长三角地区能源消费与区域发展相互关系及其影响因素

以长三角地区上海、江苏和浙江3省市为研究对象,运用Johansen协整检验、向量误差修正模型（VEC）和Granger因果检验等方法分析能源消费与经济发展的相互关系,并利用LMDI方法对3省市1995~2007年的能源强度进行分解分析,得到能源消费与区域发展关系的影响因素。结果表明：近年来长三角能源消费形势严峻,并较多地受到产业结构调整的影响。上海和江苏的能源消费在一定程度上拉动了经济发展,但是随着产业结构的调整,上海工业结构的调整促进了能源强度降低,而江苏却正好相反。近年来,浙江省的经济发展对能源消费的影响比较显著,随着该省工业规模扩大,能源强度有所升高,但是其产业结构的调整有利于降低能源强度。     

Global Journalism in Decision-Making Moments: A Case Study of Canadian and American Television Coverage of the 2009 United Nations Framework Convention on Climate Change in Copenhagen

Climate change is a phenomenon with global causes but local effects, and thus global climate change decision-making moments provide ideal opportunities to examine how local and global discourses work together—or do not—through global journalism. This case study investigates the globally focused vs. culturally bound frames used in television news coverage, in Canada and the USA, of the 2009 United Nations Climate Change Conference in Copenhagen. Initial quantitative findings that Canadian media used many more culturally bound sources than did American media contradict the past findings and suggest Canadian media engaged less in producing global journalism than did American media. A follow-up qualitative analysis not only found more global framing in the American stories, but also concluded that global sources did not necessarily create global journalism; instead, a global orientation is required.     

Developing sustainable practices to adapt to the impacts of climate change: a case study of agricultural systems in eastern England (UK)

The weight of scientific evidence suggests that human activities are noticeably influencing the world's climate. However, the effects of global climate change will be unevenly spread, due to local variations in vulnerability and adaptive capacity. Using downscaled projections of future UK climates over the next 50 years, this paper investigates the impacts of, and possible responses to, climate change in one small area in eastern England, selected as a test-bed for sustainable agriculture. It shows that local agricultural systems are vulnerable to changes in the climate. At present, however, these considerations have a limited effect on agricultural operations, which are mainly driven by short-term events and 'non-climate' policies, such as agricultural price support. The capacity of agricultural systems to adapt successfully to climate change will be determined by the ability of producers to integrate climate change into their planning strategies with a view to ultimately ensuring sustainable agricultural practices in the long term.

Using Expert and Non-expert Models of Climate Change to Enhance Communication

Climate change is a significant global risk that is predicted to be particularly devastating to coastal communities. Climate change adaptation and mitigation have been hindered by many factors, including psychological barriers, ineffective outreach and communication, and knowledge gaps. This qualitative study compares an expert model of climate change risks to county administrators' “mental” models of climate change and related coastal environmental hazards in Crystal River, Florida, USA. There were 24 common nodes in the expert and the combined non-expert models, mainly related to hurricanes, property damage, and economic concerns. Seven nodes mentioned by non-experts fit within, but were not a part of, the expert model, primarily related to ecological concerns about water quality. The findings suggest that effective climate outreach and communication could focus on compatible parts of the models and incorporate local concerns to find less controversial ways to discuss climate-related hazards.     

气候变化对白洋淀湿地的影响

生态系统对气候变化的影响和响应的敏感性研究是全球变化研究的一个重要内容。近年来,华北地区气候以暖干为主,这种趋势在一定程度上加剧了华北地区的水危机。特定的水文条件是湿地形成与维持的驱动因子,因此湿地生态系统对气候变化尤为敏感。以华北地区内陆湖泊白洋淀为研究对象,通过分析白洋淀过去40年气候、水文与生态系统发展变化过程及湿地生态与影响因子之间的相关关系,确定湿地退化的主导生态因子,探寻湿地退化的驱动机制。从而得出以下结论：1960年以来,白洋淀湿地水位降低,水量减少,面积萎缩,干淀频繁,生物多样性减少;气候变化在白洋淀湿地退化中起决定作用,其中降水对湿地的影响最大。气候变化主要通过改变湿地的水文特征,减少湿地水源补给,增加水分消耗,使湿地退化萎缩。人为因素在一定程度上加剧了这种趋势。     

Matching mechanism in global public goods games: a case of climate protection

In the setting of dealing with climate change, this article designs a matching mechanism for global public goods provision with the aggregative game approach. Given endowment and the technology of each country, we propose the conditions under which the matching mechanism is able to guarantee full participation and Pareto efficient provision, respectively, in the cases with certain and uncertain preference information. These conditions cannot only be adopted in international negotiation and cooperation, but also refines the theory of matching game. In comparative static analyses, we discover that: First, changes of initial stock of climate goods produce a wealth effect and the crowd-out effect is less than 1. Second, climate tax policies affect the supply and welfare of each country only when they produce wealth effects, and if tax revenue is transferred into climate goods with more advanced technology, they will produce positive wealth effects. Third, modifying matching plans dynamically and appropriately can urge countries to improve technology, and especially given a Pareto optimal mechanism, adjusting the matching plan to keep marginal rates of transformation unchanged as technology changes is still able to ensure full participation and efficient supply of climate goods.     

