The 5.4 million square-mile Antarctic ice sheet is by far the greatest mass of fresh water on earth. If all it were to melt, it would raise global sea levels some 70 meters (220 feet), driving human civilization inland, and ...

An iceberg is a large piece of ice from freshwater that has broken off from a snow-formed glacier or ice shelf and is floating in open water. It may subsequently become frozen into pack ice. Alternatively, it may come to rest on the seabed in shallower water, causing ice scour (also known as ice gouging) or becoming an ice island.
