This article documents the use of tipping points in climate change discourse to discuss their significance. We review the relevant literature, and discuss the popular emergence of tipping points before their adoption in climate change discourse. We describe the tipping point trend in mainstream US and UK print news media and in the primary scientific literature on climate change by replicating the methodologies of Oreskes [Oreskes, N., 2004. The scientific consensus on climate change. Nature 306, 1686] and Boykoff and Boykoff [Boykoff, M.T., Boykoff, J.M., 2004. Balance as bias: global warming and the US prestige press. Global Environmental Change 14, 125–136]. We then discuss the significance of climate change tipping points and their popular use in terms of generative metaphor. 相似文献

在气候系统五大圈层中,冰冻圈对气候变化高度敏感,近几十年来气候变暖已引起全球冰川、冻土、积雪和海冰等冰冻圈要素加速退缩,进而对区域水资源、生态环境、社会经济发展和人类福祉产生了深远影响。2018年10月,IPCC在韩国仁川公布了《全球1.5℃增暖特别报告》（SR1.5）。报告较系统地呈现了关于全球1.5℃温升目标的基本科学认知,并探讨了可持续发展及消除贫困目标下加强全球响应的路径。在冰冻圈相关内容方面,报告呈现了有关全球1.5℃和2℃温升下冰冻圈（主要是海冰和多年冻土）变化及其对大气圈、水圈、生物圈、岩石圈和人类圈影响的一些亮点结论,还关注了全球1.5℃和2℃温升下冰冻圈相关的气候变化热点（区）和地球系统临界因素。报告指出,随着温度不断升高,冰冻圈及其相关要素和热点（区）面临的风险将不断增加,但将全球温升控制在1.5℃而不是2℃或更高时的风险将大大降低。 相似文献

This paper reviews existing policy responses to rapid climate change and examines possible assumptions that underpin those responses. The analysis demonstrates that current policy responses to rapid climate change make unwarranted epistemological and ethical assumptions. Specifically, we argue that the assumptions about the possibility of predicting the climate system including tipping points linked to utilitarian ethical assumptions in the form of cost–benefit analysis are open to contestation and should be subject to global public debate. The paper considers alternative normative approaches and briefly proposes complementary policy responses. 相似文献

There is currently a huge gulf between natural scientists’ understanding of climate tipping points and economists’ representations of climate catastrophes in integrated assessment models (IAMs). In particular, there are multiple potential tipping points and they are not all low-probability events; at least one has a significant probability of being passed this century under mid-range (2–4 °C) global warming, and they cannot all be ruled out at low (<2 °C) warming. In contrast, the dominant framing of climate catastrophes in IAMs, and in critiques of them, is that they are associated with high (> 4 °C) or very high (> 8 °C) global warming. This discrepancy could qualitatively alter the predictions of IAMs, including estimates of the social cost of carbon. To address this discrepancy and assess the economic impact of crossing different climate tipping points, we highlight a list of scientific points that should be considered, at least in a stylised form, in simplified IAMs. For nine different tipping events, the range of expected physical climate impacts is summarised and some suggestions are made for how they may translate into socio-economic impacts on particular sectors or regions. We also consider how passing climate tipping points could affect economic growth. 相似文献

Business research has repeatedly been criticized for its lack of engagement with pressing issues such as climate change, despite a surge of publications on corporate sustainability topics in recent years. We are therefore interested in identifying the knowledge development and knowledge gaps in business scholarship on the relationship between firms, environment and society. This paper provides a systematic review of the corporate sustainability field in form of a bibliometric analysis based on citation data acquired from the Social Sciences Citation Index. The final dataset contained 3117 records published between 1953 and 2011. Our analysis shows that, over the last 50 years, the field of corporate sustainability has emerged from a few primary nodes of research and developed into four distinct conceptual genealogies: corporate social performance theory, stakeholder theory, a corporate social performance versus economic performance debate, and a greening of management debate. The results of our analysis suggest four key findings. First, the four genealogies only comprise a relatively narrowly focused research scope. Second, there is very little integration and citation of work in other disciplinary areas such as ecology or environmental science. Third, the existing literature has a strong focus on empirically examining the relationship between a firm's environmental and/or social performance and its financial performance. Finally, there is little consideration of managerial implications and consequences of climate change in the corporate sustainability literature to date. We suggest that while this may be a reflection of an insular field, it may also be a role played by the management literature turning away from problem based issues in favor of empirical results, theory building, and the identification of variables that influence firm profitability and can be subjected to direct managerial control. We conclude by outlining pathways for future research. 相似文献

