Today's Geo Quiz is as cold as ice. If you have a map of Antarctica, it's probably out of date.

Scientists say ice at both poles of the Earth is melting, as are glaciers and that's changing the landscape.

Now a giant chunk of what's called an "ice shelf" has broken off the Antarctic Peninsula. The British Antarctic Survey is pointing to the usual suspect: global warming.

The area of floating ice that's breaking up is about as large as New York City. Satellite images show the northern edge of the ice shelf's shattering into a mass of icebergs.

So before they float away - we want to know its name.

This ice shelf is located on the south west side of the Antarctic peninsula.

It was first mapped in 1910 by a French expedition, but it's named after an Australian polar explorer and geographer who photographed the ice from a plane in 1929.

We check in with a scientist who's watching this ice disappear before our very eyes in...
