Nature-based solutions (NbSs) are increasingly recognised for their potential to address climate change and biodiversity loss, but their role in mitigating antimicrobial resistance (AMR) remains underexplored. AMR and climate change share environmental drivers, such as pollution, ecosystem degradation, and industrial agriculture, yet responses often remain fragmented and technocratic. This paper draws on a global roundtable series convened under the British Academy’s “Just Transitions for AMR” initiative to explore how NbS can support more just, equitable, and integrated responses to these intersecting crises. Bringing together 46 experts from public health, environmental science, agriculture, governance, and social sciences, the roundtables facilitated interdisciplinary exchange across Africa, Asia, and Europe. The paper synthesises insights across four thematic areas: conceptualising Just Transitions in NbS, identifying co-benefits for scaling NbS for climate and AMR mitigation, addressing implementation barriers, and proposing future directions. Findings emphasise the need to reframe NbS as socially embedded practices co-designed with communities, rather than as technical fixes. Participants called for investment in place-based approaches, participatory monitoring, and governance structures promoting inclusion. The paper concludes by aligning NbS with One Health and Just Transition principles, urging a shift from isolated interventions to systems-oriented transformations that redress power imbalances in environmental and health governance.

To anticipate relationships between future climate change and societal violence, we need theory to establish causal links and case studies to estimate interactions between driving forces. Here, we couple evolutionary ecology with a machine-learning statistical approach to investigate the long-term effects of climate change, population growth, and inequality on intergroup conflict among farmers in the North American Southwest. Through field investigations, we generate a new archaeological dataset of farming settlements in the Bears Ears National Monument spanning 1,300 years (0 to AD 1300) to evaluate the direct and interactive effects of precipitation, temperature, climate shocks, demography, and wealth inequality on habitation site defensibility—our proxy for intergroup conflict. We find that conflict peaked during dry, warm intervals when population density and inequality were highest. Results support our theoretical predictions and suggest cascading effects, whereby xeric conditions favored population aggregation into an increasingly small, heterogenous area, which increased resource stress and inequality and promoted intergroup conflict over limited productive patches. This dynamic likely initiated feedback loops, whereby conflict exacerbated shortfalls and fostered mistrust, which drove further aggregation and competition. Results reveal complex interactions among socioclimatological conditions, all of which may have contributed to regional depopulation during the thirteenth century AD.

The population status of Adélie penguins (Pygoscelis adeliae) on the Antarctic Peninsula highlights opportunities for the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to address uncertainty more directly and effectively in its conservation efforts. The heightened uncertainty posed by climate change is testing CCAMLR’s commitment to balancing science and international cooperation in decision-making. Uncertainty underpins some of the justification to postpone reaching a consensus on the establishment of Marine Protected Areas, leaving Adélie penguins vulnerable to change. Two key opportunities to adapt current management approaches emerge: 1) reduce uncertainty by systematically identifying knowledge gaps within CCAMLR’s processes; and 2) integrate uncertainty more explicitly into decisions through a standardized approach to assessing and communicating it.

We describe the main insights from the papers included in this special issue, Challenges for the Development of Latin America in the Anthropocene: Current Research in Environmental Economics. The contributions are organized around three themes: the economic and welfare impacts of temperature variability, the role of institutions and user rights in shaping environmental governance and the effectiveness of regulatory instruments for managing ambient and atmospheric pollution. Together, these papers show that environmental outcomes in Latin America are deeply shaped by institutional capacity, governance quality and social inequality. By combining rigorous empirical analysis with attention to local contexts, they demonstrate how environmental economics can inform policy responses to the triple planetary crisis of climate change, biodiversity loss and pollution.

Despite repeated calls for action from various sources, peatland archaeological sites continue to deteriorate; the passive strategy of preservation in situ is failing. Here, the authors consider four challenges to peatland preservation—physical degradation, mapping and monitoring of sites, communication, and policy frameworks—with climate change ultimately causing further problems. Drawing on positive policy developments in England, they argue that advocacy for peatland archaeology needs to be louder and clearer: archaeology must become an integral consideration in all climate-change mitigation and land-use planning, rather than an afterthought, if the fragile heritage of European peatlands is to be preserved.

