Technical report

The earth works like a greenhouse. Carbon dioxide (CO2), methane, and other naturally occurring greenhouse gases (GHGs), as well as human-made industrial gases trap heat from escaping into space. This keeps the earth’s temperature within a life-sustaining range. Without the greenhouse effect, Earth would be much colder—an average temperature of –19° Celsius (C). Human reliance on fossil fuels for energy has increased the amount of CO2 in the atmosphere. Biogenic emissions of GHG from land use have magnified the greenhouse effect. Deforestation and poor land use, which have reduced the absorptive capacity of plants, forests, and soils for CO2, have made things worse.
