Using an analogy in science and everyday life is a double-edged sword because they are accompanied by alternative ideas, in addition to scientific concepts. Schools and public education explain global warming by making a common analogy between this phenomenon and greenhouse effects. Unfortunately, this analogy sometimes produces various incorrect explanatory mental models. To construct a correct understanding of global warming, it is necessary: first, to investigate the attributes of analogical reasoning; second, to understand these features by restructuring the (...) class='Hi'>greenhouse analogy; and third, to explore the problems and benefits of the greenhouse analogy. The characteristics of relations, rather than objects, must be mapped according to the principle of systematicity, but the public tends to preserve the attributes of the base domain, which is mapped relatively easily. In conclusion, certain facets of the prevailing greenhouse analogy cause a distorted public view of climate change. We must use the greenhouse analogy and yet simultaneously emphasize the relations and attributes highlighted and hidden in the analogy during evaluation. (shrink)

Evidence provided by the scientific community strongly suggests that limits should be placed on greenhouse gas emissions. This means that states, firms, and individuals will have to face potentially serious burdens if they are to implement these limits. Which principles of justice should guide a global regime aimed at reducing greenhouse gas emissions originating from human activities, and most notably from CO2emissions? This is both a crucial and difficult question. Admittedly, perhaps this question is too ambitious, given the (...) uncertainties and complexities characterizing the issue of climate change. Yet, rather than listing them all at this stage, let us address the question in a straightforward manner, introducing some of these complexities as the need arises. (shrink)

National greenhouse-gas accounting should reflect how countries’ policies and behaviours affect global emissions. Actions that contribute to reduced global emissions should be credited, and actions that increase them should be penalized. This is essential if accounting is to serve as accurate guidance for climate policy. Yet this principle is not satisfied by the two most common accounting methods. Production-based accounting used under the Kyoto Protocol does not account for carbon leakage — the phenomenon of countries reducing their domestic emissions (...) by shifting carbon-intensive production abroad1. Consumption-based accounting2,3 does not credit countries for cleaning up their export industries, and it also punishes some types of trade that could contribute to more carbon efficient production worldwide. We propose an improvement to consumption-based carbon accounting that takes technology differences in export sectors into account and thereby tends to more correctly reflect how national policy changes affect total global emissions. We also present empirical results showing how this new measure redraws the global emissions map. (shrink)

This paper explores factors shaping perceptions of Greenhouse Gas Removal (GGR) amongst a range of informed stakeholders, with a particular focus on their role in future social and political systems. We find considerable ambivalence regarding the role of climate targets and incumbent interests in relation to GGR. Our results suggest that GGR is symbolic of a fundamental debate – occurring not only between separate people, but sometimes within the minds of individuals themselves – over whether technological solutions represent a (...) pragmatic or an unethical strategy. We present the idea of a ‘Monsanto effect’, whereby an entirely separate debate taps into deeper narratives and becomes so pervasive that it spills over into a new topic area. Our findings have signifi-cant implications for extant and emergent climate policy as they suggest that, in addition to the considerable practical challenges facing large-scale GGR deployment, there is a deeper psychological challenge in that actors are themselves conflicted about the fundamental desirability of GGR.

In this book some options concerning the greenhouse effect are assessed from a welfarist point of view: business as usual, stabilization of greenhouse gas emissions and reduction by 25% and by 60%. Up to today only economic analyses of such options are available, which monetize welfare losses. Because this is found to be wanting from a moral point of view, the present study welfarizes (among others) monetary losses on the basis of a hedonistic utilitarianism and other, justice (...) incorporating, welfare ethics. For these welfarist evaluations information about the social consequences of the four options are collected from the literature and eventually corrected; then the consequences for individual well-being are assessed based on psychological research about well-being dependent on the social situation of the individual; finally the aggregation formulas of the respective welfare ethics are applied to these data. Assessments by other types of ethics, e.g. Kantian ethic, are included. The strongest abatement option is found to be optimum with great unanimity. - In addition a cost-welfare analysis of greenhouse gas abatement is undertaken revealing efficient cost-welfare ratios for these measures and the most efficient ratio for the strongest option. - A final, more theoretical part discusses the moral obligations following from such evaluations. The notion of 'moral obligation' is explained in a way that, apart from moral goodness of the required act, reinforcement by formal or informal sanctions is another necessary condition for moral obligations. This leads to a conception of a historical morality according to which the demands of morality rise in the long run. Applying this conception to the greenhouse effect implies that presently we have the moral duty to raise the standards of greenhouse gas abatement as much as is politically feasible. (shrink)

For the first time Entropy has been completely revised and updated to include a new subtitle which reflects the expanded focus on the greenhouse effect--the largest crisis ever to face mankind.