Portraying the Perils to Polar Bears: The Role of Empathic and Objective Perspective-taking Toward Animals in Climate Change Communication

Images of animals, particularly polar bears, harmed by climate change are often used in environmental campaigns, despite warnings of potential reactance and resultant perceived distance from the issue. As an alternative to these emotional appeals, environmental campaigns could encourage an objective (i.e., emotionally detached) perspective on climate change impacts. The present research tests the effects of a message that encourage empathic vs. objective perspectives toward polar bears harmed by climate change on emotions and subsequent support for climate change activism among 241 American adults through an online survey. Contrary to popular warnings, the present research found no reactance toward portraying harm to polar bears from climate change and no benefits of taking an objective perspective toward the polar bears. Instead, portrayals of polar bears harmed by climate change motivated both environmentalists and non-environmentalists to donate money to environmental activist groups when they took an empathic perspective toward the animals. Empathy and hope explain effects for environmentalists and empathy, hope, worry, personal guilt, and boredom explain effects for non-environmentalists.     

Climate capacity:the measurement for adaptation to climate change

This article proposed the concept of"climate capacity"as a way of measuring human’s adaptiveness to climate change.This article also focused on the related concepts like ecological carrying capacity,water resources carrying capacity,land carrying capacity as well as population carrying capacity.The concept of climate capacity was articulated against a background of global climate and environmental change.Essentially,China’s efforts to adapt to climate change was a matter of improving climate capacity,which is the ecosystem as well as the frequency,the intensity and the scale of human’s social activities that the climatic resources of a particular geographic area were supposed to support.The climate capacity has two components.One is the natural climate capacity,which includes temperature,sunlight,precipitation,extreme climatic events,etc.The other is the derived climate capacity,which includes water resources,land resources,ecological systems,climatic risks,etc.The climate capacity can be developed or be transferred between regions by taking engineering,technology or regime-based adaptive measures.However,these adaptive measures must be implemented under the principle of economic rationalism,ecological integrity,climate protection,and social justice.It is expected that by combining the climate capacity and its threshold value with the assessment of climate change risks,we are able to predict the optimal population carrying capacity and the scale of socioeconomic development,and furthermore,provide policy support for the socioeconomic development strategy and adaptive planning.In the regions with high climate capacity,there is a symbiotic relationship between adaptation and socioeconomic development.But,in the regions with limited climate capacity,irrational development may further damage the environment.Taking the Yangtze River delta,a region with high climate capacity,and a region of Ningxia,a region with limited climate capacity,as illustrative examples,the authors of this article analyzed the policy implications of climate capacity and further made suggestions on the problems of capacitylimited adaptation and development-driven adaptation.This article argued that the concept of climate capacity can not only be used as an analytical instrument of climate change economics,but also it can provide research support for planning regional adaptation and development with climate change impact and risk assessments.     

Canadian Weathercasters’ Current and Potential Role as Climate Change Communicators

ABSTRACT

Climatologists worldwide are calling for urgent action to manage climate change, but public engagement remains a significant challenge. This lack of engagement is often attributed to psychological distance: climate change is perceived as something happening far away, to other people, or in a hypothetical future. TV weathercasters are ideally situated to communicate the geographically and temporally proximate impacts of climate change and increase public engagement. This study explores the status of climate change reporting amongst weathercasters in Canada, where no such research has been conducted. The respondents suggested that many, but not all, weathercasters are engaged with climate change and interested in presenting local, climate-related content; however, their on-air climate change communication behavior is highly limited. This analysis builds on research conducted with American weather broadcaster by indicating that Canadian weathercasters share their potential as effective climate change communicators, but are highly uncertain about their capacity to support this role.     

Cognition Research on Global Climate Change

Researchers are looking for an effective solution to mitigate climate change along with the growth of global average temperature and the frequent occurrence of extreme climate disasters. However, after the ratification of Kyoto Protocol, which is the international agreement dedicated to solve the problem, climate change is getting more serious in the recent decade. It is considered that the ultimate reason is not from the limitation of current technology or policy instrument but from the cognition part, which is the basis guiding people to comprehend problems and search for solutions. Until now, the research on the climate change issue is consistently based on a deficient assumption that climate change is a kind of “the tragedy of the commons.” This phenomenon could be considered as the “Pluto phenomenon” and directly cause the inefficiency of current solution. Therefore, the cognition's reconstruction is vital to guide researchers and relevant stakeholders to search for an efficient approach to mitigate climate change.     

