This paper studies both regions through a thematic analysis of problem-centered expert interviews with local stakeholders. It provides a comprehensive assessment of pathways from environmental change to human insecurity in both regions. Climate change impacts are omnipresent in Vanuatu and coproduced by fast lifestyle change and developmental challenges. In contrast, Guam is a highly developed US territory. This reduces climate vulnerability but generates other forms of environmental change from heavy military and touristic use. The article argues that human insecurity on Vanuatu and Guam is coproduced by the interplay between economic and (post-)colonial factors and environmental change. This demonstrates that vulnerability and environmental degradation are by no means natural or inevitable, but strongly shaped by socio-economic contexts and histories. This builds an important bridge between human security, political economy, and postcolonial perspectives on environmental security.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"89 ","pages":"Article 102935"},"PeriodicalIF":8.6,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0959378024001390/pdfft?md5=1a4c8252f405c222310a7edfa57846c1&pid=1-s2.0-S0959378024001390-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142315753","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}

The emerging field sees growing insights about characteristics and mechanisms of social system tipping; however, much disagreement remains. This includes whether social tipping points can be anticipated – determining its political relevance, as anticipation is essential for actions to intentionally trigger tipping. We address this disagreement and propose a framework which operationalises socio-technical tipping across subsystems and elements to anticipate tipping points, illustrated in two case comparisons. We show that whereas the transition to electric cars in Germany has started but is not about to tip, especially not regarding normative and regulatory regime factors, the same transition in Norway is about to tip, but still requires international car markets to tip before the sectoral transition is tipped and complete. Similarly, we show that the transition to a PV-based renewable power system in Germany has progressed strongly, both regarding technology and regime factors, but the system has not yet tipped: further efforts reforming infrastructure and regulation are essential. Hence, our findings emphasise the notion that while technological progress holds significance, it represents only one facet among several that must align for a system to undergo a tipping point.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"89 ","pages":"Article 102911"},"PeriodicalIF":8.6,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0959378024001158/pdfft?md5=db8b37031a83d280eb85c501fb0f645d&pid=1-s2.0-S0959378024001158-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142272119","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}

Our research objectives are twofold: firstly, to determine the extent to which climate contrarians gained access to testify at congressional hearings in the years leading up to the bill’s ultimate defeat; and secondly, to examine the potential influence of fossil fuel industry (FFI) funds in facilitating this access. We compile a comprehensive new dataset encompassing all witnesses testifying at cap-and-trade and climate science hearings from 2003 to 2010. This information is cross-referenced with other pertinent data concerning interest groups, lobbying activities, and Congress. Our findings reveal a significant correlation between FFI lobbying expenditures and campaign contributions and the presence of contrarian witnesses at these hearings, suggesting a coordinated effort by the FFI to obstruct climate legislation. We find that contrarians were able to obtain disproportionate access to central hearings in key committees with jurisdiction over cap-and-trade bills, increasing their potential to obstruct legislation.

Here, we model the spatial diffusion of human induced regeneration projects in Australia between 2014 and 2022 using spatiotemporal data on project registrations and spatial data on the methodology’s economic feasibility. We find that spatial proximity to existing projects is a strong predictor of landholder adoption, conditional on the methodology’s average economic feasibility in the region. We also find that a region’s average economic feasibility is a relatively weak predictor of adoption, after accounting for landholder proximity to existing projects. The spatial dependency of the diffusion process has led to high levels of spatial concentration in Australia’s carbon supply, raising concerns regarding land use efficiency and carbon supply risk.

Since the 1990s, the number of floating objects in the open ocean has increased greatly as a result of the introduction of drifting fish aggregating devices (DFADs) by the industrial tropical tuna purse seine vessels. These changes, and their potential impacts on the species that associate with floating objects, remain poorly understood. If the habitat modifications induced by DFADs have been recently characterized and quantified, the impact of other human activities on the number of floating objects is poorly studied. Relying on lagrangian simulations at the scale of the whole Indian Ocean, from 2000 to 2019, we assess the potential modifications of the pelagic surface habitat that could originate from forest cover change and climate variations. We develop several scenarios, based on coastal and river forest cover, precipitations and river discharge, to simulate densities of NLOGs. Our results suggest no significant increase in average NLOG densities in the ocean and highlight important regional and seasonal variations of these densities driven by both forest cover change and precipitations. These preliminary findings underscore the limited understanding of this critical element of pelagic species habitat. Therefore, there is pressing need to intensify monitoring efforts for pelagic species habitat and raise awareness about potential impacts of habitat modifications on tuna and other pelagic species.</p></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"88 ","pages":"Article 102917"},"PeriodicalIF":8.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0959378024001213/pdfft?md5=4c6ea8b227193921e5fd8adafffcf302&pid=1-s2.0-S0959378024001213-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142138076","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}
