WebThe most important greenhouse gas is water vapor; carbon dioxide gas is a secondary greenhouse gas. These gases absorb some of the heat that the Earth radiates, and these gases then reradiate this heat themselves. Although these gases reradiate some of this heat into outer space, these gases also reradiate some of this heat back to the Earth.
