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. They are the beers that guided you through college, the beers that make tailgates possible.
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.
A greenhouse gas (often abbreviated as GHG) is a gas that both absorbs and emits radiation in the infrared range, commonly called thermal radiation or heat. When present in the atmosphere, these gases trap radiation in the form of heat, causing a warming process called the greenhouse effect.he presence of four major greenhouse gases, namely water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) in the Earth's atmosphere keeps the average temperature of 15Âº C (59Âº F), whereas without the greenhouse effect the average temperature would be a frosty -18Âº C (0Âº F).
