Detailed explanation-1: -Water vapor is Earth’s most abundant greenhouse gas. It’s responsible for about half of Earth’s greenhouse effect-the process that occurs when gases in Earth’s atmosphere trap the Sun’s heat.
Detailed explanation-2: -Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3).
Detailed explanation-3: -Notes. CO2 accounts for about 76 percent of total greenhouse gas emissions. Methane, primarily from agriculture, contributes 16 percent of greenhouse gas emissions and nitrous oxide, mostly from industry and agriculture, contributes 6 percent to global emissions.
Detailed explanation-4: -Carbon dioxide (CO2) Methane. Nitrous oxide. Water vapour.
Detailed explanation-5: -hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) sulphur hexafluoride (SF6) nitrogen trifluoride (NF3) 10-Nov-2016