An extensive literature shows that information-creating mechanisms enhance the transparency of and can support participation and compliance in international agreements. This paper draws from game theory, international relations, and legal scholarship to make the case for how transparency through policy surveillance can facilitate more effective international climate change policy architecture. I draw lessons from policy surveillance in multilateral economic, environmental, and national security contexts to inform a critical evaluation of the historic practice of monitoring and reporting under the global climate regime. This assessment focuses on how surveillance produces evidence to inform policy design, enables comparisons of mitigation effort, and illustrates the adequacy of the global effort in climate agreements. I also describe how the institution of policy surveillance can facilitate a variety of climate policy architectures. This evaluation of policy surveillance suggests that transparency is necessary for global climate policy architecture. 相似文献

Identifying historical patterns of fluctuation in climate change skepticism guides researchers, policy makers, and science communicators in efforts to catalyze change in the future. We analyzed data from 25 nationally representative polls collected in Australia from 2009 to 2019 (N = 20,655). Although it remains concerningly high, climate skepticism trended down in that 10-year period, particularly among conservatives. Multilevel analyses identified two variables that stood out as being relevant in explaining that trajectory. First, climate change skepticism was positively associated with support for conservative political parties in national polls. Second, climate change skepticism was negatively associated with the annual global temperatures the previous year. There was little evidence that climate change beliefs were associated with economic variables or with seasonal variations in temperature. Furthermore, there was only weak evidence that climate change beliefs were associated with national temperatures. This suggests that global temperatures in the previous year are impactful because of their informational value (as a communication heuristic for the urgency and immediacy of climate change) more so than for their experiential value (in the sense of people actually experiencing warmer weather). Importantly, the effect of previous global temperature was particularly pronounced among those with the strongest levels of skepticism: political conservatives. This suggests that rising global annual temperatures have the power to update beliefs among those most in need of converting to the climate cause. 相似文献

While corporate adaptation strategies in response to climate change have been characterized, the determinants of adaptation have not been comprehensively analyzed. Knowledge of these determinants is particularly useful for policy makers to provide favorable conditions in support of corporate adaptation measures. Based on unique data from a survey of Swiss ski lift operators, this paper empirically examines such determinants at the business level. Our econometric analysis with linear regression and count data models finds a positive influence of the awareness of possible climate change effects on the scope of corporate adaptation. Surprisingly, no significant influence of the vulnerability to climate change effects on the scope of adaptation could be found. Finally, the dependency on the affected business and the ability to adapt influence the specific strategic directions of corporate adaptation. 相似文献

Understanding of the human dimensions of climate change (HDCC) in glaciated mountain regions is limited by a deficit in systematically collated information on where, to what stressors, by whom, at what scale, and with what effect adaptation is occurring. This paper presents a systematic literature review of the recent English language peer-reviewed scholarship on adaptation in glaciated mountain regions. 4050 potentially relevant articles were examined, with 36 included for full review. Results indicate that scholarly investigation into adaptation in glaciated mountains is presently limited to only 40 % of countries with alpine glaciation. Seventy-four discrete adaptation initiatives were identified, with most occurring in Peru (28 %), Nepal (22 %) and India (17 %). Many documented adaptations were initiated in response to intersecting stressors related to cryospheric change and socio-economic development; were autonomous and initiated in reaction to experienced climatic stimuli; and were carried out at the individual, family, or community scale. The study contributes to an emerging literature tracking on-the-ground adaptation processes and outcomes, and identifies a need to raise the profile of human adaptation in glaciated mountain regions within the HDCC scholarship. A research agenda for addressing key knowledge gaps and questions is developed, providing a framework for future investigation. 相似文献

Human systems will have to adapt to climate change. Understanding of the magnitude of the adaptation challenge at a global scale, however, is incomplete, constrained by a limited understanding of if and how adaptation is taking place. Here we develop and apply a methodology to track and characterize adaptation action; we apply these methods to the peer-reviewed, English-language literature. Our results challenge a number of common assumptions about adaptation while supporting others: (1) Considerable research on adaptation has been conducted yet the majority of studies report on vulnerability assessments and natural systems (or intentions to act), not adaptation actions. (2) Climate change is rarely the sole or primary motivator for adaptation action. (3) Extreme events are important adaptation stimuli across regions. (4) Proactive adaptation is the most commonly reported adaptive response, particularly in developed nations. (5) Adaptation action is more frequently reported in developed nations, with middle income countries underrepresented and low-income regions dominated by reports from a small number of countries. (6) There is limited reporting on adaptations being developed to take advantage of climate change or focusing on women, elderly, or children. 相似文献

