NASA Climate Watcher Waves Goodbye

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...

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

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

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 ...

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to tra...

TOPEX/Poseidon Launch

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...

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

Jason-1 Spacecraft Animation

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

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...

SSH and SST - Indian Ocean

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.

Sea Surface Height - Global Average from 1993 - 2011.

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...

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

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

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

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.

Watch the Jason-3 Science Briefing from Friday, Jan 15, 2016 - panelists discussed the science and research of the Jason-3 mission.
