"And it's melting!" according to NASA. The deep ocean beneath Greenland is fueled by currents from the subtropics. This warm and salty water is melting the ice from the bottom up and much faster than the surface water.

A so-called "floating spoon" on Mars spotted by NASA's Curiosity rover is cooking up a storm on the Internet, but it's actually a cool rock formation sculpted over time by the Martian winds, officials with the space agency say.
