Climate Change and Mental Health.

This JAMA Insights discusses the adverse effects of climate change on mental health and proposes solutions to help mitigate those effects.

A framework for understanding the human experience of nature through cognitive mapping.

Human behavior is a key driver of the biodiversity crisis, and addressing it requires changing individual choices and actions. Yet, the same processes that imperil biodiversity (e.g., urbanization) also alienate people from the experience of nature, eroding care for the natural world. Although averting this extinction of experience is increasingly recognized as a major contemporary conservation challenge, understanding of what constitutes nature experience remains elusive and few empirical studies have explored it directly. Most researchers have used nature interactions as a stand-in for experience, even though experience extends beyond interactions. We aimed to determine what constitutes the experience of nature and to propose a holistic, empirically derived framework that incorporates the multiple dimensions and components of the experience of nature. Using a mixed-method approach across 3 countries (the United States, Switzerland, and Israel), we conducted a multistage, conceptual content, cognitive mapping (3CM) exercise with 106 participants. This methodology included developing a prompt to capture participants' perceptions of nature experiences and subsequently refining and organizing their input into distinct components and underlying dimensions through an iterative engagement process. Beyond multisensory interactions with nature, experience of nature consisted of 2 dimensions: the circumstances in which interactions occur and the internal responses that encompass various cognitive, affective, and restorative benefits associated with nature interactions. These 3 dimensions had 33 components that occurred consistently across participants in the 3 countries. Frequently mentioned components included seeing animals, landscapes, or scenery; lack of human influence; weather conditions; relaxing, recharging; feeling good; and awe for nature. Fear and nature experienced at home were the least mentioned components. Together, our results showed that nature experience is a combination of nature interactions, circumstances, and internal responses. The emphasized components underscore the significance of offering access to extensive, less human-influenced natural spaces. This in turn can foster a profound nature experience, cultivating feelings of connectedness and care for nature.

Un marco de trabajo para entender la experiencia humana de la naturaleza a través del mapeo cognitivo Resumen El comportamiento humano es un factor clave en la crisis de la biodiversidad, por lo que abordarlo requiere cambios en las acciones y elecciones individuales. Aun así, los mismos procesos que ponen en peligro la biodiversidad (p. ej.: la urbanización) también alejan a las personas de experimentar la naturaleza, lo que disminuye el cuidado por la naturaleza. Aunque cada vez se reconoce más que evitar la extinción de las experiencias es un reto importante para la conservación, todavía no está claro qué constituye una experiencia de la naturaleza y pocos estudios empíricos lo han estudiado directamente. La mayoría de los investigadores ha usado las interacciones con la naturaleza como un sustituto para las experiencias, aunque éstas van más allá de las interacciones. Buscamos determinar qué constituye a las experiencias de la naturaleza y proponer un marco holístico y empírico que incorpore las múltiples dimensiones y componentes de la experiencia de la naturaleza. Usamos una estrategia de método mixto en tres países (EUA, Suiza e Israel) para realizar un ejercicio de un mapeo cognitivo de contenido conceptual en varias fases (3CM) con 106 participantes. Esta metodología incluyó el desarrollo de una entrada para capturar la percepción de los participantes con respecto a las experiencias de la naturaleza y con ello refinar y organizar sus contribuciones en diferentes componentes y dimensiones subyacentes por medio de un proceso iterativo de participación. Más allá de las interacciones multisensoriales con la naturaleza, las vivencias de la naturaleza consistieron en dos dimensiones: las circunstancias en las que ocurren las interacciones y las respuestas internas que engloban varios beneficios cognitivos, afectivos y restauradores asociados con las interacciones con la naturaleza. Estas dos dimensiones contaron con 33 componentes que aparecieron constantemente entre los participantes de los tres países. Con frecuencia mencionaron componentes que incluían avistamiento de animales o paisajes; la ausencia de influencia humana; las condiciones del clima; relajarse, recargarse; sentirse bien; y asombro por la naturaleza. El miedo y la naturaleza vivida en casa fueron los componentes menos mencionados. En conjunto, nuestros resultados mostraron que las vivencias de la naturaleza son una combinación de interacciones con la naturaleza, circunstancias y respuestas internas. Los componentes enfatizados resaltan la importancia de ofrecer acceso a los espacios naturales extensos con menos influencia humana. Esto a la vez puede promover una experiencia profunda de la naturaleza, lo que genera sentimientos de conexión y cuidado de la naturaleza.

Examining the mental health impacts of climate change on young people in Canada: a national cross-sectional survey.

