The urban environment has two atmosphere layers, besides the planetary boundary layer (PBL) outside and extending well above the city: (1) The urban boundary layer is due to the spatially integrated heat and moisture exchanges between the city and its overlying air. (2) The surface of the city corresponds to the level of the urban canopy layer.
The climate in urban areas differs from that in neighboring rural areas, as a result of urban development. Urbanization greatly changes the form of the landscape, and also produces changes in an area's air. The study of urban climate is urban climatology. In 1950 Åke Sundborg published one of the first theories on the climate of cities. [1] [2]
The ACS study correlated air pollution data, lifestyle factors, and death records for a sample of 552,138 adults in 151 urban areas followed over a 16-year period and concluded, just as the original had done, that breathing particulate pollution increases a person's risk of death: "Particulate air pollution was associated with cardiopulmonary ...
Urbanization commonly occurs in cities with low and middle income communities that have high population density and a lack of understanding of how climate change, which degrades their environment, is affecting their health. Within urban settings, multiple climate and non-climate hazards impact cities which magnify the damages done to human health.
Urban geography is the subdiscipline of geography that derives from a study of cities and urban processes. Urban geographers and urbanists [1] examine various aspects of urban life and the built environment. Scholars, activists, and the public have participated in, studied, and critiqued flows of economic and natural resources, human and non ...
Humans are the driving force behind urban ecology and influence the environment in a variety of ways - urbanization being a key example. Urbanization is tied to social, economic and environmental processes. There are six core aspects: air pollution, ecosystems, land use, biogeochemical cycles, water pollution, solid waste management, and the ...
Energy Efficiency of different Transport Modes. Sustainable urbanism is both the study of cities and the practices to build them (), that focuses on promoting their long term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place.

A study published in 2019 indicated that in 2015 the number may be closer to 8.8 million, with 5.5 million of these premature deaths due to air pollution from anthropogenic sources. [135] [136] A 2022 review concluded that in 2019 air pollution was responsible for over 6.5 million deaths. It concluded that since 2015 little real progress ...
