How Much of the World's Ice Is in Antarctica?

Antarctica holds about 90% of the world's ice and 70% of its fresh water. The ice sheet averages 2.16 km thick, reaching up to 4.7 km in places, and contains roughly 30 million cubic kilometres (7.2 million cubic miles) of ice. If it all melted, global sea levels would rise by approximately 60 metres (200 feet).
