See the heating of the planet's surface arising from the blanketing effect of anthropogenic carbon dioxide in the air.

What gases? carbon-dioxide, Nitrous oxide, Methane and Chloro flurocarbons. We know most about carbon dioxide because it gets the most publicity. Take note that Ozone and sulphur dioxide act as serious pollutants and may contribute to global warming as well.


What does the atmospheric green house effect do? Heat tries to escape by the process of outgoing blackbody infrared radiation. Some of the energy passes through the air and some is absorbed and transmitted both upward and downward. This happens all the time.

When we talk about the greenhouse effect increasing, that means the atmosphere becomes better at absorbing and stopping the outgoing heat in the first place and making the atmosphere stay at a warmer temperature than it did before.

The same amount of heat leaves the earth as what enters even at the "new level" (state of higher global temperatures). Scientists call that an equilibrium. A change in the absorption characteristics in the atmosphere above just means that a higher global temperatures is needed to produce the mix of emitted radiation wavelengths that will maintain heat-flow equilibrium.
