In this article, we analyse the role that artificial intelligence (AI) could play, and is playing, to combat global climate change. We identify two crucial opportunities that AI offers in this domain: it can help improve and expand current understanding of climate change, and it can contribute to combatting the climate crisis effectively. However, the development of AI also raises two sets of problems when considering climate change: the possible exacerbation of social and (...) ethical challenges already associated with AI, and the contribution to climate change of the greenhouse gases emitted by training data and computation-intensive AI systems. We assess the carbon footprint of AI research, and the factors that influence AI’s greenhouse gas (GHG) emissions in this domain. We find that the carbon footprint of AI research may be significant and highlight the need for more evidence concerning the trade-off between the GHG emissions generated by AI research and the energy and resource efficiency gains that AI can offer. In light of our analysis, we argue that leveraging the opportunities offered by AI for global climate change whilst limiting its risks is a gambit which requires responsive, evidence-based, and effective governance to become a winning strategy. We conclude by identifying the European Union as being especially well-placed to play a leading role in this policy response and provide 13 recommendations that are designed to identify and harness the opportunities of AI for combatting climate change, while reducing its impact on the environment.

Does it make sense to talk about corporate responsibility for climate change mitigation? Through utilizing systems thinking, I will argue that mitigation should be incorporated into corpora...

Despite growing interest in risks of societal collapse due to anthropogenic climate change, there exists no consensus about how collapse should be understood. In this article, we critically examine existing definitions and argue that none adequately address the challenges for conceptualizing collapse that climate change presents. We therefore propose an alternative conception, which regards collapse as a reduction of collective capacity resulting in a pervasive and difficult-to-reverse loss of basic functionality. Our conception is dynamic in that (...) it focuses on the interrelations of constituent subsystems. It also distinguishes collapse from transformations needed to address climate change and provides insight into the relationship between collapse and sustainability. [Open access]. (shrink)

The aim of this article is not to make any arguments that oppose veganism or having children or, in any way, to denigrate those who make them. Rather, the intention is twofold: To attack the inconsistency of those who make arguments for veganism in relation to climate change and the natural world, but who omit to make arguments against having children and the problem of rapidly increasing global population on the same grounds. To attack a form of sanctimony (...) which manifests itself in inconsistent applications of such arguments and which exploits genuine and very serious problems in ways that aim to bring power to their advocates by inducing a sense of shame in their victims. In this way, such moralists try to strengthen the legitimacy of their own preferences – preferences that often run into conflict with other concerns based on the same arguments. (shrink)

Travis Rieder's Toward a Small Family Ethic confronts the effects of population growth and addresses what individual procreative obligations might follow from it. In this review, I summarize the main arguments that Rieder deploys to defend his position that those with large ecological footprints morally ought to follow a small family ethic. I express sympathy with some of his claims and praise the book's accessibility, but its short length inevitably means that some important issues are omitted or given only superficial (...) treatment. I highlight a few of those issues at the end of the review. (shrink)

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)

Multiple states are at risk of becoming uninhabitable due to climate change, forcing their populations to flee. While the 1951 Refugee Convention provides the gold standard of international protection, it is only applied to a limited subset of people fleeing their countries, those who suffer persecution, which most people fleeing climate change cannot establish. While many journalists and non-lawyers freely use the term “climate refugees,” governments, and courts, as well as UNHCR and many refugee experts, (...) have excluded most climate refugees from the Convention as a matter of legal interpretation. In our 2015 paper, “Unable to Return in the 1951 Refugee Convention: Stateless Refugees and Climate Change”, we sought to reopen the debate on “climate refugees” by arguing that some climate refugees qualify under the 1951 Convention as it is currently written (even if they are not persecuted): those who are stateless and are unable to return to their country of origin because climate change has rendered it uninhabitable. Our interpretation, however, has been rejected by Goodwin-Gill and McAdam (2021) and by Foster and Lambert (2019), which explicitly responds to our paper. Here, we address and respond to their arguments, and develop a new supplementary one, drawing on the principle of systemic integration, as enshrined in Article 31(3)(c) of the Vienna Convention on the Law of Treaties.

