New observations and more powerful computer models allow scientists to peer beneath the ice of Greenland and Antarctica.

NASA's Sea Level Change Team will meet in Annapolis, Maryland, on March 11-13 to share research results, further collaborative efforts and discuss the team's next direction.

A NASA-led study has found that a giant, growing cavern two-thirds the area of Manhattan is contributing to the rapid melting of Antarctica’s Thwaites Glacier.

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.
