Drones show Greenland ice sheet fracturing in real time

Scientists said Monday they had used a drone to observe the rapid fracturing and draining of a lake on the Greenland ice sheet, a phenomenon that may become more frequent as a result of climate change.The ice sheet is typically about a kilometer thick, and during summer, it is normal for some of the surface to melt and form thousands of lakes.This process has been extremely difficult to observe firsthand, but a group of glaciologists from the Scott Polar Institute at the University of Cambridge
