The Greenhouse Effect

These gases slow down the escape of heat. This makes the atmosphere warmer than it would be without it. In fact, if we did not have this natural greenhouse effect, the earth would have an average temperature of -5° F, instead of its current average temperature of 59° F. Eventually, the heat does escape into space.
