[74] [75] [76] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
Around 98% of continental Antarctica is covered in ice up to 4.7 kilometres (2.9 mi) thick. [1] Antarctica's icy deserts have extremely low temperatures, high solar radiation, and extreme dryness. [2] Any precipitation that does fall usually falls as snow, and is restricted to a band around 300 kilometres (186 mi) from the coast.
Location and diagram of Lake Vostok, a prominent subglacial lake beneath the East Antarctic Ice Sheet.. East Antarctic Ice Sheet is located directly above the East Antarctic Shield – a craton (stable area of the Earth's crust) with the area of 10,200,000 km 2 (3,900,000 sq mi), which accounts for around 73% of the entire Antarctic landmass.

Lake Vostok (Russian: озеро Восток, romanized: ozero Vostok) is the largest of Antarctica's 675 known [3] subglacial lakes.Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level.
Global warming is also affecting Antarctica. The Larsen Ice Shelf or Larsen A is an ice sheet on the Antarctic Peninsula. The sheet broke in 1995, and then in 2000 an iceberg that is 4,250 sq mi (11,000 km 2) broke off the Ross Ice Shelf in Antarctica. [34] In 2002 Larsen B, which was 5,500 km 2 (2,100 sq mi), broke off.
A half-mile of ice isn't enough to suffocate life. A team of scientists who drilled into one of Antarctica's subglacial lakes last year says the lake is pretty well-packed with living things. The ...
The Ross Ice Shelf is the largest ice shelf of Antarctica (as of 2013, an area of roughly 500,809 square kilometres (193,363 sq mi) [1] and about 800 kilometres (500 mi) across: about the size of France). [2] It is several hundred metres thick.
The ice dome known as Dome Argus in East Antarctica is the highest Antarctic ice feature, at 4,091 metres (13,422 ft). It is one of the world's coldest and driest places—temperatures there may reach as low as −90 °C (−130 °F), and the annual precipitation is 1–3 cm (0.39–1.18 in).
