Tectonic processes and the "ghosts" of past ice sheets are contorting, lifting and pulling Greenland in different directions, new research reveals.
Greenland sits on the North American tectonic plate, which has dragged the island northwest by 0.9 inches (23 millimeters) per year over the past two decades. Researchers have been monitoring this drift for some time, but a new study analyzing satellite data has found that there is far more to the movement and to other deformations than just plate tectonics.
