The more Greenland melts, the more Greenland melts. Here's why.

- The Arctic is currently warming about twice as fast as the rest of the world.

- Ice is white and bright and is able to reflect solar energy back into space. When it melts and exposes dark, open ocean, that open ocean absorbs more sunlight and more energy. This creates a kind of feedback loop.

- The darkness absorbs more solar energy — more sunlight. In turn, this accelerates the melt of the ice.
