The Permian–Triassic climate crisis can provide key insights into the potential impact of horizon threats to modern-day biodiversity. This crisis coincides with the same extensive environmental changes that threaten modern marine ecosystems (i.e., thermal stress, deoxygenation and ocean acidification), but the primary drivers of extinction are currently unknown. To understand which factors caused extinctions, we conducted a data analysis to quantify the relationship (anomalies, state-shifts and trends) between geochemical proxies and the fossil record at the most intensively studied locality for this event, the Meishan section, China. We found that δ18Oapatite (paleotemperature proxy) and δ114/110Cd (primary productivity proxy) best explain changes in species diversity and species composition in Meishan’s paleoequatorial setting. These findings suggest that the physiological stresses induced by ocean warming and nutrient availability played a predominant role in driving equatorial marine extinctions during the Permian–Triassic event. This research enhances our understanding of the interplay between environmental changes and extinction dynamics during a past climate crisis, presenting an outlook for extinction threats in the worst-case “Shared Socioeconomic Pathways (SSP5–8.5)” scenario.

Sustainable finance is often discussed as a solution to the climate crisis, but its impacts are limited and its discourse focuses on mobilising private investments through public de-risking, without considering direct government action. We argue that this is due to an implicit reference to mainstream economic theory assuming that an active state leads to time inconsistency problems and crowding-out effects. However, these assumptions have been sufficiently refuted as public investments may actually crowd-in private capital. We therefore propose a paradigm shift towards what we call Public Sustainable Finance, aimed at empowering the role of the state in the green transition on the discursive, policy, and political economy levels. Studying the case of Germany, we show how Public Sustainable Finance can be introduced despite tight fiscal regimes. To this end, we propose that the Climate- and Transformation Fund be given its own borrowing powers. By borrowing an average of 23 billion euros annually from 2024 to 2030, the existing financing gap that has been exacerbated following the November 2023 constitutional court ruling can be closed, enabling a more rapid and effective green transition.

The article discusses five literature strands’ approaches towards social protection systems in the context of climate crisis: Adaptive Social Protection, Just Transition, Green New Deal, Post-growth, and Eco-feminism. As we argue, these five strands are located on a spectrum between a green growth orientation and a green anti-capitalist orientation. Furthermore, they differ in terms of their problematisation of the climate crisis and have different perspectives on relevant actors, on world regions, and – most relevant in the context of social welfare – their conceptualisation of social protection. While Adaptive Social Protection emphasizes cash transfers and insurances, Green New Deal and Just Transition approaches focus more on redistribution and labour market policies, and Post-growth and Eco-feminist approaches more on universalist policies and systems. We argue that these literatures each have their weaknesses, but also offer urgent questions, concepts, and insights for further social policy research.

Climate change is arguably the defining issue of our time, with global impacts. Yet to date, scholarship within social policy has remained relatively fragmented and disparate, leaving an urgent need to start comprehensively embedding environmental thinking across all domains of the discipline (Williams, 2021). Responding to this challenge, this paper draws together existing work at the nexus of social policy, the environment, and climate change. The paper then presents findings from workshops held with social policy scholars, policymakers, and practitioners, using these discussions to propose pathways to embed climate change within the discipline. The paper represents a significant contribution to knowledge within the field as it seeks to both broaden discussions about social policy and climate change; to identify theoretical and empirical relationships that exist between the two fields but have not been fully recognised in existing scholarship; and to bring new perspectives and voices into the discussion.

This article considers the fiftieth anniversary of the 1972 United Nations Educational, Scientific and Cultural Organization’s (UNESCO) World Heritage Convention in light of climate change, offering a state of the field review of climate responses for World Heritage sites (WHS). Opening with a brief review of UNESCO World Heritage activities around climate change, we then detail the primary impacts and risks that climate change pose for WHS and the reporting and monitoring systems in place to document and track these impacts. Looking forward, we examine the most promising pathways for World Heritage to advance in the domains of climate mitigation, adaptation, climate communication, and climate action.

