Antarctica's Pine Island Glacier calved, or broke off, an iceberg three times the size of Manhattan, adding to a lengthening list of major "calving events" that are contributing to global sea level rise.
NASA’s decade-long airborne survey of polar ice is once again probing Antarctica, this time while the agency’s newest satellite mission studies it from space.
In an effort to better understand the ocean's role in Greenland's rapid ice loss, researchers must drop scientific probes safely into open water around the island's coast.
NASA has identified three processes responsible for wobbles in Earth's axis of rotation: water mass loss primarily in Greenland, glacial rebound, and mantle convection.
A science team tallies up the many contributions to sea level rise, such as melting ice and warming, expanding oceans.
