Scientists report much of the Artic island's ice melted as recently as 416,000 years ago, which has implications for sea-level rise. Newly analyzed samples from underneath Greenland's vast ice sheet reveal the Arctic island was considerably greener as recently as 416,000 years ago. This discovery
Long-lost ice core reveals that most of Greenland was green 416,000 years ago. A large portion of Greenland was an ice-free tundra landscape perhaps covered by trees and roaming woolly mammoths in the recent geologic past (about 416,000 years ago), a new study in the journal Science shows. T