How should the task of containing the global greenhouse effect be divided internationally, especially as between developed and developing countries? It is hard to overestimate the importance of this question. When George W. Bush, in agreement with a 95-0 vote of the U.S. Senate, refused to sign on even to the utterly inadequate constraints of Kyoto, he did not affirm junk science; he rejected an arrangement that "exempts 80% of the world, including major population centers such as China (...) and India ..."1 It is also hard to be too cynical about the interests and powers that will largely shape any ultimate greenhouse regime. Above all, U.S. political leaders will (in effect, whatever they say to others and to themselves) resist arrangements that help humanity but advance the time when the rising star of Chinese power overtakes declining U.S. power. Still, the growing social movement concerned with the greenhouse effect can have some impact, by increasing the reputational costs of immoral choices. I will try to contribute to this supplement to power politics and disasters by defending a view of cogent reasoning over the fair division of tasks among the world's people in responding to the challenge of global climate change.

The choice of greenhouse gas emissions accounting method is important because it affects the way climate burdens are allocated between states. This paper investigates the significance of state jurisdiction for this choice. It assesses three arguments from jurisdiction against consumption-based emissions accounting: the fairness argument from retrospective responsibility; the fairness argument from prospective responsibility; and the effectiveness argument. It argues that former two arguments fail since attributing emissions to importing states neither unfairly blames these states nor asks too much (...) of them. However, the effectiveness argument provides a strong potential reason against consumption-based emissions accounting. To the extent jurisdictional control is needed to reduce some emissions, and production-based accounting incentivizes states to reduce these emissions, there is a reason of environmental effectiveness for sticking with production-based accounting.

The declining role of the state in world economic affairs and the increasing reach of transnational corporations to various parts of the world pose a serious challenge to the effectiveness and success of international environmental treaties. With the further integration of the global economy and the rise of economic actors that operate and conduct their business without regard to national boundaries, cost-benefit analyses of economic development and environmental impact become problematic. For instance, are national states responsible for the pool of (...) carbon emissions within their borders or do the foreign owners of carbon-emitting infrastructure and production or the consumers of goods manufactured by transnational corporations in Third World countries hold a share of the responsibility for the emissions created? These and other related issues, such as the promotion of equity and justice, are the main themes of this article. (shrink)

The increasing prevalence of ecologically sustainable products in consumer markets, such as organic produce, are generally assumed to curtail anthropogenic impacts on the environment. Here I intend to present an alternative perspective on sustainable production by interpreting the relationship between recent rises in organic agriculture and greenhouse gas emissions from agricultural production. I construct two time series fixed-effects panel regressions to estimate how increases in organic farmland impact greenhouse gas emissions derived from agricultural production. My analysis finds that (...) the rise of certified organic production in the United States is not correlated with declines in greenhouse gas emissions derived specifically from agricultural production, and on the contrary is associated positively overall agricultural greenhouse gas emissions. To make sense of this finding, I embed my research within the conventionalization thesis. As a result I argue that the recent USDA certification of organic farming has generated a bifurcated organic market, where one form of organic farming works as a sustainable counterforce to conventional agriculture and the other works to increase the economic accessibility of organic farming through weakening practice standards most conducive to reducing agricultural greenhouse gas output. Additionally, I construct my own theoretical framework known as the displacement paradox to further interpret my findings. (shrink)

The disclosure of corporate environmental performance is an increasingly important element of a firm’s ethical behavior. We analyze how the legal origin of foreign institutional investors affects a firm’s voluntary greenhouse gas emissions disclosure. Using a large sample of firms from 36 countries, we show that foreign institutional ownership from civil law countries improves the scope and quality of a firm’s greenhouse gas emissions reporting. This relation is robust to addressing endogeneity and selection biases. The effect is (...) more pronounced in firms from non-climate-sensitized countries, for which the gap between firms’ environmental standards and investors’ environmental targets is potentially larger, and in less international firms. Firms with a higher level of voluntary greenhouse gas emissions disclosure also exhibit higher valuations. (shrink)

climate scientists have been engaged in a decades-long debate over the standing of satellite measurements of the temperature trends of the atmosphere above the surface of the earth. This is especially significant because skeptics of global warming and the greenhouse effect have utilized this debate to spread doubt about global climate models used to predict future states of climate. I use this case from an under-studied science to illustrate two distinct philosophical approaches to the relation among data, scientists, (...) measurement, models, and theory. I argue that distinguishing between 'direct' empiricist and 'complex' empiricist approaches helps us understand and analyze this important scientific episode. I also introduce a complex empiricist account of testing and evaluation, and contrast it with the basic Hypothetico-Deductive approach to the climate models used by the direct empiricists. This more developed complex empiricist apporach will serve philosophy of science well, as computational models become more wide-spread in the sciences. (shrink)

