The Global Climate Crisis and Its Impact on Public Health

The global climate crisis is a serious threat that not only impacts the environment, but also public health. Increasing global temperatures, extreme weather and decreasing air quality are some of the problems that arise due to climate change. These impacts pose significant health risks to populations worldwide. Climate change causes an increase in the frequency of natural disasters such as floods and droughts. These disasters can cause injuries, deaths and damage to health infrastructure. In addition, they also influence access to health services. In emergency situations, health facilities may be limited, complicating the response to infectious disease outbreaks. Higher temperatures are also associated with an increase in respiratory illnesses. Air pollution produced by greenhouse gas emissions can worsen health conditions, especially for individuals with chronic diseases such as asthma and chronic obstructive pulmonary disease (COPD). Data shows that approximately 4.2 million global deaths each year are caused by outdoor air pollution, which is worsening due to climate change. The climate crisis is also exacerbating the spread of infectious diseases. For example, changes in temperature can expand the habitat of mosquitoes that carry diseases such as malaria and dengue. Research shows that previously non-remote areas are starting to face epidemics of this disease. If steps are not taken, more people are at risk of infection as a result of vector migration. Additionally, the climate crisis has psychological effects that should not be ignored. Environmental anxiety, post-disaster stress, and shifts in lifestyle, cause mental health disorders. Studies show that individuals who experience climate-related disasters can develop symptoms of PTSD (Post-Traumatic Stress Disorder). In the context of food security, the climate crisis threatens agricultural production. Unpredictable changes in rainfall patterns and temperatures can affect agricultural yields, which in turn can lead to malnutrition. Malnutrition greatly affects vulnerable groups such as children and pregnant women, resulting in long-term impacts on physical and intellectual development. The global climate crisis is also triggering international migration. People experiencing the direct impacts of environmental change are forced to leave their homes, often to areas that are not ready to accept immigrants. Population increases in certain areas can place pressure on health systems, limiting capacity to provide adequate services. To address the impact of the climate crisis on public health, collaboration between governments, health organizations and civil society is essential. Research-based interventions, public education, and the development of health policies focused on mitigation and adaptation are needed to effectively address these challenges. Identifying and prioritizing environmental health in the sustainable development agenda could be a crucial first step. Optimizing resource use, improving health infrastructure, and strengthening emission mitigation policies can help reduce the negative impact of the climate crisis on public health.
