Water vapor is a natural component of the atmosphere and does not directly contribute to climate change.

Air pollution, particularly greenhouse gases like carbon dioxide and methane, trap heat in the atmosphere, leading to the greenhouse effect and global warming.

Nitrogen oxides react with sunlight to form smog, which is a mixture of ground-level ozone and other pollutants.

Air pollution can cause a variety of health problems, including respiratory problems, heart disease, and cancer.

Long-range transport is the process by which air pollution is carried long distances through the atmosphere by wind currents.

Nitrogen is not a greenhouse gas because it does not trap heat in the atmosphere.

Transportation is the primary source of carbon dioxide emissions, accounting for about 29% of global emissions.

Air pollution, particularly greenhouse gases like carbon dioxide and methane, trap heat in the atmosphere, leading to the greenhouse effect and global warming.

Global warming is the term for the phenomenon in which the Earth's atmosphere is becoming warmer due to the accumulation of greenhouse gases.

Increased agricultural productivity is not a consequence of climate change. In fact, climate change is expected to have a negative impact on agricultural productivity.

Deposition is the process by which air pollution is removed from the atmosphere and deposited on the ground or water.

Sulfur dioxide is a major contributor to acid rain because it reacts with water vapor in the atmosphere to form sulfuric acid.

Global dimming is the term for the phenomenon in which the Earth's atmosphere is becoming more transparent to incoming solar radiation due to the reduction of air pollution.

Increasing the use of fossil fuels is not a strategy to reduce air pollution and mitigate climate change because fossil fuels emit greenhouse gases when burned.

The Paris Agreement is the international agreement that aims to reduce greenhouse gas emissions and mitigate climate change.