We hypothesize that under the predicted scenario of climate change epigenetically mediated environmental sex determination could become an epigenetic trap. Epigenetically regulated environmental sex determination is a mechanism by which species can modulate their breeding strategies to accommodate environmental change. Growing evidence suggests that epigenetic mechanisms may play a key role in phenotypic plasticity and in the rapid adaptation of species to environmental change, through the capacity of organisms to maintain a non‐genetic plastic memory of the (...) environmental and ecological conditions experienced by their parents. However, inherited epigenetic variation could also be maladaptive, becoming an epigenetic trap. This is because environmental sex determination can alter sex ratios by increasing the survival of one of the sexes at the expense of negative fitness consequences for the other, which could lead not only to the collapse of natural populations, but also have an impact in farmed animal and plant species.

In this chapter I zoom in on a topic in climate ethics that has not previously received academic scrutiny: the intersection between evolutionary ethics and climate change. I argue that in the context of climate discourse, an evolutionary perspective can be illuminating, but may also invite moral corruption and reasoning fallacies. Relating my discussion to the general theme of the book, I argue that academic philosophy is well-positioned to fulfil a specific societal role, which is particularly (...) important in the age of popular science: to raise awareness of the ethical predicaments to which scientific findings can give rise, and to highlight the normative assumptions implicit in the reasoning of science communicators.

Henry Shue’s latest book, The Pivotal Generation: Why We Have a Moral Responsibility to Slow Climate Change Right Now, is an excellent read, both clear and comprehensive. It is written in a way that makes it accessible to philosophers and non-philosophers alike. The book argues persuasively that the people alive today must take immediate and drastic action to tackle climate change, as the current decade will be crucial for determining how severe the impacts will become. Shue (...) warns how a sharp division into past, present, and future is misleading when it comes to climate change and can obfuscate the extent of the responsibility that the current generations bear. For us to acknowledge our responsibility, we must recognise how deeply intertwined our lives are with both the past and the future. One of these innate deep connections between generations is the extensive time period that carbon emissions can continue to contribute to climate change, for dozens of centuries. -/- The current generations have been bequeathed an energy system that relies on fossil fuels and that continues to add greenhouse gases to the atmosphere. For over two centuries now, the planet has been getting warmer as an unintended side effect of industrialisation. We are the first humans to understand the dynamics of the Earth’s climate and how human actions cause anthropogenic climate change. With the rapidly advanced scientific knowledge, it has become apparent that there is a need to quickly transition to a different energy regime. Shue points out that this knowledge has made us the first humans to recognise that action is required, but the urgency of the problem also makes us possibly the last to still be able to act before certain major threats are aggravated. With many irreversible climate change impacts, the date-of-last-opportunity to take action to prevent them might be very soon. According to Shue (2021, p. 6), “This gives us an awesome responsibility. Humans have accidentally set our own house on fire, and if we do not douse the flames while they are no more extensive than they are now, it may not be possible ever to extinguish them”. That is why we alive now are the pivotal generation. -/- Although a sense of urgency runs through the book and the seriousness of the situation is made very clear, Shue steers away from fearmongering. He does not think that human extinction is around the corner, but underlines that we cannot rule out such threats until we stop feeding the beast. Unless we cap emissions at a relatively safe level and transform our infrastructure to net zero, we will keep on increasing risks to future people by “adding continuously to the mushrooming danger” (p. 23). The book stresses that the possibility of passing several tipping points adds to the urgency and the risks because when positive feedback mechanisms are triggered, climate change accelerates. These positive feedbacks can feed into each other, such as when warming seawater melts even more ice, with the possibility of a cascade of feedbacks if enough tipping points are passed. Such changes are irreversible and could themselves become further positive feedbacks. Shue (pp. 24–25) warns that it is “likely that the near future is the last chance to avoid passing significant tipping points and entirely possible that the near future is the last chance to avoid provoking a cascade of tipping points” (emphasis in original). -/- While I applaud the general message of Shue’s book, I find that the brushstrokes he uses when identifying those responsible are a little too broad. The reason for this is twofold. Firstly, it is questionable as to how many of us really know enough about the risks we are leaving future generations with. Secondly, discussion in terms of generations underplays the big differences between the responsibility of different groups of actors within them. In what follows, I will elaborate on these points. I should note from the outset, however, that although I think that these are important issues, I find them to be points of clarification in an impressive and ambitious book on why our actions have such significance and why objections to urgent, large-scale climate action are misplaced.

