Description: What role do socio-demographic and local environmental factors play in the perception of climate change? The article of Landwehr et al. to be discussed here presents interdisciplinary findings on this question, which are particularly interesting regarding the group of farmers. However, the findings also raise questions about the degree of abstraction of climate perception, the rigidity of social identity, the role of the media and the strategy of targeting. In the context of recent “farmer protests” and populist narratives, the author of this response concludes that future interdisciplinary research projects on climate perceptions should also analyse political variables and the relevance of populist discourses.

Description: Welche Rolle spielen sozio-demografische und lokale Umweltfaktoren für die Klimawandelwahrnehmung? Der hier besprochene Artikel von Landwehr et al. stellt interdisziplinäre Befunde zu dieser Frage vor, die besonders mit Blick auf die Gruppe der Landwirt(inn)e(n) interessant sind. Die Befunde werfen aber auch Fragen zum Abstraktionsgrad der Klimawahrnehmung, der Rigidität sozialer Identität, der Rolle der Medien und der Zielgruppenstrategie auf. Im Kontext der jüngsten ,,Bauernproteste“ und populistischer Narrative folgert der Autor dieser Reaktion, dass in künftigen interdisziplinären Forschungsprojekten zur Klimawahrnehmung auch politische Variablen und die Relevanz populistischer Diskurse untersucht werden sollten.

Description: Climate change poses a threat to the agricultural sector, increasing the risk of crop failures, food insecurity and poverty. Given the need for an efficient allocation of scarce adaptation finance, scientific evidence can help to guide the prioritization of adaptation options. This article offers reflections on lessons learned from the AGRICA project, a collaboration between the Potsdam Institute for Climate Impact Research (PIK) and Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ). Running from 2018 to 2024, AGRICA aimed to provide scientific evidence on climate risks, related impacts and suitable adaptation strategies for the agricultural sector in sub-Saharan Africa. Bringing together insights from science, development cooperation and policy, we argue for the need to produce and use rigorous scientific evidence for adaptation policy and planning, including for the formulation and implementation of ambitious National Adaptation Plans (NAPs) and Nationally Determined Contributions (NDCs). This is motivated by assessments such as from the IPCC (2022), which deems current NDC efforts in the agricultural sector insufficient for achieving the Paris Agreement. We discuss lessons learned with a focus on trade-offs between in-depth and standardized assessments, data availability and spatial resolution, modelling uncertainty and methodological pluralism to bridge the science-policy gap.

Description: This chapter provides an overview of the transhumanist movement, its origins, its main figures and its main positions. It then highlights the fact that transhumanism shows little concern for environmental issues, as it is mostly focused on individual bodies, health and longevity. Finally, this chapter examines how transhumanists activists or related academics address contemporary ecological disasters, focusing on the human engineering hypothesis first, and then the “good Anthropocene” and its connections with some aspects of the debate on solar geoengineering.

Description: Today, populism is widely understood to entail an exclusionary conception of “the people” that threatens climate change action. While this threat is real, I argue that populism itself can be understood as a response to perceived exclusion and marginalization, making it possible to conceptualize a more heterogeneous conception of populism’s “people.” Examining two approaches to climate change action rooted in contrasting conceptions of the people and the elite, I argue that climate justice organizing offers a promising effort to construct a heterogeneous people and offers a powerful critique of the elite representation of climate change action in which “we are all in this together.” Yet along with this promise, climate justice organizing must navigate tensions that are inescapable within any populist formation. One neglected thread of populist history and theory offers resources for doing so; in the final section of this paper, I explore its relevance to climate justice today.

Description: The debate on how to evaluate and manage risks focuses on three major strategies: (Renn O. EMBO Rep 8:303–305, 2007, Renn O. Risk governance. Coping with uncertainty in a complex world. Earthscan, London, 2008a; Stirling A. On ‘Science’ and ‘Precaution’ in the management of technological risk. Volume I: synthesis study, report to the eu forward studies unit by European Science and Technology Observatory (ESTO), EUR19056EN. IPTS, Sevilla. Available at: ftp://ftp.jrc.es/pub/EURdoc/eur19056IIen.pdf, 1999): (1) risk-based approaches, including, numerical thresholds (NOEL standards, performance standards, etc.); (2) reduction activities derived from the application of the precautionary principle (examples are ALARA, i.e., as low as reasonably achievable, BACT, i.e., best available control technology, containment in time and space, or constant monitoring of potential side-effects); and (3) standards derived from discursive processes such as roundtables, deliberative rulemaking, mediation or citizen panels. Experience demonstrates that there is no simple recipe for assessing, evaluating and managing risks. In view of complex cause-effect relationships, diverse attitudes and preferences as well as variations in interests and values, risks must be considered as physically as well as socially heterogeneous phenomena that preclude standardized evaluation and handling. Therefore, a coherent concept for evaluation and management is needed that ensures the integration of social diversity and multidisciplinary approaches into institutional routines and standardized practices. The main objective of this paper is to explore the potentials and the limitations of an approach to risk assessment and management that has been labelled the “precautionary principle”. In its most simple version, precaution requires risk managers to err on the safe side. This includes rather accepting false negative (that risks are less severe than assumed) than false positive assessments (that risk are more severe than assumed). However, such a simple definition does not specify to what degree false negatives are socially tolerable, nor does it allow a discussion about future benefits that could potentially compensate for uncertain risks. The following sections will review main positions on precaution and point out the present practice in the European Union, which has adopted the precautionary principle as a major legal guideline for its risk management practice. The paper concludes with suggestions for aligning the precautionary principle and the concept of responsible innovation.

