CO2 is one of the primary greenhouse gases impacting global climate change, making it crucial to understand the spatiotemporal variations of CO2. Currently, commonly used satellites serve as the primary means of CO2 observation, but they often suffer from striping issues and fail to achieve complete coverage. This paper proposes a method for constructing a comprehensive high-spatiotemporal-resolution XCO2 dataset based on multiple auxiliary data sources and satellite observations, utilizing multiple simple deep neural network (DNN) models. Global validation results against ground-based TCCON data demonstrate the excellent accuracy of the constructed XCO2 dataset (R is 0.94, RMSE is 0.98 ppm). Using this method, we analyze the spatiotemporal variations of CO2 in China and its surroundings (region: 0°–60° N, 70°–140° E) from 2019 to 2020. The gapless and fine-scale CO2 generation method enhances people's understanding of CO2 spatiotemporal variations, supporting carbon-related research. [ABSTRACT FROM AUTHOR]

This paper proposes a conceptual and analytical framework of states' legitimacy-seeking to comprehensively investigate the motivation behind China's climate and environment policy. While previous research has largely overlooked political factors that underlie China's climate policy, this paper argues that these factors are crucial in understanding China's policy changes, which are evident at both domestic and international levels. By examining sources such as government documents, leaders' speeches and authoritative literature, this study contends that China's climate change initiatives are part of a broader effort to enhance domestic and international legitimacy. The issue of climate change has become highly politicised in China under the leadership of President Xi Jinping, and it serves as a crucial test of the ruling party and the state's capacity to govern effectively. As such, legitimacy-seeking is the key driver that links China's domestic measures and international commitments. [ABSTRACT FROM AUTHOR]

Adaptive farming behavior is a key strategy for farmers to cope with climate change. This paper aims to explore the potential impacts of climate change information sources on farmers’ adaptive farming behavior. This paper clarifies the internal mechanism of three typical information sources, namely government departments, scientific research institutions and neighborhood communication, affecting farmers' adaptive farming behavior. Based on the sample data of 1200 farmers in the main wheat producing areas of Shaanxi Province, the theoretical conjecture is empirically tested. The results showed that the climate change information from government departments and scientific research institutions has a significant positive impact on farmers' adaptive farming behavior, but in the case of considering the three sources of information at the same time, the information source of scientific research institutions has the strongest positive impact on farmers' adaptive farming behavior. After farmers have access to climate change information exchanged by government departments, scientific research institutions and neighbors, their differences in climate change adaptive farming behavior mainly depend on their climate change cognition rather than subject trust factors. Formally organized climate change information represented by government departments and scientific research institutions has a more significant positive impact on farmers' adaptive farming behavior, but this impact depends largely on whether the information obtained by farmers can improve their climate change awareness.

Henan Province is the birthplace of Chinese civilization and one of the earliest human settlements, which means that the area has an important national cultural heritage. Traditional villages are an important facet of this cultural heritage, and studying their spatiotemporal characteristics in different periods has important theoretical and practical significance for the sustainable development and protection of cultural heritage in the region. This paper takes the traditional villages of the Yellow River basin in Henan Province that were formed before 1919 as the research object. Information on the ancient river was obtained through a literature search as well as via field research, and the important tributaries of the Yellow River in different periods were mapped using ArcGIS 10.0 software. The nearest neighbor index, kernel density estimation, standard deviation ellipse and other methods were adopted to analyze the spatiotemporal characteristics of the traditional villages. The factors that influenced the evolution of traditional villages were explored in depth by combining changes in the course of the river and water conservancy projects. The results show that the formation of traditional villages along the Yellow River in Henan Province has experienced a historical track of growth, contraction, growth and prosperity and stability. The traditional villages along the Yellow River in Henan Province generally show a clustered pattern, forming a dense concentration of traditional villages in the middle reaches of the Yellow River. The center of gravity shows a migration trend from southeast to northwest. In terms of influencing factors, the spatiotemporal evolution of the relationship between villages and their distance to water is closely related to climatic fluctuations, changes in channel, water conservancy projects and social and cultural factors. This paper deepens our understanding of the relationship between traditional village evolution and watersheds by improving the consistency between village spatial distribution and historical geography and provides a useful theoretical reference for the sustainable development of China's traditional villages.

The politics of international finance for coal power plants have intensified since the 2015 Paris climate agreement was negotiated. Over the past few years, Japan and South Korea have signaled their intent not to fund new coal projects overseas, leaving China and its Belt and Road Initiative as the 'financier of last resort.' In September 2021, China too announced its intent to stop providing finance for overseas coal projects. What accounts for their decision to cease financing overseas coal projects despite prominent differences in political systems, degree of internationalization of their financial systems, and economic size? Drawing on datasets of coal projects and financing supplemented by case material and interviews, this paper explores the dynamics of coal export finance and how the combination of international reputational pressures and declining demand for coal finance diminished the domestic support for incumbent coal exporters in all three countries.

The influences of human activity on regional climate over China have been widely reported and drawn great attention from both the scientific community and governments. This paper reviews the evidence of the anthropogenic influence on regional climate over China from the perspectives of surface air temperature (SAT), precipitation, droughts, and surface wind speed, based on studies published since 2018. The reviewed evidence indicates that human activities, including greenhouse gas and anthropogenic aerosol emissions, land use and cover change, urbanization, and anthropogenic heat release, have contributed to changes in the SAT trend and the likelihood of regional record-breaking extreme high/low temperature events over China. The anthropogenically forced SAT signal can be detected back to the 1870s in the southeastern Tibetan Plateau region. Although the anthropogenic signal of summer precipitation over China is detectable and anthropogenic forcing has contributed to an increased likelihood of regional record-breaking heavy/low precipitation events, the anthropogenic precipitation signal over China is relatively obscure. Moreover, human activities have also contributed to a decline in surface wind speed, weakening of monsoon precipitation, and an increase in the frequency of droughts and compound extreme climate/weather events over China in recent decades. This review can serve as a reference both for further understanding the causes of regional climate changes over China and for sound decision-making on regional climate mitigation and adaptation. Additionally, a few key or challenging scientific issues associated with the human influence on regional climate changes are discussed in the context of future research. [ABSTRACT FROM AUTHOR]