Two decades ago, an article was published in Global Environmental Change proposing the importance of place attachments, at local and global scales, for understanding human responses to climate change (Feitelson, 1991). Despite concluding that ‘studies of individual's attachment to place may provide important inputs for strategies to enhance the prospects for sharing the globe’ (p. 406, 1991), the article remains overlooked. This article takes up and extends Feitelson's argument for more systematic research on place attachments and climate change. First, the paper critically reviews interdisciplinary literature on place attachment and the related concept of place identity, drawing on scholarship in human geography, environmental and social psychology. The review identifies a lack of cross-disciplinary dialogue, as well as several limitations to the ways that scalar aspects have been researched. Second, climate change research, encompassing adaptation, mitigation and communication that has incorporated place related attachments and identities is critically reviewed; in particular, emerging research on the role of ‘psychological distance’ is critiqued. The article concludes with five recommendations for future research: to capture place attachments and identities at global as well as local scales; to integrate qualitative and quantitative methods that capture constructions of place as well as intensity of attachments and identifications; to investigate links between attachments, identities and collective actions, particular ‘NIMBY’ resistance to adaptation and mitigation strategies; to apply greater precision when investigating spatial frames of risk communication; and to investigate links between global attachments and identities, environmental worldviews and climate change engagement. Finally, the implications of such research for evaluating area-based climate interventions are discussed. 相似文献

Rancher and farmer perceptions of climate change in Nevada, USA 总被引：1，自引：1，他引：0
Farming and ranching communities in arid lands are vulnerable to the adverse impacts of climate change. We surveyed Nevada ranchers and farmers (n?=?481) during 2009–2010 to assess climate change related knowledge, assumptions, and perceptions. The large majority of this group agreed that we are in a period of climate change; however, only 29 % of them believed that human activity is playing a significant role. Female ranchers and farmers hold more scientifically accurate knowledge about climate change than do their male counterparts, regardless of Democratic or Republican affiliation. Partisan affiliation, political ideology, and gender have strong impacts on climate change knowledge and perceptions. Republican, conservative and male rural residents view climate change as a low national priority, less important to themselves, and less harmful to their communities. Female ranchers and farmers are more concerned about the negative impacts of climate change. We found that only 4 % of our subjects (n?=?299) attribute local environment changes to climate change or global warming. The knowledge gained from this study will help researchers and natural resource managers understand how to best communicate about climate change with rural communities, and support policy makers in identifying potentially effective adaptation and mitigation policies and outreach programs. 相似文献

Although climate policy diffusion is widely studied, we know comparatively little about how these global policies and the norms that surround them are used by various political actors seeking to advance their own agendas. In this article, we focus on how global climate norms are diffused differently at national and local scales and used to repoliticize or depoliticize climate change. We focus on the case of Turkey, which carries the stark contrast of showing willingness to achieve global climate goals in the international arena but less so in domestic politics and actions. The article employs a novel methodological approach, using topic modeling and network analyses on a range of climate change–related policy documents, and interviews with high-level officers, conducted at the three jurisdictional levels in Turkey. The findings reveal that although global climate policy is diffused to both national and local governments, it is used in different ways at these levels. The national government uses climate policy diffusion to depoliticize climate change by creating ad hoc climate coalitions and limiting local climate actions to seeking external climate-related funds. Meanwhile, the metropolitan municipalities replicate nationally adopted climate goals, whereas the district municipalities domesticate ambitious climate norms and repoliticize climate change via local climate entrepreneurs and civic action. The paper contributes to understanding how climate policy diffusion and norm domestication can have different political outcomes in achieving global climate goals and argues for increased policy attention to the strategic use of climate policy diffusion for the depoliticization of climate change. 相似文献

The Stern Review has played an enormous role in making the world of business aware of the challenge of long-term climate change. In order to make real progress on the basis of this awareness, it is important to pay attention to the difference between human suffering and losses of gross domestic product (GDP). The Review has compared climate change to experiences of suffering like World War I. That war, however, hardly affected global GDP. The long-term damages to be expected from business-as-usual greenhouse gas emissions include loss of the coastal cities of the world over the next millennia. This would be an act of unprecedented barbarism, regardless of whether it would slow down economic growth or perhaps even accelerate it. Business leaders worried about climate change need to pay attention to the tensions between ethical and economic concerns. Otherwise, a credibility crisis threatens global climate policy. An important step to establish the credibility needed for effective climate policy will be to gradually move towards a regime where emission permits are auctioned, not handed out as hidden subsidies. The revenues generated by permit auctions should be used to establish a global system of regional climate funds. 相似文献

