Within the extensive scientific and policy discussions about climate change migrants, detailed analyses continue to highlight the lack of evidence thus far for climate change directly causing migration. To understand better how climate change might or might not lead to migration, this paper explores possibilities for developing a robust, repeatable, and verifiable method to count or calculate the number of people migrating or not migrating due to climate change. The discussion starts by examining definitions of “climate change” and “migration”, then looking at how to determine numbers of climate change migrants based on those definitions. These points lead to descriptions of the subjectivity and arbitrariness of the decisions needed for counting or calculating climate change migrants and non-migrants. While the scientific study of working out numbers of climate change migrants and non-migrants is challenging and interesting, especially due to its complexity, changing baselines alongside legitimate concerns about necessary assumptions lead to questions regarding the usefulness of the calculations for policy and action. Ultimately, labelling, counting, and calculating climate change migrants and non-migrants depend on political choices, so any numbers reached might not be scientifically robust. Improved understanding of people’s motivations for migrating and not migrating under different circumstances, including under climate change and perceptions thereof, would be preferable to a starting point assuming that climate change inevitably causes migration.

In the dominant “climate change” imaginary, this phenomenon is distant and abstracted from our experiences of weather and the environment in the privileged West. Moreover, climate change discourse is saturated mostly in either neoliberal progress narratives of controlling the future or sustainability narratives of saving the past. Both largely obfuscate our implication therein. This paper proposes a different climate change imaginary. We draw on feminist new materialist theories—in particular those of Stacy Alaimo, Claire Colebrook, and Karen Barad—to describe our relationship to climate change as one of “weathering.” We propose the temporal frame of “thick time”—a transcorporeal stretching between present, future, and past—in order to reimagine our bodies as archives of climate and as making future climates possible. In doing so, we can rethink the temporal narratives of climate change discourse and develop a feminist ethos of responsivity toward climatic phenomena. This project reminds us that we are not masters of the climate, nor are we just spatially “in” it. As weather‐bodies, we are thick with climatic intra‐actions; we are makers of climate‐time. Together we are weathering the world.

In the field of climate change adaptation, the future matters. River futures influence the way adaptation projects are implemented in rivers. In this paper, we challenge the ways in which dominant paradigms and expert claims monopolise the truth concerning policies and designs of river futures, thereby sidelining and delegitimising alternative river futures. So far, limited work has been performed on the power of river futures in the context of climate change adaptation. We conceptualised the power of river futures through river imaginaries, i.e., collectively performed and publicly envisioned reproductions of riverine socionatures mobilised through truth claims of social life and order. Using the Border Meuse project as a case study, a climate change adaptation project in a stretch of the river Meuse in the south of the Netherlands, and a proclaimed success story of climate adaptation in Dutch water management, we elucidated how three river imaginaries (a modern river imaginary, a market-driven imaginary, and an eco-centric river imaginary) merged into an eco-modern river imaginary. Importantly, not only did the river futures merge, but their aligned truth regimes also merged. Thus, we argue that George Orwell’s famous quote, “who controls the past, controls the future: who controls the present, controls the past” can be extended to “who controls the future, controls how we see and act in the present, and how we rediscover the past”.

Generational tensions are often invoked in discussions about climate change, framing the crisis as a failure of older generations to safeguard the future of younger and upcoming ones. While this rhetoric can mobilize youth, it risks overshadowing deeper structural inequalities—such as economic, racial, and geopolitical disparities—that shape both accountability for and vulnerability to climate change. An intergenerational climate imaginary, built on solidarity and intersectionality, offers a more unifying and effective framework for addressing the crisis and fostering collective action. This article explores the possibilities and limitations of such an imaginary by analyzing Jan Terlouw’s children’s book Het hebzuchtgas. The story presents a vision of intergenerational collaboration, where younger and older characters work together to confront environmental collapse, emphasizing the value of long-term thinking over short-term profit motives. However, the narrative also exhibits significant shortcomings, including problematic colonial and heteronormative tropes and an underdeveloped portrayal of youth emotions. We argue that a robust intergenerational climate imaginary must integrate insights from intersectionality, decoloniality, queer theory, and affect studies to produce more inclusive and transformative narratives. Through a critical reading of Het hebzuchtgas, this article offers pathways for reimagining intergenerational solidarity in climate activism.

This article offers an exploratory quantitative analysis of the conceptual career of climate in US English over the period 1800–2010. Our aim is to qualify two, closely related arguments circulating in Environmental Humanities scholarship regarding the concept’s history, namely that we only started to think of climate as a global entity aft er the introduction of general circulation models during the final quarter of the twentieth century, and, second, that climatic change only became an issue of environmental concern once scientists began to approach climate as a global model. While we do not dispute that the computer revolution resulted in a significantly new understanding of climate, our analysis points to a longer process of singularization and growing abstraction starting in the early nineteenth century that might help to nuance and deepen insights developed in environmental history.

The Anthropocene event erupts, causing a series of changes in the onto-epistemological categories from which our discussions about the nature of visual and sound images have hitherto been based. Herewe present the first steps of a collective research program on the narratives of/in the Anthropocene. Initially conceived as a written version of the work produced to be presented at aconference, this essayreportson Gaia's intrusion into that same presentation. At first, we investigate the audiovisual narrative about climate change, but the experience of the floods in Rio Grande do Sul in 2024 went beyond the practices of everyday academic life, damaging the intended production of meaning and bringing out aspects of the imaginary at play in climate change.

Abstract The environment and climate change have achieved global, imaginary and institutional, centrality. Yet, despite efforts by social movements and intellectuals to change the status of ‘nature’ in social life, its unsurpassable exteriority in relation to ‘society’ remains a defining feature of modernity. While the imaginary is to a large extent fluid, these are core elements that hardly change, and by the same token are hard to change, one of the reasons being that they are crystalized in institutions, which contributes to their recursiveness and reiteration. This article explores the reasons for this, reconstructing the modern perspective, the role of subjectivity in it and some alternative views while focusing on the political dimension of modernity. It then goes on to tackle contemporary issues. If we aim to bring about a different world, and this does not exclude recourse to different civilizational alternatives, I argue that it is mostly from within the modern imaginary and institutional framework that we must face up to present challenges. I also suggest that the concepts of collective subjectivity and materiality may contribute to a renewed understanding of these questions within a critical theory perspective.

