Climate

The climate is commonly measured to be the weather averaged over a long period of time, naturally 30 years. Somewhat more precisely, the concept of "climate" also includes the statistics of the weather - such as the degree of day-to-day or year-to-year difference expected. IPCC is called as Intergovernmental Panel on Climate Change.

Climate in a narrow sense is usually defined as the "average weather", or more meticulously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time range from months to thousands or millions of years. The traditional period is 30 years, as defined by the World Meteorological Organization (WMO). These quantities are the majority often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a numerical description, of the climate system.
