New research finds Late Pleistocene glaciations terminated by Earth"s axis tilt rather than orbital eccentricity
Glacial cyclicity of the Earth has often been considered on 100,000 year timescales, particularly for the Late Pleistocene (~11,700 to 129,000 years ago) swapping between periods of extensive polar and mountain glacier ice sheets, to warmer interglac.....»»
