Gases in Earth’s atmosphere that trap heat and keep the planet warm by absorbing and re-emitting infrared radiation.

The natural process where greenhouse gases trap heat from the Sun, warming Earth’s surface and atmosphere.

The long-term average pattern of weather in a region, including temperature, rainfall, and seasons.

Refers to people and human activities that can influence the environment and climate.

The overall long-term behavior of Earth’s atmosphere, especially changes in temperature and precipitation over decades or longer.

The process by which gases or surfaces take in heat energy rather than reflecting it.

The warming of Earth’s atmosphere caused by absorbed solar radiation and trapped heat.

A gas form of water and the most abundant greenhouse gas; it amplifies warming by trapping heat.

Carbon dioxide (CO₂)

A greenhouse gas released mainly from burning fossil fuels, respiration, and deforestation; a major contributor to climate change.

A powerful greenhouse gas released from livestock, landfills, natural gas leaks, and wetlands.

Nitrous oxide (N₂O)

A greenhouse gas emitted from agricultural practices, especially fertilizer use, and industrial processes.

Hydrochlorofluorocarbons (HCFCs)

Man-made gases once used as refrigerants; they are greenhouse gases and also damage the ozone layer.

Hydrofluorocarbons (HFCs)

Synthetic greenhouse gases used in refrigeration and air conditioning; they do not harm ozone but strongly trap heat.

A gas that absorbs ultraviolet radiation in the upper atmosphere but acts as a greenhouse gas near Earth’s surface.

The combustion of coal, oil, and natural gas to produce energy, releasing greenhouse gases like CO₂.

A chemical used in cooling systems (refrigerators, air conditioners) that can be a strong greenhouse gas if released.

The biological process where living organisms release carbon dioxide by breathing.

Fires caused by natural events like lightning that release carbon dioxide and other gases into the atmosphere.

The release of gases or particles into the air, often from human activities like transportation and industry.

A measure of how hot or cold something is, often used to track climate change.

Any form of water falling from the atmosphere, such as rain, snow, sleet, or hail.

Agriculture practices

Farming methods that can affect climate, such as fertilizer use, livestock raising, and land clearing.

Natural events where volcanoes release ash and gases; they can temporarily cool or warm Earth’s climate.