From 2011’s Occupy movements to the Umbrella Movement Hong Kong to the recent Climate March in September 2019, typified by Extinction Rebellion’s performative acts of resistance, there’s been an exponential increase in protests around the world. People move together en masse to challenge economic inequality and political ineptitude; they demand racial justice and action against climate change and Indigenous land rights. Ideally, protests and forms of direct action generate new ideas where the use of bodies in space become conduits to spark debate, bring awareness, with the hope to change the discourse about urgent issues. The visual power of many bodies speaking both to each other and to a larger public offers a space everyone can safely participate in the social imaginary. This paper considers Extinction Rebellion's graphic and performative aesthetics.

In this essay, I suggest that we are currently witnessing a mutation, which disrupts the mythical imaginary that had confined viruses, climate change, and atmospheric turbulences to an immutable background in the all-too-human narrative of the struggle against nature. I argue that the incapacity of translating this mutation in cultural and social terms, and the repression of this traumatic experience, are the cause of the perturbation that haunts our time. Disorientation pervades philosophy when the entire imaginary to which it had anchored its power to change the world seems to dissolve in the air, when what was silent and distant turns out to be vibrant, more familiar to us than any known proximity. Precisely for this reason, philosophy must rediscover its ability to inhabit times and spaces different from those oriented by the hegemony of capitalist progress, with its correlate of regular catastrophic emergencies and calculated risk. In this essay, I aim to present a perspective in which, instead of coming back straightforwardly ‘down to earth’, philosophy accepts inhabiting the fluctuating disorientation of its own time, itself populated by intermittent and uncertain opportunities of experiencing differently the past and the future—to encounter different relationships with the times that change.

This article approaches the issue of climate change and the response to it in Scotland from the perspective of genres of expectation and normality, focusing in particular on the relationship between genre, the political imagination, and calls for ‘climate realism’. Functioning partly as provocation and partly as a piece of critical theory on the problematic aspects of contemporary genres of expectation in Scotland, it discusses the push for normality as a driving force in the construction of imagined futures in the context of climate change, problematising how this fits with established expectations of the Scottish political imaginary and its futurity. Using the work of the scholar of genre and affect Lauren Berlant and her identification of genre as a means of ‘moving on’, it considers the idea of materially contingent narratives as an exit strategy from the present moment. To illustrate this, it briefly discusses Jenni Fagan’s contemporary climate change novel The Sunlight Pilgrims as an example of ‘irrealist’ confrontation of climate change and how this relates to the concept of the Anthropocene as an everyday experience. Ultimately, it concludes that contemporary attempts at climate realism require engagement with the irreal material circumstances of climate change and the fundamentally ‘super-wicked’ nature of climate processes in order to escape the constraints of progress, restoration, and normalisation as genre structures in discussion of climate futures.

Nowadays it is common to hear the terms climate change, sustainable development and green consumption in the advertisements of different brands or in social networks. In fact, organizations and individuals continuously express a concern for the protection of the planet, so that citizens also demand a commitment to sustainability from companies. Therefore, starting from the dimension of environmental sustainability, this research analyzes the corporate discourse of Spanish traditional energy companies in order to know how they express their environmental sustainability and commitment to climate change mitigation. It also seeks to know the factors that influence customers when contracting their services. To achieve the objectives, a content analysis of the corporate discourse is applied through a review of sustainability reports and websites; as well as an analysis of advertising spots; the selected sample corresponds to 2019. In addition, an online survey was applied in Spain in order to know the vision of users. With these data, the imaginary that exists about environmental sustainability is constructed. The study considered three companies: Iberdrola, Endesa and Naturgy, which are of Spanish origin, are part of the IBEX 35 and, according to the Brand Finance ranking (2020), represent 5% of global investment in the energy sector.

Carbonaceous aerosols emitted from biomass burning influence radiative forcing and climate change. Of particular interest are emissions from high-latitude peat burning because amplified climate change makes the large carbon mass stored in these peatlands more susceptible to wildfires and their emission can affect cryosphere albedo and air quality after undergoing transport. We combusted Siberian peat in a laboratory biomass-burning facility and characterized the optical properties of freshly emitted combustion aerosols and those photochemically aged in an oxidation flow reactor (OFR) with a three-wavelength photoacoustic instrument. Total particle count increased with aging by a factor of 6 to 11 while the total particle volume either changed little (<8%) for 19 and 44 days of equivalent aging and increased by 88% for 61 days of equivalent aging. The aerosol single-scattering albedo (SSA) of both fresh and aged aerosol increased with the increasing wavelength. The largest changes in SSA due to OFR aging were observed at the shortest of the three wavelengths (i.e., at 405 nm) where SSA increased by less than ~2.4% for 19 and 44 days of aging. These changes were due to a decrease in the absorption coefficients by ~45%, with the effect on SSA somewhat reduced by a concurrent decrease in the scattering coefficients by 20 to 25%. For 61 days of aging, we observed very little change in SSA, namely an increase of 0.31% that was caused a ~56% increase in the absorption coefficients that was more than balanced by a somewhat larger (~71%) increase in the scattering coefficients. These large increases in the absorption and scattering coefficients for aging at 7 V are at least qualitatively consistent with the large increase in the particle volume (~88%). Overall, aging shifted the absorption toward longer wavelengths and decreased the absorption Ångström exponents, which ranged from ~5 to 9. Complex refractive index retrieval yielded real and imaginary parts that increased and decreased, respectively, with the increasing wavelength. The 405 nm real parts first increased and then decreased and imaginary parts decreased during aging, with little change at other wavelengths.

Developments within cryobiology have turned the freezing of biological parts into standard clinical procedure. This article turns to the cryopolitics of egg freezing and seed conservation to focus on the cultural imaginaries of (frozen) cells and seeds revealed in the two documentaries: Motherhood on Ice (2014) and Seeds of Time (2014). The cultural imaginaries of frozen cells and seeds reiterate an understanding of reproduction as kinship-through-genes, extending the reproductive temporality of the body and the affective temporalities associated with climate change, turning cells and seeds into desirable insurance objects and objects of human manipulation. The article concludes that while Seeds of Time upholds a masculinist and scientific imaginary of humans as gods over seeds, in Motherhood on Ice, the cultural imaginary cements a gendered and straight temporality in which ice synchronizes straight, white women’s middle-class femininity and reproductive potential with ideals of romantic time.

