The greenhouse effect, despite all the controversy that surrounds the term, is actually one of the most well-established theories in atmospheric science. For example, with its dense CO2 atmosphere, Venus has temperatures near 700 K at its surface. Mars, with its very thin CO2 atmosphere, has temperatures of only 220 K.

The greenhouse effect is a natural occurrence that maintains Earth's average temperature at approximately 60 degrees Fahrenheit. Under normal conditions some of the sun's heat is radiated back into space. The 'Greenhouse Effect' occurs when heat is trapped in the atmosphere by gases. The greenhouse effect is

Greenhouse gases trap the heat brought by light passing through the atmosphere of the Earth. The major heat-trapping gases include water vapor, carbon dioxide, and methane. Earth would be a chilly place without the greenhouse effect - the average temperature would be 57ºF colder! Too much greenhouse effect also has consequences: Venus has an

Greenhouse effect simulation. The PhET Greenhouse Effect Simulation allows you to change the atmospheric greenhouse gas concentration, observe how these changes affect the movement of infrared photons into space, and determine how this ultimately affects temperature. If your instructor has not already done so, you will need download the PhET

the Earth’s natural greenhouse effect and account for about 90% of the total heat-retaining capacity of the atmosphere. Greenhouse gases can also reabsorb solar radiation reflected or reemitted from Earth’s surface, trapping the heat in our atmosphere instead of letting it escape to space. The Greenhouse Effect is a natural process essential

When greenhouse gases absorb infrared radiation, they radiate heat in all directions. Some of the heat goes into space, some is absorbed and radiated by the gases again, and some is radiated down, which keeps our planet warm. Without the greenhouse effect, all this heat would return to space, and Earth would be much too cold for us to live on.

Gases in the atmosphere can contribute to the greenhouse effect both directly and indirectly. Direct effects occur when the gas itself is a greenhouse gas. Indirect radiative forcing occurs when chemical transformations of the original gas produce a gas or gases that are greenhouse gases, when a gas influences the

greenhouse gases increases, then more infrared radiation will be absorbed and emitted back toward Earth’s surface, creating an amplified greenhouse effect. When averaged over the course of a year, the amount of incoming solar radiation received from the sun has balanced the amount of outgoing energy emitted from Earth.

the corresponding greenhouse effect is 24.520 C. The adiabatic model allows one to estimate the effect of so-called ‘‘greenhouse gases’’ on the temperature regimes of the Earth troposphere and its greenhouse effect. For asymptotic estimates, the writers assumed that the nitro-gen–oxygen Earth’s atmosphere is completely replaced by

( 21%), exert almost no greenhouse effect. Instead, the greenhouse effect comes from molecules that are more complex and much less common. Water vapor is the most important greenhouse gas, and carbon dioxide (CO 2) is the second-most important one.

The greenhouse effect will in fact operate even if the absorption of radiation were totally saturated in the lower atmosphere. The planet's temperature is regulated by the thin upper layers where radiation does escape easily into space. Adding more greenhouse gas there will change the balance. Moreover, even a 1% change in that delicate
