The Greenhouse Effect

The greenhouse effect naturally keeps the earth warm enough to be habitable; without it, the earth’s surface would be about 60 degrees Fahrenheit colder on average. 

Scientists refer to what has been happening in the earth’s atmosphere over the past century as the “enhanced greenhouse effect.” By pumping man-made greenhouse gases into the atmosphere, humans are altering and enhancing the process by which the atmosphere traps the sun’s heat before it can be released back into space.
