For over 20 years, satellite altimeters have measured the sea surface height of our ever-changing oceans. This series of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015. Sea levels reflect changing currents (which tilt the sea surface), the redistribution of heat (which makes sea levels higher) and the long term rise in global sea levels that is the result of human-caused warming. The globally averaged rise is traced out in the bottom r

Sea Level 101: What Determines the Level of the Sea? - NASA Science

For over 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 ocean 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. :::LEARN MORE::: Key Indicators: Sea Level http://climate.nasa.gov/key_indicators/#seaLevel National Climate Assessment: Sea Level Rise http://
