Abstract

The term climate refer to the average weather over a long period of time, which, based on the recommendations of the World Meteorological Organization, is 30 years. Weather is described by a set of local parameters such as the earth surface temperature, humidity, precipitation level, wind speed, and so on; nevertheless, the temperature is the most significant one. Global climate is also mainly defined by the average earth temperature, for which the currently adopted value is 15°C. The temperature of the earth is a consequence of the thermal radiation energy balance among the earth, the sun, and the extraterrestrial space.
