Study finds forgotten Cold War nuclear base in Greenland was once ice-free, with summers 4.7°C warmer about 416,000 years ago
- Image: Pictorial ParadeA forgotten Cold War military base buried beneath Greenland's ice is giving scientists an unusual glimpse into a much warmer Earth.
- Researchers examined sediment recovered from Camp Century in northwestern Greenland, a site built by the US Army Corps of Engineers in 1959 and abandoned in 1967.
- The sediment contained biological markers that allowed scientists to reconstruct summer temperatures and moisture conditions about 416,000 years ago, during Marine Isotope Stage 11.
