Definition - What does Greenhouse Gases mean?
Greenhouse Gases are gases that absorb infrared radiations and trap heat in the atmosphere. There are many chemical compounds found within earth’s atmosphere that act as Greenhouse Gases. The presence of these gases allows resistance free entrance of sunlight; however, when sunlight strikes the surface, partial infrared radiations are reflected back into space and the remaining infrared radiations are trapped in the atmosphere which causes the increase in the temperature of the earth.
Petropedia explains Greenhouse Gases
Greenhouse Gases are responsible for the increase in the temperature of earth and depleting the ozone layer. These gases include:
- Carbon Dioxide (CO2) – Carbon dioxide is produced by burning wood, solid waste and fossil fuels such as crude oil, natural gas, and coal. Trees help in reducing carbon dioxide from the atmosphere by absorbing it.
- Methane (CH4) – Natural gas is 95% methane and thus, burning more natural gas increases carbon dioxide emissions thereby resulting in the increase in the carbon dioxide percentage.
- Nitrous Oxide (N2O) – Nitrous oxide is emitted during the combustion of fossil fuels and industrial activities.
- Fluorinated gases – Many industrial processes produce fluorinated gases such as hydrofluorocarbons, sulfur hexafluoride, perfluorocarbons and nitrogen trifluoride which act as synthetic greenhouse gases.