CARBON offsetting , *CLIMATE change ,CHINA-United States relations ,PARIS Agreement (2016) - Abstract
The United States (U.S.) and China are key to meeting the goals of the Paris Agreement and reaching carbon neutrality by around mid-century. Despite differences, carbon neutrality will be met more rapidly if the two countries coordinate and facilitate synergies in carbon-neutral technologies and policy development and implementation. Building on long-term pathway models in the U.S. and China, current emissions trends and sources, and a policy analysis, this paper puts forward a novel framework for U.S.-China coordination on carbon neutrality. The analysis reveals similar technology and policy pathways, policy gaps, and shared milestones for decarbonization in 2030, 2040, and 2050-2060. The main technological pathways focus on reductions in energy demand and non-energy-related CO2 emissions, decarbonization of electricity and fuels, and increases in electrification rates and CO2 sequestration. Given existing domestic policies and opportunities for further action, areas for coordination on carbon neutrality include common policy milestones; dialogue and technical exchange; research, development, and demonstration (RD&D); and international climate leadership. Despite escalated tensions between the U.S. and China, and challenges for climate cooperation, coordination between both countries on carbon neutrality is both possible and necessary. Carbon neutrality will be met more swiftly if the U.S. and China coordinate and facilitate synergies in carbon-neutral technologies and policy. Despite the rise in geo-political tensions between the U.S. and China, coordination on carbon neutrality is both possible and necessary. An analytical framework for U.S.-China coordination on carbon neutrality, includes technology and policy pathways, and common milestones of key sectors' decarbonization for 2030, 2040, and 2050-2050. The two countries could coordinate on common policy milestones, dialogue and technical exchange, research and development, and international climate leadership. [ABSTRACT FROM AUTHOR]

Urban areas mediate climate transformations and generate new forms of climate urbanism. Looking at climate action in the twelve fastest-growing cities in China with under one million people, this paper proposes a perspective on urban climate politics 'from elsewhere' that foregrounds the potential role of smaller urban areas in mediating climate transformations. The analysis reveals three climate action strategies that reflect practical, institutional, and personal spheres of climate transformations. Planning action in the personal sphere provides opportunities for urban transformations. A perspective 'from elsewhere' calls for greater attention to planning for diverse change strategies for climate transformation. [ABSTRACT FROM AUTHOR]

Carbon neutrality is an important policy in the current global response to climate change and has been widely recognized by various industries. In the process of promoting carbon neutrality, new energy plays a pivotal role. In this study, the definition and connotation of new energy and its role and specific operation in the energy transition of carbon neutrality are firstly explained. Promoting new energy development requires significant green and low-carbon investments. Taking China as an example, this paper analyzes the opportunities brought by the carbon neutral process to the field of green finance and analyzes the main features and development trends of green finance in China at present. Then this paper proposes policy recommendations to strengthen the development of green finance in China in terms of improving the green financial policy system, enhancing the supply capacity of green financial services, and optimizing the supporting environment for green financial development. Finally, this paper analyzes the measures and experiences of the United States in promoting low-carbon development and proposes countermeasures for China's low-carbon development on the basis of the five major relationships that need attention in China's carbon-neutral process. That is, strengthen the top-level design and improve the regulatory policy system; optimize the energy structure and increase the proportion of clean energy; optimize the industrial structure and reduce energy consumption in key industries; build a complete low-carbon technology system and promote low-carbon technology research and development and demonstration applications, and encourage local conditions to explore low-carbon development paths. The development of green finance can contribute to the advancement of new energy technologies, thus contributing to the achievement of carbon neutrality goals. [ABSTRACT FROM AUTHOR]

Climate change has a significant impact on agriculture so it is necessary to adapt to climate change to promote agricultural transformation and sustainable development. The key to achieving such a goal is to promote the development of climate smart agriculture (CSA) against the background of climate change. The paper first uses official statistical data to evaluate the effect of climate smart agricultural technology project, and then uses the statistical method of questionnaire survey to further investigate and statistically analyze the implementation effect of climate smart agricultural technology project in the pilot area. Further, semi-structured interview method is employed to conduct more in-depth investigation and analysis on some main topics on the basis of preliminary investigation and statistical analysis. The interviews focus on the environmental and economic effects of project practice, the difficulties of smallholder farmers' technology extension, and the farmers' willingness to participate. The study indicates that to promote climate smart agriculture technologies is an effective way to solve agricultural problem in practice under the background of climate change, and can achieve at least three benefits. The first is to reduce production costs, which can be reduced by 10% to 15% in terms of fertilizers and pesticides alone. The second is to improve productivity, and preliminary results show that food production can be increased by more than 5%. Finally, it has carbon sequestration capabilities and can significantly reduce greenhouse gas (GHG) emissions. Therefore, the promotion of climate smart agriculture (CSA) technologies helps to solve the problem of agricultural transformation and sustainable development. To this end, it is necessary to drive the transformation and optimization of regional agricultural ecological environment and production system, and promote the innovation and extension of CSA technology. In addition, some soft conditions (e.g., talent, system and technology, etc.) and hard conditions (e.g., modern agricultural supply chain, agricultural big data and the Internet of Things, etc.), must be created, too.

The balance between agricultural development and maintenance of agro-ecological environment becomes a huge challenge because of global climate changes. Existing literature on the low-carbon pilot policy proposed by the government of China and whether the problems of agricultural development and agricultural environmental protection can be solved or not have not been reviewed. This paper analyzes the impact of low-carbon pilot policies on agricultural eco-efficiency by using SARAR model based on the data of 281 cities in China. Results show the spatial spillover effects between low-carbon pilot policies and agricultural eco-efficiency. The implementation of low-carbon pilot policy can improve agricultural eco-efficiency. Although restrained by agricultural economic development, this policy has disequilibrium effect on agricultural eco-efficiency, has a relatively large impact on agricultural eco-efficiency in western China and other poor areas, and promotes the reduction of agricultural carbon emission. The effect of the implementation of low-carbon pilot policy is affected by the initial agricultural economic development and urban economic conditions. This research aims to improve the agricultural eco-efficiency and enforce the green development of the agricultural economy via the perspective of the low-carbon pilot policy. [ABSTRACT FROM AUTHOR]

