Summary

Story summary

The Prudhoe ice dome in Greenland melted around 7000 years ago during a warm period.
This history suggests similar temperatures could recur by 2100, raising concerns for Greenland's ice sheet.
The GreenDrill project drilled 500 meters into the dome to collect sediment samples.
Models show up to 1 meter sea level rise this century.
There is disagreement on which region will melt first, but warming appears earlier in the north.
