The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases causing radiative forcing and contributes to global warming.
Some of that heat is trapped by greenhouse gases in the atmosphere, including carbon dioxide (CO2). Human activity--such as burning fossil fuels--causes more greenhouse gases to build up in the atmosphere.As the atmosphere thickens with more greenhouse gases, more heat is held in. Fossil fuels such as oil, coal and natural gas are high in carbon and, when burned, produce major amounts of carbon dioxide or CO2.A single gallon of gasoline, when burned, puts 19 pounds of carbon dioxide into the atmosphere.ome of that heat is trapped by greenhouse gases in the atmosphere, including carbon dioxide (CO2).
