Greenhouse gases (GHGs) trap the infrared radiation coming from the Sun and prevent it from escaping to outer space They reradiate it back to Earth's atmosphere They are responsible for increasing the temperature of the atmosphere Carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), Ozone (O 3 ), and chlorofluorocarbons (CFCs), along with water vapour are knownSome greenhouse gases occur naturally and enter the atmosphere as a result of both natural processes (such as decomposition of organic matter) and human activity (such as burning fossil fuels and agriculture) Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO 2),"Dumping greenhouse gases into the atmosphere makes the atmosphere more humid And since water vapor is itself a greenhouse gas, the increase in humidity amplifies the warming from carbon dioxide" Specifically, the team found that if Earth warms 18 degrees Fahrenheit, the associated increase
