چکیده:
The term greenhouse effect describes the role of certain atmospheric gases (such as carbon dioxide, water vapor, methane, and others) in trapping heat that radiates from Earth’s surface after it has been heated by the Sun. The term greenhouse effect compares these atmospheric gases to the glass panels of a greenhouse, which lets sunlight in, isolates warm air, and impedes the loss of heat. Although the greenhouse effect is a natural and beneficial process, it has gotten a bad name because greenhouse gases, especially carbon dioxide and methane, are increasing as a result of human activities and causing global warming. Human activities that magnify the greenhouse effect and cause global warming include burning petroleum (gasoline and diesel fuel) for transportation, industrialized agriculture (a major source of methane), burning household bio fuels (wood and dung), and deforestation (to clear land for agriculture), all of which release heat-trapping gases into the atmosphere.
