Outgoing heat is trapped by atmospheric greenhouse gases. 

The primary cause of rising atmospheric CO2 concentration is the burning of fossil fuels. Fossil fuels— natural gas, petroleum, and coal— provide approximately 90% of our society s energy. Combustion of fossil fuels, however, produces CO2. As an example, consider the combustion of octane (CgHjg), a component of gasoline.