Indigenous societies provide alternatives to hegemonic social institutions that global capitalism spread around the world, contributing to human caused environmental degradation called the Anthropocene, coterminous with the development of the modern world-system. In this work we describe Indigenous communities using ten social spheres, that balance human needs through ecological mindfulness, including spirituality, and then we model how these social spheres can be adapted to contemporary world-systems using a radical imaginary, building off Indigenous works by Fenelon (2015; 2016), social perspectives of Pellow (2017) and Norgaard (2019), and environmental geospatial sciences (Lui, Springer, and Wagner 2008; Jankowski 2009). We identify four social constructs from Indigenous peoples—(1) decision-making, (2) land tenure and resource management, (3) economic and (4) community—which we model for societies in world-systems through the ten imagined social spheres, to present foundations that empower communities to resist the coming climate change futures of the Anthropocene.

Indigenous African education grew out of the immediate environment, real or imaginary, where people had knowledge of the environment. Indigenous education inculcated a religious attitude that imbued courtesy, generosity, and honesty. At colonization, Africans were thought of as primitive although they had their own systems, contents, and methods of education. Colonialism signified the decline in the importance of indigenous knowledge systems (IKS). By shifting focus in the core curriculum from teaching/learning based on Western science to teaching/learning through IKS as a foundation for all education, it is anticipated that all forms of knowledge, ways of knowing, and world views be acknowledged as equally valid, adaptable, and complementary to one another in equally valuable ways. The uniqueness of indigenous people and their knowledge is inextricably connected to their lands, which are situated primarily at the social-ecological margins of human habitation such as tropical forests and desert margins. It is at these margins that the consequences of climate change manifest themselves in the following sectors: agriculture, pastoralism, fishing, hunting and gathering, and other subsistence activities, including access to water. Government policies in Zimbabwe often limit options and thus undermine indigenous peoples’ efforts to adapt. IKS is very important for community-based adaptation and mitigation actions in the agricultural sector for maintenance of resilience of social-ecological systems at a local level. This article, through interviews, document analysis, and personal observations, proposes that it is best for Zimbabwe to develop her own climate change curricula and modes of delivery that incorporates IKS.

Abstract With technological developments, distant Himalayan ice has largely replaced early scientific accounts that emerged from physical engagement. Ice became an abstraction that in contemporary accounts is commonly enmeshed in a climate change imaginary and aims to contribute to knowledge about something happening at the planetary level. This article proposes a shift in narrative scale, drawing on ethnographic research in the Indian Himalayas. It explores stories of entanglement in icy ecologies, portraying ice not as a mere abstraction but as a vital body. In these accounts, ice is at the centre of mundane and intimate encounters with climate change and its materiality induces a relationship between bodies (humans, non-humans) that transcends their ontological boundaries. Recognizing these experiences is a fundamental element in reimagining Himalayan ice, departing from technological limitations, and underscoring the consequences of ice melting within the context of climate change. Resume Avec les progrès technologiques, la construction à distance de la glace himalayenne en tant que formation épistémique a largement remplacé les premiers récits scientifiques issus d'un engagement physique et sensoriel. La glace est devenue une abstraction qui, dans les récits contemporains, est généralement imbriquée à l'imaginaire du changement climatique et vise à contribuer à la connaissance quant à un phénomène planétaire. Cet article propose un changement d’échelle dans les récits sur la glace himalayenne. S'appuyant sur des recherches ethnographiques menées dans l'Himalaya indien, il explore des récits d'enchevêtrement au sein d’écologies de glace. Dans ces récits, la glace n'est ni une abstraction ni un substrat passif, mais plutôt un corps vital : au centre de rencontres banales et intimes avec le changement climatique, sa matérialité induit une relation entre les corps (humains, non-humains) et transcende leurs frontières ontologiques. Prendre en compte le caractère dispersé de ces expériences offre la possibilité de cultiver un autre type d'imaginaire pour l'Himalaya et ses glaces, un imaginaire qui dépasse les limites imposées par les impératifs technologiques et qui est attentif aux conséquences de la fonte des glaces sous le changement climatique.

This paper examines India's role in perpetuating North-South imaginaries in global climate politics. A Global South perspective on climate politics is premised on the differential contribution of developed and developing countries towards climate change, differential adaptive capacities, and the overriding need of developing countries to focus on poverty alleviation and sustainable development. Meanwhile, the North-South binary has been extensively critiqued in the literature for the heterogeneity of each category, narrowing gaps between North and South, and the state-centrism implicit in such a categorization. Based on the understanding that the reproduction of the North-South frame in climate discourses is inherently political, I examine the politics behind their reproduction, rather than focus on the validity of these categories. Based on fieldwork in Delhi and Copenhagen, my paper provides insight into the spatial politics of climate policy negotiations. The categories North and South, developed and developing, or First World and Third World constitute powerful spatial imaginaries that strongly influence the negotiating positions of Indian officials in global climate politics, even as India's image as a developing country is increasingly questioned in light of its status as an emerging economy and major emitter. The self-identification of Indian officials with the imaginary of the Global South is a crucial feature of global climate politics.