BACKGROUND: Climate change poses a substantial threat to the mental wellbeing of young people. Population-level research is urgently needed to help inform policies and interventions to ensure that young people are not burdened by long-term mental health impacts from climate change. We sought to identify the prevalence, distribution, and factors associated with climate change-related mental and emotional health outcomes among young people (aged 13-34 years) in Canada. METHODS: This study is part of a larger cross-sectional survey, which examined mental and emotional health responses to climate change among individuals aged 13 years or older from across Canada. We used a multi-stage, multi-stratified random probability sampling procedure. Participants were randomly recruited through either an addressed letter or a telephone call. Online and telephone questionnaires were used to interview individuals in English, French, or Inuktitut between April 1, 2022, and March 31, 2023. Data were weighted by age and province using population estimates from Statistics Canada and analysed using descriptive statistics, factor analyses, and multivariable regression analyses. FINDINGS: The full survey included 2476 participants, with a subgroup of 409 young people. Of the 401 respondents who provided their gender identity, 215 (54%) identified as cisgender women, 167 (42%) identified as cisgender men, and 19 (5%) identified as non-binary. Preliminary results suggest that young people in Canada experience a wide range of climate-related emotional and mental health outcomes. More than 70% of respondents in the young people subgroup reported having at least mild levels of sadness, anger, worry, anxiety, concern, helplessness, hopelessness, or powerlessness related to climate change. The severity of climate-related emotional responses differed by gender, with non-binary respondents and cisgender women reporting higher average levels of distress than cisgender men. Regional differences were also observed, with northern regions and urban locations reporting more severe reactions. INTERPRETATION: This study builds on the understanding of the burden of climate change on the mental health of young people. If unaddressed, the impact of this burden could have long-standing and wide-reaching public health and related socioeconomic effects.

A social psychology of climate change: Progress and promise.

Social psychologists have conducted research relevant to environmental problems for many decades. However, the climate crisis presents a new problem with distinctive aspects and distinctive urgency. This paper reviews some of the principal ways in which social psychological research and theory have approached the topic, looking at perceptions, behaviour, and impacts linked to climate change. Each of these areas is becoming more sophisticated in acknowledging the diversity of experience among groups that vary in demographics and social roles. I close by identifying three important facets for future research: a focus on social justice, an effort to participate in interdisciplinary efforts, and an emphasis on maximizing our impact.

Estimating climate change and mental health impacts in Canada: A cross-sectional survey protocol.

Climate change has severe and sweeping impacts on mental health. Although research is burgeoning on mental health impacts following climate and weather extremes, less is known about how common these impacts are outside of extreme events. Existing research exploring the prevalence of psychosocial responses to climate change primarily examines university students and uses non-random sampling methods. Herein, our protocol outlines an approach to data collection, processing, and analysis to estimate the population prevalence, magnitude, and distribution of mental health responses to climate change in Canada. A cross-sectional survey of youth and adults aged 13 years and older in Canada will be administered over the course of one year. The questionnaire will take approximately 10 minutes to complete orally and will be administered in English, French, and Inuktitut. The survey will consist of six sections: (1) self-reported past experiences of climate change; (2) self-reported climate-related emotions; (3) self-reported past and current impacts, anticipatory impacts, and vicarious experiences; (4) self-reported subclinical outcomes; (5) self-reported behavioural responses; and (6) demographics. A multi-stage, multi-stratified random probability sampling method will be used to obtain a sample representative of the Canadian population. We will use two different modes of recruitment: an addressed letter sent by postal mail or a telephone call (landlines and cellular). Population-weighted descriptive statistics, principal component analysis, and weighted multivariable regression will be used to analyse the data. The results of this survey will provide the first national prevalence estimates of subclinical mental health responses to climate change outcomes of people living in Canada.

Climate change anxiety and mental health: Environmental activism as buffer.

A growing body of research has documented the phenomenon of climate change anxiety (CCA), defined broadly as negative cognitive, emotional, and behavioral responses associated with concerns about climate change. A recently validated scale of CCA indicated two subscales: cognitive emotional impairment and functional impairment (Clayton & Karazsia, 2020). However, there are few empirical studies on CCA to date and little evidence regarding whether CCA is associated with psychiatric symptoms, including symptoms of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD), and whether engaging in individual and collective action to address climate change could buffer such relationships. This mixed methods study draws on data collected from a sample of emerging adult students (ages 18-35) in the United States (N = 284) to address these gaps. Results indicated that both CCA subscales were significantly associated with GAD symptoms, while only the Functional Impairment subscale was associated with higher MDD symptoms. Moreover, engaging in collective action, but not individual action, significantly attenuated the association between CCA cognitive emotional impairment and MDD symptoms. Responses to open-ended questions asking about participants' worries and actions related to climate change indicated the severity of their worries and, for some, a perception of the insignificance of their actions relative to the enormity of climate change. These results further the field's understanding of CCA, both in general and specifically among emerging adults, and suggest the importance of creating opportunities for collective action to build sense of agency in addressing climate change.

