Earth'sEnergy Balanceand the Greenhouse Effect. The global average surface temperature of the earth is determined by abalancebetween theenergyadded to the earth by the sun and theenergyradiated away by the earth to space. Greenhouse gases, both natural and anthropogenic (or, human-affected), affect thisenergy balance.