Over the last few decades climate change has been gaining importance in international scientific and political debates. However, the social sciences, especially in Latin America, have only lately become interested in the subject and their approach is still vague. Scientific understanding of global environmental change and the process of designing public policies to face them are characterized by their complexity as well as by epistemic and normative uncertainties. This makes it necessary to problematize the way in which (...) research efforts understand ‘the social’ of climate change. How do ‘the climate’ and ‘the social’ interpenetrate as scientific objects? What does the resulting field look like? Is the combination capable of promoting reflexivity and collaboration on the issue, or does it merely become dispersed with diffuse boundaries? Our paper seeks to answer these and other related questions using Chile as a case study and examining peer-reviewed scientific research on the topic. By combining in-depth qualitative content analysis of each paper with a statistical meta-analysis, we were able to: characterize the key content and forms of such literature; identify divisions and patterns within it; and, discuss some factors and trends that may help explain these. We conclude that the literature displays two competing trends: while it is inclined to become fragmented beyond the scope of the ‘mitigation’ black box, it also tends to cluster along the lines of methodological distinctions traditionally contested within the social sciences. This, in turn, highlights the persistence of disciplinary divisions within an allegedly interdisciplinary field. (shrink)

The Covid-19 pandemic has confronted humanity with a complex and unexpected challenge. One part of this challenge concerned individual ethics, i.e., the behaviour of individuals with respect to the rules and restrictions that have been imposed by health authorities in the collective interest. Another part concerned, instead, the social organisation of immunisation campaigns. In this article I wonder whether the lessons we have learned in the fight against the Covid-19 pandemic can be applied to climate change mitigation. My (...) first argument is that at least some of the ethical successes obtained at the individual level can be repeated with respect to climate change, but only if we stop focusing solely on the risks of climate change and offer a convincing picture of the benefits and opportunities of a more sustainable world. The second argument is that the Covid-19 pandemic offered us a new perspective on the relationship between global systemic threats and social justice: no one can adapt in isolation, neither medically nor economically. An out-of-control climate will lead to the same situation, so the asymmetry of vulnerability between developed and developing countries is only a short-term illusion. (shrink)

The prominent burden-sharing principles in the emerging literature of the political theory of climate change fail to sufficiently tackle the task they set out to solve. This paper sets out properties that an alternative principle should aim to meet. Based on these properties, it develops a consequentialist moral principle – the wastefulness principle. This principle holds that it is wrong to waste a shared, scarce resource. The paper argues that this principle can be used to solve the question (...) of who should bear the burdens of anthropogenic climate change in a more suitable way than existing principles. After developing the wastefulness principle, this paper discusses in a non-exhaustive manner how it can be employed in the real world, which challenges it might meet, and how additional principles might solve them.

Adaptation to climate change impacts is a key research topic in business ethics that poses substantial implications on the good lives of human beings. The commercial port sector is a highly relevant study focus with its pivotal roles in supply chains and international trade. Hence, it is important to investigate whether the port planning system and practice is appropriate in tackling climate change impacts. But beforehand, we must thoroughly understand the attitude and behaviors of port planners (...) and operators on ports’ climate adaptation planning. Through a survey towards 21 ports in Canada, the paper investigates the attitude and behaviors of port planners and operators on ports’ climate adaptation planning. Towards the end, we propose a new approach so as to enable port stakeholders to carry out climate adaptation planning effectively. The paper offers important insight to researchers to investigate the ways in developing effective climate adaptation plans and practice for ports and other business sectors. (shrink)

