Two new satellite images remind us that Earth’s ice sheets are losing so much mass it’s becoming obvious from space.

In the vivid new maps published as part of an April 30 study in the journal Science, researchers illustrated 16 years of ice loss in Greenland and Antarctica as seen by a laser-emitting NASA satellite. The images paint a picture of rapid melt around the coasts of both regions (shown in red and purple in the maps), far outweighing modest ice-mass gains (shown in light blue) farther inland.
