Relative Timing of Deglacial Climate Events in Antarctica and Greenland.
Science, Vol. 297, pp.1862-1864.
DOI: 10.1126/science.1074257
The last deglaciation was marked by large, hemispheric, millennial-scale
climate variations: the Bølling-Allerød and Younger Dryas periods in the
north, and the Antarctic Cold Reversal in the south. A chronology from
the high-accumulation Law Dome East Antarctic ice core constrains the
relative timing of these two events and provides strong evidence that
the cooling at the start of the Antarctic Cold Reversal did not follow
the abrupt warming during the northern Bølling transition around 14,500
years ago. This result suggests that southern changes are not a direct
response to abrupt changes in North Atlantic thermohaline circulation,
as is assumed in the conventional picture of a hemispheric temperature
seesaw.
STUDY NOTES: Oxygen isotope data of air and ice plus air methane concentration
for the last deglacial period, from the Law Dome ice core, Antarctica.
