INTRODUCTION: The Anthropocene is used to describe the most recent period where major disruptions in Earth's system processes have resulted from humanity's increasing ecological footprint. Climate change affects the social and environmental determinants of good health, such as clean air, stable ecosystems, safe drinking water, and sufficient and safe food, and they seem to be closely related to air pollution. OBJECTIVES: This article aims to review the evidence of how extreme weather events and indoor and outdoor pollution are associated with insufficient lung growth in early life, changes in lung function, and the increase in respiratory infections, favoring the development of allergic respiratory diseases. MATERIAL AND METHODS: Non-systematic review of English, Spanish, and Portuguese articles published in the last ten years in databases such as PubMed, EMBASE, and SciELO. The terms used were air pollution OR climate changes OR smoke, AND health OR allergic disease. RESULTS: Climate change and air pollution are the leading contributors to health emergencies around the world. On a global scale, those most at risk of adverse health effects associated with climate change include children, the elderly, and other vulnerable groups. Climate change and air pollution have adverse impacts on respiratory allergies, and the mechanisms are complex and interactive. CONCLUSION: Health professionals must receive information and education necessary to establish effective mitigation and adaptation strategies to minimize the effects of climate changes on the respiratory health of their patients.