As researchers suggested, there is no way back for transatlantic politics; it has suffered severe setbacks that cannot be undone in recent years. Although the Biden win promises opportunities for EU-US cooperation, the EU's drive for strategic autonomy would not turn a halt given that the great leap forward for European policymakers and strategists would be to acknowledge that Europe's "autonomy" is actually in the transatlantic interests. Nevertheless, the transatlantic partnership is torn from a "thickening" tie that has bound the US and EU together for decades. Consequently, President Biden's transatlantic strategy to retie would undoubtedly pose challenges for European relations with China. The United States is increasingly intent on decoupling its economy and its technology sector from China as part of the new cold war cliché between the two. Nevertheless, the EU-China partnership has been working closely for the past few decades, and China's market has a great appeal to the world. The time has come for the EU to consider how to survive the turmoil of US-China decoupling caused by the two superpowers' agendas. This paper analyzes the critical transformation in light of not only the politics of today but also the structural trends in the global balance of power between the US and China. And explains the reasons why the pitfalls of US-China decoupling shape the dynamics of European ties with China in the last decade. This paper focuses on the issues: i) The EU's alterations of the EU-China partnership dealing with an increasingly assertive China; ii) US and China on the path to inevitable economic decoupling; iii) The EU drives for strategic autonomy aiming at enhancing the competitiveness in the high tech sector; iv) EU's ambition of safeguarding and reinvigorating cooperation over climate change and global health through the engagement of EU-China Investment Agreement.

There has been increasing interest in whether low carbon cities developed under Chinese institutional arrangements can facilitate a transformative change. Unlike their western counterparts, Chinese low carbon cities are mainly developed through a top-down approach characterized by strong regulatory influences and centrally-led pilots. Inspired by insights from institutional theory, this paper assessed the progress that has been made in Chinese low carbon cities through understanding urban actors' willingness and capacity to pursue more radical changes. Based on semi-structured interviews and documentary analysis, it is found that due to the low recognition of the intrinsic value of carbon reduction, low carbon transition was largely represented as a practical discussion around national binding targets and local economic development. Following this, it is suggested that any attempt to speed up urban low carbon transition should consider strengthening incentive structures for cultural or paradigm change. [ABSTRACT FROM AUTHOR]

Although ski tourism in China is experiencing a boom, and the number of operating ski areas has significantly increased, the influence of climate change on the future development of China's ski industry has so far largely been overlooked. This paper addresses this important gap by applying the ski season simulation model SkiSim 2.0 at 116 ski areas. Four main indicators of climate change impact were examined: ski season length, operational ski days in economically important season segments, technically produced snow and snowmaking requirements. For all ski resorts in China and all climate change scenarios, average ski seasons are projected to shorten (− 4 to − 61% RCP 4.5; − 6 to − 79% RCP 8.5 in the 2050s) while snowmaking needs increase (27 to 51% RCP 4.5; 46 to 80% RCP 8.5 in the 2050s). The results indicate that high regional differences in climate change vulnerability exist. The implications for altered competitiveness and development potential of the ski industry in China are discussed. [ABSTRACT FROM AUTHOR]

This paper matched the data for all non-financial listed firms in China from 1990 to 2017 with weather data and used temperature and precipitation to represent climate change. Using daily temperature and daily precipitation data, we constructed temperature bins and precipitation bins. This study presents a potential first empirical analysis that applies the risk perception theory to comprehensively examine the impacts of daily temperature and daily precipitation on firms' debt financing costs. Compared to a day with a suitable temperature, a day with temperatures above 30 °C increases firms' debt financing costs by 0.2411%. Compared to a sunny day, a day with torrential rain increases firms' financing costs by 0.2697%. Approximately $122.13 million and $20.49 million in extra costs were incurred across all firms in 2017. We conducted a series of heterogeneity tests. We found that the negative impacts of climate change on debt financing costs are greater for firms that investor considers more vulnerable. Finally, we found two possible mechanisms. First, from the firm's subjective initiative perspective, firms that respond proactively during seasons of high temperatures and heavy rains can reduce the negative impacts. Second, adverse weather caused by climate change may also increase firms' debt financing costs by blocking travel. These results enrich the literature on firms' debt financing costs and contribute to the understanding of climate change's impact on firms. [Display omitted] • An extra high-temperature day increases firms' debt financing cost by 0.2411%. • An extra heavy-rain day increases firms' debt financing costs by 0.2697%. • The negative impacts will be greater for those firms that investor considers more vulnerable. • Firms' response proactively can reduce the negative impacts. • Climate change also may increase firms' debt financing costs by blocking travel.

Terrestrial vegetation plays pivotal roles on land-atmosphere interactions, and even global climate change. However, limited attempts have been taken to elucidate the responses of vegetation activity to weather-related drivers (e.g., droughts, floods). This is especially in China with vast area and changeable meteorological conditions. In this paper, the performance of two satellite-based indices, namely vegetation condition index (VCI) and vegetation health index (VHI) were analyzed to detect the vegetation responses to weather-related variations. The dynamics of vegetation activity in China were further examined for the period 1982–2013. We found widely-distributed vegetation stresses in the entire country for a long period (about an average of two months per year) from the VCI and the VHI. In addition, both the two indices indicated increasing vegetation activities over most parts of China during 1982–2013. However, there is no consensus between the two indices at spatial pattern and regional totals. This discrepancy can be due to the negative-correlation assumption of the VHI between the VCI and bright temperature. However, we found that the relationship between the VCI and temperature could be changeable in different regions, especially in China with complex topography, diverse climate conditions and different vegetation types. The findings of this paper highlight the necessity to account for dominant controls on vegetation growth when using the VCI and the VHI to analyze vegetation activity. [ABSTRACT FROM AUTHOR]

There has been a growing focus on uncertainty as a distinct concept in the risk literature. This paper is concerned with how those involved in the design and implementation of climate change policy conceptualize risk and uncertainty. Based on interviews with policy and industry elites in Australia, China and the UK, it finds that participants did not distinguish between "risk" and "uncertainty" in their conceptualization of climate threats. For the majority of them, politics was the most significant source of risk and uncertainty in climate policy, but delegation of otherwise political decisions to the market was seen as the best solution. The conclusion suggests that the conceptual distinction between risk and uncertainty is less important, for policy and industry elites, than the need to develop mechanisms that account for both persistent scientific uncertainties as well as interpretive and moral ambiguities in climate policy design and implementation.

