Definition: Greenhouse Gases

Greenhouse Gases - "carbon dioxide (from coal, oil, natural gas, and deforestation), methane, nitrous oxide, water vapor, and chlorofluorocarbons injected into the atmosphere. These gases, the concentration of which is increased through vehicle and factory energy use and other human activity, change temperature, climate, and ocean circulation, and thus affect economic activity." - source: Economic Development 4th Edition by E.
