Why is it called "green houes gas's"?

Question

cuz arnt green houes good? they grow plants that clean the air. so why did they name it green houes gas's?

Answer 1

Green house gas comes from our flora.

Answer 2

the main greenhouse gasses.

methane, ozone, nitrogen oxides (N2O NO NO2), water, CFCs and HFCs.

greenhouse gasses lower the amount of heat escaping into space by re absorbing the infra red radiation emitted by the earth. this is called the greenhouse effect. the greenhouse effect keeps the earth a good 20 degrees warmer then it would be without greenhouse gasses.

more greenhouse gasses prevents more heat from escapeing from the earth and so the earth will warm. this is not good because warming the entire earth can cause prolbems such as desertification and droughts. although some places may be better off most will still be worse off due to global warming.

Answer 3

It holds hit in, like a greenhouse.

Answer 5

The major 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%. It is not possible to state 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 (nitrogen, N2 and oxygen, O2) are not greenhouse gases. This is because homonuclear diatomic molecules such as N2 and O2 neither absorb nor emit infrared radiation, as there is no net change in the dipole moment of these molecules when they vibrate. Molecular vibrations occur at energies that are of the same magnitude as the energy of the photons on infrared light. Heteronuclear diatomics such as CO or HCl absorb IR; however, these molecules are short-lived in the atmosphere owing to their reactivity and solubility. As a consequence they do not contribute significantly to the greenhouse effect.

Late 19th century scientists experimentally discovered that N2 and O2 did not absorb infrared radiation (called, at that time, "dark radiation") and that CO2 and many other gases did absorb such radiation. It was recognized in the early 20th century that the known major greenhouse gases in the atmosphere caused the earth's temperature to be higher than it would have been without the greenhouse gases