The article examines the peculiarities of implementing international climate policy during the Russian-Ukrainian war. The author identifies the place of our country in it, as well as clarifies the main issues in the field of combating climate change and the prospects for their solution. It is noted that the hostilities only deepen the global climate crisis due to the increase in greenhouse gas emissions from the use of various types of weapons by the Russian invaders. Despite the fact that Ukraine is at war with Russia, the issues of environmental protection and climate change remain relevant. This is confirmed by a number of international events where climate change has become one of the most important topics for discussion, especially in the context of Russia's armed aggression against our country. On the one hand, Russia's full-scale invasion of our country has led to terrible consequences for the environment, which only deepen the climate crisis further, and on the other hand, it has become an impetus for the end of the «fossil fuel era» and the transition to renewable energy sources. Ukraine is an active participant in international climate policy, confidently moving along the European integration path and striving to achieve climate neutrality against all odds. It is noted that Ukraine is the largest country in Europe and climate neutrality for Europe is impossible without climate neutrality for our country. Getting rid of dependence on Russian fossil fuels is the key to ending the war and accelerating the transition of countries to renewable energy sources. Of course, not all states are ready to abandon various types of fossil fuels due to financial and economic interests. Instead, they are looking for new sources of energy. Reaching a consensus on implementing important climate measures in line with the international commitments undertaken by states is becoming increasingly difficult every year. Not all countries are ready to contribute to a good cause and finance large-scale projects to overcome the effects of climate change. Climate justice is an imaginary concept. Despite this, most countries in the world continue to set ambitious climate goals and create the conditions for achieving them. There is every chance to overcome the climate crisis, but only if there is political will and an adequate understanding of the nature of this problem, which affects the present and future of humanity. The adoption of the Climate Solidarity Pact by states can help free countries from coal and gas dependence and facilitate an effective transition to renewable energy sources. Our state occupies a prominent position in international climate policy. Despite all the consequences of Russia's full-scale invasion, it is only moving forward and is not going to retreat from its plans, especially in the area of climate change. Ukraine continues to follow the European Green Deal, gradually integrating the environmental and climate component into all sectors of the economy, and to work with international partners on a plan for the post-war restoration of our state on the basis of energy independence, climate security and sustainable development, and to bring Russia to international responsibility for the crime of ecocide. Keywords: greenhouse gas emissions, fossil fuels, «green» transformation, climate change, European Green Deal, climate crisis, Paris Agreement.

Combining real-life story and dystopian tropical imaginary, the author takes us to the Straits of Malacca off the coast of Peninsular Malaysia, to futures of submerged cities in 2050, and on a final journey into the South China Sea off the coast of Sarawak on the island of Borneo. This is a story of climate change and rising seas entwining vignettes of pandemic lockdown, of a father’s dying, and the author’s future life submerged. It questions human survival in a world of demise, shaped by pandemic and surrounded by waters slowly but inexorably rising.

Abstract In a widely shared video, the government of the island state of Tuvalu posed an imaginary of Tuvalu as a digital nation in a situation of unabated climate change. In this article, we take the example of Digital Tuvalu as a paradigmatic case to advance the debates on international relations in the Anthropocene, demonstrating how the processes of climate catastrophe and digital state formation juxtapose. In linking climate loss and state extinction to notions of virtual sovereignty and cyber statehood, we are attentive to the infrastructural power of large information and communications technology companies, while at the same time acknowledging the agency of the Tuvaluan state in navigating the challenges of the Anthropocene. We discuss how a virtual deterritorial state mobilizes the Tuvaluan indigenous philosophy of fenua, to link land, sea, people and culture in a relational understanding of territory and sovereignty. Digital Tuvalu in this way envisions emerging digital technologies to rebuild Tuvaluan fenua in virtual space, thereby regaining agency in the face of existential climate threats. This, we argue, signals a new and highly relational model of digital state preservation, having profound implications for international relations in the Anthropocene.

Abstract. Climate change assessment, especially model evaluation, requires a better understanding of complex refractive indices (CRIs) of atmospheric aerosols – separately for both fine and coarse modes. However, the widely used aerosol CRI obtained by the global Aerosol Robotic Network (AERONET) corresponds to total-column aerosol particles without separation for fine and coarse modes. This paper establishes a method to separate CRIs of fine and coarse particles based on AERONET volume particle size distribution (VPSD), aerosol optical depth (AOD) and absorbing AOD (AAOD). The method consists of two steps. First a multimodal log-normal distribution that best approximates the AERONET VPSD is found. Then the fine and coarse mode CRIs are found by iterative fitting of AERONET AODs to Mie calculations. The numerical experiment shows good performance for typical water-soluble, biomass burning and dust aerosol types, and the estimated uncertainties on the retrieved sub-mode CRIs are about 0.11 (real part) and 78 % (imaginary part). The 1-year measurements at the AERONET Beijing site are processed, and we obtain CRIs of 1.48–0.010i (imaginary part at 440 nm is 0.012) for fine mode particles and 1.49–0.004i (imaginary part at 440 nm is 0.007) for coarse mode particles, for the period of 2014–2015. Our results also suggest that both fine and coarse aerosol mode CRIs have distinct seasonal characteristics; in particular, CRIs of fine particles in winter season are significantly higher than summer due to possible anthropogenic influences.

In this article, the author argues that anti-colonial Marxism has been obscured and distorted by the contemporary post-Cold War imaginary. The author analyzes the historical-political context in which the narrative of Marxism and decolonization develop during and after the Cold War. Focusing on the writings of Frantz Fanon, Amílcar Cabral, Thomas Sankara, and Ernesto “Che” Guevara, the author reconstructs the “principles” of anti-colonial Marxism, attempting to ameliorate the scholarly deficit of theoretical literature on the anti-colonial Marxist tradition. In conclusion, the author argues that the “revolutionary theory” of these thinkers remains relevant to persistent, present-day conditions of neocolonialism and capitalist imperialism, becoming increasingly relevant with the progression of catastrophic climate change.

Abstract Reimagining human-nature relationships in the climate change era conjures mutants, creatures from the deep that help surface modes of becoming for a drenched world of rising tides, plastic oceans, and soaked cities. Re-imaging deep, embodied relations with watery ecologies, then, also involves attention to speculative climate fictions (cli-fi) and the potential worlds they help fathom. Cli-fi renderings of climate disaster provide critical insight into possible alternative arrangements of power, meaning, and ontological status. As such, this article explores the depths of the 1995 cli-fi film Waterworld, offering an ecocritical analysis of how the film’s mutant imaginary might help us fathom how to flourish amid floods and contest the very human forces/forms that shape them. In Waterworld, the authors find queer elemental bodies collaborating with ecology and embracing their inherent impurities. This classic cli-fi film provides an important touchstone for a future in which dominant petro-masculine approaches to pelagic place are found to be drowned, dead ends. This article amplifies how mutant corporeal formations and elemental agencies in Waterworld swirl together to submerge systems of power and privilege and drench binaries. Ultimately, Waterworld’s queer ecology helps morph what and how it means to live in a flooded future as speculative seascapes seep into everyday contemporary climate life.

