Greenland’s ice sheet seems to stretch out forever. It slowly rises from the edge of the ocean to more than 10,000 feet in the center. Some of the ice is more than a hundred thousand years old and all of it originally fell here as snow. The research team shown here are trying to figure out just how this mountain of ice is moving into the sea, and how fast.
As we warm the planet, we're knocking this ice sheet out of balance — it’s losing more ice than it’s gaining. And that has big implications for rising sea levels. Six hundred million people live in coastal areas less than 32 feet above sea level. As the Greenland ice sheet melts away, an awful lot of those people are going to have to find somewhere else to live. That's a recipe for intense societal disruption — hunger, disease and conflict.