Industrial emissions of greenhouse gases are significant contributors to climate change, which poses a grave threat to social and economic systems. Our understanding of what might drive firms to reduce their emissions of these gases, however, is incomplete, and it is not clear that the knowledge gained from other environmental issues will readily apply to these emissions. We argue and find that indicators of environmental injustice previously shown to relate to toxic pollutants, for example, are poor predictors of (...) class='Hi'>greenhouse gas emissions. Instead, we show that the degree of belief in and concern about climate change in a local community is a significant predictor of the facility’s rate of emission improvements. Furthermore, we find that beliefs at both the facility and headquarter communities influence emission reduction, and that those effects are substitutes for each other. (shrink)

Rebound effects on the consumer level occur when consumers’ realized greenhouse gas emission savings caused by behaviors that might be beneficial to the environment are lower than their potential greenhouse gas emission savings because the savings are offset by behavioral adjustments. While previous literature mainly studied the economic mechanisms of such rebound effects, research has largely neglected the moral-psychological mechanisms. A comprehensive conceptualization of rebound effects on the consumer level can help fill this void and stimulate more empirical (...) research in this relevant area. To this end, the paper introduces three focal dimensions of rebound effects on the consumer level: mechanism of rebound effects, product category, and consumption context. Based on this conceptualization, and integrating assumptions from the theory of moral licensing, the theory of categorization, and the construal level theory, this paper further refines the conceptualization of the moral component as an explanatory factor for rebound effects and highlights that the moral-psychological mechanisms of indirect rebound effects are more complex and diverse than the economic mechanisms. The paper outlines promising directions for future studies considering the different quantification and characteristics of economic and moral currencies that explain rebound effects on the consumer level and the strategic categorization of products and consumption contexts.

While states have agreed to substantial reduction of emissions in the Paris Agreement, the success of the Agreement strongly depends on the cooperation of large Multinational Corporations. Short of legal obligations, we discuss the effectiveness and moral legitimacy of voluntary approaches based on naming and shaming. We argue that effectiveness and legitimacy are closely tied together; as voluntary approaches are the only alternative to legally imposed duties, they are most morally defensible particularly if they would be the most effective in (...) reducing the harmful greenhouse gases. Shaming could be made effective if states could prompt more corporations to accept voluntary cuts with high gains—such as public acknowledgements—and high losses, such as reporting on noncompliance and public exposure, along with some kind of condemnation. An important challenge of such voluntary approaches is how to ensure compliance with the agreed upon commitments, while avoiding greenwashing or selective disclosure. Certain institutional arrangements are inevitable, including an independent measurement, monitoring and verification mechanism. In this paper, we discuss the potentials and ethical pitfalls of shaming as a strategy when corporations have a direct relationship with consumers, but also when they are in a relationship with governments and other corporations.

What are we doing to our climate? Emissions from fossil fuel burning have raised carbon dioxide concentrations 35 percent higher than in the past millions of years. This increase is warming our planet via the greenhouse effect. What is climate change doing to and for us? Dry regions are drier and wet ones wetter. Wildfires have increased threefold, hurricanes more violent, floods setting record heights, glaciers melting, and seas rising. Parts of Earth are increasingly uninhabitable. Climate change requires (...) us to act as a global community. Climate justice enjoins emitters to pay the social‐environmental costs of fossil fuel burning. This would expedite green solar, wind, and next‐generation nuclear energy sources. Individuals should conserve resources, waste less food, and eat a plant‐rich diet. (shrink)

The current debate surrounding the implementation of the Kyoto Treaty raises several issues that ought to be of interest to social and political philosophers. Proponents and critics alike have invoked ideas of fairness in justification of their positions. The two distinct conceptions of fairness that are involved in this debate—one of fair shares, and another of fair burdens—helpfully illuminate the proper role of fairness in designing an equitable and effective global climate regime. In this paper, I critically examine the idea (...) of fairness as manifest in two contending visions of the proper international response to mounting evidence that human activity is causing climate change, and that harm from this change is likely to exacerbate existing inequalities. In addition, I recommend one idea of fairness (the fair shares conception) and the political program that it implies. (shrink)

