The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi).
Continental glaciers, also known as ice sheet glaciers, are more massive than the Alpine or valley glaciers. They cover the entire continent except for the mountain tops. The ice sheets cover most of Canada and the Northern side of the United States in the last Ice age.
Ice, which covers 10 percent of Earth's surface, is disappearing rapidly. Select a topic below to see how climate change has affected glaciers, sea ice, and continental ice sheets worldwide.
During the 2020s ice sheets covered roughly 10 percent of Earth’s land area. Together, ice sheets and glaciers contain about 69 percent of the fresh water on Earth. The sections of ice sheets that extend outward from the coast and over the ocean are called ice shelves.
NASA's glaciers and ice sheet data help reveal ways these frozen giants influence our weather, climate, communities, and oceans. There are approximately 700,000 square kilometers of glaciers and ice sheets in the world located on every continent except Australia.
