In the past, humanity’s role in accelerating climate change was often underestimated. Many people considered climate change to be merely a natural trend that came and went, unrelated to human activity. However, as research and discussion among scientists progressed, that view gradually changed. Researchers have finally reached a consensus that human activities, ranging from the exploitation of nature to industrial emissions, have disrupted the Earth’s natural balance and contributed to the rate of climate change. Various studies also show that changes in natural processes not only affect ecosystems but also influence people’s behaviour and health. With the development of social sciences and psychology, it is now increasingly clear that climate change shapes the way humans behave and act. The impact is widespread, not only in terms of natural disasters, extreme weather, or disease outbreaks, but also in terms of socio-economic changes and demographic patterns.
The relationship between humans and climate change is actually very close. Daily activities such as the use of motor vehicles, industrial activities, and energy consumption produce harmful emissions that can damage the ozone layer, which protects the earth from ultraviolet radiation. On the other hand, climate change also shapes human behaviour, influencing social norms, attitudes, and even our habits. Psychological factors such as stress and tension caused by environmental pressures also contribute to these behavioural changes.
Furthermore, climate change can shift customs, attitudes, and norms that have long been the foundation of social relations. Research shows that global warming, which has been largely triggered by human activity since the 20th century, will have an impact on the social bonds that have united communities. Rising temperatures, for example, can trigger emotional reactions in the form of increased aggression and impulsive behaviour. If these conditions continue, changes in character and a surge in violence are highly likely. In the long term, this increase in aggression could even trigger conflict and war.
Climate change is now one of the greatest challenges to human life. Its impact on living creatures and vulnerable communities is increasingly becoming the focus of researchers in various fields. We have seen how rising temperatures, heat waves, floods, tornadoes, storms, droughts, forest fires, glaciers, and the disappearance of rivers and desertification processes have had serious effects. All of these phenomena can trigger health problems, both physical and mental, either directly or indirectly.
The impacts of climate change can manifest in many ways, some of which are immediately apparent, while others only become apparent over time. The effects can also be short-term or long-term. Sudden extreme events often trigger psychological responses similar to traumatic stress, thereby influencing well-known patterns of mental disorders. On the other hand, repeated or prolonged exposure to extreme weather can also have delayed consequences, ranging from post-traumatic stress to psychological disorders that can affect future generations.
So far, climate change has often been described as an issue that increasingly shows that humans are not immune to its threats. Physical health, for example, can be affected by rising temperatures, the spread of waterborne and insect-borne diseases, and the risk of malnutrition. Not to mention the direct effects of natural disasters and the social impacts that arise from forced displacement and conflicts triggered by environmental conditions. Some groups are even more vulnerable due to high exposure levels, limited economic or political power, or specific physiological conditions, such as indigenous peoples, the elderly, children, and individuals with pre-existing health problems.
Climate change is not only an environmental issue; it also has a major impact on human psychology. Although psychologists have been researching this issue for quite some time, most of their attention has been focused on matters such as risk perception, communication strategies regarding climate change, public attitudes towards the issue, and efforts to encourage environmentally friendly behaviour as a form of mitigation. Meanwhile, the mental health aspects related to climate change have only begun to receive attention in recent years, even though their impact continues to show a significant increase.
Mental health and climate change are interconnected through many complex pathways. To clearly see the hidden costs of climate change on psychological conditions and emotional well-being, as well as to uncover the often overlooked benefits of climate action, interdisciplinary work and a more comprehensive understanding are needed. By recognising the common root causes of climate challenges and mental health issues, and then designing joint solutions that benefit both humans and the planet, policymakers, health system leaders, and mental health professionals can build stronger systems and communities to cope with global pressures in the Anthropocene era.
The climate crisis must also be understood as a mental health crisis. Climate change hinders various efforts to improve psychological well-being around the world. Its impact manifests through direct experiences of extreme temperatures and unpredictable weather, prolonged disruption to various determinants of mental health, and psychological pressure from living under an existential threat that is not being taken seriously by leaders. As a risk multiplier, this situation exacerbates existing vulnerabilities, especially for groups and countries that are already disadvantaged.
Various conditions create these inequalities, such as weak governance, social and economic disparities, a culture of natural resource exploitation, and air pollution and ecosystem damage due to the use of fossil fuels. Ironically, these factors not only worsen mental health, but are also the root causes of the same problems that continue to fuel the climate crisis.
Ultimately, climate change is no longer just an environmental issue; it is a crisis that permeates the psychological realm and human well-being. Amid growing global awareness of the importance of mental health, the climate emergency has become a major threat that could hinder this progress. Rising temperatures, extreme weather, uncertainty about the future, and the pressure of living under an existential threat that leaders have failed to resolve all create a real mental burden. The impact is felt most severely by groups that were already vulnerable to begin with. Interestingly, the root causes are interrelated: social injustice, poor governance, and an extractive culture that damages the environment—all factors that exacerbate the climate crisis also contribute to the deterioration of mental health. Ultimately, addressing the climate crisis means fighting for our collective mental health.