In the traditional case, the uncertainty of the ambient temperature measured by the experiential distributed sensor is considered. In this paper, a model based on the moving least square method in the fusion algorithm is proposed to study the optimal monitoring point of the sensor in the greenhouse and determine the most suitable installation position of the sensor in the greenhouse to improve the control effect of the temperature control device of the system. MATLAB simulation software is (...) used to simulate each working condition of the greenhouse. Temperature data measured at 15 locations in the greenhouse were used to evaluate all possible combinations of monitoring locations and to estimate the optimal location for indoor temperature sensors. Compared with the traditional method, the error is reduced to 0.373, and the data are more accurate. (shrink)

Arbuscular mycorrhizal fungi are considered as a potential biotechnological tool for improving phytostabilization efficiency and plant tolerance to heavy metal-contaminated soils. However, the mechanisms through which AMF help to alleviate metal toxicity in plants are still poorly understood. A greenhouse experiment was conducted to evaluate the effects of two AMF species on the growth, Pb accumulation, photosynthesis and antioxidant enzyme activities of a leguminous tree at Pb addition levels of 0, 500, 1000 and 2000 mg kg-1 soil. AMF symbiosis (...) decreased Pb concentrations in the leaves and promoted the accumulation of biomass as well as photosynthetic pigment contents. Mycorrhizal plants had higher gas exchange capacity, non-photochemistry efficiency, and photochemistry efficiency compared with non-mycorrhizal plants. The enzymatic activities of superoxide dismutase, ascorbate peroxidases and glutathione peroxidase were enhanced, and hydrogen peroxide and malondialdehyde contents were reduced in mycorrhizal plants. These findings suggested that AMF symbiosis could protect plants by alleviating cellular oxidative damage in response to Pb stress. Furthermore, mycorrhizal dependency on plants increased with increasing Pb stress levels, indicating that AMF inoculation likely played a more important role in plant Pb tolerance in heavily contaminated soils. Overall, both F. mosseae and R. intraradices were able to maintain efficient symbiosis with R. pseudoacacia in Pb polluted soils. AMF symbiosis can improve photosynthesis and reactive oxygen species scavenging capabilities and decrease Pb concentrations in leaves to alleviate Pb toxicity in R. pseudoacacia. Our results suggest that the application of the two AMF species associated with R. pseudoacacia could be a promising strategy for enhancing the phytostabilization efficiency of Pb contaminated soils.

To reduce global greenhouse gas emissions in order to limit global warming to 1.5°C, individuals and households play a key role. Behavior change interventions to promote pro-environmental behavior in individuals are needed to reduce emissions globally. This systematic literature review aims to assess the a) evidence-based effectiveness of such interventions and b) the content of very successful interventions without limiting the results to specific emitting sectors or countries. Based on the “PICOS” mnemonic and PRISMA statement, a search strategy was (...) developed, and eligibility criteria were defined. Three databases were searched to retrieve and review potential literature. As a result, 54 publications from 2010 to 2021 were included in the analysis. The results show that most interventions only have small positive effects or none at all. A total of 15 very successful interventions focused on the sectors of mobility, energy, and waste and incorporated improved structures, education, feedback, enablement or made the sustainable option the default. Six evidence-based recommendations for content, timing, and setting are deducted and given for interventions on enhancing pro-environmental behavior. In summary, although the various interventions and intervention types to promote PEB differ in their effectiveness, very successful interventions have common elements. Future research should focus on high-/low-impact and high-/low-cost behavior to develop interventions that aim at high-impact but low-cost behavior changes, or avoid low-impact but high-cost behavior.

