Antarctic ice cores provide a long 800ka- record of a variety of climatic, atmospheric and environmental properties. It shows in particular the full succession of the different interglacial periods named as odd-numbered Marine Isotopic Stages (MIS 1 to 19 for the last 800 ka). The ice record is unique in the sense that it shows the greenhouse gas changes (CO2, CH4, N2O) occurring at the worldwide scale. It also provides a variety of climatic and environmental properties at semi-hemispheric or more regional scale, which allows the comparison with the information obtained from the marine and continental records.
The presentation will focus on interglacial periods (MIS 11, MIS19) of the last 800 ka considered as possible analogues of the Holocene, the present interglacial, in the absence of any anthropogenic influence, and on the comparison between pre and post “MBE” interglacials.
Finally, I will say a few words about one of the major project proposed by the International Partnerships in Ice Core Sciences (IPICS) and dealing with the search of ice cores older than one million of years and the implication regarding the mystery of the MPT.
