H2O (Water vapor) ~5% --- accounts for about 72% of the greenhouse effect
CO2 (Carbon Dioxide) ~0.038 % --- accounts for about 15% of the greenhouse effect
CH4 (methane) ~0.00175 --- accounts for about 7% of the greenhouse
O3 (Ozone) --- accounts for about 5% of the greenhouse effect
The rest of the gases listed below
make up pretty much all the rest of the greenhouse effect:
N2O (nitrous oxide) ~0.00031 ---
HFCs (hydrofluorocarbons)
PFCs (perfluorocarbons)
SF6 (sulphur hexafluoride)

Yes, gas is a noun. Greenhouse here is an adjective describing 'gas'. Together they make a noun phrase, 'Greenhouse gas'.
Nitrous Oxide is the third greenhouse gas.........
No, Ammonia is not considered a greenhouse gas.
The atmospheric lifetime is important because it helps to determine the long-term impact of the greenhouse gas. If there are efficient environmental removal mechanisms for a greenhouse gas (that is, if it has a short atmospheric lifetime) the gas will accumulate in the atmosphere more slowly than predicted by the rate at which it is emitted. If a greenhouse has a longer atmospheric lifetime, then even though not a lot of it is emitted from various sources, the atmospheric concentration of the gas will continually increase, allowing the gas to contribute to global warming for a long time.
Natural gas is a greenhouse gas, methane, and when it is burnt it releases the other greenhouse gas, carbon dioxide.
Yes, ozone is a greenhouse gas. Any gas with three or more atoms in their molecule are greenhouse gases.
Methane is another greenhouse gas twenty times more powerful than carbon dioxide. It is released from some agricultural practices, including cattle rearing and pig farming. It is also being released as frozen tundra and lakes melt.
The most abundant greenhouse gas is water vapor. Although not as potent as other greenhouse gases pound for pound, by sheer volume water vapor is the key greenhouse gas. Carbon dioxide is the second largest (by volume) greenhouse gas. Methane and nitrous oxide complete the four primary greenhouse gases, but there are only trace amounts of these in our atmosphere. Since water vapor is about 4% of the atmosphere, and CO2 concentrations are 400 parts per million, 0.04/0.0004 = 1%. In other words, CO2 is roughly 1% of the greenhouse gas.
CFCs (chlorofluorocarbons) destroy ozone.
Oxygen is not a greenhouse gas. It deceases the greenhouse gases.
