As fancy microbrews slowly make the transition to 16oz pounder cans, let us take pause and celebrate the macro forefathers that pioneered the God-given right to slug back a watery beer, then slam their containers over your head.

greenhouse gas - a gas that contributes to the greenhouse effect by absorbing infrared radiation. greenhouse emission. CFC, chlorofluorocarbon - a fluorocarbon with chlorine; formerly used as a refrigerant and as a propellant in aerosol cans; the chlorine in CFCs causes depletion of atmospheric ozone.
The atmosphere is made up of many different gases. Several gases have the ability to reflect the sun's energy radiating from the earth back to the earth as heat. The gases with this capability are known as greenhouse gases (GHGs). The main GHGs are water vapor, carbon dioxide, methane, and nitrous oxide. Without some level of GHGs in the atmosphere, the earth would be much colder than it is and life on this planet would be much different.
