What do we mean when we say climate change is urgent?
Recent discussions of climate change in multiple domains—the academic literature, the popular press, political movements, and international climate policy regime—have increasingly framed the phenomenon as a “crisis,” an “emergency,” or an “urgent” situation. In this paper, we contextualize the time pressure of climate change in the broader social science literature, perform bibliometric and discourse analyses of this framing, and explore potential implications of this trend for climate decision making.
While the increased prevalence of time pressure terms is arguably part and parcel of modernity, these terms are in general not synonymous. In the context of climate decision making, we find that “urgency” functions as a boundary object relaying the internalization of time pressure between (1) the academic literature and the international climate change policy regime and (2) political movements and the popular press; especially as construed in these latter domains, “crisis” and “emergency” connote time pressure but so too generate a constellation of other affective and cognitive states. A review of a set of related literatures suggests that the time pressure framing of climate change affects the quantity and quality of information and the range of options (e.g., geoengineering) considered in choice processes for mitigation and adaptation actions, as well as the sequencing and timing of chosen plan elements; furthermore, these effects likely vary in both direction and magnitude with characteristics of the individuals or organizations in which they manifest. Taken as a whole, the crisis framing of climate change is likely to polarize beliefs and actions, especially in the absence of accompanying information about self-efficacy and hope
Halo Coronal Mass Ejections: Comparing Observations and Models
Since 1996, the SOHO LASCO coronagraphs have detected "halo" CMEs that appear to be directed toward Earth, but information about the size and speed of these events seen face-on has been limited. From a single vantage point along the Sun-Earth line, the primary limitation has been ambiguity in fitting the cone model (or other forward-modeling techniques, e.g., Thernisian et al., 2006). But in the past few years, the STEREO mission has provided a view of Earth-directed events from the side. These events offer the opportunity to compare measurements (width and speed) of halo CMEs observed by STEREO with models that derive halo CME properties. We report here results of such a comparison on a large sample of LASCO CMEs in the STEREO era
Climate Decision-Making
Climate change decision-making has emerged in recent decades as an area of research and practice, expanding on an earlier focus on climate policy. Defined as the study of decisions relevant for climate change, it draws on developments in decision science, particularly advances in the study of cognitive and deliberative processes in individuals and organizations. The effects of climate, economic, social, and other framings on decision-making have been studied, often showing that nonclimate frames can be as effective as, or more effective than, climate frames in promoting decision-making and action. The concept of urgency, linked to the ideas of climate crisis and climate emergency, has taken on importance in recent years. Research on climate decision-making has influenced numerous areas of climate action, including nudges and other behavioral interventions, corporate social responsibility, and Indigenous decision-making. Areas of transformational change, such as strategic retreat in the face of sea-level rise, are emerging
Enhanced Emission Using Thin Li-Halide Cathodic Interlayers for Improved Injection into Poly(p-phenylene vinylene) Derivative PLEDs
In this study, the effects of thin Li-halide cathodic interlayers on electron injection were examined for electroluminescent layers of polymer light-emitting diodes (PLEDs). An order of magnitude increase in current density is observed as Li-halide salts are varied down the group VII column of the periodic table. When considering luminance, devices with a LiCl interlayer were 2.3× greater than those with LiF, whereas devices with LiBr were 2.8× greater, while concurrently lowering the turn-on voltage. This resulting enhanced current density and subsequent luminance could be due to a lowered work-function difference at the cathode created by either the Li-halides dissociation-induced doping of the polymer surface or an interfacial dipole of ionic Li-halide compound, leading to band bending

The existential risk space of climate change
Climate change is widely recognized as a major risk to societies and natural ecosystems but the high end of the risk, i.e., where risks become existential, is poorly framed, defined, and analyzed in the scientific literature. This gap is at odds with the fundamental relevance of existential risks for humanity, and it also limits the ability of scientific communities to engage with emerging debates and narratives about the existential dimension of climate change that have recently gained considerable traction. This paper intends to address this gap by scoping and defining existential risks related to climate change. We first review the context of existential risks and climate change, drawing on research in fields on global catastrophic risks, and on key risks and the so-called Reasons for Concern in the reports of the Intergovernmental Panel on Climate Change. We also consider how existential risks are framed in the civil society climate movement as well as what can be learned in this respect from the COVID-19 crisis. To better frame existential risks in the context of climate change, we propose to define them as those risks that threaten the existence of a subject, where this subject can be an individual person, a community, or nation state or humanity. The threat to their existence is defined by two levels of severity: conditions that threaten (1) survival and (2) basic human needs. A third level, well-being, is commonly not part of the space of existential risks. Our definition covers a range of different scales, which leads us into further defining six analytical dimensions: physical and social processes involved, systems affected, magnitude, spatial scale, timing, and probability of occurrence. In conclusion, we suggest that a clearer and more precise definition and framing of existential risks of climate change such as we offer here facilitates scientific analysis as well societal and political discourse and action
