■ All specifications: Glaciation
At present, Antarctica – a vast continent centred on the South Pole – is unquestionably a land of ice. Glaciers cover approximately 98% of the land surface and in places are almost 5 km thick. In fact, there is so much ice that if melted it would raise global sea level by almost 60 m. Most of this ice is part of two ice sheets (see Box 1): the East and West Antarctic Ice Sheets (see Figure 1).
