Climate change is one of the most active research fields currently, which has attracted extensive attention from the international community. In order to better understand the development situation and research status of international climate change science, in this paper we took the SSCI and SCI databases as data sources, collected the relevant literatures since 1900 based on the key words related to climate change, and made some statistics and analysis of the literatures of the past one hundred years to reveal the development process of climate change research as well as the development and evolution of its research topics and hot spots. The results showed that the climate change research began in the late 18 th century and early 19 th century, and the academic debate about global warming and global cooling started in the early 1970s. The international programs and projects led by a range of international organizations and intergovernmental bodies have contributed significantly to the rapid development of climate change research. The United States and the United Kingdom have long been the core countries of climate change research. The proportion of Chinese papers has risen rapidly in the last decade. The intensity and scope of scientific research cooperation are constantly expanding. Current research focuses on climate model/modeling, climate simulation, climate policy, climate sensitivity, climate change impacts, climate change adaptation, climate change mitigation, and rate of climate change.  相似文献

未来不同排放情景下气候变化预估研究进展   总被引:10,自引:1,他引:10  
概述未来不同排放情景下气候变化预估研究的主要进展。首先,对用于开展气候变化预估研究的不同复杂程度的气候系统及地球系统模式及其模拟能力进行了简要的介绍,指出虽然目前气候系统模式在很多方面存在着较大的不确定性,但大体说来可提供当前气候状况的可信模拟结果;进而介绍了IPCC不同的排放情景,以及不同排放情景下全球与东亚区域气候变化预估的主要结果。研究表明,尽管不同模式对不同情景下未来气候变化预估的结果存有差异,但对未来50~100年全球气候变化的模拟大体一致,即全球将持续增温、降水出现区域性增加。在此基础上,概述了全球气候模式模拟结果的区域化技术,并重点介绍了降尺度方法的分类与应用。同时对气候变化预估的不确定性进行了讨论。最后,对气候变化预估的研究前景进行了展望,并讨论了未来我国气候变化预估研究的重点发展方向。  相似文献

Global environmental change shapes places and people through ongoing transformation of ecological, socioeconomic, political, and cultural phenomena. One region construed as highly vulnerable to global environmental change, particularly anthropogenic climate change, is the North. Recent research about human communities in Western arctic and subarctic places revolve around vulnerability to anthropogenic climate change, focusing on loss of the ability to pursue traditional livelihoods, threats to ecosystems sustaining human communities and the need to adapt to new environmental regimes. Fewer studies address Russia and the perceptions and emotions related to climate change. To understand how people of the Russian North engage with climate change, I conducted ethnographic research in two rural and remote communities in subarctic alpine Kamchatka, Russia in 2009–2010. Local narratives about climate change largely reflect climate skepticism, and anthropogenic climate change is rejected as explaining environmental changes because: (1) climate is considered as naturally and cyclically changing, (2) humans are not considered a large enough force to alter natural climate cycles, (3) environmental problems are solvable with technology and (4) there is a lack of knowledge about climate change science. Thus, perceptions and emotions about transformation focus on other realms—socioeconomic, political, cultural—that are perceived as more critical to everyday life in the present and near future. Here, I describe these narratives and place the regional understanding of climate change in greater context to explain resistance to imagining environmental transformations due to climate change.  相似文献

Cities are not only major contributors to global climate change but also stand at the forefront of climate change impact. Quantifying and assessing the risk potentially induced by climate change has great significance for cities to undertake positive climate adaptation and risk prevention. However, most of the previous studies focus on global, national or regional dimensions, only a few have attempted to examine climate change risk at an urban scale and even less in the case of a recent literature review. As a result, a quantitative assessment of climate change risk for cities remains highly challenging. To fill this gap, the article makes a critical review of the recent literature on urban-scale climate change risk assessment, and classifies them into four major categories of studies which jointly constitute a stepwise modelling chain from global climate change towards urban-scale risk assessment. On this basis, the study summarizes the updated research progresses and discusses the major challenges to be overcome for the seamless coupling of climate simulation between different scales, the reproduction of compound climate events, the incorporation of non-market and long-lasting impacts and the representation of risk transmission insides or beyond a city. Furthermore, future directions to advance quantitative assessment of urban-scale climate change risk are highlighted, with fresh insights into improving study methodology, enriching knowledge of climate change impact on city, enhancing abundance and accessibility to data, and exploring the best practice to provide city-specific climate risk service.  相似文献

