Sea Surface Height - Global Average from 1993 - 2011.

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand...

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.

For NASA JPL engineer Parag Vaze, studying Earth’s rising ocean has been a career three decades in the making.

This video discusses the water cycle, which is the movement of water around the Earth, and its importance to life. Changes to the water cycle affect climate and vice versa.

The Falcon 9 protective payload fairing containing the Sentinel-6 Michael Freilich satellite

NASA and its U.S. and international partners have teamed up to launch a new Earth-observing satellite called Sentinel-6B that will measure sea surface height of most of the planet’s ocean. These ob...

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

The Sentinel-6 Michael Freilich satellite sits in front of a testing chamber where mission team members tested whether the spacecraft could endure the loud sounds it will encounter during launch.

Karl and Seymour learn how carbon dioxide is formed in this sketch from The Lollygaggers, a global warming sketch comedy.

Oceans' Role in Climate - Jason-1

It's hard to "see" sea level rise by just looking at the ocean, but its effects are very real.