Wynes and Nicholas (2017) argue that the most effective action to reduce individual greenhouse gas (GHG) emissions is to have one fewer child. We raise methodological concerns about the way in which the authors attribute responsibility for emissions: they rely on multiple counting when calculating the emissions of future generations, and they exclude scenarios in which global emission trajectories become net-zero or negative. This may distort recommendations from policy makers and educators who rely on their study. We propose an (...) alternative way of attributing responsibility that avoids multiple counting. Investigating the implications of having children under this proposal with regards to the full range of different scenarios, including likelihood analyses, calls for further studies. (shrink)

A cost-benefit analysis of the AirCare program in the province of British Columbia on the basis of emissions cost factors from the literature showed a benefit outweighing the cost. Furthermore, a cost-effectiveness analysis comparing the AirCare program with a hybrid-car rebate program revealed that the AirCare program is more effective in reducing emissions of major air pollutants such as NOx, hydrocarbons, and CO. However, the hybrid-car rebate program contributes significantly to the reduction of greenhouse gas emissions because of much (...) greater fuel efficiency, although its contribution to reducing emissions of major air pollutants is small compared with that of the AirCare program. Both the AirCare program and the hybrid-car program are therefore essential to addressing both local air quality improvement and global warming issues, and the programs complement each other.

This Article presents an innovative institutional strategy for global climate protection, quite distinct from, but ultimately complementary to and supportive of the currently stalled UNFCCC climate treaty negotiations. The bottom-up strategy relies on a variety of smallerscale transnational cooperative arrangements, involving not only states but sub-national jurisdictions, firms, and CSOs, to undertake activities whose primary goal is not climate mitigation but which will achieve greenhouse gas reductions as an inherent byproduct. This strategy avoids the inherent problems in securing an (...) enforceable treaty to secure the global public good of climate protection by mobilizing other incentives - including economic self-interest, energy security, cleaner air, and furtherance of international development - to motivate such actors to cooperate on actions that will also benefit the climate. These bottom-up regimes will contribute to global climate action not only by achieving emissions reductions in the short-term, but also by linking the bottom-up regimes to the UNFCCC system through greenhouse gas monitoring and reporting systems. In these ways, the bottom-up strategy will help secure eventual agreement on a global climate treaty. (shrink)

The prospect of climate change due to human activities has put the question of inter- and intragenerational justice or equity in matters of common concern on the global agenda. This article will focus on the question of intragenerational justice in relation to these issues. This involves three basic questions. Firstly, the question of which distributive criteria may be relevant in the distribution of the goods and bads related to the increasing greenhouse effect. A series of criteria are discussed (...) in relation to different understandings of the problem. The second question is which kind of relationship the global partnership is or should be considered to be in issues of common concern. It is argued that various understandings of the global partnership can be expected to result in the use of different criteria. This diversity leads us to the third question concerning the possibility of identifying an overall social ideal which can be used in cases where several different criteria may be useful. I shall discuss one such ideal in particular, namely the ideal of complex equality. In the concluding remarks it is argued that a distribution of emission quotas to countries in accordance with population size is a reasonable starting point for an equitable solution, although it involves various problems of application.

The transport sector is one of the largest sources of greenhouse gas emissions in New Zealand. To address this issue, the government is planning a set of actions to be implemented in the next 15 years. One of these actions deals with transport emissions and targets for a reduction in light vehicle travel. However, to achieve this goal, there is a need for both an updated assessment of effective interventions and an analysis of their relevance and applicability to the (...) New Zealand context. This report seeks to close the gap by conducting a narrative literature review of a collection of existing literature, supplemented with some targeted searches. With the focus on evidence relevant to New Zealand’s largest and fastest growing urban environments, the report identified 24 publicly available research outputs from around the world (mainly from Western European countries). The papers assessed differ not only in the type of research method and analysis applied but also the form of intervention (s) evaluated, the duration of the intervention and follow-up periods, the characteristics of the population groups or intervention sites studied, the measures, results and metrics relevant to New Zealand, and the outcomes of the interventions. Although these differences may represent a challenge in terms of comparability and transferability, they also provide opportunities and lessons for policy-and decision-makers. Finally, the report discusses the implications of the review and its findings and provides some directions and recommendations for future research, policy and practice for the measurement and evaluation of interventions.

. With an overall objective of establishing association between air pollutants and incidence of respiratory diseases, the environmental professionals and medical practitioners have made significant contribution, using statistical mechanics in modelling epidemiological data, population characteristics, and pollution parameters. Broadly speaking, the studies have shown that the increase in vehicular traffic has been one of the causes of respiratory diseases. However, the WHO Centre for Environment and Health, Europe in its 2005 document states: “There is little evidence for a causal relationship (...) between asthma prevalence/incidence and air pollution in general, though the evidence is suggestive of a causal association between the prevalence/incidence of asthma symptoms and living in close proximity to traffic”. Decision making process in a real world is invariably based on perceptions which are expressed in words or may be in numeric terms and not in probability terms. In the paper, we made an attempt to model the perceptions of experienced pulmonologists in arriving at their combined degree of belief/plausibility/ignorance for all the possible combinations of identified respiratory diseases, using evidence theory and fuzzy relational calculus without collecting sizeable parametric data accumulated over a period of years. Tightening pollution norms by the regulatory authorities is an overall objective of the global efforts on greenhouse gases reduction in general, and air pollution mitigation in particular. The concept of solar battery operated electric vehicles for road transport is advocated, initially for two/three wheelers, and extending it to four wheelers, especially in the developing countries.

