Abstract

Astronomical climate change The Croll–Milankovitch theory of climate change proposes that glacial–interglacial cycles are driven by changes in the amount of solar radiation reaching the Earth's surface at high northern latitudes in summer, in turn caused by changes in orbital geometry. To test this hypothesis Kawamura et al. constructed a new chronology for Antarctic ice cores using a proxy — the ratio of oxygen to nitrogen molecules in air trapped in the ice — that reflects changes in local summer insolation. The results show that orbital-scale Antarctic climate change has lagged Northern Hemisphere insolation during the past 360,000 years, and that increases in Antarctic temperature at the last four glacial–interglacial transitions took place within phases of increasing Northern Hemisphere summer insolation. The findings therefore support the Croll–Milankovitch hypothesis.
