classic aggregation problem, in which billions of individuals perform actions none of which seem to be morally wrong taken in isolation, and yet which combine to drive the global concentration of greenhouse gases (GHGs) ever higher toward environmental (and humanitarian) catastrophe. When an individual can choose between actions that will emit differing amounts of GHGs―such as to choose a vegan rather than carnivorous meal, to ride a bike to work rather than drive a (...) car, or to take a reusable bag to the supermarket rather than send another plastic bag to landfill―does she have any reason to choose the lower-emitting actions? In this chapter I'll reject the claim that individuals don't make a difference when it comes to climate change. I first discuss making a difference with every action, as a way of getting clearer about how individuals' actions impact causally on the harms resulting from climate change, making a distinction so far overlooked in the climate ethics discussion between 'macro' thresholds like ice-cap melt, and 'micro' thresholds like severe weather events. I set aside making a difference with every action as implausible, and then move on to discuss both low probability of major difference, and high probability of minor difference. I argue that both of these are plausible characterizations of individuals' causal contributions to climate change. I conclude by noting some policy implications of having (probabilistic) individual difference-making back in play. (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.

Much of the climate justice discussion revolves around how the remaining carbon budget should be globally allocated. Some authors defend the unjust enrichment interpretation of the beneficiary pays principle (BPP). According to this principle, those states unjustly enriched from historical emissions should pay. I argue that if the BPP is to be constructed along the lines of the unjust enrichment doctrine, countervailing reasons that might be able to block the existence of a duty of restitution should be assessed. One (...) might think that the duty to provide restitution no longer has moral weight if many benefits were already consumed, if the particular benefits obtained from historical emissions cannot be transferred from one country to another, or if present members of developed countries framed their life plans based upon the expectation of continued possession of those benefits. I show that none of these reasons negate the duty to provide restitution. (shrink)

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)

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)

Climate change continues to have recognizable impacts across the globe, as weather patterns shift and impacts accumulate and intensify. In this wider context, urban areas face significant challenges as they attempt to mitigate dynamic changes at the local level — changes such as those caused by intensifying weather events, the disruption of critical supplies, and the deterioration of local ecosystems. One field that could help urban areas address these challenges is conservation biology. However, this paper presents the argument that (...) work in urban contexts may be especially difficult for conservation biologists. In light of current climate change predictions, conservation biology may need to abandon some of its core values in favor of commitments guiding urban ecology. More broadly, this essay aims to reconcile the goals of restoration and conservation, by reconceptualizing what an ecosystem is, in the context of a world threatened by global climate change.

Climate change, pollution, and deforestation have a negative impact on global mental health. There is an environmental justice dimension to this challenge as wealthy people and high-income countries are major contributors to climate change and pollution, while poor people and low-income countries are heavily affected by the consequences. Using state-of-the art data mining, we analyzed and visualized the global research landscape on mental health, climate change, pollution and deforestation over a 15-year period. Metadata of papers were exported (...) from PubMed®, and both relevance and relatedness of terms in different time frames were computed using VOSviewer. Co-occurrence graphs were used to visualize results. The development of exemplary terms over time was plotted separately. The number of research papers on mental health and environmental challenges is growing in a linear fashion. Major topics are climate change, chemical pollution, including psychiatric medication in wastewater, and neurobiological effects. Research on specific psychiatric syndromes and diseases, particularly on their ethical and social aspects is less prominent. There is a growing body of research literature on links between mental health, climate change, pollution, and deforestation. This research provides a graphic overview to mental healthcare professionals and political stakeholders. Social and ethical aspects of the climate change-mental health link have been neglected, and more research is needed. (shrink)

The Polluter Pays, Then Receives (PPTR) principle claims that, had an agent innocently benefited from climate change, it owes moral obligations to the polluters who contributed to a warmer globe. This critical review assesses the evidence, the externalities argument, and the luck egalitarian approach and suggests that there are profound flaws in each of them. In consequence, the PPTR fails to accomplish its objective to incentivise efficient practices since polluting should neither be incentivised nor considered an efficient practice.

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)

This Correspondence argues in response to Coolsaet et al. (2024) that there is an important role to play for stance-independent justice discussions that are not tied to specific social, political or critical perspectives. These can be valuable for climate research audiences, but also as a basis upon which to critically debate and research injustices.

