[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 ...
This is a list of Antarctic ice shelves. An image of Antarctica differentiating its landmass (dark grey) from its ice shelves (minimum extent, light grey, and maximum extent, white) Edge of Ekstrom Ice Shelf
Ice caps accumulate snow on their upper surfaces, and ablate snow on their lower surfaces. [6] An ice cap in equilibrium accumulates and ablates snow at the same rate. The AAR is the ratio between the accumulation area and the total area of the ice cap, which is used to indicate the health of the glacier. [6]
A map of the Antarctic region, including the Antarctic Convergence and the 60th parallel south The Antarctic Plate. The Antarctic (/ æ n ˈ t ɑːr t ɪ k,-k t ɪ k /, US also / æ n t ˈ ɑːr t ɪ k,-k t ɪ k /; commonly / æ ˈ n ɑːr t ɪ k /) [Note 1] is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole.
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent , located in the Earth 's southern hemisphere , is centered asymmetrically around the South Pole and largely south of the Antarctic Circle .
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
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.

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).
