  2. 1 day ago · Climate — a statistical description of the climate system — varies on all time scales. The IPCC defines climate variability: Deviations of climate variables from a given mean state (including the occurrence of extremes, etc.) at all spatial and temporal scales beyond that of individual weather events.
