Oceans of Climate Change

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

Our World: How High is the Ocean?

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...

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

Decades of Discovery - How altimeters help us every day.

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

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

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

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.

B-roll for media. The Sentinel-6 Michael Freilich is an Earth-observing satellite that will collect data on sea level and how it changes over time. By measuring sea surface height, scientists world...

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...

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 level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise.

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

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

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.
