What are the gases excluding carbon dioxide in greenhouse gases?

Go measure it 21.9% ox 79% N 1.1 % greenhouse gases. Water vapor is not a greenhouse gas. the rest is so small it doesn't amount to nothing. CO2 is there major gripe that it has increased 30% in the last 30 yr. Wrong go measure it the green plants are doing a good job.LEAVE THE WATER VAPOR ALONE

The two gases contributing most significantly to the natural greenhouse warming of the earth are water vapor and carbon dioxide. Methane, nitrous oxide, ozone and sulfur hexafluoride are also greenhouse gases but make a smaller contribution to the greenhouse effect because their concentrations are so low. Other greenhouse chemicals, such as chlorofluorocarbons, perfluorocarbons, and hydrofluorocarbons, are synthetic and have only appeared in the atmosphere since the Industrial Revolution

Naturally occurring greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases.

taken from http://en.wikipedia.org/wiki/Greenhouse_gas The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. Note that it is not really possible to assert that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. (The higher ends of the ranges quoted are for the gas alone; the lower ends, for the gas counting overlaps.)[3] [4] Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons (see IPCC list of greenhouse gases). The major atmospheric constituents (N2 and O2) are not greenhouse gases, because homonuclear diatomic molecules (e.g. N2, O2, H2) do not emit in the infrared as there is no net change in the dipole moment of these molecules.
