Carbon dioxide is the primary greenhouse gas emitted by human activities, primarily through the burning of fossil fuels.

Air pollution contributes to climate change by releasing greenhouse gases, reducing the Earth's albedo, and increasing the Earth's surface temperature.

Black carbon is a major contributor to both air pollution and climate change. It is emitted from diesel engines, power plants, and other sources, and it can contribute to respiratory problems and cardiovascular disease.

Transboundary air pollution is the term used to describe the phenomenon where air pollution is transported long distances by wind and deposited in other areas.

Agriculture, landfills, and natural gas production are all major sources of methane emissions.

Air quality inversion is the term used to describe the phenomenon where ground-level ozone and other air pollutants are trapped near the Earth's surface by a layer of warm air.

Acid rain is primarily caused by sulfur dioxide (SO₂) emissions from power plants and industrial facilities.

Motor vehicles, power plants, and industrial facilities are all major sources of nitrogen dioxide (NO₂) emissions.

Smog is the term used to describe the phenomenon where air pollution is concentrated in a particular area due to geographic or meteorological factors.

Motor vehicles are the major source of carbon monoxide (CO) emissions.
