GHG, also known as Greenhouse gases, is a gas that provides to the greenhouse effect by engaging infrared radiation. Primary gases in Earth's atmosphere in H20 (water vapor) and CO2 (Carbon Dioxide). It is the leading cause of global warming and is mainly produced by natural methods like respiration and burning fossil fuels.
These burning fossil fuels create enormous amounts of CO2, which is greenhouse gases. Greenhouse Gases such as chlorofluorocarbons, methane, and nitrous oxide, will accompany CO2, changing the structure of the atmosphere and are continuing to the greenhouse effect
