Tipping Points and Climate Change: Metaphor Between Science and the Media

Over the past decade, scientists and journalists have prominently utilized the metaphor of a tipping point for drastic, irreversible and dangerous climate change. This paper shows how the tipping point metaphor became a multi-purpose bridge between science and the news media, describing how its meaning and use developed and diversified in interaction between these two domains. Within the scientific domain, the metaphor developed from a rhetorical device conveying a warning of drastic, irreversible and dangerous climate change to a theoretical concept driving empirical research. The news media soon picked up the tipping point metaphor for abrupt and dangerous climate change, turning it into a common part of the journalistic lexicon. Moreover, both science and the news media developed another, societal use of the tipping point metaphor, calling for radical societal change to avoid climate change catastrophe. The tipping point metaphor is hence not a monolithic notion but a highly versatile concept and expression, allowing it to be used for various communicative purposes by distinct stakeholders in different contexts.     

Press Briefings in International Climate Change Negotiations

Press conferences are an important element of a government's communication strategy at climate change summits. From a theoretical perspective, press conferences should serve two main functions: exerting pressure in negotiations and informing the public. These functions correspond to two logics of action: a logic of consequence where governments use press conferences as negotiation tools and a logic of appropriateness where governments organize press conferences to increase transparency. Based on new data from the United Nations Framework Convention on Climate Change archives, we find limited support for these two logics of action. Neither democracies, which, we argue, are more likely to follow a logic of appropriateness, nor vulnerable countries, which are more likely to follow a logic of consequence, organize systematically more press conferences. Other factors, such as capacity and a government's function in the negotiation structure, seem to play a more important role.     

Mediating the Science: Symbolic and Structural Influences on Communicating Climate Change Through New Zealand's Television News

Climate change presents scientists, politicians, and media producers with a challenge of articulating to diverse stakeholders both the complexity of issues and the urgency of action. Analyses of how climate change is represented and constructed in broadcast media are useful to capture a reflection of contemporary values. We use an analysis of news frames and production values as well as a limited “circuit of culture” approach to explore climate change communication as both a news product and cultural phenomenon. Our focus is New Zealand, a country which ratified the Kyoto agreement but which is currently noncompliant. Using qualitative framing analysis and in-depth interviews with leading media producers, politicians, and scientists, we examine how climate change is produced, represented, and consumed by New Zealanders via their broadcast media.     

Meeting the Climate Change Challenge (MC3): The Role of the Internet in Climate Change Research Dissemination and Knowledge Mobilization

This paper explores the role that Internet and online technologies played in research dissemination and knowledge mobilization in a recent climate change research project, MC³. In addition, the team looked at the potential of online expert-practitioner research collaborations for these purposes. Electronic communication was seen as a key element for creating distributed networks essential to the project and for building new practitioner/research knowledge collaboratives. The paper discusses how online communication strategies and technologies were used for wide dissemination of its research outcomes. MC³'s research dissemination and knowledge mobilization strategies are analyzed, using engagement as the primary measure, to gain insights on the effectiveness and challenges of using Internet-based tools for communicating climate change innovations and actions.     

The Circulation of Climate Change Denial Online: Rhetorical and Networking Strategies on Facebook

This study uses a topical, rhetorical approach to analyze how climate change denial circulates online through the 25 most popular posts on the Watts Up With That and the Global Warming Policy Forum Facebook pages. These groups adopt the appearance of credibility through reposting and hyperlinking, thus establishing a supportive, networked space among other skeptical sites, while distancing readers from original sources of scientific information. Visitors use a variety of rhetorical strategies to echo posts’ main themes and to discredit alternative viewpoints. Differences between the topoi and rhetorical strategies of WUWT and the GWPF show that the climate change denial community is multifaceted and makes use of social media affordances to craft the appearance of legitimacy. This project contributes to our knowledge of how scientific information is co-opted, manipulated, and circulated in online spaces and how online features shape environmental discourse practices.     

