Document deals with critical issues climate change trauma and collective dissociation as significant obstacles to effective action against the climate crisis. The authors emphasize that Climate change is not just an environmental issue, but has far-reaching implications for public health and well-being, affecting physical health, mental well-being and ecological balance.

The document states that rising temperatures and more frequent extreme weather events they have an impact on physical health while also leading to traumatic reactions and dissociation as coping mechanisms. Vulnerable communities are disproportionately affected, especially in the area of food security. Climate disasters have profound and lasting effects on mental health, contributing to anxiety, depression, PTSD, increased suicide rates and substance use.

It is created "climate change trauma", which, unlike traditional trauma, which is usually experienced at an individual level, affects entire communities and societies. This phenomenon leads to collective dissociation, which is a subconscious defense mechanism against the overwhelming global trauma caused by the disasters triggered by the climate crisis. Collective dissociation manifests itself as fragmentation, polarization, and dissociation within cultures and societies. When anxiety and stress turn into denial, especially “collective dissociation,” it significantly affects the perception and conceptualization of the climate crisis.

The authors claim that The climate crisis is fundamentally a crisis of relationships, the disruption of natural systems is in parallel disrupting social and psychological systems, creating a profound relational crisis between people and the planet, as well as within communities around the world. The existential threat that climate change poses to global biodiversity and shared identity deeply affects the human mind. Feelings of helplessness and hopelessness are widespread traumatic reactions.

Collective dissociation threatens the cooperation needed to address climate change. Fragmentation of emotional complexities hinders integrated and adaptive responses, reinforces isolation, and prevents objective assessment of the devastating reality of climate change. The consequence is the continuation of harmful environmental practices. Collective dissociation affects all levels of society, leading to social alienation and political apathy, which hinders meaningful climate action.

The document emphasizes that The psychological impact of climate change is a significant obstacle to proactive climate action. Feelings of helplessness in the face of the scale and complexity of the problem lead to feelings of futility and may manifest as sleep disturbances and increased anxiety. Defense mechanisms such as denial are activated to cope with existential fears. Terror coping theory explains that reminders of mortality lead to psychological defenses that, in the context of climate change, hinder environmentalism.

Nevertheless, the authors point out that The relationship between the mind and climate change is not linear. and inaction on climate action is influenced by psychological, social, cultural and political dynamics. Dissociation is just one of many psychological responses, including denial, fear and misinformation.

For overcoming collective dissociation and facilitating effective collective action The document proposes several strategies:

• Responsible information management for defense: Advocacy narratives must balance individual responsibility with the roles of corporations, industries, and political structures. The emphasis should be on systemic change and accountability of larger actors. It is important to support vulnerable populations and spread messages of courage and proactivity, avoiding scaremongering. Highlighting successful examples of community initiatives can inspire broader participation.
• Local moral support: It is essential for supporting sustainable adaptation strategies and community resilience. Promoting community awareness and participation at the local level increases capacity and mental preparedness for climate action. Building capacity within local communities, engaging the community, and creating safe public spaces for discussion and support are important.
• Strategic policy development: Policymakers must view climate change as a global crisis and prioritize the mental health impacts of trauma caused by climate stressors. It is essential to mainstream climate action across sectors, allocate sufficient financial resources, and make mental health resilience a cornerstone of climate strategies. Policy should address the systemic forces that perpetuate the crisis and hold corporations and governments accountable. Education and awareness campaigns about the mental health impacts of climate change are also important.
• Research on processing climate trauma: The growing body of research on climate trauma and collective dissociation provides a critical foundation for understanding the sociological and psychological dimensions of climate change. Research should focus on the interrelationships between psychological distance, denial, and resilience, as well as the influence of ideology on responses to climate change. Collaboration between psychologists, therapists, scientists, environmentalists, and activists is key.

Finally, the document emphasizes that collective dissociation hinders effective climate action. Addressing the mental health impacts of climate change and understanding the collective trauma response are essential to creating a safer climate. Proactively addressing these psychological consequences through research, advocacy, policy development, and collaboration is key to mitigating the impact of collective dissociation on health care systems and achieving a more resilient and sustainable future.
