By trapping heat from the warm earth that would otherwise escape into space.

Answer:

Greenhouse gases warm the air near earth’s surface by trapping the heat in the atmosphere.

Explanation:

The greenhouse gases are those that made a layer that maintains the heat in the atmosphere. Greenhouses have their roof made of glass to trap the heat from the sun because the heat that enters is higher than the heat that escapes.  

The greenhouse gases are carbon dioxide, methane, nitrous oxide, and fluorinated gases.