Description: Policy advice for dealing with major crises has focussed on two concepts: resilience and sustainability. The article introduces the term resilience and explains its application in different disciplines. Furthermore, it explores the relationship between resilience and sustainability, illustrates the various concepts that are associated with each term and suggests an integrative approach that is based on the ideal of maintaining critical services for reaching humane living conditions for present and future generations based on fair distribution rules and inclusive governance processes.

Description: Carbon prices in the EU emissions trading system are a key instrument driving Europe’s decarbonization. Between 2017 and 2021, they surged tenfold, exceeding €80 tCO2−1 and reshaping investment decisions across the electricity and industry sectors. What has driven this increase is an open question. While it coincided with two significant reforms tightening the cap (‘MSR reform’ and ‘Fit for 55’), we argue that a reduced supply of allowances alone cannot fully explain the price rise. A further crucial aspect is that actors must have become more farsighted as the reform signalled policymakers’ credible long-term commitment to climate targets. This is consistent with model results that show historic prices can be better explained with myopic actors, whereas explaining prices after the reforms requires actors to be farsighted. To underline the role of credibility, we test what would happen if a crisis undermines policy credibility such that actors become myopic again, demonstrating that carbon prices could plummet and endanger the energy transition.

Description: Emission inventories are a critical basis for air quality and climate modeling, as well as policy decisions. Non-methane volatile organic compounds (NMVOCs) are key precursor compounds in ozone and secondary organic aerosol formation. Accurately representing NMVOCs in emission inventories is crucial for understanding atmospheric chemistry, the impact of policy measures, and climate projections. Improving NMVOC representation in emission inventories is fraught with challenges, ranging from the lack of (long-term) NMVOC measurements, limited efforts in updating emission factors, to the diversity of NMVOC species reactivity. Here we take an initial step to evaluate the representation of urban NMVOC speciation in an emission inventory (EDGARv4.3.2 and EDGARv6.1) at the global level. To compare the urban measurements of NMVOCs to the emission inventory estimates, ratios of individual NMVOCs to acetylene are used. Owing to limitations in measurement data and grouping of NMVOCs in emission inventories, the comparison includes only a limited number of alkanes, alkenes, and aromatics. Results show little to no agreement between the ratios in the observations and those in the global emission inventory for the species compared (r2 0.01–0.20). This could be related to incorrect speciation profiles and/or spatial allocation of NMVOCs to urban areas. Regional emission inventories show better agreement among the ratios (r2 0.43–0.70). The inclusion of oxygenated species in NMVOC measurements, as well as greater global coverage of measurements could improve representation of NMVOC species in emission inventories, and a mosaic of regional inventories may be a better approach.

Description: The international UN Climate Change conferences known as “Conferences of the Parties (COPs)” have an enormous convening power and are attended annually by tens of thousands of actors working on climate change topics from a wide range of perspectives. In the COP spaces outside of the formal negotiations, the communication culture is dominated by “side events,” a format that relies heavily on conventional presentations and panels that can be informative, but is generally not conducive to mutual engagement, reflection, or dialogue. There is an urgent need for new dialogue formats that can better foster learning and community-building and thereby harness the enormous latent potential for climate action represented by the diverse stakeholders that gather at the COP. Against this backdrop, and drawing on our experience with the development and implementation of the Co-Creative Reflection and Dialogue Spaces at COP25, COP26, and COP27, we make recommendations for further developing the communication culture of the COPs. At the level of individual sessions, we provide recommendations for designing participatory dialogues that can better support reflection, interconnection, and action orientation. In addition, we offer guidance for scaling up these practices, for instance through networks and communities of practice to support a shift of the overall communication culture of the COPs. Our recommendations focus on interactions and exchanges that unfold outside of the formal negotiation sessions, with a view toward enabling and accelerating transformative action by non-state actors.
