The ultimate goal: obtain and analyze ice samples from the last time Earth was significantly warmer than present -- the Eemian era of roughly 120,000 to 130,000 years ago. Some climate models predict that by 2100, Earth's average temperatures could again match those of the Eemian period (5-9° Fahrenheit warmer, on average, than present).