Assessing coastal vulnerability to climate change: comparing segmentation at global and regional scales

Recent concerns about potential climate-change effects on coastal systems require the application of vulnerability assessment tools in order to define suitable adaptation strategies and improve coastal zone management effectiveness. In fact, while various research efforts were devoted to evaluate coastal vulnerability to climate change on a national to global level, fewer applications were carried out so far to develop more comprehensive and site-specific vulnerability assessments suitable to plan possible adaptation measures at the regional scale. In this respect, specific indicators are needed to address climate-change-related issues for coastal zones and to identify vulnerable areas at the regional level. Two sets of coastal vulnerability indicators were selected, one for regional and one for global studies, respectively, concerning the same features of coastal systems, including topography and slope, geomorphological characteristics, presence and distribution of wetlands and vegetation cover, density of coastal population and number of coastal inhabitants. The proposed set of indicators for the regional scale was chosen taking into account the availability of environmental and territorial data for the whole coastal area of the Veneto region and was based on site-specific datasets characterized by a spatial resolution appropriate for a regional analysis. Moreover, a GIS-based segmentation procedure was applied to divide the coastline into linear segments, homogeneous in terms of vulnerability to climate change and sea-level rise at the regional scale. This approach allowed to divide the Veneto shoreline into 140 segments with an average length of about 1 km, while the global scale approach identified four coastal segments with an average length of about 66 km. The performed comparison indicated how the more detailed approach adopted at the regional scale is essential to understand and manage the complexities of the specific study area. In fact, the 25-m DEM employed at the regional scale provided a more accurate differentiation of the coastal area's elevation and thus of coastal susceptibility to the inundation risks, compared to the 1-km DEM used at the global level. Moreover, at the regional level the use of a 1:20,000 geomorphological map allowed to differentiate the unique landform class detected at the global level (e.g., fluvial plain) in a variety of more detailed coastal typologies (e.g., open coast eroding sandy shores backed by bedrock) characterized by a different sensitivity to climate change and sea-level rise. Accordingly, the information provided by regional indicators can support decision-makers in improving the management of coastal resources by considering the potential impacts of climate change and in the definition of appropriate actions to reduce inundation risks, to avoid the potential loss of valuable wetlands and vegetation and to plan the nourishment of sandy beaches subject to erosion processes.     

Communicating Local Climate Risks Online Through an Interactive Data Visualization

Literature suggests a need to develop climate communication tools that focus on the impacts of climate change at local scales to increase proximity and communicate the risks on a more personal level. However, the nature of raw climate projection data makes accessibility by the lay audience a challenge and necessitates the need for innovative technological approaches to its distribution. ClimateData.US was created as an interactive visualization tool based on downscaled climate projection data to increase proximity and render climate change as salient and personally relevant. This experiment evaluated whether interacting with ClimateData.US influenced participants’ climate change attitudes and concern and whether this effect varied as a function of geographic proximity. Findings revealed strong effects—regardless of geographic proximity—for interacting with the website on participants’ perceived reality of climate change, attitude certainty, and concern for climate change.

Impacts of climate change in rapidly urbanizing region – a case study in Hangzhou (China)

Climate change is expected to be a major driving force of landscape in the coming decades. It will have a multitude of potential impacts that vary in intensity and effect according to region and sector. In the context of global warming, the climate of China has changed significantly in the recent 100 years. The reason for climate change in China is mainly due to irrational land use caused by human activities, which chiefly results in the rapid industrialization and urbanization process. Based on an assessment model, this research represents a picture of the impacts of climate change in six districts of Hangzhou region. The aim of this paper is to conclude, on the one hand, some of Hangzhou sensitivities in relation to the primary effects of climate change. On the other hand, a reflection is made on a methodology to formulate preconditions on a scientific basis for further research by design of integrated adaptation options for the future spatial developments in function to upgrade Hangzhou resilience in relation to climate change challenges.     

Elites, climate change and agency in a developing society: the Chilean case

Faced with global climate change, local elites are confronted with the main dilemma of a developing country: development requires economic growth, but this effort also requires consideration of environmental factors and sustainable patterns of production and consumption. Based on empirical evidence from qualitative research on businesses and political elites in Chile—a paradigmatic South American middle-income country—this paper explores the extent to which local elites are aware of the severity of challenges posed by global climate change and identify main climate change concerns in their discourse. The degree to which domestic elites are aware of the paradigm shift they must assume toward clean industrial production is a key issue of environmental governance that involves private non-governmental actors. This paper gives clues to a better understanding of what is happening with strategic actors in developing nations and their understanding of their decision-making capacity concerning environmental policy and investments for facing global climate change. The main conclusion of the research is that awareness of climate change in local elites’ discourse is relative. It is not accompanied by a full acceptance of their agency and is not leading to a paradigm shift toward a clean model of development because of domestic elites’ position within globalization processes.     

