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.

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...

Sea Level Isn't Level - Why it matters

For NASA scientist Severine Fournier, studying our planet knows no borders.

The ocean is responsible for Earth's mild climate and makes life on Earth possible for all creatures.

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

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.

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

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

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.

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

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...

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...

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.
