Climate and atmospheric history of the past 420,000 years from the Vostok ice core, Antarctica

The main features of the more recent Vostok climate cycle have similarities with those seen in earlier cycles. It has been possible to identify a strong connection between atmospheric greenhouse-gas concentrations and Antarctic temperature, along with the strong imprint of obliquity and precession in most of the climate time series. This research supports the view that greenhouse gases have played a strong role in the glacial-interglacial change.
