Short climate shifts of the last glacial and Holocene periods, including the Younger Dryas, the 8.2 and 4.2 kiloyear events and the volcanic winter of 536. An event belongs here when its cited article describes a rapid cooling or drought within the last twelve thousand years. It excludes deep-time climate events. Ice cores, tree rings and sediments record these shifts, and they are used to understand how fast climate can change.
