Last year was a record-breaking one for Operation IceBridge, NASA’s aerial survey of the state of polar ice. For the first time in its nine-year history, the mission, which aims to close the gap between two NASA satellite campaigns that study changes in the height of polar ice, carried out seven...

With temperatures around the world climbing, melt waters from the continental ice sheets of Greenland and Antarctica are raising sea levels. Those ice sheets are melting from both above and below. Much of the ice lost from ice sheets comes from a process called calving where ice erodes, breaks off... Read More