应对气候变化需以生态文明理念构建全球技术合作体系

气候变化是人类发展过程中遇到的最大全球性环境问题,也是最大的外部性问题。IPCC报告显示,实现本世纪末温度升高不超过2度的目标,需要全球经济和能源系统深度的低碳转型,并在本世纪下半叶达到温室气体的净零排放。应对气候变化因此面临着前所未有的技术创新与合作需求。2015年底达成的《巴黎协定》提出了落实技术开发与转让的长期愿景,主张对气候变化领域的技术创新给予政策和资金支持,使发展中国家在技术周期的早期阶段就能够获取必要的技术,从而为实现全球应对气候变化提供保障。然而,基于工业文明的传统技术创新与合作模式难以满足保护全球气候的技术需求。减缓与适应技术是气候变化挑战下全球命运共同体的公共财富。为保证其足够的供应,必须超越追求私人利益最大化的狭隘,基于生态文明理念构建全球应对气候变化的新型技术合作体系。其核心是:实现多赢的合作目标,遵循"生态人"的合作原则,体现协同的合作内容,基于互信的合作形式,鼓励多元主体的参与,促进合作成果的分享。中国作为新兴发展中大国,对应对气候变化技术国际合作有多元的利益需求。为有效落实《巴黎协定》,亟需以加速国际合作为契机,积极谋划中国应对气候变化技术对外合作的总体方略和具体行动,有针对性地制定与发达国家、其他发展中国家及欠发达国家间优势互补的合作计划,探索并引导"南-北-南"三方技术合作等新形式。     

气候变化研究的中国知识贡献及其影响局限

气候变化知识的不断深化和积累是全球气候治理的基础。政府间气候变化专门委员会(IPCC)邀请全球有代表性的科学家,通过分析评估国际上正式发表的文献,提供关于全球气候变化科学进展的最新认识结论。本文基于文献计量学,通过统计中国在气候变化十大重要领域的科技成果产出量和影响力、中国政府和科学家对IPCC评估报告的参与以及中国大陆引文在IPCC第五次评估报告中的贡献,分析了中国对全球气候变化知识的贡献与局限。结果表明:近十年来,中国在气候变化大多数领域的科技成果产出量已居全球第二或第三位,但在海洋与气候变化、适应气候变化和全球气候治理领域的国际论文量明显落后;与美国和英国相比,中国气候变化科技成果的各类影响力指标明显偏低;中国对IPCC评估报告的参与度和影响力在不断提升,中国积极组织相关机构和专家参与IPCC评估工作,对全球气候治理起到了重要的科学支撑作用;但从IPCC第五次评估报告中国大陆引文的角度看,中国贡献仍整体偏弱,中国大陆引文的贡献呈领域分布不均衡,优势领域少,成果影响面窄的特点。与科学基础领域相比,中国在影响和适应、减缓和国际合作领域的科学贡献更弱,对全球视角关注不够,但中国大陆引文总体的国际科学合作活跃度较高。后巴黎时代,中国需要更加面向国家需求、气候公约和《巴黎协定》目标以及国际气候变化科技前沿,加强全球视野和原始创新,突出中国优势和特色,使气候变化的中国研究成果更多支撑全球气候治理进程的推进。

Assessing National Discourse and Local Governance Framing of Climate Change for Adaptation in the United Kingdom

While many national governments struggle to maintain global climate change as a high priority issue, many local governments are taking action to fill the policy gaps. This study examines how local governments across the United Kingdom of Great Britain are reframing climate change. We compiled a dataset of newspaper publications covering climate change over a 10-year timeframe, plus survey and interview responses from local governance practitioners, to identify a shift in national discourse that has changed the priority level of climate change in UK local governance. This paper argues that many local governments are strategically reframing climate change as alternative issues in order to make progress in climate adaptation planning.     

Constructions of Climate Change on the Radio and in Nepalese Lay Focus Groups

To date analyses of media climate change constructions have mostly focused on coverage in western newspapers. Consideration of coverage in developing countries, and analyses of media constructions alongside local understandings of climate change are comparatively rare. This article provides an analysis of the construction of climate change on Nepalese radio and lay constructions of environment and climate change within the country. Data from a radio program and six focus groups are analyzed. Analysis of the radio program indicated that climate change was portrayed as a certain reality with national impacts caused by the actions of the West. While climate change dominated the radio headlines, in focus groups local environmental problems received far more attention. The paper aims to both inform directions for future climate change communication in Nepal and the wider research agenda.
