Ice Reveals Polar Temperature Seesaw A new ice core from Antarctica directly correlates abrupt changes in Greenland's climate over the last 150,000 years with counterpart changes in Antarctica -- offering further indication that the two icy regions are connected by ocean currents in a sort of bipolar seesaw. |
