Icebergs float off the coast of Upernavik, Greenland, July 18, 2012. Every year, about 15,000 icebergs detach from the land and can float up to 40 degrees north and/or south, especially during summer months. The biggest icebergs can reach a surface of more than 11,550 square miles. In cold waters, icebergs can last about four years, but if the temperature rises above 41 degrees Fahrenheit, they can melt in a few days.
