Description
Climate change refers to a change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties and that persists for an extended period, typically decades or longer. Climate change may be caused by natural internal processes or external forcings, or by persistent anthropogenic changes in the composition of the atmosphere or in land use.
