Portrait of Lord Melvyn Bragg, host of In Our Time

History of climate variability and change

Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. In addition to the general meaning in which climate change may refer to any time in Earth's history, the term is commonly used to describe the climate change that is now underway.
