Here is what the page “Forgotten Greenland Cold War Samples Reveal Ice-Free Past and Warmer Summers” contains. Sediment cores collected in the 1960s from beneath a former U.S. military base in Greenland—and then forgotten for decades—have revealed that the site was ice-free during an ancient period when summers were a few degrees warmer than today. The study, led by the University at Buffalo, analyzed ancient soil and plant remains from beneath Camp Century, a Cold War base built by the U.S.
The findings, published in the journal Science, show that Greenland's ice sheet melted away at this location within the last million years, possibly as recently as 400,000 years ago, when atmospheric carbon dioxide levels were much lower than today. This suggests the ice sheet may be more sensitive to warming than previously thought. The research matters because Greenland's ice sheet holds enough water to raise global sea levels by about 7 meters, and understanding its past behavior helps scientists predict future melting.
