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.

Greenland and Antarctica are home to most of the world's glacial ice – including its only two ice sheets – making them areas of particular interest to scientists.

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft. Liftoff was at 10:42 a.m. PST (1:42 p.m. EST).

Our World: How High is the Ocean?

On the left is Sea Surface Height Anomalies (SSHA) relative to the sea level mean (1993-2018). On the right is Global Mean Sea Level (GMSL) with the sea level trend as the straight line. The data a...

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...

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

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...

One of the best ways to understand Earth's ocean is from the perspective of space.

Watch the Jason-3 Mission Briefing from Friday, Jan 15, 2016 - panelists gave an overview of the Jason-3 mission.

The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. With ...

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 over 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our Ocean to war...

El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. The warmer water associated with El Niño displaces colder water in the upper layer of the ocean caus...

Sea Level Isn't Level - Why it matters

QuickTime VR of TOPEX/Poseidon

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

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

Fathoming the forces that determine global sea levels can be daunting. We present a guide to the basics of ocean surface topography.

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

Earth’s global sea levels are rising – and are doing so at an accelerating rate.
