Water vapor is the most abundant greenhouse gas in the atmosphere.
What are greenhouse gases?
Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and fluorinated gases are examples of greenhouse gases. The sun's light can reach Earth's surface by greenhouse gases, which then trap the heat that is reflected back from the surface inside Earth's atmosphere.
- The second most abundant greenhouse gas is carbon dioxide.
- After carbon dioxide (CO2), methane is the second most prevalent GHG produced by humans and makes for roughly 20% of world emissions. Methane has a heat-trapping capacity more than 25 times greater than carbon dioxide.
- After methane and carbon dioxide, nitrous oxide, sometimes referred to as "laughing gas," is the most significant greenhouse gas. It also poses the greatest damage to the ozone layer due to human activity.