Abstract. A central diagnosis driving research around social relations of nature is the thesis of the “end of nature”. In an era marked by climate change and global warming, the image of nature as a pristine and stable foundation of human existence seems outdated. In light of this, recent scholarship demonstrates how environmental changes and conflicts increasingly affect people's daily lives and present significant threats to psychic well-being. In contrast, in this paper we investigate the conditions under which nature continues to function as an effective source of `ontological security'. As part of an international comparative research project that engages geographical imaginaries of security and insecurity in Berlin, Vancouver, and Singapore, we analyze how nature is imagined by city dwellers as an object of desire that offers a place of refuge to escape the burdens from urban everyday life. Against this background, we emphasize imaginary nature as a powerful everyday source for the ontological security of subjects even under today's postnatural conditions.

Tourism started slowly in Ilulissat (Greenland) in the 1980s-1990s, before expanding further in the 21st century since the UNESCO classification of the Sermeq Kujalleq Glacier Fjord and the fact that the Arctic has become a symbol of climate change. These journeys are both imaginary, described as «cryotropism», «borealism» or «nordicity», and very real: the impact of tourism is visible in the environment. A new international airport is planned for 2023. What type of tourist and there‑ fore travel will this attract? We asked ourselves to what extent the Ilulissat natural site could be managed in a sustainable way. In order to answer this question, we adopted the participant obser‑ vation from an immersion in the Ilulissat Fjord Office and conducted about twenty semistructured interviews.

In his 2019 book The Unconstructable Earth: An Ecology of Separation, Frédéric Neyrat opposes the idea that, having come very close to destroying the Earth in the Anthropocene, man can now use geoengineering to reconstruct it. Instead, Neyrat proposes an “ecology of separation” which recognizes the Earth’s self-regenerating capacity as essentially separate from man’s intrusion, thus suggesting that the condition for the world to survive in an age of increasing apocalyptic dangers is an acceptance of the limitations of human agency. This article will argue that Amitav Ghosh’s own ecological project, developed in his 2016 essaybook The Great Derangement: Climate Change and the Unthinkable, which started as early as his historical opium war novel Sea of Poppies (2008), narrates an ecology of separation similar to Neyrat’s, a version of Graham Huggan and Helen Tiffin’s “green postcolonialism” that confronts Eurocentric aggression against non-European civilizations and against nature

This article reviews how global hydropower assemblages catalyze socioecological change in the world’s rivers. As a quintessential megaproject, massive dams and the hydropower they generate have long captivated the modernist development imaginary. Yet, despite growing recognition of the socio-ecological consequences of hydropower, it has recently assumed a central role in supporting renewable energy transitions. We highlight three trends in hydropower politics that characterize global hydropower assemblages: mega-dams as markers of nation-state development; river protection by territorial alliances and social movements opposed to hydropower; and transitions from spectacular, centralized hydropower installations to the propagation of small and large hydropower within climate mitigation schemes. We offer insights on how global hydropower assemblages force examination beyond traditional categories of “mega” through more holistic and grounded analyses of significance.

AbstractThe Antarctic Treaty of 1959, which dedicates the continent to peace and international scientific cooperation in the face of rising east–west tensions, is informed in part by a shared scientific imaginary created by the UK and other nations which maintained scientific bases in Antarctica at the time. In this article, the poet offers works extracted from her longer sequence “Met Obs,” based on meteorological reports and journals from the UK station at Port Lockroy written in advance of the 1957–1958 International Geophysical Year (IGY). The poems engage with the work and circumstances which helped foster such an imaginary, as well as with the nexus of Antarctic “values” endorsed by the Treaty, and the later Madrid Protocol. The commentary further contextualises these literary responses in terms of the attitudes of the men working there as well as the “wilderness and aesthetic values” recognised by the later Protocol on Environmental Protection. The world of the poems may belong to 1950s Antarctica, but their observations reach beyond that experience, making a case for the continued relevance of Treaty values, and for the importance of artistic, as well as scientific, responses to the environment in a world under threat from accelerating climate change and competition for resources.

Abstract. Better characterization of the optical properties of aerosol particles are an essential step to improve atmospheric models and satellite remote sensing, reduce uncertainties in predicting particulate transport, and estimate aerosol forcing and climate change. Even natural aerosols such as mineral dust or particles from volcanic eruptions require better characterization in order to define the background conditions from which anthropogenic perturbations emerge. We present a detailed laboratorial study where the spectral optical properties of the ash from the April–May (2010) Eyjafjallajökull volcanic eruption were derived over a broad spectral range, from ultra-violet (UV) to near-infrared (NIR) wavelengths. Samples of the volcanic ash taken on the ground in the vicinity of the volcano were sieved, re-suspended, and collected on filters to separate particle sizes into fine and mixed (coarse and fine) modes. We derived the spectral mass absorption efficiency αabs [m2g−1] for fine and mixed modes particles in the wavelength range from 300 to 2500 nm from measurements of optical reflectance. We retrieved the imaginary part of the complex refractive index Im(m) from αabs, using Mie–Lorenz and T-matrix theories and considering the size distribution of particles obtained by scanning electron microscopy (SEM), and the grain density of the volcanic ash measured as ρ = 2.16 ± 0.13 g cm−3. Im(m) was found to vary from 0.001 to 0.005 in the measured wavelength range. The dependence of the retrieval on the shape considered for the particles were found to be small and within the uncertainties estimated in our calculation. Fine and mixed modes were also analyzed by X-ray fluorescence, exhibiting distinct elemental composition supporting the optical differences we found between the modes. This is a comprehensive and consistent characterization of spectral absorption and imaginary refractive index, density, size, shape and elemental composition of volcanic ash, which will help constrain assumptions of ash particles in models and remote sensing, thereby narrowing uncertainties in representing these particles both for short-term regional forecasts and long-term climate change.

Carbon emission has been considerably higher in India in the last few decades. The greenhouse gases increased to an imaginary volume, a major contributor to global warming. Chennai is one of India’s large cosmopolitan cities, contributing more Gross Domestic Product (G.D.P.) and carbon to the atmosphere. The infrastructure sector is always a booming sector in and around Chennai, which requires more construction materials. In turn, the construction of new buildings expands the city with a large area of urban and suburban Chennai, where I.T. division, automobile division, and industrial estates are available. Hence, this study deals with the carbon emission of a residential building constructed with conventional materials in and around Chennai. So, one can estimate the emission of carbon by the conventional building, which leads to global warming and climate change.

