The Pleistocene lasted from about 2,588,000 to 11,700 years ago.
 The name Plio-Pleistocene has, in the past, been used to mean the last ice age
According to Mark Lynas (through collected data), the Pleistocene's overall climate could be characterised as a continuous El Nio with trade winds in the south Pacific weakening or heading east, warm air rising near Peru, warm water spreading from the west Pacific and the Indian Ocean to the east Pacific, and other El Nio markers
