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.     

Pros and cons of climate change in China

Climate change strongly affected the structure and functions of natural ecosystems,e.g.the vegetation productivity decreased in the Northeast permafrost region due to the higher temperature and less precipitation,whereas in the Tibetan Plateau,the vegetation productivity increased,owing to the improved thermal resource.Climate change led to reduced precipitation in North and Northeast China and thus the reduced surface runoff.The public needs for energy were changed because of climate change,e.g.the shorter heating period in winter.Climate change profoundly influenced human health,pathophoresis and major projects by increasing extreme events,including frequency and magnitude,and causing more serious water shortage.Under the background of climate change,although the improved thermal resources can be helpful for extending the crop growth period,more extreme events may resulted in more instability in agricultural productivity.Not only did climate change indirectly affect the secondary and tertiary industries through the impacts on agriculture and natural resources,but also climate change mitigation measures,such as carbon tax,tariff and trading,had extensive and profound influences on the socioeconomic system.Further analysis indicated that the impact of climate change presented significant regional differences.The impact had its pros and cons,while the advantages outweighed the disadvantages.Based on the above analysis on the impacts of climate change,we put forward suggestions on coping with climate change.First,scientifically dealing with climate change will need to seek advantages while avoiding the disadvantages of climate change in order to achieve the orderly adaptation to climate change,which is characterized with"Overall best,long-term benefit."Second,quantitative adaptation should be given more attention,e.g.proposing operational schemes and predictable goals and using uncertainty analysis on adaptation measures.Third,more active coping strategy should be adopted to enhance China's future comprehensive competitiveness.The strategies include but are not limited to gradually adjusting the industrial structure,intensifying the research and development(RD)of emission reduction technology and actively responding to the influence of carbon tax,tariff and trading on socioeconomic development in China.

国际气候变化科学和评估对中国应对气候变化的启示

科学研究和评估工作推动了国际应对气候变化进程,并加大了各国行动力度。更多的科学证据表明人类活动是造成全球气候变暖的主要原因;气候变化影响、适应和脆弱性研究范围不断扩展和深化,区域甚至次国家级层面的问题受到高度关注;2℃温控目标的实现已然成为共识,政策协调与集成及相关政策在不同领域的协同作用成为研究的热点。未来中国应对气候变化需要在四个方面进一步开展研究和采取行动:1加强不同学科和领域的研究工作,围绕与实现温升控制1.5℃、土地利用、海洋以及城市相关问题开展专题研究。2加强国内绿色低碳转型和国际谈判的战略研究。3构建气候服务体系,以灾害风险管理为抓手,提升气候变化适应水平。4通过构建能源互联网实现能源变革,加快推进国内能源革命和经济发展的低碳转型。     

“十二五”以来中国应对气候变化政策和行动评述

基于广泛系统的文献梳理和总结,凝练了“十二五”以来中国应对气候变化政策和行动的现状、特点及成效,并提出针对性建议。主要结论包括:从外部环境看,国际形势对中国应对气候变化事业的推动作用呈现递减态势,之前“以外促内”的国内气候治理特点逐步转化为“内生动力为主”和“内外协调”;从政策制定和执行模式看,“集思广益”“上书模式”持续,“上下互动”“智库支持”的政策学习特点更加明显;从政策体系上看,已经形成相对成熟的符合中国国情的完整体系,推动气候治理能力显著提高;从政策总体特点看,呈现规划主导并引领、行政手段先行市场机制跟进、由点到面有序扩展、环境与气候协同治理、中央和地方互动博弈形成动态平衡、短期内政策成本较高等特点。“十二五”至今,中国应对气候变化政策行动效果明显,提前实现了2020年应对气候变化目标,并在污染治理、经济发展等方面产生广泛协同效应。“十三五”中期以来,中国应对气候变化组织管理机构进行了重大调整,从中央到地方气候政策和行动进入调整阶段。同时,更加强调气候政策和环境政策的协同。展望未来,中国应对气候变化政策和行动应该尽快走出调整期,充分利用新体制的优势,以碳总量控制目标为抓手,坚定推动以全国碳排放权交易为中心、多措互补的政策体系,注重适应行动以应对不断放大的气候风险,继续提高公众对应对气候变化政策的认知度、接受度和参与度,并不断加强技术研发和储备。     

“十二五”以来中国应对气候变化的行政手段评估

在中国应对气候变化政策体系中,目标责任制和淘汰落后产能这两项行政手段具有核心地位。充分认识其作用机制,阐述其优势与不足,对于中国碳减排政策的优化设计意义深远。本文遵循气候变化评估报告的原则和方法,以国内外公开发表的相关文献为基础,评估了这两项政策的作用机制、政策有效性以及存在的问题。结果显示:目标责任制和淘汰落后产能这两项行政手段具有高度的有效性。这些行政手段顺应了中国的各项体制机制,确保了中国应对气候变化目标的实现。具体来看,节能降碳目标责任制通过明确地方政府作为节能降碳政策执行主体的责任,改变了原有的官员激励体系,强化了政府对既有政策的执行,还促进了地方政府和企业各项节能降碳制度的形成。淘汰落后产能以目标责任考核为基础,结合各种激励政策,在节能降碳、化解产能过剩等方面发挥了巨大效应。尽管行政手段在温室气体减排中的作用非常有效,但是这种自上而下的压力传递机制难以真正内化为地方政府和企业开展节能降碳工作的自发性力量。此外,由于节能降碳目标的层层分解,县级及以下政府承担了与其行政管理权限并不匹配的责任。在压力体制下,过剩产能的市场退出障碍和地方政府、企业产能扩张的冲动依然存在。未来应结合行政和市场手段的优缺点,综合施策,促进温室气体减排长效机制的形成。     

