The Subboreal is a climatic period, immediately before the present one, the subatlantic period. Both are part of the Holocene epoch. It lasted from 3710 to 450 BCE. During this time, conditions on earth were somewhat warmer and drier than the present with lower levels of carbon dioxide. There were important changes to vegetation, sea level, and the expansion of human civilizations, and the first instances of human recorded history.
