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.ome of that heat is trapped by greenhouse gases in the atmosphere, including carbon dioxide (CO2).

Global warming is driven partially by human pollution. The pollutants that contribute to global warming are commonly known as greenhouse gas emissions. Carbon dioxide is probably the best known greenhouse gas, but methane, nitrous oxide and fluorinated gases also play a role in driving climate change (see Reference 1).Human activities that cause global warming pollution can be best understand by examining the various sources of each type of greenhouse gas.arbon dioxide represents 85 percent of all greenhouse gas emissions emitted from human sources in the United States (See Reference 2).