The topic of my thesis is individual and collective responsibility for collectively caused systemic harms, with climate change as the case study. Can an individual be responsible for these harms, and if so, how? Furthermore, what does it mean to say that a collective is responsible? A related question, and the second main theme, is how ignorance and knowledge affect our responsibility. -/- My aim is to show that despite the various complexities involved, an individual can have responsibility (...) to address climate change. I argue that climate change is not a problem just for states and international bodies, but also for individuals. There are three possible sources of moral responsibility for individuals in relation to climate change harms: direct responsibility (individuals qua individuals), shared responsibility as members (individuals qua members of collective agents), and shared responsibility as constituents (individuals qua constituents of unorganised collectives). -/- Accounts that deny individual responsibility fail to either take our interdependent reality seriously or fail to understand marginal participation (or in the case direct responsibility, fail to appreciate the nature of the climate change phenomenon). Individuals can be complicit in climate change harms, either as members of collective agents (e.g. as citizens of states or employees of a corporation) or as constituents of unorganised collectives (e.g. as consumers or polluters). -/- Although I focus on individual complicity, I do not deny the obligations of collective agents. However, nation-states, governments, and international bodies are not the only relevant collective agents in climate ethics: other collective agents, such as corporations, matter also and can have obligations concerning making sure that their activities are as carbon-neutral as possible. In addition, those corporations that have engaged in lobbying against climate regulation through creating and disseminating misleading information have acquired themselves additional obligations to mitigate climate change and compensate for the harm they have caused. Even so, the ethical claims can only be understood by individual members of these collective agents because only they can feel the pull of moral claims. I suggest that we could distinguish between what one must possess in order to be capable of making moral claims (i.e. moral agency conditions), and what it means to have the ability to exhibit such claims through one’s conduct. -/- Individual direct responsibility is to not to increase the probable risk of serious harm to other people, at least as long as we can do so at a less than significant cost to ourselves. It is limited to relatively wealthy individuals. Offsetting is not a reliable way to meet this duty; we need to look at the emissions from our lifestyle choices (within the available infrastructure). Shared responsibility qua members of collective agents is the key individual responsibility, and it presses especially on those occupying key positions within key collective agents. Saying that, our shared responsibility qua constituents of unorganised collectives has the potential to be decisive in whether some action is taken or not, either through a set of actions that can signal certain acceptance or support, or as a form of political support from the grass roots.

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 (...) class='Hi'>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.

This paper argues that climate migration-in case of climate refugees in a strict sense-differs from other forms of migration not only by its finality but also by the fact that entire communities are forced to resettle elsewhere.

Ensuring that their equal participation rights are not merely formal but have ‘fair value’ requires taking cultural differences into account to ensure that they do not pose substantial disadvantages for participation in the political and social sphere.

Agnotology is the study of how ignorance arises via circulation of misinformation calculated to mislead. Legates et al. had questioned the applicability of agnotology to politically-charged debates. In their reply, Bedford and Cook, seeking to apply agnotology to climate science, asserted that fossil-fuel interests had promoted doubt about a climate consensus. Their definition of climate ‘misinformation’ was contingent upon the post-modernist assumptions that scientific truth is discernible by measuring a consensus among experts, and that a near unanimous (...) consensus exists. However, inspection of a claim by Cook et al. of 97.1 % consensus, heavily relied upon by Bedford and Cook, shows just 0.3 % endorsement of the standard definition of consensus: that most warming since 1950 is anthropogenic. Agnotology, then, is a two-edged sword since either side in a debate may claim that general ignorance arises from misinformation allegedly circulated by the other. Significant questions about anthropogenic influences on climate remain. Therefore, Legates et al. appropriately asserted that partisan presentations of controversies stifle debate and have no place in education. (shrink)

