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.
Global warming is driven partially by human pollution. The pollutants that contribute to global warming are commonly known as greenhouse gas emissions. Carbon dioxide is probably the best known greenhouse gas, but methane, nitrous oxide and fluorinated gases also play a role in driving climate change (see Reference 1).Human activities that cause global warming pollution can be best understand by examining the various sources of each type of greenhouse gas.arbon dioxide represents 85 percent of all greenhouse gas emissions emitted from human sources in the United States (See Reference 2).