Humanity’s self-ordained mandate to subdue and dominate nature is part of the cognitive foundation of the modern world—a perspective that remains deeply ingrained in science and technology. Marine biology has not been immune to this anthropocentric bias. But this needs to change, and the gaps between basic scientific disciplines and the global conservation imperatives of our time need to be bridged. In the face of a looming ecological and climate crisis, marine biologists must upgrade their values and professional standards and help foster the radical transformation needed to avert a climate and ecological breakdown. To prevent some of the damage, they must cross the imaginary line that separates science from science-based activism and consciously pursue the health and durability of human and natural communities. To this end, they can (1) develop compelling narratives that engage human society, with emphasis on care for the wild living world; (2) move beyond marine conservation on paper and avoid self-serving complaisance; (3) advocate constructive changes in market and human behaviour, not only by documenting damage but also by clarifying how the extraction, production and consumption system can be steered away from practices that harm nature; (4) push for systemic change in politics through individual and collective efforts, supporting environmental activism and those who demand biosphere-saving policies; and (5) endorse a more ecocentric and holistic world vision, relinquishing contempt for spiritual wisdom and liaising with (or at least not dismissing) spiritual traditions that encourage equality, self-restraint and environmental sustainability.

Abstract Craft artists can be simultaneously mythical poets and SciFy specialists, whose craft skills from the past act as a tool-kit to overcome the borders between past and future, to predict and create imaginary new worlds and to point towards solutions for the future. The Nordic culture and its craft tradition is a wise model for future generations in tackling climate change, social problems and waste. While current design students are outstandingly talented and skilful users of digital tools of virtual reality, problems arise when perfect virtual images have to be transformed into real 3D models, prototypes and products. Designers who are trained to combine craft skills and experiential knowledge with digital reality and computer-assisted tools appear to have an advantage in innovation because they can predict and overcome the flaws that digital reality overlooks.

A PhD student shares part of her arts-based praxis process of developing a relational model of curriculum oriented towards reconciliation in Canada and South Africa by reflecting on a pilot course she offered at a university in Canada in 2018. This site-specific, media arts-based environmental education is intended for universities committed to walking the talk of decolonising education. Centered around water as a mirror of the state of our social relations and democracy, which it seeks to transform, the curriculum also facilitates public education and dialogue around the importance of healthy waterways amidst the pressures of climate change. Using a set of questions as a data analysis tool combined with narrative analysis of students’ videos, the researcher outlines the three most prominent relational sensibilities and abilities towards reconciliation cultivated by students through the program: (1) Knowledge Ecologies; (2) A Hopeful Social Imaginary; and (3) Embodied Ways of Knowing.

Sea level rise due to climate change is predicted to be higher in the Tropics. As a low-lying, highly urbanised island near the equator, Singapore is taking an active response to this problem, including through large land reclamation projects. Incorporating both environmental and aesthetic elements, these projects also serve to bolster Singapore’s reputation as a shining example of a global city, a leading arts centre in Southeast Asia, and an economic hub to the world. This paper draws attention to urban development through an ethnographic reading of Yeo Siew Hua’s film A Land Imagined. A Singaporean tropical-noir mystery thriller, the film follows the rhizomatic path of a police investigator and his partner as they attempt to solve the disappearance of two foreign labourers. Interwoven within the film is a critique of Singapore’s treatment of migrant workers as it constructs the imaginary of the ‘Singapore Dream’.

Abstract. One of the major uncertainties in the understanding of Earth's climate system is the interaction between solar radiation and aerosols in the atmosphere. Aerosols exposed to high humidity will change their chemical, physical, and optical properties due to their increased water content. To model hydrated aerosols, atmospheric chemistry and climate models often use the volume weighted mixing rule to predict the complex refractive index (RI) of aerosols when they interact with high relative humidity, and, in general, assume homogeneous mixing. This study explores the validity of these assumptions. A humidified cavity ring down aerosol spectrometer (CRD-AS) and a tandem hygroscopic DMA (differential mobility analyzer) are used to measure the extinction coefficient and hygroscopic growth factors of humidified aerosols, respectively. The measurements are performed at 80% and 90%RH at wavelengths of 532 nm and 355 nm using size-selected aerosols with different degrees of absorption; from purely scattering to highly absorbing particles. The ratio of the humidified to the dry extinction coefficients (fRHext(%RH, Dry)) is measured and compared to theoretical calculations based on Mie theory. Using the measured hygroscopic growth factors and assuming homogeneous mixing, the expected RIs using the volume weighted mixing rule are compared to the RIs derived from the extinction measurements. We found a weak linear dependence or no dependence of fRH(%RH, Dry) with size for hydrated absorbing aerosols in contrast to the non-monotonically decreasing behavior with size for purely scattering aerosols. No discernible difference could be made between the two wavelengths used. Less than 7% differences were found between the real parts of the complex refractive indices derived and those calculated using the volume weighted mixing rule, and the imaginary parts had up to a 20% difference. However, for substances with growth factor less than 1.15 the volume weighted mixing rule assumption needs to be taken with caution as the imaginary part of the complex RI can be underestimated.

The crafts sector, traditionally characterized by its adherence to heritage and small-scale familial enterprises, confronts an array of unprecedented challenges stemming from rapid technological advancement, globalization, climate change, and shifting demographics. This article presents a pioneering investigation into the profound and transformative effects of digitalization on the crafts sector, offering novel insights into the future trajectory of this industry. Through an explorative approach, we critically examine and interrogate the social imaginary underpinning the crafts sector, shedding light on the intricate interplay between tradition and innovation. Leveraging an inter- and transdisciplinary framework, our research brings together academics, experts, and practitioners from diverse regions in Italy and Austria to explore the nexus of digitalization and craft futures. We introduce three future scenarios for the crafts sector, each delineating varying degrees of digitalization and their potential implications. Employing a mixed-method approach encompassing expert interviews, a Delphi survey, focus groups, and scenario development, our study offers a comprehensive exploration of the multifaceted landscape of craft futures. Furthermore, through the visualization of these scenarios, we provide a tangible platform for envisioning and engaging with the myriad possibilities that lie ahead. By synthesizing innovative methodologies from future studies and social imaginaries with a specific focus on the crafts sector, our research offers a robust analytical framework for navigating the complex dynamics of digitalization and envisioning transformative futures. This paper not only illuminates the disruptive forces unleashed by digitalization but also provides strategic insights to inform future decision-making processes within the crafts sector and beyond.

