4.2 ANTARCTICA ICE CORE HISTORICAL TEMPERATURES
4.2.1 Vostok and EPICA data
Antarctica is the coldest and windiest place on Earth. It sits over the Earth's
southern pole and is covered by an ice sheet up to 4 km thick and over 4,000 km
across. It contains 70% of the Earth's fresh water and 90% of its ice, and has
existed in roughly its present form for around 15 million years. The ice sheet is
