Ninety nine percent of all ice on Earth is located on top of Greenland and Antarctica. Each year, a little more of it melts into the ocean. Normally, it would take hundreds to thousands of years for it all to melt away. But what if something happened that caused a massive global melt overnight. Sea level would rise about 68 meters (223 feet). After that, disasters will follow. Watch this timeline video to find out what will happen in such a scenario.