In this editorial, we consider the ways in which liberal constitutionalism is challenged by and presents challenges to the climate crisis facing the world. Over recent decades, efforts to mitigate the climate crisis have generated a new set of norms for states and non-state actors, including regulatory norms (emission standards, carbon regulations), organising principles (common but differentiated responsibility) and fundamental norms (climate justice, intergenerational rights, human rights). However, like all norms, these remain contested. Particularly in light of their global reach, their specific behavioural implications and interpretations and the related obligations to act remain debatable and the overwhelming institutionalization of the neoliberal market economy makes clear and effective responses to climate change virtually impossible within liberal societies.

The Anthropocene rupture refers to the beginning of our current geological epoch in which humans constitute a collective geological force that alters the trajectory of the Earth system. An increased engagement with this notion of a rupture has prompted a lively debate on the inherent anthropocentrism of International Relations (IR), and whether it is possible to transform it into something new that embraces diverse forms of existence, human as well as non-human. This article challenges that possibility. It shows how much of the current debate rests on the idea fulfilling future desirable ideals, which are pushed perpetually beyond a horizon of human thought, making them unreachable. As an alternative, the article turns to Jacques Derrida's understanding of the future to come (l'avenir), highlighting the significance of unpredictability and unexpected events. This understanding of the future shows how life within and of the international rests on encounters with the future as something radically other. On this basis, it is argued that responding to our current predicament should proceed not by seeking to fulfil future ideals but by encountering the future as incalculable and other, whose arrival represents an opportunity as much as a threat to established forms of international life.

The environment remains on the margins of social policy. Bringing degrowth literature into conversation with social policy debates about decommodification, we argue that a re-imagined decommodification remains central to addressing the social-ecological challenges we face and to forging a post-growth, post-productivist ecosocial welfare state. We explore the implications of this for re-imagining and mapping three core areas of an ecosocial welfare state revolving around the work/welfare/care nexus: the redistribution of time across work and care; repurposing of active labour market measures; and reorienting cash transfers and services. In each case we discuss what decommodified social policy in the service of a post-growth, post-productivist future might entail. Acknowledging challenges, we identify how instances of prefiguration of policy programmes and experiments across various countries offer concrete compass points for further transformation and a necessary paradigmatic shift.

In May 2021, at Pentecost, a joint Pastoral letter was issued by the Catholic Bishops Conferences of England and Wales and of Scotland. This letter linked the feast day to the urgent need to care better for creation in the months leading to the G20 summit later in the summer and the COP-26 conference in Glasgow in November of that year. This paper looks at the letter, taking some account of reactions to it, and begins to explore ways in which our theology of the Holy Spirit can inform our theology of care for the created order as a developing part of Catholic Social Teaching. Some ‘footprints’ of the Spirit: First, the witness of patristic theologians encourages us to see rationality pointing to order in creation as a fruit of the Spirit. Second, the picture of unity in diversity formed by the Spirit in the New Testament points to the need for cooperation in our response to the current crisis. The last footprint is urgency: in the scriptures the Spirit's activity is constantly seen as urgent, sometimes in an extreme way. This picture suits the urgency of the current crisis in relation to climate change and biodiversity.

Two school strikers − Niamh and Harriet − come together with two environmental education academics − Peta and Joseph − to explore what it means to be young people enacting politics for the environment in Australia, and what this might mean for re-imagining education. Niamh and Harriet are leaders of, and were integral to initiating, the highly effective School Strike 4 Climate − Australia (SS4C) movement, enacting ‘principled disobedience’. Peta and Joseph work in teacher education, preparing future teachers who will teach students who are increasingly climate savvy and politically active. In coming together and through the lens of pragmatism, we highlight the political nature of what Niamh and Harriet have been undertaking as they negotiate social, cultural, educational and environmental issues implicated in the climate crisis. Collaborative autoethnography framed our exploration of motivations for action, politics and education within our communities. Through Niamh’s and Harriet’s experiences, we explore how young people express agency while developing identity. Our autoethnographic conversations highlighted the experience and political agency that many of our young people demonstrate and led to us reflecting on the resulting opportunity for educators to ‘dare to think’ differently about education.
