Ice Age SUVs

Keep drilling; they're there:

The European Project for Ice Coring in Antarctica (EPICA) has managed to look back to the future. Their analysis of the ice core drilled at the Kohnen Station has revealed a significant link between temperature variations in Greenland and Antarctica -- a mechanism that governs the oscillation between warm and cold phases in the Northern and Southern hemispheres. "We call it the bipolar seesaw", says Hubertus Fischer, a researcher at Germanys Alfred Wegener Institute for Polar and Marine Research (AWI) and the main author of the new study.

His main concern was with the evidence of unusual climate change Greenland ice cores had revealed a few years ago. Temperatures during the last Ice Age, the cores revealed, had swung repeatedly up and down -- "by more than 10 degrees within a few decades," Fischer explains.
