A new 27 ky high resolution East Antarctic climate record

The ice core recently drilled at the Dome Concordia site on the East Antarc tic plateau provides a new high resolution isotope record covering part of the last glacial, the last transition and the Holocene. The two step shape of the deglaciation is remarkably similar for all the ice cores now availab le on the East Antarctic plateau. The first warming trend ends about 14000 years ago and is followed by the well marked Antarctic Cold Reversal (ACR) with a secondary peak common to all records. During the deglaciation, there are more similarities between the near coastal site of Taylor Dome and inl and East Antarctica than between Taylor Dome and central Greenland. However , the results for EPICA do appear to confirm the Taylor Dome timescale afte r about 14 ka, showing cooling into the ACR roughly in phase between Greenl and and Antarctica. While the overall deglacial pattern is asynchronous, th is suggests that the now classical picture of a temperature seesaw between Antarctica and Greenland may be too simplistic.
