Oceans of Climate Change

TOPEX/Poseidon Ground Tracks

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...

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

Sea Level Isn't Level - Why it matters

The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.

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

Sentinel-6 Michael Freilich will join a long-standing family of Earth observing satellites from NASA and European partners.

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.

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...

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.

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.

El Niño/La Niña - (12/1996 - 01/2000)

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.

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.

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...

For NASA engineer Shannon Statham, building spacecraft is all about being creative.

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.

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