This paper presents an assessment of the implications of climate change for global river flood risk. It is based on the estimation of flood frequency relationships at a grid resolution of 0.5?×?0.5°, using a global hydrological model with climate scenarios derived from 21 climate models, together with projections of future population. Four indicators of the flood hazard are calculated; change in the magnitude and return period of flood peaks, flood-prone population and cropland exposed to substantial change in flood frequency, and a generalised measure of regional flood risk based on combining frequency curves with generic flood damage functions. Under one climate model, emissions and socioeconomic scenario (HadCM3 and SRES A1b), in 2050 the current 100-year flood would occur at least twice as frequently across 40 % of the globe, approximately 450 million flood-prone people and 430 thousand km2 of flood-prone cropland would be exposed to a doubling of flood frequency, and global flood risk would increase by approximately 187 % over the risk in 2050 in the absence of climate change. There is strong regional variability (most adverse impacts would be in Asia), and considerable variability between climate models. In 2050, the range in increased exposure across 21 climate models under SRES A1b is 31–450 million people and 59 to 430 thousand km2 of cropland, and the change in risk varies between ?9 and +376 %. The paper presents impacts by region, and also presents relationships between change in global mean surface temperature and impacts on the global flood hazard. There are a number of caveats with the analysis; it is based on one global hydrological model only, the climate scenarios are constructed using pattern-scaling, and the precise impacts are sensitive to some of the assumptions in the definition and application. 相似文献

Climate change is putting Colombian agriculture under significant stress and, if no adaptation is made, the latter will be severely impacted during the next decades. Ramirez-Villegas et al. (2012) set out a government-led, top-down, techno-scientific proposal for a way forward by which Colombian agriculture could adapt to climate change. However, this proposal largely overlooks the root causes of vulnerability of Colombian agriculture, and of smallholders in particular. I discuss some of the hidden assumptions underpinning this proposal and of the arguments employed by Ramirez-Villegas et al., based on existing literature on Colombian agriculture and the wider scientific debate on adaptation to climate change. While technical measures may play an important role in the adaptation of Colombian agriculture to climate change, I question whether these actions alone truly represent priority issues, especially for smallholders. I suggest that by i) looking at vulnerability before adaptation, ii) contextualising climate change as one of multiple exposures, and iii) truly putting smallholders at the centre of adaptation, i.e. to learn about and with them, different and perhaps more urgent priorities for action can be identified. Ultimately, I argue that what is at stake is not only a list of adaptation measures but, more importantly, the scientific approach from which priorities for action are identified. In this respect, I propose that transformative rather than technical fix adaptation represents a better approach for Colombian agriculture and smallholders in particular, in the face of climate change. 相似文献

Public knowledge of global warming depends on the translation of climate science from specialist communities to citizens, and from scientific language to the vernacular; yet, no two cultures or languages being perfectly commensurable, this process of translation necessarily entails a transformation of the climate change concept. I explore this transformation, and the unexpected consequences it spells for local acceptance and understanding of climate science, through a case study in the Marshall Islands, a low-lying nation endangered by sea level rise and other climate change impacts. Various framings of this threat have been communicated to Marshall Islanders via local media, NGO, and government outlets. ‘Climate’ is here translated as Marshallese mejatoto, the closest equivalent in this Austronesian language. Yet mejatoto refers not only to climate/weather but also to the environment or cosmos in general, including the social sphere, a result of the Marshallese conceptual conflation of ‘nature’ and ‘culture.’ As a result, locals point to processes as disparate, and un-‘climatic,’ as a solar eclipse, accelerating time, and weakening tradition as examples of, and evidence for, climate change. In a society already vigorously possessed of narratives of change, this ‘promiscuous corroboration’ makes the prediction of climate change extremely easy to trust. While this ‘mistranslation’ carries with it certain dangers, when viewed instead as a reinterpretation it is rife with opportunity. Climate change communicators both abroad and at home must therefore carefully consider the transformations introduced by various translations of ‘climate change,’ yet also appreciate ‘mistranslation’ for its ability to render concepts meaningful to local actors and to stimulate citizen–scientist dialogue. 相似文献
