NASA’s Earth Minute: Sea Level Rise

For more than 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our oceans to warm and glaciers to melt, resulting in sea level rise. Since 1880, the global sea level has risen 8 inches; by 2100, it is projected to rise another 1 to 4 feet.
