• 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. • The results help overturn a previous view that much of the Greenland ice sheet persisted for most of the last two and a half million years. Instead, moderate warming, from 424,000 to 374,000 years ago, led to dramatic melting. • At that time, the melting of Greenland caused at least five feet of sea level rise, despite atmospheric levels of heat-trapping carbon dioxide being far lower than today (280 vs.
