[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 ...
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ft ...
Total loss of the Greenland ice sheet would increase regional temperatures in the Arctic by between 0.5 °C (0.90 °F) and 3 °C (5.4 °F), while the regional temperature in Antarctica is likely to go up by 1 °C (1.8 °F) after the loss of the West Antarctic ice sheet and 2 °C (3.6 °F) after the loss of the East Antarctic ice sheet.

This warming directly affects the flow of warm and cold water masses which make up the overturning circulation, and it also has negative impacts on sea ice cover in Southern Hemisphere, (which is highly reflective and so elevates the albedo of Earth's surface), as well as mass balance of Antarctica's ice shelves and peripheral glaciers.

[14] [15] In 1978, it was believed that the loss of the ice sheet would cause around 5 m (16 ft 5 in) of sea level rise, [90] Later improvements in modelling had shown that the collapse of the ice grounded below the sea level would cause ~3.3 m (10 ft 10 in) of sea level rise, [102] The additional melting of all the ice caps in West Antarctica ...
That's so cold scientists say it hurts to breathe. A new look at NASA satellite data revealed that Earth set a new record for coldest temperature recorded. It happened in August 2010 when it hit ...
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.
