The Energy to Drive the Atmosphere
Weather patterns and ocean currents redistribute energy from latitudes with a surplus into latitudes with a deficit.

Earth’s Energy BalanceEarth’s overall average equilibrium temperature changes only slightly from year to year.
A balance exists between incoming solar energy (shortwave radiation) and outgoing energy from Earth to space (longwave radiation).

Without greenhouse gases, the average surface temperature of the Earth would be –18° C
No greenhouse gases(only permanent gases)
The current atmosphere(with greenhouse gases)
33° C differenceSource: Ahrens, C. D., 2008: Essentials of Meteorology,
