The profound toll of climate change on public health is not just an environmental concern; it profoundly affects economies and societies, particularly in developing nations. The immediate devastation caused by flooding and the prolonged repercussions of droughts and water scarcity lead to economic turmoil, exacerbate poverty, and pose significant threats to human health. Beyond the physical injuries and illnesses that result from such events, they also precipitate serious mental health challenges. According to the findings presented in the IPCC’s Sixth Assessment Report, extreme weather incidents severely harm mental health, heightening levels of anxiety and distress.
Every instance of extreme weather, along with any slight rise in global temperatures, amplifies the likelihood of further disease outbreaks and threatens to undo the health advancements achieved over previous decades. Vulnerable communities are often the hardest hit, facing increased mortality rates and health issues due to heatwaves, dangerously polluted air and water, and the spread of diseases transmitted by vectors, such as dengue fever. Alarmingly, it is estimated that air pollution alone contributes to approximately seven million premature deaths annually.
The World Health Organization predicts that climate change will result in an additional 250,000 deaths per year between 2030 and 2050, primarily due to factors like undernutrition, malaria, diarrhea, and heat stress. This situation is bound to worsen unless immediate and robust climate action is taken. Recent studies show that frequent exposure to severe weather conditions and ongoing climate challenges significantly correlates with a rise in mental health issues—this trend is not limited to just those already vulnerable. Anxiety and depression are particularly prevalent among individuals directly affected by climate-related disasters, as well as those displaced or facing livelihood losses.
While the entire population feels the impact, young people are especially at risk of experiencing disillusionment and anxiety as they grapple with daunting prospects of living in a climate-affected world. It is noteworthy that around 90% of the globe's 1.8 billion young people reside in countries that are highly susceptible to climate change. A study conducted in 2021 by Bath University indicated that 60% of 10,000 surveyed youths across ten countries expressed being "very worried or extremely worried" about climate change, linking chronic stress over these environmental issues to heightened risks of both mental and physical health problems. If a similar survey were to be conducted today, it is likely that the percentage of concerned youths would be even greater, given the escalation of climate-related stressors since then.
The intersection of climate change with trauma and mental health is undeniable. Pakistan serves as a stark example of a nation vulnerable to climate-related challenges, compounded by its youthful demographic. The country has faced recurrent floods and severe heatwaves, plunging it into a state of crisis characterized by the dangerous interplay between climate change, health, poverty, and rising inequality. Mental health concerns further complicate this already challenging landscape.
The devastation wrought by the floods of 2010 and 2022 left millions economically impacted, and many of these individuals are now grappling with trauma and depression. The emotional anguish experienced by those who lost loved ones or were forced to relocate to areas lacking in social support is profound. Children and adolescents suffer the longest, as their education is disrupted and essential needs like clean drinking water become unattainable. UNICEF reported that around 10 million children lacked access to clean drinking water and other vital services for over six months following the 2022 floods. While efforts were made to address their physical injuries and economic losses, little attention was directed towards their psychological healing during this critical time. A major factor contributing to this oversight is the insufficient mental health infrastructure within the public sector. With a shortage of psychiatrists and facilities, mental health remains a significant gap in the public health framework in several developing nations, including Pakistan.
Simultaneously, awareness about the connection between climate change and mental health is alarmingly low. While there is substantial documentation and evidence regarding how climate change affects health, which can aid in forming climate strategies that address physical injuries, the costs associated with trauma and psychological disorders triggered by environmental catastrophes are often overlooked when shaping climate policies.
To rectify this situation, governments must prioritize mental health by allocating resources to establish specialized mental health care facilities. The lack of adequate healthcare services in rural and peri-urban areas makes individuals more vulnerable to climate-related health issues. Discussing mental health remains a taboo in many cultures. To dismantle the stigma surrounding mental health, educational institutions, local organizations, and media should work collaboratively to raise awareness about these issues and their far-reaching implications. By emphasizing the connections between mental health and climate disasters—topics to which people can easily relate—we can foster a greater understanding. Addressing mental health, much like tackling climate change, cannot be postponed; it demands urgent attention today.
