Description


This book provides a comprehensive presentation of Earth's energy flows and their consequences for the climate. The Earth's climate as well as planetary climates in general, are broadly controlled by three fundamental parameters: the solar irradiance, the planetary albedo and the planetary emissivity. Space measurements indicate that these three quantities are remarkably stable. A minor decrease in planetary emissivity is consistent with theoretical calculations. This is due to the ongoing increase of atmospheric greenhouse gases making the atmosphere more opaque to long wave terrestrial radiation. As a consequence radiation processes are slightly out of balance as less heat is leaving the Earth in the form of thermal radiation than the incoming amount of heat from the sun. Present space-based systems cannot yet satisfactorily measure this imbalance, but the effect can be inferred from the measurements of the increase of heat in the oceans. Minor amounts of heat are also used to melt ice and to warm the atmosphere and the surface of the Earth.

The book brings to fore the complexity of feedback processes of the Earth's climate system and in particular the way clouds and aerosols affect the energy balance both directly and indirectly through feed-back loops driven by the dynamics of atmospheric, ocean and land surface processes. The book highlights recent scientific progress as well as remaining challenges.
