Overview of Greenhouse Gases. : 1  Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products, and also as a result of certain chemical reactions (e.g., manufacture of cement).
As you can see from the graphs, the amount of carbon dioxide in the atmosphere has increased steadily over the past 150 years, and so has the average global temperature. Some of this is due to human activity. Along with other gases such as methane and water vapour, carbon dioxide is a greenhouse gas. It absorbs heat energy and prevents it escaping from the Earthâs surface into space. The greater the amount of carbon dioxide in the atmosphere, the more heat energy is absorbed and the hotter the Earth becomes.
