However, conventional evaluations of tourism climate suitability have consistently relied on uniform indicators. In reality, the combination of meteorological factors that tourists are sensitive to and the threshold ranges for their comfort vary across different climate zones. This study, for the first time, utilizes a dataset of 2,326,954 tourist behaviors in hiking to validate the differences in sensitivity to meteorological conditions among tourists in different climate zones and to assess the historical and future tourism suitability in various climate zones. The findings reveal the following key results: (1) The sensitivity of hiking activities to meteorological factors varies among tourists in different climate zones. For instance, tourists in the mid-subtropics and south temperate zones show a lesser sensitivity to precipitation, while those in the southern subtropics are less affected by temperature fluctuations. Tourists in plateau climate zones appear to be insensitive to both precipitation and average relative humidity. (2) Significant differences exist in the climate comfort ranges for tourists from different climatic regions when engaging in hiking activities. Tourists in the mid-subtropics exhibit the highest tolerance for daily maximum temperatures during hiking, whereas those in arid and semiarid regions have a greater comfort threshold for average relative humidity compared to individuals in humid and subhumid regions. (3) Over the past decade, the southern subtropics experienced the highest number of days suitable for hiking among tourists, while the plateau climate zone recorded the fewest. The frequency of comfortable hiking days per year (CDY) increased for tourists in the north subtropics, mid-subtropics, southern subtropics, and plateau climate zones but declined for tourists in the mid-temperate and south temperate zones. (4) Looking ahead to the future, climate conditions conducive to hiking for tourists in different climate zones are generally trending towards deterioration. By the year 2080, both the mid-subtropics and south temperate zones are projected to have the fewest CDY. While the southern subtropics may still have the most CDY for tourists’ hiking, it is anticipated to experience the most rapid decrease.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141541306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a first exploratory model (<em>N</em> = 967), followed by a direct, pre-registered replication (<em>N</em> = 953), we examine how two facets of temporal orientation – consideration of <em>future</em> and <em>immediate</em> consequences – predict intentions to engage in three kinds of climate action at individual and collective levels: conventional private-sphere, conventional public-sphere, and radical public-sphere climate action. Consistent with past research, higher consideration of future consequences and lower consideration of immediate consequences are associated with intentions to take conventional action directly and indirectly via eco-anxiety and/or access to environmental cognitive alternatives. In contrast, consideration of future and immediate consequences are only indirectly related to intentions to take radical action.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0959378024000906/pdfft?md5=ea9ae8fb70c07d00dced17f189457231&pid=1-s2.0-S0959378024000906-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141541307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little research exists on how groups affected by renewable energy siting interpret and mobilise justice narratives to legitimise their actions and question development plans. Building on the notion of 'framing' in social movement theory, this study addresses this gap by examininig the discourses adopted by people resisting wind energy developments in the Isthmus of Tehuantepec, Mexico. The study relies on 64 interviews and participant observation. The findings indicate that anti-wind activists used health and environmental concerns instrumentally: as a framing device to avoid social rejection and legitimise other, subtler distributive concerns about the uneven allocation of economic benefits such as tenancy payments. Although this framing was counterproductive and left their concerns unaddressed, activists adopted this strategy because of community norms and practises that stigmatise the explicit discussion of economic inequalities and their fear of challenging existing power structures. This paper therefore highlights the social mechanisms through which energy transitions reproduce economic inequalities. As a policy recommendation, it is critical to consider how inequalities are framed and the underlying reasons for these interpretive schemes to advance socially just net-zero scenarios.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0959378024000876/pdfft?md5=876e069a0cba5455583a36b2f734631a&pid=1-s2.0-S0959378024000876-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through mechanism analysis, reasonable expansion of urban pipelines and WWTPs, promotion of biofilm treatment technology, reduction of energy consumption, and improvement of pollutant reduction efficiency are feasible paths to improve water quality and reduce carbon emissions.

We note that the field is diverse in terms of contributions from geographers, sociologists, anthropologists, and public policy scholars. The research to date has been concerned with the ways in which the deployment of desalting techniques can reflect and reinforce social processes of inequality, political power and economic flows. In this way, desalination has been opened up for intellectual debate beyond technical considerations of the desalting industry and engineers. A critical perspective that complements the recent discussions of environmental harm caused by the desalination industry has emerged as well across a number of global and transboundary contexts. A number of themes emerged that will continue to be of interest to scholars and that need to be addressed in the years ahead. First, desalination intersects transboundary water governance and geopolitics between different water uses and emerges from complex assemblages of local and global actors, including financial actors, water companies, governments, technologies, and natural forces. Second, critical scholarship on desalination needs to continue to pay attention to the interests in and overarching patterns of, the Green New Deal and Blue Economy, each of which intersect with the worlds of academia and policymaking, and involve issues of climate adaptation and mitigation. Third, questions about equity remain with desalination as it is a solution deeply imbricated in the unequal distribution of resources, and questions about representation in decision-making remain. Fourth, research on finance and infrastructure have been at the core of critical desalting research and should remain so. Fifth, there is a growing heterogeneity in terms of research in types of desalting, from reverse osmosis to inland desalting to nuclear and more. This variety will make for rich research for the years ahead. Our hope is that the epistemological, theoretical, and methodological flexibility of this area of research will remain a strong point continuing its rigor, as well as the already robust collegiality among scholars in this interesting, and still nascent field.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":null,"pages":null},"PeriodicalIF":8.9,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141424408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we seek to identify current narratives of migrants and sustainability across individual, urban, and national scales. Migrants are commonly framed in public policy as having no or even negative impacts on sustainability. The study hypotheses that the lived experience of sustainability by migrants within urban destinations differ from dominant discourses and perceptions of migrant populations within societies. We test and document such divergence using data from 21 interviews with key stakeholders from the city and Swedish national level, an attitudinal survey of 895 migrants and non-migrants in Malmö, Sweden; and a media analysis of local and national Swedish newspapers. Survey results show that migrants engage more extensively with a number of sustainability actions compared to non-migrants culminating in new insights on ‘migrants as sustainability actors’. By contrasting individual scale practices against urban to national sustainability narratives, the study illuminates current barriers to and the potential of migrants to play a transformative role in progress towards sustainability that is unrecognized in dominant policy discourses.
