Introduction: The temperature near the surface of the Earth is in thermodynamic equilibrium when the absorption of radiant energy from the sun is in approximate balance with the emission of radiant energy to space by the planet. Sources of heat that are internal to the Earth system are negligible in a global sense. The energy output of the sun is a critical control on the Earth?s climate. The amount of available solar energy absorbed by the Earth depends on its reflectivity, which is strongly dependent on the fractional coverage and optical properties of clouds in the atmosphere, aerosol amount and properties, atmospheric humidity, and the condition of the surface. These properties in turn interact with the temperature distribution and circulation of the atmosphere. Surface ice cover is sensitive to the global mean temperature of the Earth, and cloud amount and properties may also change with the mean climate...
