The greenhouse gases are the major cause of the global warming. These gases act like green house by allowing the heat from the sun to enter the earth surface with out letting it to radiate back to the space. The green house gases is the name that scientists for carbon dioxide, nitrous oxide and methane. These gases mostly produced by us as humans. We cut the trees that absorb the CO2, we burn fossil fuels, we use cars and we use electricity produced by burning coals all that produce greenhouse gases.