The concept of 'sustainable development' as used by the Brundtland Commission was meant to separate environmental policy from distributional conflicts. Increases in income sometimes are beneficial for the environment, but higher incomes have meant higher emissions of greenhouse gases, and higher rates of genetic erosion. In the aftermath of the Rio conference of June 1992, this article analyses some unavoidable links between distributional conflicts and environmental policy. Often, environmental movements have tried to keep environmental resources and services outside the (...) market, but there are now attempts to establish property rights on, and to give money values to environmental resources and services, such as agricultural genetic resources and the CO2 absorption facility provided by the oceans and new vegetation. European 'green' proposals to impose an 'eco-tax', and proposals from India to create a world market for CO2 emission permits are considered. The issue raised by the growing Third World agroecology movement, of payment of 'farmers' rights' for in situ agricultural biodiversity is discussed. The article includes a short discussion of the North American free trade agreement between Mexico and the USA, in so far as it involves so-called 'ecological dumping', i.e. trading at values which do not include environmental costs. In the last sections, the article asks how prices in ecologically-extended markets would be formed, how much such prices will depend on distribution, and how much such payments would change distribution of income. Environmental movements of the Poor are faced with the dilemma of keeping environmental resources and services out of the market, or else asking for property rights to be placed on them. (shrink)

An economically viable and environmental friendly method of generating hydrogen for fuel cells is by the reaction of certain metals with steam, called metalsteam reforming (MSR). This technique does not generate any toxic by-products nor contributes to the undesirable greenhouse effect. From the standpoint of favorable thermodynamics, total environmental benignity, and attractive economics, iron appears to be the metal of choice for such a process. An inexpensive source of iron for the MSR is the steel industry's mill-scale waste (...) via hydrogen and carbothermic reduction, both of which are energy-intensive processes. These have been eliminated by a novel, solution-based room temperature technique producing nanoscale iron, thus obviating the sintering of iron or iron oxide and deactivation during the cyclic operation of MSR. Some preliminary results are presented of an investigation aimed at converting the mill-scale waste into nanoscale iron, which was subsequently used in generating hydrogen for proton exchange membrane fuel cells.

Hans Jonas and Arne Næss have argued that philosophers need not be concerned with natural sciences even when they talk about enviromental issues like global warming (§1). However, believing sciences blindly is in itself unphilosophical.

One is about the industrial revolutions (§§5-9); the other is about the (...) class='Hi'>greenhouse effect (§§11-20). Through this consideration, it will be revealed: the views of the Establishment are not at all absolute; there still remains room to reconsider them. (shrink)

The importance of the specifi relationship between the US and the EU is determined by the role they play in solving international problems. The purpose of the article is to study the impact of common and distinctive position in US and EU foreign policy on the development of their relations and ability to effectively solve the world’s problems. At the beginning of the XXI century relations between the US and the EU have been developing in various spheres of foreign policy. (...) The priorities were security cooperation, the fiht against international terrorism and the development of economic relations. US and EU are mutually benefiial and priority partners for each other. This is determined in the foreign policy instruments of the United States and the European Union. However, this does not preclude the existence in the United States and the European Union different approaches to solving international problems and competition between them. The biggest differences between the US and the EU are shown in approaches to the settlement of military conflcts, the fiht against global warming and the greenhouse effect. The largest component of competitive relations is manifested in the development of the Arctic region. The US seeks to engage the EU foreign policy implementation taking into account American interests. However, at the beginning of the XXI century the EU had its own foreign policy program. The EU has an unhappy tendency towards US methods of solving world problems and unilateral actions in the international arena. The bipolar system was dominated by bilateral cooperation between the US and individual states of the European Union, but during the presidency of Barack Obama, the United States prefer relations with European politicians who represent the agreed position of 28 EU member states. The US in implementing its foreign policy should take into account the position of individual states and the European Union as a whole entity. This affects the process of solving international problems. Despite the existence of contradictions in the relations of the United States and the European Union, cooperation will continue to contribute to this long-term relationship, similarities in approaches to building political and economic systems and similarities in mentality.