This paper investigates the effects of prenatal exposure to extreme temperatures on birth outcomes—specifically, the log of birth weight and an indicator for low birth weight—using a nationally representative dataset on rural China. During the time period we examine (1991–2000), indoor air conditioning was not widely available and migration was limited, allowing us to address identification issues endemic in the climate change literature related to adaptation and location sorting. We find substantial heterogeneity in the effects of extreme temperature exposure on birth outcomes. In particular, prenatal exposure to heat waves has stronger negative effects than exposure to cold spells on surviving births. [ABSTRACT FROM AUTHOR]

Climate change poses a potential risk to coastal infrastructure, thus threatening the economics or even the safety of human beings. Thus, a better understanding of the attitude of port organizations toward climate adaptation and mitigation is essential. This paper addresses this research gap by investigating 18 port organizations in China. The questions include the impediments and the impact of context, systems, and other factors on the implementation of adaptation strategies. The results indicate that port organizations are generally aware of climate change impacts and agree that some further steps are needed. However, policy support serves as a key factor in implementing adaptation plans. Apart from offering important insight on the attitude of port organizations, the study also serves as a platform for further research on climate adaptation planning in China. [ABSTRACT FROM AUTHOR]

China has achieved a great success in control and elimination of key parasitic diseases. In 2007, the elimination of lymphatic filariasis was verified by WHO. The schistosomiasis incidence and snail-distributed areas have reduced to the lowest level in the history. The transmission and disease burden of echinococcosis have been contained largely, and the populations infected with soil-transmitted trematode and food-borne parasites have also shown a significantly declining trend. Because of rapid globalization and climate changes, however, many new challenges have arisen. In his paper, the 2020-2030 roadmaps towards the control and elimination of these key parasitic diseases are described. Moreover, China is actively implementing its global health strategy, and will be more and more engaged into global health affairs, in which a series of China-Africa health cooperation projects have been in planning with a wish of making a greater contribution to the SDGs.

The Cryogenian is a critical period in the history of the Earth. It is marked by multiple extreme climate changes that caused alternating global glacial and interglacial intervals. These dramatically changed the sedimentary system, and metal ores and source rocks distributed widely during this period. Therefore, studying the Cryogenian stratigraphic framework and sedimentary basins is important to improve the stratigraphic resolution for metal mineral and hydrocarbon prospecting and exploration in China. This review paper firstly divides three tectonic‐stratigraphic regions in China in the Cryogenian, including the tectonic‐stratigraphic regions of Great South China, Xingmeng‐Tarim, and North China. Secondly, geochronologic data and geological records are combined to clearly depict the Cryogenian sedimentary sequence of continental blocks and micro‐continental blocks in different tectonic‐stratigraphic regions. The results were used to propose a new comparison scheme of stratigraphy for the Cryogenian in China. Finally, according to differences of sedimentary evolution and tectonic evolvement, sedimentary basins and their lithofacies paleogeography are identified and summarized, respectively.

As the world's largest carbon emitter, China is under great pressure to cut down carbon emissions. Understanding the evolution of carbon emissions across Chinese cities is important for policymakers when allocating carbon emission quota among these cities. This paper draws upon the Open-source Data Inventory for Anthropogenic CO2 to calculate city-level per capita carbon emissions in China from 2001 to 2016. Overall, we find that per capita carbon emissions of Chinese cities have been generally on the rise during the 2001–2016 period. However, there has been on average a modest decline in per capita carbon emissions of cities in China's Yangtze River Delta region and Pearl River Delta region from 2011 to 2016, after a remarkable increase during the 2001–2011 period. Besides, the average north-south gap has been enlarged, with northern cities having a relatively higher level of per capita carbon emissions. [ABSTRACT FROM AUTHOR]

• Average start of the photosynthetic period in China was on the 123rd day of the year. • The average start of the photosynthetic period advances at a rate of 4.3 d (10 a)−1. • 64% of the region is temperature controlled, others are precipitation controlled. • Importance of temperature and precipitation determined by pre-season precipitation. • Climate change increases NPP by advancing the start of the photosynthetic period. In the context of global warming, the advancement of spring phenology in northern and temperate regions due to increased temperatures has been widely reported. Early and delayed start of the photosynthetic period (SOP) directly affects the vegetation net primary productivity (NPP). However, the interrelationship between climate change, the SOP, and the NPP is unclear. In this paper, we use the dynamics of decadal daily solar-induced chlorophyll fluorescence data to calculate the response of Chinese vegetation photosynthetic phenology to climate change and its impact on the NPP over the last 20 years. The results found that over the last 20 years, the average SOP in China was on the 123rd day of the year, and the SOP has advanced at an average rate of 4.3 d (10 a)−1, with a faster trend of SOP advancement in highland and high-altitude areas. 64% of SOP in China is controlled by temperature; 36% of the SOP in China is controlled by precipitation, and the relative importance of temperature and precipitation was reversed as the precipitation gradient decreased, with SOP dominated by temperature when pre-season precipitation ≧300 mm, and SOP dominated by precipitation when pre-season precipitation ≦300 mm. Finally, we find that climate change indirectly increases vegetation NPP by advancing SOP. Our study emphasizes the importance of precipitation on phenology. It provides a scientific basis for understanding and predicting the response of spring photosynthetic phenology to climate change and the contribution of spring phenology to carbon estimation in terrestrial ecosystems.

Despite the efforts made by the international community on climate change, since the 1990s, the world has not yet reached an acceptable solution to tackle the problem. Disputes existed not only between the advanced economies and the emerging powers, such as the BRICS states, but also between the emerging developing nations and the least developed nations. The key issue was not about "whether" the climate change should be tackled, but rather on "how" to tackle it, namely, "what" should be done and "who" should make the decisions. As one of the greatest carbon emitters, China has often been blamed being responsible for the failure of reaching a binding international treaty at the Copenhagen Conference, yet China insists that it has the legitimated rights to develop its economy and that the Western nations should take more responsibilities. This paper aims to examine the current international architecture on climate change, and to explore the obstacles that prevented reaching a "fair" solution to tackle the issue, taking China's position as an example. It argues that although the approaches taken by the relevant parties are legitimate under their own circumstances, they are not beneficial to help reach a global solution to save the earth. To ensure more effective governance on climate change, some reform may be required to strengthen the global institutions and rules; but the emerging powers, including China, should also be prepared to bear more responsibilities at the international stage.

Multi-level governance (MLG) theory has become the main explanation for how climate action is realized in polycentric, multi-sector, multi-actor policy landscapes. In this paper, we examine processes of climate change governance in a given city in China, Rizhao, and evaluate how MLG arrangements operate. We do so by examining primary data collected through in-depth interviews with local stakeholders. Our results show that the focus on multi-level – and in particular transnational – interactions obscures the ways in which urban low carbon transitions happen in three ways. First, in spite of Rizhao being a well-known case in environmental politics, there is an absence of international actors and non-governmental organizations operating on the ground. Second, the emphasis on opportunities of local authorities to build political agendas through participation in global networks conceals how structures of power, political-economic coalitions, and technological practices are firmly fixed in a local context. Third, the case study illustrates the enduring authority of formal top-down channels of control in this political system. Based on these results, we caution against the uncritical application of MLG theory to environmental politics in settings where deliberative democracy is lacking and the full benefits of multi-level interactions are unlikely to be achieved.