International mechanism for loss and damage from climate change: recommendations for related work in China

Loss and damage (L&D) from climate change has threatened the sustainable development of humankind, while the progress of mitigative and adaptive measures carried out under the international multilateral framework has been slow. The scientific community and policymakers have placed increasing emphasis on the international L&D response mechanism as a potential direct solution. This paper reviewed the origins of such a mechanism, with an in-depth analysis of the related connotations. A review of the existing situation in China on work related to L&D arising from climate change was conducted, followed by a summary of the findings. Finally, measures and recommendations to improve China’s efforts were proposed in this issue.     

Resources and international climate change policy gridlock

Few other policy zones are as complex as the issue of climate change. If the more pessimistic projections of climate change doom are correct, then the failure to address the issue is likely to be catastrophic and irreversible. The Inter-governmental Panel on Climate Change has predicted the potential extinction of many species and that the existence of small-island and other vulnerable countries will be threatened if business-as-usual greenhouse gas emissions continue. Climate change is a transboundary problem and requires unprecedented levels of cooperation between states and serious and sustained responses from major emitters. However, the growing demand and consumption of natural resources for continued energy security and cornucopian economic growth have undermined the outcomes of international climate change negotiations. It is argued here that there is a strong connection between the major emitters’ positions at United Nations’ climate talks, their possessions, dependence and consumption of natural resources, and the continued undermining of international climate change policy for unsustainable growth. This paper assesses the resource politics of the US, China, India, Canada, Russia, and Saudi Arabia and their positions at climate talks to show the link between lack of climate change policy progress and the positions of these main players.     

Climate change adaptation approaches with nomadic culture characteristics in Inner Mongolia grassland in China

Climate change adaptation is an important part of addressing climate warming. Inner Mongolia grassland is a sensitive and vulnerable area of climate and an important region for adaptation to climate change. New climate change adaptation approaches with nomadic culture characteristics should be exploded in the context of climate warming. In this paper, the different utilization pattern of grassland in different regions, the different modes of production and management and historical culture were analyzed first in Nenjiang–West Liaohe plain and Ke’erqin region, Inner Mongolia Plateau and Ordos Plateau. Then, nomadic culture on the grassland was discussed from the productivity to biodiversity, from local livestock variety to resource-used system. Finally, new approaches of climate change adaptation with inheriting the essence of nomadic culture were proposed, including protecting biodiversity and using resources reasonably, performing a practice of grazing suspension–rotational grazing system, fencing degenerated grassland to facilitate its growth, founding new farming and husbandry system on the grassland, and establishing an incentive mechanism favorable to grassland and ethical cultural protection.     

Global climate change and the politics of disaster

The paper explores the potential political impact of global climate change and, more generally, of natural disaster. Because the affluent West has largely tamed the natural and the social domains, popular clamor for government to anticipate, prevent, and redress disaster increases. I delineate several consequences of the new politics of disaster.     

中国气候变化的科学新认知

The impact of climate changes on mass events in China

There is an increasing number of “mass events” in mainland China. My study extends the current studies to the context of China and tries to examine the potential impacts of climate changes on human conflicts in China. The results suggest a strong linkage between the deviation of monthly mean temperature from the historical mean and the number of mass events in a province. If the current trend of warming persists, in the next 6–8 decades, the number of mass events in China will increase by over 8.8%.     

Competition gives way to cooperation: rethinking Sino-Indian relations in climate change negotiations

In global climate change politics, China and India have worked closely with each other, representing two big emitters from the developing world. This article reviews Sino-Indian cooperation during four UN climate change negotiations from 2009 to 2012. Their collaboration echoed the perception of neorealism in international relations (IR) studies that states will seek “external balancing” for maximizing national “relative gains”. China and India are expected to continue their cooperation on climate change issues when sharing the same structural position as big economies and big emitters, the same pressure in carbon emission reductions, and the same goal of improving living standards for their citizens. Encountering the devastating impacts of climate change and the deadlock in responsibility division in current global climate change governance, this work seeks to shed light on the evolving multilateral governance environment and its complex implications for Sino-Indian relations from an IR perspective.     