The goal of this study was to explore two accounts for why sketching during learning from text is helpful: sketching acts like other constructive strategies such as self-explanation because it helps learners to identify relevant information and generate inferences; or that in addition to these general effects, sketching has more specific benefits due to the pictorial representation that is constructed. Seventy-three seventh-graders were first taught how to either create sketches or self-explain while studying science texts. During a subsequent learning phase, (...) all students were asked to read an expository text about the greenhouse effect. Finally, they were asked to write down everything they remembered and then answer transfer questions. Strategy quality during learning was assessed as the number of key concepts that had either been sketched or mentioned in the self-explanations. The results showed that at an overall performance level there were only marginal group differences. However, a more in-depth analysis revealed that whereas no group differences emerged for students implementing either strategy poorly, the sketching group clearly outperformed the self-explanation group for students who applied the strategies with higher quality. Furthermore, higher sketching quality was strongly related to better learning outcomes. Thus, the study's results are more in line with the second account: Sketching can have a beneficial effect on learning above and beyond generating written explanations; at least, if well deployed.

In a certain sense, uncertainty andignorance have been recognized in science andphilosophy from the time of the Greeks.However, the mathematical sciences have beendominated by the pursuit of certainty.Therefore, experiments under simplified andidealized conditions have been regarded as themost reliable source of knowledge. Normally,uncertainty could be ignored or controlled byapplying probability theory and statistics.Today, however, the situation is different.Uncertainty and ignorance have moved intofocus.

Detuning the climate: Thinking about climate change with Heidegger, Sloterdijk and Blok This paper investigates the phenomenological importance of anthropogenic climate change by focussing on the double meaning of ‘climate’, namely (1) average weather condition and (2) social mood or atmosphere (e.g. political climate). The relation between global heating and social mood or atmosphere is investigated through a rethinking of Martin Heidegger’s phenomenology of moods and Peter Sloterdijk’s elaboration of Heideggerian phenomenology into his philosophy of spheres. Guided by Heidegger’s insight (...) into the world disclosing function of moods, especially existential anxiety, we investigate whether climate anxiety has a similar disclosing function. We argue that climate anxiety involves an ecological world disclosure. We then turn to Sloterdijk’s elaboration of Heidegger’s phenomenology of moods into a wide-ranging theory of intersubjective attunement and life-world constitution in intersubjective ‘spheres’. Sloterdijk speaks of an intraspheric ‘greenhouse effect’, meaning that both the physical and the social climate within a sphere must be adequate for interhuman development. We argue that the catastrophic effects of runaway global heating threaten this intraspheric greenhouse effect, causing a fundamental increase in interhuman conflictuality. Finally, this paper also engages critically with Vincent Blok’s post-phenomenological, speculative ecology of the ‘earth in itself’ as necessitated by the disruptive event of climate change. Contra Blok it is argued that phenomenology is capable of uncovering the philosophical meaning of climate change, especially given the internal connection between climate as meteorological phenomenon and climate as world disclosing mood.

In discussions of moral responsibility for collectively produced effects, it is not uncommon to assume that we have to abandon the view that causal involvement is a necessary condition for individual co-responsibility. In general, considerations of cases where there is “a mismatch between the wrong a group commits and the apparent causal contributions for which we can hold individuals responsible” motivate this move. According to Brian Lawson, “solving this problem requires an approach that deemphasizes the importance of causal contributions”. Christopher (...) Kutz’s theory of complicitious accountability in Complicity from 2000 is probably the most well-known approach of that kind. Standard examples are supposed to illustrate mismatches of three different kinds: an agent may be morally co-responsible for an event to a high degree even if her causal contribution to that event is a) very small, b) imperceptible, or c) non-existent (in overdetermination cases). From such examples, Kutz and others conclude that principles of complicitious accountability cannot include a condition of causal involvement. In the present paper, I defend the causal involvement condition for co-responsibility. These are my lines of argument: First, overdetermination cases can be accommodated within a theory of coresponsibility without giving up the causality condition. Kutz and others oversimplify the relation between counterfactual dependence and causation, and they overlook the possibility that causal relations other than marginal contribution could be morally relevant. Second, harmful effects are sometimes overdetermined by non-collective sets of acts. Over-farming, or the greenhouse effect, might be cases of that kind. In such cases, there need not be any formal organization, any unifying intentions, or any other noncausal criterion of membership available. If we give up the causal condition for coresponsibility it will be impossible to delimit the morally relevant set of acts related to those harms. Since we sometimes find it fair to blame people for such harms, we must question the argument from overdetermination. Third, although problems about imperceptible effects or aggregation of very small effects are morally important, e.g. when we consider degrees of blameworthiness or epistemic limitations in reasoning about how to assign responsibility for specific harms, they are irrelevant to the issue of whether causal involvement is necessary for complicity. Fourth, the costs of rejecting the causality condition for complicity are high. Causation is an explicit and essential element in most doctrines of legal liability and it is central in common sense views of moral responsibility. Giving up this condition could have radical and unwanted consequences for legal security and predictability. However, it is not only for pragmatic reasons and because it is a default position that we should require stronger arguments (than conflicting intuitions about “mismatches”) before giving up the causality condition. An essential element in holding someone to account for an event is the assumption that her actions and intentions are part of the explanation of why that event occurred. If we give up that element, it is difficult to see which important function responsibility assignments could have. (shrink)