Highlights • The increases of commuting CO 2 emissions are several times larger than the urban size, population, and economics' developments. • Metro services reducing commuting CO 2 emissions near the metro stations is not statistically significant, possibly because the proportions of car users near the metro stations are similar to the two cities' average levels, which is caused by their higher household income and the longer travel time using the metro. • In Beijing, there are the smallest commuting CO 2 emissions in the outer suburbs due to job-housing balances, short distance and large percentage of non-motorized mode uses while the largest commuting CO 2 emissions in the inner sprawl suburbs due to car trips with long distance. Abstract To understand the changing relationships between commuting CO 2 emissions (CCE), travel behavior and urban forms, this paper provides a comparative study between the typical Chinese cities of Beijing (more developed) and Xi'an (rapidly developing). Further, the effects of metro services on reducing CCE were explored, and comparative analysis on CCE between the inner sprawling suburbs and outer suburbs was conducted. It was found that: (i) the increases in CCE are several times larger than the increases in urban size, population, and economic developments; (ii) metro services reducing CCE near metro stations is not statistically significant, maybe because the proportions of car users near the metro stations are similar to the two cities' average levels, which is caused by their higher household income and the longer travel time using the metro; (iii) in Beijing, there are smallest CCE in the outer suburbs due to job-housing balances, short distance and large percentage of non-motorized mode uses while largest CCE in the inner sprawl suburbs due to car trips with long distance. These findings indicate that to cope with the rapidly increasing CCE, more attention should be paid to developing strong industry and real-estate simultaneously; the improvement in the feeder bus and public bicycle systems should also be reinforced to reduce the total travel time of metro users; and satellite cities with job-housing balance are greatly needed. The implications will benefit efforts to reduce CCE and mitigate global climate change, and they also provide empirical evidence and reference values for other global cities. [ABSTRACT FROM AUTHOR]

With important implications for global climate change mitigation, the development of a cap-and-trade emission trading scheme (ETS) in China is embedded in distinctive political, economic, and institutional contexts and has been attracting increasing attention in recent years. To offer a clear perspective on current research progress, this paper systematically reviews the recent literature on China’s ETS from three main aspects: mechanism design, policy and regional linkages, as well as impact assessment. The current research consensuses are summarized based upon detailed literature analyses and commentaries, and together with observations of international experience and China’s actual condition, the paper provides policy proposals for the development of China’s national ETS during 2016–2020. Finally, several important controversies in the current literature are discussed with regard to the practical demands of China’s ETS development. Five pressing topics that need to be further studied in the coming years are highlighted, including cap setting, allowance allocation among sectors and enterprises, carbon pricing, policy package and unified carbon market construction, as well as ex-ante and ex-post impact assessments.

In view of the climate emergency, it is necessary to model and forecast road transport emissions for implementing more effective climate policy. This paper fills an important research gap by quantifying the challenges, barriers and remedies of achieving road transport emission reduction and air quality improvement in developing countries. It contributes to the debate on top-down and bottom-up approaches to reconcile carbon and other transport related emissions. China and India are chosen as case studies. Using various official statistics and proxy variables, we estimate and compare the road transport carbon emissions of the two countries systematically from 2009 to 2020. Insights from detailed mode-specific estimations of the bottom-up approach are valuable for targeted policies and measures. An analysis of the major components of road transport carbon emissions points to strategies of promoting electric vehicles, reducing transport demand, accelerating modal shift to low-carbon modes, and cleaner electricity to achieve climate policy.

Because China has emerged as the largest greenhouse gas (GHG) emitter in total annual emissions, to accelerate the pace of GHG emission reduction in China is important to the success of global efforts in addressing climate change. Carbon trading is a market mechanism and key instrument in the mitigation of climate change. This paper explores the policy process and development state to date of China׳s carbon-trade market to understand the emergence and development of that market and to understand what barriers are hampering China׳s carbon-trade market development. To achieve this goal, this paper introduces and analyzes China׳s status in the international market, examines the factors driving carbon-market launching by the Chinese government, and traces the development of mandatory carbon-emission trading and voluntary emission trading. It is argued that China׳s carbon-trading market is confronted with challenges such as the absence of a functional carbon-trading market, inaccuracy of the quota allocation, an imperfect trading mechanism, and lagging legislation. At the present stage, shortcomings such as having no real-time carbon price and dominated spot transactions differentiate China׳s trade market substantially from a functional system. A quick market integration of China׳s carbon market appears remote. It is suggested that specific measures be taken to promote the development of the Chinese carbon-trading market.

This paper critically analyses the construction of eco-cities as technological fixes to concerns over climate change, Peak Oil, and other scenarios in the transition towards 'green capitalism'. It argues for a critical engagement with new-build eco-city projects, first by highlighting the inequalities which mean that eco-cities will not benefit those who will be most impacted by climate change: the citizens of the world's least wealthy states. Second, the paper investigates the foundation of eco-city projects on notions of crisis and scarcity. Third, there is a need to critically interrogate the mechanisms through which new eco-cities are built, including the land market, reclamation, dispossession and 'green grabbing'. Lastly, a sustained focus is needed on the multiplication of workers' geographies in and around these 'emerald cities', especially the ordinary urban spaces and lives of the temporary settlements housing the millions of workers who move from one new project to another.

