Greenhouse gases (GHGs) are gases in the Earth's atmosphere that trap heat, preventing it from escaping back into space. They play a crucial role in regulating the Earth's temperature by allowing sunlight to pass through the atmosphere but trapping some of the heat re-radiating from Earth's surface.
This process is known as the greenhouse effect, which helps keep the planet warm enough to support life.
The most common greenhouse gases are:
- Carbon Dioxide (CO₂): Released by burning fossil fuels (coal, oil, gas), deforestation, and certain industrial processes.
- Methane (CH₄): Emitted from livestock, landfills, and the production and transport of coal, oil, and natural gas.
- Nitrous Oxide (NO₂): Produced by agricultural and industrial activities, as well as the combustion of fossil fuels.
- Fluorinated Gases: Synthetic gases used in industrial applications like refrigeration and air conditioning.
These gases contribute to global warming and climate change by increasing the Earth's heat retention.