European winegrowers’ perceptions of climate change impact and options for adaptation

A questionnaire on the perception of climate change and the impact of climate change was distributed among winegrowers in France, Germany, and Italy. These countries are located in three macro-climatic regions that experienced different patterns of climatic change in the twentieth century—Atlantic, transition to Continental and Mediterranean. The majority of winegrowers perceived changing climatic conditions in the last few decades. The characterization of these changes is consistent with results obtained by the analysis of long-term trends in climatic records. The winegrowers noted impacts on harvestable quantities (mainly in Italy), must quality, and risks of pests and diseases. The majority of respondents (66%) indicated an impact on wine quality, which was perceived as quality improvement in 55% of the cases. Perceived impacts on pests and diseases were reported in 56% of the responses. A strong majority of this group (80%) also reported increasing threats. Perceived climatic change and its noticeable impacts has led to growing interest in adaptation options, combined with a need for more information, among winegrowers. Thus, the transfer of technical knowledge from scientific research to practice is necessary for adaptation. Plans for adaptation by a change of wine varieties were reported with substantially different results among the regions. A majority of German growers said they would consider changing varieties to adapt to warming temperatures, while only a minority of the Italian and French growers said they would consider such changes. However, readiness to adopt adaptation measures is correlated with the degree of changes already planned, independent of climatic change.     

Climate change and village adaptation impact on reliability of irrigation wells in China

This paper builds a water supply reliability econometric model to analyze climate changes and adaptation impact factors on water supply reliability of irrigation wells by using 100 villages’ three-year (2010–2012) field survey data of five middle and eastern provinces of China. The results show that long-run climate change factors, adaptation measures, village-level organizations of irrigation management, as well as extreme climate factors affect the water supply reliability of irrigation wells significantly. Meanwhile, there are significant differences impacting different crops and provinces. This paper suggests that agriculture meteorological disaster monitoring and warning systems should be strengthened by increasing irrigation facilities construction and maintenance, promoting reform of agricultural irrigation water management system, and developing various forms of peasant cooperation organization in order to improve agricultural production capacity to adapt to climate change.     

Migration drivers in mountain regions in the context of climate change:A case study in Shangnan County of China

Climate change has become widely accepted as a challenge that humans will face in the not-too-distant future.Mountain ecosystems and their inhabitants are among the most vulnerable to climate change.This paper seeks to explain migration drivers in specific mountain regions in the context of climate change based on Foresight’s conceptual framework.A climate change sensitive field named Shangnan County in southern Shaanxi Province is chosen as the case study area to investigate local migration drivers.A series of qualitative research methods is employed in the case study including participant observation,semi-structured interviews,and focus group discussions.The evidence of survey suggests that migration decisions are not only shaped by macro factors in aspects of environmental,economics,demographic,social,politics and psychological,but also influenced by placed-related barriers and facilitating mechanisms and personal characteristics.     

中国生物多样性保护适应气候变化的对策

基于气候变化对生物多样性影响的总结分析,初步提出了我国生物多样性保护适应气候变化的对策。气候变化对生物物候、分布、迁移活动、群落结构、栖息地质量、生态系统和景观多样性都产生了一定影响,未来将产生更深刻的影响。我国生物多样性保护适应气候变化需要从物种有效保护、自然保护区规划与管理、灾害防御等方面进行。     

Geopolitics of global climate change and energy security

Currently,the problem of climate change is already far beyond the category of scientific research,and it affects the economic operation mode,interests pattern,and geographical relationships and becomes the focus of global governance.During the transition period of the international economic and social development and the critical transformation period of the world geopolitical pattern reorganization,China’s industrialization is still at the intermediate stage,and tackling with climate change is also China’s internal demand under this development stage.With more influence of climate change on national competitiveness,climate change and geopolitics present complex multiple relations,and climate change in the era of geopolitical landscape gradually affected the national strategy and diplomacy.This article offered some relevant suggestions based on evaluating the new geopolitical characteristics of climate change:(1)weighing of interests and properly handling the complex relations among major powers during international climate negotiations;(2)strengthening risk judgments and actively cooperating with the United States and the European Union on energy and climate change;(3)relying on the"One Belt(Silk Road Economic Belt)and One Road(twenty-first century Maritime Silk Road)"to ensure China’s energy security and actively participating in the global energy governance;(4)strengthening the"south-south cooperation"mechanism innovation and increasing the investment.     

Loss and damage related to climate change: connotations and response mechanism

Global mitigative and adaptive efforts have not been able to effectively address the adverse impacts caused by climate change. Therefore, a direct solution is needed to address the significant resulting loss and damage (L&D). During the United Nations Framework Convention on Climate Change held in Doha in 2012, the issue of responding to L&D arising from climate change gained sudden traction and became one of the key issues that affected the outcome of the convention. In this paper, a study on the definition and connotations of L&D arising from climate change was conducted, together with an analysis of its relationship with related concepts, namely impacts, vulnerability, and risks. This led to the proposal of an L&D conceptual model that is more comprehensive, with the recognition of the need to address the issue through effective supplementation of existing mitigative and adaptive efforts. A systematic elaboration of an L&D response mechanism was made based on politics, law, and the market, leading to a preliminary presentation of a possible format for an L&D mechanism. Potential academic research directions for L&D were also proposed that could serve as references for the establishment of international and national L&D response mechanisms and related research.
