Summary
Abstract: A precise relative chronology for Greenland and West Antarctic paleotemperature
is extended to 90,000 years ago, based on correlation of atmospheric methane
records from the Greenland Ice Sheet Project 2 and Byrd ice cores. Over this
period, the onset of seven major millennial-scale warmings in Antarctica
preceded the onset of Greenland warmings by 1500 to 3000 years. In general,
Antarctic temperatures increased gradually while Greenland temperatures were
decreasing or constant, and the termination of Antarctic warming was apparently
coincident with the onset of rapid warming in Greenland. This pattern provides
further evidence for the operation of a "bipolar see-saw" in air temperatures
and an oceanic teleconnection between the hemispheres on millennial time
scales.
