Greenhouse gases are components of the atmosphere that contribute to the greenhouse effect. Without the greenhouse effect the Earth would be uninhabitable;[1] in its absence, the mean temperature of the earth would be about -19 °C (-2 °F, 254 K) rather than the present mean temperature of about 15 °C (59 °F, 288 K)[2]. Greenhouse gases include in the order of relative abundance water vapor, carbon dioxide, methane, nitrous oxide, and ozone. The majority of greenhouse gases come mostly from natural sources but are also contributed to by human activity
If you find out more about it, Greenhouse gasses are responsible for global warming.

Flatulence from cattle produces more so-called "greenhouse gases" than all the vehicles in the world. Therefore, eating more cows will help. Maybe a good slogan would help: "Eating a cow a day keeps global warming away".

It is basically CO2,SO2,NO2,CFC
On Earth, the major greenhouse gases are water vapor, which causes about 36–70% of the greenhouse effect (not including clouds); carbon dioxide (CO2), which causes 9–26%; methane (CH4), which causes 4–9%; and ozone, which causes 3–7%.[18][19] Some other naturally occurring gases contribute very small fractions of the greenhouse effect; one of these, nitrous oxide (N2O), is increasing in concentration owing to human activity such as agriculture. The atmospheric concentrations of CO2 and methane have increased by 31% and 149% respectively above pre-industrial levels since 1750. These levels are considerably higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores. From less direct geological evidence it is believed that CO2 values this high were last attained 20 million years ago.[20] Fossil fuel burning has produced about three-quarters of the increase in CO2 from human activity over the past 20 years. Most of the rest is due to land-use change, in particular deforestation.[21]
The present atmospheric concentration of CO2 is about 383 parts per million (ppm) by volume.[22] Future CO2 levels are expected to rise due to ongoing burning of fossil fuels and land-use change. The rate of rise will depend on uncertain economic, sociological, technological, and natural developments, but may be ultimately limited by the availability of fossil fuels. The IPCC Special Report on Emissions Scenarios gives a wide range of future CO2 scenarios, ranging from 541 to 970 ppm by the year 2100.[23] Fossil fuel reserves are sufficient to reach this level and continue emissions past 2100, if coal, tar sands or methane clathrates are extensively used.[24]
Positive (reinforcing) feedback effects such as the expected release of up to 70,000 million tonnes of methane from the melting of permafrost peat bogs in Siberia may lead to significant additional sources of greenhouse gas emissions[25] not included in climate models cited by the IPCC.[1]

the increase in the use of fuels like coal and petroleum has accelerated the emission of carbon dioxideinto the atmosphere. deforestation and forest fire contribute to the increase in the deposit of carbon dioxide

here's the list...

radiative forcing means reflecting radiation back into our atmosphere...and thus increasing temperature...
