Northern hemisphere forcing of climate cycles in Antarctica over the past 360,000 years
Article Abstract:
A new chronology for Antarctic ice is constructed and studied to test the hypothesis that glacial-interglacial cycles are driven by changes in amount of solar radiation reaching the Earth's surface at high northern latitudes in summer. Results show that the orbital-scale Antarctic climate has lagged Northern Hemisphere insolation during the past 360,000 years.

Regional insolation forcing of late quaternary climate change in the Southern Hemisphere
Article Abstract:
An independently dated terrestrial pollen record from a peat bog on South Island, New Zealand is presented to investigate global and local factors in Southern Hemisphere climate changes during the last two glacial-interglacial cycles. The results suggest that Southern Hemisphere isolation might have been responsible for these differences in timing.

Insolation-driven changes in atmospheric circulation over the past 116,000 years in subtropical Brazil
Article Abstract:
A high-resolution oxygen isotope record of an U/Th-dated stalagmite from subtropical southern Brazil, covering the past 116,200 years is presented. The oxygen isotope signature varies with shifts in the source region and amount of rainfall in the area, and hence records changes in atmospheric circulation and convective intensity over South America.