In December 2015, China joined 190 plus nations at Paris in committing to the goal of limiting the rise in global average temperature to ‘well below’ 2°C. Carbon budget analysis indicates that goal will require not only that the European Union and US reduce their emissions by greater than 80% by 2050, but that China at least comes close to doing so as well, if any budget is to be left over for the rest of the world (RoW). Given that RoW emissions are, and will come from, low-income and emerging nations, China’s emission reduction potential is of no small consequence. In this paper, we use the Kaya identity to back out changes in the drivers of CO2 emissions, including gross domestic product (GDP), energy intensity (E/GDP) and the carbon content of energy (C/E), the latter two calculated to be consistent with China’s long-term GDP growth rate forecasts and specified 2050 CO2 emission reduction targets. Our results suggest that even achieving China’s highly optimistic renewable energy targets will be very far from sufficient to reduce China’s CO2 emissions from 9.1 Gt it emitted in 2015 to much below 3 Gt by 2050. Even reducing its emissions to 5 Gt will be challenging, yet this falls far short of what is needed if the world is to meet its ‘well below’ 2°C commitment. Key policy insights Under the Paris Agreement there is great pressure on China to very substantially reduce its emissions by 2050. While China has attached great importance to renewables and nuclear energy development, even achieving the most optimistic targets would not be sufficient to reduce China’s emissions from 9.1 Gt in 2015 to much below 3 Gt by 2050. China’s emission reduction potential falls far short of what is needed if the world is to meet its Paris ‘well below’ 2°C commitment, even if the EU and US reduce their emissions to zero by 2050. Emission cuts consistent with the Paris Agreement will require that China and the world give much greater weight to advancing research and development of scalable low-, zero- and negative-carbon sources and technologies.

Regional precipitation patterns may change in a warmer climate, thereby increasing flood and drought risks. In this paper, annual, annual maximum, intense, heavy, moderate, light, and trace precipitation are employed as indicators to assess changes in precipitation patterns under two scenarios in which the global mean temperature increases by 1.5 °C and 2.0 °C relative to pre-industrial levels using the regional climate model COSMO-CLM (CCLM). The results show that annual precipitation in China will be approximately 2.5% higher under 1.5 °C warming relative to the present-day baseline (1980–2009), although it will decrease by approximately 4.0% under an additional 0.5 °C increase in global mean temperature. This trend is spatially consistent for regions with annual precipitation of 400–800 mm, which has experienced a drying trend during the past half century; thus, limiting global warming to 1.5 °C may mitigate these drying conditions. The annual maximum precipitation continues to increase from present day levels to the 2.0 °C warming scenario. Relative to the baseline period, the frequency of trace and light precipitation days exhibits a negative trend, while that of moderate, heavy, and intense precipitation days has a positive trend under the 1.5 °C warming scenario. For the 2.0 °C warming world, the frequency of days is projected to decrease for all precipitation categories, although the intensity of intense precipitation increases. Spatially, a decrease in the number of precipitation days is expected to continue in central and northern China, where a drying trend has persisted over the past half century. Southeastern China, which already suffers greatly from flooding, is expected to face more heavy and intense precipitation with an additional 0.5 °C increase in global mean temperature. Meanwhile, the intensity of intense precipitation is expected to increase in northern China, and the contribution of light and moderate precipitation to the annual precipitation is expected to decrease in southeastern China. Therefore, flood risk in northern China and drought risk in southern China should draw more attention for a global air temperature increase from 1.5 °C to 2.0 °C. [ABSTRACT FROM AUTHOR]

This paper uses detailed production data from a half million Chinese manufacturing plants over 1998–2007 to estimate the effects of temperature on firm-level total factor productivity (TFP), factor inputs, and output. We detect an inverted U-shaped relationship between temperature and TFP and show that it primarily drives the temperature-output effect. Both labor- and capital- intensive firms exhibit sensitivity to high temperatures. By mid 21st century, if no additional adaptation were to occur, we project that climate change will reduce Chinese manufacturing output annually by 12%, equivalent to a loss of $39.5 billion in 2007 dollars. This implies substantial local and global economic consequences as the Chinese manufacturing sector produces 32% of national GDP and supplies 12% of global exports. [ABSTRACT FROM AUTHOR]

China is the country with the most population in the world, and its climate is extremely diverse due to tremendous differences in latitude, longitude, and altitude, ranging from tropical in the far south to subarctic in the far north and alpine in the higher elevations of the Qinghai-Tibetan Plateau. Accurate assessment of its modern climate change is conductive to addressing global warming threat. Along with the development of Past Global Changes (PAGES) research, the focus has changed from paleo-climate reconstructions to using paleo-data for assessing the present and predicting the future. Previous studies have been devoted to climate change assessment using modern climate observations and simulations. This paper presents a new assessment approach based on the mid-Holocene, which provides a naturally oriented warming that can be compared to modern human-made global warming. A variety of climatic data, including modern observations, paleo-climate records, CMIP5 (Coupled Model Intercomparison Project Phase 5) and PMIP3 (Paleoclimate Modelling Intercomparison Project 3) simulations, as well as lake level models, were applied in this synthesis. Numerical climate classification was introduced to evaluate climate change impacts to Chinese climate zones on various time scales. The results show that winter and summer seasons have different response to the naturally oriented mid-Holocene warming but human-made global warming makes the warming trend appear in all seasons. Temperate and continental dry winter climates expand dramatically during the mid-Holocene warm period; however, the future global warming could have few impacts to Chinese climate zones. Furthermore, the East Asian summer monsoon was strengthened obviously by the mid-Holocene warm climate and strong low-latitude insolation. There is no consistent trend both for the winter and summer monsoon on the background of human-made global warming. In this study, a new benchmark was established based on paleo-climate to evaluate the impacts of human-made global warming. [ABSTRACT FROM AUTHOR]

Crop phenology is co-determined by climate change and crop management. Over recent decades, climate change-related alterations in crop phenology have been observed and reported for various global crops. However, attributing changes in crop phenology to climate change is difficult, because there have been concurrent changes in crop management. In this paper, we isolated and quantified the impacts of climate change and crop management on the changes of wheat phenology in China, during the period 1981–2010, using a first-difference multiple regression model. Our results shows: (1) based on observed phenological data, in spring/winter wheat, the mean sowing and emergence date were delayed by 0.91/2.29 and 0.39/0.73 days decade −1 ; mean anthesis and maturity date advanced by 1.05/2.28 and 0.01/1.42 days decade −1 ; mean length of vegetative growth period (VGP) and whole growth period (WGP) were shortened by 1.09/2.86 and 0.89/3.69 days decade −1 ; mean length of reproductive growth period (RGP) was prolonged by 0.55/0.61 days decade −1 . (2) At most stations, changing direction of wheat phenology affected by isolated impacts of climate change or crop management was consistent with that affected by combined impacts of climate change and crop management. (3) For observed trends of most phenological stages and growth periods, relative contribution from climate change was smaller than from crop management, and average temperature contributed the most among the three contributors (average temperature, cumulative precipitation, and cumulative sunshine hours) to isolated impacts of climate change on wheat phenology. (4) Crop management over the three decades was shown to have helped reduce the lengths of VGP and WGP, but increase the length of RGP for both spring and winter wheat, implying that shorter-duration varieties with a higher yield or better yield stability in changing climate might have been introduced by farmers.