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 urgent need to address climate change poses a range of complex moral and practical concerns, not least because rising to the challenge will require cooperation among countries that differ greatly in their wealth, the extent of their contributions to the problem, and their vulnerability to environmental and economic shocks. This thesis by publication in the field of climate ethics aims to characterise a range of national responsibilities associated with acting on climate change (Part I), and to (...) identify proposals for fulfilling those responsibilities through fair and feasible institutional arrangements (Part II). I aim not only to address substantive gaps in scholarly understanding of those responsibilities, but also to strengthen the ability of climate ethics to engage meaningfully with climate policy. Chapter 2 addresses the question of whether wealthy countries owe a “climate debt” to poor countries. It finds that even if climate debt (suitably interpreted) may provide a coherent and morally plausible concept, its political value as a discursive frame that can provide a basis for cooperation is limited. Chapter 3 investigates the role that equity may play in negotiations on a long-term climate change agreement. It argues that developed and developing countries may reach a “principled bargain” if both converge on a way of differentiating their responsibilities that places less emphasis on a rigid dichotomy between the two groups and more emphasis on objective criteria relating to their contribution to the problem and capacity to address it. Chapter 4 explores a question largely overlooked in climate ethics, namely whether wealthy countries owe compensation to those who are adversely affected by the climate policies which they enact. I find that enacting countries have responsibilities to compensate both domestic and foreign citizens who would suffer disproportionate losses from the effects of policies. Chapter 5 assesses whether wealthy countries may legitimately adopt unilateral (or “fragmented”) rather than multilaterally coordinated approaches to raising climate finance for developing countries. It finds that coordinated target-setting, effort sharing and oversight arrangements are essential, but that a mix of unilateral and coordinated approaches to raising funds will be necessary for securing legitimacy. In Chapter 6, through addressing the broader question of what should count as official aid, I consider whether wealthy countries may draw on aid budgets to support developing countries’ efforts to address climate change. I find that the current definition of official aid should be retained but supplemented by specified exclusions from eligibility in order to preserve the aid regime’s integrity. Nevertheless, some climate finance may justifiably be counted as aid provided that concerns relating to the diversion of aid funding are addressed. In addressing these research questions, the thesis seeks not only to make original theoretical contributions to climate ethics but also to strengthen broader scholarly understanding of the ways in which ethics and international public policy may inform one another, particularly by highlighting the role of framing considerations (Chapter 2), feasibility considerations (Chapter 3), and the ways in which principles of fairness and legitimacy map onto institutional functions (Chapters 4, 5 and 6).

Climate change – and its most dangerous consequence, the rapid overheating of the planet – is not the offspring of a natural procedure; instead, it is human-induced. It is only the aftermath of a specific pattern of conomic development, one that focuses mainly on economic growth rather than on quality of life and sustainability. Since climate change is a major threat not only to millions of humans, but also to numerous non-human species and other forms of life, as (...) well as to the equilibrium and the viability of the very planet, addressing it is of dire importance. In this chapter it will be argued that addressing the threat of climate change is primarily a task and a challenge for ethics, since the stabilization and gradual amelioration of the situation requires abandoning an up to now dominant model of life, longestablished customs and a so far cogent system of moral values. It will be further maintained that this for ethics might – or, even, should – become a new categorical imperative, since preserving the viability of the planet is a fundamental moral duty not only towards the existing members of the moral community, but also towards future generations.

Climate change mitigation has become a paradigm case both for externalities in general and for the game-theoretic model of the Tragedy of the Commons (ToC) in particular. This situation is worrying, as we have reasons to suspect that some models in the social sciences are apt to be performative to the extent that they can become self-fulfilling prophecies. Framing climate change mitigation as a hardly solvable coordination problem may force us into a worse situation, by changing real-world behaviour (...) to fit our model, rather than the other way around. But while this problem of the performativity of the ToC has been noted in a recent paper in this journal by Matthew Kopec, his proposed strategies for dealing with their self-fulfilling nature fall short of providing an adequate solution. Instead of relying on the idea that modelling assumptions are always strictly speaking false, this paper shows that the problem may be better framed as a problem of underdetermination between competing explanations. Our goal here is to provide a framework for choosing between this set of competing models that allows us to avoid a ‘Russian Roulette’-like situation in which we gamble with existential risk.

A collection of original and innovative essays that compare the justice issues raised by climate engineering to the justice issues raised by competing approaches to solving the climate problem.

Over the past two decades, virtue ethicists have begun to devote increasing attention to applied ethics. In particular, the application of virtue ethical frameworks to the environmental ethics debate has flourished. This chapter reviews recent contributions to the literature in this field and highlights some strengths and weaknesses of thinking about climate change through a virtue ethical lens. Section “Two Benefits of Virtue Ethical Approaches to Climate Change” explores two benefits of applying virtue ethics to climate change: (...) (a) we can better capture the phenomenology of our moral experience, and (b) we avoid the problem of inconsequentialism. Section “A Catalogue of Environmental Virtues” analyzes various practical proposals that have been put forward in the form of specific environmental virtues. Section “An Objection to Virtue-Oriented Approaches to Climate Change” reconstructs a fundamental objection to the idea of using a virtue ethical normative approach to tackling the urgent and imminent dangers of climate change.

