Definition

Greenhouse gases (GHGs) are gases present in the Earth’s atmosphere that have the property of trapping heat (infrared radiation) from the sun and preventing it from escaping back into space. This process, known as the greenhouse effect, is essential for maintaining the planet’s temperature within a range that is suitable for life. However, an excess of greenhouse gases can enhance this effect, leading to global warming and climate change. (example – Water vapor (H2O), Carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Ozone (O3), Chlorofluorocarbons (CFCs and HCFCs), Hydrofluorocarbons (HFCs), Perfluorocarbons (CF4, C2F6, etc.), SF6, and NF3)
