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).

It is a global threat with real implications for everyone no matter where you live. Global warming is caused by a variety of gases and materials in our atmosphere; including huge amounts of carbon dioxide and methane from human activities such as extracting and burning fossil fuels, and clearing forests. These gases can trap heat in the atmosphere, causing steadily increasing temperatures.
