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...

Jason-3 Launch

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.

For NASA scientist Severine Fournier, studying our planet knows no borders.

Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature.

El Niño/La Niña - (12/1996 - 01/2000)

Here we provide side by side comparisons of Pacific Ocean sea surface height (SSH) anomalies of what is presently happening in 2015 with the Pacific Ocean signal during the famous 1997 El Niño.
