Earth Science

Earth’s rising seas are some of the most visible signs of our warming planet. Over the last 23 years, NASA satellite missions have observed a steady rise in global sea levels as polar ice sheets me...

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

Sea Level

In many communities in the U.S., sea level rise is already a factor in people’s lives in the form of high-tide flooding.

Altimeter Mission Series

Launching aboard the joint U.S.-European Sentinel-6 Michael Freilich satellite is NASA’s next instrument that will help improve weather forecasting.

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.
