In order for the sun-earth system to be in equilibrium, the earth must emit the same amount of energy it absorbs (though not necessarily at the same wavelength).

Absorption / reflection of sunlight - Understanding Global Change

WebThe Earth’s climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ... WebRe-radiation of heat. The sun is continuously sending out solar radiation in all directions. Sunlight that reaches Earth’s surface and atmosphere is either absorbed or reflected. Absorbed energy gets re-radiated the in the form of infrared, also known as longwave radiation. Infrared radiation is invisible to our eyes, but we feel it as heat. northland adventures nominee trust
