Ice losses from Antarctica have tripled since 2012, increasing global sea levels by 0.12 inch (3 millimeters) in that timeframe alone.

A patch of high sea level called a Kelvin wave is slowly traveling east along the equator in the Pacific Ocean. This type of wave is often a precursor to an El Niño event.

GRACE Follow-On has launched, and both satellites are communicating with ground stations.

Scientists have combined NASA Earth satellite observations with data on human activities to map locations where freshwater is changing around the globe and to determine why.

Revised dates have been set for the prelaunch briefing and launch of GRACE-FO, NASA's latest Earth-observing satellite mission.

Operation IceBridge, NASA’s longest-running airborne mission to monitor polar ice change, concluded this year’s springtime survey of Arctic sea and land ice.