Framing climate change in frontline communities: anthropological insights on how mountain dwellers in the USA, Peru, and Italy adapt to glacier retreat
We report on anthropological research conducted in three mountain communities (in the USA, Italy and Peru), which have been directly affected by glacier retreat for over 40 years. Our mixed methods include ethnographic research, analysis of transcripts of interviews, focus groups and community meetings, and case studies of adaptation projects. Our findings indicate that local people are acute observers of change. They draw on two frames (climate change and community) in their discussions and projects but rely much more heavily on the latter frame. This pattern of drawing on the community frame, characteristic of all discussions, is most marked in the community meetings. The effectiveness of the community frame in supporting projects calls into question some widely shared notions about the role of belief in climate change as a crucial precondition for adaptation and challenges the “perceive–predict–act” model of climate change response

Understanding subjective well-being: perspectives from psychology and public health
Background
Individual subjective well-being (SWB) is essential for creating and maintaining healthy, productive societies. The literature on SWB is vast and dispersed across multiple disciplines. However, few reviews have summarized the theoretical and empirical tenets of SWB literature across disciplinary boundaries.
Methods
We cataloged and consolidated SWB-related theories and empirical evidence from the fields of psychology and public health using a combination of online catalogs of scholarly articles and online search engines to retrieve relevant articles. For both theories and determinants/correlates of SWB, PubMed, PsychINFO, and Google Scholar were used to obtain relevant articles. Articles for the review were screened for relevance, varied perspectives, journal impact, geographic location of study, and topicality. A core theme of SWB empirical literature was the identification of SWB determinants/correlates, and over 100 research articles were reviewed and summarized for this review.
Results
We found that SWB theories can be classified into four groups: fulfillment and engagement theories, personal orientation theories, evaluative theories, and emotional theories. A critical analysis of the conflicts and overlaps between these theories reveals the lack of a coherent theoretical and methodological framework that would make empirical research systematically comparable. We found that determinants/correlates of SWB can be grouped into seven broad categories: basic demographics, socioeconomic status, health and functioning, personality, social support, religion and culture, and geography and infrastructure. However, these are rarely studied consistently or used to test theories.
Conclusions
The lack of a clear, unifying theoretical basis for categorizing and comparing empirical studies can potentially be overcome using an operationalizable criterion that focuses on the dimension of SWB studied, measure of SWB used, design of the study, study population, and types of determinants and correlates. From our review of the empirical literature on SWB, we found that the seven categories of determinants/correlates identified may potentially be used to improve the link between theory and empirical research, and that the overlap in the determinant/correlates as they relate to multiple theory categories may enable us to test theories in unison. However, doing so in the future would require a conscious effort by researchers in several areas, which are discussed
Politicizing vulnerability and adaptation: on the need to democratize local responses to climate impacts in developing countries
Exploring the value-action gap through shared values, capabilities and deforestation behaviours in Guatemala
Understanding drivers of deforestation is essential for developing any successful intervention to reduce forest degradation or loss, yet there remains relatively little consensus or clarity on how drivers should be identified and classified. To capture the full range of values and mediating factors that may contribute to land use behaviours, an approach derived from a shared values perspective that includes a range of values associated with whole landscapes and ecosystems is required. We developed a model that combines behavioural theory with the Capability Approach as a conceptual framework through which to investigate the value-action gap. We used exploratory factor analysis of Likert scale responses to belief statements to identify land-users’ shared values in the Sarstun-Motagua region of Guatemala. We then qualify and quantify the role of capabilities in mediating between the shared values of different cultural groups of land users (Q'eqchi Maya and Ladinos) by comparing their factor scores with their self-reported forest cover change behaviours. Our results indicate that Maya and Ladinos share a set of values, but hold different value orientations that predict their behavioural intentions. We find that their different value orientations reflect behavioural intentions, but an understanding of the capabilities available to different groups is also necessary to fill the value-action gap. These findings have implications for behavioural theory, providing empirical links between shared values, capabilities and behaviour and identification of the role of value orientations, as well as demonstrating a useful approach for decision makers seeking to understand drivers of change at landscape and whole ecosystem levels