Abstract. Secondary organic aerosol (SOA) has great impacts on air quality, climate change and human health. The composition and physicochemical properties of SOA differ greatly because they form under different atmospheric conditions and from various precursors as well as differing oxidation. In this work, photooxidation experiments of toluene were performed under four conditions (dry, dry with SO2, wet and wet with SO2) to investigate the effect of SO2 under different relative humidities on the composition and optical properties of SOA at wavelengths of 375 and 532 nm. According to our results, the increase in humidity enhances not only light absorption but also the scattering property of the SOA. Oligomers formed through multiphase reactions might be the reason for this phenomenon. Adding SO2 slightly lowers the real part of the complex refractive index, RI(n), of toluene-derived SOA (RI(n)dry,SO2<RI(n)dry, RI(n)wet,SO2<RI(n)wet), which might be a result of the partitioning of low-oxidation-state products. The imaginary part of the complex refractive index, RI(k), is enhanced under dry conditions with SO2 compared to that of only dry conditions, which might be due to acid-catalyzed aldol condensation reactions. Wet conditions with SO2 shows the combined effect of SO2 and humidity. The extinction properties of toluene-derived SOA under wet conditions with SO2 increased by approximately 30 % compared to that of toluene-derived SOA formed under dry conditions. Our results suggest that various atmospheric conditions will affect the composition and optical proprieties of SOA, which has significant implications for evaluating the impacts of SOA on the rapid formation of regional haze, global radiative balance and climate change.

Aim: To examine innovative geotechnical solutions for sustainable infrastructure development. Problem Statement: The advancement in the world urbanization together with high rise in global population has alarmed the need for new infrastructures with additional innovative research to be conducted with already existing assets. Thus, It is important that geotechnical engineering should include basic practices targeting resource-efficient and environment-friendly techniques in order to add to sustainable development. Significance of Study: This technical review critically examines the innovative geotechnical solutions for sustainable infrastructure development. The content presented in this manuscript will be beneficial to professionals in the area of geotechnical engineering. Methodology: Recent relevant published articles in the area of innovative geotechnical solutions for sustainable infrastructure development were consulted. These include journal articles, conference papers, Asian Development Bank articles and unpublished doctoral documents. Discussion: The six main environmental objectives of the Taxonomy Regulation to ensure the contours of an environmentally sustainable infrastructure were stated to include: (1) sustainable protection and use of marine and water resources (2) pollution control and prevention (3) switch to a circular economy (4) mitigation of climate change (5) restoration and protection of ecosystems and biodiversity and (6) adaptation of climate change. The three phase methods for sustainability infrastructure development in geotechnics were critically discussed. An imaginary excavation site in the municipality of Rozzano was referenced as a case study to reveal the application of the proposed methodology to the soil treatment systems. It was noticed that the adoption of an LCA introduces additional deep knowledge and the required quantitative analysis for sizing the assessment. Conclusion: The examined innovative geotechnical solutions were contributory to sustainable infrastructure development.

AbstractVance and Nettie Palmer were among Australia's most important literary partnerships. Previous accounts of their life and work underplay their commitment to the creation of an environmental imagination. After the trauma and disillusion of the Great War, they lived in Caloundra from 1925 to 1929 (and from then had an ongoing connection). While it is generally acknowledged how important their time there was in terms of Vance's emerging work in literary fiction, and through Nettie's work as a freelance journalist, what has not been addressed is their extraordinary environmental writings about the region. Regional writings were largely dismissed in the 1990s as of comparative insignificance to national narratives — just as today the reputation of the inter-war writers, those associated with the Palmers, is at a low ebb. During the 1920s, Nettie developed critical categories to accommodate a double standard in Australian writing: regional and universal literature. She went on to argue for the support of writing in Australia at the regional level. Vance reflected on his explorations of place directly in a series of articles. This paper reframes the Palmers’ Caloundra work in the ‘bio-regional’ terms of climate change and the historical cultural imaginary.

Authors' note: Science fiction writers construct an imaginary future; historians attempt to reconstruct the past. Ultimately, both are seeking to understand the present. In this essay, we blend the two genres to imagine a future historian looking back on a past that is our present and (possible) future. The occasion is the tercentenary of the end of Western culture (1540 – 2073); the dilemma being addressed is how we – the children of the Enlightenment – failed to act on robust information about climate change and knowledge of the damaging events that were about to unfold. Our historian concludes that a second Dark Age had fallen on Western civilization, in which denial and self-deception, rooted in an ideological fixation on “free” markets, disabled the world's powerful nations in the face of tragedy. Moreover, the scientists who best understood the problem were hamstrung by their own cultural practices, which demanded an excessively stringent standard for accepting claims of any kind – even those involving imminent threats. Here, our future historian, living in the Second People's Republic of China, recounts the events of the Period of the Penumbra (1988 – 2073) that led to the Great Collapse and Mass Migration (2074).

Taking the new materialist and climate change themes of Ashley Fure’s The Force of Things: an Opera for Objects as a departure point, this article examines sound studies’ recent invocations of new materialist philosophy alongside this philosophy's foundational concern toward the Anthropocene ecological crisis. I argue that new materialist sonic thought retraces new materialism’s dubious ethical program by deriving equivalencies of moral standing from logically prior ontological equivalencies of material entities and social actors rooted in their shared capacities to vibrate. Some sonic thought thus amplifies what scholars in Black and Indigenous decolonial critique have exposed as the homogenizing, assimilative character of new materialism’s superficially inclusional and optimistic ontological imaginary, which includes tendencies to obscure the ongoingness of racial inequality and settler-colonial exploitation in favor of theorizing difference as a superfice or illusion. As I argue in a sonic reading of Frantz Fanon’s Black Skin, White Masks, some of new materialism’s favored analytical and ecological terms such as objecthood, vibrationality, and connection to the Earth are also terms through which anti-Blackness, colonial desire, and the universalization of Whiteness have historically been routed. This historical amnesia in new materialism enables its powerfully obfuscating premises. As a result, I argue that new materialist sound studies and philosophy risk amplifying the Anthropocene’s similarly homogenizing rhetorics, which often propound a mythic planetary oneness while concealing racial and colonial climate inequities. If sound studies and the sonic arts are to have illuminating perspectives on the Anthropocene, they must oppose rather than affirm its homogenizing logics.

