Airborne contaminants and global warming are both of the leading severe and interrelated environmental issues impacting people worldwide in the 21st century. Together, these factors have a significant effect on healthy ecosystems, ecological sustainability, human well-being, and especially impact on vulnerable communities in developed as well as developing nations. Human-caused processes such as burning of fossil fuels, industrial development, urbanization, transport and agricultural methods have resulted in a substantial rise in atmospheric levels of particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), carbon monoxide (CO), volatile organic compounds (VOCs) and black carbon. Around a comparable time, climate change influences weather trends due to higher temperatures, different patterns of rainfall, enhanced atmospheric equilibrium, burning forests, and severe thunderstorms, all of which affect the production, transportation and scattering of harmful substances, and the human inhalation of these substances. This article critically examines the connections among air pollution, global warming, human contact, health effects, and government policies. It covers the main sources of atmospheric pollutants, routes of exposure, biological systems, and the effects of air pollutants on pulmonary, cardiovascular, nervous system, metabolism, reproduction, and psychological health, cancer, and premature death. It also assesses the effect of airborne pollutants on DALYs, YLL and shortfalls in life cycle, along with health disparities in various regions and socioeconomic categories. This article also discusses how global warming can worsen airborne pollutants episodes due to enhanced photochemical ozone synthesis, wildfire emission levels, urban heat island phenomenon, and changes in airflow. The success rate, difficulties with implementation, and potential outcomes of various national and international policy proposals, such as the World Health Organization's (WHO) air quality standards, the UN Sustainable Development Goals (SDGs), Paris Agreement, as well as India's National Clean Air Program (NCAP) were assessed critically. Technological advances including satellite-based remote sensing; cost-effective network sensors, AI, machine learning, and high-level precision health care are introduced as revolutionary instruments for risk assessment and ecological governance. Strengthening multidisciplinary studies, expanding long-term exposure observation, improving surveillance frameworks, and implementing scientifically supported environmental regulations are critical to reducing disease burdens and building adaptability to global warming. A coordinated worldwide approach of atmospheric science, epidemiological research, public health and environmental policies will be required to achieve sustainable progress and protect subsequent generations.