Recently the expansion of urban-rural income inequality and the rapid growth of fossil-energy consumption have become two significant challenges China should address to achieve its ambitious goals. For the first time, this study uses the Chinese provincial panel data during the period of 1996–2013 to perform a quantitative analysis on the relationship between the urban-rural income gap and the per capita electricity consumption. Fully considering the potential endogeneity problem, this paper uses the orthogonal-difference Generalized Method of Moments (GMM) as the benchmark estimation method. To ensure the robustness of the estimations, the Theil index and per capita urban-rural income are utilized to measure the urban-rural income gap. The estimation results indicate that the influences of urban-rural income inequality on electricity depend on the income level. At the current stage of economic development, the income disparity has significantly negative impacts on provincial per capita electricity consumption. Moreover, there is also strong evidence for the existence of the inverted U-shaped relationship between per capita electricity consumption and GDP per capita. Furthermore, other economic and social factors, including the enhancement of urbanization and industrialization levels, the adjustment of the population structure, and the development of import-export trade may also promote electricity consumption.

ABSTRACT The biases in the Global Circulation Models ( GCMs) are crucial for understanding future climate changes. Currently, most bias correction methodologies suffer from the assumption that model bias is stationary. This paper provides a non-stationary bias correction model, termed residual-based bagging tree ( RBT) model, to reduce simulation biases and to quantify the contributions of single models. Specifically, the proposed model estimates the residuals between individual models and observations, and takes the differences between observations and the ensemble mean into consideration during the model training process. A case study is conducted for 10 major river basins in Mainland China during different seasons. Results show that the proposed model is capable of providing accurate and stable predictions while including the non-stationarities into the modelling framework. Significant reductions in both bias and root mean squared error are achieved with the proposed RBT model, especially for the central and western parts of China. The proposed RBT model has consistently better performance in reducing biases when compared with the raw ensemble mean, the ensemble mean with simple additive bias correction, and the single best model for different seasons. Furthermore, the contribution of each single GCM in reducing the overall bias is quantified. The single model importance varies between 3.1% and 7.2%. For different future scenarios ( RCP 2.6, RCP 4.5, and RCP 8.5), the results from RBT model suggest temperature increases of 1.44, 2.59, and 4.71 °C by the end of the century, respectively, when compared with the average temperature during 1970-1999.

Population change is a key variable that influences climate change, ecological construction, soil and water use, and economic growth. Census data are always point data, whereas planar data are often required in scientific research. By using nighttime light (NTL) images and land use data, combined with the fifth and sixth census data of China at the county level, we carried out spatial matching on the population of each county, respectively, and established population density diagrams of China for 2000 and 2010, which had a spatial resolution of 1 × 1 km. The method proposed in this paper is relatively simple and has a high simulation precision. The results showed that during the first ten years of the 21st century, there are some remarkable characteristics in Chinese population spatial pattern change: 1) the “disappearance” of intermediate-density regions; namely, areas with a population density between 500 and 1500 persons/km 2 have decreased by 41% during the ten years; 2) continuous growth of high-density regions; namely, areas with a population density of more than 1500 persons/km 2 have increased by 76%; 3) an expansion tendency of low-density regions similar to high-density regions.

This paper investigates how piloting programmes in China can promote local policy innovations. By using one of the piloting emission trading schemes (ETS) in Guangdong province as a case study, it is argued that the main features of the piloting experiments, particularly in the climate change domain, are largely different from previous local marketization experiments that dominate the reform period of China. Whereas previous experiments are often characterized as bottom-up or indigenous initiatives with strong patronage relations to the pro-reform politicians at central level, the current piloting programmes are often crafted in a top-down fashion that is often misaligned with local market or corporate interests. Hence, local policy innovations are designed, developed and brokered by the local state officers, in order to bridge this central–local interest gap. As a result, successful implementation of these policy innovations largely depends on local political traditions, bureaucratic culture and perceptions of distinctive development needs.

This paper investigates total factor carbon-sensitive productivity growth in the regional transport sector in China and decomposes its dynamic changes over time taking account of the regional heterogeneity of different provinces. Thus, the contemporaneous metafrontier Malmquist-Luenberger approach that combined with non-radial directional distance functions is proposed and define a new indicator called the contemporaneous metafrontier Malmquist-Luenberger carbon emission performance index (CMML). This total factor indicator includes the metafrontier efficiency-change index (MEC), the metafrontier technology-change index (MTC), and the metafrontier technology-gap-change index (TGC). Results show an about 4% increase in overall total factor carbon emission productivity during the period of 2000–2012. Different growth patterns are also observed in the transport sector across different area of China. In the eastern region, the growth of carbon productivity is driven mainly by pure efficiency changes, whereas the central region is driven mainly by innovations in the low-carbon transport technology.

Electric vehicles (EVs) have been regarded as one of the most prominent green technologies, touted to help reduce global energy consumption and carbon emissions. China advocates the development of EVs to address the increasing challenges of climate change, urban air pollution and energy security, but consumers’ enthusiasm for adopting EVs remains low. In this paper, we present a concept model that hypothesizes Chinese cultural values as a key to understanding Chinese consumers’ intention to adopt EVs. Based on a nationwide online survey in China, this study explores Chinese consumers’ attitudes toward two types of EVs—battery electric vehicles and plug-in hybrid electric vehicles—by identifying the influence of the human–nature relationship, long-term orientation, face consciousness, and risk attitude, as well as the mediating effect of deontological ethical evaluation in decision-making. The results suggest that public policy and social marketing efforts should pay more attention to the role of cultural values when promoting environmentally sustainable technologies, and importantly, that the promotion efforts should differ for different cultural elements and products with different levels of innovativeness.

