Climate change, increasingly recognized as a defining challenge of our time, is exerting profound effects not only on the physical environment but also on the mental health of young people worldwide. A growing body of research from peer-reviewed studies and large-scale surveys reveals that adolescents are experiencing heightened levels of anxiety, stress, and despair linked directly to environmental uncertainty and the anticipated future threats posed by climate disruption.
Recent research, including a national survey of 800 Canadian youth aged 13 to 18 led by Athabasca University and published in October 2025, found that 37% of teens reported that climate change impacted their mental health to some degree. Teens across multiple countries similarly report emotional distress connected to climate concerns, manifesting as what is now often referred to as “climate anxiety” or “eco-anxiety.” These feelings emerge as youth process the systemic threat of climate change, including fears about their future, biodiversity loss, and the environmental legacy they will inherit .
The phenomena are observable around the globe, with surveys spanning the US, Europe, India, and beyond indicating young people’s struggle with climate-related psychological stress. The temporal context is urgent—climate anxiety and distress among youth have been documented escalating between 2021 and 2025, coinciding with intensifying global climate impacts such as wildfires, storms, and resource insecurity .
The Athabasca University study identified four major themes describing how climate change affects teen mental health:
-
Emotional symptoms including anxiety, stress, depression, sadness, and fear.
-
Concerns about personal and collective futures, including worries over homes, livelihoods, and raising children in a deteriorating environment.
-
Impacts on daily functioning such as disrupted sleep, breathing issues during wildfire smoke, headaches, and general physical symptoms linked to environmental conditions.
-
Feelings of helplessness and difficulty maintaining normal activities due to pervasive climate worries (, web:Additional data from a large-scale US survey of over 15,000 youth aged 16 to 25 revealed 43% felt their mental health was negatively affected by climate change, with 38% stating these feelings impaired their daily lives. Importantly, those exposed to more frequent climate disasters showed higher distress levels, confirming the cumulative psychological toll of repeated climate events .
Expert Commentary
Dr. Gina Martin, associate professor at Athabasca University’s Faculty of Health Disciplines, co-authored the Canadian study, emphasizing the significance of young people’s self-reported experiences. “We are seeing increased recognition of climate anxiety and eco-anxiety as real mental health issues affecting youth. Their accounts provide crucial insight into how this global crisis is shaping a generation’s emotional wellbeing”
Dr. Caroline Hickman, a psychologist specializing in climate mental health, highlights that eco-anxiety is an emotional response reflecting mental health aligned with external realities. She advocates transforming this anxiety into eco-compassion and internal activism, promoting community support and resilience-building alongside external climate action. “There is hope,” she states, “fueled by the courage and radical hope of young people who openly share their feelings and advocate for change” .
Context and Background
Climate change is more than an environmental issue; it is a psychological one. Adolescents are in a critical developmental period vulnerable to mental health challenges. The uncertainty, increased frequency of extreme weather events, and pervasive negative media coverage surrounding climate change compound typical adolescent stressors, potentially increasing rates of anxiety, depression, and other disorders such as PTSD, as documented in multiple meta-analyses.
Youth often feel ignored or dismissed when expressing their concerns, amplifying feelings of isolation. Surveys indicate up to 57% of young people feel unheard when discussing climate change, underscoring the need for open dialogues in families, schools, and communities to validate their experiences and foster coping strategies.
Implications for Public Health
The mental health impacts of climate change on youth pose significant challenges for healthcare providers, educators, and policymakers. Integrative strategies are needed to address climate anxiety through accessible mental health services, community support networks, and educational programs that enhance climate literacy and resilience.
Understanding climate anxiety as a rational response rather than pathological fear can guide empathetic care and public health messaging. Promoting youth engagement in climate action can also empower this demographic, transforming distress into motivation and communal solidarity .
While there is compelling evidence of mental health impacts linked to climate change, research is ongoing regarding the full scope and direct causal pathways. The variability of individual psychological resilience, regional climate effects, and socio-economic factors means responses can differ widely. Some experts caution the need to avoid pathologizing normal emotional reactions and advocate balanced reporting to not induce undue fear among youth .
Practical Advice for Readers
Individuals, parents, and educators can support young people by acknowledging their climate concerns, encouraging open conversation, and facilitating involvement in local sustainability initiatives. Seeking professional mental health support when feelings become overwhelming is critical. Fostering hope and community connection can mitigate the impacts of climate anxiety, helping youth navigate an uncertain world with agency and optimism.
