We have some news: We’re moving! We won’t be far. Join us @NASAClimate to keep up with sea level science and climate change from NASA’s perspective. See you there!

During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tons of ice—enough to raise global sea levels by nearly a tenth of an inch (2.2 millimeters) in just two months. Down south, West Antarctic mass loss continues unabated. sealevel.nasa.gov/news/184/grace…

NASASeaLevel's tweet card. Greenland and Antarctica are melting—but how quickly and which areas are most affected? Nearly 20 years of satellite data provide key insights into these questions.

Observations from 11 satellite missions monitoring the Greenland and Antarctic ice sheets have revealed that the regions are losing ice six times faster than they were in the 1990s. sealevel.nasa.gov/news/183/green…

NASASeaLevel's tweet card. The two regions have lost 6.4 trillion tons of ice in three decades; unabated, this rate of melting could cause flooding that affects hundreds of millions of people by 2100.

Satellite data show that Antarctica and Greenland are losing hundreds of gigatonnes of (land-based) ice each year. But how big is just one gigatonne? Look ⬇️ for answers (and cool visualizations)! climate.nasa.gov/news/2933/visu…

Some parts of the Mississippi River Delta are disappearing due to sea-level rise, while other parts are not. A new NASA campaign, Delta-X, will be collecting data by air and by boat to better understand why. sealevel.nasa.gov/news/181/nasa-…

NASASeaLevel's tweet card. As sea levels rise, some areas of the Mississippi Delta are drowning, while others are actually gaining mass. NASA's Delta-X heads to the delta to figure out why.
