www.weather.govozone, and several other gases also contribute to the greenhouse effect. Adding more greenhouse gases, such as CO 2, to the atmosphere intensifies the greenhouse effect. The Greenhouse Effect is necessary for life on Earth, as we know it, to survive. The effect is enhanced by human activities, such as the burning of fossil fuels.
Blackbody radiation and greenhouse effect
www.clarkson.eduresults in a greenhouse effect, which refers to the absorption of longwave radiation by gases in the atmosphere. The greenhouse effect results in Earth’s temperature being warm enough to sustain life. The concentrations of greenhouse gases in the atmosphere determine the average global temperature.

ccir.ciesin.columbia.eduthe greenhouse effect. Methane (CH 4), nitrous oxide (N 2 O), chloro-fluorocarbons (CFCs) and other greenhouse gases are present only in trace amounts, but can still have a powerful warming effect due to their heat-trapping abilities and their long residence time in the atmosphere. Without the greenhouse effect, Earth’s aver-
