Decline in atmospheric carbon dioxide key to ancient climate transition
Description: A team of international scientists used new geochemical measurements, coupled with a model of the 'Earth system', to show that the growth and changing nature of continental ice sheets, approximately a million years ago, coincided with a cascade of events that ultimately lowered atmospheric CO2 during glacial intervals - periods when the Earth. The researchers have shown this change was key in triggering what is known as the Mid-Pleistocene Transition (MPT), which lasted around 400,000 years. The MPT had long lasting effects on the frequency at which the Earth transitioned between periods of warm and cold climate, (the 'ice age cycles'). [Source: University of Southampton]
