A recent study indicates the Prudhoe Dome ice cap in Greenland completely melted about 7,000 years ago. This raises concerns about future sea level rise due to ongoing climate change. The University at Buffalo conducted the research as part of the GreenDrill project. Published in Nature Geoscience, the study emphasizes the region's sensitivity to small temperature increases. The melting occurred during the Holocene epoch, a period known for climate stability. Researchers used luminescence dating to determine when sediment under the ice was last exposed to sunlight. Results showed exposure between 6,000 and 8,200 years ago, suggesting temperatures 3 to 5 degrees Celsius warmer than today. The Prudhoe Dome melt is a reminder of the impact of human-caused climate change on Greenland's ice and global sea levels.
