Linking permit markets multilaterally

We formally study the determinants, magnitude and distribution of efficiency gains generated in multilateral linkages between permit markets. We provide two novel decomposition results for these gains, characterize individual preferences over linking groups and show that our results are largely unaltered with strategic domestic emissions cap selection or when banking and borrowing are allowed. Using the Paris Agreement pledges and power sector emissions data of five countries which all use or considered using both emissions trading and linking, we quantify the efficiency gains. We find that the computed gains can be sizable and are split roughly equally between effort and risk sharing.     

The Impact of Global NGOs on Japanese Press Coverage of Climate Negotiations: An Analysis of the New “Background Media Strategy”

This article assesses the success of WWF Japan’s “Background Media Strategy” in influencing Japanese mainstream news outlets’ coverage of climate change negotiations. WWF Japan adopted this “Background Media Strategy” after the Bali COP in 2007; instead of lobbying, it aims to build journalists’ expertise. This article examines its success after seven years through three research approaches: the analysis of participant lists; two surveys (conducted in 2009 and 2015); and a content analysis of climate change articles that appeared in four large mainstream newspapers between April and July 2015. Based on these different data, the author concludes that the new media strategy was successful: Japanese journalists increasingly rely on information provided by WWF Japan and less on information provided by the government and industry. This experiment suggests that a new relationship between global NGOs and the media can improve environmental communications—an approach that could help advocacy groups around the world.     

Youth,climate change and visions of the future in Miami

ABSTRACT

Miami, FL, is one of the most climate-vulnerable cities in the United States. At an average elevation of only 6 feet above sea level, parts of the city could be made uninhabitable by rising oceans within the next 40 years. The effects of climate change are already beginning to be seen, but the subject of climate change is nevertheless modelled, imagined and contested in the future tense. Today's young people are similarly future oriented, but unlike older generations they will live to feel climate change's full future effects. This study investigates knowledge of and experiences with climate change among young adults in Miami, and their visions of the future in light of predicted changes. Semi-structured interviews were conducted with 19 long-term residents of the city between the ages of 18 and 30 who were students at Miami-Dade College or Florida International University. I discuss participants’ sense of personal responsibility to inform themselves and the individualised understandings of climate science that emerge, their disillusionment with politics and resulting perception of individual responsibility for climate mitigation, and their negotiation of personal future plans in light of fatalistic visions of the future. These young adults’ perspectives on rising seas in their home city are revealed to be socially structured by ideals of individual agency and self-reliance, which become paradoxically disempowering because of the impossibility of addressing the transformational impacts of climate change through individualised means.     

Does size matter? Comparing the party politics of climate change in Australia and Norway

ABSTRACT

The implications of state size for the party politics of climate change are examined, and in particular its effect in facilitating or impeding cross-party consensus on the issue. This issue is explored through an in-depth, qualitative comparison of Australia and Norway, which are shown to be comparable in important respects yet differ in terms of their size and climate politics. Original primary data is presented from 44 interviews with policymakers and policy-shapers in both countries, which shows that, to the limited extent that state size moderates the parties’ behaviour, it is the countries’ geographical – not economic – size that matters. Institutional factors are found to play a more significant role, however, and the corporatist features of state-business cooperation, strong ENGOs and compensatory welfare arrangements are highlighted as particularly important.     

Constructing regional scenarios for sustainable agriculture in European Russia and Ukraine for 2000 to 2070

This study estimates the consequences of climate change on cropland with and without implementation of adaptation measures, paying special attention to the maintenance of soil organic carbon (C) stocks. We examine the possibility for regional sustainable agricultural management practice that combines both maintenance and gain in soil carbon level with profit maximization. Future scenarios of Regional Agricultural Production Systems (RAPS) were constructed for 2000–2070 based on linking the effects of global climate change, predicted change in productivity parameters for the main agricultural crops, land-use and soil database parameters. The RAPS were used to examine profitability and feasibility of alternative agricultural scenarios, based on an economic model. A number of recommendations for decision making were proposed based on an assessment of the efficiency of adaptation in animal husbandry and in the crop production sector, after analysis of current percentage of perennial grass in rotation in comparison with future economic scenarios.

VISUALIZATION OF TRENDS AND FLUCTUATIONS IN CLIMATIC RECORDS1

ABSTRACT: Small systematic changes in climatic records are often poorly visualized by standard time series plots because they are usually hidden by the magnitude and variability of the data values themselves. A visualization approach based on the rescaled adjusted partial sums (RAPS) which overcomes the above-stated shortcomings is presented. This visualization highlights trends, shifts, data clustering, irregular fluctuations, and periodicities in the record. Additional information on the number, magnitude, shape, frequency, and timing of fluctuations and trends can also be inferred. The visualization approach can be used for preliminary visual inspection of a time series, to gain a feel for the data, and/or to guide and focus subsequent statistical tests and analyses. It is not intended as a substitute for standard statistical analysis. Alternatively, the visualization approach can be used to display findings of a time series analysis. The capabilities and limitations of the approach are discussed and illustrated for two time series of annual rainfall values.     

关于耕地总量动态平衡的思考

中国是一个人多地少的国家，伴随着80年代经济高速增长而加剧的人地矛盾已经成为区域可持续发展面临的一个重要问题。本文以大量的数据分析了自耕地总量动态平衡实施以来的1999-2001年耕地数量和质量的变化，其中用播面单产和复种指数来度量耕地质量，得出了我国总体耕地质量下降的结论，指出仅仅从数量上实施耕地总量动态平衡，保证不了我国粮食安全的需要。并在此基础上提出了相关的建议。     

有关全球气候变化问题上的公平性分析

从《联合国气候变化》了发，对人类社会应对气候变化中的“公平”性问题，从不同角度进行了系统讨论。对发展中国家和发达国家在公平原则下责任、义务及优先事项的差别进行了分析，提出并分析了以人均碳排放权相等为标准，到目标年（例2100年）各国人均碳排放量及过渡期内（例1990-2100）人均累积碳排放量两个趋同的碳排放权分配原则。     

气候变化和人类活动对历史时期黄河决溢的影响

本文统计分析了历史时期黄河决溢的变化。并从自然和人为因素两方面探讨其原因和规律。认为在湿润的气候时期黄河决溢频率增高,其原因是本地区高强度的暴雨造成了黄土高原严重的水土流失,从而使黄河中下游大量的泥沙沉积。人类特别是小冰期以来加强了对黄土高原的开发,破坏了原先的植被,从而造成了严重的水土流失,这是小冰期以来黄河决溢次数远远高于其它时期的主要原因。作者还认为在下世纪高温环境到来之际,黄河决溢的危险性大大增加。     

Equity Concerns over Climate Change Mitigation

As a complicated concept with ethical implications, equity or fairness in the field of climate change mitigation concerns the relations not only between individual human beings but also between human beings and the nature. In this paper, after the review of equity between individuals, market and non-market attributes of emissions rights are distinguished and discussed. Based on the argument of equal per capita emissions rights, three types of emissions rights and the concept of minimum emissions rights as social security are proposed.