Impacts of nature deprivations during the COVID-19 pandemic: A pre-post comparison.

Nature provides a myriad of intangible and non-material services to people. However, urbanites are increasingly disconnected from the natural world. The consequences of this progressive disconnection from nature remain difficult to measure as this process is slow and long-term monitoring or large-scale manipulation on nature experiences are scarce. Measures to contain the spread of the recent COVID-19 pandemic (i.e., lockdowns) have potentially reduced or even suppressed nature experiences in cities. This situation provided an opportunity for conducting a longitudinal study that can serve as a sort of natural experiment to quantify the effects of nature deprivation on individuals' health, well-being and relationship to nature. We collected data on these variables from the same individuals inhabiting a large metropolis (Tel Aviv, Israel) twice, in 2018 (before) and during the lockdown in 2020. Our results confirmed that frequency, duration and quality of nature interactions dropped during the lockdown, while environmental attitudes and affinity towards nature remained similar. This was particularly true for people living in the least green neighborhoods, where a significant decrease in personal and social well-being was also found. Finally, affinity towards nature influenced well-being through nature experiences in 2018. The mediation effect was not significant in 2020, probably due to the decrease in nature experiences during the lockdown, but the direct relationship between affinity towards nature and well-being remained strong. These results provide insights into the means required to align the public health and conservation agendas to safeguard urbanites' health and well-being during a pandemic and mitigate the biodiversity crisis.

Global priorities for climate change and mental health research.

BACKGROUND: Compared with other health areas, the mental health impacts of climate change have received less research attention. The literature on climate change and mental health is growing rapidly but is characterised by several limitations and research gaps. In a field where the need for designing evidence-based adaptation strategies is urgent, and research gaps are vast, implementing a broad, all-encompassing research agenda will require some strategic focus. METHODS: We followed a structured approach to prioritise future climate change and mental health research. We consulted with experts working across mental health and climate change, both within and outside of research and working in high, middle, and low-income countries, to garner consensus about the future research priorities for mental health and climate change. Experts were identified based on whether they had published work on climate change and mental health, worked in governmental and non-governmental organisations on climate change and mental health, and from the professional networks of the authors who have been active in the mental health and climate change space. RESULTS: Twenty-two experts participated from across low- and middle-income countries (n = 4) and high-income countries (n = 18). Our process identified ten key priorities for progressing research on mental health and climate change. CONCLUSION: While climate change is considered the biggest threat to global mental health in the coming century, tackling this threat could be the most significant opportunity to shape our mental health for centuries to come because of health co-benefits of transitioning to more sustainable ways of living. Research on the impacts of climate change on mental health and mental health-related systems will assist decision-makers to develop robust evidence-based mitigation and adaptation policies and plans with the potential for broad benefits to society and the environment.

Climate anxiety in children and young people and their beliefs about government responses to climate change: a global survey.

BACKGROUND: Climate change has important implications for the health and futures of children and young people, yet they have little power to limit its harm, making them vulnerable to climate anxiety. This is the first large-scale investigation of climate anxiety in children and young people globally and its relationship with perceived government response. METHODS: We surveyed 10 000 children and young people (aged 16-25 years) in ten countries (Australia, Brazil, Finland, France, India, Nigeria, Philippines, Portugal, the UK, and the USA; 1000 participants per country). Invitations to complete the survey were sent via the platform Kantar between May 18 and June 7, 2021. Data were collected on participants' thoughts and feelings about climate change, and government responses to climate change. Descriptive statistics were calculated for each aspect of climate anxiety, and Pearson's correlation analysis was done to evaluate whether climate-related distress, functioning, and negative beliefs about climate change were linked to thoughts and feelings about government response. FINDINGS: Respondents across all countries were worried about climate change (59% were very or extremely worried and 84% were at least moderately worried). More than 50% reported each of the following emotions: sad, anxious, angry, powerless, helpless, and guilty. More than 45% of respondents said their feelings about climate change negatively affected their daily life and functioning, and many reported a high number of negative thoughts about climate change (eg, 75% said that they think the future is frightening and 83% said that they think people have failed to take care of the planet). Respondents rated governmental responses to climate change negatively and reported greater feelings of betrayal than of reassurance. Climate anxiety and distress were correlated with perceived inadequate government response and associated feelings of betrayal. INTERPRETATION: Climate anxiety and dissatisfaction with government responses are widespread in children and young people in countries across the world and impact their daily functioning. A perceived failure by governments to respond to the climate crisis is associated with increased distress. There is an urgent need for further research into the emotional impact of climate change on children and young people and for governments to validate their distress by taking urgent action on climate change.