The emphasis on general distributive principles in the climate justice literature has left significant gaps regarding the problem of weak climate governance. The main contribution of this chapter is to show how normative theory can contribute to addressing the apparent political incapacity to respond to the threat of climate disruption. The chapter argues that a set of six underlying obstacles to effective climate change politics can serve as a framework around which ‘non-ideal’ normative theorizing about (...) class='Hi'>climate politics can be organized. Policies and other tactics to mediate the six obstacles are shown to raise distinct normative issues in need of deeper analysis. (shrink)

The sixth IPCC report states that a proper conception of climate justice that can address the complexity of the phenomenon of anthropogenic climate change as a whole requires considering not only one but rather three dimensions of justice today: redistributive, procedural, and recognition dimensions. In this article, my focus is on exploring the latter dimension, drawing special attention to climate policies addressing cultural-identity issues. In the first section, I illustrate how climate policies can be connected to (...) discriminatory practices against minority cultures and their identities. To do so, I take the struggles of Black movements against environmental racism and the struggles of Indigenous peoples against a colonialist cultural heritage as case studies. In the second section, I look into the most advanced normative model to address the dimension of recognition, its advantages, and how it addresses the so-called ‘institutionalization of cultural patterns’ in climate policies: the Nancy Fraser model. Finally, in the third section, I investigate an aspect that remains open. It concerns the matter of how to use institutional authority to ‘deinstitutionalize’ non-ecological cultural patterns, while respecting pluralism and avoiding falling into the risks of institutional paternalism.

Climate ethics has been concerned with polluter pays, beneficiary pays and ability to pay principles, all of which consider climate change as a single negative externality. This paper considers it as a constellation of externalities, positive and negative, with different associated demands of justice. This is important because explicitly considering positive externalities has not to our knowledge been done in the climate ethics literature. Specifically, it is argued that those who enjoy passive gains from climate change (...) owe gains not to the net losers, but to the emitters, just as the emitters owe compensation to the net losers for the negative externality. This is defended by appeal to theoretical virtues and to the social benefits of generating positive externalities, even when those positive externalities are coupled with far greater negative externalities. We call this the Polluter Pays, Then Receives ('PPTR', or 'Peter') Principle. This principle is then applied at two levels in the context of Canada. [Open access]. (shrink)

Accelerating global climate change drives new climate risks. People around the world are researching, designing, and implementing strategies to manage these risks. Identifying and implementing sound climate risk management strategies poses nontrivial challenges including (a) linking the required disciplines, (b) identifying relevant values and objectives, (c) identifying and quantifying important uncertainties, (d) resolving interactions between decision levers and the system dynamics, (e) quantifying the trade-offs between diverse values under deep and dynamic uncertainties, (f) communicating to inform decisions, (...) and (g) learning from the decision-making needs to inform research design. Here we review these challenges and avenues to overcome them. ▪ People and institutions are confronted with emerging and dynamic climate risks. ▪ Stakeholder values are central to defining the decision problem. ▪ Mission-oriented basic research helps to improve the design of climate risk management strategies.

The intuition of neutrality, as discussed by John Broome, says that the addition of people does not, by itself, produce or subtract value from the world. Such intuition allows us to disregard the effects of climate change policy onto the size of populations, effectively allowing us to make policy recommendations. Broome has argued that the intuition has to go. Orsi responds by urging a normative (rather than Broome's axiological) interpretation of neutrality in terms of an exclusionary permission to disregard (...) the value of adding lives. He explores justifications and limits of such permission by referring to the prospect of human extinction. (shrink)

Dale Jamieson has claimed that conventional human-directed ethical concepts are an inadequate means for accurately understanding our duty to respond to climate change. Furthermore, he suggests that a responsibility to respect nature can instead provide the appropriate framework with which to understand such a duty. Stephen Gardiner has responded by claiming that climate change is a clear case of ethical responsibility, but the failure of institutions to respond to it creates a (not unprecedented) political problem. In assessing the (...) debate between Gardiner and Jamieson, I develop an analysis which shows a three-part structure to the problem of climate change, in which the problem Gardiner identifies is only one of three sub-problems of climate change. This analysis highlights difficulties with Jamieson’s argument that the duty of respect for nature is necessary for a full understanding of climate ethics, and suggests how a human-directed approach based on the three-part analysis can avoid Jamieson’s charge of inadequacy.

Some philosophers are skeptical that individuals are morally blameworthy for their own greenhouse gas emissions. Although an individual’s emissions may contribute to climate change that is on the whole very harmful, perhaps that contribution is too trivial to render it morally impermissible. Against this view, there have been attempts to show that an individual’s lifetime emissions cause non-trivial harm, but in this paper I will consider what follows if it is true that an individual is not blameworthy for her (...) emissions. Specifically, I ask how a non-blameworthy emitter would best regard his or her own emissions. I will argue that the appropriate attitude to adopt here is one of agent-regret. This allows us to capture the moral disvalue of one’s emissions without entailing blame for them. *Links to the paper and video overview below.*. (shrink)

We make the case that scientifically accurate and politically feasible responses to the climate crisis require a complex understanding of human cultural practices of niche construction that moves beyond the adaptive significance of culture. We develop this thesis in two related ways. First, we argue that cumulative cultural practices of niche construction can generate stable equilibria and runaway selection processes that result in long-term existential risks within and across cultural groups. We dub this the back of the invisible hand. (...) Second, we argue that the ability of cultural groups to innovate technological solutions to environmental problems is highly constrained in ways that are exacerbated by sustained intergroup conflict, inequality and by inherently unpredictable cascades in climate change and human migration patterns. After developing these theoretical points about human cultural practices of niche construction in detail, we conclude our discussion with some tentative practical suggestions about the way that cultural evolutionary history can more fruitfully be used in efforts to remit the climate crisis and contribute to sustainable practices of human climate change adaptation.