Increasing Local Salience of Climate Change: The Un-tapped Impact of the Media-science Interface

ABSTRACT

The media play a vital role in framing the narrative on climate change, however little work exists to assess the extent to which local media outlets increase public engagement on climate change through interaction and engagement with local academics. As temperatures rise and concerns mount that we have passed the tipping point, local media play a potentially critical role in communicating how climate change exacerbates their impact. Based on a review of extant literature on this topic, and a small pilot email survey, this article argues that scientists could be more active in increasing local salience of climate change by building trusted relationships with local media. Coverage of science in the media could benefit from closer engagement with local scientists as environmental stories often get more coverage in local media (compared to national media) which constitute an important source of knowledge on climate change. This would enable constructive discussions between local media and scientists, better translation of science to publics, increased awareness and interest of science production locally, and ultimately creating a trusted intermediary in the science-public interface.     

YouTube,Social Norms and Perceived Salience of Climate Change in the American Mind

This online experiment explored how contextual information embedded in new media channels such as YouTube may serve as normative social cues to users. Specifically, we examined whether the number of views listed under a YouTube video about climate change would elicit inferences regarding how “others” feel about the climate issue and, consequently, might influence perceptions of issue salience. Participants in this experiment were exposed to a YouTube video about climate change using two experimental conditions, one providing a small number of views under the video and the second listing a large number of views. Results suggest that the “number of views” cue did, indeed, influence participant perceptions of the importance assigned by other Americans to the issue of climate change. Further, compared to low self-monitoring participants, high self-monitoring participants registered an increase in their own judgment of issue importance.     

Democratic Debate and Mediated Discourses on Climate Change: From Consensus to De/politicization

Starting from a risk conflicts perspective, this article challenges two common assumptions of existing research on climate change in public and media discourses. It argues that the evaluation of these discourses on the extent to which these either accurately reflect a scientific consensus or contribute to achieving social consensus insufficiently takes account of the exclusionary mechanisms it starts from. A conceptual and empirical framework is subsequently put forward which allows one to evaluate mediated discourses in terms of the extent to which democratic debate and citizenship are encouraged. Such analysis can reveal the discursive strategies underlying processes of politicization and depoliticization. This perspective is illustrated by an analysis of a local case study: the “Sing for the Climate” campaign. We conclude by calling for a broad systematic research agenda revealing the extent to which de/politicizing discourses are found to influence public and media discourses.

Unintended Effects of Emphasizing the Role of Climate Change in Recent Natural Disasters

In 2017, the United States experienced a series of natural hazards (hurricanes, wildfires, and blizzards) that resulted in significant loss of life and property. Emphasizing the role of climate change in these events might offer an important tool for engagement, particularly with skeptical audiences. However, in a survey experiment (N?=?1504) involving three different natural hazards – hurricanes, wildfires, and blizzards – we find that emphasizing the role of climate change in these hazards produced unintended effects for climate change skeptics. In particular, skeptics experienced resistance to the news article, which associated with reduced perceived hazard severity. These backfiring effects likely serve as a defensive mechanism used by skeptics to maintain their prior views of climate change, illustrating the challenges faced in communicating climate change to skeptical audiences. These findings offer additional insight for those attempting to communicate climate-related risk information to skeptical audiences.     

全球气候变化对中国森林影响的研究进展

通过梳理现有文献表明,全球气候变化对社会经济和自然生态系统造成了重大影响,气候变化将显著地改变森林生态服务的供给水平和质量,对森林和以林为生的人口都会造成重要的生态、经济和社会影响,甚至威胁到人类的生存.我国是受气候变化影响较大而适应能力较弱的发展中国家,森林适应气候变化的科学、社会经济及对策研究相对滞后,因此,笔者从气候变化对历史上森林生态系统的影响着手,阐述了气候变化对森林分布、森林演替、森林生产力、生物多样性、森林火灾、森林水文调节和水质、森林生态系统的未来、森林生态服务的水平和质量等方面产生的影响,分析了现有气候变化对森林影响的研究存在的不足:忽略了其它环境因子的作用;忽略了不同物种之间的竞争机制;缺乏对极端气候事件的考虑;缺乏森林自身变化对气候变化的反馈;缺乏森林生态系统对全球气候变化相应机制更深入的认识;研究模型及数据的不完善性.文章最后提出了可将气候变化对森林造成的危害降到最低限度的政策建议.     

Media Representations of Climate Change: A Meta-Analysis of the Research Field

A flurry of studies in recent years has analyzed the role of media in climate change communication. This article provides a systematic, large-scale, and up-to-date overview of the objects and characteristics of this research field through a meta-analysis. It identifies 133 relevant studies and analyzes them empirically. The results show that research activity has risen strongly over time, and that the analytical spectrum has expanded to include an increasing number of countries, more types of media including online and social media, and different methodological approaches. The analysis also demonstrates, however, that scholarship in the field still concentrates strongly on Western countries and print media.     

