Since 1880, global sea level has risen 20 centimeters (8 inches); by 2100, it is projected to rise another 30 to 122 centimeters (1 to 4 feet).
But what exactly is "sea level rise" and how do we know it's happening?
NASA/JPL Education specialist Ota Lutz explains the science behind Earth's rising seas and the very real impact it's having on communities -- even NASA! Check out the latest "Teachable Moment" blog to find out how to turn this key climate topic into a lesson for students aligned to Next Generation Science and Common Core Mathematics standards.
