slide 1 - Lake formed in melting glacier

Landsat illustrates five decades of change to Greenland glaciers

Glaciers shrink and more rock is exposed in satellite images. Full story ›

slide 2 - GRACE-FO shows the weight of Midwestern floods

GRACE-FO shows the weight of Midwestern floods

Data from the mission show water weight gain across the U.S. Midwest and rapid weight loss from Greenland's melting ice. Full story ›

slide 3 - Flowing Antarctic ice mapped 10 times more accurately

Flowing Antarctic ice mapped 10 times more accurately

The new map of ice flow speeds throughout Antarctica will improve our understanding of the vast continent and of future sea level rise. Full story ›

slide 4 - Image from Antarctic simulation

Melting ice, warming ocean: Take control of a new simulation

You can adjust temperature, snowfall and other factors to control ice melt in Antarctica. Full story ›

slide 5 - Greenland simulation image

These glaciers melt at your fingertips

A new simulation lets you take control of ice melt in Greenland over 12,000 years. Full story ›
