"Project code: EC23015." Includes bibliographical references. "Greenhouse gases (GHGs) absorb energy from the sun and trap heat in the Earth's atmosphere. Without GHGs, Earth’s average temperature would be around -18°C, rather than the current average of 15°C. The Earth's natural greenhouse gas effect is one key parameter that makes the planet livable for humans. Human activities, such as the burning of fossil fuels, agriculture practices and industrialization, are changing Earth's natural greenhouse effect. As concentrations of greenhouse gases increase in the atmosphere, more heat is trapped and atmospheric temperatures rise. These indicators present atmospheric concentrations as measured from sites in Canada and at a global scale for 2 greenhouse gases: carbon dioxide and methane"--Page 5.