Biodiversity conservation as a promising frontier for behavioural science.

Human activities are degrading ecosystems worldwide, posing existential threats for biodiversity and humankind. Slowing and reversing this degradation will require profound and widespread changes to human behaviour. Behavioural scientists are therefore well placed to contribute intellectual leadership in this area. This Perspective aims to stimulate a marked increase in the amount and breadth of behavioural research addressing this challenge. First, we describe the importance of the biodiversity crisis for human and non-human prosperity and the central role of human behaviour in reversing this decline. Next, we discuss key gaps in our understanding of how to achieve behaviour change for biodiversity conservation and suggest how to identify key behaviour changes and actors capable of improving biodiversity outcomes. Finally, we outline the core components for building a robust evidence base and suggest priority research questions for behavioural scientists to explore in opening a new frontier of behavioural science for the benefit of nature and human wellbeing.

Ethics, morality, and the psychology of climate justice.

Climate change is increasingly understood as a social justice issue by academics, policymakers, and the public; however, the nature of these perceptions and their implications for cooperation and decision-making have only recently begun to receive empirical attention. We review emerging empirical work that suggests that morality and justice perceptions can serve as both a bridge and a barrier to cooperation around climate change and highlight two critical areas for future development, identifying psychological processes that promote and impede climate vulnerability and that enhance equity in the design and implementation of climate solutions. We argue that conceptualizing climate justice as a multidimensional process addressing both social and structural barriers can stimulate new psychological research and help align disparate approaches within the social sciences.

Climate Change and Mental Health.

PURPOSE OF REVIEW: This essay reviews evidence for the current and potential effects of climate change on mental health. RECENT FINDINGS: A growing body of research demonstrates not only that the extreme weather events associated with a changing climate can impair mental health, in particular leading to increases in depression and post-traumatic stress disorder, but also that more gradual changes in climatic conditions, such as rising temperatures and reduced air quality, are also harmful to mental health. In addition, there is increasing evidence that a significant proportion of people might be experiencing a harmful level of anxiety associated with their perception of climate change. Mental health impacts of climate change have the potential to affect a significant proportion of the population. More research is needed to document the extent of these impacts as well as the best options for mitigating and treating them.

How psychology can help limit climate change.

The Intergovernmental Panel on Climate Change has encouraged psychologists to become part of the integrated scientific effort to support the achievement of climate change targets such as keeping within 1.5°C or 2°C of global warming. To date, the typical psychological approach has been to demonstrate that specific concepts and theories can predict behaviors that contribute to or mitigate climate change. Psychologists need to go further and, in particular, show that integrating psychological concepts into feasible interventions can reduce greenhouse gas emissions far more than would be achieved without such integration. While critiquing some aspects of current approaches, we describe psychological research that is pointing the way by distinguishing different types of behavior, acknowledging sociocultural context, and collaborating with other disciplines. Engaging this challenge offers psychologists new opportunities for promoting mitigation, advancing psychological understanding, and developing better interdisciplinary interactions.

Climate anxiety: Psychological responses to climate change.

Climate change will affect psychological wellbeing. Substantial research has documented harmful impacts on physical health, mental health, and social relations from exposure to extreme weather events that are associated with climate change. Recently, attention has turned to the possible effects of climate change on mental health through emotional responses such as increased anxiety. This paper discusses the nature of climate anxiety and some evidence for its existence, and speculates about ways to address it. Although climate anxiety appears to be a real phenomenon that deserves clinical attention, it is important to distinguish between adaptive and maladaptive levels of anxiety. A focus on individual mental health should not distract attention from the societal response that is necessary to address climate change.

Psychology and climate change.

Research and theory from psychology are increasingly being utilized to understand potential impacts of climate change and to promote positive responses. In this Primer, Clayton describes three main areas in which psychological research provides relevant insights, and provides suggestions for encouraging mitigation and adaptation behavior.