基于气候变化影响的水资源评价对水资源规划和管理具有重要意义,随着全球气候变化影响的加剧,这一研究显得越来越紧迫。在目前的气候变化研究中,很少考虑气候自然波动的影响(气候自然变异),常将所有的变化单独归因于气候变化的影响,这在气候变化的影响评价中可能导致错误的理解与判断。气候自然变异分析由于缺乏超长系列的数据资料而长期被人为避开。针对这一问题,本研究提出模型方法体系,通过历史基准期的长系列模拟来分析气候自然变异的影响。选取常用的1961~1990年水文系列作为基准期,提出一种基于拉丁超立方体抽样技术的季节分段抽样模拟方法,实现对气候自然变异的模拟。应用水文模型TOPMODEL对基准期的径流系列进行模拟,基于不确定性分析GLUE方法对基准期内水文模型参数不确定性进行分析,并探讨了气候自然变异的影响。研究结果表明,在气候变化影响评价中,气候自然变异的影响不可忽略,应在气候变化的影响中加以区分和界定。  相似文献

Based on the questionnaire survey, this paper analyzes China’s public perception of climate change in terms of several influence factors and some empirical findings are obtained. We find that some respondents are willing to take individual actions to address climate change, and they pay more attention to climate change or approve that climate change does harm to residents and society; meanwhile, they tend to have confidence in the government to deal with climate change or believe that fiscal and taxation policies are the effective policy measures. However, there are also other respondents unwilling to take actions and argue that climate change proves the natural consequences. Thus, in order to motivate the public to take actions, the paper suggests that the government should widespreadly disseminate relevant knowledge about climate change to the public and guide the work to address climate change and adopt proper fiscal and taxation policies.  相似文献

青藏公路沿线多年冻土对气候变化和工程影响的响应分析   总被引:10,自引:5,他引:5  
青藏公路沿线工程和气候变化影响下多年冻土变化监测表明,多年冻土对工程活动和气候变化的响应过程存在着较大差异,不同年平均地温的多年冻土使这种差异变得更为明显.分析结果表明:气候变化下低温多年冻土变化要大于高温多年冻土,工程状态下低温多年冻土变化要小于高温多年冻土;气候变化引起的低温多年冻土变化要大于工程对其的影响,而高温多年冻土正好相反.造成这一结果原因主要是由于在工程建设完成初期,相对于气候影响,工程作用对多年冻土的影响具有放大作用,这使得工程状态下多年冻土对气候变化基本没有响应.按照气候影响下多年冻土温度年变化速率来推测,低温多年冻土表面温度升温到工程状态需要50a左右时间,高温多年冻土需要20a左右.6m深的低温多年冻土温度升温到工程状态需要20a,高温多年冻土仅需要5~8a.  相似文献

The international climate change negotiation has been carried out over 20 years. The issue of climate change has shifted from a scientific question into a complex political matter which is related to the sustainable development of mankind. Based on the overview of major processes and stages of international climate conferences, this paper analyzed the key measures that major countries have taken to address climate change, as well as the primary tasks of Paris climate conference and recent international actions. The recent international climate policy issues were also analyzed in order to provide suggestions for China’s activel participation in the development of a new round of international climate change system.  相似文献

Climate change has profoundly impacted the development of human civilization. It is one of the basic forces that have led to the rise and fall of regional civilization. The manifestations and ultimate consequences of the impacts of climate change on social development are the products of the interaction between climate change and human society, which are both related to the characteristics of climate change and to the adaptation of human society. Based on the published papers on climate change and civilization during the past 20 years, five patterns of the impacts of climate change on civilization were summarized. They are periodic changes, pulse, adaptive transition, collapse, migration and replacement. Periodic changes and pulse occurred when climate change impacts were within the resilience of human social systems. Thus, there was no need for major structural changes in the human society. Adaptive transition was a fruit of successful response of the human system when the extent of abrupt climatic change or the trend of climate change exceeded the available range of human social systems In contrast, collapse was a result of failed response of the human system. Migration and replacement, in which people moved from their original living place to other regions and sometimes even replaced the aboriginal civilizations with the colonized civilization, could occur no matter the impacts of climate change had exceeded the resilience of human system. The summarization is expected to be useful for the understanding of the mechanism on the relationship between climate change and civilization, and for coping with the challenges of future global climate change.  相似文献

This study investigates how extreme flows in the Grote Nete watershed located in the Flanders region of Belgium will respond to climate change and urban growth using the hydrological model WetSpa. Three climate change scenarios (low, mean and high), three urban development scenarios (low, medium and high) and the nine combined climate–urban change scenarios are considered. The results indicate that extreme low flows would decrease noticeably by climate change, while they would be less sensitive to urban development. On the other hand, extreme peak flows are predicted to increase considerably due to both climate change and urban growth. It is concluded that coupling the effects of land use change with climate change may lead to severe increase in the frequency river floods in winter as well as the frequency of extreme river low flows in summer.  相似文献
