Climate and environmental risk factors have been widely identified in the literature as critical determinants of population health and disease distribution. Empirical studies consistently link rising temperatures and more frequent heat waves to increased all-cause mortality, heat-related morbidity, and exacerbation of chronic cardiovascular and respiratory conditions. Air pollution—particularly fine particulate matter (PM2.5), ozone, and nitrogen oxides—has been associated with heightened risks of asthma, chronic obstructive pulmonary disease, ischemic heart disease, stroke, and adverse perinatal outcomes. Climatic shifts also drive changes in the ecology of vectors and pathogens: warming and altered precipitation patterns expand the geographic and seasonal ranges of mosquitoes and ticks, facilitating the emergence and re-emergence of vector-borne diseases such as dengue, chikungunya, Lyme disease, and malaria.
Extreme weather events (floods, storms, droughts) produce immediate injury and mortality and longer-term impacts on mental health, displacement, and interruption of health services. Flooding and compromised sanitation increase the incidence of waterborne diseases, while drought undermines food security and nutritional status, particularly among vulnerable populations. Land-use change, deforestation, and urbanization modify exposure pathways by changing habitats, increasing human–wildlife contact, and concentrating pollutants and heat in urban “heat islands.” The literature emphasizes that environmental risks interact with socioeconomic and demographic factors: poverty, limited access to healthcare, and preexisting illness amplify vulnerability and compound inequities in climate-related health outcomes.
Research also notes non-linear relationships, threshold effects, and considerable local heterogeneity, indicating that impacts are context-specific and mediated by adaptive capacity. Recent reviews call for integrated surveillance systems, cross-sectoral mitigation and adaptation strategies, targeted interventions for high-risk groups, and improved modeling of joint climate-environment-health pathways. Gaps remain in attributing specific health outcomes to particular environmental exposures and in evaluating the effectiveness of interventions, pointing to priority areas for future research.
