I'm an expert in the field of atmospheric science with a focus on energy balance and its implications for our planet's climate. The Earth's atmosphere is a complex system that involves various processes to maintain its energy balance. The energy that returns to the atmosphere comes from two primary sources: the Sun and the Earth itself.
The Sun is the primary external source of energy for Earth. Solar radiation, in the form of light, travels to Earth and is absorbed, reflected, and scattered by the atmosphere, clouds, and the surface. The amount of solar energy that reaches the Earth's surface is crucial for maintaining the planet's temperature and driving weather patterns.
Reflection: A portion of the incoming solar radiation is reflected back into space by the Earth's surface and the atmosphere. This reflection is what helps regulate the amount of energy that is absorbed by the Earth. The reflectivity of the Earth, known as the albedo, varies depending on the surface type and the presence of clouds. For example, ice and snow have a high albedo, meaning they reflect more sunlight and absorb less heat, contributing to a cooler surface temperature.
Radiation: The Earth also returns energy to the atmosphere through the process of radiation. As the Earth absorbs solar energy, it warms up and emits thermal infrared radiation, which is a form of heat energy. This radiation is emitted from the Earth's surface and the atmosphere and is radiated back into space. The balance between the incoming solar radiation and the outgoing thermal radiation is what maintains the Earth's average surface temperature.
Greenhouse Effect: The greenhouse effect is a natural process that plays a significant role in returning energy to the atmosphere. Certain gases in the Earth's atmosphere, known as greenhouse gases (GHGs), trap heat by absorbing and re-emitting thermal radiation. This trapped heat warms the atmosphere and the surface, preventing the Earth from becoming too cold. The primary greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
Human activities, such as burning fossil fuels and deforestation, have increased the concentration of greenhouse gases in the atmosphere. This has enhanced the greenhouse effect, leading to global warming and climate change. The balance of energy fluxes is being disrupted, causing temperatures to rise and altering weather patterns.
In summary, the Earth returns energy to the atmosphere through reflection of incoming solar radiation and by radiating heat in the form of thermal infrared energy. The greenhouse effect, a natural process involving greenhouse gases, plays a crucial role in maintaining the Earth's temperature by trapping heat. However, human-induced changes to the composition of the atmosphere are affecting this balance, with significant implications for our planet's climate.

Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). ... Earth's average surface temperature is maintained by two large, opposing energy fluxes between the atmosphere and the ground (right)--the greenhouse effect.
