Physics Perspective • Global warming is a matter of heat balance: Earth's temperature rises until the heat flowing out of the earth balances the heat flowing into it. Meaning If the earth cannot release the heat before the new one come in from particular sources (i.e. Sun), earth’s temperature will accumulate.
How the Earth Releasing Heat? Because the earth is an isolated object; therefore, there’s only one way the earth can exchange heat with the rest of universe, which is through thermal radiation. Balance heat from the sun Heat lost to outer space Heat returned to earth
The atmospheric temperature of the Earth is in an approximately stable state as incoming heat from the sun is, in turn, reflected out into space, maintaining an income-outflow energy balance. For more on the physics and chemistry of the atmosphere
