On the Greenland Ice Sheet, the ice flow more than doubles in speed in many regions during summer, as surface melt drains to the bed and lubricates the motion. This acceleration sends ice to the sea faster. However, the motion also slows down in late summer, fall, and winter, which largely offsets the summer speedup. New modeling data shows that a complex drainage system beneath the ice holds the giant sheet back more than previously understood. Courtesy/LANLLANL News:
