ABSTRACT: The Milankovitch theory of climate change proposes that glacial- interglacial cycles are driven by changes in summer insolation at high northern latitudes. The timing of climate change in the Southern Hemisphere at glacial-interglacial transitions (which are known as terminations) relative to variations in summer insolation in the Northern Hemisphere is an important test of this hypothesis. So far, it has only been possible to apply this test to the most recent termination, because the dating uncertainty associated with older terminations is too large to allow phase relationships to be determined. Here we present a new chronology of Antarctic climate change over the past 360,000 years that is based on the ratio of oxygen to nitrogen molecules in air trapped in the Dome Fuji and Vostok ice cores. This ratio is a proxy for local summer insolation, and thus allows the chronology to be constructed by orbital tuning without the need to assume a lag between a climate record and an orbital parameter. The accuracy of the chronology allows us to examine the phase relationships between climate records from the ice cores and changes in insolation. Our results indicate that orbital-scale Antarctic climate change lags Northern Hemisphere insolation by a few millennia, and that the increases in Antarctic temperature and atmospheric carbon dioxide concentration during the last four terminations occurred within the rising phase of Northern Hemisphere summer insolation. These results support the Milankovitch theory that Northern Hemisphere summer insolation triggered the last four deglaciations. ADDITIONAL REFERENCES: Raw data: Watanabe, O., J. Jouzel, S.

DESCRIPTION: Preliminary reconstruction of air temperature at Dome Fuji (Antarctica) for the past 340,000 years from isotopic data (d18O and dD) of the first Dome Fuji ice core. The Dome Fuji temperature (delta-Tsite, deviation from the mean of the last 10 kyr) was reconstructed by correcting raw isotopic records of the ice core for vapor source temperature and seawater isotopic composition variations, using an isotopic inversion (Vimeux et al., 2002; Stenni et al., 2004). Due to high noise level in the deuterium excess data especially between 20 and 80 ka, we use a filtered record (passband>5000yr, stopband<2000yr). Note that this data is not intended to resolve millennial changes because of the filtering of the raw data as well as averaging of delta-Tsite to 500-yr intervals. We used a recent seawater d18O reconstruction by Bintanja et al (2005, Nature). We estimate the sensitivities of isotopic values (Uemura et al., 2004) to site (Dome Fuji) and source temperatures and seawater isotopic composition, by using a Rayleigh-based model. We tune this model with the Dome Fuji present-day surface data. We currently lack isotopic data of surface snow from the coast to Dome Fuji to define the air mass trajectories, thus this data should be considered preliminary. Nevertheless, the tuned sensitivities are close to those for Vostok and Dome C (Vimeux et al., 2002; Stenni et al., 2004). The data are put on DFO-2006 age scale and averaged at 500 yr intervals. The value is the mean in the range from 'Top age' to the next 'Top age'. For plotting the data, use staircase (cityscape) function using 'Top age', or linear function using 'Center age'. Note that age is in b2k (before AD 2000).
