The entire event lasted about 150 years (Thomas et al., 2007; Kobashi et al., 2007) and then temperatures warmed, returning to their previous levels.

Milder than the Younger Dryas cold spell that preceded it, but more severe than the Little Ice Age that would follow, the 8.2 kiloyear cooling was a significant exception to general trends of the Holocene climatic optimum.
