Global Energy Balance

For temperature to remain stable, Earth’s energy budget must be in balance.

  • When Earth emits the same amount of energy as it absorbs, its energy budget is in balance, and its average temperature remains stable.

  • A significant increase or decrease in the Sun’s energy output would cause Earth to warm or cool. Satellite measurements taken over the past 30 years show that the Sun’s energy output has changed only slightly and in both directions. These changes in the Sun’s energy are thought to be too small to be the cause of the recent warming observed on Earth.
 

Biogeochemical cycles are reliant upon energy.

  • Ecosystems use energy to maintain biogeochemical cycles—such as the sedimentary, gaseous, and hydrologic cycles—between living and nonliving systems. (KEEP Conceptual Framework)
