Global warming is a moderate increase ,over time,in the average temperature of the earth's oceans,surface and atmosphere generally attributed to the greenhouse effect. The green house affect is the reaction of radiated solar energy ,as it passes thru the earths atmosphere to heat the earths surface and then it is expelled upward as heat. The gases in the atmosphere help to maintain the average temperature at 15oC ,but too many particles in the atmosphere has a continuous warming effect.
According to the National Oceanic and Atmospheric Administration (NOAA),the diagram below identifies the 7 key elements that would be expected to increase in a warming world and the 3 key elements would be expected to decrease:

The key ingredient's to global warming are:
H2O (g) water vapour
CO2 Carbon dioxide
CH4 Methane
N2O Nitrous Oxide
O3 Ozone
Thse Greenhouse gases also help regulate the temperature on earth.(BC Air Quality 2015)

It is the first 10 kms from the earth's surface into the atmosphere that has the most effect on the climate of the world and this is where all the global warming matter gets caught.(NMSEA 2014) Water vapour is the most significant greenhouse gas in the earths atmosphere, but this is largely due to natural climatic processes and not directly due to the actions of mankind. However when the levels of carbon dioxide increase evenly minutley, it can cause a dramatic increase in the earth's temperature.
This is because the molecular structure of water -H2O and carbon dioxide CO2 have internal vibrational modes which allow for the absorption and emitting of energy in the form of radiation. Water however easily condenses and evaporates as it adjusts quickly to the atmospheric conditions such as the re radiation from the earth and the energy from the sun.
Alternatively, carbon dioxide remains in the earths atmosphere for hundreds of years and acts as a controlling factor in determining the level at which heat energy is maintained within the atmosphere, thus temperatures are much higher.