En este artículo analizamos la emergencia de imaginarios ante la crisis climática a partir de una investigación etnográfica y de un análisis visual narrativo de 231 imágenes vinculadas a cuentas de Instagram dedicadas a la divulgación de contenidos medioambientales. Proponemos que estos activistas (que denominamos eco-influencers) están creando narrativas que dialogan con el imaginario social vinculado con la modernidad, cuestionando la separación entre naturaleza y cultura (propia de dicho imaginario) y proponiendo una reconexión con la naturaleza.

The article develops a geopoetic approach to Russian Arctic politics. It rests on the empirical observation that due to climate change, the Arctic landscape is undergoing profound transformations, which has led to multilateral governance efforts but also unilateral pursuits. In this general heterogeneity, Russia’s policies have raised the most pressing questions regarding the country’s motivations to engage in the region. Cultural approaches to global politics are most suitable to create holistic understandings and explanations in this regard, but they lack discussing a spatial dimension of Russian identity. By developing a geopoetic account, the article complements this research through methodological insights from critical geography. Geopoetics focuses on the cultural roots and their cognitive-emotional dimension, on the basis of which claims to the Arctic and related policies resonate with a broader audience. The article argues that Russian policies have their foundation in a utopian ideal of Soviet socialist realism that was widely popularised in the 1920s and later decades. Applying the hermeneutic tool of topos, the article highlights that three features stand out that interweave into a coherent imaginary of the Arctic: first, the heroic explorer; second, the conquest of nature; and third, the role of science and technology. Analysts would do well to bear in mind how the Arctic becomes intelligible when commenting on policies.

Abstract. Modeling the interaction of dust with long-wave (LW) radiation is still a challenge because of the scarcity of information on the complex refractive index of dust from different source regions. In particular, little is known about the variability of the refractive index as a function of the dust mineralogical composition, which depends on the specific emission source, and its size distribution, which is modified during transport. As a consequence, to date, climate models and remote sensing retrievals generally use a spatially invariant and time-constant value for the dust LW refractive index. In this paper, the variability of the mineral dust LW refractive index as a function of its mineralogical composition and size distribution is explored by in situ measurements in a large smog chamber. Mineral dust aerosols were generated from 19 natural soils from 8 regions: northern Africa, the Sahel, eastern Africa and the Middle East, eastern Asia, North and South America, southern Africa, and Australia. Soil samples were selected from a total of 137 available samples in order to represent the diversity of sources from arid and semi-arid areas worldwide and to account for the heterogeneity of the soil composition at the global scale. Aerosol samples generated from soils were re-suspended in the chamber, where their LW extinction spectra (3–15 µm), size distribution, and mineralogical composition were measured. The generated aerosol exhibits a realistic size distribution and mineralogy, including both the sub- and super-micron fractions, and represents in typical atmospheric proportions the main LW-active minerals, such as clays, quartz, and calcite. The complex refractive index of the aerosol is obtained by an optical inversion based upon the measured extinction spectrum and size distribution. Results from the present study show that the imaginary LW refractive index (k) of dust varies greatly both in magnitude and spectral shape from sample to sample, reflecting the differences in particle composition. In the 3–15 µm spectral range, k is between ∼ 0.001 and 0.92. The strength of the dust absorption at ∼ 7 and 11.4 µm depends on the amount of calcite within the samples, while the absorption between 8 and 14 µm is determined by the relative abundance of quartz and clays. The imaginary part (k) is observed to vary both from region to region and for varying sources within the same region. Conversely, for the real part (n), which is in the range 0.84–1.94, values are observed to agree for all dust samples across most of the spectrum within the error bars. This implies that while a constant n can be probably assumed for dust from different sources, a varying k should be used both at the global and the regional scale. A linear relationship between the magnitude of the imaginary refractive index at 7.0, 9.2, and 11.4 µm and the mass concentration of calcite and quartz absorbing at these wavelengths was found. We suggest that this may lead to predictive rules to estimate the LW refractive index of dust in specific bands based on an assumed or predicted mineralogical composition, or conversely, to estimate the dust composition from measurements of the LW extinction at specific wavebands. Based on the results of the present study, we recommend that climate models and remote sensing instruments operating at infrared wavelengths, such as IASI (infrared atmospheric sounder interferometer), use regionally dependent refractive indices rather than generic values. Our observations also suggest that the refractive index of dust in the LW does not change as a result of the loss of coarse particles by gravitational settling, so that constant values of n and k could be assumed close to sources and following transport. The whole dataset of the dust complex refractive indices presented in this paper is made available to the scientific community in the Supplement.

The story of AVATAR happened in an imaginary planet Pandora. It is in the nearest stellar system from us, which is a triple star system located in the constellation Centauri. Currently, only one Earth-size planet has been detected around Proxima Centauri in 2016 by radial velocity technique, and any Jupiter-size planet has been ruled out around all the three stars. The result is in conflict with the scenario in AVATAR film, where Pandora is an Earth-size moon of Polyphemus, a Jupiter-size planet around Centauri B. Earth-size planets in habitable zones around Centauri A and Centauri B are still possible but have not been detected in the precision of current observations. Considering the dynamical complexity of planets in triple star system, which may induce extreme climate change in the possible habitable planets to prohibit development of civilization, we take long-term orbital revolution simulation to explore the stability of Earth-size planet in habitable zones around stars. We focus on habitable planets around Centauri A and Centauri B, as they are close, the average distance between them is small than the size of Solar system. We found that habitable planets with orbits aligned with the binary orbit are long-term stable. However, the orbital eccentricity and inclination changes a lot, if the planetary orbits significantly are tilted with the binary orbit. In comparison with the Milankovitch cycles observed in paleoclimate, we conclude that the titled planets in habitable zone around Centauri A and Centauri B cannot support development of intelligent life.