This paper examines China's policy and position in relation to the evolving climate change negotiations in order to explain how China is dealing with the dilemma of meeting its growing development needs while reducing GHG emissions. It argues that global climate governance requires steering and leadership to deal with the interlocked political process; that the developing countries (DCS) right to develop is challenged by the need for ecosystemic standards especially as climate change is seen as a zero-sum game as the more one country emits the less another one can. This is especially problematic as Industrialized countries (ICS) appear to be both unwilling and unable to increase growth without increasing emissions. This explains China's policy of insisting on its right to develop, of demanding that ics reduce their emissions and that they fulfil their obligations under the FCCC, while expressing its willingness to take on a voluntary target. The paper argues that China's state-led transition has eight unique characteristics that may allow it to lead as it moves beyond a no-regrets policy to a circular and green economy, cooperating with other DCS and mobilizing conscious green values in citizens. The question remains--will the initial success and scale of state-led transition lead the global green transition to a sustainable world? [ABSTRACT FROM AUTHOR]

Abstract: The unprecedented resources and energy needed to support the high growth of urbanization with the emerging issues of environmental degradation and GHG emissions is increasingly dramatic in China. A series of national and local policies have been implemented for achieving the co-benefits of reducing emissions of greenhouse gas (GHG) and air pollution for China's sustainable development. In this paper, the achievement of climate change mitigation and air pollution reduction in different sectors through implementing policies is reviewed. This paper reports on the types of policy measures that have been introduced in two cases (i.e. Tiexi District of Shenyang and Baoshan District of Shanghai) to affect air quality and energy efficiency improvements, which are then collectively examined in terms of their impacts on GHG and air pollutant emissions. Recommendations are made for achieving co-benefits effectively through the integrated approach by comprehensively concentrating on the short and long-term environmental protection and energy conservation at local and national levels based on the analysis made in the paper. The limited coordination and lack of capacity in different government bodies may be the main barriers to the implementation of a co-benefits approach. Enhancing the cooperation and capacity building could overcome these obstacles. [Copyright &y& Elsevier]

China has experienced noticeable changes in climate over the past 100 years and the potential impact climate change has on transmission of mosquito-borne infectious diseases poses a risk to Chinese populations. The aims of this paper are to summarize what is known about the impact of climate change on the incidence and prevalence of malaria, dengue fever and Japanese encephalitis in China and to provide important information and direction for adaptation policy making. Fifty-five papers met the inclusion criteria for this study. Examination of these studies indicates that variability in temperature, precipitation, wind, and extreme weather events is linked to transmission of mosquito-borne diseases in some regions of China. However, study findings are inconsistent across geographical locations and this requires strengthening current evidence for timely development of adaptive options. After synthesis of available information we make several key adaptation recommendations including: improving current surveillance and monitoring systems; concentrating adaptation strategies and policies on vulnerable communities; strengthening adaptive capacity of public health systems; developing multidisciplinary approaches sustained by an new mechanism of inter-sectional coordination; and increasing awareness and mobilization of the general public.

CLIMATE change , *ENVIRONMENTAL policy - Abstract
This study examines the making of local climate governance in the Chinese setting where central-local inter-governmental relations continue to play critical part in almost every policy domain. Through analysing the climate responses of the three provincial-level governments at the Yangtze River Delta (YRD), the paper argues that the process of “experimentation under hierarchy” is relevant to understanding the evolving of the subnational climate regime in the YRD region. We find the preponderance of the central authorities in initiating national climate strategies and galvanising responses at the local level. Meanwhile, provincial governments have been able to leverage climate plans and actions to achieve their own gains. These findings suggest that any optimism about subnational climate activism in a Chinese setting has to be mixed with caution. In fact, the shadow of hierarchical authority structure lingers and plays important part in the initiation of subnational response and spurring climate responses and innovations from below.

Accurately understanding the real situation of China’s carbon emissions at the provincial level is not only crucial for realizing carbon mitigation in China, but also of great importance for tackling climate change on a global scale. This paper uses detailed energy consumption data subdivided within each fuel type and sector-specific emission factors, to calculate both direct and indirect energy-related CO 2 emissions for China’s provinces, and offers provincially-targeted policy proposals on emission reductions. The results uncover large divergences in calculation of provincial CO 2 emissions between production-based and consumption-based accounting approaches. Considering the large amount of interprovincial CO 2 emission transfers embodied in secondary energy deployment, the consumption-based accounting performs better in reflecting the actual features and responsibilities of carbon emissions in the provinces of China. From the consumption perspective, Shandong, Hebei, Jiangsu, Inner Mongolia, Guangdong, Henan, Liaoning and Shanxi contributed to the majority of China’s carbon emission growth during the period of 1996–2013, while Xinjiang, Sichuan, Anhui, Tianjin and Hunan were playing an increasingly important role. These two groups of provinces should be regarded as the key regions for national emissions abatement. Meanwhile, the energy industry was the top sectoral contributor to CO 2 emissions growth in most provinces, while service and household sectors made increasingly significant impacts on driving up provincial emissions. Together with ongoing efforts in the energy sector, the mitigation of CO 2 emissions in service and household sectors deserves much more attention, especially in the transportation and urban household sectors. Furthermore, the temporal trends of carbon emissions in various provinces, as well as their factor and sectoral driving forces, varied greatly with each other. Therefore, each of the provinces should formulate emission reduction policies according to their own situation, and target the key driving factors and sectors of carbon emissions at the current stage or in the near future.

PHASE change materials , *LATENT heat , *HEAT storage , *ENERGY consumption , *CLIMATE change - Abstract
Latent heat thermal energy storage technologies based on phase change materials (PCMs) are found to be significantly efficient and viable methods for thermal energy storage. These energy storage techniques have been proved to be with positive effects on buildings energy efficiency. The integration of appropriate thermal energy storage system and selection of suitable PCMs plays a very dominating role in the upgrading of energy efficiency. Short and long term storage helps in the reduction of energy demand or shifting peak load for both heating and cooling. However, a comprehensive study for the application of these technologies adopting Chinese built environment is lacking which can relate to climate, energy storage and energy efficiency. The goal of this paper is to provide coherent picture of current status on PCM-based techniques that have been studied with the focus of application in China and analyse the selection and suitability of PCMs and techniques in Chinese regions. The results show that many PCMs and techniques are promising to be used in China however studies can be conducted with the consideration of changing climate rather than winter/summer only.

Climate change shifts the distributions of a set of climatic variables, including temperature, precipitation, humidity, wind speed, sunshine duration, and evaporation. This paper explores the importance of those additional climatic variables other than temperature and precipitation. Using the county-level agricultural data from 1980 to 2010 in China, we find that those additional climatic variables, especially humidity and wind speed, are critical for crop growth. Therefore, omitting those variables is likely to bias the predicted impacts of climate change on crop yields. In particular, omitting humidity tends to overpredict the cost of climate change on crop yields, while ignoring wind speed is likely to underpredict the effect. Our preferred specification indicates that climate change is likely to decrease the yields of rice, wheat, and corn in China by 36.25%, 18.26%, and 45.10%, respectively, by the end of this century.