Developments in the Framing of Climate Change as a Public Health Issue in US Newspapers

News media are major channels for the transmission of information to the public and deliver news about the latest developments regarding health issues such as climate change. How the media frame such information may enhance public understanding and enable appropriate responses by individuals and communities. This study follows up on previous research examining media portrayals of climate change in US newspapers from 1 January 2007 to 31 December 2008. Here, we content analyze 270 news stories on climate change as a public health issue from five US newspapers between 1 January 2011 and 31 December 2012. Findings indicate that the total number of articles about climate change declined while emphasis on the public health dimension of climate change increased. The types of generic news frames (i.e., dramatic/substantive) most frequently used did not considerably change across the two time periods, however. To explain this, we discuss ways in which people may assess and spark change in news framing of public issues to better reach and influence a range of audiences.     

Media and Climate Change: Four Long-standing Research Challenges Revisited

This paper suggests some further avenues of empirical and theoretical investigation for media research on climate change. “Old” suggestions, whose significance, as we see it, needs to be further reinforced, are included, as are “new” ones, which we hope will generate innovative research questions. In order to integrate the analysis with knowledge generated by media research at large, we revisit four research challenges that media scholars have long grappled with in the investigation of journalism: (1) the discursive challenge, i.e. the production, content and reception of media discourse; (2) the interdisciplinary challenge, i.e. how media research might engage in productive collaboration with other disciplines; (3) the international challenge, i.e. how to achieve a more diverse and complex understanding of news reporting globally; and (4) the practical challenge, i.e. how to reduce the theory–practice divide in media research.     

Metaphors in Guardian Online and Mail Online Opinion-page Content on Climate Change: War,Religion, and Politics

In climate change-related media discourses metaphors are used to (re-)conceptualize climate change science as well as climate change mitigation/adaptation efforts. Using critical metaphor analysis, we study linguistic and conceptual metaphors in opinion-page content from the British online newspapers Guardian Online and Mail Online, while paying attention to the arguments they advance. We find that Guardian Online employed war metaphors to advance pro-climate change arguments. War metaphors were used to (1) communicate the urgency to act on climate change and (2) conceptualize climate change politics. Mail Online employed religion metaphors to furnish skeptic/contrarian arguments. Religion metaphors were used to (1) downplay the urgency to act on climate change and (2) conceptualize transitions from climate change belief to skepticism. These findings raise concerns about sustained policy gridlock and refute expectations about novelty in climate change-related media discourses (as both war and religion have a history of use).     

Climate Change and Energy Technologies in Undergraduate Introductory Science Textbooks

Global climate change and the implementation of energy technologies are among the most pressing issues facing society and the environment today. Related educational content spans the science disciplines. Through an analysis of introductory-level university textbooks from four major US publishers in Biology, Chemistry, and Physics, this study presents trends in terminology and content. As the defining terms, “global warming” and “climate change” are used nearly equally. However, the first location of a working definition for climate change appears earlier. Energy technologies, climate change, and related environmental issues are found, on average, on ≤4% of textbook pages, and variation is large among individual textbooks. Discipline-based trends exist, especially for the energy technologies presented. Addressed separately as a non-renewable, non-fossil fuel, nuclear energy is found on ≤1% of textbook pages and unfavorably represented. The discussion within these science disciplines has implications on introductory-level education, public perception of science, and informed citizenship.     