Vaikka suurin osa viimeaikaisesta ilmaston lämpenemisestä on ihmisten aiheuttamaa antropogeenista lämpenemistä, yksittäisten ihmisten kausaalinen vaikutus ilmastonmuutokseen on minimaalinen, jopa mitätön. Tämän takia jotkut väittävät, että on harhaanjohtavaa pitää yksilöitä vastuussa ilmastonmuutoksesta. Tällainen argumentointi perustuu perinteisiin vastuutulkintoihin ja -käsitteisiin, joissa vastuun perustana painotetaan toimijan näkökulmaa ja hänen kausaalista rooliaan: jos toimijan teot tai tekemättä jättämiset eivät vaikuta lopputulokseen, hän ei ole vastuussa siitä. Ilmastonmuutoksessa on toinenkin vastuukäsitysten kannalta ongelmallinen seikka, intentionaalisuus eli tahallisuus: ihmiskunta tai yksittäiset ihmiset eivät ole tietoisesti lähteneet muuttamaan (...) ilmastoa. Päinvastoin ilmastonmuutos on syntynyt teollistumisen ja nykyisen elämäntyylimme tahattomana – ja pitkään myös tiedostamattomana – sivuvaikutuksena. Koska omien tekojemme kausaalinen vaikutus sekä niiden tahallisuus tai tahattomuus on luonnollisesti keskiössä arvioidessamme omaa vastuutamme, mahdollinen osallisuutemme vahingon tuottamiseen jää helposti vähemmälle huomiolle. -/- Keskityn tässä artikkelissa osallisuusvastuun (complicity) käsitteeseen ja argumentoin samalla liian yksilökeskeistä ajattelua vastaan. Kollektiivinen toimijuus on otettava huomioon siinä missä yksilökeskeinenkin. Vastuunkantaja ja vastuun peruste ovat analyyttisesti erillisiä käsitteitä, ja niiden tarkastelu voi valottaa vastuukeskustelua ilmastonmuutoksesta. Vastuun peruste voi olla yksilöllinen silloinkin, kun vastuunkantaja on kollektiivinen. Lisäksi argumentoin, että vastuusta puhuttaessa ei riitä katsoa asiaa vain toimijan itsensä kannalta, vaan myös uhrin ja sivustakatsojan näkökulmat on otettava huomioon. Vasta kun vastuukäytäntöjä tarkastellaan ihmisten keskinäisten (usein monimutkaisten) verkostojen ja linkitysten kautta, voidaan saada tasapainoinen kuva vastuumme määrästä ja sen rajoista. -/- Yksilön vastuu ei poista vastuuta kollektiiveilta, kuten valtioilta, ja voimme tehokkaimmin hillitä ilmastonmuutosta esimerkiksi lainsäädännön kautta. Ennen kuin kollektiiviset ratkaisut ilmastonmuutoksen hillitsemiseksi saadaan toimimaan, vastuu palautuu kuitenkin yksilöille. Vastuun peruste on aina yksilötasolla ja sitä voidaan ainoastaan delegoida kollektiiveille. Ilmastonmuutoksen kohdalla delegointi ei ole vielä toiminut. (shrink)

The European Union has styled itself a global leader in climate action. In so doing, it presents itself as responding to science and public concern and its historic responsibilities. In terms of its means of response, the European Union’s emissions trading scheme has been the primary instrument. A rational response to liberal economic theory, the EU ETS is often trumpeted as a cost-effective success story internally and as a model to be adopted externally. This optimistic narrative is challenged herein.

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)

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.

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.

Climate change's impact on investor behavior is a scantly investigated area in finance. This paper examines the performance of socially responsible exchange trade funds (ETFs) concerning conventional ETFs, in response to climate change events. We proxy climate change signals with a list of natural disaster events that NASA scientists relate to climate change. We contribute to existing literature, by using a very extensive information set of ETF strategies, not influenced by rating agencies' (...) subjective evaluation policies, and covering almost 90% of the universe of worldwide sustainability thematic-oriented ETFs. This sample allows us to identify the socially responsible investment behavior in response to unpredictable climate change shocks. Our identification strategy accounts for endogeneity concerns and relies on two-stage least square (2SLS) approach finding that responsible investors react to climate change events by purchasing socially responsible investments. The relationship between climate change signals and return of investment in themes linked to the development of sustainability is positive. Interestingly enough, the sign of this relationship is different, when we disentangle the empirical results according to the asset type, confirming that investors shift their investments from equity funds to bond funds when market sentiment worsens. Our results indicate that policymakers should increase the support of firms adopting environmentally conscious business practices, while managers should boost a sustainable business strategy.

