From big to small, each of us is part of the gorgeous mosaic of Earth. Learn how you can connect to NASA's Earth Day 2021 activities.

A research team camped on Russell Glacier near Kangerlussuaq, Greenland, to study how water volume changes under the Greenland ice sheet influence how quickly a glacier adds to sea level rise.

Teams are headed out by land, water, and air to collect data that will be used to forecast land gain and loss in the Mississippi River Delta as a result of sea level rise.

Designed to spot potential natural hazards and help researchers measure how melting land ice will affect sea level rise, the NISAR spacecraft marks a big step as it takes shape.

Scientists with NASA’s Oceans Melting Greenland mission are probing deep below the island’s warming coastal waters to help us better predict the rising seas of the future.

As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise contribution.
