Summary
Megacities significantly impact global atmospheric composition and climate. Understanding these urban environmental effects is crucial as city populations grow.
Area of Science:
- Environmental Science
- Urban Climatology
- Atmospheric Chemistry
Background:
- Cities are centers of human economic activity with a long history of environmental impact.
- Urban populations now exceed rural populations, making their environmental effects critical.
- The rise of megacities amplifies environmental impacts to a global scale.
Purpose of the Study:
- To examine the environmental impacts of megacities on atmospheric composition and climate.
- To provide a comprehensive overview of scientific research on megacity environmental effects.
- To assess the influence of megacity emissions on air quality and climate.
Main Methods:
- Review of basic concepts related to urban environmental footprints.
- Discussion of various definitions and methodologies for environmental footprints.
- Synthesis of existing research on megacity impacts on atmosphere and climate.
Main Results:
- Megacity emissions demonstrably affect atmospheric composition.
- Urban environmental impacts are measurable at regional and global scales.
- Significant correlations exist between megacity growth and climate alteration.
Conclusions:
- Megacities exert a substantial influence on atmospheric composition and global climate patterns.
- Continued research is essential to mitigate the environmental consequences of megacities.
- Understanding megacity footprints is key to addressing global environmental challenges.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:50Global Climate Change
24.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
