Question:- Which greenhouse gas is created by humans exclusively?

Answer

No gas that is emitted as a greenhouse gas comes only from people CO2, CH4, N2O and fluorinated gases are the main green house gases which are emitted from natural and anthropogenic sources in equal proportion.

The variations in the concentration levels of these gases are largely as a result of human interference such as burning of fossil fuels, agricultural activities, and industrial processes; but they also have natural causes. For instance, CO2 is produced naturally in such a way as through volcanic activities, plant and animal respiration and interaction between the ocean and atmosphere. It is obtained in different natural ways including from the swamps, termites and other geological processes. Chlorofluorocarbons (CFCs) hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs) are some of the most popular halocarbons known in society. It is widely used in refrigeration, air conditioning, production of foam as solvents or in other processes that require liquid chemicals. Halocarbons are emitted into the atmosphere in small amounts but possess higher GWP than other GHGs they therefore play a role in climate change.
