Scientist Interviews

Scientists used computer modeling techniques to tease apart the effects of natural variability and climate change on rates of sea-level rise.

Snowfall accumulation in parts of Antarctica increased in the 20th century. The added precipitation has led to some mitigation of sea level rise. Overall, Antarctica still lost far more ice than it gained.

Less than three months into its mission, NASA’s Ice, Cloud and land Elevation Satellite-2, or ICESat-2, is already exceeding scientists’ expectations.

New NASA maps show that a group of glaciers spanning one-eighth of East Antarctica’s coast have begun to lose ice over the past decade, hinting at widespread changes in the ocean.

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.
