NASA Climate Watcher Waves Goodbye

Decades of Discovery - How altimeters help us every day.

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...

Changing conditions in the Pacific have stirred up Earth’s largest ocean and redistributed its heat, piling up warm waters along U.S. Western shores and raising sea level in the process.

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.

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

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

To provide scientists with essential information about global and regional changes in the seas, NASA will launch the Jason-3 satellite from Vandenberg Air Force Base in California.

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. NASA Science Live was recorded Tuesday, Nov. 17, 2020, and featured...

NASA and its partners announced the renaming of the mission, previously known as Sentinel-6A/Jason-CS.

Our World: How High is the Ocean?

Sea Level Isn't Level - Why it matters

This animation illustrates the evolution of sea surface temperature (SST) anomalies (relative to the respective normal state) in the Pacific Ocean associated with the 2015-2016 El Niño.

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

Watching Our Oceans

Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satelli...

A key ocean observation satellite has been named after Earth scientist Michael Freilich

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.

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...

The ocean-observing Sentinel-6 Michael Freilich satellite launched from Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket on Nov. 21, 2020 at 12:17 p.m. EST

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

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

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