Confronting the wildlife trade through public education at zoological institutions in Chengdu, P.R. China.

The wildlife trade poses substantial threats to global biodiversity. China is a significant source of threatened species and also a market for wildlife products. Zoological parks (zoos), which are a popular leisure attraction in China as elsewhere, are increasingly conceptualized as places to educate visitors about both animals and environmental threats more generally. This paper reports on an attempt to inform Chinese zoo visitors about the threats presented by the wildlife trade, and about the opportunity to take personal actions to help protect wildlife. Results from a baseline survey of attitudes among 524 adult visitors to animal exhibits in Chengdu, China showed a high degree of concern about wildlife paired with a lack of confidence about what could be done. A sense of connection to nature, along with a perception of personal efficacy, were the strongest predictors of concern about the wildlife trade. Based in part on these results, an informational exhibit was designed and implemented in two locations in Chengdu. A survey of 533 visitors to assess the impact of the new exhibit showed that connection and perceived efficacy continued to predict concern, and that talking about the exhibit was associated with increased knowledge and concern. Though causality cannot be definitively concluded, results suggest that zoos have the potential to influence attitudes and perceived norms regarding the wildlife trade. By affirming the importance of a feeling of connection, the findings indicate that animal facilities may have an important role in fostering the human relationship to the natural world.

Psychologists and the problem of population growth: Reply to Bridgeman (2017).

Bridgeman (2017) describes the important role of population growth in contributing to environmental problems. The present essay argues that population is an important component of human impact on the environment, but it must be considered in combination with consumption rates. A place-based approach, examining the local context for reproductive decisions, is necessary to assess population growth as a contributor to environmental impact and to develop appropriate behavioral interventions.

The complex relationship between personal sense of connection to animals and self-reported proenvironmental behaviors by zoo visitors.

The global biodiversity crisis requires an engaged citizenry that provides collective support for public policies and recognizes the consequences of personal consumption decisions. Understanding the factors that affect personal engagement in proenvironmental behaviors is essential for the development of actionable conservation solutions. Zoos and aquariums may be some of the only places where many people can explore their relations with wild animals and proenvironmental behaviors. Using a moderated-mediation analysis of a survey of U.S. zoo and aquarium visitors (n = 3588), we explored the relationship between the sense of connection to animals and self-reported engagement in proenvironmental behaviors related to climate change and how this relationship is affected by certainty that climate change is happening, level of concern about climate change, and perceptions of effectiveness in personally addressing climate change. We found a significant, directional relationship between sense of connection to animals and self-reported proenvironmental behaviors. Political inclination within the conservative to liberal spectrum did not affect the relationship. We conclude that a personal sense of connection to animals may provide a foundation for educational and communication strategies to enhance involvement in proenvironmental actions.

Expanding the role for psychology in addressing environmental challenges.

Environmental challenges, though daunting, present an important area for psychologists to apply their knowledge. Psychological theories, research methods, and interventions are essential for examining the questions about human impacts, tendencies, and capacities that are integral to constructing effective responses to these challenges. Although a great deal of relevant research has been done, there is scope for psychologists to be more extensively involved. Following a brief review of existing research, we outline some important new directions. We also highlight 2 key divergences, arguing that psychological research needs to expand beyond a traditional, theory-based and decontextualized approach to environmental issues to incorporate a contextualized or "place-based" approach and a willingness to collaborate in interdisciplinary research teams that focus on specific environmental problems. Suggestions for promoting such interdisciplinary collaborations are reviewed. We encourage psychologists to expand their engagement with important environmental issues through multiple research approaches in order to further their understanding of human behavior, contributions to human well-being, and relevance to other disciplines and to society.

Global climate change attitudes and perceptions among south American zoo visitors.

There is a substantial gap between the scientific evidence for anthropogenic climate change and the human response to this evidence. Perceptions of and responses to climate change can differ among regions of the world, as well as within countries. Therefore, information about the public's attitudes and perceptions related to climate change is essential to the development of relevant educational resources. In the present study, zoo visitors in four South American countries responded to a questionnaire regarding their attitudes and perceptions toward global climate change. Results indicated that most respondents are already highly concerned about global climate change and are interested in greater engagement in pro-environmental behaviors. Visitors also perceive various obstacles to engagement in climate change mitigation behaviors. We discuss the results of our study in terms of addressing visitors' climate change attitudes and perceptions within the social and emotional context of zoo settings.
