What effect does an increase in greenhouse gas concentration have on earth budget of the earth?

Man-made forcings include particle pollution (aerosols) that absorb and reflect incoming sunlight; deforestation, which changes how the surface reflects and absorbs sunlight; and the rising concentration of atmospheric carbon dioxide and other greenhouse gases, which decreases the rate at which heat is radiated heat transfer.

Explanation:

Effect on Surface Temperature

The natural greenhouse effect raises the Earth's surface temperature to about 15 degrees Celsius on average-more than 30 degrees warmer than it would be if it didn't have an atmosphere.
