For reference, that’s about 19 football fields. The U.S. Antarctic Program also notes that if the ice sheet ever suddenly melted, it would raise the sea level worldwide an estimated 200 feet and submerge much of the Gulf and Atlantic coastal areas of the U.S. But the average temperature in Antarctica is -37°C, so the ice there is in no danger of melting.
The Antarctic Ice Sheet extends almost 14 million square kilometers (5.4 million square miles), roughly the area of the contiguous United States and Mexico combined. Antarctica is the highest, driest, coldest and windiest continent on Earth
