Main Greenhouse Gases

Methane (CH4): Methane is another significant greenhouse gas that is released during the production and transport of coal, oil, and natural gas. It is also emitted by livestock and other agricultural practices, as well as the decay of organic waste in landfills. Methane has a much higher warming potential than carbon dioxide, although it persists in the atmosphere for a shorter period of time.

Nitrous Oxide (N2O): Nitrous oxide is primarily emitted through agricultural and industrial activities, as well as the combustion of fossil fuels and solid waste. It is also released naturally by biological processes in soils and oceans. Nitrous oxide has a warming potential several times greater than carbon dioxide and can remain in the atmosphere for over a century.

Fluorinated Gases: Fluorinated gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), are synthetic gases used in various industrial applications. They are extremely potent greenhouse gases, with warming potentials thousands of times greater than carbon dioxide. Although they are present in much smaller quantities, their long atmospheric lifetimes make them significant contributors to climate change.

Ozone (O3): While ozone is not directly emitted as a greenhouse gas, it plays a crucial role in the Earth’s atmosphere. Ozone in the stratosphere acts as a protective layer, absorbing harmful ultraviolet (UV) radiation from the sun. However, at ground level, ozone is a greenhouse gas and a pollutant, formed through complex chemical reactions involving other pollutants such as nitrogen oxides and volatile organic compounds.

Water Vapor: Water vapor is the most abundant greenhouse gas in the Earth’s atmosphere, but its concentration is highly variable and dependent on temperature and other factors. While human activities do not directly emit water vapor, they can indirectly influence its levels through the emission of other greenhouse gases. Water vapor acts as a positive feedback mechanism, amplifying the warming effect of other greenhouse gases.
