Sentinel-6 Michael Freilich, the world's latest sea level satellite, is safely in orbit and ready to begin critical ocean measurements for the next five-and-a-half years.

Sea level rise can feel abstract, like something looming far off in the future. But if you want to see it happening in real-time, look no further than high-tide floods. (Image credit: City of Annapolis)

Up to two-thirds of NASA's infrastructure is potentially at risk of sea level rise. The agency is taking steps to prepare.

U.S. West Coast sea levels are rising faster than the global average. Learn about the forces that influence regional sea levels to better understand what's happening on this coast and whether it will continue. (Image credit: Jon Sullivan/Wikimedia Commons)

A warming climate is taking its toll on Greenland and Antarctica glaciers, melting them from above and below the surface. The more they melt, the higher sea levels rise.

Set for launch in November, the Earth-observing satellite will closely monitor sea level and provide atmospheric data to support weather forecasting and climate models.
