Investigating the effect of climate change on air pollution in metropolises

One of the most important issues related to climate today is the development of urbanization and urban air pollution, especially in metropolitan areas and subsequently urban climate. Today, air and environmental pollution has been raised as one of the problems of human society, and this is not a regional issue and is not limited to political and geographical borders, but is a global issue. Thus, one of the challenges of the 21st century is the issue of climate change. Therefore, in this study, using descriptive-analytical methods and citing sources in various ways to try to address the effects of climate change on metropolises. Based on the available findings, it can be said that climate change itself is one of the results of the increase in the emission of pollutants in metropolitan areas, which has now overshadowed all aspects of human life. At the same time, climate change can be achieved through; Global warming, increasing emissions of some major pollutants such as ozone and particulate matter, forest fires, migration, metropolitan population growth, urban health threats, inversion and the creation of thermal islands are affecting metropolitan air quality.
