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

Abstract:
Because ice shelves respond to climatic forcing over a range of time
scales, from years to millennia, an understanding of their long-term
history is critically needed for predicting their future evolution. We
present the first detailed reconstruction of the Larsen C Ice Shelf (LCIS),
eastern Antarctic Peninsula (AP), based on data from sediment cores
recovered from below and in front of the ice shelf. Sedimentologic and
chronologic information reveals that the grounding line (GL) of an expanded
AP ice sheet had started its retreat from the midshelf prior to 17.7 ± 0.53