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.

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 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)

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.

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.

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.

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).

Climate change confronts us with our most pressing challenges today. The global consensus is clear that human activity is mostly to blame for its harmful effects, but there is disagreement about what should be done. While no shortage of proposals from ecological footprints and the polluter pays principle to adaptation technology and economic reforms, each offers a solution – but is climate change a problem we can solve? In this provocative new book, these popular proposals for (...) ending or overcoming the threat of climate change are shown to offer no easy escape and each rest on an important mistake. Thom Brooks argues that a future environmental catastrophe is an event we can only delay or endure, but not avoid. This raises new ethical questions about how we should think about climate change. How should we reconceive sustainability without a status quo? Why is action more urgent and necessary than previously thought? What can we do to motivate and inspire hope? Many have misunderstood the kind of problem that climate change presents – as well as the daunting challenges we must face and overcome. Climate Change Ethics for an Endangered World is a critical guide on how we can better understand the fragile world around us before it is too late. This innovative book will be of great interest to students and scholars of climate change, climate justice, environmental policy and environmental ethics. "This book offers a rare combination of tough-mindedness, analytic rigor, and passion as it tackles the greatest challenge of our time―climate change. For Brooks, it’s past time to acknowledge that climate change cannot be solved though the careful selection of good polices. Climate change is an unavoidable tragedy that we must endure but may be able to survive. Offering a program that emphasizes flexibility and adaptation, Brooks brings original insights to a debate that too long has been bogged down in wishful thinking and empty scholasticism."

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)

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)

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)

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 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)

Philosophers of science have offered various accounts of climate model evaluation which have largely centered on model-fit assessment. However, despite the wide-spread prevalence of process-based evaluation in climate science practice, this sort of model evaluation has been undertheorized by philosophers of science. In this paper, I aim to expand this narrow philosophical view of climate model evaluation by providing a philosophical account of process evaluation that is rooted in a close examination of scientific practice. I propose dynamical (...) adequacy as a metric by which scientists test and evaluate models that represent and produce key regional climate processes and features. I argue that process-based evaluation confirms the adequacy of a regional climate model for simulating and predicting future changes of a specific regional climate feature. I offer a case study of how, in practice, scientists establish the reliability of model projections by assessing the dynamical adequacy of such models. I also show how process-based evaluation mitigates some well-known shortcomings of model-fit assessment and supports the adequacy and reliability of climate model projections against philosophical objections, like confirmational holism. Such adequacy is especially important for decision makers who need reliable regional model projections to guide their climate change mitigation and adaptation policies. (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.

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)

Does the receipt of benefits from some common resource create an obligation to contribute toward its maintenance? If so, what is the basis of this obligation? I consider whether individual contributions to climate change can be impugned as wrongful free riding upon the stability of the planet's climate system, when persons enjoy its benefits but refuse to bear their share of its maintenance costs. Two main arguments will be advanced: the first urges further modification of H.L.A. Hart’s (...) “principle of fairness” as the basis for demanding that would-be free riders pay their fair share in the context of climate change, while the second claims that remedial action on climate change is better captured through collective action analysis than through harm principles that seek to connect individual actions to bad environmental outcomes.

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.

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 – 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 challenges the means of subsistence for many, particularly in the Global South. To respond to the challenges of climate change, countries increasingly resort to resettling those most affected by land erosion, heat, drought, floods, and the like. In this article, I investigate to what extent resettlement can compensate for the harm that climate-induced migration brings. The first harm I identify is that to individual autonomy. I argue that climate change changes the (...) options of those affected by it to the point that the decision to migrate can no longer count as a voluntary one. In some cases, I argue, the conditions of climate change coerce individuals. Second, I suggest that climate-induced migration severs the ties to territory, explaining the constitutive nature of such ties for accounts of individual autonomy. Third, I argue that severing ties with a traditional and historical territory challenges the capacity to imagine a future for individuals. I conclude that resettlement, even if actively planned and chosen, possibly providing gains in individual well-being and human flourishing, nevertheless harms individual autonomy interests. (shrink)