中国在气候变化谈判资金机制演变进程中的挑战及应对

气候变化是当今人类社会面临的最严峻的全球性环境挑战之一,气候变化谈判关乎各国在气候秩序中的权力与义务,涉及到各国经济发展的根本利益,已经成为国际政治博弈的新舞台.根据联合国气候变化框架公约和巴厘路线图精神,发达国家应承担起历史责任,向发展中国家提供新的、额外的、可持续的、可预测的资金支持,帮助其应对气候变化的不利影响.但是,由于发达国家缺乏履行公约义务的政治诚意,长期以来在资金问题上同发展中国家展开了艰苦的斗争.哥本哈根会议后,全球应对气候变化资金呈现出资金来源多样化,资金规模逐渐缩水,资金治理机制对发达国家出资约束力近一步降低的趋势.各利益集团围绕资金机制谈判展开激烈博弈,欧盟与美国正在逐步突破“共同但有区别的责任”原则,争夺气候变化谈判领导权并力图将我国拉入出资国之列,发展中国家阵营逐步分化为“基础四国”、“小岛屿国家”、“最不发达国家”等,保持共同立场难度日渐增大.尽管绿色气候基金在德班会议后正式启动,若无资金注入,也只能为未来资金机制谈判带来不确定性.面对上述形势,我国应坚持公约基本原则,坚持发展中国家定位,加强综合研究及前瞻性判断,以积极的姿态和务实的态度参与应对气候变化的国际谈判,以争取自身的发展权益,维护国家核心利益.同时,探索在当前发展阶段下发展低碳经济和建立低碳社会的路线图,不断提高减缓和适应气候变化的能力,实现自觉减排,为全球应对气候变化做出积极贡献.     

Researching Visual Representations of Climate Change

This paper responds to calls for greater clarity about the application of theory and method in research on mediated communication about climate-change. Specifically, it identifies conceptual and methodological challenges for researching visual representations of climate change. We suggest current research is impeded by a lack of methodological explication and an unclear relationship between theories of visual meaning and the application of social science methods such as content analysis and frame analysis. As a first step towards addressing these issues, we review existing research to identify the methodological procedures that require explication in order to support the replication of studies and the comparison of findings. We then draw on the seminal work of Roland Barthes to examine how theories of visual meaning may be integrated into social-scientific research methods. Specifically, we demonstrate how Barthes’ concepts of denotation, connotation and mythology may be related to research concerns about the selection of visual content, the classification of image frames, audience responses, and analyses of ideological meaning. The conclusion highlights further possibilities for developing a robust form of visual analysis that meets the standards of social scientific research while addressing the fundamental insights about visual meaning derived from cultural theories of meaning.     

Structure and Content of the Discourse on Climate Change in the Blogosphere: The Big Picture

Based on the texts of 1.3 million blog posts and the structure of the links between the blogs in which these posts appeared, this study presents an analysis of the discourse on climate change in the English-language blogosphere. Our approach combines community detection with probabilistic topic modeling to show how topics related to climate change are discussed across various parts of the blogosphere. We find that there is one community of predominantly climate skeptical blogs but several accepter communities. The topic analysis reveals a series of issues that are characteristic of the climate change discourse in the blogosphere. Two topics, one related to climate change science and one related to climate change politics, are particularly important for characterizing the discourse. We also find that the distribution of topics over the communities cuts across the divide between skeptics and non-skeptics (accepters) and that there are differences in the patterns of interactions between the skeptics and different groups of accepters.     

中国适应气候变化技术分类研究

近百年来,全球气候变化呈现出变暖的主要特征,气候变化所带来的影响日趋严重,其所造成的经济损失在全球范围内显著上升。适应气候变化是现阶段应对气候变化行动的重要方面,适应气候变化的技术分类研究是清晰认识适应气候变化的基础,是实现适应技术集成并构建合理有效的适应技术体系的手段。本文通过对适应气候变化技术分类问题的分析,提出了不同的适应气候变化技术分类方式,气候变化影响过程、区域、领域、适应目的、适应机制、适应时效、适应程度、适应层面等,针对气候变化及其影响梳理了中国不同区域与不同领域的适应气候变化技术清单。从气候变化影响过程来看,可以将适应气候变化技术分为气候变化影响发生前、发生过程中、发生后三类;从区域与领域气候变化影响来看,可以将适应气候变化技术分为八大区域与七大领域;本研究重点针对八大区域与农业、水资源、生态环境三大领域进行了分析。通过研究发现,现阶段适应气候变化技术分类研究尚存在一些问题,适应气候变化技术分类的导向不明确,造成对适应技术认识的不清晰;适应气候变化技术的分类往往与分层混淆在一起,导致人们对适应气候变化技术的认识和理解出现偏差;适应气候变化技术分类对适应行动的指导作用存在不足。综合来看,对适应气候变化技术进行精细分类,可以为适应气候变化技术的筛选、集成、效益评估奠定基础,推进适应气候变化行动高效有序开展,为适应气候变化技术体系构建提供支撑。