Il saggio introduce le tematiche di questo numero, soffermandosi in parti- colare sulla rilevanza etica e politica del cambiamento climatico. Dopo una rapida spiegazione dell'effetto serra naturale e artificiale, si ripercorrono le teorie che concepiscono il cambiamento climatico come un problema di giustizia distributiva. Secondo alcuni autori queste teorie non sono suffi- cienti per dare strumenti adeguati, perché il cambiamento climatico rappre- senta un problema etico nuovo, che richiede una strumentazione etica ine- dita. Il saggio approfondisce alcune delle caratteristiche nuove (...) dell'etica del cambiamento climatico, soprattutto in relazione all'impatto che le scelte presenti avranno sulla qualità della vita delle generazioni future.It is an introduction to the topic of the present issue of "La società degli in- dividui", dealing with the ethical and political relevance of climate change. After a brief account of the greenhouse effect, various approaches to clima- te change as a matter of distributive justice are considered. According to many authors, these approaches are inadequate, because climate change is a new issue, requiring new tools. The paper focusses on some of the new fea- tures of climate ethics, mainly in connection with the effects that our pre- sent choices may have on the quality of life of future generations. (shrink)

Nature always refers to something inasmuch as it relates to something else. This « something else » is highly variable. The role of Nature as the respondent of judgements which are both hierarchical and moral is always present in modern science, without thereby being deducible from modern science. Today it presents new contrasts, new oppositions which involve multiple natures, interlinked and historical, which does not result in anything like a neutral Nature. The best example, linked to the idea of Gaia, (...) is the greenhouse effect. Our interventions, even if they take place over a very short period of time, might disturb situations which arose over very long periods. Gaia is a new figure of Nature which must be respected because we are dependent on her, not in the sense that she must be respected as a goddess, but in the sense of her sensitivity. Now, a Nature that could thus be defined once and for all, with an identity that could be opposed to humanity’s, does not exist. Nature in the other sense does not exist objectively either, but is more interesting because it participates in human historicity. It exists in the sense in which it forces us to think, negotiate, take into account, imagine, take note without saying that Nature, too, thinks, negotiates, takes into account, imagines, and takes note. We must think and imagine with something that does not do so. This is the beginning of a culture of non-symmetry. If Nature as Gaia teaches us something, it is that we must take care : the fact the current regimen of interdependence suits us is in no way a privilege of this regiment. Gaia has no innate reason to care about us ; rather, we must care about her. Non-symmetry, then, is this interesting situation in which Nature interests us while we do not interest her. (shrink)

This study draws on neo-institutional theory to examine how and why corporate environmental management practices might affect environmental performance. It contributes to the literature by using a large, global data set to investigate the impact of 10 corporate environmental management practices on greenhouse gas emissions or emissions intensity. It focuses on greenhouse gas emissions which pose an existential threat to the people and planet, and the environmental management practices of corporations whose effectiveness has provoked cynicism and claims of (...) “greenwash”. Our results are based on a dynamic, robust and large-scale econometric analysis, which includes tests of association and Granger causation in comparison with earlier research. A key finding, which is of interest not only to the academic literature but also to policymakers and managers, is that environmental performance impacts environmental management practices but not vice versa, supporting the hypothesis that corporations adopt these practices as a symbolic legitimizing device rather than a genuine attempt derived from moral obligation to reduce their greenhouse gases or carbon intensity.