This study presents three key steps to enable the Business and Human Rights (BHR) research agenda to promote and advance greater applicability to the emerging challenges in the field. Drawing on research conducted on BHR sources (almost exclusively by Brazilian and Spanish-speaking authors), this article aims to demonstrate the need for further BHR scholarship to simultaneously: (i) identify and remedy epistemic biases through reflexive engagement with a victim-centred scholarship from the Global South that recentres BHR research on the perspective of affected communities; (ii) move from consideration to co-production by grounding BHR theory in practice via participatory methodologies and dialogue between communities, researchers and corporations; and (iii) by aligning with steps one and two, recontextualize Human Rights Due Diligence (HRDD) research into an integrated Human Rights and Environmental Due Diligence (HREDD) approach that incorporates environmental and climate dimensions and ensure meaningful, victim-centred engagement with affected communities.

The second Trump administration has disrupted global climate politics, turning the United States away from the clean energy and environmental policies of the Biden administration. Consequently, analytical attention is turning, inside and outside of the United States, to a family of concepts referred to as “Climate Realism” (CR), which favors long-run investments in technology and adaptation over near-term climate mitigation efforts. We critically engage with CR and argue that political science identifies four key features of climate politics that shed light on CR’s strengths and weaknesses, and which will persist even in the second Trump era. Despite CR’s flaws, we contend that its emergence in reaction to the second Trump administration highlights some important dimensions of climate politics that deserve greater attention going forward. We highlight three topics for research: the political and practical strategies of the anti-green coalition; the heterogeneity in viable national economic strategies; and the implications for IR of a turn away from meaningful climate mitigation in powerful nations.

Strategic litigation has emerged as a prominent tool in the business and human rights (BHR) field, offering a pathway to promote corporate accountability, test innovative legal arguments and push for systemic change. While often framed as private tort actions, such litigation frequently aims to shape broader norms beyond individual remedies. This article explores how strategic litigation contributes to the evolution of corporate responsibility to respect human rights by analysing two case studies: supply chain liability claims in English courts and corporate climate litigation in the Netherlands. Drawing on these examples, the article argues that, despite its limitations, strategic BHR litigation plays an important role in translating soft law standards, including the UN Guiding Principles on Business and Human Rights, into enforceable legal duties.

This essay argues for an integrative move in the investigation of the politics of ‘green’ finance. We suggest that approaching the politics of ‘green’ finance in the form of knowledge contestations can bring out complementarities and bridge divides between different levels of analysis and theoretical traditions. Our focus is motivated by the pivotal role of knowledge and ignorance in the organisation and governance of financial markets identified in economic sociology, political economy, and neighbouring disciplines. Drawing on this scholarship, we consider knowledge both a forum for and a means of politics. We then illustrate how this conceptualisation provides insights into the politics of ‘green’ finance on different levels of analysis and following different theoretical traditions: in the context of tracing elites in their dissemination of specific ideas shaping governance regimes; when following market devices which produce partial calculative representations of the world; in problematising how financial organisations both produce and accept certain types of knowledge to further their interests; and when examining the role of ideology and imaginative capture in stabilising financial capitalism during climate crisis. We conclude by identifying the connective tissue between these different analytical and theoretical approaches made visible by the integrative concept of politics as knowledge contestations.

In 1988, meteorological measurements started at the Spanish research station Juan Carlos I (JCI) on Livingston Island. A second station - Gabriel de Castilla (GdC) - was installed in 2005 on Deception Island. These long-term measurements improved our climatological understanding of the western region of the South Shetland Islands (SSI), a region that has received less attention than the more station-populated King George Island in the central SSI. Here, we present a complete climatological analysis of these stations after undertaking a full quality control process of the data. This analysis covers temperature, wind, precipitation, radiation, relative humidity and pressure, as well as trends and variability. The results show: 1) the stations along the western SSI coastline, particularly JCI, are warmer than those on the central SSI, especially in summer, 2) at GdC, winters are colder due to stagnant cold air pooling within the Deception Island caldera, 3) the importance of island orography in shaping local climatology, especially regarding wind patterns, and 4) the critical need to correct precipitation measurements for undercatchment of solid precipitation by common pluviometers. This study provides a climatological framework to support further research conducted in the region.
