Greenhouse effect

Earth is getting warmer. The amount of CO2 getting higher and this amount seems to increase continually.
The atmosphere helps the Earth to be warm. When water vaporizes, carbon dioxide and methane( Methane is 21 times more dangerous than carbon dioxide) are blocking the heat that comes from the sun and these two are keeping the surface of the Earth warmer. If the amount of these gases increases, the earth will transform into a giant greenhouse and the impact will be extraordinary. 
The burning of the fossil raw will increase the greenhouse effect in the atmosphere.
