View from Helicopter Flying over Greenland Tundra (VIDEO)
Caption
416,000 years ago, much of the Greenland ice sheet was melted and green with plants, new research in the journal Science shows. It may have looked something like this modern Greenland tundra landscape near the southeastern coast—or it may even have been a boreal forest. Pictured here is University of Vermont professor Paul Bierman (front seat, left) on an NSF-sponsored expedition several years before the research presented in the new Science study which he co-led.
