• "The medium term climate changes includes the semi-regular advances and retreats of the glaciers during an individual Ice Age. The last 2.8 Ma have been marked by large global climate oscillations that have been recurring at approximately a 100,000 yr. periodicity at least for the past 800,000 years. The warm periods, called interglacial periods, appear to last approximately 15,000 to 20,000 years before regressing back to a cold ice age climate."
