Complete rewrite from a physics major - okay, I dropped out, but I took some courses . . .
Line 1: Line 1: −
The process by which certain gases (principally water, carbon dioxide, and methane) trap infrared radiation that would otherwise escape the earth and dissipate in outer space.<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref>

The term ''"greenhouse effect"'' refers to the increased warmth of the earth's surface and atmosphere
 +
which results when gas molecules
 +
prevent the escape of [[infrared radiation]]
 +
from the earth.
 +
 
 +
This insulating effect has been compared to a blanket or to the glass walls and roof of a [[greenhouse]], but the process is not the same.
 +
 
 +
These "greenhouse gas" molecules (principally water, carbon dioxide, and methane)  
 +
absorb and re-emit longwave [[infrared rays]] emitted from the earth's surface into the atmosphere (see [[radiational cooling]]).
